Scientific Process Flowchart Assessment (SPFA): A Method for Evaluating Changes in Understanding and Visualization of the Scientific Process in a Multidisciplinary Student Population.

PubMed

Wilson, Kristy J; Rigakos, Bessie

The scientific process is nonlinear, unpredictable, and ongoing. Assessing the nature of science is difficult with methods that rely on Likert-scale or multiple-choice questions. This study evaluated conceptions about the scientific process using student-created visual representations that we term "flowcharts." The methodology, Scientific Process Flowchart Assessment (SPFA), consisted of a prompt and rubric that was designed to assess students' understanding of the scientific process. Forty flowcharts representing a multidisciplinary group without intervention and 26 flowcharts representing pre- and postinstruction were evaluated over five dimensions: connections, experimental design, reasons for doing science, nature of science, and interconnectivity. Pre to post flowcharts showed a statistically significant improvement in the number of items and ratings for the dimensions. Comparison of the terms used and connections between terms on student flowcharts revealed an enhanced and more nuanced understanding of the scientific process, especially in the areas of application to society and communication within the scientific community. We propose that SPFA can be used in a variety of circumstances, including in the determination of what curricula or interventions would be useful in a course or program, in the assessment of curriculum, or in the evaluation of students performing research projects. © 2016 K.

Suryanti; Ibrahim, M.; Lede, N. S.

2018-01-01

The results of the Program for International Student Assessment (PISA) study on the scientific literacy of Indonesian students since the year 2000 have been still far below the international average score of 500. This could also be seen from the results of the science literacy test of 5th-grade students of primary school in Indonesia which showed that 60% of students are still at level ≤ 3 (value < 500). The students’ science literacy skills need to be improved by applying learning with a process skills approach. This study aims to describe the findings of classroom action research using a process skills approach to the science literacy level of primary students (n = 23). This research was conducted in 2 cycles with stages of planning, implementation, observation, and reflection. Students’ ability in scientific literacy was measured by using description and subjective tests of context domains, knowledge, competencies, and attitudes. In this study, researchers found an improvement in students’ science literacy skills when learning using a process skills approach. In addition, students’ scientific attitude is also more positive. In activities for learning science, students should be challenged as often as possible so that they have more practice using their scientific knowledge and skills to solve problems presented by teachers in the classroom.

Tools for Observation: Art and the Scientific Process

Pettit, E. C.; Coryell-Martin, M.; Maisch, K.

Art can support the scientific process during different phases of a scientific discovery. Art can help explain and extend the scientific concepts for the general public; in this way art is a powerful tool for communication. Art can aid the scientist in processing and interpreting the data towards an understanding of the concepts and processes; in this way art is powerful - if often subconscious - tool to inform the process of discovery. Less often acknowledged, art can help engage students and inspire scientists during the initial development of ideas, observations, and questions; in this way art is a powerful tool to develop scientific questions and hypotheses. When we use art as a tool for communication of scientific discoveries, it helps break down barriers and makes science concepts less intimidating and more accessible and understandable for the learner. Scientists themselves use artistic concepts and processes - directly or indirectly - to help deepen their understanding. Teachers are following suit by using art more to stimulate students' creative thinking and problem solving. We show the value of teaching students to use the artistic "way of seeing" to develop their skills in observation, questioning, and critical thinking. In this way, art can be a powerful tool to engage students (from elementary to graduate) in the beginning phase of a scientific discovery, which is catalyzed by inquiry and curiosity. Through qualitative assessment of the Girls on Ice program, we show that many of the specific techniques taught by art teachers are valuable for science students to develop their observation skills. In particular, the concepts of contour drawing, squinting, gesture drawing, inverted drawing, and others can provide valuable training for student scientists. These art techniques encourage students to let go of preconceptions and "see" the world (the "data") in new ways they help students focus on both large-scale patterns and small-scale details.

Where do Students Go Wrong in Applying the Scientific Method?

NASA Astrophysics Data System (ADS)

Rubbo, Louis; Moore, Christopher

2015-04-01

Non-science majors completing a liberal arts degree are frequently required to take a science course. Ideally with the completion of a required science course, liberal arts students should demonstrate an improved capability in the application of the scientific method. In previous work we have demonstrated that this is possible if explicit instruction is spent on the development of scientific reasoning skills. However, even with explicit instruction, students still struggle to apply the scientific process. Counter to our expectations, the difficulty is not isolated to a single issue such as stating a testable hypothesis, designing an experiment, or arriving at a supported conclusion. Instead students appear to struggle with every step in the process. This talk summarizes our work looking at and identifying where students struggle in the application of the scientific method. This material is based upon work supported by the National Science Foundation under Grant No. 1244801.

The Effects of Science Models on Students' Understanding of Scientific Processes

NASA Astrophysics Data System (ADS)

Berglin, Riki Susan

This action research study investigated how the use of science models affected fifth-grade students' ability to transfer their science curriculum to a deeper understanding of scientific processes. This study implemented a variety of science models into a chemistry unit throughout a 6-week study. The research question addressed was: In what ways do using models to learn and teach science help students transfer classroom knowledge to a deeper understanding of the scientific processes? Qualitative and quantitative data were collected through pre- and post-science interest inventories, observations field notes, student work samples, focus group interviews, and chemistry unit tests. These data collection tools assessed students' attitudes, engagement, and content knowledge throughout their chemistry unit. The results of the data indicate that the model-based instruction program helped with students' engagement in the lessons and understanding of chemistry content. The results also showed that students displayed positive attitudes toward using science models.

Constructing Scientific Arguments Using Evidence from Dynamic Computational Climate Models

NASA Astrophysics Data System (ADS)

Pallant, Amy; Lee, Hee-Sun

2015-04-01

Modeling and argumentation are two important scientific practices students need to develop throughout school years. In this paper, we investigated how middle and high school students ( N = 512) construct a scientific argument based on evidence from computational models with which they simulated climate change. We designed scientific argumentation tasks with three increasingly complex dynamic climate models. Each scientific argumentation task consisted of four parts: multiple-choice claim, openended explanation, five-point Likert scale uncertainty rating, and open-ended uncertainty rationale. We coded 1,294 scientific arguments in terms of a claim's consistency with current scientific consensus, whether explanations were model based or knowledge based and categorized the sources of uncertainty (personal vs. scientific). We used chi-square and ANOVA tests to identify significant patterns. Results indicate that (1) a majority of students incorporated models as evidence to support their claims, (2) most students used model output results shown on graphs to confirm their claim rather than to explain simulated molecular processes, (3) students' dependence on model results and their uncertainty rating diminished as the dynamic climate models became more and more complex, (4) some students' misconceptions interfered with observing and interpreting model results or simulated processes, and (5) students' uncertainty sources reflected more frequently on their assessment of personal knowledge or abilities related to the tasks than on their critical examination of scientific evidence resulting from models. These findings have implications for teaching and research related to the integration of scientific argumentation and modeling practices to address complex Earth systems.

Agriscience Student Engagement in Scientific Inquiry: Representations of Scientific Processes and Nature of Science.

Grady, Julie R; Dolan, Erin L; Glasson, George E

2010-01-01

Students' experiences with science integrated into agriscience courses contribute to their developing epistemologies of science. The purpose of this case study was to gain insight into the implementation of scientific inquiry in an agriscience classroom. Also of interest was how the tenets of the nature of science were reflected in the students' experiments. Participants included an agriscience teacher and her fifteen students who were conducting plant experiments to gain insight into the role of a gene disabled by scientists. Data sources included classroom observations, conversations with students, face-to-face interviews with the teacher, and students' work. Analysis of the data indicated that the teacher viewed scientific inquiry as a mechanical process with little emphasis on the reasoning that typifies scientific inquiry. Students' participation in their experiments also centered on the procedural aspects of inquiry with little attention to scientific reasoning. There was no explicit attention to the nature of science during the experiments, but the practice implied correct, incorrect, and underdeveloped conceptions of the nature of science. Evidence from the study suggests a need for collaboration between agriscience and science teacher educators to design and conduct professional development focused on scientific inquiry and nature of science for preservice and practicing teachers.

Assessing the impact participation in science journalism activities has on scientific literacy among high school students

NASA Astrophysics Data System (ADS)

Farrar, Cathy

As part of the National Science Foundation Science Literacy through Science Journalism (SciJourn) research and development initiative (http://www.scijourn.org ; Polman, Saul, Newman, and Farrar, 2008) a quasi-experimental design was used to investigate what impact incorporating science journalism activities had on students' scientific literacy. Over the course of a school year students participated in a variety of activities culminating in the production of science news articles for Scijourner, a regional print and online high school science news magazine. Participating teachers and SciJourn team members collaboratively developed activities focused on five aspects of scientific literacy: placing information into context, recognizing relevance, evaluating factual accuracy, use of multiple credible sources and information seeking processes. This study details the development process for the Scientific Literacy Assessment (SLA) including validity and reliability studies, evaluates student scientific literacy using the SLA, examines student SLA responses to provide a description of high school students' scientific literacy, and outlines implications of the findings in relation to the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012) and classroom science teaching practices. Scientifically literate adults acting as experts in the assessment development phase informed the creation of a scoring guide that was used to analyze student responses. Experts tended to draw on both their understanding of science concepts and life experiences to formulate answers; paying close attention to scientific factual inaccuracies, sources of information, how new information fit into their view of science and society as well as targeted strategies for information seeking. Novices (i.e., students), in contrast, tended to ignore factual inaccuracies, showed little understanding about source credibility and suggested unproductive information seeking strategies. However, similar to the experts, novices made references to both scientific and societal contexts. The expert/novice comparison provides a rough description of a developmental continuum of scientific literacy. The findings of this study including student results and Generalized Linear Mixed Modeling suggest that the incorporation of science journalism activities focused on STEM issues can improve student scientific literacy. Incorporation of a wide variety of strategies raised scores on the SLA. Teachers who included a writing and revision process that prioritized content had significantly larger gains in student scores. Future studies could broaden the description of high school student scientific literacy and measured by the SLA and provide alternative pathways for developing scientific literacy as envisioned by SciJourn and the NRC Frameworks.

Curriculum Alignment with Vision and Change Improves Student Scientific Literacy.

PubMed

Auerbach, Anna Jo; Schussler, Elisabeth E

2017-01-01

The Vision and Change in Undergraduate Biology Education final report challenged institutions to reform their biology courses to focus on process skills and student active learning, among other recommendations. A large southeastern university implemented curricular changes to its majors' introductory biology sequence in alignment with these recommendations. Discussion sections focused on developing student process skills were added to both lectures and a lab, and one semester of lab was removed. This curriculum was implemented using active-learning techniques paired with student collaboration. This study determined whether these changes resulted in a higher gain of student scientific literacy by conducting pre/posttesting of scientific literacy for two cohorts: students experiencing the unreformed curriculum and students experiencing the reformed curriculum. Retention of student scientific literacy for each cohort was also assessed 4 months later. At the end of the academic year, scientific literacy gains were significantly higher for students in the reformed curriculum ( p = 0.005), with those students having double the scientific literacy gains of the cohort in the unreformed curriculum. Retention of scientific literacy did not differ between the cohorts. © 2017 A. J. Auerbach and E. E. Schussler. CBE—Life Sciences Education © 2017 The American Society for Cell Biology.

Interactive, Online, Adsorption Lab to Support Discovery of the Scientific Process

NASA Astrophysics Data System (ADS)

Carroll, K. C.; Ulery, A. L.; Chamberlin, B.; Dettmer, A.

2014-12-01

Science students require more than methods practice in lab activities; they must gain an understanding of the application of the scientific process through lab work. Large classes, time constraints, and funding may limit student access to science labs, denying students access to the types of experiential learning needed to motivate and develop new scientists. Interactive, discovery-based computer simulations and virtual labs provide an alternative, low-risk opportunity for learners to engage in lab processes and activities. Students can conduct experiments, collect data, draw conclusions, and even abort a session. We have developed an online virtual lab, through which students can interactively develop as scientists as they learn about scientific concepts, lab equipment, and proper lab techniques. Our first lab topic is adsorption of chemicals to soil, but the methodology is transferrable to other topics. In addition to learning the specific procedures involved in each lab, the online activities will prompt exploration and practice in key scientific and mathematical concepts, such as unit conversion, significant digits, assessing risks, evaluating bias, and assessing quantity and quality of data. These labs are not designed to replace traditional lab instruction, but to supplement instruction on challenging or particularly time-consuming concepts. To complement classroom instruction, students can engage in a lab experience outside the lab and over a shorter time period than often required with real-world adsorption studies. More importantly, students can reflect, discuss, review, and even fail at their lab experience as part of the process to see why natural processes and scientific approaches work the way they do. Our Media Productions team has completed a series of online digital labs available at virtuallabs.nmsu.edu and scienceofsoil.com, and these virtual labs are being integrated into coursework to evaluate changes in student learning.

Characterizing High School Students' Written Explanations in Biology Laboratories

NASA Astrophysics Data System (ADS)

Peker, Deniz; Wallace, Carolyn S.

2011-03-01

The purpose of this qualitative interpretive research study was to examine high school students' written scientific explanations during biology laboratory investigations. Specifically, we characterized the types of epistemologies and forms of reasoning involved in students' scientific explanations and students' perceptions of scientific explanations. Sixteen students from a rural high school in the Southeastern United States were the participants of this research study. The data consisted of students' laboratory reports and individual interviews. The results indicated that students' explanations were primarily based on first-hand knowledge gained in the science laboratories and mostly representing procedural recounts. Most students did not give explanations based on a theory or a principle and did not use deductive reasoning in their explanations. The students had difficulties explaining phenomena that involved intricate cause-effect relationships. Students perceived scientific explanation as the final step of a scientific inquiry and as an account of what happened in the inquiry process, and held a constructivist-empiricist view of scientific explanations. Our results imply the need for more explicit guidance to help students construct better scientific explanations and explicit teaching of the explanatory genre with particular focus on theoretical and causal explanations.

The laboratory report: A pedagogical tool in college science courses

NASA Astrophysics Data System (ADS)

Ferzli, Miriam

When viewed as a product rather than a process that aids in student learning, the lab report may become rote, busywork for both students and instructors. Students fail to see the purpose of the lab report, and instructors see them as a heavy grading load. If lab reports are taught as part of a process rather than a product that aims to "get the right answer," they may serve as pedagogical tools in college science courses. In response to these issues, an in-depth, web-based tutorial named LabWrite (www.ncsu.edu/labwrite) was developed to help students and instructors (www.ncsu.edu/labwrite/instructors) understand the purpose of the lab report as grounded in the written discourse and processes of science. The objective of this post-test only quasi-experimental study was to examine the role that in-depth instruction such as LabWrite plays in helping students to develop skills characteristic of scientifically literate individuals. Student lab reports from an introductory-level biology course at NC State University were scored for overall understanding of scientific concepts and scientific ways of thinking. The study also looked at students' attitudes toward science and lab report writing, as well as students' perceptions of lab reports in general. Significant statistical findings from this study show that students using LabWrite were able to write lab reports that showed a greater understanding of scientific investigations (p < .003) and scientific ways of thinking (p < .0001) than students receiving traditional lab report writing instruction. LabWrite also helped students develop positive attitudes toward lab reports as compared to non-LabWrite users (p < .01). Students using LabWrite seemed to perceive the lab report as a valuable tool for determining learning objectives, understanding science concepts, revisiting the lab experience, and documenting their learning.

Introducing Pre-university Students to Primary Scientific Literature Through Argumentation Analysis

NASA Astrophysics Data System (ADS)

Koeneman, Marcel; Goedhart, Martin; Ossevoort, Miriam

2013-10-01

Primary scientific literature is one of the most important means of communication in science, written for peers in the scientific community. Primary literature provides an authentic context for showing students how scientists support their claims. Several teaching strategies have been proposed using (adapted) scientific publications, some for secondary education, but none of these strategies focused specifically on scientific argumentation. The purpose of this study is to evaluate a strategy for teaching pre-university students to read unadapted primary scientific literature, translated into students' native language, based on a new argumentation analysis framework. This framework encompasses seven types of argumentative elements: motive, objective, main conclusion, implication, support, counterargument and refutation. During the intervention, students studied two research articles. We monitored students' reading comprehension and their opinion on the articles and activities. After the intervention, we measured students' ability to identify the argumentative elements in a third unadapted and translated research article. The presented framework enabled students to analyse the article by identifying the motive, objective, main conclusion and implication and part of the supports. Students stated that they found these activities useful. Most students understood the text on paragraph level and were able to read the article with some help for its vocabulary. We suggest that primary scientific literature has the potential to show students important aspects of the scientific process and to learn scientific vocabulary in an authentic context.

Using Authentic Data in High School Earth System Science Research - Inspiring Future Scientists

NASA Astrophysics Data System (ADS)

Bruck, L. F.

2006-05-01

Using authentic data in a science research class is an effective way to teach students the scientific process, problem solving, and communication skills. In Frederick County Public Schools, MD a course has been developed to hone scientific research skills, and inspire interest in careers in science and technology. The Earth System Science Research course provides eleventh and twelfth grade students an opportunity to study Earth System Science using the latest information developed through current technologies. The system approach to this course helps students understand the complexity and interrelatedness of the Earth system. Consequently students appreciate the dynamics of local and global environments as part of a complex system. This course is an elective offering designed to engage students in the study of the atmosphere, biosphere, cryosphere, geosphere, and hydrosphere. This course allows students to utilize skills and processes gained from previous science courses to study the physical, chemical, and biological aspects of the Earth system. The research component of the course makes up fifty percent of course time in which students perform independent research on the interactions within the Earth system. Students are required to produce a scientific presentation to communicate the results of their research. Posters are then presented to the scientific community. Some of these presentations have led to internships and other scientific opportunities.

Introductory Biology Textbooks Under-Represent Scientific Process

PubMed Central

Duncan, Dara B.; Lubman, Alexandra; Hoskins, Sally G.

2011-01-01

Attrition of undergraduates from Biology majors is a long-standing problem. Introductory courses that fail to engage students or spark their curiosity by emphasizing the open-ended and creative nature of biological investigation and discovery could contribute to student detachment from the field. Our hypothesis was that introductory biology books devote relatively few figures to illustration of the design and interpretation of experiments or field studies, thereby de-emphasizing the scientific process. To investigate this possibility, we examined figures in six Introductory Biology textbooks published in 2008. On average, multistep scientific investigations were presented in fewer than 5% of the hundreds of figures in each book. Devoting such a small percentage of figures to the processes by which discoveries are made discourages an emphasis on scientific thinking. We suggest that by increasing significantly the illustration of scientific investigations, textbooks could support undergraduates’ early interest in biology, stimulate the development of design and analytical skills, and inspire some students to participate in investigations of their own.

NASA Astrophysics Data System (ADS)

Tomasek, Terry Morton

The purpose of this study was to examine and describe the ways various stakeholders (CBW project developer/coordinator, elementary and middle school teachers, and 5th through 8th grade students) envisioned, implemented and engaged in the citizen science project, eBird/Classroom BirdWatch. A multiple case study mixed-methods research design was used to examine student engagement in the cognitive processes associated with scientific inquiry as part of citizen science participation. Student engagement was described based on a sense of autonomy, competence, relatedness and intrinsic motivation. A goal of this study was to expand the taxonomy of differences between authentic scientific inquiry and simple inquiry to include those inquiry tasks associated with participation in citizen science by describing how students engaged in this type of science. This research study built upon the existing framework of cognitive processes associated with scientific inquiry described by Chinn and Malhotra (2002). This research provides a systematic analysis of the scientific processes and related reasoning tasks associated with the citizen science project eBird and the corresponding curriculum Classroom BirdWatch . Data consisted of responses to surveys, focus group interviews, document analysis and individual interviews. I suggest that citizen science could be an additional form of classroom-based science inquiry that can promote more authentic features of scientific inquiry and engage students in meaningful ways.

Wu, Hsin-Kai; Puntambekar, Sadhana

2012-12-01

Multiple external representations (MERs) have been widely used in science teaching and learning. Theories such as dual coding theory and cognitive flexibility theory have been developed to explain why the use of MERs is beneficial to learning, but they do not provide much information on pedagogical issues such as how and in what conditions MERs could be introduced and used to support students' engagement in scientific processes and develop competent scientific practices (e.g., asking questions, planning investigations, and analyzing data). Additionally, little is understood about complex interactions among scientific processes and affordances of MERs. Therefore, this article focuses on pedagogical affordances of MERs in learning environments that engage students in various scientific processes. By reviewing literature in science education and cognitive psychology and integrating multiple perspectives, this article aims at exploring (1) how MERs can be integrated with science processes due to their different affordances, and (2) how student learning with MERs can be scaffolded, especially in a classroom situation. We argue that pairing representations and scientific processes in a principled way based on the affordances of the representations and the goals of the activities is a powerful way to use MERs in science education. Finally, we outline types of scaffolding that could help effective use of MERs including dynamic linking, model progression, support in instructional materials, teacher support, and active engagement.

Struggles with learning about scientific models in a middle school science classroom

NASA Astrophysics Data System (ADS)

Loper, Suzanna Jane

Two important goals in science education are teaching students about the nature of science and teaching students to do scientific inquiry. Learning about scientific models is central to both of these endeavors, but studies have shown that students have very flawed and limited understandings of the nature and purposes of scientific models (Carey & Smith, 1993; Grosslight, Unger, & Jay, 1991; Lederman, 1992). In this dissertation I investigate the processes of teaching and learning about scientific models in an 8th grade classroom in an urban middle school. In order to do so, I examine recordings of student and teacher talk about models across a period of two months in which students completed two independent inquiry projects, using the Inquiry Island software and curriculum (Eslinger, 2004; Shimoda, White, & Frederiksen, 2002; White, Shimoda, & Frederiksen, 2000). My analysis draws on video records of small-group work and whole-class interactions, as well as on students' written work. I find that in this classroom, students struggled to understand the nature and purpose of scientific models. I analyze episodes in the classroom talk in which models appeared to be a source of trouble or confusion, and describe the ways in which the teacher attempted to respond to these troubles. I find that in many cases students appeared to be able to produce scientific models of the proper form, yet still struggled with displaying an understanding of what a model was, or of the functions of models in scientific research. I propose directions for further research and curriculum development in order to build on these findings. In particular, I argue, we need to design ways to help students engage in scientific modeling as a social and communicative practice, and to find ways to build from their everyday reasoning and argumentation practices. My research also reinforces the importance of looking at classroom talk, not just pre- and post-assessments, in order to understand teaching and learning as dynamic processes.

Questions addressed to something can induce metacognitive function to monitor a person’s thinking process. This study aims to describe the structure of the level of student questions based on thinking level and chemistry understanding level and describe how students use their metacognitive knowledge in asking. This research is a case study in chemistry learning, followed by 87 students. Results of the analysis revealed that the structure of thinking level of student question consists of knowledge question, understanding and application question, and high thinking question; the structure of chemistry understanding levels of student questions are a symbol, macro, macro-micro, macro-process, micro-process, and the macro-micro-process. The level Questioning skill of students to scientific articles more qualified than the level questioning skills of students to the teaching materials. The analysis result of six student interviews, a student question demonstrate the metacognitive processes with categories: (1) low-level metacognitive process, which is compiled based on questions focusing on a particular phrase or change the words; (2) intermediate level metacognitive process, submission of questions requires knowledge and understanding, and (3) high-level metacognitive process, the student questions posed based on identifying the central topic or abstraction essence of scientific articles.

"Beyond the walls": A research study of eighth-grade students mentored in a hospital setting

NASA Astrophysics Data System (ADS)

Grattan, Aileen

This research study was designed to evaluate twelve eighth-grade students participating in the fourth year of a mentoring program to determine what effect the mentoring experience would have on the students' sense of a scientific community, their understanding of scientific knowledge and process skills and attitudes toward science. The mentoring program was developed through a partnership established between the researcher, an eighth-grade science teacher at a junior high school, and an administrator of a local hospital, to provide educational opportunities for students mentored by medical professionals. The research design included qualitative and quantitative methods of analysis. The qualitative instruments were student journals and interviews. The quantitative instruments included the science subtest of the Stanford Nine Achievement Test, a Student Attitude Toward Science Survey (STATS), and a Hospital Questionnaire. The findings indicate that mentoring developed the students' understanding of a scientific community, revealed a wide range of attitudes and had a positive effect on the students' scientific knowledge and process skills. Finally, this research study has shown the benefits of mentoring as a model for teaching science in a community setting beyond the walls of the school.

Application of construal level and value-belief norm theories to undergraduate decision-making on a wildlife socio-scientific issue

Sutter, A. McKinzie; Dauer, Jenny M.; Forbes, Cory T.

2018-06-01

One aim of science education is to develop scientific literacy for decision-making in daily life. Socio-scientific issues (SSI) and structured decision-making frameworks can help students reach these objectives. This research uses value belief norm (VBN) theory and construal level theory (CLT) to explore students' use of personal values in their decision-making processes and the relationship between abstract and concrete problematization and their decision-making. Using mixed methods, we conclude that the level of abstraction with which students problematise a prairie dog agricultural production and ecosystem preservation issue has a significant relationship to the values students used in the decision-making process. However, neither abstraction of the problem statement nor students' surveyed value orientations were significantly related to students' final decisions. These results may help inform teachers' understanding of students and their use of a structured-decision making tool in a classroom, and aid researchers in understanding if these tools help students remain objective in their analyses of complex SSIs.

2013-01-01

The Partnerships for Informal Science Education in the Community (PISEC) program at the University of Colorado Boulder brings together university and community institutions to create an environment where K-12 students join with university educators to engage in inquiry-based scientific practices after school. In our original framing, these afterschool activities were developed to reinforce the traditional learning goals of the classroom, including mastering scientific content, skills and processes. Recently, the primary focus of the PISEC curriculum has been shifted towards the development of students' scientific identity, an explicit objective of informal learning environments. The new curriculum offers students more activity choices, affords opportunities for scientific drawings and descriptions, and provides incentive for students to design their own experiments. We have analyzed student science notebooks from both old and new curricula and find that with the redesigned curriculum, students exhibit increased agency and more instances of scientific communication while still demonstrating substantial content learning gains.

Teaching the process of science: faculty perceptions and an effective methodology.

PubMed

Coil, David; Wenderoth, Mary Pat; Cunningham, Matthew; Dirks, Clarissa

2010-01-01

Most scientific endeavors require science process skills such as data interpretation, problem solving, experimental design, scientific writing, oral communication, collaborative work, and critical analysis of primary literature. These are the fundamental skills upon which the conceptual framework of scientific expertise is built. Unfortunately, most college science departments lack a formalized curriculum for teaching undergraduates science process skills. However, evidence strongly suggests that explicitly teaching undergraduates skills early in their education may enhance their understanding of science content. Our research reveals that faculty overwhelming support teaching undergraduates science process skills but typically do not spend enough time teaching skills due to the perceived need to cover content. To encourage faculty to address this issue, we provide our pedagogical philosophies, methods, and materials for teaching science process skills to freshman pursuing life science majors. We build upon previous work, showing student learning gains in both reading primary literature and scientific writing, and share student perspectives about a course where teaching the process of science, not content, was the focus. We recommend a wider implementation of courses that teach undergraduates science process skills early in their studies with the goals of improving student success and retention in the sciences and enhancing general science literacy.

SEAS (Student Experiments At Sea): Helping Teachers Foster Authentic Student Inquiry in the Science Classroom

NASA Astrophysics Data System (ADS)

Goehring, L.; Kelsey, K.; Carlson, J.

2005-12-01

Teacher professional development designed to promote authentic research in the classroom is ultimately aimed at improving student scientific literacy. In addition to providing teachers with opportunities to improve their understanding of science through research experiences, we need to help facilitate similar learning in students. This is the focus of the SEAS (Student Experiments At Sea) program: to help students learn science by doing science. SEAS offers teachers tools and a framework to help foster authentic student inquiry in the classroom. SEAS uses the excitement of deep-sea research, as well as the research facilities and human resources that comprise the deep-sea scientific community, to engage student learners. Through SEAS, students have the opportunity to practice inquiry skills and participate in research projects along side scientists. SEAS is a pilot program funded by NSF and sponsored by the Ridge 2000 research community. The pilot includes inquiry-based curricular materials, facilitated interaction with scientists, opportunities to engage students in research projects, and teacher training. SEAS offers a framework of resources designed to help translate inquiry skills and approaches to the classroom environment, recognizing the need to move students along the continuum of scientific inquiry skills. This framework includes hands-on classroom lessons, Classroom to Sea labs where students compare their investigations with at-sea investigations, and a student experiment competition. The program also uses the Web to create a virtual ``scientific community'' including students. Lessons learned from this two year pilot emphasize the importance of helping teachers feel knowledgeable and experienced in the process of scientific inquiry as well as in the subject. Teachers with experience in scientific research were better able to utilize the program. Providing teachers with access to scientists as a resource was also important, particularly given the challenges of working in the deep-sea environment. Also, fostering authentic student investigations (i.e., working through preparatory materials, developing proposals, analyzing data and writing summary reports) is challenging to fit within the academic year. Nonetheless, teacher feedback highlights that the excitement generated by participation in real research is highly motivating. Further, students experience a ``paradigm shift'' in understanding evidence-based reasoning and the process of scientific discovery.

Development of Scientific Approach Based on Discovery Learning Module

Ellizar, E.; Hardeli, H.; Beltris, S.; Suharni, R.

2018-04-01

Scientific Approach is a learning process, designed to make the students actively construct their own knowledge through stages of scientific method. The scientific approach in learning process can be done by using learning modules. One of the learning model is discovery based learning. Discovery learning is a learning model for the valuable things in learning through various activities, such as observation, experience, and reasoning. In fact, the students’ activity to construct their own knowledge were not optimal. It’s because the available learning modules were not in line with the scientific approach. The purpose of this study was to develop a scientific approach discovery based learning module on Acid Based, also on electrolyte and non-electrolyte solution. The developing process of this chemistry modules use the Plomp Model with three main stages. The stages are preliminary research, prototyping stage, and the assessment stage. The subject of this research was the 10th and 11th Grade of Senior High School students (SMAN 2 Padang). Validation were tested by the experts of Chemistry lecturers and teachers. Practicality of these modules had been tested through questionnaire. The effectiveness had been tested through experimental procedure by comparing student achievement between experiment and control groups. Based on the findings, it can be concluded that the developed scientific approach discovery based learning module significantly improve the students’ learning in Acid-based and Electrolyte solution. The result of the data analysis indicated that the chemistry module was valid in content, construct, and presentation. Chemistry module also has a good practicality level and also accordance with the available time. This chemistry module was also effective, because it can help the students to understand the content of the learning material. That’s proved by the result of learning student. Based on the result can conclude that chemistry module based on discovery learning and scientific approach in electrolyte and non-electrolyte solution and Acid Based for the 10th and 11th grade of senior high school students were valid, practice, and effective.

Adadan, Emine; Yavuzkaya, Merve Nur

2018-03-01

This cross-sectional study examined how the progression and consistency of students' understanding of thermal concepts in everyday contexts changes across the grade levels. A total of 656 Turkish students from Grade 8 (age 13-14), Grade 10 (age 15-16), and the first year of college (age 19-20) participated in the study. The data were analysed using statistical procedures (descriptive and inferential). Findings indicated a substantial progression in the students' scientific understanding of thermal concepts across grade levels. In addition, the students' alternative conceptions about thermal concepts generally decreased in frequency across grade levels, but certain alternative conceptions were observed in every grade level to a similar extent. Even though the number of students who consistently used scientific ideas increased across grade levels, the number of students who consistently used non-scientific ideas decreased across grade levels. However, the number of students who used scientific and non-scientific ideas inconsistently generally increased as they progressed in the science curriculum. These findings can be associated with either fragmentation or alternative conceptions that result from the gradual enrichment processes students experience when they try to integrate scientific concepts into their conceptual frameworks.

In Brazil, scientific research is carried out mainly at universities, where professors coordinate research projects with the active participation of undergraduate and graduate students. However, there is no formal program for the teaching/learning of the scientific method. The objective of the present study was to evaluate the comprehension of the scientific method by students of health sciences who participate in scientific projects in an academic research laboratory. An observational descriptive cross-sectional study was conducted using Edgar Morin complexity as theoretical reference. In a semi-structured interview, students were asked to solve an abstract logical puzzle - TanGram. The collected data were analyzed using the hermeneutic-dialectic analysis method proposed by Minayo and discussed in terms of the theoretical reference of complexity. The students' concept of the scientific method is limited to participation in projects, stressing the execution of practical procedures as opposed to scientific thinking. The solving of the TanGram puzzle revealed that the students had difficulties in understanding questions and activities focused on subjects and their processes. Objective answers, even when dealing with personal issues, were also reflected on the students' opinions about the characteristics of a successful researcher. Students' difficulties concerning these issues may affect their scientific performance and result in poorly designed experiments. This is a preliminary study that should be extended to other centers of scientific research.

Research experiences for science teachers are an important mechanism for increasing classroom teachers' science content knowledge and facility with "real world" research processes. We have developed and implemented a summer scientific research and education workshop model for high school teachers and students which promotes classroom science inquiry projects and produces important research results supporting our overarching scientific agenda. The summer training includes development of a scientific research framework, design and implementation of preliminary studies, extensive field research and training in and access to instruments, measurement techniques and statistical tools. The development and writing of scientific papers is used to reinforce the scientific research process. Using these skills, participants collaborate with scientists to produce research quality data and analysis. Following the summer experience, teachers report increased incorporation of research inquiry in their classrooms and student participation in science fair projects. This workshop format was developed for an NSF Biocomplexity Research program focused on the interaction of urban climates, air quality and human response and can be easily adapted for other scientific research projects.

Being a Scientist While Teaching Science: Implementing Undergraduate Research Opportunities for Elementary Educators

Hock, Emily; Sharp, Zoe

2016-03-01

Aspiring teachers and current teachers can gain insight about the scientific community through hands-on experience. As America's standards for elementary school and middle school become more advanced, future and current teachers must gain hands-on experience in the scientific community. For a teacher to be fully capable of teaching all subjects, they must be comfortable in the content areas, equipped to answer questions, and able to pass on their knowledge. Hands-on research experiences, like the Summer Astronomy Research Experience at California Polytechnic University, pair liberal studies students with a cooperative group of science students and instructors with the goal of doing research that benefits the scientific community and deepens the team members' perception of the scientific community. Teachers are then able to apply the basic research process in their classrooms, inspire students to do real life science, and understand the processes scientists' undergo in their workplace.

Muglova, P. V.; Stoev, A. D.

2006-08-01

A model of research thinking development by teaching archaeoastronomy in specialized three-year extra-curriculum Astronomy programme and creation of favourable socio-educational surroundings is suggested. It is shown as a didactic system of conditions, influences and possibilities of answering specific hierarchic complex of personal needs in the 14 - 18 year age interval. Transformation of these needs in worldly values secures an active position of the students in the educational process and determines their personality development. It is also shown that the Archaeoastronomy School, as an educational environment, executes specific work of students' teaching, upbringing and progress as well as their inclusion in the real process of scientific research. Thus, they have the possibility of generating scientific ideas and obtaining results in the science archaeoastronomy. In consequence of this, their activity acquires social significance. Usages of this model of scientific school in the extra-curriculum Astronomy education reproduces norms and traditions of the real scientific research and directly relay subject content, cultural norms and values of archaeoastronomy in the educative process. Students' participation in archaeoastronomical expeditions, their competent work during the research of concrete archaeoastronomical objects create an investigation style of thinking and steady habits of scientific activity.

