    Hoppe, Stephanie Ann

    Teaching genetics can be challenging because of the difficulty of the content and misconceptions students might hold. This thesis focused on using hands-on model activities, problem solving, and inquiry-based teaching/learning methods in order to increase student understanding in an introductory biology class in the area of genetics. Various activities using these three methods were implemented into the classes to address any misconceptions and increase student learning of the difficult concepts. The activities that were implemented were shown to be successful based on pre-post assessment score comparison. The students were assessed on the subjects of inheritance patterns, meiosis, and protein synthesis and demonstrated growth in all of the areas. It was found that hands-on models, problem solving, and inquiry-based activities were more successful in learning concepts in genetics and the students were more engaged than tradition styles of lecture.

  2. The effect of inquiry-based, hands-on labs on achievement in middle school science

    Miller, Donna Kaye Green

    The purpose of this quasi-experimental study was to measure the difference in science achievement between students who had been taught with an inquiry-based, hands-on pedagogical approach and those who had not. Improving student academic achievement and standardized test scores is the major objective of teachers, parents, school administrators, government entities, and students themselves. One major barrier to this academic success in Georgia, and the entire United States, has been the paucity of success in middle level science classes. Many studies have been conducted to determine the learning approaches that will best enable students to not only acquire a deeper understanding of science concepts, but to equip them to apply that new knowledge in their daily activities. Inquiry-based, hands-on learning involves students participating in activities that reflect methods of scientific investigation. The effective utilization of the inquiry-based learning approach demands inclusion of learners in a self-directed learning environment, the ability to think critically, and an understanding of how to reflect and reason scientifically. The treatment group using an inquiry-based, hands-on program did score slightly higher on the CRCT. However, the results revealed that there was not a significant difference in student achievement. This study showed that the traditionally instructed control group had slightly higher interest in science than the inquiry-based treatment group. The findings of this research study indicated that the NCLB mandates might need to be altered if there are no significant academic gains that result from the use of inquiry-based strategies.

    A large number of American elementary school students are now studying science using the hands-on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain abilities to do scientific inquiry and understanding about scientific inquiry. We have studied the degree to which students can do inquiries by using four hands-on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands-on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands-on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple-choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple-choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching.

    Jensen-Ruopp, Helga Spitko

    A comparison of hands-on inquiry instruction with lecture instruction was presented to 134 Patterns and Process Biology students. Students participated in seven biology lessons that were selected from Biology Survey of Living Things (1992). A pre and post paper and pencil assessment was used as the data collecting instrument. The treatment group was taught using hands-on inquiry strategies while the non-treatment group was taught in the lecture method of instruction. The team teaching model was used as the mode of presentation to the treatment group and the non-treatment group. Achievement levels using specific criterion; novice (0% to 50%), developing proficiency (51% to 69%), accomplished (70% to 84) and exceptional or mastery level (85% to 100%) were used as a guideline to tabulate the results of the pre and post assessment. Rubric tabulation was done to interpret the testing results. The raw data was plotted using percentage change in test score totals versus reading level score by gender as well as percentage change in test score totals versus auditory vocabulary score by gender. Box Whisker plot comparative descriptive of individual pre and post test scores for the treatment and non-treatment group was performed. Analysis of covariance (ANCOVA) using MINITAB Statistical Software version 14.11 was run on data of the seven lessons, as well as on gender (male results individual and combined, and female results individual and combined) results. Normal Probability Plots for total scores as well as individual test scores were performed. The results suggest that hands-on inquiry based instruction when presented to special needs students including; at-risk; English as a second language limited, English proficiency and special education inclusive students' learning may enhance individual student achievement.

  6. Action Research Using Entomological Research to Promote Hands-On Science Inquiry in a High-Poverty, Midwest Urban High School

    Stockmann, Dustin

    The purpose of this mixed-methods action research study was to examine to what extent entomological research can promote students' hands-on learning in a high-poverty, urban, secondary setting. In reviewing the literature, the researcher was not able to find a specific study that investigated how entomological research could promote the hands-on learning of students. The researcher did find evidence that research on learning in a secondary setting was important to student growth. It should also be noted that support was established for the implementation of hands-on science inquiry in the classroom setting. The study's purpose was to aid educators in their instruction by combining research-based strategies and hands-on science inquiry. The surveys asked 30 students to rate their understanding of three basic ideas. These core ideas were entomological research, hands-on science inquiry, and urban studies. These core ideas provided the foundation for the study. The questionnaires were based on follow-up ideas from the surveys. Two interview sessions were used to facilitate this one-on-one focus. Because the study included only 30 student participants, its findings may not be totally replicable. Further study investigating the links between entomological research and hands-on science learning in an urban environment is needed.

    A significant problem with inquiry teaching is that too much emphasis is placed on inquiry as a logical, scientific, and rational way of knowing. Feelings and mood are rarely dealt with except in rather off-handed remarks about intuitive leaps and creative encounters. Few consider what a model of inquiry based on mood and feeling might look like.…

    2015-08-01

    Active engagement has become the focus of many early childhood science education curricula and standards. However, active engagement usually emphasizes getting children engaged with science solely through hands-on activities. Active engagement by way of hands, heads, and hearts are kept separate and rarely discussed in terms of getting all to work together, although inquiry-based education and student interest have been accepted as important in science education. The current study is an inquiry-based research. It aims to describe and examine projects and activity stations for preschoolers in a Turkish preschool classroom bringing together the pieces of the puzzle of science education, called here 'Hands-Heads-Hearts-on Science Education'. The study, conducted from a qualitative-interpretivist paradigm, reveals that activity stations and projects create a context for hands-on (active engagement), heads-on (inquiry based or mental-engagement), and hearts-on (interest based) science education. It is found that activity stations and projects, when maintained by appropriate teacher-support, create a playful context in which children can be actively and happily engaged in science-related inquiry.

    Adapting a successful inquiry-based immersion program to create an Authentic, Hands-on, Field based Curriculum in Environmental Science at Barnard College T. C. Kenna, S. Pfirman, B. J. Mailloux, M. Stute, R. Kelsey, and P. Bower By adapting a successful inquiry-based immersion program (SEA semester) to the typical college format of classes, we are improving the technical and quantitative skills of undergraduate women and minorities in environmental science and improving their critical thinking and problem-solving by exposing our students to open-ended real-world environmental issues. Our approach uses the Hudson River Estuary as a natural laboratory. In a series of hands-on inquiry-based activities, students use advanced equipment to collect data and samples. Each class session introduces new analytical and data analysis techniques. All classes have the connecting theme of the river. Working with real data is open-ended. Our major findings as indicated by surveys as well as journaling throughout the semester are that the field- based experience significantly contributed to student learning and engagement. Journaling responses indicated that nearly all students discussed the importance and excitement of an authentic research experience. Some students were frustrated with data irregularities, uncertainty in methods and data, and the general challenge of a curriculum with inherent ambiguity. The majority were satisfied with the aims of the course to provide an integrative experience. All students demonstrated transfer of learned skills. This project has had a significant impact on our undergraduate female students: several students have pursued senior thesis projects stemming from grant activities, stating that the field activities were the highlight of their semester. Some students love the experience and want more. Others decide that they want to pursue a different career. All learn how science is conducted and have a better foundation to understand concepts such

    The study examined the effects of a technology-enhanced inquiry instructional model on students' understanding of science in Thailand. A mixed quantitative research design was selected for the research design. A pretest-posttest control-group design was implemented for the experimental research. A causal-comparative design using questionnaire and classroom observation was employed for the non-experimental research. Two sixth-grade classrooms at a medium-sized public school in Bangkok, Thailand were randomly selected for the study - one as the control group and the other as the experimental group. The 34 students in the control group only received the inquiry instructional model, while the 35 students in the experimental group received the technology-enhanced inquiry instructional model. Both groups of students had been taught by the same science teacher for 15 weeks (three periods per week). The results and findings from the study seemed to indicate that both the technology-enhanced inquiry instructional model and the inquiry instructional model significantly improve students' understanding of science. However, it might be claimed that students receiving the technology-enhanced inquiry instructional model gain more than students only receiving the inquiry instructional model. In addition, the technology-enhanced inquiry instructional model seemed to support the assessment during the 5E Model's evaluation stage. Most students appeared to have very good attitudes toward using it in the science classroom suggesting that the technology-enhanced inquiry instructional model motivates students to learn science.

  2. The effect of inquiry science activity in educational productivity

    Shimizu, Kinya

    This is a study the effect of inquiry science activity on the science achievement of junior high school students. Since the post-sputnik curriculum improvement project, science educators have supported the effect of inquiry activities. In terms of the effect of laboratory activity, however, the literature review indicated that the controlled experimental studies have failed to present the effect of laboratory activities. For example, Blosser suggested more rigid experimental design, such as longer treatment and larger sample. On the other hand, some of the recent case studies of effect of laboratory are successful to support the effect and the other recent classroom ethnographic studies indicated that the laboratory activities are implemented in inappropriate situation. This study investigates the effect of inquiry activities by using the national survey to balance the internal and external validity. In order to control the environmental effect and student aptitude, the study adopted the structural model of science achievement suggested by Reynolds and Walberg in 1991. The study utilized the extensive student and teacher data reports from the Longitudinal Study of American Youth (LSAY) to examine these differences and interactions quantitatively. The study utilized two independent variables: (1) teachers' report of the degree of their teaching emphasis on inquiry skill, and (2) teachers' report of the frequency of hands-on method. The effects of these instructional qualities are estimated in terms of the science achievement score of their student. The study utilized path analysis techniques in order to understand the complex relationship among the nine productivity factors; which are (1) motivation, (2) prior ability, (3) development, (4) home environment, (5) peer environment, (6) media environment, (7) classroom environment, (8) instructional quantity, and (9) instructional quality. The result failed to support the effectiveness of the hands-on science teaching

    This study investigated a professional development model designed to improve teachers' inquiry teaching efficacy as well as the quality of their inquiry instruction through engaging teachers in practice-teaching and reflection sessions. The programme began with a two-week summer Institute focused on both inquiry pedagogy and science content and continued with academic year support for participants' inquiry implementation. An inquiry teaching efficacy instrument was administered 3 times to 25 teacher participants to gauge changes in their personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. To examine actual practices, pre/post classroom observations of the teachers' inquiry enactments were evaluated using a quality of inquiry observation protocol. Following the summer Institute, teachers had statistically significant increases in their self-efficacy for teaching inquiry in four of the five essential features and increases in one of the five essential features for outcome expectancy. Teachers' quality of inquiry teaching also increased after the professional development programme. We discuss implications of this PD model for moving teachers towards implementation of new instructional techniques as well as the influence of a supportive school community on teachers' efficacy with inquiry instruction.

  5. A case study on modeling and independent practice cycles in teaching beginning science inquiry

    NASA Astrophysics Data System (ADS)

    Sadeghpour-Kramer, Margaret Ann Plattenberger

    With increasing pressure to produce high standardized test scores, school systems will be looking for the surest ways to increase scores. Decision makers uninformed about the value of inquiry science may recommend more direct teaching methods and curricula in the hope that students will more quickly accumulate factual information for high test scores. This researcher and other proponents of inquiry science suggest that the best preparation for any test is the ability to use all available information and problem solving skills to think through to a solution. This study proposes to test the theory that inquiry problem solving skills need to be modeled and practiced in increasingly independent situations to be learned. Students tend to copy what they have been led to believe is correct, and to avoid continued copying, their skills must be applied in new situations requiring independent practice and improvement. This study follows ten sixth grade students, selected for maximum variation, as they participate in a series of five cycles of modeling and practicing inquiry science investigations as part of an ongoing unit on water quality. The cycles were designed to make the students increasingly independent in their use of inquiry. The results showed that all ten students made significant progress from copying teacher modeling in investigation #1 towards independent inquiry, with nine of the ten achieving acceptable to good beginning independent inquiry in investigation #5. Each case was analyzed independently using such case study methodology as pattern matching, case study protocols, and theoretical propositions. Constant comparison and other case study methods were used in a cross-case analysis. Eight cases confirmed a matching set of propositions and the hypothesis, in literal replication, and the other two cases confirmed a set of propositions and the hypothesis through theoretical replication. The study suggests to educators that repeated cycles of modeling and

  10. 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

    NASA Astrophysics Data System (ADS)

    Jernnigan, Laura Jane

    Few research studies have been conducted related to inquiry-based scientific teaching methodologies and NCLB-required state testing. The purpose of this study was to examine the relationship between the strategies used by seventh-grade science teachers in Illinois and student scores on the Illinois Standards Achievement Test (ISAT) to aid in determining best practices/strategies for teaching middle school science. The literature review defines scientific inquiry by placing teaching strategies on a continuum of scientific inquiry methodologies from No Inquiry (Direct Instruction) through Authentic Inquiry. Five major divisions of scientific inquiry: structured inquiry, guided inquiry, learning cycle inquiry, open inquiry, and authentic inquiry, have been identified and described. These five divisions contain eight sub-categories: demonstrations; simple or hands-on activities; discovery learning; variations of learning cycles; problem-based, event-based, and project-based; and student inquiry, science partnerships, and Schwab's enquiry. Quantitative data were collected from pre- and posttests and surveys given to the participants: five seventh grade science teachers in four Academic Excellence Award and Spotlight Award schools and their 531 students. Findings revealed that teachers reported higher inquiry scores for themselves than for their students; the two greatest reported factors limiting teachers' use of inquiry were not enough time and concern about discipline and large class size. Although the correlation between total inquiry and mean difference of pre- and posttest scores was not statistically significant, the survey instrument indicated how often teachers used inquiry in their classes, not the type of inquiry used. Implications arose from the findings that increase the methodology debate between direction instruction and inquiry-based teaching strategies; teachers are very knowledgeable about the Illinois state standards, and various inquiry-based methods

The inquiry lab based project was designed by three stages were debriefing of basic microbiology lab skills, guided inquiry and free inquiry respectively. The Study was quasi experimental with control group pretest-posttest design. The subjects were prospective biology teachers consists of 80 students. The scientific inquiry literacy instrument refers to ScInqLiT by Wenning. The results showed that there was significant difference of scientific inquiry literacy posttest scores between experiment and control (α 0,05) and was obtained N-gain score was 0.49 (medium) to experiment and 0.24 (low) to control. Based on formative assessment showed that development of student’s scientific attitude, research and microbiology lab skills during conducting project were increased. Student’s research skills especially in identification of variables, constructing a hypothesis, communicating and concluding were increased. During implementation of inquiry project also showed that they carried out mind and hands-on and so collaborative group investigation lab activities. Our findings may aid in reforming higher-education, particularly in microbiology laboratory activities to better promote scientific inquiry literacy, scientific attitude, research and laboratory skills.

  18. Structural equation model of the relationships among inquiry-based instruction, attitudes toward science, achievement in science, and gender

    NASA Astrophysics Data System (ADS)

    Wallace, Stephen R.

    The purpose of this study was to clarify the muddled state of the magnitude and direction of the relationships among inquiry-based instruction, attitudes toward science, and science achievement, as students progressed from middle school into high school. The problem under investigation was two-fold. The first was to create and test a structural equation model describing the direction and magnitude of the relationships. The second was to determine gender differences in the relationships. Data collected from the Longitudinal Study of American Youth (LSAY) over a three-year period were used to create and test the structural equation model. Results of this study indicate inquiry-based instruction is effective in positively influencing 7th- and 8th-grade students' understandings of science concepts. Additionally, inquiry-based instruction does not have an adverse influence on science achievement in 9th grade. If the primary goal is science achievement, then an inquiry-based approach to instruction is effective. On the other hand, if the primary goal of science instruction is to positively influence students' attitudes toward science (in particular, perceptions of the usefulness of science) then inquiry-based approaches may not be the most effective method of instruction. Inquiry-based instruction adversely influences 7th-grade males' attitudes toward science and has no significant influence on 7th-grade females' attitudes toward science. In 8th grade, inquiry-based instruction has no significant influence on either genders' attitudes toward science. Not until the 9th grade does inquiry-based instruction have a significantly positive influence on males' and females' perceptions of the usefulness of science. Additionally, prior attitudes toward science significantly influences science achievement only in 8th grade and science achievement influences attitudes toward science only in 9th grade. Recommendations for further research are based on the findings and limitations of

    Jones, Mark Thomas

    2005-07-01

    Implementation of guided inquiry teaching for the first time carries inherent problems for science teachers. Reform efforts on inquiry-based science teaching are often unsustainable and are not sensitive to teachers' needs and abilities as professionals. Professional development schools are meant to provide a research-based partnership between a public school and a university. These collaborations can provide support for the professional development of teachers. This dissertation reports a study focused on the implementation of inquiry-based science kits within the support of one of these collaborations. The researcher describes the difficulties and successful adaptations experienced by science teachers and how a coteaching model provided support. These types of data are needed in order to develop a bottom-up, sustainable process that will allow teachers to implement inquiry-based science. A qualitative methodology with "researcher as participant" was used in this study of two science teachers during 2002--2003. These two teachers were supported by a coteaching model, which included preservice teachers for each teacher as well as a supervising professor. Data were collected from the researcher's direct observations of coteachers' practice. Data were also collected from interviews and reflective pieces from the coteachers. Triangulation of the data on each teacher's case supported the validity of the findings. Case reports were prepared from these data for each classroom teacher. These case reports were used and cross-case analysis was conducted to search for major themes and findings in the study. Major findings described the hurdles teachers encounter, examples of adaptations observed in the teachers' cases and the supportive interactions with their coteachers while implementing the inquiry-based kits. In addition, the data were used to make recommendations for future training and use of the kits and the coteaching model. Results from this study showed that the

  9. Designing Inquiry Starters

    NASA Astrophysics Data System (ADS)

    Kluger-Bell, B.

    2010-12-01

    The term "Inquiry Starter" comes from the Institute for Inquiry's model for teaching and learning science through inquiry. It refers to the first phase of an inquiry activity where learners engage in actions that stimulate their curiosity and generate questions for further investigation. In the Professional Development Program, staff and participants have designed a wide variety of inquiry activities with a number of variations on the inquiry starter. This has provided a laboratory for examining inquiry starter design. In this paper, I describe and examine in detail the elements of this design and how the design of those elements is related to achieving learning objectives. There are a number of important common objectives in all inquiry starters. For example, all starters must define a domain for investigation and engage the learner's curiosity in that domain. There are also critical differences in learning objectives depending on the content area being studied, the learners' background knowledge and skills, and many other factors. In this paper I examine designs for both of these types of objectives.

    2007-06-01

    Hands-On Optics (HOO) is a National Science Foundation funded program to bring optics education to traditionally underserved middle school students. We have developed six modules that teach students optics concepts through hands-on, inquiry-based activities. The modules have been used extensively in after-school and non-school settings such as in the Boys and Girls Clubs in South Tucson, Arizona and the Boys and Girls Club in Sells, Arizona on the Tohono O'odham reservation. We will describe these programs and the lessons learned in these settings. These modules also form the basis for a week-long optics camp that provides students with approximately 40 hours of instruction time in optics. We will provide an outline of the activities and concepts covered in the camp. These camps provide an ideal way to encourage interest in optics before career choices are developed.

  17. Community of inquiry model: advancing distance learning in nurse anesthesia education.

    PubMed

    Pecka, Shannon L; Kotcherlakota, Suhasini; Berger, Ann M

    2014-06-01

    The number of distance education courses offered by nurse anesthesia programs has increased substantially. Emerging distance learning trends must be researched to ensure high-quality education for student registered nurse anesthetists. However, research to examine distance learning has been hampered by a lack of theoretical models. This article introduces the Community of Inquiry model for use in nurse anesthesia education. This model has been used for more than a decade to guide and research distance learning in higher education. A major strength of this model learning. However, it lacks applicability to the development of higher order thinking for student registered nurse anesthetists. Thus, a new derived Community of Inquiry model was designed to improve these students' higher order thinking in distance learning. The derived model integrates Bloom's revised taxonomy into the original Community of Inquiry model and provides a means to design, evaluate, and research higher order thinking in nurse anesthesia distance education courses.

    During the summer of 2011, the Mālama Ke Ahupua`a (to care of our watershed) GEARUP summer program provided 25 under-served and under-represented minority public high school students (Hawaiian, part-Hawaiian, Filipino, Pacific Islanders) from Farrington High School (Kalihi, Honolulu) with a hands-on place-based multidiscipline course located within Manoa Valley (Ahupua`a O Kona) with the objective of engaging participants in scientific environmental investigations while exploring Hawaii's linkages between traditional knowledge, culture and science. The 4-week field program enabled students to collect samples along the perennial Manoa Stream and conduct water quality assessments throughout the Manoa watershed. Students collected science quality data from eight different sampling stations by means of field- and laboratory-based quantitative water quality testing equipment and GPS/GIS technology. While earning Hawaii DOE academic credits, students were able to document changes along the stream as related to pollution and urbanization. While conducting the various scientific investigations, students also participated in cultural fieldtrips and activities that highlighted the linkages between historical sustainable watershed uses by native Hawaiian communities, and their connections with natural earth processes. Additionally, students also participated in environmental service-learning projects that highlight the Hawaiian values of laulima (teamwork), mālama (to care for), and imi `ike (to seek knowledge). By contextualizing and merging hands-on place-based earth science inquiry with native Hawaiian traditional knowledge, students experienced the natural-cultural significance of their ahupua`a (watershed). This highlighted the advantages for promoting environmental literacy and geoscience education to under-served and under-represented minority populations in Hawaii from a rich native Hawaiian cultural framework.

    Walan, Susanne; Mc Ewen, Birgitta

    2017-04-01

    Inquiry- and context-based teaching strategies have been proven to stimulate and motivate students' interests in learning science. In this study, 12 teachers reflected on these strategies after using them in primary schools. The teachers participated in a continuous professional development (CPD) programme. During the programme, they were also introduced to a teaching model from a European project, where inquiry- and context-based education (IC-BaSE) strategies were fused. The research question related to teachers' reflections on these teaching strategies, and whether they found the model to be useful in primary schools after testing it with their students. Data collection was performed during the CPD programme and consisted of audio-recorded group discussions, individual portfolios and field notes collected by researchers. Results showed that compared with using only one instructional strategy, teachers found the new teaching model to be a useful complement. However, their discussions also showed that they did not reflect on choices of strategies or purposes and aims relating to students' understanding, or the content to be taught. Before the CPD programme, teachers discussed the use of inquiry mainly from the aspect that students enjoy practical work. After the programme, they identified additional reasons for using inquiry and discussed the importance of knowing why inquiry is performed. However, to develop teachers' knowledge of instructional strategies as well as purposes for using certain strategies, there is need for further investigations among primary school teachers.

    Hanegan, Nikki L.; Bigler, Amber

    2009-10-01

    Societal benefit depends on the general public's understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439-443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57-69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93-99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110-134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175-218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916-937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as "authentic" if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110-134, 2009; Chinn and Malhotra in Sci Educ 86(2):175-218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced

    NASA Astrophysics Data System (ADS)

    Gregorcic, Bor; Planinsic, Gorazd; Etkina, Eugenia

    2017-12-01

    In this paper, we investigate some of the ways in which students, when given the opportunity and an appropriate learning environment, spontaneously engage in collaborative inquiry. We studied small groups of high school students interacting around and with an interactive whiteboard equipped with Algodoo software, as they investigated orbital motion. Using multimodal discourse analysis, we found that in their discussions the students relied heavily on nonverbal meaning-making resources, most notably hand gestures and resources in the surrounding environment (items displayed on the interactive whiteboard). They juxtaposed talk with gestures and resources in the environment to communicate ideas that they initially were not able to express using words alone. By spontaneously recruiting and combining a diverse set of meaning-making resources, the students were able to express relatively fluently complex ideas on a novel physics topic, and to engage in practices that resemble a scientific approach to exploration of new phenomena.