The use of writing assignments to help students synthesize content in upper-level undergraduate biology courses.

Sparks-Thissen, Rebecca L

2017-02-01

Biology education is undergoing a transformation toward a more student-centered, inquiry-driven classroom. Many educators have designed engaging assignments that are designed to help undergraduate students gain exposure to the scientific process and data analysis. One of these types of assignments is use of a grant proposal assignment. Many instructors have used these assignments in lecture-based courses to help students process information in the literature and apply that information to a novel problem such as design of an antiviral drug or a vaccine. These assignments have been helpful in engaging students in the scientific process in the absence of an inquiry-driven laboratory. This commentary discusses the application of these grant proposal writing assignments to undergraduate biology courses. © FEMS 2017. All rights reserved.

Student-centered education involving research experiences or inquiry have been shown to help undergraduate students understand, and become excited about, the process of scientific investigation. These benefits are particularly important for students in the early stages of their degree (Report and Kenny, http://naplesccsunysbedu/Pres/boyernsf/1998). However, embedding such experiences into the curriculum is particularly difficult when dealing with early stage students, who are in larger cohorts and often lack the background content knowledge necessary to engage with primary research literature and research level methods and equipment. We report here the design, delivery, assessment, and subsequent student learning outcomes of a 4-week practical module for 120 students at the beginning of their second year of university, which successfully engages students in designing cell culture experiments and in understanding the molecular processes and machinery involved in the basic cellular process of macropinocytosis.

Scientific writing: strategies and tools for students and advisors.

PubMed

Singh, Vikash; Mayer, Philipp

2014-01-01

Scientific writing is a demanding task and many students need more time than expected to finish their research articles. To speed up the process, we highlight some tools, strategies as well as writing guides. We recommend starting early in the research process with writing and to prepare research articles, not after but in parallel to the lab or field work. We suggest considering scientific writing as a team enterprise, which needs proper organization and regular feedback. In addition, it is helpful to select potential target journals early and to consider not only scope and reputation, but also decision times and rejection rates. Before submission, instructions to authors and writing guides should be considered, and drafts should be extensively revised. Later in the process editor's and reviewer's comments should be followed. Our tips and tools help students and advisors to structure the writing and publishing process, thereby stimulating them to develop their own strategies to success.

Science Inquiry as Knowledge Transformation: Investigating Metacognitive and Self-regulation Strategies to Assist Students in Writing about Scientific Inquiry Tasks

NASA Astrophysics Data System (ADS)

Collins, Timothy A.

2011-12-01

Science inquiry is central to the science education reform efforts that began in the early 1990's. It is both a topic of instruction and a process to be experienced. Student engagement in the process of scientific inquiry was the focus of this study. The process of scientific inquiry can be conceived as a two-part task. In the initial part of the task, students identify a question or problem to study and then carry out an investigation to address the issue. In the second part of the task, students analyze their data to propose explanations and then report their findings. Knowing that students struggle with science inquiry tasks, this study sought to investigate ways to help students become more successful with the communication demands of science inquiry tasks. The study took place in a high school chemistry class. Students in this study completed a total of three inquiry tasks over the course of one school year. Students were split into four experimental groups in order to determine the effect of goal setting, metacognitive prompts, and sentence stems on student inquiry tasks. The quality of the student written work was assessed using a scoring rubric familiar to the students. In addition, students were asked at four different times in the school year to respond to a self-efficacy survey that measured student self-efficacy for chemistry content and science inquiry processes. Student self-efficacy for the process of scientific inquiry was positive and did not change over the course of the study while student scores on the science inquiry tasks rose significantly. The metacognitive prompts and instruction in goal setting did not have any effect on student inquiry scores. Results related to the effect of the sentence stems were mixed. An analysis of student work indicated that students who received high marks on their initial inquiry task in this study were the ones that adopted the use of the sentence stems. Students who received low marks on their initial inquiry task did not tend to use the sentence stems. An analysis of word counts that compared the number of words used in the Framing section to the number of words used in the Analysis section indicated that students may have been using insufficient writing strategies. This study concludes with implications for classroom practice and recommendations for future research around student writing in the science classroom.

Holistic science: An understanding of science education encompassing ethical and social issues

NASA Astrophysics Data System (ADS)

Malekpour, Susan

Science has often been viewed, by the majority of our educators and the general public, as being objective and emotionless. Based on this view, our educators teach science in the same manner, objectively and in an abstract form. This manner of teaching has hindered our learners' ability for active learning and distanced them from the subject matter. In this action research, I have examined holistic science pedagogy in conjunction with a constructivism theory. In holistic science pedagogy, scientific knowledge is combined with subjective personal experiences and social issues. There is an interaction between student and scientific data when the student's context, relationships, and lived experiences that play a role in the scientific recognition of the world were incorporated into the learning process. In this pedagogical model, the factual content was viewed from the context of social and ethical implications. By empowering learners with this ability, science knowledge will no longer be exclusive to a select group. This process empowers the general population with the ability to understand scientific knowledge and therefore the ability to make informed decisions based on this knowledge. The goal was to make curriculum developers more conscious of factors that can positively influence the learning process and increase student engagement and understanding within the science classroom. The holistic approach to science pedagogy has enlightened and empowered our adult learners more effectively. Learners became more actively engaged in their own process of learning. Teachers must be willing to listen and implement student suggestions on improving the teaching/learning process. Teachers should be willing to make the effort in connecting with their students by structuring courses so the topics would be relevant to the students in relation to real world and social/ethical and political issues. Holistic science pedagogy strives for social change through the empowerment of adult learners with scientific knowledge. This research has demonstrated that learners can better understand the decision-making process and more easily relate their experiences, and therefore their knowledge, to social/political and ethical issues.

Creationism as a Misconception: Socio-cognitive conflict in the teaching of evolution

NASA Astrophysics Data System (ADS)

Foster, Colin

2012-09-01

This position paper argues that students' understanding and acceptance of evolution may be supported, rather than hindered, by classroom discussion of creationism. Parallels are drawn between creationism and other scientific misconceptions, both of the scientific community in the past and of students in the present. Science teachers frequently handle their students' misconceptions as they arise by offering appropriate socio-cognitive conflict, which highlights reasons to disbelieve one idea and to believe another. It is argued that this way of working, rather than outlawing discussion, is more scientific and more honest. Scientific truth does not win the day by attempting to deny its opponents a voice but by engaging them with evidence. Teachers can be confident that evolution has nothing to fear from a free and frank discussion in which claims can be rebutted with evidence. Such an approach is accessible to children of all ages and is ultimately more likely to drive out pre-scientific superstitions. It also models the scientific process more authentically and develops students' ability to think critically.

2011-01-01

Here we describe a semester-long, multipart activity called “Read and wRite to reveal the Research process” (R3) that was designed to teach students the elements of a scientific research paper. We implemented R3 in an advanced immunology course. In R3, we paralleled the activities of reading, discussion, and presentation of relevant immunology work from primary research papers with student writing, discussion, and presentation of their own lab findings. We used reading, discussing, and writing activities to introduce students to the rationale for basic components of a scientific research paper, the method of composing a scientific paper, and the applications of course content to scientific research. As a final part of R3, students worked collaboratively to construct a Group Research Paper that reported on a hypothesis-driven research project, followed by a peer review activity that mimicked the last stage of the scientific publishing process. Assessment of student learning revealed a statistically significant gain in student performance on writing in the style of a research paper from the start of the semester to the end of the semester.

Nurafni; Siswanto, R. D.; Azhar, E.

2018-01-01

A scientific approach is a learning process designed so that learners can actively construct concepts, encourage learners to find out from various sources through observation, and not just be told. Therefore, learning by scientific approach offers a solution, because the goals, principles, and stages of the scientific approach allow for a good understanding of the students. Because of the absence of teaching materials “polyhedron geometry based on scientific approach” which is widely published in Indonesia, then we need to develop the teaching materials. The results obtained in this study are the tasks presented on teaching materials with a scientific approach both in defining the cube and the beam, identify and solve problems related to the properties and elements of cubes and beams, making cube and beam nets, solving problems related to cube and beam nets, solving problems related to cube and beam surface area. Beginning with the difficulties students face. Then, based on the results of interviews with teachers and analysis of student difficulties on each indicator, researchers revise the teaching materials as needed. Teaching materials that have not found any more student difficulties then the teaching materials are considered valid and ready for use by teachers and students.

What can we learn from PISA?: Investigating PISA's approach to scientific literacy

NASA Astrophysics Data System (ADS)

Schwab, Cheryl Jean

This dissertation is an investigation of the relationship between the multidimensional conception of scientific literacy and its assessment. The Programme for International Student Assessment (PISA), developed under the auspices of the Organization for Economic Cooperation and Development (OECD), offers a unique opportunity to evaluate the assessment of scientific literacy. PISA developed a continuum of performance for scientific literacy across three competencies (i.e., process, content, and situation). Foundational to the interpretation of PISA science assessment is PISA's definition of scientific literacy, which I argue incorporates three themes drawn from history: (a) scientific way of thinking, (b) everyday relevance of science, and (c) scientific literacy for all students. Three coordinated studies were conducted to investigate the validity of PISA science assessment and offer insight into the development of items to assess scientific 2 literacy. Multidimensional models of the internal structure of the PISA 2003 science items were found not to reflect the complex character of PISA's definition of scientific literacy. Although the multidimensional models across the three competencies significantly decreased the G2 statistic from the unidimensional model, high correlations between the dimensions suggest that the dimensions are similar. A cognitive analysis of student verbal responses to PISA science items revealed that students were using competencies of scientific literacy, but the competencies were not elicited by the PISA science items at the depth required by PISA's definition of scientific literacy. Although student responses contained only knowledge of scientific facts and simple scientific concepts, students were using more complex skills to interpret and communicate their responses. Finally the investigation of different scoring approaches and item response models illustrated different ways to interpret student responses to assessment items. These analyses highlighted the complexities of students' responses to the PISA science items and the use of the ordered partition model to accommodate different but equal item responses. The results of the three investigations are used to discuss ways to improve the development and interpretation of PISA's science items.

Scientists in the making: An ethnographic investigation of scientific processes as literate practice in an elementary classroom

NASA Astrophysics Data System (ADS)

Crawford, Teresa Jo

This study explored the issue of literacy in science by examining how the social and academic literate practices in an elementary classroom formed the basis for learning across the curriculum, with a specific focus on the disciplinary field of science. Through the study of classroom interaction, issues related to student knowledge and ability were addressed as they pertain to scientific literacy in the context of science education reform. The theoretical framework guiding this study was drawn from sociocultural studies of scientific communities and interactional ethnography in education. To investigate the literate practices of science in a school setting, data were collected over a two-year period with the same teacher in her third grade and then her fourth/fifth grade classroom. Data were collected through participant observation in the form of fieldnotes, video data, interviews, and various artifacts (e.g., writings, drawings, teaching protocols). Using ethnographic and sociolinguistic methods of analysis this work examined classroom members' discursive practices to illustrate the role that discourse plays in creating opportunities for engagement in, and access to, scientific knowledge. These analyses revealed that the discursive actions and practices among members of this classroom shaped a particular type of learning environment that was process-oriented and inquiry based. It was shown that this learning environment afforded opportunities for students to engage in the processes of science outside the official, planned curriculum, often leading to whole class scientific investigations and discussions. Additionally, within this classroom community students were able to draw on multiple discourses to display their knowledge of scientific concepts and practices. Overall, this study found that the literate practices of this classroom community, as they were socially constructed among members, contributed to opportunities for students to practice science and demonstrate scientific literacy.

Re/Production of science process skills and a scientific ethos in an early childhood classroom

NASA Astrophysics Data System (ADS)

Kirch, Susan A.

2007-10-01

Many educators and researchers are convinced that age limits what students can learn and achieve in science. Elementary school curricula focus on isolated process skills under the faulty assumption that young students are not capable of combining the process skills and content knowledge necessary for reasoning scientifically. In the present study, I demonstrate that many process skills are produced in conversations between second grade students and between these students and their teachers, including: questioning, hypothesis formation, experimental design, identifying relevant evidence, critical analysis of hypotheses and predictions, hypothesis reconstruction, and variable identification. Through conversation analysis I show that most classroom community members adopted the role of skeptic at some time, but there was a strong tendency to defer to authoritative sources when resolving debates. This latter observation led to further investigation of when and how authoritative sources were consulted and used, and when and how a skeptical stance was taken. I show that, as students used science process skills and interacted with each other and teacher-mediators, community practices, values, and mores were shaped and an ethos of science began to emerge. It is my contention that this ethos often emerges unconsciously as part of the community's dynamic set of rules and schema. Teachers who are attuned to the tension between open-mindedness and skepticism, and how they and their students cope with this dialectic, however, can actively shape the scientific ethos of their classroom community.

Using Cogenerative Dialogs to Improve Science Teaching and Learning: Challenges and Solutions in High School Students' Internships

NASA Astrophysics Data System (ADS)

Hsu, Pei-Ling

2018-05-01

Internships in science research settings have received increasing attention as a means of helping students construct appropriate understandings, practices, tools, and language in scientific activities. To advance student-scientist partnerships beyond the status quo, the study aimed to investigate how cogenerative dialogs (cogens) may help high school students and scientists identify and address challenges collectively. The analysis identified nine major challenges discussed during cogens: (1) the quality and progress of scientific practice in laboratories, (2) the quality of scientists'/assistants' instructions in classrooms, (3) the quality of student participation in classrooms and homework, (4) students' absences, including arriving late or leaving early, (5) the quality of administrative support, (6) preparation for scientific presentations, (7) the process of deciding project topics, (8) students' peer interactions and communication, and (9) students' physiological needs. The three most salient challenges were "the quality and progress of scientific practice in laboratories" (39%), "the quality of scientists'/assistants' instructions in classrooms" (20%), and "the quality of student participation in classrooms and homework" (17%). The study shows that cogens allowed students and scientists to agree on teaching modifications that positively influenced teaching and learning processes during the internship, such that issues were reduced from the beginning to the closing stages. Importantly, the challenges and solutions identified by students and scientists in this study provide accounts of first-hand experience as well as insights to aid program directors or coordinators in designing a learning environment that can foster effective practice for internships by avoiding the issues identified in the study.

A core component of public scientific literacy, and thereby informed decision-making, is the ability of individuals to reason about complex systems. In response to students having difficulty learning about complex systems, educational research suggests that conceptual representations, or mental models, may help orient student thinking. Mental models provide a framework to support students in organizing and developing ideas. The PMC-2E model is a productive tool in teaching ideas of modeling complex systems in the classroom because the conceptual representation framework allows for self-directed learning where students can externalize systems thinking. Beyond mental models, recent work emphasizes the importance of facilitating integration of authentic science into the formal classroom. To align these ideas, a university class was developed around the theme of carnivore ecology, founded on PMC-2E framework and authentic scientific data collection. Students were asked to develop a protocol, collect, and analyze data around a scientific question in partnership with a scientist, and then use data to inform their own learning about the system through the mental model process. We identified two beneficial outcomes (1) scientific data is collected to address real scientific questions at a larger scale and (2) positive outcomes for student learning and views of science. After participating in the class, students report enjoying class structure, increased support for public understanding of science, and shifts in nature of science and interest in pursuing science metrics on post-assessments. Further work is ongoing investigating the linkages between engaging in authentic scientific practices that inform student mental models, and how it might promote students' systems-thinking skills, implications for student views of nature of science, and development of student epistemic practices.

Video Creation: A Tool for Engaging Students to Learn Science

NASA Astrophysics Data System (ADS)

Courtney, A. R.

2016-12-01

Students today process information very differently than those of previous generations. They are used to getting their news from 140-character tweets, being entertained by You-Tube videos, and Googling everything. Thus, traditional passive methods of content delivery do not work well for many of these millennials. All students, regardless of career goals, need to become scientifically literate to be able to function in a world where scientific issues are of increasing importance. Those who have had experience applying scientific reasoning to real-world problems in the classroom will be better equipped to make informed decisions in the future. The problem to be solved is how to present scientific content in a manner that fosters student learning in today's world. This presentation will describe how the appeal of technology and social communication via creation of documentary-style videos has been used to engage students to learn scientific concepts in a university non-science major course focused on energy and the environment. These video projects place control of the learning experience into the hands of the learner and provide an opportunity to develop critical thinking skills. Students discover how to locate scientifically reliable information by limiting searches to respected sources and synthesize the information through collaborative content creation to generate a "story". Video projects have a number of advantages over research paper writing. They allow students to develop collaboration skills and be creative in how they deliver the scientific content. Research projects are more effective when the audience is larger than just a teacher. Although our videos are used as peer-teaching tools in the classroom, they also are shown to a larger audience in a public forum to increase the challenge. Video will be the professional communication tool of the future. This presentation will cover the components of the video production process and instructional lessons learned over a seven-year period.

Agriscience Student Engagement in Scientific Inquiry: Representations of Scientific Processes and Nature of Science

PubMed Central

Grady, Julie R.; Dolan, Erin L.; Glasson, George E.

2013-01-01

Students’ experiences with science integrated into agriscience courses contribute to their developing epistemologies of science. The purpose of this case study was to gain insight into the implementation of scientific inquiry in an agriscience classroom. Also of interest was how the tenets of the nature of science were reflected in the students’ experiments. Participants included an agriscience teacher and her fifteen students who were conducting plant experiments to gain insight into the role of a gene disabled by scientists. Data sources included classroom observations, conversations with students, face–to–face interviews with the teacher, and students’ work. Analysis of the data indicated that the teacher viewed scientific inquiry as a mechanical process with little emphasis on the reasoning that typifies scientific inquiry. Students’ participation in their experiments also centered on the procedural aspects of inquiry with little attention to scientific reasoning. There was no explicit attention to the nature of science during the experiments, but the practice implied correct, incorrect, and underdeveloped conceptions of the nature of science. Evidence from the study suggests a need for collaboration between agriscience and science teacher educators to design and conduct professional development focused on scientific inquiry and nature of science for preservice and practicing teachers.

Characterizing Students' Attempts to Explain Observations from Practical Work: Intermediate Phases of Understanding

NASA Astrophysics Data System (ADS)

Mestad, Idar; Kolstø, Stein Dankert

2017-10-01

This study aims to characterize a group of students' preliminary oral explanations of a scientific phenomenon produced as part of their learning process. The students were encouraged to use their own wordings to test out their own interpretation of observations when conducting practical activities. They presented their explanations orally in the whole class after having discussed and written down an explanation in a small group. The data consists of transcribed video recordings of the presented explanations, observation notes, and interviews. A genre perspective was used to characterize the students' explanations together with analysis of the students use of scientific terms, gestures, and the language markers "sort of" and "like." Based on the analysis we argue to separate between event-focused explanations, where the students describe how objects move, and object-focused explanations, where the students describe object properties and interactions. The first type uses observable events and few scientific terms, while the latter contains object properties and tentative use of scientific terms. Both types are accompanied by an extensive use of language markers and gestures. A third category, term-focused explanations, is used when the students only provide superficial explanations by expressing scientific terms. Here, the students' use of language markers and gestures are low. The analyses shows how students' explanations can be understood as tentative attempts to build on their current understanding and observations while trying to reach out for a deeper and scientific way of identifying observations and building explanations and new ways of talking.

The Impact of Student Self-efficacy on Scientific Inquiry Skills: An Exploratory Investigation in River City, a Multi-user Virtual Environment

NASA Astrophysics Data System (ADS)

Ketelhut, Diane Jass

2007-02-01

This exploratory study investigated data-gathering behaviors exhibited by 100 seventh-grade students as they participated in a scientific inquiry-based curriculum project delivered by a multi-user virtual environment (MUVE). This research examined the relationship between students' self-efficacy on entry into the authentic scientific activity and the longitudinal data-gathering behaviors they employed while engaged in that process. Three waves of student behavior data were gathered from a server-side database that recorded all student activity in the MUVE; these data were analyzed using individual growth modeling. The study found that self-efficacy correlated with the number of data-gathering behaviors in which students initially engaged, with high self-efficacy students engaging in more data gathering than students with low self-efficacy. Also, the impact of student self-efficacy on rate of change in data gathering behavior differed by gender. However, by the end of their time in the MUVE, initial student self-efficacy no longer correlated with data gathering behaviors. In addition, students' level of self-efficacy did not affect how many different sources from which they chose to gather data. These results suggest that embedding science inquiry curricula in novel platforms like a MUVE might act as a catalyst for change in students' self-efficacy and learning processes.

One of the greatest challenges instructors face is getting students to connect with the subject in a manner that encourages them to learn. In this essay, we describe the redesign of our Developmental Biology course to foster a deeper connection between students and the field of developmental biology. In our approach, we created a community of scientific practice focused on the investigation of environmental impacts on embryonic development and informed by popular and scientific media, the students' own questions, and the instructor. Our goals were to engage students in meaningful ways with the material, to develop students' science process skills, and to enhance students' understanding of broad principles of developmental biology. Though significant challenges arose during implementation, assessments indicate using this approach to teach undergraduate developmental biology was successful.

Introducing Ocean Science Research to Two-Year College (2YC) Students Through Inquiry-Based Experiences

An effective approach to introduce 2YC students to ocean science research is through propagating inquiry-based experiences into existing geosciences courses using a series of research activities. The proposed activity is based on scientific ocean drilling, where students begin their research experience (pre-field activity) by reading articles from scientific journals and analyzing and interpreting core and log data on a specific research topic. At the end of the pre-field activity, students will visit the Gulf Coast Repository to examine actual cores, smear slides, thin sections etc. After the visit, students will integrate findings from their pre-field and field activities to produce a term paper. These simple activities allow students to experience in the iterative process of scientific research, illuminates how scientists approach ocean science, and can be the hook to get students interested in pursuing ocean science as a career.

With the copious amount of science and pseudoscience reported on by non-experts in the media, it is critical for educators to help students develop into scientifically literate citizens. One of the most direct ways to help students develop deep scientific understanding and the skills to critically question the information they encounter is to bring science into their daily experiences and to contextualize scientific inquiry within the classroom. Our work aims to use a systems-based models approach to engage students in science, in both formal and informal contexts. Using the Understanding Global Change (UGC) and the Understanding Science models developed at the Museum of Paleontology at UC Berkeley, high school students from Arizona were tasked with developing a viable citizen science program for use at the Center for Alaskan Coastal Studies in Homer, Alaska. Experts used the UGC model to help students define why they were doing the work, and give context to the importance of citizen science. Empowered with an understanding of the scientific process, excited by the purpose of their work and how it could contribute to the scientific community, students whole-heartedly worked together to develop intertidal monitoring protocols for two locations while staying at Peterson Bay Field Station, Homer. Students, instructors, and scientists used system models to communicate and discuss their understanding of the biological, physical, and chemical processes in Kachemak Bay. This systems-based models approach is also being used in an integrative high school physics, chemistry, and biology curriculum in a truly unprecedented manner. Using the Understanding Global Change framework to organize curriculum scope and sequence, the course addresses how the earth systems work, how interdisciplinary science knowledge is necessary to understand those systems, and how scientists and students can measure changes within those systems.

Scientific process skills (SPS) are an intellectual skill to build knowledge, solve problems scientifically, train thinking skills as well as a very important part of the inquiry process and contribute to scientific literacy. Therefore, SPS is very important to be developed. This study aims to develop Student Worksheets (SW) that can trace SPS through basic physics experiments (BPE) on Melde’s law. This research uses R&D method involving 18 physics education department students who take the BPE course as a sample. The research instrument uses an SW designed with a SPS approach that have been reviewed and judged by expert, which includes observing, communicating, classifying, measuring, inferring, predicting, identifying variable, constructing hypothesis, defining variable operationally, designing experiment, acquiring and processing data to conclusions. The result of the research shows that the student’s SPS has not been trained optimally, the students’ answers are not derived from the observations and experiments conducted but derived from the initial knowledge of the students, as well as in the determination of experimental variables, inferring and hypothesis. This result is also supported by a low increase of conceptual content on Melde’s law with n-gain of 0.40. The research findings are used as the basis for the redesign of SW.

2016-01-01

Scientific writing is an important communication and learning tool in neuroscience, yet it is a skill not adequately cultivated in introductory undergraduate science courses. Proficient, confident scientific writers are produced by providing specific knowledge about the writing process, combined with a clear student understanding about how to think about writing (also known as metacognition). We developed a rubric for evaluating scientific papers and assessed different methods of using the rubric in inquiry-based introductory biology classrooms. Students were either 1) given the rubric alone, 2) given the rubric, but also required to visit a biology subject tutor for paper assistance, or 3) asked to self-grade paper components using the rubric. Students who were required to use a peer tutor had more negative attitudes towards scientific writing, while students who used the rubric alone reported more confidence in their science writing skills by the conclusion of the semester. Overall, students rated the use of an example paper or grading rubric as the most effective ways of teaching scientific writing, while rating peer review as ineffective. Our paper describes a concrete, simple method of infusing scientific writing into inquiry-based science classes, and provides clear avenues to enhance communication and scientific writing skills in entry-level classes through the use of a rubric or example paper, with the goal of producing students capable of performing at a higher level in upper level neuroscience classes and independent research.

Foong, Chan-Choong; Daniel, Esther G. S.

2013-09-01

This paper argues the possible simultaneous development and transfer of students' argumentation skills from one socio-scientific issue to another in a Confucian classroom. In Malaysia, the Chinese vernacular schools follow a strict Confucian philosophy in the teaching and learning process. The teacher talks and the students listen. This case study explored the transfer of argumentation skills across two socio-scientific issues in such a Form 2 (8th grade) classroom. An instructional support to complement the syllabus was utilised. The teaching approach in the instructional support was more constructivist in nature and designed to introduce argumentation skills which is uncommon in a Confucian classroom. The two socio-scientific issues were genetically modified foods and deforestation. This paper presents a part of the bigger case study that was conducted. Data collected from written arguments were analysed using an analytical framework built upon Toulmin's ideas. The whole class analysis indicated progression in students' argumentation skills in their ability to give more valid grounds and rebuttals during the transfer. The individual analysis suggests progression in the majority of students' performance, while several students demonstrated non-progression when they faced a different socio-scientific issue.

Demystifying Scientific Data ­ Using Earth Science to Teach the Scientific Method

The collection of large quantities of data and their subsequent analyses are important components of any scientific process, particularly at research institutes such as MIT's Haystack Observatory, where the collection and analyses of data is crucial to research efforts. Likewise, a recent study on science education concluded that students should be introduced to analyzing evidence and hypotheses, to critical thinking - including appropriate skepticism, to quantitative reasoning and the ability to make reasonable estimates, and to the role of uncertainty and error in science. In order to achieve this goal with grades 9-12 students and their instructors, we developed lesson plans and activities based on atmospheric science and geodetic research at Haystack Observatory. From the complex steps of experimental design, measurement, and data analysis, students and teachers will gain insight into the scientific research processes as they exist today. The use of these space weather and geodesy activities in classrooms will be discussed. Space Weather: After decades of data collection with multiple variables, space weather is about as complex an area of investigation as possible. Far from the passive relationship between the Sun and Earth often taught in the early grades, or the beautiful auroras discussed in high school, there are complex and powerful interactions between the Sun and Earth. In spite of these complexities, high school students can learn about space weather and the repercussions on our communication and power technologies. Starting from lessons on the basic method of observing space weather with incoherent scatter radar, and progressing to the use of simplified data sets, students will discover how space weather affects Earth over solar cycles and how severe solar activity is measured and affects the Earth over shorter time spans. They will see that even from complex, seemingly ambiguous data with many variables and unknowns, scientists can gain valuable insights into complicated processes. Geodesy: Students learn about tectonic plate theory in middle school to explain continental drift, but have no idea about how it is determined. By learning about the process, students become more familiar with measurement, uncertainty, and error. Students who analyze continental drift using observations from very long baseline interferometry (VLBI) will discover the current limits of scientific measurement (approximately one part in a billion) and see how even these data may contain unmodeled effects. In both projects the process of understanding data will give the students a better picture of how science works. These lessons and activities were created under the Research Experiences for Teachers program of the National Science Foundation.

We report the progress made in a two-year NASA funded EPO project, which takes advantage of the latest WebGIS technology to bring real NASA data to high school classrooms. The only requirement for the WebGIS is an Internet connection and a standard web browser allowing the widest possible accessibility. The overall goal of the project is to enhance the students' interest in science and to directly engage them in the actual process of conducting scientific research with a real scientific research question and real scientific datasets. The students will be exposed to the full process of conducting real scientific investigation: collecting evidence, analyzing data, formulating alternative hypotheses, and communicating and debating with their peers about their findings. Such opportunities are rarely available in the middle through high school level. We have set up the WebGIS (http://marsproject.niu.edu) and have completed the student and teacher tutorials. The standard-based student modules are being finalized and tested by two Master teachers this semester. A training workshop for teachers will be held Spring 2007. Approximately twenty classrooms will be participating fully by the 2007-08 school year.

An investigation of Taiwanese graduate students' level of civic scientific literacy

NASA Astrophysics Data System (ADS)

Lee, Yu-Mei

2003-07-01

Professionals in a variety of disciplines have stressed the importance of advancing the scientific literacy of all citizens in a democratic and science- and technology-based society. Taiwan has been striving hard to advance its democracy and heavily relies on a knowledge-based economy. The high rank Taiwan receives in international comparisons demonstrates Taiwan's high achievement in science at the middle school level. However, no empirical evidence has been collected to examine whether this high achievement at the middle school level promises a high level of scientific literacy in adults. This study investigated the level of scientific literacy of Taiwanese graduate students using Miller's framework of three dimensions of civic scientific literacy, including: (1) a vocabulary of basic scientific constructs, (2) an understanding of the process of scientific inquiry, and (3) some level of understanding of the impact of science and technology on individuals and on society. A web-based questionnaire was employed to survey Taiwanese graduate students studying in three different types of graduate schools and eleven academic fields. A total of 525 responses were collected. In addition, following the survey, eight participants were purposefully selected for individual interviews in order to obtain additional information on participants' scientific literacy. Descriptive statistical analyses were computed to summarize the participants' overall responses to each of the survey sections. Regression models using dummy coding of categorical variables (i.e., gender, school type, and academic areas) were performed to examine whether significant differences exist among different groups. The major findings suggest that: (1) Taiwanese graduate students' civic scientific literacy is not at a satisfactory level; (2) the participants carry mixed attitudes toward science and technology, (3) Taiwanese graduate students are not very attentive to new information of science and technology; (4) all three categorical variables had an impact on the participants' understanding of basic scientific constructs, while only school type had an effect on the participants' understanding of the scientific inquiry process; and (5) the interview results did not support the survey results. The researcher suggests that further studies are required to determine the reasons behind these findings.

Although the discipline of cell biology (CB) is part of the curricula of predoctoral dental schools, students often fail to recognize its practical relevance. The aim of this study was to assess the effectiveness of a practical-theoretical project-based course in closing the gaps among CB, scientific research, and dentistry for dental students. A project-based learning course was developed with nine sequential lessons to evaluate 108 undergraduate dental students enrolled in CB classes of a Brazilian school of dentistry during 2013-16. To highlight the relevance of in vitro studies in the preclinical evaluation of dental materials at the cellular level, the students were challenged to complete the process of drafting a protocol and performing a cytocompatibility assay for a bone substitute used in dentistry. Class activities included small group discussions, scientific database search and article presentations, protocol development, lab experimentation, and writing of a final scientific report. A control group of 31 students attended only one laboratory class on the same theme, and the final reports were compared between the two groups. The results showed that the project-based learning students had superior outcomes in acknowledging the relevance of in vitro methods during biocompatibility testing. Moreover, they produced scientifically sound reports with more content on methodological issues, the relationship with dentistry, and the scientific literature than the control group (p<0.05). The project-based learning students also recognized a higher relevance of scientific research and CB to dental practice. These results suggest that a project-based approach can help contextualize scientific research in dental curricula.

This multiple case study examined the coauthorship process in research laboratories of different university departments. The study focused on two cases comprising five writing teams, one in biochemistry and microbiology and four in earth and ocean sciences. The role of the research supervisor, the role of the student (graduate and postgraduate), the interaction of the supervisor and the student, the activities and processes inherent in the coauthorship process, and the student's beliefs, expertise, scientific writing, and entry into an academic discourse community were documented utilizing multiple sources of data and methods. Several activities and processes were found to be common across all coauthorship teams, including aspects of planning, drafting, and revising. Elements of scientific and writing expertise, facets of enculturation into scientific research and discourse communities, academic civility, and the dynamics of collaborative groups also were apparent. There was healthy tension and mutual respect in the research groups as they attempted to make sense of science, report their results clearly and persuasively, and share the responsibilities of expertise. The novice scientists came to appreciate that the writing, editing, and revising process influenced the quality of the science as well as the writing.

This study investigates the effectiveness of the online Flash game Disease Defenders in producing knowledge gains for concepts related to the scientific process. Disease Defenders was specifically designed to model how the scientific process is central to a variety of disciplines and science careers. An additional question relates to the game's ability to shift attitudes toward science. Middle school classes from grades six to eight were assigned to the experimental group (n = 489) or control group (n = 367) and asked to participate in a three-session intervention. The sessions involved completing a pretest, a game play session, and taking a posttest. Students in the experimental group played Disease Defenders while students in the control group played an alternative science game. Results showed a significant increase in mean science knowledge scores for all grades in the experimental group, with sixth grade and seventh grade students gaining more knowledge than eighth grade students. Additionally, results showed a significant positive change in science attitudes only among sixth graders, who also rated their satisfaction with the game more favorably than students in higher grades. No differences in mean test scores were found between genders for science knowledge or science attitudes, suggesting that the game is equally effective for males and females.

This year-long, quasi-experimental study investigated the impact of the use of netbook computers and interactive science software on fifth-grade students' science learning processes, academic achievement, and interest in further science, technology, engineering, and mathematics (STEM) study within a linguistically diverse school district in California. Analysis of students' state standardized science test scores indicated that the program helped close gaps in scientific achievement between at-risk learners (i.e., English learners, Hispanics, and free/reduced-lunch recipients) and their counterparts. Teacher and student interviews and classroom observations suggested that computer-supported visual representations and interactions supported diverse learners' scientific understanding and inquiry and enabled more individualized and differentiated instruction. Finally, interviews revealed that the program had a positive impact on students' motivation in science and on their interest in pursuing science-related careers. This study suggests that technology-facilitated science instruction is beneficial for improving at-risk students' science achievement, scaffolding students' scientific understanding, and strengthening students' motivation to pursue STEM-related careers.

Becoming a scientist: A qualitative study of the educational experience of undergraduates working in an American and a Brazilian research laboratory

NASA Astrophysics Data System (ADS)

Pascoa, Maria Beatriz Amorim

Because the production of scientific and technological innovations has been at the center of debates for economic growth, scientists are recognized as important actors in the current global market. In this study, I will examine the undergraduate education of future scientists by focusing on students working in research projects of faculty members. This research activity has been promoted by American and Brazilian public agencies as an attempt to attract more college students to scientific careers as well as to improve their future performance in science. Evaluations of these programs have focused on important quantitative indicators focusing mainly on the amount of students that later choose to pursue scientific careers. However, these studies fail to address important educational aspects of undergraduates' experience. In this research, I explore the educational processes taking place as students are introduced to the making of science in order to understand how and what they are learning. Three bodies of literature illuminates the formulation and the analysis of the research questions: (1) theories of globalization situate the education of scientists within the dynamics of a broader social, economic, cultural, and historical framework; (2) the critical pedagogy of Paulo Freire is the basis for the understanding of the pedagogical processes shaping undergraduate students' experiences within the research site; (3) Critical and Cultural Studies of Science and Technology illuminate the analysis of the complex interactions and practices constructed within the laboratory. In order to understand the educational processes shaping the experiences of undergraduate students engaged in research activities, I conducted a qualitative investigation based on participant-observation and in-depth interviews in an American and a Brazilian laboratories. The two sites constituted insightful case studies that illuminated the understanding of inquires about the training of students in science. In addition, the study of two countries enriched the research inquiry, adding to the findings reflections on the ways differences in national contexts affects scientific training and scientific practices. Mainly, this qualitative research of students in laboratories offers some concrete recommendations and illuminating reflections for science educators, science policy makers, and for those working in the understanding of science epistemologies.

E-Labs - Learning with Authentic Data

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bardeen, Marjorie G.; Wayne, Mitchell

the success teachers have had providing an opportunity for students to: • Organize and conduct authentic research. • Experience the environment of scientific collaborations. • Possibly make real contributions to a burgeoning scientific field. We've created projects that are problem-based, student driven and technology dependent. Students reach beyond classroom walls to explore data with other students and experts and share results, publishing original work to a worldwide audience. Students can discover and extend the research of other students, modeling the processes of modern, large-scale research projects. From start to finish e-Labs are student-led, teacher-guided projects. Students need only a Webmore » browser to access computing techniques employed by professional researchers. A Project Map with milestones allows students to set the research plan rather than follow a step-by-step process common in other online projects. Most importantly, e-Labs build the learning experience around the students' own questions and let them use the very tools that scientists use. Students contribute to and access shared data, most derived from professional research databases. They use common analysis tools, store their work and use metadata to discover, replicate and confirm the research of others. This is where real scientific collaboration begins. Using online tools, students correspond with other research groups, post comments and questions, prepare summary reports, and in general participate in the part of scientific research that is often left out of classroom experiments. Teaching tools such as student and teacher logbooks, pre- and post-tests and an assessment rubric aligned with learner outcomes help teachers guide student work. Constraints on interface designs and administrative tools such as registration databases give teachers the "one-stop-shopping" they seek for multiple e-Labs. Teaching and administrative tools also allow us to track usage and assess the impact on student learning.« less

The QuarkNet Collaboration has forged nontraditional relationships among particle physicists, high school teachers and their students. QuarkNet centers are located at 50 + universities and labs across the U.S. and Puerto Rico. We provide professional development for teachers and create opportunities for teachers and students to engage in particle physics data investigations and join research teams. Students develop scientific knowledge and habits of mind by working alongside scientists to make sense of the world using authentic experimental data. Our program is based a classroom vision where teaching strategies emulate closely the way scientists build knowledge through inquiry. We look at how student engagement in research and masterclasses develops an understanding about the process of scientific discovery and science using current scientific data. We also look at ways and to what extent teachers provide scientific discovery and science practices for students and how QuarkNet contributes to the professionalism of participating teachers. Also, we describe success factors that enhance local center programs and describe important benefits of the program that flow to university faculty.

Predictors of scientific understanding of middle school students

NASA Astrophysics Data System (ADS)

Strate, Joshua Matthew

The purpose of this study was to determine if middle school student scientific understanding could be predicted by the variables: standardized 5th grade score in science, standardized 5th grade score in mathematics, standardized 5th grade score in reading, student attitude towards science, socioeconomic status, gender, and ethnicity. The areas of the comprehensive literature review were trends in science learning and teaching, research in the K-12 science education arena, what factors have influenced K-12 science education, scientific understanding, what research has been done on K-12 scientific understanding, and what factors have influenced science understanding in the K-12 arenas. Based on the results of the literature review, the researcher of this study examined a sample of middle school 8th grade students. An Attitude Towards Science Survey (SATS) Simpson & Oliver (1990) and a Survey of Scientific Understandings (Klapper, DeLucia, & Trent, 1993) were administered to these 116 middle school 8th grade students drawn from a total population of 1109 who attend this middle school in a typical county in Florida during the 2010- 2011 school year. Multiple linear regression analysis was used to test each sub-hypothesis and to provide a model that attempted to predict student scientific understanding. Seven null sub-hypotheses were formed to determine if there were significant relationships between student scientific understanding and the abovementioned variables. The results of the tests of the seven null sub-hypotheses showed that the sub-hypothesis that involved socioeconomic status was rejected, which indicated that the socioeconomic status of a family does influence the level of scientific understanding of a student. Low SES students performed lower on the scientific understanding survey, on average, than high SES students. This study can be a source of information for teachers in low-income schools by recognizing potential areas of concern for low-income students in their science classrooms. The study is also a guide for administrators in developing science curriculum that is designed to remediate critical science content. Recommendations, further research, and implications for stakeholders in the science education process are then identified in order to focus on the concerns that these stakeholders need to address through a needs assessment.

Immediate dissemination of student discoveries to a model organism database enhances classroom-based research experiences.

Wiley, Emily A; Stover, Nicholas A

2014-01-01

Use of inquiry-based research modules in the classroom has soared over recent years, largely in response to national calls for teaching that provides experience with scientific processes and methodologies. To increase the visibility of in-class studies among interested researchers and to strengthen their impact on student learning, we have extended the typical model of inquiry-based labs to include a means for targeted dissemination of student-generated discoveries. This initiative required: 1) creating a set of research-based lab activities with the potential to yield results that a particular scientific community would find useful and 2) developing a means for immediate sharing of student-generated results. Working toward these goals, we designed guides for course-based research aimed to fulfill the need for functional annotation of the Tetrahymena thermophila genome, and developed an interactive Web database that links directly to the official Tetrahymena Genome Database for immediate, targeted dissemination of student discoveries. This combination of research via the course modules and the opportunity for students to immediately "publish" their novel results on a Web database actively used by outside scientists culminated in a motivational tool that enhanced students' efforts to engage the scientific process and pursue additional research opportunities beyond the course.

Yeo, Jennifer; Gilbert, John K.

2014-07-01

Studies analyzing explanations that have been constructed by science students have found that they were generally weak and lack necessary features. The goal of this study was to establish the competencies that one needs to construct a scientific explanation. Scientific explanations can be looked at in three ways, in terms of their function, form and level, as being essentially sign-making processes. Taking a case study approach and using Lemke's multimodal framework, we analyzed the scientific explanation of an electromagnetic induction phenomenon constructed by one high school student. We found that such a construction involves the complex coordination of different types of signs, not only to represent the entities in the phenomenon, but also to support thinking and reasoning about it at abstract levels. Scientific conventions and rules, and everyday material and social tools were found to be crucial in shifting from one level of abstraction to another. The findings highlight the importance of developing the skillful use of schemes of scientific representation by students and familiarizing them with commonly encountered contexts.

This poster presents the preliminary results from an experimental approach to teaching first-year writing using the scientific method as an organizing theme. The approach presumes a close connection between the classical scientific method: observing, hypothesis forming, hypothesis testing, and generalizing from the results of the testing, and the writing process: inventing and prewriting, drafting, and revising. The project has four goals: 1. To introduce students to the relations between scientific method, academic inquiry, and the writing process; 2. To help students see that academic inquiry, the work of generating, testing, and validating knowledge and then applying that knowledge in real contexts, is actually a hybrid form of the scientific method; 3. To encourage students to connect the work they are doing in the writing classroom with the work they are doing in other classes so they can transfer the skills learned in one context to the other; and 4. To cause students who have previously been alienated by science and science teaching to reconsider their attitudes, and to see the powerful influence of science and scientific thinking in our world. In short, we are teaching science literacy in a humanities classroom. The materials we use include science-based reading and the kinds of writing typically required in science classes. The poster presents the basic premises of the project, samples of class materials, and preliminary results of a controlled pre- and post-test of student attitudes toward science and writing, analyzed especially according to gender and minority status. We also present insights by participating instructors including a female graduate teaching assistant who had been trained as a scientist and a male who had not.

Patterns in Nature Forming Patterns in Minds: An Evaluation of an Introductory Physics Unit

NASA Astrophysics Data System (ADS)

Sheaffer, Christopher Ryan

Educators are increasingly focused on the process over the content. In science especially, teachers want students to understand the nature of science and investigation. The emergence of scientific inquiry and engineering design teaching methods have led to the development of new teaching and evaluation methods that concentrate on steps in a process rather than facts in a topic. Research supports the notion that an explicit focus on the scientific process can lead to student science knowledge gains. In response to new research and standards many teachers have been developing teaching methods that seem to work well in their classrooms, but lack the time and resources to test them in other classroom environments. A high school Physics teacher (Bradford Hill) has developed a unit called Patterns in Nature (PIN) with objectives relating mathematical modeling to the scientific process. Designed for use in his large public school classroom, the unit was taken and used in a charter school with small classes. This study looks at specifically whether or not the PIN unit effectively teaches students how to graph the data they gather and fit an appropriate mathematical pattern, using that model to predict future measurements. Additionally, the study looks at the students' knowledge and views about the nature of science and the process of scientific investigation as it is affected by the PIN unit. Findings show that students are able to identify and apply patterns to data, but have difficulties explaining the meaning of the math. Students' show increases in their knowledge of the process of science, and the majority develop positive views about science in general. A major goal of this study is to place this unit in the cyclical process of Design-Based Research and allow for Pattern in Nature's continuous improvement, development and evaluation. Design-Based Research (DBR) is an approach that can be applied to the implementation and evaluation of classroom materials. This method incorporates the complexities of different contexts and changing treatments into the research methods and analysis. From the use of DBR teachers can understand more about how the designed materials affect the students. Others may be able to use the development and analysis of PIN study as a guide to look at similar aspects of science units developed elsewhere.

A case-study of a socio-scientific issues curricular and pedagogical intervention in an undergraduate microbiology course: A focus on informal reasoning

NASA Astrophysics Data System (ADS)

Schalk, Kelly A.

The purpose of this investigation was to measure specific ways a student interest SSI-based curricular and pedagogical affects undergraduates' ability informally reason. The delimited components of informal reasoning measured were undergraduates' Nature of Science conceptualizations and ability to evaluate scientific information. The socio-scientific issues (SSI) theoretical framework used in this case-study has been advocated as a means for improving students' functional scientific literacy. This investigation focused on the laboratory component of an undergraduate microbiology course in spring 2008. There were 26 participants. The instruments used in this study included: (1) Individual and Group research projects, (2) journals, (3) laboratory write-ups, (4) a laboratory quiz, (5) anonymous evaluations, and (6) a pre/post article exercise. All instruments yielded qualitative data, which were coded using the qualitative software NVivo7. Data analyses were subjected to instrumental triangulation, inter-rater reliability, and member-checking. It was determined that undergraduates' epistemological knowledge of scientific discovery, processes, and justification matured in response to the intervention. Specifically, students realized: (1) differences between facts, theories, and opinions; (2) testable questions are not definitively proven; (3) there is no stepwise scientific process; and (4) lack of data weakens a claim. It was determined that this knowledge influenced participants' beliefs and ability to informally reason. For instance, students exhibited more critical evaluations of scientific information. It was also found that undergraduates' prior opinions had changed over the semester. Further, the student interest aspect of this framework engaged learners by offering participants several opportunities to influentially examine microbiology issues that affected their life. The investigation provided empirically based insights into the ways undergraduates' interest and functional scientific literacy can be promoted. The investigation advanced what was known about using SSI-based frameworks to the post-secondary learner context. Outstanding questions remain for investigation. For example, is this type of student interest SSI-based intervention broadly applicable (i.e., in other science disciplines and grade levels)? And, what challenges would teachers in diverse contexts encounter when implementing a SSI-based theoretical framework?

Novosibirsk State University (NSU) is different from other universities in Russia. The campus is located in Academgorodok, a unique place where more than 30 scientific institutes and Academpark (Technopark) are located. The students are involved in scientific research from the third year of their study (some try to work part-time in scientific institutions even from their first year). All the university professors are highly-qualified scientists working full-time in scientific institutions. Geology and Geophysics Department (GGD) of NSU is currently reforming the education system and policy. The reform involves the following steps: 1. New scientific programs and courses on modern science have been introduced; the priority should be given to courses in English, as the international language. 2. A special annual conference for students and young scientists was organized in August 2013 in Shira (a place where GGD students have their field trips). 3. International scientists are invited to give seminars and teach on a regular basis. 4. International students are welcomed to study at GGD NSU. 5. GGD stuff is creating a new scientific laboratory within the university. All the above-mentioned steps should ';launch' GGD NSU into a new ';orbit': improve the study process and help the university to be integrated into the world's community.

Argumentation is one factor that can help improve critical thinking skills. Arguing means to defend statements with the various data, denials, evidence, and reinforcement that support the statement. The research aimed to capture the quality of argument skills by students in grade 12 high school students and in postgraduate student on social-scientific issues of cancer. Both group subjects are not in the same school or institution, chosen purposively with the subject of 39 high school students of grade 12 in one district of West Java and 13 students of Biology education postgraduate in one of University in West Java - Indonesia. The results of the quality structure of arguments in both subject groups show the same pattern, which is claim - warrant - and ground, with the quality of counterclaim aspects on the postgraduate students look better than grade 12 students. This provides an illustration that the ability in argumentation between students and teachers in the socio-scientific issue of cancer should be evaluate so that the learning process would be more refined in schools.

Living in a material world: Development and evaluation of a new materials science course for non-science majors

Brust, Gregory John

This study was designed to discover if there is a difference in the scientific attitudes and process skills between a group of students who were instructed with Living in a Material World and groups of students in non-science majors sections of introductory biology, chemistry, and geology courses at the University of Southern Mississippi (USM). Each of the four courses utilized different instructional techniques. Students' scientific attitudes were measured with the Scientific Attitudes Inventory (SAI II) and their knowledge of science process skills were measured with the Test of Integrated Process Skills (TIPS II). The Group Assessment of Logical Thinking (GALT) was also administered to determine if the cognitive levels of students are comparable. A series of four questionnaires called Qualitative Course Assessments (QCA) were also administered to students in the experimental course to evaluate subtle changes in their understanding of the nature and processes of science and attitudes towards science. Student responses to the QCA questionnaires were triangulated with results of the qualitative instruments, and students' work on the final project. Results of the GALT found a significant difference in the cognitive levels of students in the experimental course (PSC 190) and in one of the control group, the introductory biology (BSC 107). Results of the SAI II and the TIPS II found no significant difference between the experimental group and the control groups. Qualitative analyses of students' responses to selected questions from the TIPS II, selected items on the SAI II, QCA questionnaires, and Materials that Fly project reports demonstrate an improvement in the understanding of the nature and processes of science and a change to positive attitude toward science of students in the experimental group. Students indicated that hands-on, inquiry-based labs and performance assessment were the most effective methods for their learning. These results indicate that science courses for non-science majors should focus on connections to students' daily lives while utilizing an STS curriculum and inquiry-based activities. Future research could focus on long term effects of this type of course as well as the effectiveness of these teaching methods for science majors.

A Study area in physics learning is purposeful on the effects of various types of learning interventions to help students construct the basic of scientific conception about physics. Microscopic Virtual Media (MVM) are applications for physics learning to support powerful modelling microscopic involving physics concepts and processes. In this study groups (experimental) of 18±20 years old, students were studied to determine the role of MVM in the development of functional understanding of the concepts of thermal expansion in heat transfer. The experimental group used MVM in learning process. The results show that students who learned with virtual media exhibited significantly higher scores in the research tasks. Our findings proved that the MVM may be used as an alternative instructional tool, in order to help students to confront and constructed their basic of scientific conception and developed their understanding.

Merits of Undergraduate and High School Research

When it comes to sports, everyone gets it; you have to play to really understand, experience, and learn what the game is all about. It would be ludicrous to teach basketball by practicing basketball fundamentals in the gym (layups, free throws, jump shots, dribbling, defense), reading about and attending professional basketball games, but never playing in a game. As important as classes and teaching laboratories may be in science education, there is simply no substitute for active engagement in scientific research to show students what science is all about and, perhaps even more importantly, to inspire and motivate them to become scientists or at least appreciate science. It is a widely held misconception that a student cannot really do meaningful, publishable scientific research until he/she is in graduate school. In actual fact, college undergraduates and even high school students can make original and significant scientific research contributions. Astronomical research, in particular, is very well suited to engage the beginning high school or college undergraduate researcher. The night sky’s inherent accessibility and also its inherent grandeur are natural draws for the curious student’s mind. And much can be learned and discovered using small telescopes. In sports, joining a team is a key aspect of the sports experience. Similarly in science, joining a research team and thereby entering a “community of scientific practice” is fundamental and transformational. As important as working with equipment and acquiring data happen to be in scientific research, this is only the beginning of the research process. Student researchers of all ages—particularly high school students and college undergraduates—have much to gain by giving presentations on their research, writing up their results for publication, and going through the peer review process. But this only works if the student researchers are imbedded within the community of practice.

The ability of scientific argumentation is an essential factor that must be mastered by physics teacher candidate as a requirement in explaining good and accurate scientific concepts. In the process of arguing, students develop explanations or persuade colleagues to support their hypotheses, express doubts, ask questions, relate alternative answers, and confirm what is unknown to develop the ability to provide rational and scientific explanations. The design of this research is descriptive qualitative with the subject of research is 20 undergraduate students of Physics Education Department in Surabaya. The research instrument consists of four casuistic questions related to the concept of kinematics. The argumentation pattern of physics teacher candidate is coded using Toulmin's argumentation pattern. The results show that the student’s ability in providing scientific argument is at the level of providing claims with the support of a weak warrant. The students are not able to provide excellent rebuttals. In each case given, the student can give a good claim statement in answering the questions. However, the concept used to support the claim is not correct. This case causes the warrant used to support the claim is weak. Students also do not analyse other facts that affect the system. Students have not reached a higher level because the understanding of physics is not deep enough.

Due to immense technological and economic developments, human activities producing greenhouse gases, destructing ecosystems, changing landscapes and societies are influencing the world to such a degree, that the environment and human well-being are significantly affected. This results in a need to educate citizens towards a scientific understanding of complex socio-environmental systems. The OECD programme for international student assessment (PISA - http://www.pisa.oecd.org) investigated in detail the science competencies of 15-year-old students in 2006. The report documented that teenagers in OECD countries are mostly well aware of environmental issues but often know little about their causes or options to tackle these challenges in the future. For the integration of science with school learning and involving young people actively into scientific research Sparkling Science projects are funded by the Federal Ministry of Science and Research in Austria. Within the Sparkling Science Project "FlussAu:WOW!" (http://www.sparklingscience.at/de/projekte/574-flussau-wow-/) scientists work together with 15 to 18-year-old students of two Austrian High Schools over two years to assess the functions and processes in near natural and anthropogenically changed river floodplains. Within the first year of collaboration students, teachers and scientists elaborated on abiotic, biotic and spatial indicators for assessing and evaluating the ecological functionality of riverine systems. After a theoretical introduction students formulated research questions, hypotheses and planned and conducted field work in two different floodplain areas in Lower Austria. From the second year on, students are going to develop qualitative models on processes in river floodplain systems by means of the learning software "DynaLearn". The "DynaLearn" software is an engaging, interactive, hierarchically structured learning environment that was developed within the EU-FP7 project "DynaLearn" (http://www.dynalearn.eu) to capture and simulate qualitative causal relationships across disciplines and scales. In "FlussAu:WOW!" students work in groups of two and are guided to think about processes and interactions of hydrological, biological, ecological, spatial and societal elements within a river catchment. They can develop their own causal models and scenarios (e.g., hydrological changes in river run off due to landscape changes in the upper catchment) but also can compare their conceptions to expert models that will be provided. As main benefit, the models help students to reflect their own conceptions in the light of scientific knowledge but also scientists learn about the viewpoints and conceptions young students might have from their environment. The comparison of pre- and post-tests conducted within the "FlussAu:WOW!" project showed that students increased significantly their factual knowledge on different processes in river systems during the first year. Questions regarding functions, processes and elements of riverine landscapes were answered more extensively. This can be ascribed to students` active involvement in scientific research. However, the causal understanding still showed room for improvement, which will be tackled during the next qualitative modelling exercises. Summarizing, involvement of secondary school students in research projects is an effective means to increase scientific literacy when active participation with reflective integration are combined. Ensuring that young people are proficient in system knowledge and understanding makes it more likely that environmental and sustainable considerations are soundly addressed in the future.

Recent studies question the effectiveness of a traditional university curriculum in helping students improve their critical thinking and scientific literacy. We developed an introductory, general education (gen ed) science course to overcome both deficiencies. The course, titled Foundations of Science, differs from most gen ed science offerings in that it is interdisciplinary; emphasizes the nature of science along with, rather than primarily, the findings of science; incorporates case studies, such as the vaccine-autism controversy; teaches the basics of argumentation and logical fallacies; contrasts science with pseudoscience; and addresses psychological factors that might otherwise lead students to reject scientific ideas they find uncomfortable. Using a pretest versus posttest design, we show that students who completed the experimental course significantly improved their critical-thinking skills and were more willing to engage scientific theories the general public finds controversial (e.g., evolution), while students who completed a traditional gen ed science course did not. Our results demonstrate that a gen ed science course emphasizing the process and application of science rather than just scientific facts can lead to improved critical thinking and scientific literacy.

Exploring hypothetical learning progressions for the chemistry of nitrogen and nuclear processes

NASA Astrophysics Data System (ADS)

Henry, Deborah McKern

Chemistry is a bridge that connects a number of scientific disciplines. High school students should be able to determine whether scientific information is accurate, how chemistry applies to daily life, and the mechanism by which systems operate (NRC, 2012). This research focuses on describing hypothetical learning progressions for student understanding of the chemical reactions of nitrogen and nuclear processes and examines whether there is consistency in scientific reasoning between these two distinct conceptual areas. The constant comparative method was used to analyze the written products of students including homework, formative and summative tests, laboratory notebooks, reflective journals, written presentations, and discussion board contributions via Edmodo (an online program). The ten participants were 15 and 16 year old students enrolled in a general high school chemistry course. Instruction took place over a ten week period. The learning progression levels ranged from 0 to 4 and were described as missing, novice, intermediate, proficient, and expert. The results were compared to the standards set by the NRC with a lower anchor (expectations for grade 8) and upper anchor (expectations for grade 12). The results indicate that, on average, students were able to reach an intermediate level of understanding for these concepts.

Incorporating inquiry and the process of science into introductory astronomy labs at the George Washington University

NASA Astrophysics Data System (ADS)

Cobb, Bethany E.

2018-01-01

Since 2013, the Physics Department at GWU has used student-centered active learning in the introductory astronomy course “Introduction to the Cosmos.” Class time is spent in groups on questions, math problems, and hands-on activities, with multiple instructors circulating to answer questions and engage with the students. The students have responded positively to this active-learning. Unfortunately, in transitioning to active-learning there was no time to rewrite the labs. Very quickly, the contrast between the dynamic classroom and the traditional labs became apparent. The labs were almost uniformly “cookie-cutter” in that the procedure and analysis were specified step-by-step and there was just one right answer. Students rightly criticized the labs for lacking a clear purpose and including busy-work. Furthermore, this class fulfills the GWU scientific reasoning general education requirement and thus includes learning objectives related to understanding the scientific method, testing hypotheses with data, and considering uncertainty – but the traditional labs did not require these skills. I set out to rejuvenate the lab sequence by writing new inquiry labs based on both topic-specific and scientific reasoning learning objectives. While inquiry labs can be challenging for the students, as they require active thinking and creativity, these labs engage the students more thoroughly in the scientific process. In these new labs, whenever possible, I include real astronomical data and ask the students to use digital tools (SDSS SkyServer, SOHO archive) as if they are real astronomers. To allow students to easily plot, manipulate and analyze data, I built “smart” Excel files using formulas, dropdown menus and macros. The labs are now much more authentic and thought-provoking. Whenever possible, students independently develop questions, hypotheses, and procedures and the scientific method is “scaffolded” over the semester by providing more guidance in the early labs and more independence later on. Finally, in every lab, students must identify and reflect on sources of error. These labs are more challenging for the instructors to run and to grade, but they are much more satisfying when it comes to student learning.

Melding Research on the Navajo Volcanic Field into Undergraduate Curriculum to Promote Scientific Literacy

NASA Astrophysics Data System (ADS)

Gonzales, D. A.

2011-12-01

This presentation highlights the curricular design and preliminary outcomes of undergraduate research in the Department of Geosciences at Fort Lewis College (FLC), supported by an NSF-RUI project on the Navajo volcanic field (NVF). A prime impact of this project was to support the education and career development of undergraduate students by further developing basic knowledge and skills in the context of authentic inquiry on petrologic-based research topics. Integrating research into the curriculum promoted scientific habits of mind by engaging students as "active agents" in discovery, and the creative development and testing of ideas. It also gave students a sense of ownership in the scientific process and knowledge construction. The initial phase of this project was conducted in Igneous Petrology at FLC in 2010. Eleven students were enrolled in this course which allowed them to work as a team in collaboration with the PI, and engage in all aspects of research to further develop and hone their skills in scientific inquiry. This course involved a small component of traditional lecture in which selected topics were discussed to provide students with a foundation to understand magmatic processes. This was complemented by a comprehensive review of the literature in which students read and discussed a spectrum of articles on Tertiary magmatism in the western United States and the NVF. Invited lectures by leading-scientists in geology provided opportunities for discussions and interaction with professional geologists. All of the students in the class engaged in the active collection of petrologic data in the field and laboratory sessions, and were introduced to the use of state-of-the art analytical tools as part of their experiences. Four students were recruited from the course to design, develop, and conduct long-term research projects on selected petrologic topics in the NVF. This research allowed these students to engage in the "messy" process of testing existing hypotheses on NVF magmatism, and developing new ideas and interpretations. The combined outcomes of these research projects provided a collection of original data which have made important contributions to our understanding of the history of the NVF. All student projects served to fulfill a mandatory senior-thesis research project and the students were required to attend professional meetings to present their results. Dissemination of the outcomes of student research into the broader geologic community allowed the students to interact as peers in their field of study. The insight and values that these future geoscientists gained from research experiences early in their education and careers is critical to their professional development. This process infused the students with a greater understanding of science methods and activities. The integration of classroom studies with applied research has a positive impact on the scientific awareness of budding geoscientists which stand to impact the future decisions of society and communities. Data collected on student perspectives document the successful outcomes of this combined research-education project.

Brownell, Sara E; Price, Jordan V; Steinman, Lawrence

2013-03-01

Most scientists agree that comprehension of primary scientific papers and communication of scientific concepts are two of the most important skills that we can teach, but few undergraduate biology courses make these explicit course goals. We designed an undergraduate neuroimmunology course that uses a writing-intensive format. Using a mixture of primary literature, writing assignments directed toward a layperson and scientist audience, and in-class discussions, we aimed to improve the ability of students to 1) comprehend primary scientific papers, 2) communicate science to a scientific audience, and 3) communicate science to a layperson audience. We offered the course for three consecutive years and evaluated its impact on student perception and confidence using a combination of pre- and postcourse survey questions and coded open-ended responses. Students showed gains in both the perception of their understanding of primary scientific papers and of their abilities to communicate science to scientific and layperson audiences. These results indicate that this unique format can teach both communication skills and basic science to undergraduate biology students. We urge others to adopt a similar format for undergraduate biology courses to teach process skills in addition to content, thus broadening and strengthening the impact of undergraduate courses.

Fostering Students’ and Teachers’ Understanding of the Nature of Science: Where We Need the Broadest of Broader Impacts

Laursen, S. L.; Dauber, R.; Molnar, P. H.; Smith, L. K.

2009-12-01

Making wise decisions about daunting societal and environmental problems requires understanding of both scientific concepts and the limits of scientific knowledge. While K-12 school standards now include topics on scientific inquiry and the nature of science, few science teachers have personal knowledge of these ideas through conducting science research first-hand. In their own education, most have experienced primarily fact-packed lecture courses rather than deep engagement with gathering, interpreting and communicating about scientific evidence. Teachers are thus at a disadvantage in teaching about the nature of science. Moreover, few curriculum materials directly address these ideas. Instead, instructors at all levels tend to rely on students gleaning ideas from their lab work, without ever making them explicit. The result is a poor understanding of the nature of science among many students and citizens. Thus the nature of science is an important and fruitful area for “broader impacts” efforts by NSF-funded projects across the entire spectrum of science. To address this gap, we have created a 20-minute educational documentary film focused on the nature and processes of science. The film is a broader impacts effort for a large, NSF-funded, multidisciplinary, collaborative research project to study the uplift of the Tibetan plateau and its impact on atmospheric and climate processes. The film, Upward and Outward: Scientific Inquiry on the Tibetan Plateau, focuses on the process of science, as seen through the lens of a specific project. Viewers follow an international team of scientists as they work in the laboratory and in the field, build new instruments and computer models, travel to exotic locales, argue about their findings, and enjoy collaboration and conversation. By gaining an insider’s glimpse into both the intellectual process of scientific inquiry and the everyday social and professional activities of science, students learn how science is a human process for building knowledge, not just a body of fact. While originally targeted to students in grades 8-12, the film has also proven effective with undergraduates in introductory science courses, and with teachers in professional development courses. The 20-minute length ensures that the film can be readily screened and discussed within a single class session, and teachers are supported with suggested pre/post writing prompts, discussion questions, teaching tips, and background materials on the film's scientific content. The presentation will describe the making of the film, its relationship to the scientific project, its use with students and teachers, and some data on their responses. We will show a short clip and make copies of the DVD available to educators and professional developers who attend the session. More information about the film, a short clip, and supporting information for educators can be found at our web site.

How People Reason: A Grounded Theory Study of Scientific Reasoning about Global Climate Change

NASA Astrophysics Data System (ADS)

Liu, Shiyu

Scientific reasoning is crucial in both scientific inquiry and everyday life. While the majority of researchers have studied "how people reason" by focusing on their cognitive processes, factors related to the underpinnings of scientific reasoning are still under-researched. The present study aimed to develop a grounded theory that captures not only the cognitive processes during reasoning but also their underpinnings. In particular, the grounded theory and phenomenographic methodologies were integrated to explore how undergraduate students reason about competing theories and evidence on global climate change. Twenty-six undergraduate students were recruited through theoretical sampling. Constant comparative analysis of responses from interviews and written assessments revealed that participants were mostly drawn to the surface features when reasoning about evidence. While prior knowledge might not directly contribute to participants' performance on evidence evaluation, it affected their level of engagement when reading and evaluating competing arguments on climate issues. More importantly, even though all participants acknowledged the relative correctness of multiple perspectives, they predominantly favored arguments that supported their own beliefs with weak scientific reasoning about the opposing arguments. Additionally, factors such as personal interests, religious beliefs, and reading capacity were also found to have bearings on the way participants evaluated evidence and arguments. In all, this work contributes to the current endeavors in exploring the nature of scientific reasoning. Taking a holistic perspective, it provides an in-depth discussion of factors that may affect or relate to scientific reasoning processes. Furthermore, in comparison with traditional methods used in the literature, the methodological approach employed in this work brought an innovative insight into the investigation of scientific reasoning. Last but not least, this research may help initiate further discussion regarding how to bridge cognitive research with science education to promote student learning of complex scientific issues such as global climate change.

Immediate Dissemination of Student Discoveries to a Model Organism Database Enhances Classroom-Based Research Experiences

2014-01-01

Use of inquiry-based research modules in the classroom has soared over recent years, largely in response to national calls for teaching that provides experience with scientific processes and methodologies. To increase the visibility of in-class studies among interested researchers and to strengthen their impact on student learning, we have extended the typical model of inquiry-based labs to include a means for targeted dissemination of student-generated discoveries. This initiative required: 1) creating a set of research-based lab activities with the potential to yield results that a particular scientific community would find useful and 2) developing a means for immediate sharing of student-generated results. Working toward these goals, we designed guides for course-based research aimed to fulfill the need for functional annotation of the Tetrahymena thermophila genome, and developed an interactive Web database that links directly to the official Tetrahymena Genome Database for immediate, targeted dissemination of student discoveries. This combination of research via the course modules and the opportunity for students to immediately “publish” their novel results on a Web database actively used by outside scientists culminated in a motivational tool that enhanced students’ efforts to engage the scientific process and pursue additional research opportunities beyond the course.

Can we really make a difference? Exploring pre-service teachers' experience with socio-scientific issues aiming for democratic participation in science

NASA Astrophysics Data System (ADS)

Cook, Kristin Leigh

Responding to calls for an empirical glimpse into a socioscientific issues (SSI)-based curriculum that aims to promote democratic participation, enhance students' connections to science, and empower students for the betterment of society (Dos Santos, 2008; Sadler, Barab, & Scott, 2007; Tal & Kedmi, 2006; Fusco & Barton, 2001; Hodson, 2003), this critical case study of 24 pre-service teachers (PSTs) enrolled in a scientific inquiry course offers curricular suggestions to empower learners to connect with the dynamic and socially-mediated process of science. In effect, incorporating nature of science-focused and place-based inquiry into a collaboration between PSTs and scientists were essential elements in enhancing students' connections to and feelings of inclusion in SSI. Propelled beyond a deficit model of public participation in science, the PSTs did indeed experience a public debate model and in some cases a knowledge production model in their collaborative efforts with scientists (Callon, 1999; Pouliot, 2009). While all of the PSTs engaged in rich discussion of their perspectives with scientists to enhance the investigation of their inquiry, some experienced a redistribution of the roles of participation in the production of scientific knowledge that was integrated into the scientists' decision-making processes. The materialization of these models depended on the structures of the student-scientists collaboration and the ways in which these malleable structures were flexed and negotiated. In effect, this study contributes to the literature on the potentials of SSI by providing an example of an educational approach that engages learners in a community practice as active participants in decision-making processes regarding socio-scientific issues, as well as focuses on empowering learners to be involved in the generation of scientific knowledge that contributes to their community.

Preparing for Science at Sea - a Chief Scientists Training Cruise on Board the RV Sikuliaq

Coakley, B.; Pockalny, R. A.

2017-12-01

As part of their education, marine geology and geophysics students spend time at sea, collecting, processing and interpreting data to earn their degrees. While this is a critical component of their preparation, it is an incomplete introduction to the process of doing science at sea. Most students are unfamiliar with the proposal process. Many students spend their time at sea performing assigned tasks without responsibility or participation in cruise planning and execution. In December 2016, we conducted a two-week-long, NSF-funded "Chief Scientist Training Cruise" aboard the R/V Sikuliaq designed to complete their introduction to seagoing science by giving the students the opportunity to plan and execute surveys based hypotheses they formulated. The educational process began with applicants responding to a request for proposals (RFP), which provided a framework for the scientific potential of the cruise. This process continued training through two days of workshops and presentations at the Hawai'i Institute of Geophysics. The students used existing data to define hypotheses, plan surveys, and collect/analyze data to test their hypothesis. The survey design was subject to the time constraints imposed by the ship schedule and the physical constraints imposed by the ship's equipment. The training and sea time made it possible to address all of steps of the scientific process, including proposal writing. Once underway, the combination of conducting the planned surveys and attending daily presentations helped familiarize the students with at-sea operations, the equipment on board the RV Sikuliaq, and the process of writing proposals to NSF for sea-going science. Questionnaires conducted prior to the cruise and in the final days before arriving in port document the success of this training program for developing the abilities and confidence in identifying significant scientific problems, preparing proposals to secure funding, and planning and directing ship surveys.