  10. The relationship between inquiry-based science instruction and student achievement

    NASA Astrophysics Data System (ADS)

    Suarez, Michael Louis

    Teaching science through inquiry has become a focus of recent educational reform in Mississippi and other states. Based on the Constructivist learning theory, inquiry instruction can take many forms, but generally follows the scientific method by requiring students to learn concepts through experimentation and real-world, hands-on experiences. This dissertation examines the relationship between the amounts of time spent using inquiry-based science instruction and student achievement as measured by the Mississippi State Science Assessment. The study also identifies teacher perceptions of inquiry and the amount of professional development received by participants on using inquiry-based instructional techniques. Finally, this study identifies factors that hinder the use of inquiry. Using a 24-question written survey, the researcher collected quantitative data from 204 science teachers in grades K-8 in four southern Mississippi school districts. Participants rated their average amount of time spent using inquiry-based science instruction in their classrooms. These results were then compared to each school's average test score on the 2009-2010 Mississippi State Science Assessment using a Spearman rho correlation. A significant positive relationship was found between amounts of time spent using inquiry-based science instruction and student achievement. The participants also indicated their perceptions of inquiry, amount of professional development, and deterrents to inquiry usage on a five-point Likert scale survey. Overall, participants held a favorable opinion of inquiry-based instruction and felt that it was important for their students' success. Over half of participants had not attended professional development on inquiry-based instruction. A majority indicated a desire for professional development. The most commonly identified factor hindering the use of inquiry was a lack of materials and resources. Many participants also indicated that time constraints prevented

    2017-01-01

    This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers' attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers' attitudes. Teachers felt less anxious about teaching science and felt less dependent on contextual factors compared to the control group. With regard to attitude towards conducting inquiry, teachers felt less anxious and more able to conduct an inquiry project. There were no effects on other attitude components, such as self-efficacy beliefs or relevance beliefs, or on self-reported science teaching behaviour. These results indicate that practitioner research may have a partially positive effect on teachers' attitudes, but that it may not be sufficient to fully change primary teachers' attitudes and their actual science teaching behaviour. In comparison, a previous study showed that attitude-focused professional development in science education has a more profound impact on primary teachers' attitudes and science teaching behaviour. In our view, future interventions aiming to stimulate science teaching should combine both approaches, an explicit focus on attitude change together with familiarisation with inquiry, in order to improve primary teachers' attitudes and classroom practices.

    Nichols, Kim; Burgh, Gilbert; Kennedy, Callie

    2017-02-01

    Developing students' skills to pose and respond to questions and actively engage in inquiry behaviours enables students to problem solve and critically engage with learning and society. The aim of this study was to analyse the impact of providing teachers with an intervention in inquiry pedagogy alongside inquiry science curriculum in comparison to an intervention in non-inquiry pedagogy alongside inquiry science curriculum on student questioning and other inquiry behaviours. Teacher participants in the comparison condition received training in four inquiry-based science units and in collaborative strategic reading. The experimental group, the community of inquiry (COI) condition, received training in facilitating a COI in addition to training in the same four inquiry-based science units. This study involved 227 students and 18 teachers in 9 primary schools across Brisbane, Australia. The teachers were randomly allocated by school to one of the two conditions. The study followed the students across years 6 and 7 and students' discourse during small group activities was recorded, transcribed and coded for verbal inquiry behaviours. In the second year of the study, students in the COI condition demonstrated a significantly higher frequency of procedural and substantive higher-order thinking questions and other inquiry behaviours than those in the comparison condition. Implementing a COI within an inquiry science curriculum develops students' questioning and science inquiry behaviours and allows teachers to foster inquiry skills predicated by the Australian Science Curriculum. Provision of inquiry science curriculum resources alone is not sufficient to promote the questioning and other verbal inquiry behaviours predicated by the Australian Science Curriculum.

Students are better able to incorporate and make sense of new ideas when they are aware of their own prior knowledge (Resnick et al. 1989; Confrey 1990), have the opportunity to develop explanations from their own experience in their own words (McDermott 1991; Prather et al. 2004), and benefit from peer instruction (Mazur 1997; Green 2003). Students in astronomy courses often have difficulty understanding many different concepts as a result of difficulties with spatial reasoning and a sense of scale. The Hands-on-Science program at UT Austin incorporates these research-based results into four guided-inquiry, integrated science courses (50 students each). They are aimed at pre-service K-5 teachers but are open to other majors as well. We find that Hands-on-Science students not only attain more favorable changes in attitude towards science, but they also outperform students in traditional lecture courses in content gains. Workshop Outcomes: Participants experienced a research-based, guided-inquiry lesson about the motion of objects in the sky and discussed the research methodology for assessing students in such a course.

    A pre-service science and mathematics teacher participated in an action research project to reform a chemistry course required of elementary and middle childhood pre-service teachers. Activities to emphasize a hands-on approach to learning chemistry and to model teaching science through inquiry for these pre-service teachers are described. The value of a research experience for pre-service teachers, both upon their student teaching and as a classroom teacher, is discussed.

  1. Designing a Web-Based Science Learning Environment for Model-Based Collaborative Inquiry

    NASA Astrophysics Data System (ADS)

    Sun, Daner; Looi, Chee-Kit

    2013-02-01

    The paper traces a research process in the design and development of a science learning environment called WiMVT (web-based inquirer with modeling and visualization technology). The WiMVT system is designed to help secondary school students build a sophisticated understanding of scientific conceptions, and the science inquiry process, as well as develop critical learning skills through model-based collaborative inquiry approach. It is intended to support collaborative inquiry, real-time social interaction, progressive modeling, and to provide multiple sources of scaffolding for students. We first discuss the theoretical underpinnings for synthesizing the WiMVT design framework, introduce the components and features of the system, and describe the proposed work flow of WiMVT instruction. We also elucidate our research approach that supports the development of the system. Finally, the findings of a pilot study are briefly presented to demonstrate of the potential for learning efficacy of the WiMVT implementation in science learning. Implications are drawn on how to improve the existing system, refine teaching strategies and provide feedback to researchers, designers and teachers. This pilot study informs designers like us on how to narrow the gap between the learning environment's intended design and its actual usage in the classroom.

  2. Which Type of Inquiry Project Do High School Biology Students Prefer: Open or Guided?

    In teaching inquiry to high school students, educators differ on which method of teaching inquiry is more effective: Guided or open inquiry? This paper examines the influence of these two different inquiry learning approaches on the attitudes of Israeli high school biology students toward their inquiry project. The results showed significant differences between the two groups: Open inquiry students were more satisfied and felt they gained benefits from implementing the project to a greater extent than guided inquiry students. On the other hand, regarding documentation throughout the project, guided inquiry students believed that they conducted more documentation, as compared to their open inquiry peers. No significant differences were found regarding `the investment of time', but significant differences were found in the time invested and difficulties which arose concerning the different stages of the inquiry process: Open inquiry students believed they spent more time in the first stages of the project, while guided inquiry students believed they spent more time in writing the final paper. In addition, other differences were found: Open inquiry students felt more involved in their project, and felt a greater sense of cooperation with others, in comparison to guided inquiry students. These findings may help teachers who hesitate to teach open inquiry to implement this method of inquiry; or at least provide their students with the opportunity to be more involved in inquiry projects, and ultimately provide their students with more autonomy, high-order thinking, and a deeper understanding in performing science.

  4. A Design Model of Distributed Scaffolding for Inquiry-Based Learning

    NASA Astrophysics Data System (ADS)

    Hsu, Ying-Shao; Lai, Ting-Ling; Hsu, Wei-Hsiu

    2015-04-01

    This study presents a series of three experiments that focus on how distributed scaffolding influences learners' conceptual understanding and reasoning from combined levels of triangulation, at the interactive level (discourses within a focus group) and the collective level (class). Three inquiry lessons on plate tectonics (LPT) were designed, implemented and redesigned to explore how students responded to the scaffoldings provided. The results show that the goal-oriented version (LPT3) was significantly more effective at helping students develop an understanding of plate tectonics and evidence-based reasoning than the teacher-led (LPT1) and deconstructed (LPT2) versions ( χ 2 = 11.56, p < 0.003). In LPT3, we can identify three key features of the scaffolding: an advanced organizer, deconstruction of complex tasks, and reflection on the whole inquiry cycle at the end of class time. In addition, LPT3 took much less teaching time. In other words, it appears to be effective and efficient, most likely due to synergies between teacher facilitation and lesson scaffolds. The empirical results clarify the functions of the design model proposed for distributed scaffolding: navigating inquiry, structuring tasks, supporting communication, and fostering reflection. Future studies should more closely evaluate the scaffolding system as a whole and synergies between different types of scaffolds for advancing learning.

  9. 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

    2011-02-01

    This study investigates the beliefs and practices of seven high school chemistry teachers as a result of their participation in a year-long inquiry professional development (PD) project. An analysis of oral interviews, written reflections, and in-class observations were used to determine the extent to which the PD affected the teachers' beliefs and practice. The data indicated that the teachers developed more complete conceptions of classroom inquiry, valued a "phenomena first" approach to scientific investigations, and viewed inquiry approaches as helpful for facilitating improved student thinking. Analysis of classroom observations with the Reformed Teaching Observation Protocol indicated that features of the PD were observed in the teachers' practice during the academic year follow-up. Implications for effective science teacher professional development models are discussed.

    Brand, Brenda R.; Moore, Sandra J.

    2011-05-01

    This two-year school-wide initiative to improve teachers' pedagogical skills in inquiry-based science instruction using a constructivist sociocultural professional development model involved 30 elementary teachers from one school, three university faculty, and two central office content supervisors. Research was conducted for investigating the impact of the professional development activities on teachers' practices, documenting changes in their philosophies, instruction, and the learning environment. This report includes teachers' accounts of philosophical as well as instructional changes and how these changes shaped the learning environment. For the teachers in this study, examining their teaching practices in learner-centered collaborative group settings encouraged them to critically analyze their instructional practices, challenging their preconceived ideas on inquiry-based strategies. Additionally, other factors affecting teachers' understanding and use of inquiry-based strategies were highlighted, such as self-efficacy beliefs, prior experiences as students in science classrooms, teacher preparation programs, and expectations due to federal, state, and local mandates. These factors were discussed and reconciled, as they constructed new understandings and adapted their strategies to become more student-centered and inquiry-based.

  17. Teaching science as inquiry in US and in Japan: A cross-cultural comparison of science teachers' understanding of, and attitudes toward inquiry-based teaching

    NASA Astrophysics Data System (ADS)

    Tosa, Sachiko

    Since the publication of the National Science Education Standards in 1996, learning science through inquiry has been regarded as the heart of science education. However, the TIMSS 1999 Video Study showed that inquiry-based teaching has been taking place less in the United States than in Japan. This study examined similarities and differences in how Japanese and American middle-school science teachers think and feel about inquiry-based teaching. Teachers' attitudes toward the use of inquiry in science teaching were measured through a survey instrument (N=191). Teachers' understanding of inquiry-based teaching was examined through interviews and classroom observations in the United States (N=9) and Japan (N=15). The results show that in spite of the variations in teachers' definitions of inquiry-based teaching, teachers in both countries strongly agree with the idea of inquiry-based teaching. However, little inquiry-based teaching was observed in either of the countries for different reasons. The data indicate that Japanese teachers did not generally help students construct their own understanding of scientific concepts in spite of well-planned lesson structures and activity set-ups. On the other hand, the observational data indicate that American teachers often lacked meaningful science content in spite of their high level of pedagogical knowledge. The need for addressing the importance of scientific concepts in teacher preparation programs in higher education institutions in the US is advocated. To the Japanese science education community, the need for teachers' acquisition of instructional strategies for inquiry-based teaching is strongly addressed.

  20. Development of interest in science and interest in teaching elementary science: Influence of informal, school, and inquiry methods course experiences

    NASA Astrophysics Data System (ADS)

    Bulunuz, Mizrap

    Inquiry-based science instruction is a major goal of science education reform. However, there is little research examining how preservice elementary teachers might be motivated to teach through inquiry. This quantitative study was designed to examine the role of background experiences and an inquiry science methods course on interest in science and interest in teaching science. The course included many activities and assignments at varying levels of inquiry, designed to teach content and inquiry methods and to model effective teaching. The study involved analyses of surveys completed by students in the course on their experiences with science before, during, and at the end of the course. The following questions guided the design of this study and analysis of the data: (1) What science background experiences (school, home, and informal education) do participants have and how do those experiences affect initial interest in science? (2) Among the hands-on activities in the methods course, is there a relationship between level of inquiry of the activity and the motivational quality (interesting, fun, and learning) of the activity? (3) Does the course affect participants' interest and attitude toward science? (4) What aspects of the course contribute to participants' interest in teaching science and choice to teach science? Descriptive and inferential analysis of a background survey revealed that participants with high and low initial interest in science differed significantly on remembering about elementary school science and involvement in science related activities in childhood/youth. Analysis of daily ratings of each hands-on activity on motivational qualities (fun, interest, and learning) indicated that there were significant differences in motivational quality of the activities by level of inquiry with higher levels of inquiry rated more positively. Pre/post surveys indicated that participants increased in interest in science and a number of variables reflecting

  3. Teachers' Perspectives on Online Virtual Labs vs. Hands-On Labs in High School Science

    NASA Astrophysics Data System (ADS)

    Bohr, Teresa M.

    This study of online science teachers' opinions addressed the use of virtual labs in online courses. A growing number of schools use virtual labs that must meet mandated laboratory standards to ensure they provide learning experiences comparable to hands-on labs, which are an integral part of science curricula. The purpose of this qualitative case study was to examine teachers' perceptions of the quality and effectiveness of high school virtual labs. The theoretical foundation was constructivism, as labs provide student-centered activities for problem solving, inquiry, and exploration of phenomena. The research questions focused on experienced teachers' perceptions of the quality of virtual vs. hands-on labs. Data were collected through survey questions derived from the lab objectives of The Next Generation Science Standards . Eighteen teachers rated the degree of importance of each objective and also rated how they felt virtual labs met these objectives; these ratings were reported using descriptive statistics. Responses to open-ended questions were few and served to illustrate the numerical results. Many teachers stated that virtual labs are valuable supplements but could not completely replace hands-on experiences. Studies on the quality and effectiveness of high school virtual labs are limited despite widespread use. Comprehensive studies will ensure that online students have equal access to quality labs. School districts need to define lab requirements, and colleges need to specify the lab experience they require. This study has potential to inspire positive social change by assisting science educators, including those in the local school district, in evaluating and selecting courseware designed to promote higher order thinking skills, real-world problem solving, and development of strong inquiry skills, thereby improving science instruction for all high school students.

    2018-01-01

    The purpose of this research was to investigate the effect of integrating cooperative learning into 5E inquiry learning model on interpersonal skills of high school students. Two 10th grade classrooms consisting of 63 students were obtained by purposive sampling then one was assigned as an experimental and the other as a control group. The cooperative learning was integrated into 5E inquiry model for the experimental group in addition to the normal 5E inquiry model in the control group. A 5-level rating scale questionnaire was used for data collection both before and after the experiment. Furthermore, a descriptive journal from each student was added to the study after the researchers realized a significant difference in the teamwork skill of each group. Data from questionnaires were analyzed using descriptive statistics and inferential statistics. The results showed that the experimental group had a significantly higher score of interpersonal skills when compared to the control group (p<0.05). The results showed a clearly difference in teamwork of the two groups. The journals of the students showed the difference of working preference among two group. It could conclude that the learning intervention enhanced team working in 5 aspects including time management, the outcome of the work, the process of the work and the attitude of the students. The students in the experimental group demonstrated more creative ideas and were more likely to listen to other student ideas. The students in experimental group were less competitive and were more open in sharing and helping others. In conclusion, the addition of cooperative learning in to the usual 5E inquiry learning, not only help the students to achieve the knowledge but also help develop good interpersonal skills.

  9. Withholding answers during hands-on scientific investigations? Comparing effects on developing students' scientific knowledge, reasoning, and application

    NASA Astrophysics Data System (ADS)

    Zhang, Lin

    2018-03-01

    As more concerns have been raised about withholding answers during science teaching, this article argues for a need to detach 'withholding answers' from 'hands-on' investigation tasks. The present study examined students' learning of light-related content through three conditions: 'hands-on' + no 'withholding' (hands-on only: HO), 'hands-on' + 'withholding' (hands-on investigation with answers withheld: HOW), and no 'hands-on' + no 'withholding' (direction instruction: DI). Students were assessed in terms of how well they (1) knew the content taught in class; (2) reasoned with the learned content; and (3) applied the learned content to real-life situations. Nine classes of students at 4th and 5th grades, N = 136 in total, were randomly assigned to one of the three conditions. ANCOVA results showed that students in the hands-on only condition reasoned significantly better than those in the other two conditions. Students in this condition also seemed to know the content fairly better although the advance was not significant. Students in all three conditions did not show a statistically significant difference in their ability to apply the learned content to real-life situations. The findings from this study provide important contributions regarding issues relating to withholding answers during guided scientific inquiry.

  10. Inquiry Learning in the Singaporean Context: Factors affecting student interest in school science

    Jocz, Jennifer Ann; Zhai, Junqing; Tan, Aik Ling

    2014-10-01

    Recent research reveals that students' interest in school science begins to decline at an early age. As this lack of interest could result in fewer individuals qualified for scientific careers and a population unprepared to engage with scientific societal issues, it is imperative to investigate ways in which interest in school science can be increased. Studies have suggested that inquiry learning is one way to increase interest in science. Inquiry learning forms the core of the primary syllabus in Singapore; as such, we examine how inquiry practices may shape students' perceptions of science and school science. This study investigates how classroom inquiry activities relate to students' interest in school science. Data were collected from 425 grade 4 students who responded to a questionnaire and 27 students who participated in follow-up focus group interviews conducted in 14 classrooms in Singapore. Results indicate that students have a high interest in science class. Additionally, self-efficacy and leisure-time science activities, but not gender, were significantly associated with an increased interest in school science. Interestingly, while hands-on activities are viewed as fun and interesting, connecting learning to real-life and discussing ideas with their peers had a greater relation to student interest in school science. These findings suggest that inquiry learning can increase Singaporean students' interest in school science; however, simply engaging students in hands-on activities is insufficient. Instead, student interest may be increased by ensuring that classroom activities emphasize the everyday applications of science and allow for peer discussion.

  17. A Structured-Inquiry Approach to Teaching Neurophysiology Using Computer Simulation

    PubMed Central

    Crisp, Kevin M.

    2012-01-01

    Computer simulation is a valuable tool for teaching the fundamentals of neurophysiology in undergraduate laboratories where time and equipment limitations restrict the amount of course content that can be delivered through hands-on interaction. However, students often find such exercises to be tedious and unstimulating. In an effort to engage students in the use of computational modeling while developing a deeper understanding of neurophysiology, an attempt was made to use an educational neurosimulation environment as the basis for a novel, inquiry-based research project. During the semester, students in the class wrote a research proposal, used the Neurodynamix II simulator to generate a large data set, analyzed their modeling results statistically, and presented their findings at the Midbrains Neuroscience Consortium undergraduate poster session. Learning was assessed in the form of a series of short term papers and two 10-min in-class writing responses to the open-ended question, “How do ion channels influence neuronal firing?”, which they completed on weeks 6 and 15 of the semester. Students’ answers to this question showed a deeper understanding of neuronal excitability after the project; their term papers revealed evidence of critical thinking about computational modeling and neuronal excitability. Suggestions for the adaptation of this structured-inquiry approach into shorter term lab experiences are discussed. PMID:23494064

  19. Learning ion solid interactions hands-on: An activity based, inquiry oriented, graduate course

    NASA Astrophysics Data System (ADS)

    Braunstein, Gabriel

    2005-12-01

    Experimental work, using state of the art instrumentation, is integrated with lectures in a "real life", learning by discovery approach, in the Ion-Solid Interactions graduate/undergraduate course offered by the Department of Physics of the University of Central Florida. The lecture component of the course covers the underlying physical principles, and related scientific and technological applications, associated with the interaction of energetic ions with matter. In the experimental section the students form small groups and perform a variety of projects, experimental and computational, as part of a participative, inquiry oriented, learning process. In the most recent offering of the class, the students deposited a compound semiconductor thin film by dual-gun sputtering deposition, where each group aimed at a different stoichiometry of the same compound (Zn1-xSxOy). Then they analyzed the composition using Rutherford backscattering spectrometry, measured electrical transport properties using Hall effect and conductivity measurements, and determined the band gap using spectrophotometry. Finally the groups shared their results and each wrote a 'journal-like' technical article describing the entire work. In a different assignment, each group also developed a Monte Carlo computer program ('TRIM-like') to simulate the penetration of ions into a solid, in ion implantation, calculating the stopping cross-sections with approximate models, taught in class, which can be analytically solved. The combination of classroom/laboratory activities is very well received by the students. They gain real life experience operating state of the art equipment, and working in teams, while performing research-like projects, and simultaneously they learn the theoretical foundations of the discipline.

    Pena, Edward; Thompson, David E.

    1997-01-01

    Knowing the tendon forces generated for a given task such as grasping via a model, an artificial hand can be controlled. A two-dimensional force model for the index finger was developed. This system is assumed to be in static equilibrium, therefore, the equations of equilibrium were applied at each joint. Constraint equations describing the tendon branch connectivity were used. Gaussian elimination was used to solve for the unknowns of the Linear system. Results from initial work on estimating tendon forces in post-operative hands during active motion therapy were discussed. The results are important for understanding the effects of hand position on tendon tension, elastic effects on tendon tension, and overall functional anatomy of the hand.

  3. Refining Inquiry with Multi-Form Assessment: Formative and summative assessment functions for flexible inquiry

    NASA Astrophysics Data System (ADS)

    Zuiker, Steven; Reid Whitaker, J.

    2014-04-01

    This paper describes the 5E+I/A inquiry model and reports a case study of one curricular enactment by a US fifth-grade classroom. A literature review establishes the model's conceptual adequacy with respect to longstanding research related to both the 5E inquiry model and multiple, incremental innovations of it. As a collective line of research, the review highlights a common emphasis on formative assessment, at times coupled either with differentiated instruction strategies or with activities that target the generalization of learning. The 5E+I/A model contributes a multi-level assessment strategy that balances formative and summative functions of multiple forms of assessment in order to support classroom participation while still attending to individual achievement. The case report documents the enactment of a weeklong 5E+I/A curricular design as a preliminary account of the model's empirical adequacy. A descriptive and analytical narrative illustrates variable ways that multi-level assessment makes student thinking visible and pedagogical decision-making more powerful. In light of both, it also documents productive adaptations to a flexible curricular design and considers future research to advance this collective line of inquiry.

  5. The influence of the Inquiry Institute on elementary teachers' perceptions of inquiry learning in the science classroom

    NASA Astrophysics Data System (ADS)

    Williams-Rossi, Dara

    Despite the positive outcomes for inquiry-based science education and recommendations from national and state standards, many teachers continue to rely upon more traditional methods of instruction This causal-comparative study was designed to determine the effects of the Inquiry Institute, a professional development program that is intended to strengthen science teachers' pedagogical knowledge and provide practice with inquiry methods based from a constructivist approach. This study will provide a understanding of a cause and effect relationship within three levels of the independent variable---length of participation in the Inquiry Institute (zero, three, or six days)---to determine whether or not the three groups differ on the dependent variables---beliefs, implementation, and barriers. Quantitative data were collected with the Science Inquiry Survey, a researcher-developed instrument designed to also ascertain qualitative information with the use of open-ended survey items. One-way ANOVAs were applied to the data to test for a significant difference in the means of the three groups. The findings of this study indicate that lengthier professional development in the Inquiry Institute holds the most benefits for the participants.

    Hadi, S. A.; Susantini, E.; Agustini, R.

    2018-01-01

    This research aimed at training students’ critical thinking skills through the implementation of a modified free inquiry learning model. The subjects of this research were 21 students of Mathematics Semester II. Using One-Group Pretest-Posttest Design, the data were analyzed descriptively using N-gain indicator. The results indicate that the modified free inquiry learning model was effective to train students’ critical thinking skills. The increase in the students’ critical thinking skills viewed from the value of N-Gain has a range of values with the categories of medium and high with a score between 0,25-0,95. Overall, the change in N-Gain score of each student and each indicator of critical thinking skills is as increasing with a moderate category. The increase of N-Gain value is resulted from the fact that the students were directly involved in organizing their learning process. These criteria indicate that the modified free inquiry learning model can be used to train students’ critical thinking skills on photosynthesis and cellular respiration materials. The results of this research are expected to be nationally implemented to familiarize students with andragogy learning style which places the students as the subjects of learning.

  7. Inquiry based learning with a virtual microscope

    NASA Astrophysics Data System (ADS)

    Kelley, S. P.; Sharples, M.; Tindle, A.; Villasclaras-Fernández, E.

    2012-12-01

    As part of newly funded initiative, the Wolfson OpenScience Laboratory, we are linking a tool for inquiry based learning, nQuire (http://www.nquire.org.uk) with the virtual microscope for Earth science (http://www.virtualmicroscope.co.uk) to allow students to undertake projects and gain from inquiry based study thin sections of rocks without the need for a laboratory with expensive petrological microscopes. The Virtual Microscope (VM) was developed for undergraduate teaching of petrology and geoscience, allowing students to explore rock hand specimens and thin sections in a browser window. The system is based on HTML5 application and allows students to scan and zoom the rocks in a browser window, view in ppl and xpl conditions, and rotate specific areas to view birefringence and pleochroism. Importantly the VM allows students to gain access to rare specimens such as Moon rocks that might be too precious to suffer loss or damage. Experimentation with such specimens can inspire the learners' interest in science and allows them to investigate relevant science questions. Yet it is challenging for learners to engage in scientific processes, as they may lack scientific investigation skills or have problems in planning their activities; for teachers, managing inquiry activities is a demanding task (Quintana et al., 2004). To facilitate the realization of inquiry activities, the VM is being integrated with the nQuire tool. nQuire is a web tool that guides and supports students through the inquiry process (Mulholland et al., 2011). Learners are encouraged to construct their own personally relevant hypothesis, pose scientific questions, and plan the method to answer them. Then, the system enables users to collect and analyze data, and share their conclusions. Teachers can monitor their students' progress through inquiries, and give them access to new parts of inquiries as they advance. By means of the integration of nQuire and the VM, inquiries that involve collecting data

  9. The effect of inquiry-based learning experiences on adolescents' science-related career aspiration in the Finnish context

    NASA Astrophysics Data System (ADS)

    Kang, Jingoo; Keinonen, Tuula

    2017-08-01

    Much research has been conducted to investigate the effects of inquiry-based learning on students' attitude towards science and future involvement in the science field, but few of them conducted in-depth studies including young learners' socio-cognitive background to explore mechanisms which explain how inquiry experiences influence on career choices. Hence, the aim of this study was to investigate in what ways and to what extent the inquiry learning experiences in school science affect students' future career orientation in the context of socio-cognitive mechanisms based on socio-cognitive career theory(SCCT). For the purpose, Programme for International Student Assessment (PISA) 2015 data were used focusing on science literacy, and the sample of Finnish 15-year-old students (N = 5782) was analysed by structural equation modelling with the hypothesised Inquiry-SCCT model. The results of the study showed that inquiry learning experiences were indicated as a positive predictor for the students' career aspiration, and most of its effects were mediated by outcome expectations. Indeed, although self-efficacy and interest in learning science indicated positive correlations with future aspiration, outcome expectation presented the highest correlation with the science-related career. Gender differences were found in the model, but girls indicated higher outcome expectation and career aspiration than boys in Finland.

  15. Analyzing Students' Learning Progressions Throughout a Teaching Sequence on Acoustic Properties of Materials with a Model-Based Inquiry Approach

    NASA Astrophysics Data System (ADS)

    Hernández, María Isabel; Couso, Digna; Pintó, Roser

    2015-04-01

    The study we have carried out aims to characterize 15- to 16-year-old students' learning progressions throughout the implementation of a teaching-learning sequence on the acoustic properties of materials. Our purpose is to better understand students' modeling processes about this topic and to identify how the instructional design and actual enactment influences students' learning progressions. This article presents the design principles which elicit the structure and types of modeling and inquiry activities designed to promote students' development of three conceptual models. Some of these activities are enhanced by the use of ICT such as sound level meters connected to data capture systems, which facilitate the measurement of the intensity level of sound emitted by a sound source and transmitted through different materials. Framing this study within the design-based research paradigm, it consists of the experimentation of the designed teaching sequence with two groups of students ( n = 29) in their science classes. The analysis of students' written productions together with classroom observations of the implementation of the teaching sequence allowed characterizing students' development of the conceptual models. Moreover, we could evidence the influence of different modeling and inquiry activities on students' development of the conceptual models, identifying those that have a major impact on students' modeling processes. Having evidenced different levels of development of each conceptual model, our results have been interpreted in terms of the attributes of each conceptual model, the distance between students' preliminary mental models and the intended conceptual models, and the instructional design and enactment.

  18. At the Elbows of Scientists: Shaping Science Teachers' Conceptions and Enactment of Inquiry-Based Instruction

    NASA Astrophysics Data System (ADS)

    McLaughlin, Cheryl A.; MacFadden, Bruce J.

    2014-12-01

    This study stemmed from concerns among researchers that reform efforts grounded in promoting inquiry as the basis for teaching science have not achieved the desired changes in American science classrooms. Many science teachers assume that they are employing inquiry-based strategies when they use cookbook investigations with highly structured step-by-step instructions. Additionally, most science teachers equate hands-on activities with classroom inquiry and, as such, repeatedly use prepackaged, disconnected activities to break the monotony of direct instruction. Despite participation in numerous professional development activities, many science teachers continue to hold misconceptions about inquiry that influence the way they design and enact instruction. To date, there is very limited research exploring the role of inquiry-based professional development in facilitating desired changes in science teachers' conceptions of inquiry. This qualitative study of five high school science teachers explores the ways in which authentic inquiry experiences with a team of scientists in Panama shaped their conceptions and reported enactments of inquiry-based instruction. Our findings suggest that professional development experiences engaging science teachers in authentic research with scientists have the potential to change teachers' naïve conceptions of inquiry, provided that necessary supports are provided for reflection and lesson design.

  20. Sandboxes for Model-Based Inquiry

    NASA Astrophysics Data System (ADS)

    Brady, Corey; Holbert, Nathan; Soylu, Firat; Novak, Michael; Wilensky, Uri

    2015-04-01

    In this article, we introduce a class of constructionist learning environments that we call Emergent Systems Sandboxes ( ESSs), which have served as a centerpiece of our recent work in developing curriculum to support scalable model-based learning in classroom settings. ESSs are a carefully specified form of virtual construction environment that support students in creating, exploring, and sharing computational models of dynamic systems that exhibit emergent phenomena. They provide learners with "entity"-level construction primitives that reflect an underlying scientific model. These primitives can be directly "painted" into a sandbox space, where they can then be combined, arranged, and manipulated to construct complex systems and explore the emergent properties of those systems. We argue that ESSs offer a means of addressing some of the key barriers to adopting rich, constructionist model-based inquiry approaches in science classrooms at scale. Situating the ESS in a large-scale science modeling curriculum we are implementing across the USA, we describe how the unique "entity-level" primitive design of an ESS facilitates knowledge system refinement at both an individual and social level, we describe how it supports flexible modeling practices by providing both continuous and discrete modes of executability, and we illustrate how it offers students a variety of opportunities for validating their qualitative understandings of emergent systems as they develop.

  1. Investigating Teachers' Beliefs in the Implementation of Science Inquiry and Science Fair in Three Boston High Schools

    NASA Astrophysics Data System (ADS)

    De Barros Miller, Anne Marie

    In previous decades, inquiry has been the focus of science education reform in the United States. This study sought to investigate how teachers' beliefs affect their implementation of inquiry science and science fair. It was hypothesized that science teachers' beliefs about inquiry science and science fair are predictive of their implementation of such strategies. A case study approach and semi-structured interviews were employed to collect the data, and an original thematic approach was created to analyze the data. Findings seem to suggest that science teachers who embrace science inquiry and science fair believe these practices enhance students' performance, facilitate their learning experience, and allow them to take ownership of their learning. However, results also suggest that teachers who do not fully embrace inquiry science as a central teaching strategy tend to believe that it is not aligned with standardized tests and requires higher cognitive skills from students. Overall, the study seems to indicate that when inquiry is presented as a prescribed teaching approach, this elicits strong negative feelings/attitudes amongst science teachers, leading them not only to resist inquiry as a teaching tool, but also dissuading them from participating in science fair. Additionally, the findings suggest that such feelings among teachers could place the school at risk of not implementing inquiry science and science fair. In conclusion, the study reveals that science inquiry and science fair should not be prescribed to teachers as a top-down, mandatory approach for teaching science. In addition, the findings suggest that adequate teacher training in content knowledge and pedagogy in science inquiry and science fair should be encouraged, as this could help build a culture of science inquiry and implementation amongst teachers. This should go hand-in-hand with offering mentoring to science teachers new to inquiry and science fair for 2-5 years.

  5. Students' attitude-related responses to inquiry learning in undergraduate kinesiology laboratory instruction

    NASA Astrophysics Data System (ADS)

    Henige, Kimberly Ann

    The purpose of this investigation was to determine whether the student attitudes are impacted when teaching methods in an undergraduate Kinesiology lab course shift from a traditional, cookbook-style, low inquiry-level to an investigative, high inquiry-level approach. Students participated in five weeks of Level 0-1 (low) inquiry activities, followed by five weeks of a Level 3 (high) inquiry project. The same Likert-scale survey was administered to students before and after each 5-week period. The attitudes measured by the survey included students' (a) attitude to scientific inquiry, (b) adoption of scientific attitudes, (c) enjoyment of science lessons, and (d) motivation in science. Repeated measures ANOVAs revealed no significant change in any of the attitude measures when the survey results from the different time points were compared. An open-ended qualitative survey was given to the students at the end of the semester and provided more insight. When asked to compare the low and high-level inquiry experiences, most students reported enjoying the higher level of inquiry more. On the other hand, most students felt they learned more during the low inquiry-level activities. The reported level of motivation in lab was about the same for both levels. When asked what they liked most about the high-level inquiry project, students favored aspects such as the independence, responsibility, and personal relevance. When asked what they liked the least, most students said there was nothing they disliked. Of the minority of students who did not like the high-level of inquiry, most claimed to be uncomfortable with the lack of structure and guidance. Other findings were that many students expressed a new or increased respect and appreciation for what scientists do. Some students experienced a decrease in their reliance on science to be true and correct. While some students thought the high-level inquiry was harder, others perceived it as being easier. These findings illustrate

  8. Do individual differences in children's curiosity relate to their inquiry-based learning?

    NASA Astrophysics Data System (ADS)

    van Schijndel, Tessa J. P.; Jansen, Brenda R. J.; Raijmakers, Maartje E. J.

    2018-06-01

    This study investigates how individual differences in 7- to 9-year-olds' curiosity relate to the inquiry-learning process and outcomes in environments differing in structure. The focus on curiosity as individual differences variable was motivated by the importance of curiosity in science education, and uncertainty being central to both the definition of curiosity and the inquiry-learning environment. Curiosity was assessed with the Underwater Exploration game (Jirout, J., & Klahr, D. (2012). Children's scientific curiosity: In search of an operational definition of an elusive concept. Developmental Review, 32, 125-160. doi:10.1016/j.dr.2012.04.002), and inquiry-based learning with the newly developed Scientific Discovery task, which focuses on the principle of designing informative experiments. Structure of the inquiry-learning environment was manipulated by explaining this principle or not. As intelligence relates to learning and possibly curiosity, it was taken into account. Results showed that children's curiosity was positively related to their knowledge acquisition, but not to their quality of exploration. For low intelligent children, environment structure positively affected their quality of exploration, but not their knowledge acquisition. There was no interaction between curiosity and environment structure. These results support the existence of two distinct inquiry-based learning processes - the designing of experiments, on the one hand, and the reflection on performed experiments, on the other - and link children's curiosity to the latter process.

    A novel hand biometric authentication method based on measurements of the user's stationary hand gesture of hand sign language is proposed. The measurement of hand gestures could be sequentially acquired by a low-cost video camera. There could possibly be another level of contextual information, associated with these hand signs to be used in biometric authentication. As an analogue, instead of typing a password 'iloveu' in text which is relatively vulnerable over a communication network, a signer can encode a biometric password using a sequence of hand signs, 'i' , 'l' , 'o' , 'v' , 'e' , and 'u'. Subsequently the features from the hand gesture images are extracted which are integrally fuzzy in nature, to be recognized by a classification model for telling if this signer is who he claimed himself to be, by examining over his hand shape and the postures in doing those signs. It is believed that everybody has certain slight but unique behavioral characteristics in sign language, so are the different hand shape compositions. Simple and efficient image processing algorithms are used in hand sign recognition, including intensity profiling, color histogram and dimensionality analysis, coupled with several popular machine learning algorithms. Computer simulation is conducted for investigating the efficacy of this novel biometric authentication model which shows up to 93.75% recognition accuracy.

    Recently, we showed that 10 x 2% of consecutively patch-tested hand eczema patients had a positive patch test to a selection of fragrances containing fragrances relevant to hand exposure. In this study, we used repeated skin exposure to a patch test-positive fragrance allergen in patients previously diagnosed with hand eczema to explore whether immersion of fingers in a solution with or without the patch-test-positive fragrance allergen would cause or exacerbate hand eczema on the exposed finger. The study was double blinded and randomized. All participants had a positive patch test to either hydroxycitronellal or Lyral (hydroxyisohexyl 3-cyclohexene carboxaldehyde). Each participant immersed a finger from each hand, once a day, in a solution containing the fragrance allergen or placebo. During the first 2 weeks, the concentration of fragrance allergen in the solution was low (approximately 10 p.p.m.), whilst during the following 2 weeks, the concentration was relatively high (approximately 250 p.p.m.), imitating real-life exposure to a household product like dishwashing liquid diluted in water and the undiluted product, respectively. Evaluation was made using a clinical scale and laser Doppler flow meter. 3 of 15 hand eczema patients developed eczema on the finger immersed in the fragrance-containing solution, 3 of 15 on the placebo finger and 3 of 15 on both fingers. Using this experimental exposure model simulating real-life exposure, we found no association between immersion of a finger in a solution containing fragrance and development of clinically visible eczema on the finger in 15 participants previously diagnosed with hand eczema and with a positive patch test to the fragrance in question.

  17. Constructing inquiry: One school's journey to develop an inquiry-based school for teachers and students

    NASA Astrophysics Data System (ADS)

    Sisk-Hilton, Stephanie Lee

    This study examines the two way relationship between an inquiry-based professional development model and teacher enactors. The two year study follows a group of teachers enacting the emergent Supporting Knowledge Integration for Inquiry Practice (SKIIP) professional development model. This study seeks to: (a) identify activity structures in the model that interact with teachers' underlying assumptions regarding professional development and inquiry learning; (b) explain key decision points during implementation in terms of these underlying assumptions; and (c) examine the impact of key activity structures on individual teachers' stated belief structures regarding inquiry learning. Linn's knowledge integration framework facilitates description and analysis of teacher development. Three sets of tensions emerge as themes that describe and constrain participants' interaction with and learning through the model. These are: learning from the group vs. learning on one's own; choosing and evaluating evidence based on impressions vs. specific criteria; and acquiring new knowledge vs. maintaining feelings of autonomy and efficacy. In each of these tensions, existing group goals and operating assumptions initially fell at one end of the tension, while the professional development goals and forms fell at the other. Changes to the model occurred as participants reacted to and negotiated these points of tension. As the group engaged in and modified the SKIIP model, they had repeated opportunities to articulate goals and to make connections between goals and model activity structures. Over time, decisions to modify the model took into consideration an increasingly complex set of underlying assumptions and goals. Teachers identified and sought to balance these tensions. This led to more complex and nuanced decision making, which reflected growing capacity to consider multiple goals in choosing activity structures to enact. The study identifies key activity structures that

    This study aimed to establish a hand-to-hand (HH) model for bioelectrical impedance analysis (BIA) fat free mass (FFM) estimation by comparing with a standing position hand-to-foot (HF) BIA model and dual energy X-ray absorptiometry (DXA); we also verified the reliability of the newly developed model. A total of 704 healthy Chinese individuals (403 men and 301 women) participated. FFM (FFMDXA) reference variables were measured using DXA and segmental BIA. Further, regression analysis, Bland–Altman plots, and cross-validation (2/3 participants as the modeling group, 1/3 as the validation group; three turns were repeated for validation grouping) were conducted to compare tests of agreement with FFMDXA reference variables. In male participants, the hand-to-hand BIA model estimation equation was calculated as follows: FFMmHH = 0.537 h2/ZHH − 0.126 year + 0.217 weight + 18.235 (r2 = 0.919, standard estimate of error (SEE) = 2.164 kg, n = 269). The mean validated correlation coefficients and limits of agreement (LOAs) of the Bland–Altman analysis of the calculated values for FFMmHH and FFMDXA were 0.958 and −4.369–4.343 kg, respectively, for hand-to-foot BIA model measurements for men; the FFM (FFMmHF) and FFMDXA were 0.958 and −4.356–4.375 kg, respectively. The hand-to-hand BIA model estimating equation for female participants was FFMFHH = 0.615 h2/ZHH − 0.144 year + 0.132 weight + 16.507 (r2 = 0.870, SEE = 1.884 kg, n = 201); the three mean validated correlation coefficient and LOA for the hand-to-foot BIA model measurements for female participants (FFMFHH and FFMDXA) were 0.929 and −3.880–3.886 kg, respectively. The FFMHF and FFMDXA were 0.942 and −3.511–3.489 kg, respectively. The results of both hand-to-hand and hand-to-foot BIA models demonstrated similar reliability, and the hand-to-hand BIA models are practical for assessing FFM. PMID:27775642

    We developed a wilderness science education program for high school girls. The program offers opportunities for students to explore and learn about mountain glaciers and the alpine landscape through scientific field studies with geologists and glaciologists. Our purpose is to give students a feeling for the natural processes that create the alpine world and provide an environment that fosters the critical thinking necessary to all scientific inquiry. The program is currently being offered through the North Cascades Institute, a non-profit organization offering outdoor education programs for the general public. We lead eight girls for a weeklong expedition to the remote USGS South Cascade Glacier Research Station in Washington's North Cascades. For four days, we explore the glacier and the nearby alpine valleys. We encourage the girls to observe and think like scientists through making observations and inferences. They develop their own experiments to test ideas about glacier dynamics and geomorphology. In addition to scientific exploration, we engage the students in discussions about the philosophy of science and its role in our everyday lives. Our program exemplifies the success of hands-on, inquiry-based teaching in small groups for science education in the outdoors. The wilderness setting and single gender field team inspires young women's interest in science and provides a challenging environment that increases their physical and intellectual self-confidence.

    2014-12-01

    This presentation provides an overview of a hands-on modeling tool developed for students in civil engineering and earth science disciplines to help them learn the fundamentals of hydrologic processes, model calibration, sensitivity analysis, uncertainty assessment, and practice conceptual thinking in solving engineering problems. The toolbox includes two simplified hydrologic models, namely HBV-EDU and HBV-Ensemble, designed as a complement to theoretical hydrology lectures. The models provide an interdisciplinary application-oriented learning environment that introduces the hydrologic phenomena through the use of a simplified conceptual hydrologic model. The toolbox can be used for in-class lab practices and homework assignments, and assessment of students' understanding of hydrological processes. Using this modeling toolbox, students can gain more insights into how hydrological processes (e.g., precipitation, snowmelt and snow accumulation, soil moisture, evapotranspiration and runoff generation) are interconnected. The educational toolbox includes a MATLAB Graphical User Interface (GUI) and an ensemble simulation scheme that can be used for teaching more advanced topics including uncertainty analysis, and ensemble simulation. Both models have been administered in a class for both in-class instruction and a final project, and students submitted their feedback about the toolbox. The results indicate that this educational software had a positive impact on students understanding and knowledge of hydrology.

  5. Teacher Perceptions of Inquiry and STEM Education in Bangladesh

    NASA Astrophysics Data System (ADS)

    Shahidullah, Kazi K.

    This dissertation reports lower secondary science teachers perceptions of current practice in Dhaka, Bangladesh concerning inquiry and STEM Education in order to establish a baseline of data for reform of science education in Bangladesh. Bangladesh has been trying to incorporate inquiry-based science curricula since the 1970s. Over time, the science curricula also aligned with different international science education movements such as Science for All, Scientific Literacy, Science, Technology, and Society. Science, Technology, Engineering, and Mathematics (STEM) is the most recent science education movement in international science education. This study explored current practices and perceptions of lower secondary science teachers in order to establish a baseline of current practice so that future reform recommendations may be pursued and recommendations made for Bangladesh to overcome the inquiry-based challenges and to incorporate new STEM-based science education trends happening in the US and throughout the world. The study explored science teachers perceptions and readiness to transform their science classrooms based on self-reported survey. The survey utilized Likert-type scale with range 1 (very strongly disagree) to 6 (very strongly agree) among four hundred lower secondary science teachers, teacher training college faculty, and university faculty. The data is presented in four different categories: curriculum, instruction, assessment, and professional development. Results indicated that the participants understand and practice a certain level of inquiry in their science classrooms, though they do not have adequate professional development. Participants also stated that they do not have sufficient instructional materials and the curriculum is not articulated enough to support inquiry. On the other hand, the participants reported that they understand and practice a certain degree of inquiry and STEM-based science education, but they also state that the

  6. Effects of collaboration and inquiry on reasoning and achievement in biology

    Jensen, Jamie Lee

    The primary purpose of the present study was to compare the effectiveness of two collaborative grouping strategies and two instructional methods in terms of gains in reasoning ability and achievement in college biology. In order to do so, a quasi-experimental study was performed in which students were placed in one of four treatment conditions: heterogeneous grouping within inquiry instruction, homogeneous grouping within inquiry instruction, heterogeneous grouping within non-inquiry instruction, and homogeneous grouping within non-inquiry instruction. Students were placed in groups based on initial reasoning level. Reasoning levels and achievement gains were assessed at the end of the study. Results showed that within non-inquiry instruction, heterogeneous mean group scores were higher in both reasoning and achievement than homogeneous groups. In contrast, within inquiry instruction, homogeneous mean group scores were higher in both reasoning and achievement. Inquiry instruction, as a whole, significantly outperformed non-inquiry instruction in the development of reasoning ability. Within inquiry instruction, low-ability students had significantly greater reasoning gains when grouped homogeneously. These results support Piaget's developmental theory and contradict Vygotsky's developmental theory. These results also suggest that the success of one grouping strategy over another is highly dependent upon the nature of instruction, which may be a cause for such conflicting views on grouping strategies within the educational literature. In addition, inquiry instruction led to students having greater confidence in their reasoning ability as well as a more positive attitude toward collaboration. Instructional implications are discussed.