2012-12-01

This article presents a detailed guide for high school through graduate level instructors that leads students to write effective and well-organized scientific papers. Interesting research emerges from the ability to ask questions, define problems, design experiments, analyze and interpret data, and make critical connections. This process is incomplete, unless new results are communicated to others because science fundamentally requires peer review and criticism to validate or discard proposed new knowledge. Thus, a concise and clearly written research paper is a critical step in the scientific process and is important for young researchers as they are mastering how to express scientific concepts and understanding. Moreover, learning to write a research paper provides a tool to improve science literacy as indicated in the National Research Council's National Science Education Standards (1996), and A Framework for K-12 Science Education (2011), the underlying foundation for the Next Generation Science Standards currently being developed. Background information explains the importance of peer review and communicating results, along with details of each critical component, the Abstract, Introduction, Methods, Results, and Discussion. Specific steps essential to helping students write clear and coherent research papers that follow a logical format, use effective communication, and develop scientific inquiry are described.

Brown, James A L

2016-05-06

A pedagogic intervention, in the form of an inquiry-based peer-assisted learning project (as a practical student-led bioinformatics module), was assessed for its ability to increase students' engagement, practical bioinformatic skills and process-specific knowledge. Elements assessed were process-specific knowledge following module completion, qualitative student-based module evaluation and the novelty, scientific validity and quality of written student reports. Bioinformatics is often the starting point for laboratory-based research projects, therefore high importance was placed on allowing students to individually develop and apply processes and methods of scientific research. Students led a bioinformatic inquiry-based project (within a framework of inquiry), discovering, justifying and exploring individually discovered research targets. Detailed assessable reports were produced, displaying data generated and the resources used. Mimicking research settings, undergraduates were divided into small collaborative groups, with distinctive central themes. The module was evaluated by assessing the quality and originality of the students' targets through reports, reflecting students' use and understanding of concepts and tools required to generate their data. Furthermore, evaluation of the bioinformatic module was assessed semi-quantitatively using pre- and post-module quizzes (a non-assessable activity, not contributing to their grade), which incorporated process- and content-specific questions (indicative of their use of the online tools). Qualitative assessment of the teaching intervention was performed using post-module surveys, exploring student satisfaction and other module specific elements. Overall, a positive experience was found, as was a post module increase in correct process-specific answers. In conclusion, an inquiry-based peer-assisted learning module increased students' engagement, practical bioinformatic skills and process-specific knowledge. © 2016 by The International Union of Biochemistry and Molecular Biology, 44:304-313 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

Creating a lab to facilitate high school student engagement in authentic paleoclimate science practices

NASA Astrophysics Data System (ADS)

Maloney, A.; Walsh, E.

2012-12-01

A solid understanding of timescales is crucial for any climate change discussion. This hands-on lab was designed as part of a dual-credit climate change course in which high school students can receive college credit. Using homemade ice cores, students have the opportunity to participate in scientific practices associated with collecting, processing, and interpreting temperature and CO2 data. Exploring millennial-scale cycles in ice core data and extending the CO2 record to the present allows students to discover timescales from an investigators perspective. The Ice Core Lab has been piloted in two high school classrooms and student engagement, and epistemological and conceptual understanding was evaluated using quantitative pre and post assessment surveys. The process of creating this lab involved a partnership between an education assessment professional, high school teachers, and University of Washington professors and graduate students in Oceanography, Earth and Space Sciences, Atmospheric Sciences and the Learning Sciences as part of the NASA Global Climate Change University of Washington in the High School program. This interdisciplinary collaboration led to the inception of the lab and was necessary to ensure that the lesson plan was pedagogically appropriate and scientifically accurate. The lab fits into a unit about natural variability and is paired with additional hands-on activities created by other graduate students that explore short-timescale temperature variations, Milankovitch cycles, isotopes, and other proxies. While the Ice Core Lab is intended to follow units that review the scientific process, global energy budget, and transport, it can be modified to fit any teaching platform.

Examining the development of scientific reasoning in ninth-grade physical science students

NASA Astrophysics Data System (ADS)

Westbrook, Susan L.; Rogers, Laura N.

This study-was designed to test the hypothesis that descriptive learning cycles are neither sufficient to stimulate students to reason at a formal operational level nor to encourage facility with the processes of scientific investigation. A 6-week long, three-investigation unit on simple machines drawn from a ninth-grade physical science curriculum was selected for the study. Students in the course were assigned to one of three instructional groups: descriptive group (DE), question design group (QD), and hypothesis testing group (HT). Each group completed identical exploration and invention activities. Each group participated in qualitatively distinct activities during the expansion phase. The DE students completed the activities outlined in the curriculum (a descriptive learning cycle). The QD group designed and conducted experiments to answer a question posed by the teacher. The HT group generated hypotheses concerning a problem, then designed and conducted experiments to test those hypotheses (a hypothetico-deductive expansion). The effects of the treatments were assessed in a pretest-posttest format using Lawson's Seven Logic-Tasks, the Test of Integrated Process Skills, and Lawson's Revised Classroom Test of Scientific Reasoning. Analyses of the data indicated that the HT group exhibited a significant increase on the Test of Integrated Process Skills and on Task 1 of the Seven Logic Tasks during the 6-week period.

Learning genetic inquiry through the use, revision, and justification of explanatory models

NASA Astrophysics Data System (ADS)

Cartier, Jennifer Lorraine

Central to the process of inquiry in science is the construction and assessment of models that can be used to explain (and in some cases, predict) natural phenomena. This dissertation is a qualitative study of student learning in a high school biology course that was designed to give students opportunities to learn about genetic inquiry in part by providing them with authentic experiences doing inquiry in the discipline. With the aid of a computer program that generates populations of "fruit flies", the students in this class worked in groups structured like scientific communities to build, revise, and defend explanatory models for various inheritance phenomena. Analysis of the ways in which the first cohort of students assessed their inheritance models revealed that all students assessed models based upon empirical fit (data/model match). However, in contrast to the practice of scientists and despite explicit instruction, students did not consistently apply conceptual assessment criteria to their models. That is, they didn't seek consistency between underlying concepts or processes in their models and those of other important genetic models, such as meiosis. This is perhaps in part because they lacked an understanding of models as conceptual rather than physical entities. Subsequently, the genetics curriculum was altered in order to create more opportunities for students to address epistemological issues associated with model assessment throughout the course. The second cohort of students' understanding of models changed over the nine-week period: initially the majority of students equated scientific models with "proof" (generally physical) of "theories"; at the end of the course, most students demonstrated understanding of the conceptual nature of scientific models and the need to justify such knowledge according to both its empirical utility and conceptual consistency. Through model construction and assessment (i.e. scientific inquiry), students were able to come to a rich understanding of both the central concepts of transmission genetics and important epistemological aspects of genetic practice.

Influence of teacher-directed scientific inquiry on students' primal inquiries in two science classrooms

NASA Astrophysics Data System (ADS)

Stone, Brian Andrew

Scientific inquiry is widely used but pervasively misunderstood in elementary classrooms. The use of inquiry is often attached to direct instruction models of teaching, or is even passed as textbook readings or worksheets. Previous literature on scientific inquiry suggests a range or continuum beginning with teacher-directed inquiry on one extreme, which involves a question, process, and outcome that are predetermined by the teacher. On the other end of the continuum is an element of inquiry that is extremely personal and derived from innate curiosity without external constraints. This authentic inquiry is defined by the study as primal inquiry. If inquiry instruction is used in the elementary classroom, it is often manifested as teacher-directed inquiry, but previous research suggests the most interesting, motivating, and lasting content is owned by the individual and exists within the individual's own curiosity, questioning and processes. Therefore, the study examined the impact of teacher-directed inquiry in two elementary fourth grade classrooms on climate-related factors including interest, motivation, engagement, and student-generated inquiry involvement. The study took place at two elementary classrooms in Arizona. Both were observed for ten weeks during science instruction over the course of one semester. Field notes were written with regard for the inquiry process and ownership, along with climate indicators. Student journals were examined for evidence of primal inquiry, and twenty-two students were interviewed between the two classrooms for evidence of low climate-related factors and low inquiry involvement. Data from the three sources were triangulated. The results of this qualitative study include evidence for three propositions, which were derived from previous literature. Strong evidence was provided in support of all three propositions, which suggest an overall negative impact on climate-related factors of interest, motivation, and engagement for students working within a teacher-directed scientific inquiry environment. Very little existed in terms of time, materials, or opportunities for students to explore science using their own questions and processes. Furthermore, as students conformed to a teacher-directed inquiry environment, their own primal inquiries were displaced and undervalued. Ownership belonged to the teacher and precluded primal inquiries in both classrooms.

Using Collaborate Writing Groups in Undergraduate Courses to Improve Scientific Writing Skills and Confidence

NASA Astrophysics Data System (ADS)

Maclachlan, J. C.; Feist, S.

2016-12-01

Communication of primary scientific research is an aspect of undergraduate teaching that rarely researches platforms outside of the classroom. One method to encourage the dissemination of scientific findings to an international audience is the implementation of Collaborative Writing Groups (CWG). This paper will discuss the development, implementation and successful results of two Collaborative Writing Group creating within two different senior undergraduate classes offered at McMaster University in Hamilton, Ontario, Canada through discussion of the implementation of the assignment coupled with challenges and opportunities the process provided. A key to the successful implementation of the CWG is a detailed timeline for the students to follow with achievable goals throughout the process. The eight-week process began with students creating groups and choosing a topic of interest. As groups form it became apparent the diversity of academic skills and interest within the classroom made selecting a research project all group members could agree on difficult. Throughout the course students were given time to not only review their colleagues writing but also have discussions on particularly challenging aspects of their research and help in providing solutions. While the timeline for this project was ambitious it was necessary to allow time for effective feedback on the scientific writing from both the students and the instructional team. Overall this process has produced 11 peer-reviewed undergraduate student written papers within two special editions of the journal Cartographica published by the University of Toronto Press (Maclachlan and Lee, 2015). The papers topics are quite diverse including: the modelling of glacier melt in Iceland; a look into the effects of urban sprawl; and an exploration of the spatial characteristics of dunes in southern Ontario. This encouragement of dissemination to an international audience will create an experience that promotes self-authorship and challenges students to evaluate their knowledge claims and take ownership of their ideas.

What is the role of induction and deduction in reasoning and scientific inquiry?

NASA Astrophysics Data System (ADS)

Lawson, Anton E.

2005-08-01

A long-standing and continuing controversy exists regarding the role of induction and deduction in reasoning and in scientific inquiry. Given the inherent difficulty in reconstructing reasoning patterns based on personal and historical accounts, evidence about the nature of human reasoning in scientific inquiry has been sought from a controlled experiment designed to identify the role played by enumerative induction and deduction in cognition as well as from the relatively new field of neural modeling. Both experimental results and the neurological models imply that induction across a limited set of observations plays no role in task performance and in reasoning. Therefore, support has been obtained for Popper's hypothesis that enumerative induction does not exist as a psychological process. Instead, people appear to process information in terms of increasingly abstract cycles of hypothetico-deductive reasoning. Consequently, science instruction should provide students with opportunities to generate and test increasingly complex and abstract hypotheses and theories in a hypothetico-deductive manner. In this way students can be expected to become increasingly conscious of their underlying hypothetico-deductive thought processes, increasingly skilled in their application, and hence increasingly scientifically literate.

Supporting students' scientific explanations: A case study investigating the synergy focusing on a teacher's practices when providing instruction and using mobile devices

NASA Astrophysics Data System (ADS)

Delen, Ibrahim

Engage students in constructing scientific practices is a critical component of science instruction. Therefore a number of researchers have developed software programs to help students and teachers in this hard task. The Zydeco group, designed a mobile application called Zydeco, which enables students to collect data inside and outside the classroom, and then use the data to create scientific explanations by using claim-evidence-reasoning framework. Previous technologies designed to support scientific explanations focused on how these programs improve students' scientific explanations, but these programs ignored how scientific explanation technologies can support teacher practices. Thus, to increase our knowledge how different scaffolds can work together, this study aimed to portray the synergy between a teacher's instructional practices (part 1) and using supports within a mobile devices (part 2) to support students in constructing explanations. Synergy can be thought of as generic and content-specific scaffolds working together to enable students to accomplish challenging tasks, such as creating explanations that they would not normally be able to do without the scaffolds working together. Providing instruction (part 1) focused on understanding how the teacher scaffolds students' initial understanding of the claim-evidence-reasoning (CER) framework. The second component of examining synergy (part 2: using mobile devices) investigated how this teacher used mobile devices to provide feedback when students created explanations. The synergy between providing instruction and using mobile devices was investigated by analyzing a middle school teacher's practices in two different units (plants and water quality). Next, this study focused on describing how the level of synergy influenced the quality of students' scientific explanations. Finally, I investigated the role of focused teaching intervention sessions to inform teacher in relation to students' performance. In conclusion, findings of this study showed that the decrease in the teacher's support for claims, did not affect the quality of the students' claims. On the other hand, the quality of students' reasoning were linked with the teacher's practices. This suggests that when supporting students' explanations, focusing on components that students find challenging would benefit students' construction of explanations. To achieve synergy in this process, the collaboration between teacher's practices, focused teaching intervention sessions and scaffolds designed to support teachers played a crucial role in aiding students in creating explanations.

Do students with higher self-efficacy exhibit greater and more diverse scientific inquiry skills: An exploratory investigation in "River City", a multi-user virtual environment

NASA Astrophysics Data System (ADS)

Ketelhut, Diane Jass

In this thesis, I conduct an exploratory study to investigate the relationship between students' self-efficacy on entry into authentic scientific activity and the scientific inquiry behaviors they employ while engaged in that process, over time. Scientific inquiry has been a major standard in most science education policy doctrines for the past two decades and is exemplified by activities such as making observations, formulating hypotheses, gathering and analyzing data, and forming conclusions from that data. The self-efficacy literature, however, indicates that self-efficacy levels affect perseverance and engagement. This study investigated the relationship between these two constructs. The study is conducted in a novel setting, using an innovative science curriculum delivered through an interactive computer technology that recorded each student's conversations, movements, and activities while behaving as a practicing scientist in a "virtual world" called River City. River City is a Multi-User Virtual Environment designed to engage students in a collaborative scientific inquiry-based learning experience. As a result, I was able to follow students' moment-by-moment choices of behavior while they were behaving as scientists. I collected data on students' total scientific inquiry behaviors over three visits to River City, as well as the number of sources from which they gathered their scientific data. I analyzed my longitudinal data on the 96 seventh-graders using individual growth modeling. I found that self-efficacy played a role in the number of data-gathering behaviors students engaged in initially, with high self-efficacy students engaging in more data gathering than students with low self-efficacy. However, the impact of student self-efficacy on rate of change in data gathering behavior differed by gender; by the end of the study, student self-efficacy did not impact data gathering. In addition, students' level of self-efficacy did not affect how many different sources from which they chose to gather data. There are indications in my results that novel interventions like a Multi-user Virtual Environment might act as a catalyst for change in student learning. Further research using these techniques may enable a better understanding of the interaction between self-efficacy and scientific inquiry, and eventually science learning outcomes.

Akey, Ann Kosek

2000-10-01

This dissertation investigates the influence of student designed experiments with Fast Plants in an undergraduate agroecology course on the students' conceptual understanding of plant life cycles and on their procedural understanding of scientific experimentation. It also considers students' perspectives on the value of these experiences. Data sources included semi-structured interviews with students and the instructor, a written task, course evaluations, and observations of class meetings. Students came into the course having strong practical experience with plants from their agricultural backgrounds. Students did not always connect aspects of plant biology that they studied in class, particularly respiration and photosynthesis, to plant growth requirements. The instructor was able to bridge the gap between some practical knowledge and textbook knowledge with experiences other than the Fast Plant project. Most students held an incomplete picture of plant reproduction that was complicated by differences between agricultural and scientific vocabulary. There is need for teaching approaches that help students tie together their knowledge of plants into a cohesive framework. Experiences that help students draw on their background knowledge related to plants, and which give students the opportunity to examine and discuss their ideas, may help students make more meaningful connections. The Fast Plant project, a positive experience for most students, was seen by these undergraduate students as being more helpful in learning about scientific experimentation than about plants. The process of designing and carrying out their own experiments gave students insight into experimentation, provoked their curiosity, and resulted in a sense of ownership and accomplishment.

Addressing scientific literacy through content area reading and processes of scientific inquiry: What teachers report

NASA Astrophysics Data System (ADS)

Cooper, Susan J.

The purpose of this study was to interpret the experiences of secondary science teachers in Florida as they address the scientific literacy of their students through teaching content reading strategies and student inquiry skills. Knowledge of the successful integration of content reading and inquiry skills by experienced classroom teachers would be useful to many educators as they plan instruction to achieve challenging state and national standards for reading as well as science. The problem was investigated using grounded theory methodology. Open-ended questions were asked in three focus groups and six individual interviews that included teachers from various Florida school districts. The constant comparative approach was used to analyze the data. Initial codes were collapsed into categories to determine the conceptual relationships among the data. From this, the five core categories were determined to be Influencers, Issues, Perceptions, Class Routines, and Future Needs. These relate to the central phenomenon, Instructional Modifications, because teachers often described pragmatic and philosophical changes in their teaching as they deliberated to meet state standards in both reading and science. Although Florida's secondary science teachers have been asked to incorporate content reading strategies into their science instruction for the past several years, there was limited evidence of using these strategies to further student understanding of scientific processes. Most teachers saw little connection between reading and inquiry, other than the fact that students must know how to read to follow directions in the lab. Scientific literacy, when it was addressed by teachers, was approached mainly through class discussions, not reading. Teachers realized that students cannot learn secondary science content unless they read science text with comprehension; therefore the focus of reading instruction was on learning science content, not scientific literacy or student inquiry. Most of the teachers were actively looking for reading materials and strategies to facilitate student understanding of science concepts, but they did not want to give up limited class time attempting methods that have not been proven to be successful in science classrooms.

Focusing on the Processes of Science Using Inquiry-oriented Astronomy Labs for Learning Astronomy

The U.S. National Science Education Standards provide guidelines for teaching science through inquiry, where students actively develop their understanding of science by combining scientific knowledge with reasoning and thinking skills. Inquiry activities include reading scientific literature, generating hypotheses, designing and carrying out investigations, interpreting data, and formulating conclusions. Inquiry-based instruction emphasizes questions, evidence, and explanation, the essential features of inquiry. We present two projects designed to develop learning materials for laboratory experiences in an undergraduate astronomy course. First, we engage students in inquiry-based learning by using "mini-journal” articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. This mini-journal format more directly reflects and encourages scientific practice. We use this technique in both introductory and upper level courses. The second project develops 3D virtual reality environments to help students interact with scientific constructs, and the use of collaborative learning tools to motivate student activity, deepen understanding and support knowledge building.

Learning in Authentic Earth and Planetary Contexts

A Virtual Field Trip project has been developed in collaboration with NASA Learning Technologies to allow students, internationally, to accompany scientists on a field trip to the Pilbara region of Western Australia to debate the relevance of ancient structures called stromatolites, to the origins of life on Earth and the search for life on Mars. The project was planned with the aim of exposing high school students to `science in the making', including exposure to the ongoing debate and uncertainties involved in scientific research. The development of the project stemmed from both research-based and anecdotal evidence that current science education programs are not providing secondary students with a good understanding of the processes of science. This study seeks to examine the effectiveness of student use of the tools to increase awareness of the processes of science and to evaluate the effectiveness of the tools in terms of student learning. The literature reports that there is a need for learning activities to be conducted within meaningful contexts. The virtual field trip tools create an environment that simulates key elements in the scientific process. Such an approach allows students to learn by doing, to work like scientists and apply their learning in an authentic context.

Scaffolding Student Learning in the Discipline-Specific Knowledge through Contemporary Science Practices: Developing High-School Students' Epidemiologic Reasoning through Data Analysis

NASA Astrophysics Data System (ADS)

Oura, Hiroki

Science is a disciplined practice about knowing puzzling observations and unknown phenomena. Scientific knowledge of the product is applied to develop technological artifacts and solve complex problems in society. Scientific practices are undeniably relevant to our economy, civic activity, and personal lives, and thus public education should help children acquire scientific knowledge and recognize the values in relation to their own lives and civil society. Likewise, developing scientific thinking skills is valuable not only for becoming a scientist, but also for becoming a citizen who is able to critically evaluate everyday information, select and apply only the trustworthy, and make wise judgments in their personal and cultural goals as well as for obtaining jobs that require complex problem solving and creative working in the current knowledge-based economy and rapid-changing world. To develop students' scientific thinking, science instruction should focus not only on scientific knowledge and inquiry processes, but also on its epistemological aspects including the forms of causal explanations and methodological choices along with epistemic aims and values under the social circumstances in focal practices. In this perspective, disciplinary knowledge involves heterogeneous elements including material, cognitive, social, and cultural ones and the formation differs across practices. Without developing such discipline-specific knowledge, students cannot enough deeply engage in scientific "practices" and understand the true values of scientific enterprises. In this interest, this dissertation explores instructional approaches to make student engagement in scientific investigations more authentic or disciplinary. The present dissertation work is comprised of three research questions as stand-alone studies written for separate publication. All of the studies discuss different theoretical aspects related to disciplinary engagement in epidemiologic inquiry and student development in epidemiologic reasoning. The first chapter reviews literature on epistemological instruction and explores theoretical frameworks for epistemically-guided instruction. The second chapter explores methodological strategies to elicit students' disciplinary understanding and demonstrates an approach with a case study in which students engaged in a curriculum unit for an epidemiologic investigation. The last chapter directs the focus into scientific reasoning and demonstrates how the curriculum unit and its scaffolds helped students develop epidemiologic reasoning with a focus on population-based reasoning.

This work presents the educational approach of using total solar eclipse occurrences as a scientific process learning aid. The work reviews the basic scientific aims and experiments included in the observational programs "Total solar eclipse 1999 and 2006" (Stoev, A., Kiskinova, N., Muglova, P. et al. Complex observational programme of the Yuri Gagarin Public Astronomical Observatory and STIL, BAS, Stara Zagora Department for the August 11, 1999 total solar eclipse, in: Total Solar Eclipse 1999 - Observational Programmes and Coordination, Proceedings, Recol, Haskovo, pp. 133-137, 1999a (in Bulgarian); Stoeva, P.V., Stoev, A.D., Kostadinov, I.N. et al. Solar Corona and Atmospheric Effects during the March 29, 2006 Total Solar Eclipse, in: 11th International Science Conference SOLAR-Terrestrial Influences, Sofia, November 24-25, pp. 69-72, 2005). Results from teaching and training the students in the procedures, methods and equipment necessary for the observation of a total solar eclipse (TSE) at the Yuri Gagarin Public Astronomical Observatory (PAO) in Stara Zagora, Bulgaria, as well as the selection process used in determining participation in the different observational teams are discussed. The final stages reveal the special methodology used to investigate the level of "pretensions", the levels of ambition displayed by the students in achieving each independent goal, and the setting of goals in context with their problem solving capabilities and information gathering abilities in the scientific observation process. Results obtained from the observational experiments are interpreted mainly in the following themes: Investigation of the structure of the white-light solar corona and evolution of separate coronal elements during the total phase of the eclipse; Photometry of the white-light solar corona and specific emission lines; Meteorological, actinometrical and optical atmospheric investigations; Astrometry of the Moon during the phase evolution of the eclipse and Biological and behavioral reactions of highly organized colonies (ants and bats) during the eclipse. It is also shown that the students benefit from the activities of processing data, observational results and their interpretation, and preparation of summary reports. This exercise is intended to provide the basic training necessary to develop the creativity of the students and amateur astronomers involved. This will enable the students from the Astronomy schools at Public Astronomical Observatories and Planetaria (PAOP) to further develop their creative skills, emotional-volitional personal qualities with an orientation towards scientific analysis, using observations and experiments, to build an effective scientific style of thinking. Students of the Yuri Gagarin Public Astronomical Observatory, whom are already being nurtured in this manner, should be able to participate with great success in Scientific Research Programs devoted to the International Heliophysical Year.

Nakhleh, Mary B.; Samarapungavan, Ala; Saglam, Yilmaz

2005-05-01

The objective of this study was to examine middle school students' developing understanding of the nature of matter and to compare middle school students' ideas to those of elementary schools students, as was done by Nakhleh and Samarapungavan [J Res Sci Teach 36(7):777-805, 1999]. Nine middle school students were interviewed using a scripted, semistructured interview. The interview probed students' understanding of the composition and particulate (atomic/molecular) structure of a variety of material substances; the relationship between particulate structure and macroscopic properties such as fluidity and malleability; as well as understanding of processes such as phase transition and dissolving. The results indicate that most of the middle school students interviewed knew that matter was composed of atoms and molecules and some of them were able to use this knowledge to explain some processes such as phase transitions of water. In contrast, almost no elementary students knew that matter was composed of atoms and molecules. However, the middle school students were unable to consistently explain material properties or processes based on their knowledge of material composition. In contrast to elementary school students, who had scientifically inaccurate but relatively consistent (macrocontinuous or macroparticulate) knowledge frameworks, the middle school students could not be classified as having consistent knowledge frameworks because their ideas were very fragmented. The fragmentation of middle school students' ideas about matter probably reflects the difficulty of assimilating the microscopic level scientific knowledge acquired through formal instruction into students' initial macroscopic knowledge frameworks.

Expanding on the GLOBE Program's Atmosphere and Aerosol investigations, high school students can conduct Earth System scientific research that promotes scientific literacy in both content and the science process. Through the use of Student-Teacher-Scientist partnerships, Earth system scientific investigations can be conducted that serve the needs of the classroom as well as participating scientific investigators. During the proof-of-concept phase of this partnership model, teachers and their students developed science plans, through consultation with scientists, and began collecting atmospheric and aerosol data in support of the Gulf of Mexico Atmospheric Composition and Climate Study (GoMACCS) campaign in Houston Texas. This effort uses some pre-existing GLOBE materials, but draws on a variety of other resources to tailor the teacher development activities and intended student participation in a way that addresses local and regional problems. Students and teachers have learned about best practices in scientific inquiry and they also helped to expand the pipeline of potential future scientists and researchers for industry, academia, and government. This work began with a Student-Teacher-Scientist partnership started in 2002 during a GLOBE Aerosol Protocol Cross- Ground Validation of AERONET with MODIS Satellite Aerosol Measurements. Several other GLOBE schools, both national and international, have contributed to this research. The current project support of the intensive GoMACCS air quality and atmospheric dynamics field campaign during September and October of 2006. This model will be evaluated for wider use in other project-focused partnerships led by NOAA's Climate Program Office.

Why I teach the controversy: using creationism to teach critical thinking

PubMed Central

Honey, P. Lynne

2015-01-01

Creationism and intelligent design are terms used to describe supernatural explanations for the origin of life, and the diversity of species on this planet. Many scientists have argued that the science classroom is no place for discussion of creationism. When I began teaching I did not teach creationism, as I focused instead on my areas of expertise. Over time it became clear that students had questions about creationism, and did not understand the difference between a scientific approach to knowledge and non-scientific approaches. This led me to wonder whether ignoring supernatural views allowed them to remain as viable “alternatives” to scientific hypotheses, in the minds of students. Also, a psychology class is an ideal place to discuss not only the scientific method but also the cognitive errors associated with non-science views. I began to explain creationism in my classes, and to model the scientific thought process that leads to a rejection of creationism. My approach is consistent with research that demonstrates that teaching content alone is insufficient for students to develop critical thinking and my admittedly anecdotal experience leads me to conclude that “teaching the controversy” has benefits for science students.

Sensemaking: Conceptualizing and Coding for “Good” Student Reasoning

NASA Astrophysics Data System (ADS)

Elby, Andrew; Scherr, R.; Bing, T.

2006-12-01

Physics instructors’ goals often go beyond improving students’ conceptual understanding and problem solving. Instructors also want students to engage in inquiry, become scientific/critical thinkers, understand the scientific process, and so on. We see two problems with these “non-content” goals. First, notions such as inquiry and scientific thinking are often defined vaguely or inconsistently across the literature. Second, even when like-minded instructors share a vision of what we’d love to see our students do, descriptions of that vision are often too squishy to communicate, debate, or assess: “We know it when we see it!” In this talk and poster, we address these problems by introducing sensemaking vs. answermaking, two mindsets with which students can approach physics. Our definitions of those notions benefit from a theoretical base, and our coding scheme for sensemaking vs. answermaking displays high interrater reliability and rests upon a list of specific indicators.

Indicators that influence prospective mathematics teachers representational and reasoning abilities

2018-01-01

Representational and mathematical reasoning ability are very important ability as basic in mathematics learning process. The 2013 curriculum suggests that the use of a scientific approach emphasizes higher order thinking skills. Therefore, a scientific approach is required in mathematics learning to improve ability of representation and mathematical reasoning. The objectives of this research are: (1) to analyze representational and reasoning abilities, (2) to analyze indicators affecting the ability of representation and mathematical reasoning, (3) to analyze scientific approaches that can improve the ability of representation and mathematical reasoning. The subject of this research is the students of mathematics prospective teachers in the first semester at Private Higher Education of Bandung City. The research method of this research was descriptive analysis. The research data were collected using reasoning and representation tests on sixty-one students. Data processing was done by descriptive analysis specified based on the indicators of representation ability and mathematical reasoning that influenced it. The results of this first-year study showed that students still had many weaknesses in reasoning and mathematical representation that were influenced by the ability to understand the indicators of both capabilities. After observing the results of the first-year research, then in the second and third year, the development of teaching materials with a scientific approach in accordance with the needs of prospective students was planned.

2013-01-01

This study investigates the effectiveness of the online Flash game Disease Defenders in producing knowledge gains for concepts related to the scientific process. Disease Defenders was specifically designed to model how the scientific process is central to a variety of disciplines and science careers. An additional question relates to the game’s ability to shift attitudes toward science. Middle school classes from grades six to eight were assigned to the experimental group (n = 489) or control group (n = 367) and asked to participate in a three-session intervention. The sessions involved completing a pretest, a game play session, and taking a posttest. Students in the experimental group played Disease Defenders while students in the control group played an alternative science game. Results showed a significant increase in mean science knowledge scores for all grades in the experimental group, with sixth grade and seventh grade students gaining more knowledge than eighth grade students. Additionally, results showed a significant positive change in science attitudes only among sixth graders, who also rated their satisfaction with the game more favorably than students in higher grades. No differences in mean test scores were found between genders for science knowledge or science attitudes, suggesting that the game is equally effective for males and females. PMID:23858354

2016-12-01

Evidence suggests that incorporating quantitative reasoning exercises into existent curricular frameworks within the science, technology, engineering, and mathematics (STEM) disciplines is essential for novices' development of conceptual understanding and process skills in these domains. Despite this being the case, such studies acknowledge that students often experience difficulty in applying mathematics in the context of scientific problems. To address this concern, the present study sought to explore the impact of active demonstrations and critical reading exercises on novices' comprehension of basic statistical concepts, including hypothesis testing, experimental design, and interpretation of research findings. Students first engaged in a highly interactive height activity that served to intuitively illustrate normal distribution, mean, standard deviation, and sample selection criteria. To enforce practical applications of standard deviation and p -value, student teams were subsequently assigned a figure from a peer-reviewed primary research article and instructed to evaluate the trustworthiness of the data. At the conclusion of this exercise, students presented their evaluations to the class for open discussion and commentary. Quantitative assessment of pre- and post-module survey data indicated a statistically significant increase both in students' scientific reasoning and process skills and in their self-reported confidence in understanding the statistical concepts presented in the module. Furthermore, data indicated that the majority of students (>85%) found the module both interesting and helpful in nature. Future studies will seek to develop additional, novel exercises within this area and to evaluate the impact of such modules across a variety of STEM and non-STEM contexts.

Using a moot to develop students’ understanding of human cloning and statutory interpretation

PubMed Central

Kind, Vanessa

2017-01-01

This article reports and analyses the method and findings from a 3-year interdisciplinary project investigating how the medium of law can support understanding of socio-scientific issues. Law represents one of the most important means by which society decides and communicates its values. Activities mirroring legal processes therefore have significant potential to inform, inspire and involve school students in exploring the conceptual, social and ethical issues relating to developments in biomedical science. This article focusses on an intervention-style study in which UK-based 16- to 17-year-old students role played a Supreme Court moot, developed by modifying a domestic appeal case concerned with whether the contemporary legislation covered the creation of cloned human embryos. We draw attention to how the science of cloning has been slightly misunderstood by the courts and in science materials provided to UK school students. We argue that moot-centred engagement activities offer great potential for science communication among post-16 students and, despite the limitations of the judicial process for addressing complex socio-scientific issues, such role plays aid development of scientific and sociolegal understanding, as well as enhancing students’ self-confidence and argumentation skills.

Gresch, Helge; Hasselhorn, Marcus; Bögeholz, Susanne

2013-10-01

Dealing with socio-scientific issues in science classes enables students to participate productively in controversial discussions concerning ethical topics, such as sustainable development. In this respect, well-structured decision-making processes are essential for elaborate reasoning. To foster decision-making competence, a computer-based programme was developed that trains secondary school students (grades 11-13) in decision-making strategies. The main research question is: does training students to use these strategies foster decision-making competence? In addition, the influence of meta-decision aids was examined. Students conducted a task analysis to select an appropriate strategy prior to the decision-making process. Hence, the second research question is: does combining decision-making training with a task analysis enhance decision-making competence at a higher rate? To answer these questions, 386 students were tested in a pre-post-follow-up control-group design that included two training groups (decision-making strategies/decision-making strategies combined with a task analysis) and a control group (decision-making with additional ecological information instead of strategic training). An open-ended questionnaire was used to assess decision-making competence in situations related to sustainable development. The decision-making training led to a significant improvement in the post-test and the follow-up, which was administered three months after the training. Long-term effects on the quality of the students' decisions were evident for both training groups. Gains in competence when reflecting upon the decision-making processes of others were found, to a lesser extent, in the training group that received the additional meta-decision training. In conclusion, training in decision-making strategies is a promising approach to deal with socio-scientific issues related to sustainable development.

The Role of Student-Advisor Interactions in Apprenticing Undergraduate Researchers into a Scientific Community of Practice

Thiry, Heather; Laursen, Sandra L.