    2017-04-01

    Since students have lost their interest in school science, several student-centered approaches, such as using topics that are relevant for students, inquiry-based learning, and discussion-based learning have been implemented to attract pupils into science. However, the effect of these approaches was usually measured in small-scale research, and thus, the large-scale evidence supporting student-centered approaches in general use is insufficient. Accordingly, this study aimed to investigate the effect of student-centered approaches on students' interest and achievement by analyzing a large-scale data set derived from Program for International Student Assessment (PISA) 2006, to add evidence for advocating these approaches in school science, and to generalize the effects on a large population. We used Finnish PISA 2006 data, which is the most recent data that measures science literacy and that contains relevant variables for the constructs of this study. As a consequence of the factor analyses, four teaching methods were grouped as student-centered approaches (relevant topic-based, open and guided inquiry-based, and discussion-based approaches in school science) from the Finnish PISA 2006 sample. The structural equation modeling result indicated that using topics relevant for students positively affected students' interest and achievement in science. Guided inquiry-based learning was also indicated as a strong positive predictor for students' achievement, and its effect was also positively associated with students' interest. On the other hand, open inquiry-based learning was indicated as a strong negative predictor for students' achievement, as was using discussion in school science. Implications and limitations of the study were discussed.

    The Department of Neuroscience at the University of Minnesota and the Science Museum of Minnesota have developed and implemented a successful program for middle school (grades 5-8) science teachers and their students, called Brain Science on the Move. The overall goals have been to bring neuroscience education to underserved schools, excite students about science, improve their understanding of neuroscience, and foster partnerships between scientists and educators. The program includes BrainU, a teacher professional development institute; Explain Your Brain Assembly and Exhibit Stations, multimedia large-group presentation and hands-on activities designed to stimulate student thinking about the brain; Class Activities, in-depth inquiry-based investigations; and Brain Trunks, materials and resources related to class activities. Formal evaluation of the program indicated that teacher neuroscience knowledge, self-confidence, and use of inquiry-based strategies and neuroscience in their classrooms have increased. Participating teachers increased the time spent teaching neuroscience and devoted more time to "inquiry-based" teaching versus "lecture-based teaching." Teachers appreciated in-depth discussions of pedagogy and science and opportunities for collegial interactions with world-class researchers. Student interest in the brain and in science increased. Since attending BrainU, participating teachers have reported increased enthusiasm about teaching and have become local neuroscience experts within their school communities.

    NASA Astrophysics Data System (ADS)

    Hapgood, Susanna Elizabeth

    This interpretive case study describes a 10-day inquiry science program of study of motion down inclined planes during which a class of 21 second graders investigated scientific relationships such as mass and speed, speed and momentum, and mass and momentum via both text-based experiences ("second-hand investigations") and hands-on materials-based experiments ("first-hand investigations"). Data sources included over 11 hours of videotaped instruction in addition to children's written work, class-generated artifacts, and paper-and-pencil pre- and posttests. Content analyses informed by both sociocultural and developmental perspectives revealed that, in addition to a significant increase in pre- to posttest scores, children in the class engaged in several processes integral to inquiry, namely, (a) using data as evidence, (b) evaluating investigative procedures, and (c) making sense of multiple forms of representations. In addition, the study describes the range of and shifts in children's ideas about scientific relationships fundamental to developing an understanding of motion. Many children were observed to make causal attributions involving a relationship between two variables, such as the mass and momentum of a ball rolling down a ramp. Discussed are mediating factors such as the teacher's role in scaffolding the class's investigations and features of the innovative "scientists' notebook" texts, which were integral to the instruction. Also presented is evidence of first-hand and second-hand investigations working in concert to provide the elementary school students with rich opportunities to learn and to express their developing understandings of scientific ideas. This study provides a rare glimpse of primary-grade inquiry-based science instruction within a classroom context.

  19. How Select Groups of Preservice Science Teachers with Inquiry Orientations View Teaching and Learning Science through Inquiry

    NASA Astrophysics Data System (ADS)

    Ward, Peggy

    Although hailed as a powerful form of instruction, in most teaching and learning contexts, inquiry-based instruction is fraught with ambiguous and conflicting definitions and descriptions. Yet little has been written about the experiences preservice science teacher have regarding their learning to teach science through inquiry. This project sought to understand how select preservice secondary science teachers enrolled in three UTeach programs in Arkansas conceptualize inquiry instruction and how they rationalize its value in a teaching and learning context. The three teacher education programs investigated in this study are adoption sites aligned with the UTeach Program in Austin, TX that distinguishes itself in part by its inquiry emphasis. Using a mixed method investigation design, this study utilized two sources of data to explore the preservice science teachers' thinking. In the first phase, a modified version of the Pedagogy of Science teaching Tests (POSTT) was used to identify select program participants who indicated preferences for inquiry instruction over other instructional strategies. Secondly, the study used an open-ended questionnaire to explore the selected subjects' beliefs and conceptions of teaching and learning science in an inquiry context. The study also focused on identifying particular junctures in the prospective science teachers' education preparation that might impact their understanding about inquiry. Using a constant comparative approach, this study explored 19 preservice science teachers' conceptions about inquiry. The results indicate that across all levels of instruction, the prospective teachers tended to have strong student-centered teaching orientations. Except subjects in for the earliest courses, subjects' definitions and descriptions of inquiry tended toward a few of the science practices. More advanced subjects, however, expressed more in-depth descriptions. Excluding the subjects who have completed the program, multiple

    During the last few years, the curriculum of many dentistry schools in Germany has been reorganised. Two key aspects of the applied changes are the integration of up-to-date teaching methods and the promotion of interdisciplinarity. To support these efforts, an approach to fabricating individualised simulation models for hands-on courses employing 3D printing is presented. The models are based on real patients, thus providing students a more realistic preparation for real clinical situations. As a wide variety of dental procedures can be implemented, the simulation models can also contribute to a more interdisciplinary dental education. The data used for the construction of the models were acquired by 3D surface scanning. The data were further processed with 3D modelling software. Afterwards, the models were fabricated by 3D printing with the PolyJet technique. Three models serve as examples: a prosthodontic model for training veneer preparation, a conservative model for practicing dental bonding and an interdisciplinary model featuring carious teeth and an insufficient crown. The third model was evaluated in a hands-on course with 22 fourth-year dental students. The students answered a questionnaire and gave their personal opinion. Whilst the concept of the model received very positive feedback, some aspects of the implementation were criticised. We discuss these observations and suggest ways for further improvement. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Inquiry skills are skills that aperson needs in developing concepts, but the results of the study suggest that these skills haven’t yet been trained along with the development of concepts in science feeding, found the difficulties of students in building the concept scientifically. Therefore, this study aims to find ways that are effective in training inquiry skills trough Levels of Inquiry (LoI) learning. Experimental research with one group pretest-postest design, using non-random sampling samples in one of vocational high school in Cimahi obtained purposively 33 students of X class. The research using the inquiry skills test instrument in the form of 15questions multiple choice with reliability in very high category. The result of data processing by using the normalized gain value obtained an illustration that the ways developed in the LoI are considered effective trained inquiry skills in the middle category. Some of the ways LoI learning are considered effective in communicating aspects through discovery learning, predicting trough interactive demonstration, hypotheses through inquiry lesson, and interpreting data through inquiry lab, but the implementation of LoI learning in this study hasn’t found a way that is seen as effective for trespassing aspects of designing an experiment.

  5. A Web-Based Learning Support System for Inquiry-Based Learning

    NASA Astrophysics Data System (ADS)

    Kim, Dong Won; Yao, Jingtao

    The emergence of the Internet and Web technology makes it possible to implement the ideals of inquiry-based learning, in which students seek truth, information, or knowledge by questioning. Web-based learning support systems can provide a good framework for inquiry-based learning. This article presents a study on a Web-based learning support system called Online Treasure Hunt. The Web-based learning support system mainly consists of a teaching support subsystem, a learning support subsystem, and a treasure hunt game. The teaching support subsystem allows instructors to design their own inquiry-based learning environments. The learning support subsystem supports students' inquiry activities. The treasure hunt game enables students to investigate new knowledge, develop ideas, and review their findings. Online Treasure Hunt complies with a treasure hunt model. The treasure hunt model formalizes a general treasure hunt game to contain the learning strategies of inquiry-based learning. This Web-based learning support system empowered with the online-learning game and founded on the sound learning strategies furnishes students with the interactive and collaborative student-centered learning environment.

  6. Effect of hand sanitizer location on hand hygiene compliance.

    Cure, Laila; Van Enk, Richard

    2015-09-01

    Hand hygiene is the most important intervention to prevent infection in hospitals. Health care workers should clean their hands at least before and after contact with patients. Hand sanitizer dispensers are important to support hand hygiene because they can be made available throughout hospital units. The aim of this study was to determine whether the usability of sanitizer dispensers correlates with compliance of staff in using the sanitizer in a hospital. This study took place in a Midwest, 404-bed, private, nonprofit community hospital with 15 inpatient care units in addition to several ambulatory units. The usability and standardization of sanitizers in 12 participating inpatient units were evaluated. The hospital measured compliance of staff with hand hygiene as part of their quality improvement program. Data from 2010-2012 were analyzed to measure the relationship between compliance and usability using mixed-effects logistic regression models. The total usability score (P = .0046), visibility (P = .003), and accessibility of the sanitizer on entrance to the patient room (P = .00055) were statistically associated with higher observed compliance rates. Standardization alone showed no significant impact on observed compliance (P = .37). Hand hygiene compliance can be influenced by visibility and accessibility of dispensers. The sanitizer location should be part of multifaceted interventions to improve hand hygiene. Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc.

  7. A rights-based approach to science literacy using local languages: Contextualising inquiry-based learning in Africa

    NASA Astrophysics Data System (ADS)

    Babaci-Wilhite, Zehlia

    2017-06-01

    This article addresses the importance of teaching and learning science in local languages. The author argues that acknowledging local knowledge and using local languages in science education while emphasising inquiry-based learning improve teaching and learning science. She frames her arguments with the theory of inquiry, which draws on perspectives of both dominant and non-dominant cultures with a focus on science literacy as a human right. She first examines key assumptions about knowledge which inform mainstream educational research and practice. She then argues for an emphasis on contextualised learning as a right in education. This means accounting for contextualised knowledge and resisting the current trend towards de-contextualisation of curricula. This trend is reflected in Zanzibar's recent curriculum reform, in which English replaced Kiswahili as the language of instruction (LOI) in the last two years of primary school. The author's own research during the initial stage of the change (2010-2015) revealed that the effect has in fact proven to be counterproductive, with educational quality deteriorating further rather than improving. Arguing that language is essential to inquiry-based learning, she introduces a new didactic model which integrates alternative assumptions about the value of local knowledge and local languages in the teaching and learning of science subjects. In practical terms, the model is designed to address key science concepts through multiple modalities - "do it, say it, read it, write it" - a "hands-on" experiential combination which, she posits, may form a new platform for innovation based on a unique mix of local and global knowledge, and facilitate genuine science literacy. She provides examples from cutting-edge educational research and practice that illustrate this new model of teaching and learning science. This model has the potential to improve learning while supporting local languages and culture, giving local languages their

    Outreach informed by scientific research plays an important role in fostering interest in science by making science and scientists accessible, fun, and interesting. Developing an interest in science in young, elementary-aged students through outreach is a rewarding endeavor for researchers, in that audiences are usually receptive, requirements for broader impacts are met, and bonds are formed between researchers and members of their local and surrounding communities. Promoting such interest among young students is imperative not only for an individual researcher's own self interest, but also for the strength of American science and innovation moving forward, and is the responsibility of the current generation of scientists. Developing genuine and successful inquiry-based, hands-on activities for elementary-aged students is outside the expertise of many researchers. Partnering with an informal education learning center (i.e. science museum or after-school program) provides researchers with the expertise they might be lacking in such endeavors. Here, we present a series of polar-, engineering- and microbiology-themed hands-on activities that have been developed by researchers at a government lab in partnership with a local science museum. Through a series of workshops, the science education staff at the museum provided researchers with background and instruction on inquiry and hands-on activities, and then collaborated with the researchers to develop activities which were later demonstrated at the museum to museum-goers. Education staff provided feedback about the presentation of the activities for further refinement. The program provided an opportunity for researchers to develop fun, on-target and age-appropriate science activities for elementary-aged students, an audience for outreach, and enabled general public audiences the chance to interact with researchers and scientists in an informal setting.

    1998-06-01

    An important procedure in pediatrics is to determine the skeletal maturity of a patient from radiographs of the hand. There is great interest in the automation of this tedious and time-consuming task. We present a new method for the segmentation of the bones of the hand, which allows the assessment of the skeletal maturity with an appropriate database of reference bones, similar to the atlas based methods. The proposed algorithm uses an extended active contour model for the segmentation of the hand bones, which incorporates a-priori knowledge of shape and topology of the bones in an additional energy term. This `scene knowledge' is integrated in a complex hierarchical image model, that is used for the image analysis task.

  11. Can an Inquiry Approach Improve College Student Learning in a Teaching Laboratory?

    PubMed Central

    Cogan, John G.

    2009-01-01

    We present an inquiry-based, hands-on laboratory exercise on enzyme activity for an introductory college biology course for science majors. We measure student performance on a series of objective and subjective questions before and after completion of this exercise; we also measure performance of a similar cohort of students before and after completion of an existing, standard, “direct” exercise over the same topics. Although student performance on these questions increased significantly after completion of the inquiry exercise, it did not increase after completion of the control, standard exercise. Pressure to “cover” many complex topics as preparation for high-stakes examinations such as the Medical College Admissions Test may account for persistence of highly efficient, yet dubiously effective “cookbook” laboratory exercises in many science classes.

    The Department of Neuroscience at the University of Minnesota and the Science Museum of Minnesota have developed and implemented a successful program for middle school (grades 5–8) science teachers and their students, called Brain Science on the Move. The overall goals have been to bring neuroscience education to underserved schools, excite students about science, improve their understanding of neuroscience, and foster partnerships between scientists and educators. The program includes BrainU, a teacher professional development institute; Explain Your Brain Assembly and Exhibit Stations, multimedia large-group presentation and hands-on activities designed to stimulate student thinking about the brain; Class Activities, in-depth inquiry-based investigations; and Brain Trunks, materials and resources related to class activities. Formal evaluation of the program indicated that teacher neuroscience knowledge, self-confidence, and use of inquiry-based strategies and neuroscience in their classrooms have increased. Participating teachers increased the time spent teaching neuroscience and devoted more time to “inquiry-based” teaching versus “lecture-based teaching.” Teachers appreciated in-depth discussions of pedagogy and science and opportunities for collegial interactions with world-class researchers. Student interest in the brain and in science increased. Since attending BrainU, participating teachers have reported increased enthusiasm about teaching and have become local neuroscience experts within their school communities. PMID:17012205

    The case for inquiry-based, hands-on, meaningful science education continues to gain credence as an effective and appropriate pedagogical approach (Karukstis 2005; NSF 2000). An innovative community-based framework for science learning, hereinafter referred to as the Big Sky Model, successfully addresses these educational aims, guiding high school and tribal college students from rural areas of Montana and Idaho in their understanding of chemical, physical, and environmental health concepts. Students participate in classroom lessons and continue with systematic inquiry through actual field research to investigate a pressing, real-world issue: understanding the complex links between poor air quality and respiratory health outcomes. This article provides background information, outlines the procedure for implementing the model, and discusses its effectiveness as demonstrated through various evaluation tools. PMID:20428505

    2004-12-01

    Hands-on, inquiry-based, constructivist activity offers students a powerful way to explore, uncover and ultimately gain a feel for the nature of science. In order to make practicable a more genuine approach to learning astronomy, we have undertaken the development of hands-on (and eyes-on) materials that can be used in introductory undergraduate astronomy courses. These materials focus on light and optics. Over the past several years as part of Project LITE (Light Inquiry Through Experiments), we have developed a kit of optical materials that is integrated with a set of Java applets. The combined kit and software allows students to do actual experiments concerning geometrical optics, fluorescence, phosphorescence, polarization and other topics by making use of the photons that are emitted by their computer screens. We have also developed a suite of over 100 Flash applets that allow students to directly explore many aspects of visual perception. A major effort of the project concerns spectroscopy, since it is arguably the most important tool used by astronomers to disentangle the nature of the universe. It is also one of the most challenging subjects to teach in undergraduate astronomy courses. The spectroscopy component of Project LITE includes take-home laboratory materials and experiments that are integrated with web-based software. We have also developed a novel quantitative handheld binocular spectrometer (patent pending). Our major spectroscopic software is called the Spectrum Explorer (SPEX). It allows students to create, manipulate and explore all types of spectra including blackbody, power law, emission and absorption. We are now extending the SPEX capabilities to help students gain easy access to the astronomical spectra included in the NVO databases. All of the Project LITE software can be found http://lite.bu.edu. Project LITE is supported by Grant #DUE-0125992 from the NSF Division of Undergraduate Education.

    There are continuing educational and political debates about 'inquiry' versus 'direct' teaching of science. Traditional science instruction has been largely direct but in the US, recent national and state science education standards advocate inquiry throughout K-12 education. While inquiry-based instruction has the advantage of modelling aspects of the nature of real scientific inquiry, there is little unconfounded comparative research into the effectiveness and efficiency of the two instructional modes for developing science conceptual understanding. This research undertook a controlled experimental study comparing the efficacy of carefully designed inquiry instruction and equally carefully designed direct instruction in realistic science classroom situations at the middle school grades. The research design addressed common threats to validity. We report on the nature of the instructional units in each mode, research design, methods, classroom implementations, monitoring, assessments, analysis and project findings.

    2017-08-01

    In this paper, we explore middle school science teachers' learning of inquiry-based instructional strategies through reflection on practice teaching sessions during a summer enrichment program with middle level students. The reflection sessions were part of a larger year-long inquiry professional development program in which teachers learned science content and inquiry pedagogy. The program included a 2-week summer institute in which teachers participated in science content sessions, practice teaching to middle level students, and small group-facilitated reflection sessions on their teaching. For this study, data collection focused on teachers' recorded dialogue during the facilitator - run reflection sessions, the teachers' daily written reflections, a final written reflection, and a written reflection on a videotaped teaching session. We investigated the teachers' reflection levels and the themes teachers focused on during their reflection sessions. Teachers were found to reflect at various reflection levels, from simple description to a more sophisticated focus on how to improve student learning. Recurrent themes point to the importance of providing situated learning environments, such as the practice teaching with immediate reflection for teachers to have time to practice new instructional strategies and gain insight from peers and science educators on how to handle student learning issues.

    2014-02-01

    Research has demonstrated that simulation-based inquiry learning has significant advantages for learning outcomes when properly scaffolded. For successful learning in science with simulation-based inquiry, one needs to ascertain levels of background knowledge so as to support learners in making, evaluating and modifying hypotheses, conducting experiments and interpreting data, and to regulate the learning process. This case study examines the influence of scaffolded simulation-based inquiry learning on fifth-graders' (n = 21) models of the greenhouse effect. The pupils were asked to make annotated drawings about the greenhouse effect both before and after scaffolding through simulation-based instructional interventions. The data were analysed qualitatively to investigate the impact of the interventions on the representations that pupils used in their descriptions of the greenhouse effect. It was found that scaffolded simulation-based inquiry learning noticeably enriched the concepts pupils used in their representations leading to better understanding of the phenomenon. In many cases, the fifth graders produced quite sophisticated representations.

  11. The experiment editor: supporting inquiry-based learning with virtual labs

    NASA Astrophysics Data System (ADS)

    Galan, D.; Heradio, R.; de la Torre, L.; Dormido, S.; Esquembre, F.

    2017-05-01

    Inquiry-based learning is a pedagogical approach where students are motivated to pose their own questions when facing problems or scenarios. In physics learning, students are turned into scientists who carry out experiments, collect and analyze data, formulate and evaluate hypotheses, and so on. Lab experimentation is essential for inquiry-based learning, yet there is a drawback with traditional hands-on labs in the high costs associated with equipment, space, and maintenance staff. Virtual laboratories are helpful to reduce these costs. This paper enriches the virtual lab ecosystem by providing an integrated environment to automate experimentation tasks. In particular, our environment supports: (i) scripting and running experiments on virtual labs, and (ii) collecting and analyzing data from the experiments. The current implementation of our environment supports virtual labs created with the authoring tool Easy Java/Javascript Simulations. Since there are public repositories with hundreds of freely available labs created with this tool, the potential applicability to our environment is considerable.

    Brinson, James R.

    The current study compared the effects of virtual versus physical laboratory manipulatives on 84 undergraduate non-science majors' (a) conceptual understanding of density and (b) density-related inquiry skill acquisition. A pre-post comparison study design was used, which incorporated all components of an inquiry-guided classroom, except experimental mode, and which controlled for curriculum, instructor, instructional method, time spent on task, and availability of reference resources. Participants were randomly assigned to either a physical or virtual lab group. Pre- and post-assessments of conceptual understanding and inquiry skills were administered to both groups. Paired-samples t tests revealed a significant mean percent correct score increase for conceptual understanding in both the physical lab group (M = .103, SD = .168), t(38) = -3.82, p < .001, r = .53, two-tailed, and the virtual lab group (M = .084, SD = .177), t(44) = -3.20, p = .003, r = .43, two-tailed. However, a one-way ANCOVA (using pretest scores as the covariate) revealed that the main effect of lab group on conceptual learning gains was not significant, F(1, 81) = 0.081, p = .776, two-tailed. An omnibus test of model coefficients within hierarchical logistic regression revealed that a correct response on inquiry pretest scores was not a significant predictor of a correct post-test response, chi 2(1, N = 84) = 1.68, p = .195, and that when lab mode was added to the model, it did not significantly increase the model's predictive ability, chi2(2, N = 84) = 1.95, p = .377. Thus, the data in the current study revealed no significant difference in the effect of physical versus virtual manipulatives when used to teach conceptual understanding and inquiry skills related to density.

  15. The effect of inquiry based science instruction on student understanding

    Nail, Jessica Lynette

    According to the TIMSS Study (2007), the United States is falling behind in the subjects of math and science. In order for the students in the United States to develop scientific literacy and remain competitive globally, inquiry must be the priority when teaching science (NRC, 1996; AAAS, 1990). The main purpose of this research was to see if inquiry-based instruction in the science classroom had a significant effect on student understanding and retention of information in a rural school in Virginia. The effect of inquiry-based science instruction on gender was also examined. The researcher implemented a four-week, inquiry-based unit on Virginia Sol 6.7, written in the 5 E learning style to 358 sixth-grade students and compared their posttest gains and delayed posttest scores to a control group consisting of 268 students. The control group received traditional teaching methods. The results for the posttest gains produced a p = 0.01. Therefore, there was a significant difference in the experimental group, which received the treatment, when compared to the control group, which did not receive treatment. A t test was also used to compare the delayed test scores of the experimental group to the control group. The results showed a p < 0.0001 when comparing the experimental group, which received the four-week inquiry-based science instruction treatment, to the control, which did not receive the treatment. This t test showed a very highly significant difference between the experimental group and the control group. Based on these results, it is imperative that Virginia begin implementing inquiry-based instruction in the science classroom.

    This paper describes a multiple case study on open inquiry-based learning in primary schools. During open inquiry, teachers often experience difficulties in balancing support and transferring responsibility to pupils' own learning. To facilitate teachers in guiding open inquiry, we developed hard and soft scaffolds. The hard scaffolds consisted of documents with explanations and/or exercises regarding difficult parts of the inquiry process. The soft scaffolds included explicit references to and additional explanations of the hard scaffolds. We investigated how teacher implementation of these scaffolds contributed to pupils' self-directed learning during open inquiry. Four classes of pupils, aged 10-11, were observed while they conducted an inquiry lesson module of about 10 lessons in their classrooms. Data were acquired via classroom observations, audio recordings, and interviews with teachers and pupils. The results show that after the introduction of the hard scaffolds by the teacher, pupils were able and willing to apply them to their investigations. Combining hard scaffolds with additional soft scaffolding promoted pupils' scientific understanding and contributed to a shared guidance of the inquiry process by the teacher and her pupils. Our results imply that the effective use of scaffolds is an important element to be included in teacher professionalisation.