2011-12-01

Among science educators, current interest in undergraduate research (UR) is influenced both by the traditional role of the research apprenticeship in scientists' preparation and by concerns about replacing the current scientific workforce. Recent research has begun to demonstrate the range of personal, professional, and intellectual benefits for STEM students from participating in UR, yet the processes by which student-advisor interactions contribute to these benefits are little understood. We employ situated learning theory (Lave and Wenger, Situated learning: legitimate peripheral participation, Cambridge University Press, Cambridge in 1991) to examine the role of student-advisor interactions in apprenticing undergraduate researchers, particularly in terms of acculturating students to the norms, values, and professional practice of science. This qualitative study examines interviews with a diverse sample of 73 undergraduate research students from two research-extensive institutions. From these interviews, we articulate a continuum of practices that research mentors employed in three domains to support undergraduate scientists-in-training: professional socialization, intellectual support, and personal/emotional support. The needs of novice students differed from those of experienced students in each of these areas. Novice students needed clear expectations, guidelines, and orientation to their specific research project, while experienced students needed broader socialization in adopting the traits, habits, and temperament of scientific researchers. Underrepresented minority students, and to a lesser extent, women, gained confidence from their interactions with their research mentors and broadened their future career and educational possibilities. Undergraduate research at research-extensive universities exemplifies a cycle of scientific learning and practice where undergraduate researchers are mentored by graduate students and postdoctoral researchers, who are themselves apprentices to faculty members. As such, research mentors of undergraduate students should be aware of the dual scientific and educational aspects of their advising role and its significance in shaping students' identities and career trajectories.

In response to Tali and Yarden's presentation of their efforts to teach socioscientific issues, the discussants address issues of authentic versus simulated activities; teachers as learners or co-creators with their students; educating people to contribute to science-based decisionmaking; the development of such socioscientific competence; the relationship between group or participatory processes and individual development; framing real world cases for every age of student; making space to delve into the historical and social background to any scientific theory, practice, or application; educating teachers who can coach students in socioscientific inquiry; and facing off against the traditional and resurgent emphasis on highstakes, content-oriented testing of students in science.

Trajectories of collaborative scientific conceptual change: Middle school students learning about ecosystems in a CSCL environment

NASA Astrophysics Data System (ADS)

Liu, Lei

The dissertation aims to achieve two goals. First, it attempts to establish a new theoretical framework---the collaborative scientific conceptual change model, which explicitly attends to social factor and epistemic practices of science, to understand conceptual change. Second, it report the findings of a classroom study to investigate how to apply this theoretical framework to examine the trajectories of collaborative scientific conceptual change in a CSCL environment and provide pedagogical implications. Two simulations were designed to help students make connections between the macroscopic substances and the aperceptual microscopic entities and underlying processes. The reported study was focused on analyzing the aggregated data from all participants and the video and audio data from twenty focal groups' collaborative activities and the process of their conceptual development in two classroom settings. Mixed quantitative and qualitative analyses were applied to analyze the video/audio data. The results found that, overall participants showed significant improvements from pretest to posttest on system understanding. Group and teacher effect as well as group variability were detected in both students' posttest performance and their collaborative activities, and variability emerged in group interaction. Multiple data analyses found that attributes of collaborative discourse and epistemic practices made a difference in student learning. Generating warranted claims in discourse as well as the predicting, coordinating theory-evidence, and modifying knowledge in epistemic practices had an impact on student's conceptual understanding. However, modifying knowledge was found negatively related to students' learning effect. The case studies show how groups differed in using the computer tools as a medium to conduct collaborative discourse and epistemic practices. Only with certain combination of discourse features and epistemic practices can the group interaction lead to successful convergent understanding. The results of the study imply that the collaborative scientific conceptual change model is an effective framework to study conceptual change and the simulation environment may mediate the development of successful collaborative interactions (including collaborative discourse and epistemic practices) that lead to collaborative scientific conceptual change.

Teaching for conceptual change: An intervention to promote deeper understanding of diffusion and osmosis

NASA Astrophysics Data System (ADS)

Berg, Cheryl

Emergent processes are distinguished from non-emergent processes on the basis of the qualitative relationships among the agents' interactions and the causal relationships between the agents' interactions and the pattern. Research suggests students often have robust misconceptions about emergent processes (such as diffusion) because they do not have the mental model to interpret these processes This study investigates the extent to which a domain-general understanding of emergent processes can help provide students with an enhanced understanding of diffusion and osmosis This is a quasi-experimental study using non-equivalent groups design to compare the treatment and control groups. Sixty-six community college students enrolled in an introductory biology course comprised the participants. Students' prior knowledge about emergent processes, diffusion, and osmosis were assessed by pre-tests. The treatment group received the intervention -- an instructional module about the differences between scientific processes that are emergent versus processes that are non-emergent. The control group did not receive the intervention but received the process assessment to determine incoming knowledge about scientific processes and any gains in knowledge about scientific processes. Both groups received the same specific content instruction about diffusion and osmosis, which was derived from the regular and established curriculum for the course. Both groups were given post-tests to assess whether they learned the concepts, and whether they were able to achieve a deep understanding that resulted in a comprehension of the transport of substances across cell membranes and how that might be applied in particular health-related situations. Data were analyzed using t-tests and analysis of variance. No statistically significant differences were found between the two groups based on the learning measures Limitations include sample restrictions and not taking into account individual ability levels of the participants. In addition, the short length of this intervention may not provide adequate time for students to successfully acquire the schema to understand conceptually difficult science concepts such as diffusion and osmosis. Future directions of research include expanding the sample size and length of exposure to the intervention, in addition to examining the individual ability levels of the participants.

Exploring problem-based cooperative learning in undergraduate physics labs: student perspectives

NASA Astrophysics Data System (ADS)

Bergin, S. D.; Murphy, C.; Shuilleabhain, A. Ni

2018-03-01

This study examines the potential of problem-based cooperative learning (PBCL) in expanding undergraduate physics students’ understanding of, and engagement with, the scientific process. Two groups of first-year physics students (n = 180) completed a questionnaire which compared their perceptions of learning science with their engagement in physics labs. One cohort completed a lab based on a PBCL approach, whilst the other completed the same experiment, using a more traditional, manual-based lab. Utilising a participant research approach, the questionnaire was co-constructed by researchers and student advisers from each cohort in order to improve shared meaning between researchers and participants. Analysis of students’ responses suggests that students in the PBCL cohort engaged more in higher-order problem-solving skills and evidenced a deeper understanding of the scientific process than students in the more traditional, manual-based cohort. However, the latter cohort responses placed more emphasis on accuracy and measurement in lab science than the PBCL cohort. The students in the PBCL cohort were also more positively engaged with their learning than their counterparts in the manual led group.

Global Environmental Leadership and Sustainability: High School Students Teaching Environmental Science to Policymakers

Wilson, S.; Tamsitt, V. M.

2016-02-01

A two week high school course for high-achieving 10th-12th graders was developed through the combined efforts of Scripps Institution of Oceanography (SIO) Graduate Students and UC San Diego Academic Connections. For the high school students involved, one week was spent at SIO learning basic climate science and researching climate-related topics, and one week was spent in Washington D.C. lobbying Congress for an environmental issue of their choosing. The specific learning goals of the course were for students to (1) collect, analyze and interpret scientific data, (2) synthesize scientific research for policy recommendations, (3) craft and deliver a compelling policy message, and (4) understand and experience change. In this first year, 10 students conducted research on two scientific topics; sea level rise using pier temperature data and California rainfall statistics using weather stations. Simultaneous lessons on policy messaging helped students learn how to focus scientific information for non-scientists. In combining the importance of statistics from their Science lessons with effective communication from their Policy lessons, the students developed issue papers which highlighted an environmental problem, the solution, and the reason their solution is most effective. The course culminated in two days of meetings on Capitol Hill, where they presented their solutions to their Congressional and Senate Members, conversed with policymakers, and received constructive feedback. Throughout the process, the students effectively defined arguments for an environmental topic in a program developed by SIO Graduate Students.

Nursing process, as a scientific method of nursing practice, is an important tool for putting nursing knowledge into practice which increases the quality of nursing care. The study was aimed to determine the opinions of nursing students regarding the nursing process and their levels of proficiency. A total of 44 nursing students participated in this descriptive study. Data were collected by a three-part questionnaire including the opinion of students on nursing process, Gordon's functional health patterns model and the NANDA diagnoses. Data were analyzed by SPSS software. Most of the students (65.9%) believed that the nursing process was necessary. half of the students explained the diagnosis, 58.3% explained the planning, 41.3% explained the implementation, and 43.6% explained the evaluation sufficiently. It is suggested for instructors to use different teaching methods in order to develop critical thinking while teaching the nursing process.

Teachers' tendencies to promote student-led science projects: Associations with their views about science

Bencze, J. Lawrence; Bowen, G. Michael; Alsop, Steve

2006-05-01

School science students can benefit greatly from participation in student-directed, open-ended scientific inquiry projects. For various possible reasons, however, students tend not to be engaged in such inquiries. Among factors that may limit their opportunities to engage in open-ended inquiries of their design are teachers' conceptions about science. To explore possible relationships between teachers' conceptions about science and the types of inquiry activities in which they engage students, instrumental case studies of five secondary science teachers were developed, using field notes, repertory grids, samples of lesson plans and student activities, and semistructured interviews. Based on constructivist grounded theory analysis, participating teachers' tendencies to promote student-directed, open-ended scientific inquiry projects seemed to correspond with positions about the nature of science to which they indicated adherence. A tendency to encourage and enable students to carry out student-directed, open-ended scientific inquiry projects appeared to be associated with adherence to social constructivist views about science. Teachers who opposed social constructivist views tended to prefer tight control of student knowledge building procedures and conclusions. We suggest that these results can be explained with reference to human psychological factors, including those associated with teachers' self-esteem and their relationships with knowledge-building processes in the discipline of their teaching.

University-Level Teaching of Anthropogenic Global Climate Change (AGCC) via Student Inquiry

NASA Technical Reports Server (NTRS)

Bush, Drew; Sieber, Renee; Seiler, Gale; Chandler, Mark

2017-01-01

This paper reviews university-level efforts to improve understanding of anthropogenic global climate change (AGCC) through curricula that enable student scientific inquiry. We examined 152 refereed publications and proceedings from academic conferences and selected 26 cases of inquiry learning that overcome specific challenges to AGCC teaching. This review identifies both the strengths and weaknesses of each of these case studies. It is the first to go beyond examining the impact of specific inquiry instructional approaches to offer a synthesis of cases. We find that inquiry teaching can succeed by concretising scientific processes, providing access to global data and evidence, imparting critical and higher order thinking about AGCC science policy and contextualising learning with places and scientific facts. We recommend educational researchers and scientists collaborate to create and refine curricula that utilise geospatial technologies, climate models and communication technologies to bring students into contact with scientists, climate data and authentic AGCC research processes. Many available science education technologies and curricula also require further research to maximise trade-offs between implementation and training costs and their educational value.

Examining Educational Climate Change Technology: How Group Inquiry Work with Realistic Scientific Technology Alters Classroom Learning

NASA Astrophysics Data System (ADS)

Bush, Drew; Sieber, Renee; Seiler, Gale; Chandler, Mark

2018-04-01

This study with 79 students in Montreal, Quebec, compared the educational use of a National Aeronautics and Space Administration (NASA) global climate model (GCM) to climate education technologies developed for classroom use that included simpler interfaces and processes. The goal was to show how differing climate education technologies succeed and fail at getting students to evolve in their understanding of anthropogenic global climate change (AGCC). Many available climate education technologies aim to convey key AGCC concepts or Earth systems processes; the educational GCM used here aims to teach students the methods and processes of global climate modeling. We hypothesized that challenges to learning about AGCC make authentic technology-enabled inquiry important in developing accurate understandings of not just the issue but how scientists research it. The goal was to determine if student learning trajectories differed between the comparison and treatment groups based on whether each climate education technology allowed authentic scientific research. We trace learning trajectories using pre/post exams, practice quizzes, and written student reflections. To examine the reasons for differing learning trajectories, we discuss student pre/post questionnaires, student exit interviews, and 535 min of recorded classroom video. Students who worked with a GCM demonstrated learning trajectories with larger gains, higher levels of engagement, and a better idea of how climate scientists conduct research. Students who worked with simpler climate education technologies scored lower in the course because of lower levels of engagement with inquiry processes that were perceived to not actually resemble the work of climate scientists.

The technology-science relationship: Some curriculum implications

NASA Astrophysics Data System (ADS)

Gardner, Paul L.

1990-01-01

Technology encompasses the goods and services which people make and provide to meet human needs, and the processes and systems used for their development and delivery. Although technology and science are related, a distinction can be made between their purposes and outcomes. This paper considers four possible approaches to teaching students about the relationship between technology and science. A technology-as-illustration approach treats technology as if it were applied science; artefacts are presented to illustrate scientific principles. A cognitive-motivational approach also treats technology as applied science, but presents technology early in the instructional sequence in order to promote student interest and understanding. In an artefact approach, learners study artefacts as systems in order to understand the scientific principles which explain their workings. Finally, a technology-as-process approach emphasises the role of technological capability; in this approach, scientific concepts do not have privileged status as a basis for selecting curriculum content.

Epistemic beliefs of middle and high school students in a problem-based, scientific inquiry unit: An exploratory, mixed methods study

NASA Astrophysics Data System (ADS)

Gu, Jiangyue

Epistemic beliefs are individuals' beliefs about the nature of knowledge, how knowledge is constructed, and how knowledge can be justified. This study employed a mixed-methods approach to examine: (a) middle and high school students' self-reported epistemic beliefs (quantitative) and epistemic beliefs revealed from practice (qualitative) during a problem-based, scientific inquiry unit, (b) How do middle and high school students' epistemic beliefs contribute to the construction of students' problem solving processes, and (c) how and why do students' epistemic beliefs change by engaging in PBL. Twenty-one middle and high school students participated in a summer science class to investigate local water quality in a 2-week long problem-based learning (PBL) unit. The students worked in small groups to conduct water quality tests at in their local watershed and visited several stakeholders for their investigation. Pretest and posttest versions of the Epistemological Beliefs Questionnaire were conducted to assess students' self-reported epistemic beliefs before and after the unit. I videotaped and interviewed three groups of students during the unit and conducted discourse analysis to examine their epistemic beliefs revealed from scientific inquiry activities and triangulate with their self-reported data. There are three main findings from this study. First, students in this study self-reported relatively sophisticated epistemic beliefs on the pretest. However, the comparison between their self-reported beliefs and beliefs revealed from practice indicated that some students were able to apply sophisticated beliefs during the unit while others failed to do so. The inconsistency between these two types of epistemic beliefs may due to students' inadequate cognitive ability, low validity of self-report measure, and the influence of contextual factors. Second, qualitative analysis indicated that students' epistemic beliefs of the nature of knowing influenced their problem solving processes and construction of arguments during their inquiry activities. Students with more sophisticated epistemic beliefs acquired knowledge, presented solid evidence, and used it to support their claims more effectively than their peers. Third, students' self-reported epistemic beliefs became significantly more sophisticated by engaging in PBL. Findings from this study can potentially help researchers to better understand the relation between students' epistemic beliefs and their scientific inquiry practice,

Using Interactive Technology to Support Students' Understanding of the Greenhouse Effect and Global Warming

Varma, Keisha; Linn, Marcia C.

2012-08-01

In this work, we examine middle school students' understanding of the greenhouse effect and global warming. We designed and refined a technology-enhanced curriculum module called Global Warming: Virtual Earth. In the module activities, students conduct virtual experiments with a visualization of the greenhouse effect. They analyze data and draw conclusions about how individual variables effect changes in the Earth's temperature. They also carry out inquiry activities to make connections between scientific processes, the socio-scientific issues, and ideas presented in the media. Results show that participating in the unit increases students' understanding of the science. We discuss how students integrate their ideas about global climate change as a result of using virtual experiments that allow them to explore meaningful complexities of the climate system.

An exploration of fifth-grade students' epistemological beliefs in science and an investigation of their relation to science learning

NASA Astrophysics Data System (ADS)

Elder, Anastasia Danos

Elementary students' beliefs about the nature of knowledge---epistemological beliefs---are an emerging concern for science education and research. Composed of a critique of research literature and two studies, this dissertation investigated the epistemological beliefs of fifth-grade students who participated in inquiry-based, hands-on science program. The goals were to characterize their beliefs about the nature of knowledge in science and to investigate the relation between these beliefs and their learning of scientific process skills. In the first study, fifth-grade students (N = 211) were surveyed about their beliefs regarding the (1) purpose of science, (2) sources of scientific knowledge, (3) roles of evidence and experiments, (4) changing nature of knowledge in science, and (5) coherence of a scientific knowledge base. Descriptive statistics and analysis of variance (ANOVA) were conducted to assess the interrelations among various epistemological belief constructs. Fifth-graders' epistemological beliefs in science were found to reflect a mixture of naive and sophisticated understanding. Few differences in beliefs were found according to gender, ethnicity, and socio-economic status. Students' understanding of the purpose of science and the changing nature of science seemed to act as two important constructs in their beliefs. Furthermore, students' epistemological beliefs was characterized as an emerging system in which beliefs were related to each other in consistent ways. In the second study, fifth-grade students (N = 194) responded to questionnaire items about their epistemological beliefs in science and completed performance assessments testing their science process skills in two units---one which embedded learning of process skills with conceptual knowledge and another in which process skills were learned with minimal reference to conceptual knowledge. Based on correlational and ANOVA analyses, modest links were found between students' epistemological beliefs and their science learning. The relations varied by instructional unit. Findings defined a number of areas for further investigation including a consideration of how beliefs are characterized, a greater emphasis on understanding the role of aptitude and prior knowledge, and developmental issues in the relation between students' epistemological beliefs and their learning of science. Theoretical, methodological, and educational implications of this work were discussed.

Gondwana Tales: an inquiry approach to plate tectonics

NASA Astrophysics Data System (ADS)

Domènech Casal, Jordi

2014-05-01

Plate tectonics and its effects on the constitution of seas and continents are key models in science education. Fossil evidences are usually taught in demostrative key when Wegener's discoverings about Pangea are introduced. In order to introduce inquiry-based science education (IBSE) approaches to this topic, we propose "Gondwana Tales", an activity where students are asked to use fossil data to reconstruct the geologic history of an imaginary planet. Grouped in independent teams, each team is furnished with stratigraphic columns from several sites containing faunistic successions of real organisms existing in the past in Earth. Students are told to reconstruct a model of the evolution of the continents, by making calculations of relative ages of the fossils, and relating each fossil to a geologic era. The different teams have incomplete and complementary information. After a first step where they have to propose a partial model based on incomplete data, each team receives a "visitor scientist" from another team, this implying an informal scientific communication event. This process is performed several times, engaging a discussion in each team and getting a final consensus model created by the whole class. Correct answer is not given to the students, even at the end of the activity, to keep the activity under the parameters of real scientific experience, where there is not a "correct answer" to compare. Instead of this, and following the IBSE standards, a reflection on the process is proposed to students. The lack of complete information and the need to collaborate are part of classroom dynamics focused to the understanding of the process of creation of the scientific knowledge. This activity is part of the C3 Project on Creation of Scientific Knowledge that is being applied in the school.

Doing, talking and writing science: A discourse analysis of the process of resemiotization in a middle school lab-based science class

NASA Astrophysics Data System (ADS)

Wright, Laura J.

This study examines students' sense making practices in a middle school science class from a discourse analytic perspective. Using Mediated Discourse Analysis (MDA) (Scollon 1998, 2001) and interactional sociolinguistics (Gumperz 1999, 2001, Schiffrin 1994), my research seeks to enrich findings from recent sociocultural studies of science classrooms that focus on doing, talking and writing science (Roth 2005, Kress, et al. 2002, Halliday & Martin 1993, Lemke 1990). Within a middle school science classroom, these fundamental activities form a nexus of practice (Scollon 1998, 2001) basic to science literacy (AAAS 1989) and reflective of the work of practicing scientists. Moreover, students' engagement in these practices provides insight into the cultural production and reproduction of science and scientist. I first examine how the students' curriculum text encourages these three scientific practices and then trace students' uptake; that is, how they subsequently do, talk, and write science throughout the course of the unit. I argue that learning science with this curriculum unit requires students to resemiotize (Iedema 2001, 2003) first hand experience so they can represent their knowledge cohesively and coherently in evaluable forms. Ultimately, students must transform language from the curriculum text and their teacher into action in their laboratory activities and action in their laboratory activities into language. In addition, I show how students are apprenticed to the conventionalized practices and voices (Bakhtin 1986) of science (i.e. the scientific register), and how their figures of personhood (Agha 2005) reflect the development of their scientific identities. Overall, I argue that the microanalytic methods I use illuminate how students draw upon curricular resources to become scientifically literate and develop scientific identities.

In order to achieve the set aim, the following scientific research methods were used: analysis of the conceptual guidelines for the development of environmentally oriented entrepreneurship, interpretation of the experts' evaluation of the ecologically oriented management, analysis of the results of the students' ecologically oriented independent scientific research, as well as monographic and logically constructive methods. The results of the study give an opportunity to make conclusions and to develop conceptual recommendations on how to introduce future economics and business professionals with the theoretical and practical aspects of ecologically oriented management during the study process.

Intentions and actions in molecular self-assembly: perspectives on students' language use

Höst, Gunnar E.; Anward, Jan

Learning to talk science is an important aspect of learning to do science. Given that scientists' language frequently includes intentions and purposes in explanations of unobservable objects and events, teachers must interpret whether learners' use of such language reflects a scientific understanding or inaccurate anthropomorphism and teleology. In the present study, a framework consisting of three 'stances' (Dennett, 1987) - intentional, design and physical - is presented as a powerful tool for analysing students' language use. The aim was to investigate how the framework can be differentiated and used analytically for interpreting students' talk about a molecular process. Semi-structured group discussions and individual interviews about the molecular self-assembly process were conducted with engineering biology/chemistry (n = 15) and biology/chemistry teacher students (n = 6). Qualitative content analysis of transcripts showed that all three stances were employed by students. The analysis also identified subcategories for each stance, and revealed that intentional language with respect to molecular movement and assumptions about design requirements may be potentially problematic areas. Students' exclusion of physical stance explanations may indicate literal anthropomorphic interpretations. Implications for practice include providing teachers with a tool for scaffolding their use of metaphorical language and for supporting students' metacognitive development as scientific language users.

Students as researchers: What and why seventh‐grade students choose to write when investigating their own research question

Abstract All scientists depend on both reading and writing to do their scientific work. It is of paramount importance to ensure that students have a relevant repertoire of practices they can employ when facing scientific content inside and outside the school context. The present study reports on students in seventh grade acting as researchers. Over an 8‐week collaborative research period, students posed their own research question, attempted to answer it by systematically testing hypotheses, discussing findings, presenting their conclusions, and documenting their process in a written report. Drawing on the perspectives of New Literacy Studies—which sees literacy as socially situated—we analyze the purpose of all the 21 participating students’ texts (n = 344). Video observations and interviews with students are used to contextualize the writing events. We find that the students chose to write multiple kinds of texts for a variety of purposes. Analyzing purpose and the context, three stages of socialization into scientific writing is revealed, ranging from what the students write on their own initiative, via texts written through challenges to demanding research tasks scaffolded through writing instructions given by the teacher. Further, the students emphasized the relevance of both the research experience and the writing to their future adult life. PMID:29540938

The effects of different styles of interaction on the learning of evolutionary theories

NASA Astrophysics Data System (ADS)

Sugimoto, Akiko

This study investigated the effects of different styles of social interaction on the learning of advanced biological knowledge. Recent research has increasingly acknowledged the importance of social interaction for promoting learning and cognitive development. However, there has been a controversy about the optimal style of interaction. Some studies have showed the beneficial effects of symmetrical interactions such as an argument between peers, whereas other studies have found the superiority of asymmetrical interactions in which a novice learn with the guidance of an expert. The reason for the contradictory results may be that different styles of interaction enhance different kinds of learning. The present study focused on the three styles of interaction; (1) Conflicting style, in which two novice students with scientifically wrong but conflicting views argue with one another, (2) Guiding style, in which a novice student is led by a more expert student to an understanding of scientifically appropriate knowledge, (3) Mutual Constructive style, in which an expert student and a novice student jointly solve a scientific problem on an equal footing. Sixty college students with non-biology-majors and 30 students with a biology major participated in this experiment to discuss an evolutionary problem in these three styles of interaction, with the former serving as novices and the latter as experts. Analyses of the Pre- and the Posttest performance and discussion processes in the Interaction session revealed the following. First, the Guiding style and the Mutual Constructive style enhanced the acquisition of the scientific evolutionary conceptual framework more effectively than the Conflicting style. However, some students in the Conflicting style also grasped the scientific evolutionary framework, and many students reconstructed their theories of evolution through discussion, even if the frameworks remained scientifically inappropriate. Second, the students who discussed evolution in the Conflicting style and the Mutual Constructive style tended to become more reflective and flexible than the students in the Guiding style, when solving a new evolutionary problem. Third, analyses of epistemological beliefs and critiques of evolutionary explanations suggested that the Mutual Constructive style and the Conflicting style facilitated the development of critical thinking more than the Guiding style.

Evidence suggests that incorporating quantitative reasoning exercises into existent curricular frameworks within the science, technology, engineering, and mathematics (STEM) disciplines is essential for novices’ development of conceptual understanding and process skills in these domains. Despite this being the case, such studies acknowledge that students often experience difficulty in applying mathematics in the context of scientific problems. To address this concern, the present study sought to explore the impact of active demonstrations and critical reading exercises on novices’ comprehension of basic statistical concepts, including hypothesis testing, experimental design, and interpretation of research findings. Students first engaged in a highly interactive height activity that served to intuitively illustrate normal distribution, mean, standard deviation, and sample selection criteria. To enforce practical applications of standard deviation and p-value, student teams were subsequently assigned a figure from a peer-reviewed primary research article and instructed to evaluate the trustworthiness of the data. At the conclusion of this exercise, students presented their evaluations to the class for open discussion and commentary. Quantitative assessment of pre- and post-module survey data indicated a statistically significant increase both in students’ scientific reasoning and process skills and in their self-reported confidence in understanding the statistical concepts presented in the module. Furthermore, data indicated that the majority of students (>85%) found the module both interesting and helpful in nature. Future studies will seek to develop additional, novel exercises within this area and to evaluate the impact of such modules across a variety of STEM and non-STEM contexts. PMID:28101271

Designing Courses that Encourage Post-College Scientific Literacy in General Education Students

NASA Astrophysics Data System (ADS)

Horodyskyj, L.

2010-12-01

In a time when domestic and foreign policy is becoming increasingly dependent on a robust understanding of scientific concepts (especially in regards to climate science), it is of vital importance that non-specialist students taking geoscience courses gain an understanding not only of Earth system processes, but also of how to discern scientific information from "spin". An experimental introductory level environmental geology course was developed at the Glendale Community College in Glendale, Arizona, in the fall of 2010 that sought to integrate collaborative learning, online resources, and science in the media. The goal of this course was for students to end the semester with not just an understanding of basic Earth systems concepts, but also with a set of tools for evaluating information presented by the media. This was accomplished by integrating several online sites that interface scientific data with popular web tools (ie, Google Maps) and collaborative exercises that required students to generate ideas based on their observations followed by evaluation and refinement of these ideas through interactions with peers and the instructor. The capstone activity included a series of homework assignments that required students to make note of science-related news stories in the media early in the semester, and then gradually begin critically evaluating these news sources, which will become their primary source of post-college geoscience information. This combination of activities will benefit students long after the semester has ended by giving them access to primary sources of scientific information, encouraging them to discuss and evaluate their ideas with their peers, and, most importantly, to critically evaluate the information they receive from the media and their peers so that they can become more scientifically literate citizens.

The next generation of data capturing - digital ink for the data stewards of the future

NASA Astrophysics Data System (ADS)

Czerniak, A.; Fleischer, D.; Schirnick, C.

2012-12-01

Data stewardship of the future requires the continuation from an expert driven discipline into a general scientific routine. One solution how this expansion can be done is the use of data management infrastructures already in the student education. Unsurprisingly, well-known drawbacks in terms of data stewardship from the scientific use complicate this expansion into the educational programs. The advantage of educational programs usually based on the application of standard methods is depleted by the general data capturing process at the point of publication or end of project lifetime. Considering student courses as short projects there are no publications and the end of the course exams keep students just like scientists away from data stewardship tasks. The Kiel Data Management Infrastructure brings the data capturing right in the data creation process. With this approach student education courses can be just another use case of data capturing. Smoothing the data capturing process and making use of available technologies drove the Kiel Data Management Infrastructure into a prototype testing of the use of 'digital ink' and the later on possible handwriting recognition. Making the data digitalization as easy as possible without abandoning the standards of paper-based protocols is the use case 'Smart Pens'. This technology fills the gap between the very long-lasting paper protocols and the effort depending digitalization of field and sampling data but it's also robust enough to work with battery powered devices. The combination of the Kiel Data Management Infrastructure with the 'digital ink' technology enables the data capturing from student education to high-end scientific lab work. Valuing educational data equally to scientific lab data is a strong signal to the researchers of the future while their work is recognized all the way from their undergraduate stage to their post-doc position. Students memorize that their data work is not neglected at any time and so they realize that their is no excuse of keeping any data away from the data management infrastructure. The technology of 'digital ink' is a milestone for the data stewardship discipline and fits perfectly into the a lot of gaps between the data creation and the data infrastructure and as long as we do not establish the life long data capturing support for the scientific career we can not complain about reluctant data submissions.

Challenging traditional assumptions of high school science through the physics and Everyday Thinking Curriculum(TM)

NASA Astrophysics Data System (ADS)

Ross, Michael J.

Science education in the U.S. has failed for over a century to bring the experience of scientific induction to classrooms, from elementary science to undergraduate courses. The achievement of American students on international comparisons of science proficiency is unacceptable, and the disparities between groups underrepresented in STEM and others are large and resistant to reform efforts. This study investigated the enactment of a physics curriculum designed upon the inductive method in a high school serving mostly students from groups underrepresented in science. The Physics and Everyday Thinking curriculum was designed to model the central practices of science and to provide opportunities for students to both extract general principles of physics and to develop scientific models from laboratory evidence. The findings of this study suggest that scientific induction is not only a process that is well within the capacity of high school students, but they enjoy it as well. Students that engaged in the central practices of science through the inductive method reported a new sense of agency and control in their learning. These findings suggest that modeling the pedagogy of the science classroom upon the epistemology of science can result in a mode of learning that can lead to positive identification with physics and the development of scientific literacy.

Young children learning about living things: A case study of conceptual change from ontological and social perspectives

NASA Astrophysics Data System (ADS)

Venville, Grady

2004-05-01

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case-study design and qualitative data-collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5- and 6-year-old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5-week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment.

Developing students' worksheets applying soft skill-based scientific approach for improving building engineering students' competencies in vocational high schools

2017-09-01

Experts and practitioners agree that the quality of vocational high schools needs to be greatly improved. Many construction services have voiced their dissatisfaction with today's low-quality vocational high school graduates. The low quality of graduates is closely related to the quality of the teaching and learning process, particularly teaching materials. In their efforts to improve the quality of vocational high school education, the government have implemented Curriculum 2013 (K13) and supplied teaching materials. However, the results of monitoring and evaluation done by the Directorate of Vocational High School, Directorate General of Secondary Education (2014), the provision of tasks for students in the teaching materials was totally inadequate. Therefore, to enhance the quality and the result of the instructional process, there should be provided students' worksheets that can stimulate and improve students' problem-solving skills and soft skills. In order to develop worksheets that can meet the academic requirements, the development needs to be in accordance with an innovative learning approach, which is the soft skill-based scientific approach.

2016-01-01

This study has aimed to evaluate the level of knowledge about the first aid process among the university students in Jordan. The study population consisted of students of the 14 scientific and unscientific faculties at Yarmouk University, Jordan. Data were obtained via questionnaires from 883 students. The majority of participants were females (65.9%) with mean age (standard deviation) of 19.9 (2.6) years. Only 29.2% of students had previous first aid experience. When asked, only 11% of students knew the normal respiration rate of an adult in 1 min. Results revealed that female students, having previous first aid experience, and being a student of the health sciences and scientific colleges were the only factors had significant statistical associations with better level of first aid knowledge. The students' knowledge about first aid is not at an adequate level. It would be advisable that first aid course be handled as a separate and practical course at secondary school level.

Zhong, Hairong; Xu, Wei; Hu, Haojun; Duan, Chengfang

2017-08-01

This article analyzes the features of fostering optoelectronic students' innovative practical ability based on the knowledge structure of optoelectronic disciplines, which not only reveals the common law of cultivating students' innovative practical ability, but also considers the characteristics of the major: (1) The basic theory is difficult, and the close combination of science and technology is obvious; (2)With the integration of optics, mechanics, electronics and computer, the system technology is comprehensive; (3) It has both leading-edge theory and practical applications, so the benefit of cultivating optoelectronic students is high ; (4) The equipment is precise and the practice is costly. Considering the concept and structural characteristics of innovative and practical ability, and adhering to the idea of running practice through the whole process, we put forward the construction of three-dimensional innovation and practice platform which consists of "Synthetically Teaching Laboratory + Innovation Practice Base + Scientific Research Laboratory + Major Practice Base + Joint Teaching and Training Base", and meanwhile build a whole-process progressive training mode to foster optoelectronic students' innovative practical ability, following the process of "basic experimental skills training - professional experimental skills training - system design - innovative practice - scientific research project training - expanded training - graduation project": (1) To create an in - class practical ability cultivation environment that has distinctive characteristics of the major, with the teaching laboratory as the basic platform; (2) To create an extra-curricular innovation practice activities cultivation environment that is closely linked to the practical application, with the innovation practice base as a platform for improvement; (3) To create an innovation practice training cultivation environment that leads the development of cutting-edge, with the scientific research laboratory as a platform to explore; (4) To create an out-campus expanded training environment of optoelectronic major practice and optoelectronic system teaching and training, with the major practice base as an expansion of the platform; (5) To break students' "pre-job training barriers" between school and work, with graduation design as the comprehensive training and testing link.

Preparing Scientists to be Community Partners

NASA Astrophysics Data System (ADS)

Pandya, R. E.

2012-12-01

Many students, especially students from historically under-represented communities, leave science majors or avoid choosing them because scientific careers do not offer enough opportunity to contribute to their communities. Citizen science, or public participation in scientific research, may address these challenges. At its most collaborative, it means inviting communities to partner in every step of the scientific process from defining the research question to applying the results to community priorities. In addition to attracting and retaining students, this level of community engagement will help diversify science, ensure the use and usability of our science, help buttress public support of science, and encourage the application of scientific results to policy. It also offers opportunities to tackle scientific questions that can't be accomplished in other way and it is demonstrably effective at helping people learn scientific concepts and methods. In order to learn how to prepare scientists for this kind of intensive community collaboration, we examined several case studies, including a project on disease and public health in Africa and the professionally evaluated experience of two summer interns in Southern Louisiana. In these and other cases, we learned that scientific expertise in a discipline has to be accompanied by a reservoir of humility and respect for other ways of knowing, the ability to work collaboratively with a broad range of disciplines and people, patience and enough career stability to allow that patience, and a willingness to adapt research to a broader set of scientific and non-scientific priorities. To help students achieve this, we found that direct instruction in participatory methods, mentoring by community members and scientists with participatory experience, in-depth training on scientific ethics and communication, explicit articulation of the goal of working with communities, and ample opportunity for personal reflection were essential. There is much more to learn about preparing students for these collaborative approaches, and the principal goal of sharing these strategies is to spark a conversation about the ways we prepare scientists and the public to work together in an increasingly collaborative scientific enterprise.

Methods of Science Investigation Part 2: Results of Implementation of a Curriculum Fostering Original Scientific Research

NASA Astrophysics Data System (ADS)

Danch, J. M.

2008-12-01

Originally designed to allow secondary students with special needs to participate in original scientific research, the Methods of Science Curriculum was piloted in 2008. Students participating included those with special needs, English language learners, and the general population. Students were incrementally graduated from traditional inquiry activities towards authentic student-generated research projects. Students were evaluated via class work grades, an in-school symposium and a pre/post test. 100 percent of participants successfully completed and presented their original research. The pre/post evaluation demonstrated improvement for 91 percent of participants. An unanticipated result was the performance and growth of English language learners, possibly because of the emphasis on the creative and active process of science rather than vocabulary. A teacher-training program is being developed for expansion of the curriculum to additional schools in 2009.

The impact of collaborative groups versus individuals in undergraduate inquiry-based astronomy laboratory learning exercises

NASA Astrophysics Data System (ADS)

Sibbernsen, Kendra J.

One of the long-standing general undergraduate education requirements common to many colleges and universities is a science course with a laboratory experience component. One of the objectives frequently included in the description of most of these courses is that a student will understand the nature and processes of scientific inquiry. However, recent research has shown that learners in traditional undergraduate science laboratory environments are not developing a sufficiently meaningful understanding of scientific inquiry. Recently, astronomy laboratory activities have been developed that intentionally scaffold a student from guided activities to open inquiry ones and preliminary results show that these laboratories are successful for supporting students to understand the nature of scientific inquiry (Slater, S., Slater, T. F., & Shaner, 2008). This mixed-method quasi-experimental study was designed to determine how students in an undergraduate astronomy laboratory increase their understanding of inquiry working in relative isolation compared to working in small collaborative learning groups. The introductory astronomy laboratory students in the study generally increased their understanding of scientific inquiry over the course of the semester and this held true similarly for students working in groups and students working individually in the laboratories. This was determined by the examining the change in responses from the pretest to the posttest administration of the Views of Scientific Inquiry (VOSI) survey, the increase in scores on laboratory exercises, and observations from the instructor. Because the study was successful in determining that individuals in the astronomy laboratory do as well at understanding inquiry as those who complete their exercises in small groups, it would be appropriate to offer these inquiry-based exercises in an online format.

Science teaching deals with abstract concepts and processes that very often cannot be seen or touched. The development of Java, Flash, and other web-based applications allow teachers and educators to present complex animations that attractively illustrate scientific phenomena. Our study evaluated the integration of web-based animated movies into primary schools science curriculum. Our goal was to examine teachers' methods for integrating animated movies and their views about the role of animations in enhancing young students' thinking skills. We also aimed at investigating the effect of animated movies on students' learning outcomes. Applying qualitative and quantitative tools, we conducted informal discussions with science teachers (N = 15) and administered pre- and post-questionnaires to 4th (N = 641) and 5th (N = 694) grade students who were divided into control and experimental groups. The experimental group students studied science while using animated movies and supplementary activities at least once a week. The control group students used only textbooks and still-pictures for learning science. Findings indicated that animated movies support the use of diverse teaching strategies and learning methods, and can promote various thinking skills among students. Findings also indicated that animations can enhance scientific curiosity, the acquisition of scientific language, and fostering scientific thinking. These encouraging results can be explained by the fact that the students made use of both visual-pictorial and auditory-verbal capabilities while exploring animated movies in diverse learning styles and teaching strategies.

The collection of large quantities of scientific data has not only transformed science, but holds the potential to transform teaching and learning by engaging students in authentic scientific work. Furthermore, it has become imperative in a data-rich world that students gain competency in working with and interpreting data. The Next Generation Science Standards reflect both the opportunity and need for greater integration of data in science education, and emphasize that both scientific knowledge and practice are essential elements of science learning. The process of enabling access by novice learners to data collected and used by experts poses significant challenges, however, recent research has demonstrated that barriers to student learning with data can be overcome by the careful design of data access and analysis tools that are specifically tailored to students. A group of educators at Education Development Center, Inc. (EDC) and scientists at Stanford University's Hopkins Marine Station are collaborating to develop and test a model for student engagement with scientific data using a web-based platform. This model, called Ocean Tracks: Investigating Marine Migrations in a Changing Ocean, provides students with the ability to plot and analyze tracks of migrating marine animals collected through the Tagging of Pacific Predators program. The interface and associated curriculum support students in identifying relationships between animal behavior and physical oceanographic variables (e.g. SST, chlorophyll, currents), making linkages between the living world and climate. Students are also supported in investigating possible sources of human impact to important biodiversity hotspots in the Pacific Ocean. The first round of classroom testing revealed that students were able to easily access and display data on the interface, and collect measurements from the animal tracks and oceanographic data layers. They were able to link multiple types of data to draw powerful inferences about how marine animal behavior is influenced by the ocean environment, and propose strategies to protect marine animals in the context of a changing ocean. Classroom testing also revealed the importance of providing students with real-world context to their learning, and the opportunity to directly compare their scientific investigations of data with those of scientists in the field. Our results also identified that student engagement was enhanced when they developed a direct personal connection to their scientific investigations by linking human activities to changes occurring in the natural world, and visualizing these changes using authentic data. This presentation will review the design elements of the Ocean Tracks interface and associated curriculum, our successes and challenges in supporting students in data based learning, and discuss specific linkages to the NGSS.

2003-01-01

Question-asking is a basic skill, required for the development of scientific thinking. However, the way in which science lessons are conducted does not usually stimulate question-asking by students. To make students more familiar with the scientific inquiry process, we developed a curriculum in developmental biology based on research papers suitable for high-school students. Since a scientific paper poses a research question, demonstrates the events that led to the answer, and poses new questions, we attempted to examine the effect of studying through research papers on students' ability to pose questions. Students were asked before, during, and after instruction what they found interesting to know about embryonic development. In addition, we monitored students' questions, which were asked orally during the lessons. Questions were scored according to three categories: properties, comparisons, and causal relationships. We found that before learning through research papers, students tend to ask only questions of the properties category. In contrast, students tend to pose questions that reveal a higher level of thinking and uniqueness during or following instruction with research papers. This change was not observed during or following instruction with a textbook. We suggest that learning through research papers may be one way to provide a stimulus for question-asking by high-school students and results in higher thinking levels and uniqueness. PMID:14673492

Learning How Scientists Work: Experiential Research Projects to Promote Cell Biology Learning and Scientific Process Skills

2002-01-01

Facilitating not only the mastery of sophisticated subject matter, but also the development of process skills is an ongoing challenge in teaching any introductory undergraduate course. To accomplish this goal in a sophomore-level introductory cell biology course, I require students to work in groups and complete several mock experiential research projects that imitate the professional activities of the scientific community. I designed these projects as a way to promote process skill development within content-rich pedagogy and to connect text-based and laboratory-based learning with the world of contemporary research. First, students become familiar with one primary article from a leading peer-reviewed journal, which they discuss by means of PowerPoint-based journal clubs and journalism reports highlighting public relevance. Second, relying mostly on primary articles, they investigate the molecular basis of a disease, compose reviews for an in-house journal, and present seminars in a public symposium. Last, students author primary articles detailing investigative experiments conducted in the lab. This curriculum has been successful in both quarter-based and semester-based institutions. Student attitudes toward their learning were assessed quantitatively with course surveys. Students consistently reported that these projects significantly lowered barriers to primary literature, improved research-associated skills, strengthened traditional pedagogy, and helped accomplish course objectives. Such approaches are widely suited for instructors seeking to integrate process with content in their courses. PMID:12669101

Mutation-based learning to improve student autonomy and scientific inquiry skills in a large genetics laboratory course.

Wu, Jinlu

2013-01-01

Laboratory education can play a vital role in developing a learner's autonomy and scientific inquiry skills. In an innovative, mutation-based learning (MBL) approach, students were instructed to redesign a teacher-designed standard experimental protocol by a "mutation" method in a molecular genetics laboratory course. Students could choose to delete, add, reverse, or replace certain steps of the standard protocol to explore questions of interest to them in a given experimental scenario. They wrote experimental proposals to address their rationales and hypotheses for the "mutations"; conducted experiments in parallel, according to both standard and mutated protocols; and then compared and analyzed results to write individual lab reports. Various autonomy-supportive measures were provided in the entire experimental process. Analyses of student work and feedback suggest that students using the MBL approach 1) spend more time discussing experiments, 2) use more scientific inquiry skills, and 3) find the increased autonomy afforded by MBL more enjoyable than do students following regimented instructions in a conventional "cookbook"-style laboratory. Furthermore, the MBL approach does not incur an obvious increase in labor and financial costs, which makes it feasible for easy adaptation and implementation in a large class.

Scientific attitude is need of today's society for peaceful and meaningful living of every person in a multicultural world. A case study was conducted at the Faculty of Teacher Training and Education, University of Riau, Pekanbaru in order to describe the scientific attitude that shaped by research-based teaching (RBT). Eighteen students of English for Biology bilingual program were selected from 88 regular students as a subject of the study. RBT designed consists of 9 steps: 1) field observations, 2) developing research proposals, 3) research proposal seminar, 4) field data collecting, 5) data analyzing & ilustrating, 6) writing research papers, 7) preparing power point slides, 8) creating a scientific poster, 9) seminar & poster session. Data were collected by using check list observation instuments during 14 weeks (course sessions), then analyzed by using descriptive-quantitative method. The results showed that RBT were able to shape critical-mindedness, suspended judgement, respect for evidence, honesty, objectivity, and questioning attitude as well as tolerance of uncertainty. These attitudes which shaped were varies according to every steps of learning activities. It's seems that the preparation of scientific posters and research seminar quite good in shaping the critical-mindedness, suspended judgment, respect for evidence, honesty, objectivity, and questioning attitude, as well as tolerance of uncertainty. In conclusion, the application of research-based teaching through the English for Biology courses could shape the students scientific attitudes. However, the consistency of the appearance of a scientific attitude in every stage of Biology-based RBT learning process need more intensive and critical assessment.

Active learning has gained increasing support as an effective pedagogical technique to improve student learning. One way to promote active learning in the classroom is the use of in-class activities in place of lecturing. As part of an NSF-funded project, a set of in-class activities have been created that use climate change topics to teach chemistry content. These activities use the Process Oriented Guided Inquiry Learning (POGIL) methodology. In this pedagogical approach a set of models and a series of critical thinking questions are used to guide students through the introduction to or application of course content. Students complete the activities in their groups, with the faculty member as a facilitator of learning. Through assigned group roles and intentionally designed activity structure, process skills, such as teamwork, communication, and information processing, are developed during completion of the activity. Each of these climate change activities contains a socio-scientific component, e.g., social, ethical and economic data. In one activity, greenhouse gases are used to explain the concept of dipole moment. Data about natural and anthropogenic production rates, global warming potential and atmospheric lifetimes for a list of greenhouse gases are presented. The students are asked to identify which greenhouse gas they would regulate, with a corresponding explanation for their choice. They are also asked to identify the disadvantages of regulating the gas they chose in the previous question. In another activity, where carbon sequestration is used to demonstrate the utility of a phase diagram, students use economic and environmental data to choose the best location for sequestration. Too often discussions about climate change (both in and outside the classroom) consist of purely emotional responses. These activities force students to use data to support their arguments and hypothesize about what other data could be used in the corresponding discussion to support their position. In this presentation, we will present examples of the socio-scientific components of several activities, and discuss the challenges associated with incorporating socio-scientific components into content-based class activities.

Integrating Explicit Learning about the Culture of Science into the Pre-Service Teacher Curriculum through Readings and Reflections

NASA Astrophysics Data System (ADS)

Egger, A. E.

2014-12-01

Teachers provide foundational science experiences that spark interest in some students to pursue science and serve as an endpoint for others. For both groups, getting a glimpse into the culture of science is important to their futures as citizens, but this glimpse is not something all teachers are equipped to offer. Explicit instruction in the culture of science is generally not part of college-level science courses; to reach future teachers, it should be incorporated into the curriculum for pre-service teachers. I have incorporated readings from Visionlearning's peer-reviewed, freely available, web-based Process of Science series (http://www.visionlearning.com/en/library/Process-of-Science/49) into my class for pre-service middle-level and secondary science teachers. The readings describe the development of the culture and process of science using deeply embedded examples of scientists and their work. Students reflected on each reading by describing what they learned and something they will use in their future teaching. Responses were graded for thoughtfulness and completeness and later compiled. In general, students with more science courses had a better initial understanding of the culture of science and found the readings engaging stories that explained in more depth what they already knew. However, all students reported learning some fundamental aspects of the culture and nature of science. Most commonly, they learned scientific language, often words with both colloquial and scientific definitions: theory, hypothesis, law, uncertainty, error, confidence. Other learning gains were reported in defining the difference between scientific controversy and social controversy over science, interactions between historical events and the scientific enterprise, how much scientists work in groups and interact at meetings, and the role that funding plays in guiding research. On their own, students struggled to describe explicit ways to incorporate these concepts into their teaching, though many felt it was very important to do so. In follow-up discussions and activities, we developed strategies to promote bringing the culture of science explicitly into the middle-level and secondary science classroom. The readings gave them ideas and are a resource they and their students can continue to access.

A multidisciplinary faculty committee designed a curriculum to shape biomedical graduate students into researchers with a high commitment to professionalism and social responsibility and to provide students with tools to navigate complex, rapidly evolving academic and societal environments with a strong ethical commitment. The curriculum used problem-based learning (PBL), because it is active and learner-centred and focuses on skill and process development. Two courses were developed: Scientific Professionalism: Scientific Integrity addressed discipline-specific and broad professional norms and obligations for the ethical practice of science and responsible conduct of research (RCR). Scientific Professionalism: Bioethics and Social Responsibility focused on current ethical and bioethical issues within the scientific profession, and implications of research for society. Each small-group session examined case scenarios that included: (1) learning objectives for professional norms and obligations; (2) key ethical issues and philosophies within each topic area; (3) one or more of the RCR instructional areas; and (4) at least one type of moral reflection. Cases emphasised professional standards, obligations and underlying philosophies for the ethical practice of science, competing interests of stakeholders and oversight of science (internal and external). To our knowledge, this is the first use of a longitudinal, multi-semester PBL course to teach scientific integrity and professionalism. Both faculty and students endorsed the active learning approach for these topics, in contrast to a compliance-based approach that emphasises learning rules and regulations.

Genetics problem solving and worldview

NASA Astrophysics Data System (ADS)

Dale, Esther

The research goal was to determine whether worldview relates to traditional and real-world genetics problem solving. Traditionally, scientific literacy emphasized content knowledge alone because it was sufficient to solve traditional problems. The contemporary definition of scientific literacy is, "The knowledge and understanding of scientific concepts and processes required for personal decision-making, participation in civic and cultural affairs and economic productivity" (NRC, 1996). An expanded definition of scientific literacy is needed to solve socioscientific issues (SSI), complex social issues with conceptual, procedural, or technological associations with science. Teaching content knowledge alone assumes that students will find the scientific explanation of a phenomenon to be superior to a non-science explanation. Formal science and everyday ways of thinking about science are two different cultures (Palmer, 1999). Students address this rift with cognitive apartheid, the boxing away of science knowledge from other types of knowledge (Jedege & Aikenhead, 1999). By addressing worldview, cognitive apartheid may decrease and scientific literacy may increase. Introductory biology students at the University of Minnesota during fall semester 2005 completed a written questionnaire-including a genetics content-knowledge test, four genetic dilemmas, the Worldview Assessment Instrument (WAI) and some items about demographics and religiosity. Six students responded to the interview protocol. Based on statistical analysis and interview data, this study concluded the following: (1) Worldview, in the form of metaphysics, relates to solving traditional genetic dilemmas. (2) Worldview, in the form of agency, relates to solving traditional genetics problems. (3) Thus, worldview must be addressed in curriculum, instruction, and assessment.

What matters in the classroom: A structural model of standards-based scientific literacy

NASA Astrophysics Data System (ADS)

Shive, Louise E.

For over two decades educators and policy makers have been particularly concerned with student achievement in the wake of A Nation at Risk. A majority of studies indicates that students' family background has the strongest influence on achievement, although characteristics of their teachers and schools have significant impact as well. This study considered achievement in science in particular, investigating the influence of alterable factors within the classroom on students' gains in scientific literacy. Scientific literacy included three elements: content knowledge, scientific process skills, and attitude towards science. Based on a review of the literature on student achievement, a structural equation model was constructed with five latent variables: teacher's education, instructional practices, teacher's attitudes, school's context, and students' scientific literacy. The model was tested using data from the five-month implementation of a standards-based integrated text/technology/laboratory program, Biology: Exploring Life. The sixteen biology teachers completed two pre-implementation surveys, and 664 of their students completed the three pretests and the corresponding posttests. The initial model did not fit well (chi2(80) = 2784.16; chi 2/df = 34.80; GFI = .70; IFI = .49; CFI = .49) and was inadmissible due to the presence of negative variances. After revision of the model, fit improved somewhat (chi2(53) = 1623.97; chi 2/df = 30.64; GFI = .77; IFI = .65; CFI = .65), although a negative variance migrated and persisted. The total effects were greatest for the teacher's attitudes (largely indirect, mediated through instructional practices), followed by school's context, and instructional practices. Teacher's education had the lowest total effects due to almost equal but opposite direct effects (positive) and indirect effects (mediated through instructional practices and teacher's attitudes). The investigator concluded that alterable factors such as teachers' attitudes, instructional practices, and classroom context can influence students' gains in scientific literacy within a standards-based integrated text/technology/laboratory program.

Conceptual change strategies in teaching genetics

NASA Astrophysics Data System (ADS)

Batzli, Laura Elizabeth

The purpose of this study was to evaluate the effectiveness of utilizing conceptual change strategies when teaching high school genetics. The study examined the effects of structuring instruction to provide students with cognitive situations which promote conceptual change, specifically instruction was structured to elicit students' prior knowledge. The goal of the study was that the students would not only be able to solve genetics problems and define basic terminology but they would also have constructed more scientific schemas of the actual processes involved in inheritance. This study is based on the constructivist theory of learning and conceptual change research which suggest that students are actively involved in the process of relating new information to prior knowledge as they construct new knowledge. Two sections of biology II classes received inquiry based instruction and participated in structured cooperative learning groups. However, the unique difference in the treatment group's instruction was the use of structured thought time and the resulting social interaction between the students. The treatment group students' instructional design allowed students to socially construct their cognitive knowledge after elicitation of their prior knowledge. In contrast, the instructional design for the control group students allowed them to socially construct their cognitive knowledge of genetics without the individually structured thought time. The results indicated that the conceptual change strategies with individually structured thought time improved the students' scientific mastery of genetics concepts and they maintained fewer post instructional alternative conceptions. Although all students gained the ability to correctly solve genetics problems, the treatment group students were able to explain the processes involved in terms of meiosis. The treatment group students were also able to better apply their knowledge to novel genetic situations. The implications for genetics instruction from these results were discussed.

The active involvement of young researchers in scientific processes and the acquisition of scientific experience by gifted youth currently have a great value for the development of science. One of the research activities of National Research Tomsk Polytechnic University, aimed at the preparing and formation of the next generation of scientists, is the International Conference of Students and Young Scientists ''Modern Techniques and Technologies'', which was held in 2014 for the twentieth time. Great experience in the organization of scientific events has been acquired through years of carrying the conference. There are all the necessary resources for this: a team of organizers - employees of Tomsk Polytechnic University, premises provided with modern office equipment and equipment for demonstration, and leading scientists - professors of TPU, as well as the status of the university as a leading research university in Russia. This way the conference is able to attract world leading scientists for the collaboration. For the previous years the conference proved itself as a major scientific event at international level, which attracts more than 600 students and young scientists from Russia, CIS and other countries. The conference provides oral plenary and section reports. The conference is organized around lectures, where leading Russian and foreign scientists deliver plenary presentations to young audiences. An important indicator of this scientific event is the magnitude of the coverage of scientific fields: energy, heat and power, instrument making, engineering, systems and devices for medical purposes, electromechanics, material science, computer science and control in technical systems, nanotechnologies and nanomaterials, physical methods in science and technology, control and quality management, design and technology of artistic materials processing. The main issues considered by young researchers at the conference were related to the analysis of contemporary problems using new techniques and application of new technologies.

The journal IMPULSE offers undergraduates worldwide the opportunity to publish research and serve as peer reviewers for the submissions of others. Undergraduate faculty have recognized the journal’s value in engaging students working in their labs in the publication process. However, integration of scientific publication into an undergraduate laboratory classroom setting has been lacking. We report here on a course at Ursinus College where 20 students taking Molecular Neurobiology were required to submit manuscripts to IMPULSE. The syllabus allowed for the laboratory research to coincide with the background research and writing of the manuscript. Students completed their projects on the impact of drugs on the Daphnia magna nervous system while producing manuscripts ready for submission by week 7 of the course. Findings from a survey completed by the students and perceptions of the faculty member teaching the course indicated that students spent much more time writing, were more focused on completing the assays, completed the assays with larger data sets, were more engaged in learning the scientific concepts and were more thorough with their revisions of the paper knowing that it might be published. Further, the professor found she was more thorough in critiquing students’ papers knowing they would be externally reviewed. Incorporating journal submission into the course stimulated an in depth writing experience and allowed for a deeper exploration of the topic than students would have experienced otherwise. This case study provides evidence that IMPULSE can be successfully used as a means of incorporating scientific publication into an undergraduate laboratory science course. This approach to teaching undergraduate neuroscience allows for a larger number of students to have hands-on research and scientific publishing experience than would be possible with the current model of a few students in a faculty member’s laboratory. This report illustrates that IMPULSE can be incorporated as an integral part of an academic curriculum with positive outcomes on student engagement and performance. PMID:23494013

Exploring Third-Grade Student Model-Based Explanations about Plant Relationships within an Ecosystem

Elementary students should have opportunities to develop scientific models to reason and build understanding about how and why plants depend on relationships within an ecosystem for growth and survival. However, scientific modeling practices are rarely included within elementary science learning environments and disciplinary content is often treated as discrete pieces separate from scientific practice. Elementary students have few, if any, opportunities to reason about how individual organisms, such as plants, hold critical relationships with their surrounding environment. The purpose of this design-based research study is to build a learning performance to identify and explore the third-grade students' baseline understanding of and their reasoning about plant-ecosystem relationships when engaged in the practices of modeling. The developed learning performance integrated scientific content and core scientific activity to identify and measure how students build knowledge about the role of plants in ecosystems through the practices of modeling. Our findings indicate that the third-grade students' ideas about plant growth include abiotic and biotic relationships. Further, they used their models to reason about how and why these relationships were necessary to maintain plant stasis. However, while the majority of the third-grade students were able to identify and reason about plant-abiotic relationships, a much smaller group reasoned about plant-abiotic-animal relationships. Implications from the study suggest that modeling serves as a tool to support elementary students in reasoning about system relationships, but they require greater curricular and instructional support in conceptualizing how and why ecosystem relationships are necessary for plant growth and development. This paper is based on data from a doctoral dissertation. An earlier version of this paper was presented at the 2015 international conference for the National Association for Research in Science Teaching (NARST) Zangori, L., & Forbes, C. T. (2015).

Curriculum design and simulation courses are bridges to connect specialty theories, engineering practice and experimental skills. In order to help students to have the computer aided optical system design ability adapting to developments of the times, a professional optical software-Advanced System of Analysis Program (ASAP) was used in the research teaching of curriculum design and simulation courses. The ASAP tutorials conducting, exercises both complementing and supplementing the lectures, hands-on practice in class, autonomous learning and independent design after class were bridged organically, to guide students "learning while doing, learning by doing", paying more attention to the process instead of the results. Several years of teaching practice of curriculum design and simulation courses shows that, project-based learning meets society needs of training personnel with knowledge, ability and quality. Students have obtained not only skills of using professional software, but also skills of finding and proposing questions in engineering practice, the scientific method of analyzing and solving questions with specialty knowledge, in addition, autonomous learning ability, teamwork spirit and innovation consciousness, still scientific attitude of facing failure and scientific spirit of admitting deficiency in the process of independent design and exploration.

To optimize the teaching-learning process it is fundamental to know the representations that students have regarding knowledge. Epistemological beliefs are implicit theories that guide the practical actions of people. To characterize and compare epistemological beliefs regarding the nature and acquisition of scientific knowledge of health career students. Between 2012 and 2013, 726 students coursing first, third or fifth year from six health careers answered a validated questionnaire that includes closed and open questions aimed to characterize their epistemological beliefs about scientific knowledge. Irrespective of the career, when students had to select predefined answers, most of them appeared as constructivists (61%). On the other hand, when they had to argue, the majority seemed objectivist (47%). First-year medical students have the highest frequency of constructivist epistemological beliefs (56%). Paradoxically, the lowest percentage is found (34%) in the fifth year. The students of the health careers, in particular those of Medicine, recognize that knowledge is not acquired immediately (83%) and that its distribution is shared (92%). Discordance between selections and arguments suggests that epistemological sophistication is achieved declaratively but not practically. The lower proportion of students who presented constructivist beliefs in the fifth year compared to first year of Medicine could be associated with the pedagogical approaches used in the different cycles of the career.

Using Nonfiction Narratives in an English Course to Teach the Nature of Science and Its Importance to Communicating About Science †

Aune, Jeanine Elise; Evans, Lynn Lundy; Boury, Nancy

The nature of science (NOS) is a foundational framework for understanding scientific ideas and concepts. This framework includes scientific methodology, the process of revising and interpreting data, and the ways in which science is a social endeavor. Nature of science literature treats science as a way of knowing that is based on observable phenomenon. While discipline-specific coursework teaches the factual information of science, it may fall short on teaching scientific literacy, a key component of which is understanding NOS. We have designed an English course that features nonfiction narratives describing the early days of epidemiology, hygiene awareness, and the current controversy surrounding vaccination. Using a validated assessment of student understanding of NOS, the Student Understanding of Science and Scientific Inquiry (SUSSI), we have determined that this science-themed English composition course was effective in teaching NOS. Student understanding of NOS increased between the beginning and the end of the course in eight of the nine parameters of NOS measured, with the greatest gains in understanding the role of revision and of creativity in science. Our data imply that the course helped students develop a slightly less naïve understanding of the nature of science and its importance in the development and dissemination of scientific ideas and concepts.

Making authentic science accessible-the benefits and challenges of integrating bioinformatics into a high-school science curriculum.

2017-01-01

Despite the central place held by bioinformatics in modern life sciences and related areas, it has only recently been integrated to a limited extent into high-school teaching and learning programs. Here we describe the assessment of a learning environment entitled 'Bioinformatics in the Service of Biotechnology'. Students' learning outcomes and attitudes toward the bioinformatics learning environment were measured by analyzing their answers to questions embedded within the activities, questionnaires, interviews and observations. Students' difficulties and knowledge acquisition were characterized based on four categories: the required domain-specific knowledge (declarative, procedural, strategic or situational), the scientific field that each question stems from (biology, bioinformatics or their combination), the associated cognitive-process dimension (remember, understand, apply, analyze, evaluate, create) and the type of question (open-ended or multiple choice). Analysis of students' cognitive outcomes revealed learning gains in bioinformatics and related scientific fields, as well as appropriation of the bioinformatics approach as part of the students' scientific 'toolbox'. For students, questions stemming from the 'old world' biology field and requiring declarative or strategic knowledge were harder to deal with. This stands in contrast to their teachers' prediction. Analysis of students' affective outcomes revealed positive attitudes toward bioinformatics and the learning environment, as well as their perception of the teacher's role. Insights from this analysis yielded implications and recommendations for curriculum design, classroom enactment, teacher education and research. For example, we recommend teaching bioinformatics in an integrative and comprehensive manner, through an inquiry process, and linking it to the wider science curriculum. © The Author 2016.

Community development in a Research Experience for Teachers (RET) program: Teacher growth and translation of the experience back to the classroom

Johnston, Carol Suzanne Chism

This qualitative study explores how a scientific research experience helped seven secondary science teachers to grow professionally. The design of this Research Experience for Teachers (RET) program emphasized having teachers become members of university scientific research communities---participating in experimental design, data collection, analysis, and presenting of findings---in order to have a better understanding of research science. I conducted individual interviews with teacher and scientist participants, visited the teachers in their laboratories, videotaped classroom visits, and videotaped group meetings during the summers to learn what teachers brought back to their classrooms about the processes of science. I examined the teachers' views of research science, views shaped by their exposure to research science under the mentorship of a scientist participant. The teachers observed the collaborative efforts of research scientists and experienced doing scientific research, using technology and various experimental methods. Throughout their two-year experience, the teachers continually refined their images of scientists. I also examined how teachers in this program built a professional community as they developed curricula. Further, I investigated what the teachers brought from their experiences back to the classroom, deciding on a theme of "Communicating Science" as a way to convey aspects of scientific inquiry to students. Teacher growth as a result of this two-year program included developing more empathy for student learning and renewing their enthusiasm for both learning and teaching science. Teacher growth also included developing curricula to involve students in behaving as scientists. The teachers identified a few discrete communication practices of scientists that they deemed appropriate for students to adopt to increase their communication skills. Increased community building in classes to model scientific communities was seen as a way to motivate students and to help them to understand scientific concepts.

How to Teach High-School Students "How Science Really Works?"

NASA Astrophysics Data System (ADS)

Losiak, Anna; Students, High-School; Winiarska, Anna; Parys-Wasylkiewicz, Magdalena

2016-04-01

One of the largest problems in Poland (as well as in the large part of the developed world) is that people do not understand how science works. Based on what they learned at school, they think that science is an aggregation of facts that you need to learn by heart. Based on media coverage of the science topics, they think it is a collection of curiosities about the two-headed-snakes. Based on the way in which science is shown in movies and TV series, they envision science as a magic performed in a white coat with usage of colorful fluids and magic spells such as "transformative hermeneutics of quantum gravity". As a result, our societies include a large number of people who "do not believe" in evolution, think that vaccinations are causing autism and that anthropogenic global warming is a myth. This is not very surprising, given that most people never had a chance to perform a real scientific experiment. Most of people, if they are lucky, are able to see some science demonstrations in the classrooms. They are of course very useful, but it is quite clear for everyone that (if everything goes well) the demonstration can end up in one, pre-defined way. The "real" scientific experiment, as a part of the scientific process, is when the outcome is unknown until the end of the entire process. In order to teach high-school students "How Science Really Works" we have developed a project lasting one year (grant from Foundation for Polish Science 26/UD/SKILLS/2015): 1) At first students learned about scientific method, science history and performed a simple scientific experiment. 2) Later, students developed an experiment that was answering a real, unanswered scientific problem (the problem was given by the Leading Scientist). The aim of the project was to determine influence of albedo and emissivity of rock particles laying on a surface of a glacier on the rate of cryoconite holes formation. The results of this experiment can be used to better determine the rate of melting terrestrial glaciers and Martian North Polar Residual Cap. 3) Students were responsible for physically preparing scientific equipment (within a given budget). 4) Students prepared detailed procedures which were used during the experiment. The experiment was performed by the Austrian Space Forum analog astronauts during the Mars Analog Mission AMADEE-15 between 2nd and 14th of August 2015 at the Kaunertal Glacier in Austria. 5) During and after the mission students analyzed data collected during the experiment. 6) Students presented their findings during the regional science fair (Dolnoslaski Festiwal Nauki). Despite the fact the quality of the data produced during the experiment was not satisfactory, the project was a success in terms of explaining students "How Science Really Works" (e.g., how much depends on the properly designed and executed procedures).

The effects of conducting authentic field-geology research on high school students' understanding of the nature of science, and their views of themselves as research scientists

NASA Astrophysics Data System (ADS)

Millette, Patricia M.

Authentic field geology research is a inquiry method that encourages students to interact more with their local environment, and by solving genuine puzzles, begin to increase their intuitive understanding of the nature and processes of science. The goal of the current study was to determine if conducting authentic field research and giving high school students the opportunity to present findings to adult audiences outside of the school setting 1) enhances students' understanding of the nature of science, and 2) affects students views of themselves as researchers. To accomplish this, ninth-grade students from a public school in northern New England engaged in a community-initiated glacial geology problem, completed a field research investigation, and presented their findings at several professional conferences. Following the completion of this student-centered field research, I investigated its effects by using a mixed methods approach consisting of qualitative and quantitative data from two sources. These included selected questions from an open-response survey (VNOS-c), and interviews that were conducted with fifteen of the students of different ages and genders. Findings show that conducting original field research seems to have a positive influence on these students' understanding of the NOS as well as the processes of science. Many of the students reported feelings of accomplishment, acceptance of responsibility for the investigation, a sense of their authentic contribution to the body of scientific knowledge in the world, and becoming scientists. This type of authentic field investigation is significant because recent reforms in earth-science education stress the importance of students learning about the nature and processes of scientific knowledge along with science content.

Can medical schools teach high school students to be scientists?

Rosenbaum, James T; Martin, Tammy M; Farris, Kendra H; Rosenbaum, Richard B; Neuwelt, Edward A

2007-07-01

The preeminence of science in the United States is endangered for multiple reasons, including mediocre achievement in science education by secondary school students. A group of scientists at Oregon Health and Science University has established a class to teach the process of scientific inquiry to local high school students. Prominent aspects of the class include pairing of the student with a mentor; use of a journal club format; preparation of a referenced, hypothesis driven research proposal; and a "hands-on" laboratory experience. A survey of our graduates found that 73% were planning careers in health or science. In comparison to conventional science classes, including chemistry, biology, and algebra, our students were 7 times more likely to rank the scientific inquiry class as influencing career or life choices. Medical schools should make research opportunities widely available to teenagers because this experience dramatically affects one's attitude toward science and the likelihood that a student will pursue a career in science or medicine. A federal initiative could facilitate student opportunities to pursue research.

Arguing from Nature: The role of `nature' in students' argumentations on a socio-scientific issue

NASA Astrophysics Data System (ADS)

Nielsen, Jan Alexis

2012-03-01

This paper explores how students invoked different conceptions of 'nature' in eight socio-scientific group discussions about human gene therapy. The paper illustrates and discusses how the students articulated nature and to what extent they elicited science factual content in the process. While the students in this study invoked nature at key places in a variety of dialectical contexts in the discussions, these invocations were often uncritical appeals and rarely involved science factual content. Even when an argument from nature was challenged, the author of that argument would often shift the sense of nature rather than elaborate upon the argumentation. It is argued that if students were properly introduced to the evaluative character of the term 'nature' it would not just be conducive to the quality of their argumentation, but also invite them to foreground science factual content at key places in their discussion.