    The purpose of this study is to examine the effects of `environmental chemistry' elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers' (SSSTs) conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and technological pedagogical content knowledge (TPACK) levels. Within one group pre-test-post-test design, the study was conducted with 117 SSSTs (68 females and 49 males—aged 21-23 years) enrolled in an `environmental chemistry' elective course in the spring semester of 2011-2012 academic-years. Instruments for data collection comprised of Environmental Chemistry Conceptual Understanding Questionnaire, TPACK survey, and Chemistry Attitudes and Experiences Questionnaire. Significant increases in the SSSTs' conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and TPACK levels are attributed to the SSSTs learning how to use the innovative technologies in the contexts of the `environmental chemistry' elective course and teaching practicum. The study implies that the TESI model may serve a useful purpose in experimental science courses that use the innovative technologies. However, to generalize feasibility of the TESI model, it should be evaluated with SSSTs in diverse learning contexts.

  1. An investigation into the factors that motivate teachers to implement inquiry in the science classroom

    NASA Astrophysics Data System (ADS)

    Robbins, Beth Schieber

    Inquiry-based science teaching is an inductive approach to science instruction that originated in constructivist learning theory and requires students to be active participants in their own learning process. In an inquiry-based classroom, students actively construct their knowledge of science through hands-on, engaged practices and inquiry-based approaches. Inquiry-based teaching stands in contrast to more traditional forms of teaching that see students as empty vessels to be filled by the teacher with rote facts. Despite calls from the NSF, the NRC, and the AAAS for more inquiry-based approaches to teaching science, research has shown that many teachers still do not use inquiry-based approaches. Teachers have cited difficulties including lack of time, high-stakes testing, a shortage of materials, problems with school-wide logistics, rigid science curricula, student passivity, and lack of prerequisite skills. The objective of this mixed-methods study was to examine to what extent specific, identifiable personality traits contribute to the likelihood that a teacher will use inquiry in the science classroom, and what factors figure predominantly as teachers' reasons for implementing inquiry. The findings of the study showed that the null hypotheses were not rejected. However, reduced conscientiousness and increased openness may be significant in indicating why teachers use inquiry-based teaching methods and avenues for further research. In addition, the qualitative results aligned with previous findings that showed that lack of resources (e.g., time and money) and peer support act as powerful barriers to implementing inquiry-based teaching. Inquiry teachers are flexible, come to teaching as a second or third career, and their classrooms can be characterized as chaotic, fun, and conducive to learning through engagement. The study suggests changes in practice among administrators and teachers. With adjustments in methods and survey instruments, additional research

    Among the purposes of physics learning at high school is to master the physics concepts and cultivate scientific attitude (including critical attitude), develop inductive and deductive reasoning skills. According to Ennis et al., inductive and deductive reasoning skills are part of critical thinking. Based on preliminary studies, both of the competence are lack achieved, it is seen from student learning outcomes is low and learning processes that are not conducive to cultivate critical thinking (teacher-centered learning). One of learning model that predicted can increase mastery concepts and train CTS is inquiry learning model aided computer simulations. In this model, students were given the opportunity to be actively involved in the experiment and also get a good explanation with the computer simulations. From research with randomized control group pretest-posttest design, we found that the inquiry learning model aided computer simulations can significantly improve students' mastery concepts than the conventional (teacher-centered) method. With inquiry learning model aided computer simulations, 20% of students have high CTS, 63.3% were medium and 16.7% were low. CTS greatly contribute to the students' mastery concept with a correlation coefficient of 0.697 and quite contribute to the enhancement mastery concept with a correlation coefficient of 0.603.

    This study investigates the impact of collaborative reflections on teachers' inquiry teaching practices and identifies supportive actions relating to their professional development. Three science teachers in the same elementary school worked as a cooperative and collaborative group. They attended workshops and worked collaboratively through observing colleagues' teaching practices and discussing with university professors about their own inquiry teaching. The pre- and post-treatment classroom observations and comparisons of their teaching reveal that the three teachers were more focussed on asking inquiry-oriented questions in the post-treatment teaching. With additional qualitative data analysis, this study identified supportive resources of professional development. Workshop training sessions and sample unit served as the initiative agent in the beginning stage. Discussions with peers and reflective observation of peer teaching acted as a facilitative agent. Finally, student responses and researchers' on-site visit comments worked as a catalytic agent for their professional development.

    McMillan, Barbara Alexander

    2001-07-01

    Inquiry in school science, as conceived by the authors of the Common Framework of Science Learning Outcomes K--12, is dependent upon four areas of skills. These are the skills of initiating and planning, performing and recording, analysing and interpreting, and communication and teamwork that map onto what Hodson calls the five phases of scientific inquiry in school science: initiation, design and planning, performance, interpretation, and reporting and communicating. This study looked at initiation in a multiage (Grades 1--3) classroom, and the curriculum, design tools, and inquiry acts believed to be necessary precursors of design and planning phases whether the inquiry in which young children engage is archival or laboratory investigation. The curriculum was designed to build upon children's everyday biological knowledge and through a series of carefully organized lessons to help them to begin to build scientifically valid conceptual models in the area of animal life cycles. The lessons began with what is called benchmark-invention after the historical work of Robert Karplus and the contemporary work of Earl Hunt and Jim Minstrell. The introduction of a biological concept was followed by a series of exploration activities in which children were encouraged to apply the concept invented in the benchmark lesson. Enlargement followed. This was the instructional phase in which children were helped to establish scientifically valid relationships between the invented concept and other biological concepts. The pre-instruction and post-instruction interview data suggest that the enacted curriculum and sequence in which the biological knowledge was presented helped the nineteen children in the study to recognize the connections and regularities within the life cycles of the major groupings of animals, and to begin to build scientific biological conceptual models. It is, however, argued that everyday biology, in the form of the person analogy, acts as an obstacle to

    How do you get middle and high school students excited about scientific inquiry? Have them join a collaborative research team in Antarctica! A comprehensive education program brought ocean science, marine ecology, and climate change impact research to more than 950 students in 2014-15 to increase their exposure to and excitement of current research. The program was integrated into a collaborative research project, involving five universities, that worked to characterize the connection between ocean circulation, plankton distribution, penguin foraging behavior, and climate change around Palmer Station, Antarctica. The scientists and education team co-led a weeklong workshop to expose 22 teachers to the research science, build relationships among the teachers and scientists, and refine the program to most effectively communicate the research to their students. In the fall, teachers taught NGSS-aligned, hands-on, data-focused classroom lessons to provide their students the necessary content to understand the project hypotheses using multiple science practices. Through a professional science blog and live video calls from Antarctica, students followed and discussed the science teams work while they were in the field. To apply the science practices the students had learned about, they designed, conducted, and analyzed their own ocean-related, inquiry-based research investigation as the culminating component of the program (results were presented at a Student Research Symposium attended by the science team). Of their own choosing, roughly half of the students used raw data from the CONVERGE research (including krill, CODAR, penguin, and glider data) for their investigations. This presentation will focus on the evaluation results of the education program to identify the aspects that successfully engaged teachers and students with scientific inquiry, science practices, and authentic data as well as the replicability of this integrated scientist-teacher partnership and

    Purpose To compare the performance of a deep-learning bone age assessment model based on hand radiographs with that of expert radiologists and that of existing automated models. Materials and Methods The institutional review board approved the study. A total of 14 036 clinical hand radiographs and corresponding reports were obtained from two children's hospitals to train and validate the model. For the first test set, composed of 200 examinations, the mean of bone age estimates from the clinical report and three additional human reviewers was used as the reference standard. Overall model performance was assessed by comparing the root mean square (RMS) and mean absolute difference (MAD) between the model estimates and the reference standard bone ages. Ninety-five percent limits of agreement were calculated in a pairwise fashion for all reviewers and the model. The RMS of a second test set composed of 913 examinations from the publicly available Digital Hand Atlas was compared with published reports of an existing automated model. Results The mean difference between bone age estimates of the model and of the reviewers was 0 years, with a mean RMS and MAD of 0.63 and 0.50 years, respectively. The estimates of the model, the clinical report, and the three reviewers were within the 95% limits of agreement. RMS for the Digital Hand Atlas data set was 0.73 years, compared with 0.61 years of a previously reported model. Conclusion A deep-learning convolutional neural network model can estimate skeletal maturity with accuracy similar to that of an expert radiologist and to that of existing automated models. © RSNA, 2017 An earlier incorrect version of this article appeared online.

  12. Connecting Inquiry and Values in Science Education. An Approach Based on John Dewey's Philosophy

    NASA Astrophysics Data System (ADS)

    Lee, Eun Ah; Brown, Matthew J.

    2018-03-01

    Conducting scientific inquiry is expected to help students make informed decisions; however, how exactly it can help is rarely explained in science education standards. According to classroom studies, inquiry that students conduct in science classes seems to have little effect on their decision-making. Predetermined values play a large role in students' decision-making, but students do not explore these values or evaluate whether they are appropriate to the particular issue they are deciding, and they often ignore relevant scientific information. We explore how to connect inquiry and values, and how this connection can contribute to informed decision-making based on John Dewey's philosophy. Dewey argues that scientific inquiry should include value judgments and that conducting inquiry can improve the ability to make good value judgments. Value judgment is essential to informed, rational decision-making, and Dewey's ideas can explain how conducting inquiry can contribute to make an informed decision through value judgment. According to Dewey, each value judgment during inquiry is a practical judgment guiding action, and students can improve their value judgments by evaluating their actions during scientific inquiry. Thus, we suggest that students need an opportunity to explore values through scientific inquiry and that practicing value judgment will help informed decision-makings.

    For science learning to be successful, students must develop attitudes toward support future engagement with challenging social issues related to science. This is especially important for increasing participation of students from underrepresented populations. This study investigated how participation in inquiry-based biology laboratory classes affected students’ attitudes toward science, focusing on deaf, hard-of-hearing, and hearing signing students in bilingual learning environments (i.e., taught in American Sign Language and English). Analysis of reflection assignments and interviews revealed that the majority of students developed positive attitudes toward science and scientific attitudes after participating in inquiry-based biology laboratory classes. Attitudinal growth appears to be driven by student value of laboratory activities, repeated direct engagement with scientific inquiry, and peer collaboration. Students perceived that hands-on experimentation involving peer collaboration and a positive, welcoming learning environment were key features of inquiry-based laboratories, affording attitudinal growth. Students who did not perceive biology as useful for their majors, careers, or lives did not develop positive attitudes. Students highlighted the importance of the climate of the learning environment for encouraging student contribution and noted both the benefits and pitfalls of teamwork. Informed by students’ characterizations of their learning experiences, recommendations are made for inquiry-based learning in college biology. PMID:28188279

  15. A narrative inquiry into teaching physics as inquiry: An examination of in-service exemplars

    NASA Astrophysics Data System (ADS)

    Evans, Paige K.

    Studies show that teachers who have experienced inquiry are more likely to practice the inquiry method in their own classrooms (McDermott, 2007; Olson, 1995; Pereira, 2005; Windschitl, 2002). This study explores changes in science teachers' personal practical knowledge (Clandinin, 1986) after participating in a graduate level physics inquiry course and subsequent professional development throughout the school year. In addition, teacher participants were studied to determine the roadblocks they encountered when altering curriculum mandates in ways that would enable them to work with the inquiry method. The results of this course and subsequent professional development sessions were analyzed for the benefits of using the inquiry method to teacher learning and to ascertain whether the teacher participants would be more apt to employ the inquiry method in their own classrooms. Moreover, the results of this study were analyzed to inform my personal practice as a leader preparing undergraduate science teachers in the teachHOUSTON program as well as in my continuing work with in-service teachers. An inquiry course may be added to the teachHOUSTON course sequence, based on the discoveries unearthed by this thesis study. This research study is conducted as a narrative inquiry (Clandinin & Connelly, 1992, 2000; Craig, 2011; Polkinghorne, 1995) where story works as both a research method and a form of representation (Connelly & Clandinin, 1990). Narrative inquiry is strongly influenced by John Dewey (1938) who believed that one must rely on past experiences and knowledge to solve current and future problems and that life experience is in fact education. This study inquires into the narratives of two teachers who are teaching secondary science in public schools. These stories illuminate the teachers' lived experiences as they co-constructed curriculum with their students. The images of teacher as a curriculum maker vs. teacher as a curriculum implementer (Craig & Ross, 2008

  17. Science Teachers' Perceptions of the Relationship Between Game Play and Inquiry Learning

    NASA Astrophysics Data System (ADS)

    Mezei, Jessica M.

    The implementation of inquiry learning in American science classrooms remains a challenge. Teachers' perceptions of inquiry learning are predicated on their past educational experiences, which means outdated methods of learning may influence teachers' instructional approaches. In order to enhance their understanding and ultimately their implementation of inquiry learning, teachers need new and more relevant models. This study takes a preliminary step exploring the potential of game play as a valuable experience for science teachers. It has been proposed that game play and inquiry experiences can embody constructivist processes of learning, however there has been little work done with science teachers to systematically explore the relationship between the two. Game play may be an effective new model for teacher education and it is important to understand if and how teachers relate game playing experience and knowledge to inquiry. This study examined science teachers' game playing experiences and their perceptions of inquiry experiences and evaluated teacher's recognition of learning in both contexts. Data was collected through an online survey (N=246) and a series of follow-up interviews (N=29). Research questions guiding the study were: (1) What is the nature of the relationship between science teachers' game experience and their perceptions of inquiry? (2) How do teachers describe learning in and from game playing as compared with inquiry science learning? and (3) What is the range of similarities and differences teachers articulate between game play and inquiry experiences?. Results showed weak quantitative links between science teachers' game experiences and their perceptions of inquiry, but identified promising game variables such as belief in games as learning tools, game experiences, and playing a diverse set of games for future study. The qualitative data suggests that teachers made broad linkages in terms of parallels of both teaching and learning. Teachers

    Integration of technology, social learning and scientific models offers pedagogical opportunities for science education. A particularly interesting area is thermal science, where students often struggle with abstract concepts, such as heat. In taking on this conceptual obstacle, we explore how hand-held infrared (IR) visualization technology can strengthen students' understanding of thermal phenomena. Grounded in the Swedish physics curriculum and part of a broader research programme on educational uses of IR cameras, we have developed laboratory exercises around a thermal storyline, in conjunction with the teaching of a heat-flow model. We report a narrative analysis of how a group of five fourth-graders, facilitated by a researcher, predicts, observes and explains (POE) how the temperatures change when they pour hot water into a ceramic coffee mug and a thin plastic cup. Four chronological episodes are described and analysed as group interaction unfolded. Results revealed that the students engaged cognitively and emotionally with the POE task and, in particular, held a sustained focus on making observations and offering explanations for the scenarios. A compelling finding was the group's spontaneous generation of multiple "what-ifs" in relation to thermal phenomena, such as blowing on the water surface, or submerging a pencil into the hot water. This was followed by immediate interrogation with the IR camera, a learning event we label instant inquiry. The students' expressions largely reflected adoption of the heat-flow model. In conclusion, IR cameras could serve as an access point for even very young students to develop complex thermal concepts.

    Meade, Karen Marie

    The purpose of this study was to identify conceptual and attitudinal effects of inquiry learning in technology-based undergraduate chemistry laboratories. There were 428 participants who were registered in general chemistry laboratory at the University of Iowa in the Spring of 2002. Conceptual and attitudinal pretest and posttest results were quantitative in nature. Qualitative results were collected from questionnaires and focus groups. Quantitative data were analyzed using a repeated measures analysis of variance to identify differences between treatment groups. A high-inquiry treatment group was open-ended and required student decisions regarding data collection, data representation, and interpretation. The low-inquiry treatment involved collaboration and traditional learning strategies. Major findings of this study were: (1) Pretest to posttest conceptual gains were significant for both treatment groups. Low-inquiry students performed significantly better on exploration questions than high-inquiry students. (2) Process skills developed at higher levels for high-inquiry students than low-inquiry students. (3) Positive attitudes decreased significantly for all students from pretest to posttest. More favorable attitudes toward science enjoyment and the ability to do well in science were found for high-inquiry students. More favorable attitudes toward science enjoyment and the ability to do well in science were found for low-inquiry males and high-inquiry females. (4) More favorable attitudes toward the nature of science caused by use of the learning cycle were reported by high-inquiry students. (5) Low-inquiry students reported more favorable attitudes toward technologies in the laboratory than did high-inquiry students. Favorable attitudes toward the use of infrared spectrometers and unfavorable attitudes toward the use of pH meters were reported by both treatment groups. (6) More formal reasoning skills were reported by high-inquiry students. Both groups

    Lakin, Joni M.; Wallace, Carolyn S.

    2015-03-01

    Inquiry-based teaching promotes students' engagement in problem-solving and investigation as they learn science concepts. Current practice in science teacher education promotes the use of inquiry in the teaching of science. However, the literature suggests that many science teachers hold incomplete or incorrect conceptions of inquiry. Teachers, therefore, may believe they are providing more inquiry experiences than they are, reducing the positive impact of inquiry on science interest and skills. Given the prominence of inquiry in professional development experiences, educational evaluators need strong tools to detect intended use in the classroom. The current study focuses on the validity of assessments developed for evaluating teachers' use of inquiry strategies and classroom orientations. We explored the relationships between self-reported inquiry strategy use, preferences for inquiry, knowledge of inquiry practices, and related pedagogical content knowledge. Finally, we contrasted students' and teachers' reports of the levels of inquiry-based teaching in the classroom. Self-reports of inquiry use, especially one specific to the 5E instructional model, were useful, but should be interpreted with caution. Teachers tended to self-report higher levels of inquiry strategy use than their students perceived. Further, there were no significant correlations between either knowledge of inquiry practices or PCK and self-reported inquiry strategy use.

    2017-07-01

    To solve the problem that the accurate information of hand cannot be obtained by particle filter, a hand tracking algorithm based on particle filter combined with skin-color adaptive gradient vector flow (GVF) snake model is proposed. Adaptive GVF and skin color adaptive external guidance force are introduced to the traditional GVF snake model, guiding the curve to quickly converge to the deep concave region of hand contour and obtaining the complex hand contour accurately. This algorithm realizes a real-time correction of the particle filter parameters, avoiding the particle drift phenomenon. Experimental results show that the proposed algorithm can reduce the root mean square error of the hand tracking by 53%, and improve the accuracy of hand tracking in the case of complex and moving background, even with a large range of occlusion.

    To observe the effect of a rehabilitation intervention on the comprehensive health status of patients with hand burns. Most studies of hand-burn patients have focused on functional recovery. There have been no studies involving a biological-psychological-social rehabilitation model of hand-burn patients. A randomized controlled design was used. Patients with hand burns were recruited to the study, and sixty patients participated. Participants were separated into two groups: (1) The rehabilitation intervention model group (n=30) completed the rehabilitation intervention model, which included the following measures: enhanced social support, intensive health education, comprehensive psychological intervention, and graded exercise. (2) The control group (n=30) completed routine treatment. Intervention lasted 5 weeks. Analysis of variance (ANOVA) and Student's t test were conducted. The rehabilitation intervention group had significantly better scores than the control group for comprehensive health, physical function, psychological function, social function, and general health. The differences between the index scores of the two groups were statistically significant. The rehabilitation intervention improved the comprehensive health status of patients with hand burns and has favorable clinical application. The comprehensive rehabilitation intervention model used here provides scientific guidance for medical staff aiming to improve the integrated health status of hand-burn patients and accelerate their recovery.

    Baze, Christina L.

    Model-Based Inquiry (MBI) is an instructional model which engages students in the scientific practices of modeling, explanation, and argumentation while they work to construct explanations for natural phenomena. This instructional model has not been previously studied at the community college level. The purpose of this study is to better understand how MBI affects the development of community college students' conceptual understanding of evolution and engagement in the practices of science. Mixed-methods were employed to collect quantitative and qualitative data through the multiple-choice Concepts Inventory of Natural Selection, student artifacts, and semi-structured interviews. Participants were enrolled in Biology Concepts, an introductory class for non-science majors, at a small, rural community college in the southwestern United States. Preliminary data shows that conceptual understanding is not adversely affected by the implementation of MBI, and that students gain valuable insights into the practices of science. Specifically, students who participated in the MBI intervention group gained a better understanding of the role of models in explaining and predicting phenomena and experienced feeling ownership of their ideas, an appropriate depth of thinking, more opportunities for collaboration, and coherence and context within the unit. Implications of this study will be of interest to postsecondary science educators and researchers who seek to reform and improve science education.

  19. Improvement of Hand Movement on Visual Target Tracking by Assistant Force of Model-Based Compensator

    NASA Astrophysics Data System (ADS)

    Ide, Junko; Sugi, Takenao; Nakamura, Masatoshi; Shibasaki, Hiroshi

    Human motor control is achieved by the appropriate motor commands generating from the central nerve system. A test of visual target tracking is one of the effective methods for analyzing the human motor functions. We have previously examined a possibility for improving the hand movement on visual target tracking by additional assistant force through a simulation study. In this study, a method for compensating the human hand movement on visual target tracking by adding an assistant force was proposed. Effectiveness of the compensation method was investigated through the experiment for four healthy adults. The proposed compensator precisely improved the reaction time, the position error and the variability of the velocity of the human hand. The model-based compensator proposed in this study is constructed by using the measurement data on visual target tracking for each subject. The properties of the hand movement for different subjects can be reflected in the structure of the compensator. Therefore, the proposed method has possibility to adjust the individual properties of patients with various movement disorders caused from brain dysfunctions.

    2017-09-01

    The achievement of the subject of animal physiology requires that the students actively and creatively find their knowledge independently in understanding the concepts, theories, physiological processes, decompose, assemble, compare and modify physiological processes in relation to the fluctuation of environmental factors through practicum activities. The achievement of this lesson has not been fully realized because the learning resources used can’t guide, direct and make the independent students achieve their learning achievement and the practical handbook used has not been able to lead the students active and creative in finding their own knowledge. The practical handbook used so far consists only of the introduction of materials, work steps and questions. For that, we need to develop guided inquiry guide based on the needs of students. Objectives this study produces a practical handbook that fits the needs of the students. The research was done by using 4-D models and limited to define stage that is student requirement analysis. Data obtained from the questionnaire and analysed descriptively. The questionnaire obtained an average of 88.16%. So the needs of students will guide guided inquiry based inquiry both to be developed.

  1. The function of questions in Omani fourth grade inquiry-based science classrooms: A sociocultural perspective

    NASA Astrophysics Data System (ADS)

    Al-Shaibani, Madiha Ahmed

    2005-11-01

    Studies indicate that science education reforms are globally converging. Many countries are adopting the globally advocated science education reforms for the purpose of obtaining the competitive edge in science education and technology that are viewed as the driving forces of modern economies. Globally, science education reforms are emphasizing paradigm shifts in which constructivist instructional are foregrounded. Many science education curricular documents advocate teaching science through engaging students in scientific inquiry. As a result, science classrooms are becoming more student-centered where students are typically actively engaged in inquiry learning. Even though inquiry instruction has become the common approach in teaching science, the actual implementation of inquiry in classrooms indicates that there is a big gap between the intended inquiry advocated in curricula documents and the actual practices in classroom settings. One of the main features of inquiry instruction is student questions. Authentic student questions are essential for the initiating and main scientific inquiry. However, studies have also illustrated the rarity of student questions in classrooms. This dearth in student questions has been attributed to the discursive practices in classrooms. Classrooms that implement the traditional IRE discourse structure tend to have less student questions. On the other hand, reflective questioning is considered a more appropriate classroom discourse structure because it intentionally invites student questions and engages students in classroom discussions. This qualitative study addresses the issue of questioning in fourth grade inquiry-based science classrooms of the Omani Basic Education system. Methods employed in this study included: participant observation, individual interviews, focus group interviews and the collection of artifacts. Findings of this study illustrated the rarity of student questions in the classrooms. However this

    2012-10-01

    The performance of English language learners (ELLs) has been a concern given the rapidly changing demographics in US K-12 education. This study aimed to examine whether students' English language status has an impact on their inquiry science performance. Differential item functioning (DIF) analysis was conducted with regard to ELL status on an inquiry-based science assessment, using a multifaceted Rasch DIF model. A total of 1,396 seventh- and eighth-grade students took the science test, including 313 ELL students. The results showed that, overall, non-ELLs significantly outperformed ELLs. Of the four items that showed DIF, three favored non-ELLs while one favored ELLs. The item that favored ELLs provided a graphic representation of a science concept within a family context. There is some evidence that constructed-response items may help ELLs articulate scientific reasoning using their own words. Assessment developers and teachers should pay attention to the possible interaction between linguistic challenges and science content when designing assessment for and providing instruction to ELLs.