Verbal and social interaction patterns among elementary students during self-guided "I Wonder Projects"

NASA Astrophysics Data System (ADS)

Huziak, Tracy Lynn

National standards for science teaching stress the use of inquiry teaching methods. One example of inquiry teaching is the I Wonder Project, which has been used in the Madison, WI Metropolitan School District for over ten years. The purpose of the I Wonder Project is to promote scientific discourse among elementary students through the publication of their research in a journal, similar in some ways to the scientific discourse within a community of scientists. This research study utilizes the I Wonder Project method to encourage student communication and self-guided project work. Approximately fifteen students ages 6--12 participated in a six-week self-guided inquiry project called I Wonder. Students worked as a cohort to learn science process skills and to build a scientific community. During this time, each student designed and carried out a self-guided inquiry project and wrote an article about their findings, which was presented on the last day of summer camp. A mixed method approach was used conduct this study. Participants were given a pretest and a posttest to determine the changes in scientific process skills as a result of participation in the project. The students were interviewed to determine their ideas about science and how those ideas changed over the time of participation in summer camp. Also the students were observed by the researchers, as well as audio- and video-taped to capture the verbal conversations and debates that take place as a result of discussion of ideas during the program. Students participated in this study as individuals and group members. Teacher and student interactions were noted to follow three main interaction styles: structured, guided and open-ended. These interactions work much like the inquiry levels described in the literature. Students also interacted with each other in three different ways: independently, dependently, and multifunctioning. Some students wished to work alone, while others preferred others to contribute to their work as well. Finally, there were five main types of science talk described by this study based on Gee's (1997) four types of science talk: design and debate, anomaly talk, everyday speculation talk, and explanation talk. What was also noted was an overwhelming amount of prior experience talk. Because students were given free choice in their topics of study, many chose to study topics that they had some interest or prior experience with. This led to a comparison of current findings to those they had already anticipated or expected. This study shows that self-guided inquiry projects require a range of interaction styles between students and also teachers. Many students need differing levels of support in order to be successful. In addition, it is important that students have an opportunity to select a topic of choice so that they have the opportunity to build on their scientific knowledge from their prior experiences.

2007-04-01

The aim of this study was to investigate the effectiveness of a problem-based learning (PBL) approach in a physical chemistry laboratory course. The parameters investigated were students’ attitudes towards a chemistry laboratory course, scientific process skills of students and their academic achievement. The design of the study was one group pre-test post-test. Four experiments, covering the topics adsorption, viscosity, surface tension and conductivity were performed using a PBL approach in the fall semester of the 2003/04 academic year at Kazim Karabekir Education Faculty of Atatürk University. Each experiment was done over a three week period. A total of 40 students, 18 male and 22 female, participated in the study. Students took the Physical Chemistry Laboratory Concept Test (PCLCT), Attitudes towards Chemistry Laboratory (ATCL) questionnaire and Science Process Skills Test (SPST) as pre and post-tests. In addition, the effectiveness of the PBL approach was also determined through four different scales; Scales Specific to Students’ Views of PBL.

Using Communication Technology to Facilitate Scientific Literacy: A Framework for Engaged Learning

NASA Astrophysics Data System (ADS)

VanBuskirk, Shireen Adele

The purpose of this research project is to describe how existing communication technologies are used to foster scientific literacy for secondary students. This study develops a new framework as an analytic tool to categorize the activities of teachers and students involved in scientific literacy to describe what elements of scientific literacy are facilitated by such technologies. Four case studies are analyzed using the framework to describe the scientific literacy initiatives. Data collection at each site included interviews with the teacher, student focus groups, student surveys, and classroom observations. Qualitative analysis of the data provided insight into the learning activities and student experiences in the four cases. This study intentionally provides a platform for student voice. Very few previous empirical studies in the area of scientific literacy include the student experience. This represents a significant gap in the current literature on scientific literacy. An interpretation of scientific literacy that promotes student engagement, interaction, and initiative corresponds to a need to listen to students' perspectives on these experiences. Findings of the study indicated that the classroom activities depended on the teacher's philosophy regarding scientific literacy. Communication technology was ubiquitous; where the teacher did not initiate the use of social media in the classroom, the students did. The goal of supporting scientific literacy in students is an objective that extends beyond the boundaries of classroom walls, and it can be facilitated by technologies that seem both abundant and underutilized. Technology-enhanced pedagogy altered the classroom practices and resulted in more student participation and engagement.

What can we teachers do? For students we can provide a strong background in the process of science and in scientific ethics. We can encourage students to apply such knowledge wisely throughout their lives. For the public at large, we can speak out in favor of real science at every opportunity. It is possible that the current scientific consensus on global warming is based on incomplete evidence, but global warming ought not be dismissed as unscientific or a hoax, and scientists ought not allow that to happen. As we celebrate National Chemistry Week, we should resolve to support chemistry and science as strongly as we can.

Teaching scientific thinking skills: Students and computers coaching each other

NASA Astrophysics Data System (ADS)

Reif, Frederick; Scott, Lisa A.

1999-09-01

Our attempts to improve physics instruction have led us to analyze thought processes needed to apply scientific principles to problems—and to recognize that reliable performance requires the basic cognitive functions of deciding, implementing, and assessing. Using a reciprocal-teaching strategy to teach such thought processes explicitly, we have developed computer programs called PALs (P_ersonal A_ssistants for L_earning) in which computers and students alternately coach each other. These computer-implemented tutorials make it practically feasible to provide students with individual guidance and feedback ordinarily unavailable in most courses. We constructed PALs specifically designed to teach the application of Newton's laws. In a comparative experimental study these computer tutorials were found to be nearly as effective as individual tutoring by expert teachers—and considerably more effective than the instruction provided in a well-taught physics class. Furthermore, almost all of the students using the PALs perceived them as very helpful to their learning. These results suggest that the proposed instructional approach could fruitfully be extended to improve instruction in various practically realistic contexts.

Process skills acquisition, cognitive growth, and attitude change of ninth grade students in a scientific literacy course

NASA Astrophysics Data System (ADS)

Baker, Dale R.; Piburn, Michael

This is a report of the effects of a scientific literacy course on the skills, cognitive ability, and attitude of students in the first year of high school. Specifically, the research examines (1) whether it is possible to teach scientific skills, (2) whether a literacy curriculum affects attitude and cognitive ability, and (3) whether incoming student characteristics affect the development of attitude and cognitive abilities. Two hundred and fifty (126 male and 124 female) ninth grade students were enrolled in a specially designed literacy course which met for 3 hours and 20 minutes each week for 39 weeks. Students were pretested for logical, spatial, verbal, and mathematical ability, as well as for attitude toward self and science, and psychological type. The course was successful in teaching skills. In addition, there were significant increases in spatial, verbal, and quantitative ability. Increases in cognitive ability were predicted by logical ability, measurement skills, and academic self-concept. Attitudes declined as a result of participation in the course. Self concept and mastery were related to cognitive variables and motivation, mastery, and control were related to psychological type.

A tale of two slinkies: learning about scientific models in a student-driven classroom

NASA Astrophysics Data System (ADS)

Gandhi, Punit; Berggren, Calvin; Livezey, Jesse; Olf, Ryan

2014-11-01

We describe a set of conceptual activities and hands-on experiments based around understanding the dynamics of a slinky that is hung vertically and released from rest. The motion, or lack thereof, of the bottom of the slinky after the top is dropped sparks students' curiosity by challenging their expectations and provides context for learning about scientific model building. This curriculum helps students learn about the model building process by giving them an opportunity to enlist their collective intellectual and creative resources to develop and explore two different physical models of the falling slinky system. By engaging with two complementary models, students not only have the opportunity to understand an intriguing phenomenon from multiple perspectives, but also learn deeper lessons about the nature of scientific understanding, the role of physical models, and the experience of doing science. The activities we present were part of a curriculum developed for a week-long summer program for incoming freshmen as a part of the Compass Project at UC Berkeley, but could easily be implemented in a wide range of classrooms at the high school or introductory college level.

The gross anatomy laboratory: a novel venue for critical thinking and interdisciplinary teaching in dental education.

Rowland, Kevin C; Joy, Anita

2015-03-01

Reports on the status of dental education have concluded that there is a need for various types of curricular reform, making recommendations that include better integration of basic, behavioral, and clinical sciences, increased case-based teaching, emphasis on student-driven learning, and creation of lifelong learners. Dental schools faced with decreasing contact hours, increasing teaching material, and technological advancements have experimented with alternate curricular strategies. At Southern Illinois University School of Dental Medicine, curricular changes have begun with a series of integrated biomedical sciences courses. During the process of planning and implementing the integrated courses, a novel venue-the gross anatomy laboratory-was used to introduce all Year 1 students to critical thinking, self-directed learning, and the scientific method. The venture included student-driven documentation of anatomical variations encountered in the laboratory using robust scientific methods, thorough literature review, and subsequent presentation of findings in peer review settings. Students responded positively, with over 75% agreeing the experience intellectually challenged them. This article describes the process of re-envisioning the gross anatomy laboratory as an effective venue for small group-based, student-driven projects that focus on key pedagogical concepts to encourage the development of lifelong learners.

Fourth and fifth grade Latino(a) students making meaning of scientific informational texts

NASA Astrophysics Data System (ADS)

Croce, Keri-Anne

Using a socio-psycholinguistic perspective of literacy and a social-semiotic analysis of texts, this study investigates how six students made meaning of informational texts. The students came to school from a variety of English and Spanish language backgrounds. The research question being asked was 'How do Latino(a) fourth and fifth grade students make meaning of English informational texts?' Miscue analysis was used as a tool to investigate how students who have been labeled non-struggling readers by their classroom teacher and are from various language backgrounds approached five informational texts. In order to investigate students' responses to the nature of informational texts, this dissertation draws on commonly occurring structures within texts. Primary data collected included read alouds and retellings of five texts, retrospective miscue analysis, and interviews with six participant students. Two of these participants are discussed within this dissertation. Secondary data included classroom observations and teacher interviews. This study proposes that non-native speakers may use scientific concept placeholders as they transact with informational texts. The use of scientific concept placeholders by a reader indicates that the reader is engaged in the meaning making process and possesses evolving scientific knowledge about a phenomenon. The findings suggest that Latino(a) students' understandings of English informational texts is influenced not only by a student's language development but also (1) the nature of the text; (2) the reading strategies that a student uses, such as the use of placeholders; (3) the influence of the researcher during the aided retelling. This study contributes methodological tools to assess English language learners' reading. The conclusions presented within this study also support the idea that students from a variety of language backgrounds slightly altered their reliance on certain cuing systems as they encountered various sub-genres within an informational text. I conclude that reading assessment should account for how a student approaches different structural elements of a text.

The persistence of personal and social themes in context: Long- and short-term studies of students' scientific ideas

NASA Astrophysics Data System (ADS)

Helldén, Gustav F.; Solomon, Joan

2004-11-01

In this paper we will examine the persistence of misconceptions. We used data from a longitudinal study of personal ideas in 24 students' thinking about ecological processes. The results show students often speaking about personal experiences dating from an early age, to which they had also referred in similar interviews conducted years before. These data are compared with results from a different study of middle school physics students' thinking about energy and steam engines. After the new learning had been successfull completed and assessed, old ideas returned. These findings are used to set up a theoretical basis for understanding the longitudinal results. Findings from memory studies are shown to explicate the long-term effects of the passage of time and prompts for the recall of scientific concepts.

Role of the Undergraduate Student Research Assistant in the New Millennium

PubMed Central

2004-01-01

In this study, we analyze the contribution of the undergraduate student who participates in the process of generating scientific data and developing a research project using Brazilian research as an example. Historically, undergraduate students have performed the critical role of research assistants in developing countries. This aspect has been underappreciated as a means of generating scientific data in Brazilian research facilities. Brazilian educational institutions are facing major age-related generational changes among the science faculty within the next 5–10 yr. A lack of adequate support for graduate students leads to a concern that undergraduates will not be interested in choosing research assistant programs and, subsequently, academic research careers. To remedy this situation it is important to focus on ways to encourage new research careers and enhance university–industry collaborations. PMID:15592596

Mutation-Based Learning to Improve Student Autonomy and Scientific Inquiry Skills in a Large Genetics Laboratory Course

PubMed Central

Wu, Jinlu

2013-01-01

Laboratory education can play a vital role in developing a learner's autonomy and scientific inquiry skills. In an innovative, mutation-based learning (MBL) approach, students were instructed to redesign a teacher-designed standard experimental protocol by a “mutation” method in a molecular genetics laboratory course. Students could choose to delete, add, reverse, or replace certain steps of the standard protocol to explore questions of interest to them in a given experimental scenario. They wrote experimental proposals to address their rationales and hypotheses for the “mutations”; conducted experiments in parallel, according to both standard and mutated protocols; and then compared and analyzed results to write individual lab reports. Various autonomy-supportive measures were provided in the entire experimental process. Analyses of student work and feedback suggest that students using the MBL approach 1) spend more time discussing experiments, 2) use more scientific inquiry skills, and 3) find the increased autonomy afforded by MBL more enjoyable than do students following regimented instructions in a conventional “cookbook”-style laboratory. Furthermore, the MBL approach does not incur an obvious increase in labor and financial costs, which makes it feasible for easy adaptation and implementation in a large class. PMID:24006394

Involvement of young people into science at the present time is relevant not only in Russia but as well in countries with big experience in this process. The article states that profession of scientist is considered prestigious in the United States and positioned at 4th place in the rating, wheras in Russia it is only at 19th place in the similar rating. The conclusion is based on the sociological studies conducted in the United States and Russia. The authors speculate that changes in public policy in Russia, aimed at recovering of scientific potential, had an impact on young people's ideas and motivation for scientific work. The article provides an analysis of the sociological study conducted by the National Research Tomsk Polytechnic University (TPU), which aims to determine the willingness and possibility to engage in scientific work. The authors note that TPU entered the federal program “5-100-2020” at 4th place in the ranking of the best universities in Russia and has extensive experience, research base, international training programs, exchanges, and internships with best universities in the United States and Europe. The main conclusions of the study is that master students are ready to engage in scientific work; conditions created at the university are the backbone for the development of scientific career of the students; the highest motivation for students is the satisfaction in their scientific advisors.

2009-12-01

Our program in the School of Marine and Atmospheric Sciences at Stony Brook University is unique in emphasizing the interdisciplinary study of coastal ocean and atmospheric processes. We attract a large number of both male and female undergraduate applicants representing diverse ethnic groups from across the country. Many are multi-discipline majors merging geology, biology, chemistry, or physics with engineering, and/or mathematics and welcome the opportunity to combine their academic training to examine environmental problems. Our goal is a program reflective of today’s world and environmental challenges, one that provides a ‘hands-on’ research experience which illustrates the usefulness of scientific research for understanding real-world problems or phenomena, and one in which students are challenged to apply their academic backgrounds to develop intuition about natural systems and processes. Projects this past summer focused on assessing climate change and its effects on coastal environments and processes. Projects addressed the implications of a changing global climate over the next 50 years on hydrologic cycles and coastal environments like barrier islands and beaches, on seasonal weather conditions and extreme events, on aerosols and the Earth’s radiative balance, and on aquatic habitats and biota. Collaborative field and laboratory or computer-based projects involving two or three REU students, graduate students, and several mentors, enable undergraduate students appreciate the importance of teamwork in addressing specific scientific questions or gaining maximum insight into a particular phenomenon or process. We believe that our approach allows students to understand what their role will be as scientists in the next phase of our earth’s evolution.

This article reports on the study of the components of scientific imagination and describes the scales used to measure scientific imagination in Korean elementary and secondary students. In this study, we developed an inventory, which we call the Scientific Imagination Inventory (SII), in order to examine aspects of scientific imagination. We identified three conceptual components of scientific imagination, which were composed of (1) scientific sensitivity, (2) scientific creativity, and (3) scientific productivity. We administered SII to 662 students (4th-8th grades) and confirmed validity and reliability using exploratory factor analysis and Cronbach α coefficient. The characteristics of Korean elementary and secondary students' overall scientific imagination and difference across gender and grade level are discussed in the results section.

Kowalski, Jennifer R.; Hoops, Geoffrey C.; Johnson, R. Jeremy

2016-01-01

Classroom undergraduate research experiences (CUREs) provide students access to the measurable benefits of undergraduate research experiences (UREs). Herein, we describe the implementation and assessment of a novel model for cohesive CUREs focused on central research themes involving faculty research collaboration across departments. Specifically, we implemented three collaborative CUREs spanning chemical biology, biochemistry, and neurobiology that incorporated faculty members’ research interests and revolved around the central theme of visualizing biological processes like Mycobacterium tuberculosis enzyme activity and neural signaling using fluorescent molecules. Each CURE laboratory involved multiple experimental phases and culminated in novel, open-ended, and reiterative student-driven research projects. Course assessments showed CURE participation increased students’ experimental design skills, attitudes and confidence about research, perceived understanding of the scientific process, and interest in science, technology, engineering, and mathematics disciplines. More than 75% of CURE students also engaged in independent scientific research projects, and faculty CURE contributors saw substantial increases in research productivity, including increased undergraduate student involvement and academic outputs. Our collaborative CUREs demonstrate the advantages of multicourse CUREs for achieving increased faculty research productivity and traditional CURE-associated student learning and attitude gains. Our collaborative CURE design represents a novel CURE model for ongoing laboratory reform that benefits both faculty and students. PMID:27810870

Redesigning a General Education Science Course to Promote Critical Thinking.

Rowe, Matthew P; Gillespie, B Marcus; Harris, Kevin R; Koether, Steven D; Shannon, Li-Jen Y; Rose, Lori A

2015-01-01

Recent studies question the effectiveness of a traditional university curriculum in helping students improve their critical thinking and scientific literacy. We developed an introductory, general education (gen ed) science course to overcome both deficiencies. The course, titled Foundations of Science, differs from most gen ed science offerings in that it is interdisciplinary; emphasizes the nature of science along with, rather than primarily, the findings of science; incorporates case studies, such as the vaccine-autism controversy; teaches the basics of argumentation and logical fallacies; contrasts science with pseudoscience; and addresses psychological factors that might otherwise lead students to reject scientific ideas they find uncomfortable. Using a pretest versus posttest design, we show that students who completed the experimental course significantly improved their critical-thinking skills and were more willing to engage scientific theories the general public finds controversial (e.g., evolution), while students who completed a traditional gen ed science course did not. Our results demonstrate that a gen ed science course emphasizing the process and application of science rather than just scientific facts can lead to improved critical thinking and scientific literacy. © 2015 M.

What Do Students "Construct" According to Constructivism in Science Education?

NASA Astrophysics Data System (ADS)

Bächtold, Manuel

2013-12-01

This paper aims at shedding light on what students can "construct" when they learn science and how this construction process may be supported. Constructivism is a pluralist theory of science education. As a consequence, I support, there are several points of view concerning this construction process. Firstly, I stress that constructivism is rooted in two fields, psychology of cognitive development and epistemology, which leads to two ways of describing the construction process: either as a process of enrichment and/or reorganization of the cognitive structures at the mental level, or as a process of building or development of models or theories at the symbolic level. Secondly, I argue that the usual distinction between "personal constructivism" (PC) and "social constructivism" (SC) originates in a difference of model of reference: the one of PC is Piaget's description of "spontaneous" concepts, assumed to be constructed by students on their own when interacting with their material environment, the one of SC is Vygotsky's description of scientific concepts, assumed to be introduced by the teacher by means of verbal communication. Thirdly, I support the idea that, within SC, there are in fact two trends: one, in line with Piaget's work, demonstrates how cooperation among students affects the development of each individual's cognitive structures; the other, in line with Vygotsky's work, claims that students can understand and master new models only if they are introduced to the scientific culture by their teacher. Fourthly, I draw attention to the process of "problem construction" identified by some French authors. Finally, I advocate for an integrated approach in science education, taking into account all the facets of science learning and teaching mentioned above and emphasizing their differences as well as their interrelations. Some suggestions intended to improve the efficiency of science teaching are made.

Middle-School Science Students' Scientific Modelling Performances Across Content Areas and Within a Learning Progression

NASA Astrophysics Data System (ADS)

Bamberger, Yael M.; Davis, Elizabeth A.

2013-01-01

This paper focuses on students' ability to transfer modelling performances across content areas, taking into consideration their improvement of content knowledge as a result of a model-based instruction. Sixty-five sixth grade students of one science teacher in an urban public school in the Midwestern USA engaged in scientific modelling practices that were incorporated into a curriculum focused on the nature of matter. Concept-process models were embedded in the curriculum, as well as emphasis on meta-modelling knowledge and modelling practices. Pre-post test items that required drawing scientific models of smell, evaporation, and friction were analysed. The level of content understanding was coded and scored, as were the following elements of modelling performance: explanation, comparativeness, abstraction, and labelling. Paired t-tests were conducted to analyse differences in students' pre-post tests scores on content knowledge and on each element of the modelling performances. These are described in terms of the amount of transfer. Students significantly improved in their content knowledge for the smell and the evaporation models, but not for the friction model, which was expected as that topic was not taught during the instruction. However, students significantly improved in some of their modelling performances for all the three models. This improvement serves as evidence that the model-based instruction can help students acquire modelling practices that they can apply in a new content area.

Procedural apprenticeship in school science: Constructivist enabling of connoisseurship

NASA Astrophysics Data System (ADS)

Bencze, J. Lawrence

2000-11-01

In many parts of the world, school science, especially at the secondary school level, is a sort of selection and training camp for future scientists and engineers. For most students, their general lack of cultural capital (Apple, 1990) minimizes their opportunities to survive the rapid coverage of large volumes of abstract, decontextualized laws, theories, and inventions so typical of school science. Most graduates and drop-outs become relatively scientifically and technologically illiterate. They either have forgotten or have confused conceptions of scientific and technological knowledge; often view science and technology as relatively certain, unbiased, and benign with respect to effects on society and the environment; and lack resources necessary to effectively judge products and processes of science and technology or, crucially, to create their own explanations for and changes to phenomena. Citizens with illiteracy to this extent may have little control over their own thoughts and actions and be prey to whims of those who control knowledge, its production and dissemination. Curriculum frameworks are required that enable all students to achieve their maximum potential literacy and, as well, to create their own knowledge, to develop in directions unique to their needs, interests, abilities, and perspectives; that is, to become self-actualized. This latter goal can, in part, be achieved through apprenticeship education in schools, such that students acquire a measure of scientific and technological connoisseurship - expertise enabling them to conduct open-ended scientific investigations and invention projects of their design. In collaboration with five teachers of secondary school science, such a framework was, indeed, developed, and field-tested. Through a spiraling, cyclical process involving synchronous reconstruction of conceptual and procedural understandings, evidence suggests students were able to carry out experiments, studies, and tests of their inventions with minimal teacher involvement. Furthermore, they appeared to accommodate more realistic conceptions of scientific and technological work. Moreover, many seemed to have made progress toward intellectual independence; able to judge knowledge claims independent of authorities. It is hoped that with more schools, systems, and teachers enabling development of such connoisseurship, all students will be better served by school science and, as well, the larger society will be more diverse, adaptable, and free.

The impact of a student-teacher-scientist partnership (STSP) on students' and teachers' content knowledge and attitudes toward science

NASA Astrophysics Data System (ADS)

Houseal, Ana K.

Engaging elementary students in science through inquiry-based methodologies is at the center of science education reform efforts (AAAS, 1989, NRC 1996, 2000). Through scientific problem solving, students can learn that science is more than just learning facts and concepts (NRC, 2000) The process of scientific inquiry, as a way of approaching scientific problem solving, can be taught to students through experiential, authentic (or real-world) science experiences. Student-teacher-scientist partnerships (STSPs) are one vehicle used to connect students to these science experiences with practicing research scientists. However, the literature on STSPs demonstrates they are fraught with challenges and very little is known of their effects on teachers' and students' content knowledge growth or changes in their attitudes about science and scientists. This study addressed these two areas by researching a particular STSP. The STSP, called Students, Teachers, and Rangers and Research Scientists (STaRRS), designed to be incorporated into the existing long-standing education program Expedition: Yellowstone! (E:Y!) was the focus of this study. For teachers, a pre-test, intervention, post-test research design addressing content knowledge gains, attitude changes, and pedagogical changes was used. A quasi-experimental pre- post-test design using treatment and comparison groups of students addressed content knowledge gains and attitude changes. Findings provided evidence of significant positive shifts in teachers' attitudes regarding science and scientists, and trends of shifting pedagogical choices made by teachers. Students showed significant content knowledge gains and an increased positive attitude regarding their perceptions of scientists.

Small-Group Learning in an Upper-Level University Biology Class Enhances Academic Performance and Student Attitudes Toward Group Work

Nakonechny, Joanne; Cragg, Jacquelyn J.; Ramer, Matt S.

2010-01-01

To improve science learning, science educators' teaching tools need to address two major criteria: teaching practice should mirror our current understanding of the learning process; and science teaching should reflect scientific practice. We designed a small-group learning (SGL) model for a fourth year university neurobiology course using these criteria and studied student achievement and attitude in five course sections encompassing the transition from individual work-based to SGL course design. All students completed daily quizzes/assignments involving analysis of scientific data and the development of scientific models. Students in individual work-based (Individualistic) sections usually worked independently on these assignments, whereas SGL students completed assignments in permanent groups of six. SGL students had significantly higher final exam grades than Individualistic students. The transition to the SGL model was marked by a notable increase in 10th percentile exam grade (Individualistic: 47.5%; Initial SGL: 60%; Refined SGL: 65%), suggesting SGL enhanced achievement among the least prepared students. We also studied student achievement on paired quizzes: quizzes were first completed individually and submitted, and then completed as a group and submitted. The group quiz grade was higher than the individual quiz grade of the highest achiever in each group over the term. All students – even term high achievers –could benefit from the SGL environment. Additionally, entrance and exit surveys demonstrated student attitudes toward SGL were more positive at the end of the Refined SGL course. We assert that SGL is uniquely-positioned to promote effective learning in the science classroom. PMID:21209910

To improve science learning, science educators' teaching tools need to address two major criteria: teaching practice should mirror our current understanding of the learning process; and science teaching should reflect scientific practice. We designed a small-group learning (SGL) model for a fourth year university neurobiology course using these criteria and studied student achievement and attitude in five course sections encompassing the transition from individual work-based to SGL course design. All students completed daily quizzes/assignments involving analysis of scientific data and the development of scientific models. Students in individual work-based (Individualistic) sections usually worked independently on these assignments, whereas SGL students completed assignments in permanent groups of six. SGL students had significantly higher final exam grades than Individualistic students. The transition to the SGL model was marked by a notable increase in 10th percentile exam grade (Individualistic: 47.5%; Initial SGL: 60%; Refined SGL: 65%), suggesting SGL enhanced achievement among the least prepared students. We also studied student achievement on paired quizzes: quizzes were first completed individually and submitted, and then completed as a group and submitted. The group quiz grade was higher than the individual quiz grade of the highest achiever in each group over the term. All students--even term high achievers--could benefit from the SGL environment. Additionally, entrance and exit surveys demonstrated student attitudes toward SGL were more positive at the end of the Refined SGL course.

Medical education requires student comprehension of both technical (scientific/medical) and non-technical (general) vocabulary. Our experience with "English as a second language" (ESL) Arab students suggested they often have problems comprehending scientific statements because of weaknesses in their understanding of non-scientific vocabulary. This study aimed to determine whether ESL students have difficulties with general vocabulary that could hinder their understanding of scientific/medical texts. A survey containing English text was given to ESL students in the premedical years of an English-medium medical school in an Arabic country. The survey consisted of sample questions from the Medical College Admission Test (USA). Students were instructed to identify all unknown words in the text. ESL students commenced premedical studies with substantial deficiencies in English vocabulary. Students from English-medium secondary schools had a selective deficiency in scientific/medical terminology which disappeared with time. Students from Arabic-medium secondary schools had equal difficulty with general and scientific/medical vocabulary. Deficiencies in both areas diminished with time but remained even after three years of English-medium higher education. Typically, when teaching technical subjects to ESL students, attention is focused on subject-unique vocabulary and associated modifiers. This study highlights that ESL students also face difficulties with the general vocabulary used to construct statements employing technical words. Such students would benefit from increases in general vocabulary knowledge.

Exposure to science education during college may affect a student's profile, and research experience may be associated with better professional performance. We hypothesized that the impact of research experience obtained during graduate study differs among professional curricula and among graduate courses. A validated multiple-choice questionnaire concerning scientific concepts was given to students in the first and fourth years of medical and law school at a public Brazilian educational institution. Medical students participated more frequently in introductory scientific programs than law students, and this trend increased from the first to the fourth years of study. In both curricula, fourth-year students displayed a higher percentage of correct answers than first-year students. A higher proportion of fourth-year students correctly defined the concepts of scientific hypothesis and scientific theory. In the areas of interpretation and writing of scientific papers, fourth-year students, in both curricula, felt more confident than first-year students. Although medical students felt less confident in planning and conducting research projects than law students, they were more involved in research activities. Medical graduation seems to favor the development of critical scientific maturity than law graduation. Specific policy in medical schools is a reasonable explanation for medical students' participation in more scientific activities.

Bringing Authentic Research into the Classroom with the Mars Student Imaging Project: Comparison of the PBL Gold Standards to the Scientific Methods

2017-04-01

The goal of Project Based Learning (PBL) is to actively engage students through authentic, real word study to increase content knowledge, understanding, and skills for everyday success. The essential design of PBL is very similar in nature to the scientific method and therefore easy to adapt to the science classroom. In my classroom, students use these essential elements when engaging in the study of the processes that affect the surface of a planet such as weathering and erosion. Studying Mars is a hook to getting students to learn about the same processes that occur on Earth and to contrast the differences that occur on another planetary body. As part of the Mars Student Imaging Project (MSIP), students have the opportunity to engage and collaborate with NASA scientists at Arizona State University and get feedback on their work. They research and develop their own question or area of focus to study. They use images of Mars taken using the THEMIS camera onboard the Mars Odyssey Satellite, which has been orbiting Mars since 2001. Students submit a proposal to the scientists at ASU and, if accepted, they are given the opportunity to use the THEMIS camera in orbit to photograph a new region on Mars that will hopefully contribute to their research. Students give a final presentation to the faculty, staff, community, and other students by presenting their work in a poster session and explaining their work to the audience.

Argumentation Key to Communicating Climate Change to the Public

NASA Astrophysics Data System (ADS)

Bleicher, R. E.; Lambert, J. L.

2012-12-01

Argumentation plays an important role in how we communicate climate change science to the public and is a key component integrated throughout the Next Generation Science Standards. A scientific argument can be described as a disagreement between explanations with data being used to justify each position. Argumentation is social process where two or more individuals construct and critique arguments (Kuhn & Udell, 2003; Nussbaum, 1997). Sampson, Grooms, and Walker's (2011) developed a framework for understanding the components of a scientific argument. The three components start with a claim (a conjecture, conclusion, explanation, or an answer to a research question). This claim must fit the evidence (observations that show trends over time, relationships between variables or difference between groups). The evidence must be justified with reasoning (explains how the evidence supports the explanation and whey it should count as support). In a scientific argument, or debate, the controversy focuses on how data were collected, what data can or should be included, and what inferences can be made based on a set of evidence. Toulmin's model (1969) also includes rebutting or presenting an alternative explanation supported by counter evidence and reasoning of why the alternative is not the appropriate explanation for the question of the problem. The process of scientific argumentation should involve the construction and critique of scientific arguments, one that involves the consideration of alternative hypotheses (Lawson, 2003). Scientific literacy depends as much on the ability to refute and recognize poor scientific arguments as much as it does on the ability to present an effective argument based on good scientific data (Osborne, 2010). Argument is, therefore, a core feature of science. When students learn to construct a sound scientific argument, they demonstrate critical thinking and a mastery of the science being taught. To present a convincing argument in support of climate change, students must have a sound foundation in the science underlying it. One place to lay this foundation is in the high school science classroom. For students to gain a good conceptual understanding of climate change science, teachers need a sound understanding of climate change and effective resources to teach it to students. Teacher professional development opportunities are required to provide this background as well as establish collaborative curriculum planning opportunities on the school site (Shulman, 2007). Various strategies for and challenges of implementing argumentation with preservice and practicing teachers will be discussed in this session, as well as ways that argumentation skills can help the broader public evaluate claims of climate skeptics. In the field of argumentation theory, Goodwin (2010) has designed a strategy for developing the ability to make effective scientific arguments. The goal is to establish trust even when there is strong disagreement. At the core, a student fully acknowledges the uncertainty involved in the complex science underlying climate change. This has the effect of establishing some degree of trust. In other words, teachers or students trying to explain climate change to others might be perceived as more trustworthy if they openly declare that there are degrees of uncertainty in different aspects of climate change science (American Meteorological Society, 2011).

However, there was no gender gap in terms of scientific competencies.

Cultivating Citizen Scientists in the Undergraduate Science Classroom

NASA Astrophysics Data System (ADS)

Egger, A. E.

2007-12-01

Several studies indicate a strong correlation between the number of college science courses and science literacy. It is not surprising, then, that the majority of participants in citizen science projects are college graduates who enrolled in at least two science courses. If one goal of citizen science projects is to increase civic science literacy, research suggests that most are preaching to the choir. Attracting a wider audience to citizen science is, therefore, a key challenge. One way to address this challenge is to attract students to enroll and succeed in science courses in college, even if they do not pursue a major in the science, technology, engineering, and mathematics (STEM) disciplines. In fact, only 20% of students receive a degree in STEM, yet virtually all undergraduates are required to take at least one science course. Introductory science courses are therefore critical to cultivating citizen scientists, as they include a large proportion of non- STEM majors. Indeed, a major thrust of recent undergraduate STEM educational reform has been the promotion of 'science for all'. The science for all concept goes beyond recruiting students into the STEM disciplines to promoting a level of scientific literacy necessary to make informed decisions. A clear implication of this inclusive attitude is the need to redesign introductory science courses to make them accessible and explicitly related to scientific literacy. This does not mean dumbing down courses; on the contrary, it means engaging students in real scientific investigations and incorporating explicit teaching about the process of science, thus fostering a lifelong appreciation for (and, hopefully, participation in) science. Unfortunately, many students enter college with minimal understanding of the process of science. And when they arrive in their introductory classes, science is presented to them as a system of facts to be memorized - comparable to memorizing a poem in a foreign language without understanding the vocabulary. New resources available through the Visionlearning project (http://www.visionlearning.com) provide the means to incorporate teaching about the process of science into disciplinary content, thus facilitating the reform the way that undergraduate students are taught science at the introductory level. This kind of educational reform may be a long-term approach to developing citizen scientists, but research from several different disciplines and perspectives suggests it is a critical step in building scientific literacy and lifelong participation in science.

Rocks, Landforms, and Landscapes vs. Words, Sentences, and Paragraphs: An Interdisciplinary Team Approach to Teaching the Tie Between Scientific Literacy and Inquiry-based Writing in a Community College's Geoscience Program and a University's' Geoscience Program

Scientific literacy and inquiry-based writing go together like a hand and glove. Science literacy, defined by NRC in The NSF Standards, stresses the relationship between knowledge of science and skill in literacy so "a person can ask, find, or determine answers to questions derived from curiosity about everyday experiences. It means that a person has the ability to describe, explain, and predict natural phenomena. Scientific literacy entails being able to read with understanding articles about science in the popular press and to engage in social conversation about the validity of the conclusions. Scientific literacy implies that a person can identify scientific issues underlying national and local decisions and express positions that are scientifically and technologically informed." A growing body of research and practice in science instruction suggests language is essential in the practice of the geosciences. Writing and critical thinking are iterative processes. We use this approach to educate our geoscience students to learn, write, and think critically. One does not become an accomplished writer via one course. Proficiency is gained through continued exposure, guidance and tailored assignments. Inquiry-based geoscience makes students proficient in the tools of the geosciences and to develop explanations to questions about Earth events. We have scaffolded our courses from introductory geology, English composition, writing in the geosciences, introduction to field methods and report writing to do more critical thinking, research data gatherings, and in-depth analysis and synthesis. These learning experiences that encourage students to compare their reasoning models, communicate verbally, written and graphically. The English composition course sets the stage for creative assignments through formulation of original research questions, collection of primary data, analysis, and construction of written research papers. Proper use of language allows students to clarify their ideas, make claims, present arguments, and record and present findings. Students have acquired the skills to be considered scientifically literate and capable of learning. A poster demonstrating the tie between Scientific Literacy and Inquiry-Based Writing has been produced and distributed widely around campus.