    The Enduring Resources for Earth Science Education (ERESE) Project bridges the gap between earth science research and science education by providing a forum for electronic collaboration between practicing scientists and classroom teachers. By combining the resources of Scripps Institution of Oceanography (SIO) and the expertise of educators, ERESE leverages a wide variety of assets to provide state-of-the-art, online digital resources through two National Science Digital Library collections: Earthref.org (http://www.Earthref.org/ERESE) and SIOExplorer (http://SIOExplorer.ucsd.edu). Earthref.org provides a wealth of plate tectonic-related content appropriate for designing and enacting inquiry lessons. The SIOExplorer Digital Library houses marine geophysical data from over 800 research cruises each containing a variety of data types from meteorological, to oceanographic, geophysical and navigational data. Built on successful collaboration between scientists and middle and high school teachers from across the country beginning in 2004, ERESE has expanded into a multifaceted repository for thought-provoking earth science data and images, virtual field trips and inquiry lessons designed by our partner teachers. More than static interfaces, both Earthref.org and SIOExplorer introduce users to current topics in science, seeking to answer outstanding questions about the earth, its processes, formation, and future. To provide a starting point for new users to design and contribute lessons to Earthref.org we have created a basic inquiry lesson plan template that models the process of investigating a real scientific problem. The template is designed on the basis of our five-stage model of inquiry adapted to the National Science Education Standards. As with all inquiry lessons, our model focuses on the shift of power from the teacher at the outset of the lesson to the students upon completion of the lesson.

    Incomprehension and denial of the theory of evolution among high school students has been observed to also occur when teachers are not equipped to deliver a compelling case also for human evolution based on fossil evidence. This paper assesses the outcomes of a novel inquiry-based paleoanthropology lab teaching human evolution to high-school students. The inquiry-based Be a Paleoanthropologist for a Day lab placed a dozen hominin skulls into the hands of high-school students. Upon measuring three variables of human evolution, students explain what they have observed and discuss findings. In the 2013/14 school year, 11 biology classes in 7 schools in the Greater New Orleans area participated in this lab. The interviewed teacher cohort unanimously agreed that the lab featuring hominin skull replicas and stimulating student inquiry was a pedagogically excellent method of delivering the subject of human evolution. First, the lab's learning path of transforming facts to data, information to knowledge, and knowledge to acceptance empowered students to themselves execute part of the science that underpins our understanding of deep time hominin evolution. Second, although challenging, the hands-on format of the lab was accessible to high-school students, most of whom were readily able to engage the lab's scientific process. Third, the lab's exciting and compelling pedagogy unlocked higher order thinking skills, effectively activating the cognitive, psychomotor and affected learning domains as defined in Bloom's taxonomy. Lastly, the lab afforded students a formative experience with a high degree of retention and epistemic depth. Further study is warranted to gauge the degree of these effects.

  14. Short-Term Research Experiences with Teachers in Earth and Planetary Sciences and a Model for Integrating Research into Classroom Inquiry

    NASA Astrophysics Data System (ADS)

    Morgan, P.; Bloom, J. W.

    2006-12-01

    For the past three summers, we have worked with in-service teachers on image processing, planetary geology, and earthquake and volcano content modules using inquiry methods that ended with mini-research experiences. Although almost all were science teachers, very few could give a reasonable definition of science at the start of the modules, and very few had a basic grasp of the processes of scientific research and could not include substantive scientific inquiry into their lessons. To build research understanding and confidence, an instructor-student interaction model was used in the modules. Studies have shown that children who participate in classrooms as learning and inquiry communities develop more complex understandings. The same patterns of complex understandings have resulted in similarly structured professional communities of teachers. The model is based on professional communities, emphasizing from the beginning that inquiry is a form of research. Although the actual "research" component of the modules was short, the teachers were identified as professionals and researchers from the start. Research/inquiry participation is therefore an excellent example by which to allow their teachers to learn. Initially the teachers were very reluctant to pose questions. As they were encouraged to share, collaborate, and support each other, the role of the instructor became less of a leader and more of a facilitator, and the confidence of the teachers as professionals and researchers grew. One teacher even remarked, "This is how we should be teaching our kids!' Towards the end of the modules the teachers were ready for their mini- research projects and collaborated in teams of 2-4. They selected their own research topics, but were guided toward research questions that required data collection (from existing studies), some data manipulation, interpretation, and drawing conclusions with respect to the original question. The teachers were enthusiastic about all of their

    participants to treatment and control groups and dependent pre- and post-tests (Shadish, Cook, & Campbell, 2002). Teacher and student NOS understanding was measured using the Student Understanding of Science and Science Inquiry (SUSSI) instrument (Liang, et. al, 2006). Science inquiry environment was measured with the Elementary Science Inquiry Survey (ESIS) (Dunbar, 2002) which was given both to teachers and their students. Science inquiry environment measurements were triangulated with observations of a stratified random sub-sample of participating teachers. Observations were structured using the low-inference Collaboratives for Excellence in Teaching Practice (CETP) Classroom Observation Protocol (COP) (Lawrenz, Huffman, & Appleldoorn 2002), and the high-inference Reform Teaching Observation Protocol (RTOP) (Piburn & Sawada, 2000). NBCTs possessed more informed view of NOS than did non-NBCTs. Additionally, high school science teachers possessed more informed views regarding NOS than did middle school science teachers, with the most informed views belonging to high school science NBCTs. High school science NBCTs created learning environments in which students engaged in science inquiry behaviors significantly more frequently than did high school science non-NBCTs. Middle school science NBCTs, on the other hand, did not create learning environments that differed in significant ways from those of middle school science non-NBCTs. Students of high school science NBCTs possessed significantly higher science reasoning than did students of high school science non-NBCTs. Middle school students of science NBCTs possessed no more science reasoning ability than did middle school students of science non-NBCTs. NOS understanding displayed by students of both middle school and high school science NBCTs was not distinguished from students of non-NBCTs.

  2. Practical inquiry/theory in nursing.

    PubMed

    Stevenson, Chris

    2005-04-01

    This paper explores a social constructionist, pragmatist approach to inquiry and theory-building with a view to exploring its relevance for nursing as a practical discipline. Positivist and postpositivist inquiry approaches in practical disciplines have produced "detached" theories that lack relevance for everyday practice and so sustain the theory-practice gap. Both meta- and mid-range theories tend to see practice as fixed or fixable rather than being enacted in a state of flux. Practical inquiry and theory are described structurally and as co-dependent processes. The research process is sensitive to the influence of context and consists of construction rather than capture. Practical theory is judged in terms of whether it helps people to "go on with" their lives. Practical inquiry/practical theory is superimposed on a previous nursing study in the field of mental health to illustrate how it can account for the processes of clinical research. In particular, the illustration demonstrates the surrender of researcher objectivity in the interests of collaborative understanding that occurs with practical inquiry/theory. Shared meaning arises as rich constructs of the research situation are developed that point to future possibilities for action for all those engaged in the research process. Practical inquiry/theory offers the means to conduct cogent, collaborative, developmental research, although further "trying out" is required.

    Background Recommended disease prevention behaviors of hand washing, hygienic hand drying, and covering one’s mouth and nose in a hygienic manner when coughing and sneezing appear to be simple behaviors but continue to be a challenge to successfully promote and sustain worldwide. We conducted a qualitative inquiry to better understand current hand drying behaviors associated with activities of daily living, and mouth and nose covering practices, among Kenyans. Methods and Findings We conducted 7 focus group discussions; 30 in-depth interviews; 10 structured household observations; and 75 structured observations in public venues in the urban area of Kisumu; rural communities surrounding Kisumu; and a peri-urban area outside Nairobi, Kenya. Using a grounded theory approach, we transcribed and coded the narrative data followed by thematic analysis of the emergent themes. Hand drying, specifically on a clean towel, was not a common practice among our participants. Most women dried their hands on their waist cloth, called a leso, or their clothes whether they were cooking, eating or cleaning the nose of a young child. If men dried their hands, they used their trousers or a handkerchief. Children rarely dried their hands; they usually just wiped them on their clothes, shook them, or left them wet as they continued with their activities. Many people sneezed into their hands and wiped them on their clothes. Men and women used a handkerchief fairly often when they had a runny nose, cold, or the flu. Most people coughed into the air or their hand. Conclusions Drying hands on dirty clothes, rags and lesos can compromise the benefits of handwashing. Coughing and sneezing in to an open hand can contribute to spread of disease as well. Understanding these practices can inform health promotion activities and campaigns for the prevention and control of diarrheal disease and influenza. PMID:24069302

  15. A Collective Case Study of Secondary Students' Model-Based Inquiry on Natural Selection through Programming in an Agent-Based Modeling Environment

    NASA Astrophysics Data System (ADS)

    Xiang, Lin

    This is a collective case study seeking to develop detailed descriptions of how programming an agent-based simulation influences a group of 8 th grade students' model-based inquiry (MBI) by examining students' agent-based programmable modeling (ABPM) processes and the learning outcomes. The context of the present study was a biology unit on natural selection implemented in a charter school of a major California city during spring semester of 2009. Eight 8th grade students, two boys and six girls, participated in this study. All of them were low socioeconomic status (SES). English was a second language for all of them, but they had been identified as fluent English speakers at least a year before the study. None of them had learned either natural selection or programming before the study. The study spanned over 7 weeks and was comprised of two study phases. In phase one the subject students learned natural selection in science classroom and how to do programming in NetLogo, an ABPM tool, in a computer lab; in phase two, the subject students were asked to program a simulation of adaptation based on the natural selection model in NetLogo. Both qualitative and quantitative data were collected in this study. The data resources included (1) pre and post test questionnaire, (2) student in-class worksheet, (3) programming planning sheet, (4) code-conception matching sheet, (5) student NetLogo projects, (6) videotaped programming processes, (7) final interview, and (8) investigator's field notes. Both qualitative and quantitative approaches were applied to analyze the gathered data. The findings suggested that students made progress on understanding adaptation phenomena and natural selection at the end of ABPM-supported MBI learning but the progress was limited. These students still held some misconceptions in their conceptual models, such as the idea that animals need to "learn" to adapt into the environment. Besides, their models of natural selection appeared to be

    Luberda, Michael

    2016-01-01

    Incomprehension and denial of the theory of evolution among high school students has been observed to also occur when teachers are not equipped to deliver a compelling case also for human evolution based on fossil evidence. This paper assesses the outcomes of a novel inquiry-based paleoanthropology lab teaching human evolution to high-school students. The inquiry-based Be a Paleoanthropologist for a Day lab placed a dozen hominin skulls into the hands of high-school students. Upon measuring three variables of human evolution, students explain what they have observed and discuss findings. In the 2013/14 school year, 11 biology classes in 7 schools in the Greater New Orleans area participated in this lab. The interviewed teacher cohort unanimously agreed that the lab featuring hominin skull replicas and stimulating student inquiry was a pedagogically excellent method of delivering the subject of human evolution. First, the lab’s learning path of transforming facts to data, information to knowledge, and knowledge to acceptance empowered students to themselves execute part of the science that underpins our understanding of deep time hominin evolution. Second, although challenging, the hands-on format of the lab was accessible to high-school students, most of whom were readily able to engage the lab’s scientific process. Third, the lab’s exciting and compelling pedagogy unlocked higher order thinking skills, effectively activating the cognitive, psychomotor and affected learning domains as defined in Bloom’s taxonomy. Lastly, the lab afforded students a formative experience with a high degree of retention and epistemic depth. Further study is warranted to gauge the degree of these effects. PMID:27513927

    2002-05-01

    : The purpose of this project is to find out which one of the antibacterial hand cleanser (antibacterial bar soap, antibacterial liquid hand soap, and liquid hand sanitizer) is more effective in eliminating microbes. If antibacterial- formula liquid hand soap is used on soiled hands, then it will be more effective in eliminating microbes. Germs are microorganisms that cause disease and can spread from person-to-person. Bacteria are a kind of microbe, an example of which is Transient Flora that is often found on hands. Hand washing prevents germs from spreading to others. During the procedure, swabs were used to take samples before and after the soiled hands had been washed with one of the antibacterial hand cleansers. Nutrient Easygel was poured into petri dishes to harden for 1 day, and then samples were swabbed on the gel. The Petri dishes were placed in an incubator for 24 hours, and then data was recorded accordingly. The antibacterial liquid hand soap was sufficient in eliminating the majority of bacteria. The hands had 65% of the bacteria on them, and after the liquid hand soap was used only 37% of the bacteria remained.

    Science education research has recommended cooperative inquiry based science in the primary science context for more than two decades but after more than 20 years, student achievement in science has not substantially improved. This study, through direct observation and analysis, investigated content-related student interactions in an authentic inquiry based primary science class setting. Thirty-one upper primary students were videotaped working in cooperative inquiry based science activities. Cooperative talk and negotiation of the science content was analysed to identify any high-level group interactions. The data show that while all groups have incidences of high-level content-related group interactions, the frequency and duration of these interactions were limited. No specific pattern of preceding events was identified and no episodes of high-level content-related group interactions were immediately preceded by the teacher's interactions with the groups. This in situ study demonstrated that even without any kind of scaffolding, specific skills in knowing how to implement cooperative inquiry based science, high-level content-related group interactions did occur very briefly. Support for teachers to develop their knowledge and skills in facilitating cooperative inquiry based science learning is warranted to ensure that high-level content-related group interactions and the associated conceptual learning are not left to chance in science classrooms.

    High profile accounts of failures in patient care reflect an urgent need for transformational development in healthcare. Appreciative Inquiry is promoted as an approach to exploring and bringing about change in social systems. Appreciative Inquiry has been used extensively in North American business since the late 1980s. The application of Appreciative Inquiry may have merit in the complex world of human health experiences. To identify, evaluate and synthesise the evidence about the impact of Appreciative Inquiry on changing clinical nursing practice in in-patient settings. An integrative review and narrative synthesis. In-patient settings including paediatrics, maternity and mental health. Nurses of all grades, patients, carers, relatives, other healthcare professionals including allied healthcare staff, management and students. An electronic search of the following electronic databases was performed in January 2015 and updated in July 2015: MEDLINE, EMBASE, Cochrane Library (Cochrane database of systematic reviews), Cumulative Index of Nursing and Allied Health Literature, PsychINFO, PsychARTICLES, Amed, Assia, Scopus and Web of Science. Hand searching of reference lists of included studies was undertaken. Limits were set to include literature published in English only and publications from 1990 to July 2015. Three reviewers independently assessed eligibility for inclusion and extracted data. Full text articles were systematically appraised using a standardised data extraction instrument in conjunction with criteria to assess whether change using Appreciative Inquiry is transformational. Eight studies (reported in 11 papers) met the inclusion criteria. Overall, these studies demonstrate poor application of Appreciative Inquiry criteria in a nursing context. This makes judgement of the impact difficult. One study achieved transformation against agreed criteria for Appreciative Inquiry. Other included studies demonstrated that Appreciative Inquiry is being

    Inquiry laboratory activity and scientific argumentation in science education should be promoted and explicitly experienced by prospective biology teacher students in classes, including in microbiology courses. The goal of this study is to get information about perceptions of prospective biology teachers on scientific argumentation in microbiology inquiry lab activities. This study reported the result of a survey research to prospective biology teachers about how their perception about microbiology lab classes and their perception about inquiry and argumentation in microbiology lab activities should be. The participants of this study were 100 students of biology education department from an institute in Cirebon, West Java taking microbiology lecture during the fifth semester. The data were collected using questionnaire to explore the perceptions and knowledge of prospective biology teachers about microbiology, inquiry lab activities and argumentation. The result showed that students thought that the difficulties of microbiology as a subject were the lack of references and the way lecturer teaching. The students’ perception was that argumentation and inquiry should be implemented in microbiology courses and lab activities. Based on the data from questionnaire, It showed that prospective biology teacher students had very little knowledge about scientific argumentation and its implementation in science education. When the participants made arguments based on the problems given, they showed low quality of arguments.

    Chemistry curriculum reform shows an explicit shift from traditional approach to scientific inquiry. This study aims to develop a guided inquiry-based laboratory worksheet on topic of heat of combustion. Implementation of this topic in high school laboratory is new because previously some teachers only focused the experiment on determining the heat of neutralization. The method used in this study was development research consisted of three stages: define, design, and develop. In the define stage, curriculum analysis and material analysis were performed. In the design stage, laboratory optimization and product preparation were conducted. In the development stage, the product was evaluated by the experts and tested to a total of 20 eleventh-grade students. The instruments used in this study were assessment sheet and students’ response questionnaire. The assessment results showed that the guided inquiry-based laboratory worksheet has very good quality based on the aspects of content, linguistic, and graphics. The students reacted positively to the use of this guided inquiry-based worksheet as demonstrated by the results from questionnaire. The implications of this study is the laboratory activity should be directed to development of scientific inquiry skills in order to enhance students’ competences as well as the quality of science education.

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

    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

    2016-05-01

    Integration of technology ( e.g. measuring with sensors, video measurement, and modeling) into secondary-school science teaching is a need globally recognized. A central issue of incorporating these technologies in teaching is how to turn manipulations of equipment and software into manipulations of ideas. Therefore, preparation for pre-service teachers to apply ICT tools should be combined with the issues of minds-on inquiring and meaning-making. From this perspective, we developed a course within the post-graduate teacher-education program in the Netherlands. During the course, pre-service teachers learnt not only to master ICT skills but also to design, teach, and evaluate an inquiry-based lesson in which the ICT tool was integrated. Besides three life sessions, teachers' learning scenario also consisted of individual tasks which teachers could carry out mostly in the school or at home with support materials and online assistance. We taught three iterations of the course within a design-research framework in 2013, 2014 and collected data on the teacher learning processes and outcomes. The analyses of these data from observation, interviews, questionnaires, and documents were to evaluate implementation of the course, then suggest for revisions of the course set-up, which was executed and then assessed again in a subsequent case study. Main outcomes of the three case studies can be summarized as follows: within a limited time (3 life sessions spread over 2-3 months), the heterogeneous groups of pre-service teachers achieved a reasonable level of competence regarding the use of ICT tools in inquiry-based lessons. The blended set-up with support materials, especially the Coach activities and the lesson-plan form for an ICT-integrated inquiry-based lesson, contributed to this result under the condition that the course participants really spent considerable time outside the life sessions. There was a need for more time for hands-on, in-group activities in life

  8. Bring the Poles to Your Classroom & Community Through Linked Hands-on Learning & IPY Data

    2009-12-01

    Two major legacies of the 4th International Polar Year (IPY 2007-9) are a newly galvanized educational community and an immense volume of polar data collected by the global science community. The tremendous new polar datasets represent a unique opportunity to communicate the nature of the changing poles to student and public audiences through this polar savvy educational community if effective approaches to link data and understanding are employed. We have developed a strategy for polar education that leverages the IPY data resources, linked with the polar education hands-on ‘manipulatives’ (materials that students can manipulate in a dynamic manner). This linked approach leverages the fundamental inquiry based learning but recognizes that particularly in the polar sciences the size of the earth, the remoteness of the poles and the scale of its processes make it difficult for students to explore in a hands-on manner. The linking of polar hands-on ‘manipulatives’ with IPY data provides a bridge between the tangible and the global. Alone manipulative activities can be beneficial in their ability to help students visualize a process or behavior, but without a strong link back to the Earth through data or evidence the understanding of the process is not transferred from the classroom model to the full scale Earth. The use of activities or models is beneficial in connecting the learner to the polar process(es), while the IPY data provides a unique opportunity to ground the polar manipulative experiments in real data. This linked strategy emerged from a series of NSF sponsored IPY Polar Fairs at major science museums that reached in excess of 12,000 people. The design of the fairs was that polar scientists developed activities linking low cost hands-on manipulatives to scientific evidence/data that was displayed in posters, images, and video clips. The participating scientists walked the ‘audience’ through the hands-on manipulative, then discussed their

    Demir, Abdulkadir

    The purpose of this phenomenographic study was to: (a) understand how beginning science teachers recruited from various science disciplines and prepared in an Alternative Teacher Certification Program (ATCP) implemented inquiry during their initial years of teaching; (b) describe constraints and needs that these beginning science teachers perceived in implementing inquiry-based science instruction; and (c) understand the relation between what they learned in their ATCP and their practice of teaching science through inquiry. The participants of this study consisted of four ATCP teachers who are in their beginning years of teaching. Semi-structured interviews, classroom observation, field notes, and artifacts used as source of data collection. The beginning science teachers in this study held incomplete views of inquiry. These views of inquiry did not reflect inquiry as described in NRC (2000)---essential features of inquiry,---nor did they reflect views of faculty members involved in teaching science methods courses. Although the participants described themselves as reform-oriented, there were inconsistencies between their views and practices. Their practice of inquiry did not reflect inquiry either as outlined by essential features of inquiry (NRC, 2000) or inquiry as modeled in activities used in their ATCP. The research participants' perceived constraints and needs in their implementation of inquiry-based activities. Their perceived constraints included logistical and student constraints and school culture. The perceived needs included classroom management, pedagogical skills, practical knowledge, discipline, successful grade-specific models of inquiry, and access to a strong support system. Prior professional work experience, models and activities used in the ATCP, and benefits of inquiry to student learning were the declared factors that facilitated the research participants' practice of inquiry-based teaching.

  12. Linking Science Inquiry Skills in a Holistic Approach.

    Gabel, Connie

    The quest for the inclusion of science inquiry in the curriculum now spans three centuries. In the late 1800s and early 1900s, Armstrong, Dewey, and others espoused the teaching of science inquiry. The launch of Sputnik in 1957 began the strong emphasis on inquiry. Renewed interest in inquiry occurred in the late 1980s and 1990s with science…

  19. The Connection Between Forms of Guidance for Inquiry-Based Learning and the Communicative Approaches Applied—a Case Study in the Context of Pre-service Teachers

    NASA Astrophysics Data System (ADS)

    2017-09-01

    Recent research has argued that inquiry-based science learning should be guided by providing the learners with support. The research on guidance for inquiry-based learning has concentrated on how providing guidance affects learning through inquiry. How guidance for inquiry-based learning could promote learning about inquiry (e.g. epistemic practices) is in need of exploration. A dialogic approach to classroom communication and pedagogical link-making offers possibilities for learners to acquire these practices. The focus of this paper is to analyse the role of different forms of guidance for inquiry-based learning on building the communicative approach applied in classrooms. The data for the study comes from an inquiry-based physics lesson implemented by a group of five pre-service primary science teachers to a class of sixth graders. The lesson was video recorded and the discussions were transcribed. The data was analysed by applying two existing frameworks—one for the forms of guidance provided and another for the communicative approaches applied. The findings illustrate that providing non-specific forms of guidance, such as prompts, caused the communicative approach to be dialogic. On the other hand, providing the learners with specific forms of guidance, such as explanations, shifted the communication to be more authoritative. These results imply that different forms of guidance provided by pre-service teachers can affect the communicative approach applied in inquiry-based science lessons, which affects the possibilities learners are given to connect their existing ideas to the scientific view. Future research should focus on validating these results by also analysing inservice teachers' lessons.

    Surgical cameras are prevalent in modern operating theatres and are often used as a surrogate for direct vision. Visualisation techniques (e.g. image fusion) made possible by tracking the camera require accurate hand-eye calibration between the camera and the tracking system. The authors introduce the concept of 'guided hand-eye calibration', where calibration measurements are facilitated by a target registration error (TRE) model. They formulate hand-eye calibration as a registration problem between homologous point-line pairs. For each measurement, the position of a monochromatic ball-tip stylus (a point) and its projection onto the image (a line) is recorded, and the TRE of the resulting calibration is predicted using a TRE model. The TRE model is then used to guide the placement of the calibration tool, so that the subsequent measurement minimises the predicted TRE. Assessing TRE after each measurement produces accurate calibration using a minimal number of measurements. As a proof of principle, they evaluated guided calibration using a webcam and an endoscopic camera. Their endoscopic camera results suggest that millimetre TRE is achievable when at least 15 measurements are acquired with the tracker sensor ∼80 cm away on the laparoscope handle for a target ∼20 cm away from the camera.

    2000-10-01

    Radio Jove is a relatively new educational project to involve secondary school students in collecting and analyzing observations of the natural radio emissions of the planet Jupiter and the Sun. Participating students get hands-on experience in gathering and working with space science data. They obtain the data by either building a radio receiver and antenna and making observations with their equipment, or by remotely using professional radio telescopes through the web. They can then compare their results with other schools who had also observed and come to conclusions concerning the nature of the radio sources and how the radio waves propagate to Earth. Thus, they fully follow the method of scientific inquiry used by radio astronomers to study our solar system. (National Science Content Standard A: Science as Inquiry) More than 200 kits have been distributed thus far to schools and individuals as a result of the project. With the coming Cassini flyby of Jupiter we will be advocating a campaign in which many of the schools involved in the project will be observing at times of scientific interest. While Galileo and Cassini are monitoring Jovian radio emissions at lower frequencies, the schools will be observing at frequencies of 20.1 MHz (kit-based observations) or the frequencies available through the professional radio telescopes connected on-line. The aim will be to get a thorough picture of the levels of activity at Jupiter during the flyby period and how the radio signals are received at different observing stations around the world. An archive of observations submitted by the schools will be maintained at Goddard Space Flight Center and there will also be an archive of the professional telescopes data at the University of Florida. We hope that many students will have the feeling of being a part of the planetary exploration program as a result.

    Inquiry-based instruction in biology has been the focus of educational research conducted by Unnes biology department students in collaboration with their university supervisors. This study aimed to describe the methodological aspects, inquiry teaching methods critically, and to analyse the results claims, of the selected four student research reports, grounded in inquiry, based on the database of Unnes biology department 2014. Four experimental quantitative research of 16 were selected as research objects by purposive sampling technique. Data collected through documentation study was qualitatively analysed regarding methods used, quality of inquiry syntax, and finding claims. Findings showed that the student research was still the lack of relevant aspects of research methodology, namely in appropriate sampling procedures, limited validity tests of all research instruments, and the limited parametric statistic (t-test) not supported previously by data normality tests. Their consistent inquiry syntax supported the four mini-thesis claims that inquiry-based teaching influenced their dependent variables significantly. In other words, the findings indicated that positive claims of the research results were not fully supported by good research methods, and well-defined inquiry procedures implementation.

  6. The effect of concept mapping on preservice elementary teachers' knowledge of science inquiry teaching

    Jackson, Diann Carol

    This study examined the effect of concept mapping as a method of stimulating reflection on preservice elementary teachers' knowledge of science inquiry instruction methods. Three intact classes of science education preservice teachers participated in a non-randomized comparison group with a pretest and posttest design to measure the influence of mapping on participants' knowledge of inquiry science instruction. All groups followed the same course syllabus, in class activities, readings, assignments and assessment tasks. The manner in which they presented their ideas about inquiry science teaching varied. Groups constructed pre-lesson, post-lesson, and homework lists or maps across three inquiry based instruction modules (ecosystems, food chains, and electricity). Equivalent forms of the Teaching Science Inventory (TSI) were used to investigate changes in preservice teachers' propositional knowledge about how to teach using inquiry science instruction methods. Equivalent forms of the Science Lesson Planning (SLP) test were used to investigate changes in preservice teachers' application knowledge about how to teach using inquiry science instruction methods. Data analysis included intrarater reliability, ANOVAs, ANCOVAs, and correlations between lists and maps and examination responses. SLP and TSI scores improved from the pretest to the posttest in each of the three study groups. The results indicate that, in general, there were basically no relationships between the treatment and outcome measures. In addition, there were no significant differences between the three groups in their knowledge about how to teach science. Conclusions drawn from this study include, first, the learners did learn how to teach science using inquiry. Second, in this study there is little evidence to support that concept mapping was more successful than the listing strategy in improving preservice elementary teachers' knowledge of teaching science using inquiry science instruction methods.

    2014-07-01

    Learning science through the process of inquiry is advocated in curriculum documents across many jurisdictions. However, a number of studies suggest that teachers struggle to help students engage in inquiry practices. This is not surprising as many teachers of science have not engaged in scientific inquiry and possibly hold naïve ideas about what constitutes scientific inquiry. This study investigates teachers' self-reported approaches to teaching science through inquiry. Phenomenographic interviews undertaken with 20 elementary teachers revealed teachers identified six approaches to teaching for inquiry, clustered within three categories. These approaches were categorized as Free and Illustrated Inquiries as part of an Experience-centered category, Solution and Method Inquiries as part of a Problem-centered category, and Topic and Chaperoned Inquiries as part of a Question-centered category. This study contributes to our theoretical understanding of how teachers approach Inquiry Teaching and suggests fertile areas of future research into this valued and influential phenomenon broadly known as 'Inquiry Teaching'.

    NASA Astrophysics Data System (ADS)

    Tissenbaum, Michael

    This design-based study describes the implementation and evaluation of a technology framework to support smart classrooms and Distributed Technology Enhanced Learning (DTEL) called SAIL Smart Space (S3). S3 is an open-source technology framework designed to support students engaged in inquiry investigations as a knowledge community. To evaluate the effectiveness of S3 as a generalizable technology framework, a curriculum named PLACE (Physics Learning Across Contexts and Environments) was developed to support two grade-11 physics classes (n = 22; n = 23) engaged in a multi-context inquiry curriculum based on the Knowledge Community and Inquiry (KCI) pedagogical model. This dissertation outlines three initial design studies that established a set of design principles for DTEL curricula, and related technology infrastructures. These principles guided the development of PLACE, a twelve-week inquiry curriculum in which students drew upon their community-generated knowledge base as a source of evidence for solving ill-structured physics problems based on the physics of Hollywood movies. During the culminating smart classroom activity, the S3 framework played a central role in orchestrating student activities, including managing the flow of materials and students using real-time data mining and intelligent agents that responded to emergent class patterns. S3 supported students' construction of knowledge through the use individual, collective and collaborative scripts and technologies, including tablets and interactive large-format displays. Aggregate and real-time ambient visualizations helped the teacher act as a wondering facilitator, supporting students in their inquiry where needed. A teacher orchestration tablet gave the teacher some control over the flow of the scripted activities, and alerted him to critical moments for intervention. Analysis focuses on S3's effectiveness in supporting students' inquiry across multiple learning contexts and scales of time, and in

    Zalles, D. R.; Montgomery, D. R.

    2008-12-01

    Place-based field work has been recognized as an important component of geoscience education programs for engaging students. Field work helps students appreciate the spatial extent of data and the systems operating in a locale. Data collected in a place has a temporal aspect that can be explored through representations such as photographs and maps and also though numerical data sets that capture characteristics of place. Yet, experiencing authentic geoscience research in an educational setting requires going beyond fieldwork: students must develop data literacy skills that will enable them to connect abstract representations of spatio-temporal data with place. Educational researchers at SRI International led by Dr. Daniel Zalles, developer of inquiry-based geoscience curricula, and geoscientists at the University of Washington (UW) led by Dr. David Montgomery, Professor of Earth and Space Sciences, are building educational curriculum modules that help students make these connections. The modules concern the environmental history of the Puget Sound area in Washington State and its relevance for the American Indians living there. This collaborative project relies on environmental data collected in the Puget Sound Regional Synthesis Model (PRISM) and Puget Sound River History Project. The data sets are being applied to inquiry-based geoscience investigations at the undergraduate and high school level. The modules consist of problem-based units centered on the data sets, plus geographic and other data representations. The modules will rely on educational "design patterns" that characterize geoscientific inquiry tasks. Use of design patterns will enable other modules to be built that align to the modes of student thinking and practice articulated in the design patterns. The modules will be accompanied by performance assessments that measure student learning from their data investigations. The design principles that drive this project have already been used effectively

  13. Registration-based segmentation with articulated model from multipostural magnetic resonance images for hand bone motion animation.

    2010-06-01

    The quantitative measurements of hand bones, including volume, surface, orientation, and position are essential in investigating hand kinematics. Moreover, within the measurement stage, bone segmentation is the most important step due to its certain influences on measuring accuracy. Since hand bones are small and tubular in shape, magnetic resonance (MR) imaging is prone to artifacts such as nonuniform intensity and fuzzy boundaries. Thus, greater detail is required for improving segmentation accuracy. The authors then propose using a novel registration-based method on an articulated hand model to segment hand bones from multipostural MR images. The proposed method consists of the model construction and registration-based segmentation stages. Given a reference postural image, the first stage requires construction of a drivable reference model characterized by hand bone shapes, intensity patterns, and articulated joint mechanism. By applying the reference model to the second stage, the authors initially design a model-based registration pursuant to intensity distribution similarity, MR bone intensity properties, and constraints of model geometry to align the reference model to target bone regions of the given postural image. The authors then refine the resulting surface to improve the superimposition between the registered reference model and target bone boundaries. For each subject, given a reference postural image, the proposed method can automatically segment all hand bones from all other postural images. Compared to the ground truth from two experts, the resulting surface image had an average margin of error within 1 mm (mm) only. In addition, the proposed method showed good agreement on the overlap of bone segmentations by dice similarity coefficient and also demonstrated better segmentation results than conventional methods. The proposed registration-based segmentation method can successfully overcome drawbacks caused by inherent artifacts in MR images and

    This research aims at producing a good quality learning device using guided inquiry for comparison topics and describing the effectiveness of guided inquiry learning for comparison topics. This research is a developmental research using 4-D model. The result is learning device consisting of lesson plan, student’s worksheet, and achievement test. The subjects of the study were class VII students, each of which has 46 students. Based on the result in the experimental class, the learning device using guided inquiry for comparison topics has good quality. The learning device has met the valid, practical, and effective aspects. The result, especially in the implementation class, showed that the learning process with guided inquiry has fulfilled the effectiveness indicators. The ability of the teacher to manage the learning process has fulfilled the criteria good. In addition, the students’ activity has fulfilled the criteria of, at least, good. Moreover, the students’ responses to the learning device and the learning activities were positive, and the students were able to complete the classical learning. Based on the result of this research, it is expected that the learning device resulted can be used as an alternative learning device for teachers in implementing mathematic learning for comparison topics.

  15. The effect of guided inquiry-based instruction in secondary science for students with learning disabilities

    NASA Astrophysics Data System (ADS)

    Eliot, Michael H.

    Students with learning disabilities (SWLDs) need to attain academic rigor to graduate from high school and college, as well as achieve success in life. Constructivist theories suggest that guided inquiry may provide the impetus for their success, yet little research has been done to support this premise. This study was designed to fill that gap. This quasi-experimental study compared didactic and guided inquiry-based teaching of science concepts to secondary SWLDs in SDC science classes. The study examined 38 students in four classes at two diverse, urban high schools. Participants were taught two science concepts using both teaching methods and posttested after each using paper-and-pencil tests and performance tasks. Data were compared to determine increases in conceptual understanding by teaching method, order of teaching method, and exposure one or both teaching methods. A survey examined participants' perceived self-efficacy under each method. Also, qualitative comparison of the two test formats examined appropriate use with SWLDs. Results showed significantly higher scores after the guided inquiry method on concept of volume, suggesting that guided inquiry does improve conceptual understanding over didactic instruction in some cases. Didactic teaching followed by guided inquiry resulted in higher scores than the reverse order, indicating that SWLDs may require direct instruction in basic facts and procedures related to a topic prior to engaging in guided inquiry. Also application of both teaching methods resulted in significantly higher scores than a single method on the concept of density, suggesting that SWLDs may require more in depth instruction found using both methods. No differences in perceived self-efficacy were shown. Qualitative analysis both assessments and participants' behaviors during testing support the use of performance tasks over paper-and-pencil tests with SWLDs. Implications for education include the use of guided inquiry to increase SWLDs

    2010-12-01

    Science and technology are widely recognized as major drivers of innovation and industry (e.g. Rising above the Gathering Storm, 2006). While the focus for education reform is on school improvement, there is considerable research that supports the role that out-of-school experiences can play in student achievement and public understanding of STEM disciplines. Libraries provide an untapped resource for engaging underserved youth and their families in fostering an appreciation and deeper understanding of science and technology topics. Designed spaces, like libraries, allow lifelong, life-wide, and life-deep learning to take place though the research basis for learning in libraries is not as developed as other informal settings like science centers. The Space Science Institute’s National Center for Interactive Learning (NCIL) in partnership with the American Library Association (ALA), the Lunar and Planetary Institute (LPI), and the National Girls Collaborative Project (NGCP) have received funding from NSF to develop a national education project called the STAR Library Education Network: a hands-on learning program for libraries and their communities (or STAR-Net for short). STAR stands for Science-Technology, Activities and Resources. The overarching goal of the project is to reach underserved youth and their families with informal STEM learning experiences. This project will deepen our knowledge of informal/lifelong learning that takes place in libraries and establish a learning model that can be compared to the more established free-choice learning model for science centers and museums. The project includes the development of two STEM hands-on exhibits on topics that are of interest to library staff and their patrons: Discover Earth and Discover Tech. In addition, the project will produce resources and inquiry-based activities that libraries can use to enrich the exhibit experience. Additional resources will be provided through partnerships with relevant

  17. An educational ethnography of teacher-developed science curriculum implementation: Enacting conceptual change-based science inquiry with Hispanic students

    NASA Astrophysics Data System (ADS)

    Brunsell, Eric Steven

    An achievement gap exists between White and Hispanic students in the United States. Research has shown that improving the quality of instruction for minority students is an effective way to narrow this gap. Science education reform movements emphasize that science should be taught using a science inquiry approach. Extensive research in teaching and learning science also shows that a conceptual change model of teaching is effective in helping students learn science. Finally, research into how Hispanic students learn best has provided a number of suggestions for science instruction. The Inquiry for Conceptual Change model merges these three research strands into a comprehensive yet accessible model for instruction. This study investigates two questions. First, what are teachers' perceptions of science inquiry and its implementation in the classroom? Second, how does the use of the Inquiry for Conceptual Change model affect the learning of students in a predominantly Hispanic, urban neighborhood. Five teachers participated in a professional development project where they developed and implemented a science unit based on the Inquiry for Conceptual Change model. Three units were developed and implemented for this study. This is a qualitative study that included data from interviews, participant reflections and journals, student pre- and post-assessments, and researcher observations. This study provides an in-depth description of the role of professional development in helping teachers understand how science inquiry can be used to improve instructional quality for students in a predominantly Hispanic, urban neighborhood. These teachers demonstrated that it is important for professional development to be collaborative and provide opportunities for teachers to enact and reflect on new teaching paradigms. This study also shows promising results for the ability of the Inquiry for Conceptual Change model to improve student learning.

    This study explores the effects of metacognitive and cognitive prompting on the scientific inquiry practices of students with various levels of initial metacognition. Two junior high school classes participated in this study. One class, the experimental group (n = 26), which received an inquiry-based curriculum with a combination of cognitive and metacognitive prompts, was compared to the other class, the comparison group (n = 25), which received only cognitive prompts in the same curriculum. Data sources included a test of inquiry practices, a questionnaire of metacognition, and worksheets. The results showed that the mixed cognitive and metacognitive prompts had significant impacts on the students' inquiry practices, especially their planning and analyzing abilities. Furthermore, the mixed prompts appeared to have a differential effect on those students with lower level metacognition, who showed significant improvement in their inquiry abilities. A combination of cognitive and metacognitive prompts during an inquiry cycle was found to promote students' inquiry practices.

    The purpose of this quantitative investigation was to describe the extent to which secondary science teachers, who were certified through Connecticut's BEST portfolio assessment process between 1997 and 2004 and had taught secondary science during the past academic year, reported practicing the indicators of inquiry-based instruction in the classroom and the factors that they perceived facilitated, obstructed, or informed that practice. Indicators of inquiry-based instruction were derived from the Biological Sciences Curriculum Study (BSCS) 5E model (Bybee, 1997). The method for data collection was a researcher-developed, self-report, questionnaire entitled "Inquiry-based Instruction in Secondary Science Classrooms: A Survey", which was developed and disseminated using a slightly modified Dillman (2000) approach. Almost all of the study participants reported practicing the 5Es (engage, explore, explain, elaborate, and evaluate) of inquiry-based instruction in their secondary science classrooms. Time, resources, the need to cover material for mandatory assessments, the science topics or concepts being taught, and professional development on inquiry-based instruction were reported to be important considerations in participants' decisions to practice inquiry-based instruction in their science classrooms. A majority of the secondary science teachers participating in this study indicated they had the time, access to resources and the professional development opportunities they needed to practice inquiry-based instruction in their secondary classrooms. Study participants ranked having the time to teach in an inquiry-based fashion and the need to cover material for mandated testing as the biggest obstacles to their practice of inquiry-based instruction in the secondary classroom. Classroom experience and collegial exchange informed the inquiry-based instruction practice of the secondary science teachers who participated in this study. Recommendations for further research

    Parse, Rosemarie Rizzo

    2016-10-01

    The purpose of this article is to introduce the language for the mode of inquiry, now known as Parsesciencing. The language for the Humanbecoming Hermeneutic Sciencing was introduced in an earlier volume of Nursing Science Quarterly. Language both reflects and cocreates meaning. The language of sciencing is everchanging; it is an evolutionary emergent, shifting as new ideas cocreate horizons beyond. The language set forth here is to articulate more explicitly meanings of the modes of inquiry consistent with the humanbecoming paradigm and distinct from modes of inquiry in other disciplines. In dwelling with the findings of published and unpublished studies that were guided by humanbecoming, new insights arose, and with creative conceptualizing these new insights gave birth to new meanings, thus different language. The language introduced here includes the following: Parsesciencing as coming to know the meanings of universal humanuniverse living experiences, horizon of inquiry, foreknowings, inquiry stance, mode of inquiry, historians, dialoging-engaging, scholar, distilling-fusing, discerning extant moment, transmogrifying, transsubstantiating, and newknowings. Note: an example of the new language with a Parsesciencing inquiry on the universal humanuniverse living experience of feeling unsure by Sandra Bunkers appears later in this issue. © The Author(s) 2016.

    The objectives of the Computational Hand Modeling project were to prove the feasibility of the Laboratory`s NIKE3D finite element code to orthopaedic problems. Because of the great complexity of anatomical structures and the nonlinearity of their behavior, we have focused on a subset of joints of the hand and lower extremity and have developed algorithms to model their behavior. The algorithms developed here solve fundamental problems in computational biomechanics and can be expanded to describe any other joints of the human body. This kind of computational modeling has never successfully been attempted before, due in part to a lack ofmore » biomaterials data and a lack of computational resources. With the computational resources available at the National Laboratories and the collaborative relationships we have established with experimental and other modeling laboratories, we have been in a position to pursue our innovative approach to biomechanical and orthopedic modeling.« less

    2014-12-01

    The hand-held 3D laser scanner sold in the market is appealing for its port and convenient to use, but price is expensive. To develop such a system based cheap devices using the same principles as the commercial systems is impossible. In this paper, a simple hand-held 3D laser scanner is developed based on a volume reconstruction method using cheap devices. Unlike convenient laser scanner to collect point cloud of an object surface, the proposed method only scan few key profile curves on the surface. Planar section curve network can be generated from these profile curves to construct a volume model of the object. The details of design are presented, and illustrated by the example of a complex shaped object.

  15. Do science coaches promote inquiry-based instruction in the elementary science classroom?

    NASA Astrophysics Data System (ADS)

    Wicker, Rosemary Knight

    The South Carolina Mathematics and Science Coaching Initiative established a school-based science coaching model that was effective in improving instruction by increasing the level of inquiry-based instruction in elementary science classrooms. Classroom learning environment data from both teacher groups indicated considerable differences in the quality of inquiry instruction for those classrooms of teachers supported by a science coach. All essential features of inquiry were demonstrated more frequently and at a higher level of open-ended inquiry in classrooms with the support of a science coach than were demonstrated in classrooms without a science coach. However, from teacher observations and interviews, it was determined that elementary schoolteacher practice of having students evaluate conclusions and connect them to current scientific knowledge was often neglected. Teachers with support of a science coach reported changes in inquiry-based instruction that were statistically significant. This mixed ethnographic study also suggested that the Mathematics and Science Coaching Initiative Theory of Action for Instructional Improvement was an effective model when examining the work of science coaches. All components of effective school infrastructure were positively impacted by a variety of science coaching strategies intended to promote inquiry. Professional development for competent teachers, implementation of researched-based curriculum, and instructional materials support were areas highly impacted by the work of science coaches.

  18. Digging up your dirt. High school students combine small-scale respiration and soil carbon measurements with satellite imagery in hands-on inquiry activities.

    NASA Astrophysics Data System (ADS)

    Kemper, K.; Throop, H.

    2015-12-01

    One of the greatest impacts on the global carbon cycle is changes in land use. Making this concept relevant and inquiry-based for high school students is challenging. Many are familiar with reconstructing paleo-climate from ice core data, but few have a connection to current climate research. Many students ask questions like 'What will our area be like in 20 years?' or 'How much does planting trees help?' while few have the scientific language to engage in a discussion to answer these questions. Our work connects students to climate change research in several ways: first, teacher Keska Kemper engaged in field research with Dr. Heather Throop creating a 'teacher in the field' perspective for students in the classroom. Dr. Throop met with Keska Kemper's students several times to develop an inquiry-based field study. Students predicted and then measured rates of respiration between different soil types in an urban park close to their school. Students then could compare their results from Portland, Oregon to Throop's work across a rain gradient in Australia. Discussions about percent tree cover and soil carbon helped students see connections between land use changes and changes in carbon cycling. Last, students examined satellite imagery to determine percent tree cover and numberss of trees to compare to soil carbon in the same region. Students were able to examine imagery over the last 30 years to visualize land use changes in the greater Portland area.

  19. Supporting Teachers' Understanding of Nature of Science and Inquiry Through Personal Experience and Perception of Inquiry as a Dynamic Process

    NASA Astrophysics Data System (ADS)

    Zion, Michal; Schwartz, Renee S.; Rimerman-Shmueli, Esther; Adler, Idit

    2018-05-01

    One of today's challenges in science education involves the development of appropriate conceptions of inquiry teaching and realizing how these experiences can support students' understanding of the nature of science and inquiry (NOS and NOSI). To meet this challenge, we developed a course for in-service science teachers, in which explicit-reflective instruction of NOS was coupled with an open inquiry process. This process included documentation tools adjusted to emphasize the dynamic, logical, and reflective aspects of scientific inquiry. Teachers' documentations, reflections, and questionnaires were examined for indications of perceptual connection between comprehending the essence of dynamic open inquiry and understanding certain NOS tenets. The results indicated that the in-service teachers experienced all criteria of dynamic open inquiry, however not to the same extent. By focusing on four teachers who clearly addressed changes in their perspective of NOS and NOSI, we were able to examine the nature of those changes, and relate them to the teachers' personal experiences and perceptions of the characteristics of dynamic open inquiry. Our results suggest that the participants' personal experiences and perceptions of the dynamic characteristics of open inquiry play a crucial role in shaping their understanding of NOS and NOSI. The findings of this research underscore the importance of enhancing teachers' personal experiences and perceptions of the dynamic characteristics of open inquiry, as a vehicle to improve their understanding of NOS and NOSI.