Oceans of Data: In what ways can learning research inform the development of electronic interfaces and tools for use by students accessing large scientific databases?

2012-12-01

The practice of science and engineering is being revolutionized by the development of cyberinfrastructure for accessing near real-time and archived observatory data. Large cyberinfrastructure projects have the potential to transform the way science is taught in high school classrooms, making enormous quantities of scientific data available, giving students opportunities to analyze and draw conclusions from many kinds of complex data, and providing students with experiences using state-of-the-art resources and techniques for scientific investigations. However, online interfaces to scientific data are built by scientists for scientists, and their design can significantly impede broad use by novices. Knowledge relevant to the design of student interfaces to complex scientific databases is broadly dispersed among disciplines ranging from cognitive science to computer science and cartography and is not easily accessible to designers of educational interfaces. To inform efforts at bridging scientific cyberinfrastructure to the high school classroom, Education Development Center, Inc. and the Scripps Institution of Oceanography conducted an NSF-funded 2-year interdisciplinary review of literature and expert opinion pertinent to making interfaces to large scientific databases accessible to and usable by precollege learners and their teachers. Project findings are grounded in the fundamentals of Cognitive Load Theory, Visual Perception, Schemata formation and Universal Design for Learning. The Knowledge Status Report (KSR) presents cross-cutting and visualization-specific guidelines that highlight how interface design features can address/ ameliorate challenges novice high school students face as they navigate complex databases to find data, and construct and look for patterns in maps, graphs, animations and other data visualizations. The guidelines present ways to make scientific databases more broadly accessible by: 1) adjusting the cognitive load imposed by the user interface and visualizations so that it doesn't exceed the amount of information the learner can actively process; 2) drawing attention to important features and patterns; and 3) enabling customization of visualizations and tools to meet the needs of diverse learners.

PolarTREC (Teachers and Researchers Exploring and Collaborating) is a National Science Foundation (NSF) funded program in which K-12 teachers participate in hands-on field research experiences in the polar regions. PolarTREC highlights the importance of involving teachers in scientific research in regards to their careers as educators and their ability to engage students in the direct experience of science. To date, PolarTREC has placed over 90 teachers with research teams in the Arctic and Antarctic. Published results of our program evaluation quantify the effect of the field experience on the teachers' use of the real scientific process in the classroom, the improvement in science content taught in classrooms, and the use of non-fiction texts (real data and science papers) as primary learning tools for students. Teachers and students both report an increase of STEM literacy in the classroom content, confidence in science education, as well as a markedly broadened outlook of science as essential to their future. Research conducted with science teams affirms that they are achieving broader impacts when PolarTREC teachers are involved in their expeditions. Additionally, they reported that these teachers making vital contributions to the success of the scientific project.

Integrating high school and college students into the astronomy research community of practice through participation in a hybrid research seminar.

Freed, R.

2016-12-01

The Institute for Student Astronomical Research over the past two years has provided dozens of high school and college students the opportunity to conduct original research in astronomy and to publish their work in peer-reviewed journals. Students are engaged in the entire scientific process from coming up with a research question to collecting and analyzing the data and writing up their results for publication. During the process students work with amateur and/or professional astronomers to learn how to conduct their research and communicate their findings effectively. Working within a community of practice has been shown to improve student learning and the Institute for Student Astronomical Research provides a framework in which to bring students and astronomers together while allowing for the work to be done in a student-centered fashion.

SEAS: Student Experiments At Sea - An Education Outreach Pilot Program Sponsored by the Ridge2000 Program

NASA Astrophysics Data System (ADS)

Goehring, L.

2004-12-01

SEAS is a pilot program for middle and high school students who want to learn science by doing science. SEAS students study the deep sea hydrothermal vent environment and learn to ask questions about this exciting, relatively unexplored world, just as researchers do. SEAS students also learn how to answer their own questions through the process of scientific investigation. With the SEAS program, students have the opportunity to participate in the actual discovery process, along side deep-sea researchers. SEAS builds upon the successes of programs like Dive&Discover and Extreme2000, which demonstrated the capability deep-sea scientists have in engaging students with live research. SEAS extends this concept by inviting students to participate in deep-sea research through formal proposal and report competitions. SEAS challenges students to higher levels of achievement. A curriculum, developed by teachers expert in the translation of scientific inquiry in the classroom, prepares students to participate. SEAS was concept-tested during the 2003-2004 school year, with 14 pilot teachers and approximately 800 students. Twenty Ridge2000 scientists contributed their time and expertise to the SEAS program in its first year. Five student proposals were selected and conducted at sea in April during a Ridge2000 research cruise to the East Pacific Rise. All results were posted to the SEAS website (http://www.ridge2000.org/SEAS/) during the cruise, and students were invited to analyze data for their final reports. Final student reports, along with scientists comments were also posted. During the 2004-2005 school year, SEAS will be evaluated for its impact on student learning and attitudes toward science. The benefits of SEAS to the Ridge2000 scientific community are many. Scientists are invited to contribute in a variety of ways, all of which help satisfy the requirement of NSFs Broader Impacts Criterion. They may contribute time and expertise by answering student questions and reviewing student proposals and reports. They may choose to host the student research on their cruise. By sharing the load, no one scientist is burdened, nor expected to contribute additional funding. The Ridge2000 Program oversees the development, execution and dissemination of SEAS, helping make outreach efficient and easy for scientists.

Guiding students towards sensemaking: teacher questions focused on integrating scientific practices with science content

NASA Astrophysics Data System (ADS)

Benedict-Chambers, Amanda; Kademian, Sylvie M.; Davis, Elizabeth A.; Palincsar, Annemarie Sullivan

2017-10-01

Science education reforms articulate a vision of ambitious science teaching where teachers engage students in sensemaking discussions and emphasise the integration of scientific practices with science content. Learning to teach in this way is complex, and there are few examples of sensemaking discussions in schools where textbook lessons and teacher-directed discussions are the norm. The purpose of this study was to characterise the questioning practices of an experienced teacher who taught a curricular unit enhanced with educative features that emphasised students' engagement in scientific practices integrated with science content. Analyses indicated the teacher asked four types of questions: explication questions, explanation questions, science concept questions, and scientific practice questions, and she used three questioning patterns including: (1) focusing students on scientific practices, which involved a sequence of questions to turn students back to the scientific practice; (2) supporting students in naming observed phenomena, which involved a sequence of questions to help students use scientific language; and (3) guiding students in sensemaking, which involved a sequence of questions to help students learn about scientific practices, describe evidence, and develop explanations. Although many of the discussions in this study were not yet student-centred, they provide an image of a teacher asking specific questions that move students towards reform-oriented instruction. Implications for classroom practice are discussed and recommendations for future research are provided.

Introducing Interactive Teaching Styles into Astronomy Lectures

NASA Astrophysics Data System (ADS)

Deming, G. L.

1997-12-01

The majority of undergraduate students who take an astronomy class are non-science majors attempting to satisfy a science requirement. Often in these "scientific literacy" courses, facts are memorized for the exam and forgotten shortly afterwards. Scientific literacy courses should advance student skills toward processing information and applying higher order thinking rather than simple recall and memorization of facts. Thinking about material as it is presented, applying new knowledge to solve problems, and thinking critically about topics are objectives that many astronomy instructors hope their students are achieving. A course in astronomy is more likely to achieve such goals if students routinely participate in their learning. Interactive techniques can be quite effective even in large classes. Examples of activities are presented that involve using cooperative learning techniques, writing individual and group "minute papers," identifying and correcting misconceptions, including the whole class in a demonstration, and applying knowledge to new situations.

An Exploration of High School (12 17 Year Old) Students' Understandings of, and Attitudes Towards Biotechnology Processes

NASA Astrophysics Data System (ADS)

Dawson, Vaille

2007-03-01

The products of modern biotechnology processes such as genetic engineering, DNA testing and cloning will increasingly impact on society. It is essential that young people have a well-developed scientific understanding of biotechnology and associated processes so that they are able to contribute to public debate and make informed personal decisions. The aim of this study was to examine the development of understandings and attitudes about biotechnology processes as students progress through high school. In a cross-sectional case study, data was obtained from student interviews and written surveys of students aged 12 to 17 years. The results indicate that students' ability to provide a generally accepted definition and examples of biotechnology, cloning and genetically modified foods was relatively poor amongst 12 13 year old students but improved in older students. Most students approved of the use of biotechnology processes involving micro-organisms, plants and humans and disapproved of the use of animals. Overall, 12 13 year old students' attitudes were less favourable than older students regardless of the context. An awareness of the development and range of students' understandings and attitudes may lead to a more appropriate use of biotechnology curriculum materials and thus improved biotechnology education in schools.

Students' abilities to critique scientific evidence when reading and writing scientific arguments

NASA Astrophysics Data System (ADS)

Knight, Amanda M.

Scientific arguments are used to persuade others for explanations that make sense of the natural world. Over time, through the accumulation of evidence, one explanation for a scientific phenomenon tends to take precedence. In science education, arguments make students' thinking and reasoning visible while also supporting the development of their conceptual, procedural, and epistemic knowledge. As such, argumentation has become a goal within recent policy documents, including the Next Generation Science Standards, which, in turn, presents a need for comprehensive, effective, and scalable assessments. This dissertation used assessments that measure students' abilities to critique scientific evidence, which is measured in terms of the form of justification and the support of empirical evidence, when reading and writing scientific arguments. Cognitive interviews were then conducted with a subset of the students to explore the criteria they used to critique scientific evidence. Specifically, the research investigated what characteristics of scientific evidence the students preferred, how they critiqued both forms of justification and empirical evidence, and whether the four constructs represented four separate abilities. Findings suggest that students' prioritized the type of empirical evidence to the form of justification, and most often selected relevant-supporting justifications. When writing scientific arguments, most students constructed a justified claim, but struggled to justify their claims with empirical evidence. In comparison, when reading scientific arguments, students had trouble locating a justification when it was not empirical data. Additionally, it was more difficult for students to critique than identify or locate empirical evidence, and it was more difficult for students to identify than locate empirical evidence. Findings from the cognitive interviews suggest that students with more specific criteria tended to have more knowledge of the construct. Lastly, dimensional analyses suggest that these may not be four distinct constructs, which has important implications for curriculum development and instructional practice. Namely, teachers should attend to the critique of scientific evidence separately when reading and writing scientific arguments.

Serious games for Geophysics

Childhood stage is indispensable in the education of human beings and especially critical to arise scientific interest in children. We discuss the participatory design of a didactic videogame, i.e. a "serious" game to teach geophysics and Earth sciences to high and low-school students. Geophysics is the application of the laws and techniques of physics to uncover knowledge about the earth's dynamic processes and subsurface structure. It explores phenomena such as earthquakes, volcanoes, tsunamis to improve our understanding of the earth's physical processes and our ability to predict reoccurrences. Effective mitigation of risks from catastrophic geologic hazards requires knowledge and understanding of local geology and geologic processes. Scientific outreach can be defined as discourse activity, whose main objective is to communicate some knowledge previously produced in scientific contexts to a non-expert massive audience. One of the difficulties science educators need to overcome is to explain specific concepts from a given discipline in a language simple and understandable for their audience. Digital games today play a large role in young people's lives. Games are directly connected to the life of today's adolescents. Therefore, digital games should be included and broached as a subject in the classroom. The ardor and enthusiasm that digital games evoke in teenagers has indeed brought many researchers, school leaders and teachers to the question "how video games" can be used to engage young people and support their learning inside the classroom. Additionally, studies have shown that digital games can enhance various skills such as the ability to concentrate, stamina, tactical aptness, anticipatory thinking, orientation in virtual spaces, and deductive reasoning. Thus, videogames become an effective didactic mechanism and should have a place in the classroom. The project aims to explore the potentials of entertainment technologies in educational processes; contribute to innovative pedagogies for scientific learning; create a scientific feedback-loop with students and teachers; implement a multi-level video game for scientific outreach.

A model of reading comprehension focuses on eye fixations, which are related to the level of reading processes--words, clauses, and text units. Longer pauses are associated with greater processing difficulty. This model is illustrated for a group of undergraduate students reading scientific articles from "Newsweek" and "Time" magazines.

In this laboratory exercise, students were taught concepts of microbiology and scientific process through an everyday activity — cosmetic use. The students’ goals for the lab were to develop a hypothesis regarding microbial contamination in cosmetics, learn techniques to culture and differentiate microorganisms from cosmetics, and propose best practices in cosmetics use based on their findings. Prior to the lab, students took a pretest to assess their knowledge of scientific hypotheses, microbiology, and cosmetic safety. In the first week, students were introduced to microbiological concepts and methodologies, and cosmetic terminology and safety. Students completed a hypothesis-writing exercise before formulating and testing their own hypotheses regarding cosmetic contamination. Students provided a cosmetic of their own and, in consultation with their lab group, chose one product for testing. Samples were serially diluted and plated on a variety of selective media. In the second week, students analyzed their plates to determine the presence and diversity of microbes and if their hypotheses were supported. Students completed a worksheet of their results and were given a posttest to assess their knowledge. Average test scores improved from 5.2 (pretest) to 7.8 (posttest), with p-values < 0.0001. Seventy-nine percent (79%) of students correctly identified hypotheses that were not falsifiable or lacked variables, and 89% of students improved their scores on questions concerning safe cosmetic use. Ninety-one percent (91%) of students demonstrated increased knowledge of microbial concepts and methods. Based on our results, this lab is an easy, yet effective, way to enhance knowledge of scientific concepts for nonmajors, while maintaining relevance to everyday life. PMID:23653761

Yes, High School Students Can Analyze Chandra Data

2002-12-01

For the past two years, high school students at the North Carolina School of Science and Math (NCSSM) have worked with new and archival Chandra data, and have produced interesting scientific results. These results have included one refereed paper in the Ap.J., and about a dozen presentations at scientific meetings (including three at this meeting). The students were selected, based on interest, from the junior class at NCSSM, to stay on campus and work intensively for 2 to 4 weeks over the summer. Each team of students selected an object with public Chandra ACIS data, and were taught how to produce data products such as images and spectra, as well as conduct a literature search. In most cases, a paper had already been published using those data, and the students were usually able to reproduce the results. As the students waded through the literature, they would search for a theory to test or an interesting new phenomenon. Often the students would request an image in another wavelength to compare in detail to the Chandra data. After the summer, many students continued to work throughout the following fall semester, producing a paper for submission to the Siemens Westinghouse Science and Technology Competition by the beginning of October. In the process of conducting research, the students learn to apply many physics concepts, and learn valuable scientific research and writing skills. Those students that choose to continue with astrophysics can often dive directly into a high-level research project immediately when they arrive at college. These programs have been funded by NASA, through E/PO grants attached to parent research grants.

Salt, time, and metaphor: examining norms in scientific culture

NASA Astrophysics Data System (ADS)

Brady, Anna G.

2017-06-01

As has been widely discussed, the National Research Council's (NRC) current policy in United States education advocates supporting students toward acquiring skills to engage in scientific practices. NRC policy also suggests that supporting students in the practices of science may require different approaches than what is required for supporting student engagement with scientific content. Further, acquiring skills in scientific practices is not limited to gaining proficiency in utilizing tools that support scientific inquiry: students must also understand how to interpret information generated from such tools. These tools of scientific practices are embedded within scientific culture, which from Sewell's perspective, is comprised of both practice and semiotic code (symbols and meanings). To become scientifically literate students must learn to utilize this code in practice. Author Germà Garcia-Belmonte identified one example of learning to utilize the semiotic code in scientific practice and considers challenges faced by undergraduate physics and engineering students within that context. Garcia-Belmonte observes students struggle to interpret symbols and meaning (the visual display generated) while engaging in practice (utilizing an oscilloscope) and posits that two, culturally bound, competing, linguistic metaphors of time may be the cause. Ultimately, however, the author does not explore beyond hypotheses. Although his theory may be correct, the paper serves as a reminder of the responsibility we have to students. As educators, it is useful and beneficial to make observations and develop theories surrounding why our students struggle. However, in addition to theorizing on why, for example, a particular scientific norm might present challenges for our students, we must remain mindful that challenges may not be uniform and may vary considerably according to students' culture(s). Engaging with students and soliciting specific information regarding the challenges they face allows us, as educators, to both examine whether students' reported challenges align or conflict with our own perceptions of those challenges, and subsequently devise and test methods toward supporting students in overcoming their challenges.

Stimulating Scientific Reasoning with Drawing-Based Modeling

Heijnes, Dewi; van Joolingen, Wouter; Leenaars, Frank

2018-02-01

We investigate the way students' reasoning about evolution can be supported by drawing-based modeling. We modified the drawing-based modeling tool SimSketch to allow for modeling evolutionary processes. In three iterations of development and testing, students in lower secondary education worked on creating an evolutionary model. After each iteration, the user interface and instructions were adjusted based on students' remarks and the teacher's observations. Students' conversations were analyzed on reasoning complexity as a measurement of efficacy of the modeling tool and the instructions. These findings were also used to compose a set of recommendations for teachers and curriculum designers for using and constructing models in the classroom. Our findings suggest that to stimulate scientific reasoning in students working with a drawing-based modeling, tool instruction about the tool and the domain should be integrated. In creating models, a sufficient level of scaffolding is necessary. Without appropriate scaffolds, students are not able to create the model. With scaffolding that is too high, students may show reasoning that incorrectly assigns external causes to behavior in the model.

Exploring scientific creativity of eleventh-grade students in Taiwan

Liang, Jia-Chi

2002-04-01

Although most researchers focus on scientists' creativity, students' scientific creativity should be considered, especially for high school and college students. It is generally assumed that most professional creators in science emerge from amateur creators. Therefore, the purpose of this study is to investigate the relationship between students' scientific creativity and selected variables including creativity, problem finding, formulating hypotheses, science achievement, the nature of science, and attitudes toward science for finding significant predictors of eleventh grade students' scientific creativity. A total of 130 male eleventh-grade students in three biology classes participated in this study. The main instruments included the Test of Divergent Thinking (TDT) for creativity measurement, the Creativity Rating Scale (CRS) and the Creative Activities and Accomplishments Check Lists (CAACL ) for measurement of scientific creativity, the Nature of Scientific Knowledge Scale (NSKS) for measurement of the nature of science, and the Science Attitude Inventory II (SAI II) for measurement of attitudes toward science. In addition, two instruments on measuring students' abilities of problem finding and abilities of formulating hypotheses were developed by the researcher in this study. Data analysis involved descriptive statistics, Pearson product-moment correlations, and stepwise multiple regressions. The major findings suggested the following: (1) students' scientific creativity significantly correlated with some of selected variables such as attitudes toward science, problem finding, formulating hypotheses, the nature of science, resistance to closure, originality, and elaboration; (2) four significant predictors including attitudes toward science, problem finding, resistance to closure, and originality accounted for 48% of the variance of students' scientific creativity; (3) there were big differences between students with a higher and a lower degree of scientific creativity on the variables of family support, career images, and readings about science; and (4) many students were confused about the creative and moral levels on NSKS and the concept of "almighty of science" and purposes of science on SAI II. The results of this study may provide a more holistic and integrative interpretation of students' scientific creativity and propose better ways of evaluating students' scientific creativity. In addition, the research results may encourage teachers to view scientific creativity as an ability that can be enhanced through various means in classroom science teaching.

Eliciting Taiwanese high school students' scientific ontological and epistemic beliefs

Lin, Tzung-Jin; Tsai, Chin-Chung

2017-11-01

This study employed the interview method to clarify the underlying dimensions of and relationships between students' scientific ontological and epistemic beliefs. Forty Taiwanese high school students were invited to participate in this study. Through content analysis of the participants' interview responses two ontological dimensions including 'status of nature' and 'structure of nature' were identified and found to be associated with each other. The two epistemic dimensions 'knowledge' and 'knowing' aligned with past literature were also categorised. Besides five pattern variations in terms of the aforementioned four dimensions were recognised based on the students' philosophical stances on their scientific ontological and epistemic beliefs. According to the Chi-square test results both dimensions of scientific ontological beliefs were significantly related to the two dimensions of scientific epistemic beliefs respectively. In general the students who endorsed a more sophisticated ontological stance regarding the status and structure of nature tended to express a more mature epistemic stance toward scientific knowledge and ways of knowing. The results suggest that the maturation of students' scientific epistemic beliefs may serve as a precursor and the fundamental step in promoting the sophistication of students' scientific ontological beliefs.

Constructing Scientific Explanations: a System of Analysis for Students' Explanations

de Andrade, Vanessa; Freire, Sofia; Baptista, Mónica

2017-08-01

This article describes a system of analysis aimed at characterizing students' scientific explanations. Science education literature and reform documents have been highlighting the importance of scientific explanations for students' conceptual understanding and for their understanding of the nature of scientific knowledge. Nevertheless, and despite general agreement regarding the potential of having students construct their own explanations, a consensual notion of scientific explanation has still not been reached. As a result, within science education literature, there are several frameworks defining scientific explanations, with different foci as well as different notions of what accounts as a good explanation. Considering this, and based on a more ample project, we developed a system of analysis to characterize students' explanations. It was conceptualized and developed based on theories and models of scientific explanations, science education literature, and from examples of students' explanations collected by an open-ended questionnaire. With this paper, it is our goal to present the system of analysis, illustrating it with specific examples of students' collected explanations. In addition, we expect to point out its adequacy and utility for analyzing and characterizing students' scientific explanations as well as for tracing their progression.

2018-05-01

The purposes of this study were to investigate students’ learning progression on reading activity, science concept comprehension and how they imply it in scientific communication in the classroom. Fifty-nine biology education students participated in this study. This classroom research was developed to portray students’ reading activity, factors affecting reading comprehension, and the development of reading motivation. Qualitative analysis was used to describe the whole activities, involve the instruction, process and the product of reading activity. The result concluded that each student has their own way in interpreting the information from scientific text, but generally, they can filter and apply it in their argument as a part of reasoning and evidence. The findings can be used to direct reading activity to the goal of inquiry in order to support the nature of reading as evidence.

Scientific literacy is considered as a benchmark of high and low quality of science education in a country. Teachers as a major component of learning at the forefront of building science literacy skills of students in the class. The primary purpose this study is development science teacher coaching model based on scientific literacy. In this article we describe about teacher science literacy and profile coaching model for science’ teachers based on scientific literacy which a part of study conducted in first year. The instrument used in this study consisted of tests, observation sheet, interview guides. The finding showed that problem of low scientific literacy is not only happen the students, but science’ teachers which is a major component in the learning process is still not satisfactory. Understanding science teacher is strongly associated with the background disciplinary. Science teacher was still weak when explaining scientific phenomena, mainly related to the material that relates to the concept of environmental. Coaching model generated from this study consisted of 8 stages by assuming the teacher is an independent learner, so the coaching is done with methods on and off, with time off for activities designed more.

Undergraduate students struggle to read the scientific literature and educators have suggested that this may reflect deficiencies in their science literacy skills. In this two-year study we develop and test a strategy for using the scientific literature to teach science literacy skills to novice life science majors. The first year of the project served as a preliminary investigation in which we evaluated student science literacy skills, created a set of science literacy learning objectives aligned with Bloom’s taxonomy, and developed a set of homework assignments that used peer-reviewed articles to teach science literacy. In the second year of the project the effectiveness of the assignments and the learning objectives were evaluated. Summative student learning was evaluated in the second year on a final exam. The mean score was 83.5% (±20.3%) and there were significant learning gains (p < 0.05) in seven of nine of science literacy skills. Project data indicated that even though students achieved course-targeted lower-order science literacy objectives, many were deficient in higher-order literacy skills. Results of this project suggest that building scientific literacy is a continuing process which begins in first-year science courses with a set of fundamental skills that can serve the progressive development of literacy skills throughout the undergraduate curriculum.

Translanguaging in a middle school science classroom: Constructing scientific arguments in English and Spanish

NASA Astrophysics Data System (ADS)

Licona, Peter R.

This dissertation investigates translanguaging in an English/Spanish dual language middle school science classroom as the teacher and students worked through a curriculum unit focusing on socioscientific issues and implementing a scientific argumentation framework. Translanguaging is the process in which bilingual speakers fluidly and dynamically draw from their full linguistic repertoire to perform a communicative act. Using ethnographically informed data collection in conjunction with discourse analysis, teacher translanguaging was examined for its related functions in the science classroom and how teacher translanguaging afforded opportunities for framing and supporting scientific argumentation. Results suggest that the functions of teacher translanguaging fell into three main themes: maintaining classroom culture, facilitating the academic task, and framing epistemic practices. Of the three categories of translanguaging, framing epistemic practices proved to be of paramount importance in the teacher presenting and supporting the practice of scientific argumentation. Implications from this study are relevant for pre-service science teacher preparation and in-service science teacher professional development for teachers working with emergent bilingual students.

Using Scientific Visualizations to Enhance Scientific Thinking In K-12 Geoscience Education

NASA Astrophysics Data System (ADS)

Robeck, E.

2016-12-01

The same scientific visualizations, animations, and images that are powerful tools for geoscientists can serve an important role in K-12 geoscience education by encouraging students to communicate in ways that help them develop habits of thought that are similar to those used by scientists. Resources such as those created by NASA's Scientific Visualization Studio (SVS), which are intended to inform researchers and the public about NASA missions, can be used in classrooms to promote thoughtful, engaged learning. Instructional materials that make use of those visualizations have been developed and are being used in K-12 classrooms in ways that demonstrate the vitality of the geosciences. For example, the Center for Geoscience and Society at the American Geosciences Institute (AGI) helped to develop a publication that outlines an inquiry-based approach to introducing students to the interpretation of scientific visualizations, even when they have had little to no prior experience with such media. To facilitate these uses, the SVS team worked with Center staff and others to adapt the visualizations, primarily by removing most of the labels and annotations. Engaging with these visually compelling resources serves as an invitation for students to ask questions, interpret data, draw conclusions, and make use of other processes that are key components of scientific thought. This presentation will share specific resources for K-12 teaching (all of which are available online, from NASA, and/or from AGI), as well as the instructional principles that they incorporate.

The Role of Interdisciplinary GIS and Data Curation Librarians in Enhancing Authentic Scientific Research in the Classroom

NASA Astrophysics Data System (ADS)

Branch, B. D.; Fosmire, M.

2012-12-01

Data science is a recently evolved area of scientific inquiry, where data, often collected by others, is analyzed by independent investigators to draw new conclusions. As such, data literacy needs to be incorporated into authentic research activities. The earth sciences in particular have a trove of data that resides in national data centers as well as individual investigators' labs, which can be repurposed to provide the inputs for students to make their own inquiries into the data. With the amount of data available, students can make more substantive conclusions than if relying just on data they've collected themselves. A new scientific role is that of the data scientist or data curation specialist. This person understands best practices in data and knowledge management and can translate those skills into an environment appropriate for K-20 students and teachers. In particular, data curation specialists can transform raw data into data that is audience appropriate that can be re-used. First, appropriate research data can be located, as well as foundational or baseline data (topography, political maps, etc.), and that data needs to be converted (or directions for conversion supplied) so that it can be ingested into the processing system used for the activity. Furthermore, data needs to be organized, especially as it is processed by students, and multiple versions of data created. Data also should be appropriately annotated to allow for effective sharing among students and determining reproducibility of the data. Finally, appropriate visualization of the data can be facilitated by a data curation specialist. To provide a concrete example, one of the authors developed, a data-driven authentic research project for a group of middle school students looking at water quality in a North Carolina community. Students needed to find relevant hydrologic, environmental, and political data as inputs for their project. They then collected local data to add to the standard data, so they could build a profile of water quality over time. Once the data had been appropriately collected, processed, and added, students could then develop queries to run against the data to evaluate their research questions. Simple statistical analysis was then run to determine the validity of their conclusions, and finally, presentations were developed to explain their results. Furthermore, students were empowered to connect the results of the research project to suggest policy changes for their community.

Fostering radical conceptual change through dual-situated learning model

NASA Astrophysics Data System (ADS)

She, Hsiao-Ching

2004-02-01

This article examines how the Dual-Situated Learning Model (DSLM) facilitates a radical change of concepts that involve the understanding of matter, process, and hierarchical attributes. The DSLM requires knowledge of students' prior beliefs of science concepts and the nature of these concepts. In addition, DSLM also serves two functions: it creates dissonance with students' prior knowledge by challenging their epistemological and ontological beliefs about science concepts, and it provides essential mental sets for students to reconstruct a more scientific view of the concepts. In this study, the concept heat transfer: heat conduction and convection, which requires an understanding of matter, process, and hierarchical attributes, was chosen to examine how DSLM can facilitate radical conceptual change among students. Results show that DSLM has great potential to foster a radical conceptual change process in learning heat transfer. Radical conceptual change can definitely be achieved and does not necessarily involve a slow or gradual process.

What Makes a Scientific Research Question Worth Investigating? Students' Epistemic Criteria and Considerations of Contribution

NASA Astrophysics Data System (ADS)

Berson, Eric Bruckner

This dissertation introduces the construct of worthwhileness as an important aspect of students' practical epistemologies of science (Sandoval, 2005). Specifically, it examines how students conceptualize what makes a scientific research question worthwhile, through a close analysis of the criteria they use for evaluating scientific research questions. Elementary (n=21) and high school students (n=21) participated in this study. As part of semi-structured interviews, students engaged in three novel tasks designed to elicit the epistemic criteria they use to evaluate scientific research questions in a variety of contexts. Findings indicate that elementary and high school students alike could engage in the practice of evaluating the worth of scientific questions. The criteria they employed included degree of interest, difficulty, and the contribution of questions to knowledge or to solving a problem. The criteria students considered varied by context. Several key differences emerged between the reasoning of the two grade cohorts. High school students tended to place more weight on the contribution of the research question. Also, the criteria reflected in the high school students' judgments of the scientific value of individual questions more closely accorded with the criteria they identified retrospectively as the basis of their judgments. Furthermore, the older cohort more often rationalized the selection and sequence of research questions within a single domain on the basis of epistemic contingency between questions. How students conceptualize what makes a scientific research question worthwhile constitutes a key aspect of students' epistemic reasoning. It is particularly important to understand how students judge the worthwhilness of scientific research questions given the central epistemic role of research questions in scientific inquiry.

Science Olympiad students' nature of science understandings

NASA Astrophysics Data System (ADS)

Philpot, Cindy J.

2007-12-01

Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws. High level science classes and participation in Science Olympiad did not translate into informed understandings of NOS. There were implications that labs with a set procedure and given data tables did not contribute to informed NOS understandings, while explicit instruction may have contributed to more informed understandings. Exploring these high achieving, Science Olympiad students' understandings of NOS was a crucial step to understanding what experiences formed these students' understandings so that teachers may better their practices and help more students succeed in becoming scientifically literate citizens.

The ultimate goal of learning in the curriculum 2013 is that learning must improve and balance between soft skills and hard skills of learners. In addition to the knowledge aspect, one of the other skills to be trained in the learning process using a scientific approach is communication skills. This study aims to get an overview of the implementation of interactive conceptual instruction with multi representation to optimize the achievement of students’ scientific communication skills on work and energy concept. The scientific communication skills contains the sub-skills were searching the information, scientific writing, group discussion and knowledge presentation. This study was descriptive research with observation method. Subjects in this study were 35 students of class X in Senior High School at Sumedang. The results indicate an achievement of optimal scientific communication skills. The greatest achievement of KKI based on observation is at fourth meeting of KKI-3, which is a sub-skill of resume writing of 89%. Allmost students responded positively to the implication of interactive conceptual instruction with multi representation approach. It can be concluded that the implication of interactive conceptual instruction with multi representation approach can optimize the achievement of students’ scientific communication skill on work and energy concept.

Current reforms in science education place increasing demands on teachers and students to engage not only with scientific content but also to develop an understanding of the nature of scientific inquiry (AAAS, 1993; NRC, 1996). Teachers are expected to engage students with authentic scientific practices including posing questions, conducting observations, analyzing data, developing explanations and arguing about them using evidence. This charge is challenging for many reasons most notably the difficulty in obtaining meaningful data about complex scientific phenomena that can be used to address relevant scientific questions that are interesting and understandable to K-12 students. We believe that ocean sciences provide an excellent context for fostering scientific inquiry in the classroom. Of particular interest are the technological and scientific advances of Ocean Observing Systems, which allow scientists to continuously interact with instruments, facilities, and other scientists to explore the earth-ocean- atmosphere system remotely. Oceanographers are making long-term measurements that can also resolve episodic oceanic processes on a wide range of spatial and temporal scales crucial to resolving scientific questions related to Earth's climate, geodynamics, and marine ecosystems. The availability of a diverse array of large data sets that are easily accessible provides a unique opportunity to develop inquiry-based learning environments in which students can explore many important questions that reflect current research trends in ocean sciences. In addition, due to the interdisciplinary nature of the ocean sciences these data sets can be used to examine ocean phenomena from a chemical, physical, or biological perspective; making them particularly useful for science teaching across the disciplines. In this session we will describe some of the efforts of the Centers for Ocean Sciences Education Excellence- Mid Atlantic (COSEE MA) to develop instructional materials, in which students use real-time-data (RTD) to generate explanations about important ocean phenomena. We will discuss our use of an Instructional Design Model (Gauge 1987) to: 1) assess our audience need, 2) develop an effective collaborative design team, 3) develop and evaluate the instructional product, and 4) implement professional development designed to familiarize teachers with oceans sciences as a context for scientific inquiry.

A curriculum was designed to shape biomedical graduate students into researchers with a high commitment to professionalism and social responsibility, and to provide students with tools to navigate the complex, rapidly evolving academic and societal environments with a strong ethical commitment. Problem-Based Learning (PBL) pedagogy was chosen because it is active, learner-centered, and focuses on skill and process development. Additionally, the small group format provides a high degree of socialization around professional norms. Two courses were developed. Scientific Professionalism Scientific Integrity addressed discipline-specific and broad professional norms and obligations for the ethical practice of science and responsible conduct of research (RCR). Scientific Professionalism Bioethics and Social Responsibility focused on current ethical and bioethical issues within the scientific profession and implications of research for society. Each small-group session examined case scenarios that included: (1) learning objectives for professional norms and obligations; (2) key ethical issues and philosophies within each topic area; (3) one or more of the RCR instructional areas; and (4) at least one type of moral reflection. Cases went beyond covering overt research misconduct to emphasize professional standards, obligations, and underlying philosophies for the ethical practice of science, competing interests of stakeholders, and oversight of science (internal and external). To our knowledge this was the first use of PBL to teach scientific integrity and ethics. Both faculty and students at Wake Forest endorsed the orientation of professionalism, active learning, and acquiring skills in contrast to a compliance-based approach that emphasizes learning rules and regulations.