    Nikolaev, E. I.; Dvoryaninov, P. V.; Lensky, Y. Y.; Drozdovsky, N. S.

    2018-05-01

    Deep learning has shown real promise for the classification efficiency for hand gesture recognition problems. In this paper, the authors present experimental results for a deeply-trained model for hand gesture recognition through the use of hand images. The authors have trained two deep convolutional neural networks. The first architecture produces the hand position as a 2D-vector by input hand image. The second one predicts the hand gesture class for the input image. The first proposed architecture produces state of the art results with an accuracy rate of 89% and the second architecture with split input produces accuracy rate of 85.2%. In this paper, the authors also propose using virtual data for training a supervised deep model. Such technique is aimed to avoid using original labelled images in the training process. The interest of this method in data preparation is motivated by the need to overcome one of the main challenges of deep supervised learning: using a copious amount of labelled data during training.

    The aim of this research was to obtain an overview of the increase scientific literacy attitudes domain in high school students as the effects of the Levels of Inquiry (LOI) model of science teaching. This research using a quasi-experimental methods and randomizedpretest-posttest control group design. The subject of this research was students of grade X in a senior high school in Purwakarta and it consists of two classes who were divided into experimental class (30 students) and control class (30 students). While experimental class was taught LOIand control class was taught Interactive Lecture Demonstration (ILD). Data were collected using an attitude scale scientific literacy test which is based on the Likert scale. Data were analyzed using normality test, homogeneity test, and t-test to the value of N-gain attitude of scientific literacy scale test. The result of percentage average N-gain experimental class and control are 49 and 31 that classified into medium improvement category. Based on the results of hypothesis testing on the N-gain value obtained by the Sig.(One-tailed) 0.000 < 0.050, it means that H1 was accepted. The results showed that scientific literacy domain attitude of students who got learning by LOI is higher than students who got learning by ILD. It can be concluded that the effect of LOI is better to improve scientific literacy domain attitudes significantly.

  12. Impact of backwards faded scaffolding approach to inquiry-based astronomy laboratory experiences on undergraduate non-science majors' views of scientific inquiry

    NASA Astrophysics Data System (ADS)

    Lyons, Daniel J.

    This study explored the impact of a novel inquiry-based astronomy laboratory curriculum designed using the Backwards Faded Scaffolding inquiry teaching framework on non-science majoring undergraduate students' views of the nature of scientific inquiry (NOSI). The study focused on two aspects of NOSI: The Distinction between Data and Evidence (DvE), and The Multiple Methods of Science (MMS). Participants were 220 predominately non-science majoring undergraduate students at a small, doctoral granting, research-extensive university in the Rocky Mountain region of the United States. The student participants were enrolled in an introductory astronomy survey course with an associated laboratory section and were selected in two samples over consecutive fall and spring semesters. The participants also included four of the graduate student instructors who taught the laboratory courses using the intervention curriculum. In the first stage, student participant views of NOSI were measured using the VOSI-4 research instrument before and after the intervention curriculum was administered. The responses were quantified, and the distributions of pre and posttest scores of both samples were separately analyzed to determine if there was a significant improvement in understanding of either of the two aspects of NOSI. The results from both samples were compared to evaluate the consistency of the results. In the second stage, the quantitative results were used to strategically design a qualitative investigation, in which the four lab instructors were interviewed about their observations of how the student participants interacted with the intervention curriculum as compared to traditional lab activities, as well as their suggestions as to how the curriculum may or may not have contributed to the results of the first stage. These interviews were summarized and analyzed for common themes as to how the intervention curriculum influenced the students' understandings of the two aspect of

    The purpose of this research is to describe the effectiveness of guided inquiry-based learning material to improve students’ science literacy skills on solubility and solubility product concepts. This study used Research and Development (R&D) design and was implemented to the 11th graders of Muhammadiyah 4 Senior High School Surabaya in 2016/2017 academic year with one group pre-test and post-test design. The data collection techniques used were validation, observation, test, and questionnaire. The results of this research showed that the students’ science literacy skills are different after implementation of guided inquiry-based learning material. The guided inquiry-based learning material is effective to improve students’ science literacy skills on solubility and solubility product concepts by getting N-gain score with medium and high category. This improvement caused by the developed learning material such as lesson plan, student worksheet, and science literacy skill tests were categorized as valid and very valid. In addition, each of the learning phases in lesson plan has been well implemented. Therefore, it can be concluded that the guided inquiry-based learning material are effective to improve students’ science literacy skills on solubility and solubility product concepts in senior high school.

  14. Supporting inquiry learning by promoting normative understanding of multivariable causality

    NASA Astrophysics Data System (ADS)

    Keselman, Alla

    2003-11-01

    Early adolescents may lack the cognitive and metacognitive skills necessary for effective inquiry learning. In particular, they are likely to have a nonnormative mental model of multivariable causality in which effects of individual variables are neither additive nor consistent. Described here is a software-based intervention designed to facilitate students' metalevel and performance-level inquiry skills by enhancing their understanding of multivariable causality. Relative to an exploration-only group, sixth graders who practiced predicting an outcome (earthquake risk) based on multiple factors demonstrated increased attention to evidence, improved metalevel appreciation of effective strategies, and a trend toward consistent use of a controlled comparison strategy. Sixth graders who also received explicit instruction in making predictions based on multiple factors showed additional improvement in their ability to compare multiple instances as a basis for inferences and constructed the most accurate knowledge of the system. Gains were maintained in transfer tasks. The cognitive skills and metalevel understanding examined here are essential to inquiry learning.

  15. Predictive models to determine imagery strategies employed by children to judge hand laterality.

    PubMed

    Spruijt, Steffie; Jongsma, Marijtje L A; van der Kamp, John; Steenbergen, Bert

    2015-01-01

    A commonly used paradigm to study motor imagery is the hand laterality judgment task. The present study aimed to determine which strategies young children employ to successfully perform this task. Children of 5 to 8 years old (N = 92) judged laterality of back and palm view hand pictures in different rotation angles. Response accuracy and response duration were registered. Response durations of the trials with a correct judgment were fitted to a-priori defined predictive sinusoid models, representing different strategies to successfully perform the hand laterality judgment task. The first model predicted systematic changes in response duration as a function of rotation angle of the displayed hand. The second model predicted that response durations are affected by biomechanical constraints of hand rotation. If observed data could be best described by the first model, this would argue for a mental imagery strategy that does not involve motor processes to solve the task. The second model reflects a motor imagery strategy to solve the task. In line with previous research, we showed an age-related increase in response accuracy and decrease in response duration in children. Observed data for both back and palm view showed that motor imagery strategies were used to perform hand laterality judgments, but that not all the children use these strategies (appropriately) at all times. A direct comparison of response duration patterns across age sheds new light on age-related differences in the strategies employed to solve the task. Importantly, the employment of the motor imagery strategy for successful task performance did not change with age.

    2017-09-01

    Laboratory activity is an important part of chemistry learning, but cookbook instructions is still commonly used. However, the activity with that way do not improve students thinking skill, especially students creativity. This study aims to improve high school students creativity through inquiry-based laboratory on drugs analysis activity. Acid-base titration is used to be method for drugs analysis involving a color changing indicator. The following tools were used to assess the activity achievement: creative thinking test on acid base titration, creative attitude and action observation sheets, questionnaire of inquiry-based lab activities, and interviews. The results showed that the inquiry-based laboratory activity improving students creative thinking, creative attitude and creative action. The students reacted positively to this teaching strategy as demonstrated by results from questionnaire responses and interviews. This result is expected to help teachers to overcome the shortcomings in other laboratory learning.

    NASA Astrophysics Data System (ADS)

    Shope, R. E.; Alcantara Valverde, L.

    2007-05-01

    A recent National Academy of Sciences report recommends that science educators focus strategically on teaching the practice of science. To accomplish this, we have devised and implemented the Science Performance Laboratory, a collaborative research, education, and workforce model that brings scientists and science educators together to conduct scientific inquiry. In this session, we demonstrate how to form active inquiry teams around Arctica Science Research content areas related to the International Polar Year. We use the term "Arctica Science Research" to refer to the entire scope of exploration and discovery relating to: polar science and its global connections; Arctic and Antarctic research and climate sciences; ice and cryospheric studies on Earth; polar regions of the Moon, Mars, and Mercury; icy worlds throughout the Solar System, such as Europa, Enceladus, Titan, Pluto and the Comets; cryovolcanism; ice in interstellar space, and beyond. We apply the notion of teaching the practice science by enacting three effective strategies: 1) The Inquiry Wheel Game, in which we develop an expanded understanding of what has been traditionally taught as "the scientific method"; 2) Acting Out the Science Story, in which we develop a physicalized expression of our conceptual understanding; and 3) Selecting Success Criteria for Inquiry Coaching, in which we reframe how we evaluate science learning as we teach the practice of science.

    The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to cover a more comprehensive construct of inquiry abilities and target secondary school students in different grades while this potential is leveraged. We implemented five steps derived from the construct modeling approach to design MASIA. During the implementation, multiple sources of evidence were collected in the steps of pilot testing and Rasch modeling to support the validity of MASIA. Particularly, through the participation of 1,066 8th and 11th graders, MASIA showed satisfactory psychometric properties to discriminate students with different levels of inquiry abilities in 101 items in 29 tasks when Rasch models were applied. Additionally, the Wright map indicated that MASIA offered accurate information about students' inquiry abilities because of the comparability of the distributions of student abilities and item difficulties. The analysis results also suggested that MASIA offered precise measures of inquiry abilities when the components (questioning, experimenting, analyzing, and explaining) were regarded as a coherent construct. Finally, the increased mean difficulty thresholds of item responses along with three performance levels across all sub-abilities supported the alignment between our scoring rubrics and our inquiry framework. Together with other sources of validity in the pilot testing, the results offered evidence to support the validity of MASIA.

    The aim of this study was to investigate the effects of "Environmental Chemistry" elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers' (SSSTs) self-perceptions of fluency with innovative technologies (InT) and scientific inquiry abilities. The study was conducted with 117 SSSTs (68 females and 49 males—aged 21-23 years) enrolled in the "Environmental Chemistry" elective course in spring semester of 2011-2012 academic year in a Turkish University. Within a simple (causal) experimental design, Innovative Technology Fluency Survey and the SSSTs' environmental research papers were employed to collect data. The results indicate that the "Environmental Chemistry" elective course via the TESI model improved the SSSTs' self-perceptions of fluency with InT and the scientific inquiry abilities. In light of the results, it is recommended that an undergraduate course for improving the SSSTs' higher-order scientific inquiry abilities and preparing academically papers should be devised and added into the science teacher-training programmes.

  2. An X-linked three allele model of hand preference and hand posture for writing.

    PubMed

    McKeever, Walter F

    2004-04-01

    This paper describes a genetic model of hand preferences for writing and for handwriting posture (HWP). The challenge of devising an X-linked model for these aspects of human handedness was posed by the results of a large family handedness study (McKeever, 2000) that showed evidence of such linkage. Because X-linkage for handedness has been widely regarded as untenable, the prospects for developing such a model were not initially encouraging, but ultimately a viable model did suggest itself. Family studies of handedness and leading theories of handedness are briefly described, as is some of the research on HWP motivated by the theory of Levy and Nagylaki (1972). It is argued that there is evidence that HWP reflects a biological dictate and not just individual "choices" or "adaptations" to writing in a left-to-right direction with the left hand. The model proposes that inverted handwriting posture is not necessarily highly related to speech and language lateralities of sinistrals, but that it reveals an interhemispheric mediation of writing. It is hypothesised that it reflects a specialisation of the left angular gyrus (with some possible extension into the supramarginal gyrus) for the storage of movement and timing sequences of cursive writing, and right hemisphere motor programming of the motor output of writing. It is also argued that no family handedness study conducted to date is adequate for testing the predictions of extant handedness theories, and the often wide variations between the results of family handedness studies are noted. It is suggested that fMRI studies could definitively test the HWP hypotheses of the model and that the hypothesis of X-linkage could be tested definitively should studies of the human genome identify a gene for handedness.

  4. Deaf, Hard-of-Hearing, and Hearing Signing Undergraduates' Attitudes toward Science in Inquiry-Based Biology Laboratory Classes.

    2017-01-01

    For science learning to be successful, students must develop attitudes toward support future engagement with challenging social issues related to science. This is especially important for increasing participation of students from underrepresented populations. This study investigated how participation in inquiry-based biology laboratory classes affected students' attitudes toward science, focusing on deaf, hard-of-hearing, and hearing signing students in bilingual learning environments (i.e., taught in American Sign Language and English). Analysis of reflection assignments and interviews revealed that the majority of students developed positive attitudes toward science and scientific attitudes after participating in inquiry-based biology laboratory classes. Attitudinal growth appears to be driven by student value of laboratory activities, repeated direct engagement with scientific inquiry, and peer collaboration. Students perceived that hands-on experimentation involving peer collaboration and a positive, welcoming learning environment were key features of inquiry-based laboratories, affording attitudinal growth. Students who did not perceive biology as useful for their majors, careers, or lives did not develop positive attitudes. Students highlighted the importance of the climate of the learning environment for encouraging student contribution and noted both the benefits and pitfalls of teamwork. Informed by students' characterizations of their learning experiences, recommendations are made for inquiry-based learning in college biology. © 2017 C. Gormally.

  7. Dose-response relation between exposure to two types of hand-arm vibration and sensorineural perception of vibration.

    1995-05-01

    31 railway workers and 32 lumberjacks were examined to compare the dose-response relation between the exposure to two types of hand-arm vibration and the sensory disturbances in peripheral nerves as evaluated by the vibration perception thresholds (VPTs). Clinical examinations were carried out that included measurements of the VPTs, and electroneuromyography (ENMG), and an inquiry to confirm the use of vibrating tools. Diseases of the central nervous system and neuropathies were checked by inquiry and a clinical examination, diabetes was excluded by a blood sample analysis, and the subjects with carpal tunnel syndrome confirmed with ENMG were excluded from the study. Lifetime use of hand held tamping machines (railway workers) and chain saws (lumberjacks) had a significant correlation with the VPTs at frequencies from 32 to 500 Hz. The increase of the VPTs (250 Hz) in relation to use of vibrating tools was 1.8-fold higher on average in the whole group and 2.3-fold higher in the young (< 45) railway workers who had used hand held tamping machines, than in the corresponding groups of lumberjacks, who had used chain saws, whereas the frequency weighted acceleration of vibration in tamping machines was fourfold. There was a significant dose-response relation between the exposure to hand-arm vibration and the VPTs. The VPTs as a function of the frequency weighted acceleration of vibration and the exposure to vibration gave promising results for assessment of the risk of damage to sensory nerves induced by vibration.

    2013-12-01

    When students collaboratively design and build artifacts that require relevant understanding and application of science, many aspects of scientific literacy are developed. Design-based inquiry (DBI) is one such pedagogy that can serve these desired goals of science education well. Focusing on a Projectile Science curriculum previously found to be implemented with satisfactory fidelity, we investigate the many hidden challenges when using DBI with Grade 8 students from one school in Singapore. A case study method was used to analyze video recordings of DBI lessons conducted over 10 weeks, project presentations, and interviews to ascertain the opportunities for developing scientific literacy among participants. One critical factor that hindered learning was task selection by teachers, which emphasized generic scientific process skills over more important cognitive and epistemic learning goals. Teachers and students were also jointly engaged in forms of inquiry that underscored artifact completion over deeper conceptual and epistemic understanding of science. Our research surfaced two other confounding factors that undermined the curriculum; unanticipated teacher effects and the underestimation of the complexity of DBI and of inquiry science in general. Thus, even though motivated or experienced teachers can implement an inquiry science curriculum with good fidelity and enjoy school-wide support, these by themselves will not guarantee deep learning of scientific literacy in DBI. Recommendations are made for navigating the hands- and minds-on aspects of learning science that is an asset as well as inherent danger during DBI teaching.

  12. Hebbian learning of hand-centred representations in a hierarchical neural network model of the primate visual system.

    PubMed

    Born, Jannis; Galeazzi, Juan M; Stringer, Simon M

    2017-01-01

    A subset of neurons in the posterior parietal and premotor areas of the primate brain respond to the locations of visual targets in a hand-centred frame of reference. Such hand-centred visual representations are thought to play an important role in visually-guided reaching to target locations in space. In this paper we show how a biologically plausible, Hebbian learning mechanism may account for the development of localized hand-centred representations in a hierarchical neural network model of the primate visual system, VisNet. The hand-centered neurons developed in the model use an invariance learning mechanism known as continuous transformation (CT) learning. In contrast to previous theoretical proposals for the development of hand-centered visual representations, CT learning does not need a memory trace of recent neuronal activity to be incorporated in the synaptic learning rule. Instead, CT learning relies solely on a Hebbian learning rule, which is able to exploit the spatial overlap that naturally occurs between successive images of a hand-object configuration as it is shifted across different retinal locations due to saccades. Our simulations show how individual neurons in the network model can learn to respond selectively to target objects in particular locations with respect to the hand, irrespective of where the hand-object configuration occurs on the retina. The response properties of these hand-centred neurons further generalise to localised receptive fields in the hand-centred space when tested on novel hand-object configurations that have not been explored during training. Indeed, even when the network is trained with target objects presented across a near continuum of locations around the hand during training, the model continues to develop hand-centred neurons with localised receptive fields in hand-centred space. With the help of principal component analysis, we provide the first theoretical framework that explains the behavior of Hebbian learning

    2016-11-01

    The power of music to resonate within us transcends conventional boundaries established in cultural, geographic, and political contexts. In our world, as physics educators, so does the resonating of physics phenomena. Secondary level physics is a perfect place to blend these two genres. While advocating for STEM-based education is at the forefront of pedagogical reform, seldom do we use this cross-boundary vision as the foundation to teach and learn in true collaboration of science and arts classrooms. As music enthusiasts, and physics educators, we developed new resources for a blended music and physics class through inquiry-based learning activities. Punctuated with modern technology, we aimed our activities for an engaging learning experience towards developing conceptual understandings of sound and harmonics at the grade 11 level. The umbrella activity shared here was designed to engage a wide range of students through the universal language of music, and provide them a hands-on and minds-on experience to explore harmonics through both music and physics lenses. It is our intention to provide readers with an overview of the activity, a description of exemplar student-designed inquiry-based investigations, and helpful suggestions for potential for use in reader’s classrooms.

  15. A theory of planned behaviour-based analysis of TIMSS 2011 to determine factors influencing inquiry teaching practices in high-performing countries

    2017-07-01

    Given the abundance of literature describing the strong relationship between inquiry-based teaching and student achievement, more should be known about the factors impacting science teachers' classroom inquiry implementation. This study utilises the theory of planned behaviour to propose and validate a causal model of inquiry-based teaching through analysing data relating to high-performing countries retrieved from the 2011 Trends in International Mathematics and Science Study assessments. Data analysis was completed through structural equation modelling using a polychoric correlation matrix for data input and diagonally weighted least squares estimation. Adequate fit of the full model to the empirical data was realised. The model demonstrates that the extent the teachers participated in academic collaborations was positively related to their occupational satisfaction, confidence in teaching inquiry, and classroom inquiry practices. Furthermore, the teachers' confidence with implementing inquiry was positively related to their classroom inquiry implementation and occupational satisfaction. However, perceived student-generated constraints demonstrated a negative relationship with the teachers' confidence with implementing inquiry and occupational satisfaction. Implications from this study include supporting teachers through promoting collaborative opportunities that facilitate inquiry-based practices and occupational satisfaction.

    We propose a model with the left-handed and right-handed continuous Abelian gauge symmetry; U(1) L × U(1) R . Then three right-handed neutrinos are naturally required to achieve U(1) R anomaly cancellations, while several mirror fermions are also needed to do U(1) L anomaly cancellations. Then we formulate the model, and discuss its testability of the new gauge interactions at collider physics such as the large hadron collider (LHC) and the international linear collider (ILC). In particular, we can investigate chiral structure of the interactions by the analysis of forward-backward asymmetry based on polarized beam at the ILC.

    Despite that BYOD (Bring Your Own Device) technology model has been increasingly adopted in education, few studies have been reported on how to integrate various apps on BYOD into inquiry-based pedagogical practices in primary schools. This article reports a case study, examining what apps on BYOD can help students enhance their science learning, and how students develop their science knowledge in a seamless inquiry-based learning environment supported by these apps. A variety of qualitative data were collected and analyzed. The findings show that the affordances of the apps on BYOD could help students improve their science knowledge without time and place constraints and gain a better sense of ownership in learning.

  15. Reinstating the 'Queen': understanding philosophical inquiry in nursing.

    PubMed

    Pesut, Barbara; Johnson, Joy

    2008-01-01

    This paper is an introduction to the characteristics of philosophical inquiry. Despite over a century of philosophical thinking in nursing, philosophical inquiry has yet to be positioned as contributing substantially to the field of nursing's inquiry. There is a need to articulate the nature and characteristics of philosophical inquiry for researchers new to this perspective. We begin by addressing a common question that surfaces when one begins a work that is philosophical in nature, how does one differentiate between nursing philosophy and nursing theory? We then address the nature and characteristics of philosophical inquiry. We conclude by considering the question of whether philosophical inquiry might be considered a form of qualitative inquiry. Unlike science, which relies upon investigative methods, philosophical inquiry relies upon the capacities to think and reason. Problems characteristic of philosophical inquiry include conceptual clarification, analysis of arguments and problems related to the ontology, epistemology and ethics of nursing. Although methodological approaches to philosophical inquiry are diverse, common tools include assumptions and the intellectual processes of conceptualizing, judging and reasoning within a context of wonder. Some have argued that to neglect philosophy in nursing is to place the discipline at risk. However, there is little guidance available to researchers new to this method of inquiry. By providing a beginning roadmap, our hope is that philosophical inquiry will take its place alongside scientific methods of inquiry with the goal of constructing robust knowledge for the discipline of nursing.

    Park, GiTae; Kim, Soowon

    2013-02-28

    A hand biometric authentication method based on measurements of the user's hand geometry and vascular pattern is proposed. To acquire the hand geometry, the thickness of the side view of the hand, the K-curvature with a hand-shaped chain code, the lengths and angles of the finger valleys, and the lengths and profiles of the fingers were used, and for the vascular pattern, the direction-based vascular-pattern extraction method was used, and thus, a new multimodal biometric approach is proposed. The proposed multimodal biometric system uses only one image to extract the feature points. This system can be configured for low-cost devices. Our multimodal biometric-approach hand-geometry (the side view of the hand and the back of hand) and vascular-pattern recognition method performs at the score level. The results of our study showed that the equal error rate of the proposed system was 0.06%.

    This study examined the impact of an inquiry-based instructional intervention on (a) children's ability to conduct science inquiry overall and to use specific skills in inquiry, and (b) narrowing the gaps in children's ability among demographic subgroups of students. The intervention consisted of instructional units, teacher workshops, and classroom practices. The study involved 25 third- and fourth-grade students from six elementary schools representing diverse linguistic and cultural groups. Quantitative results demonstrated that the intervention enhanced the inquiry ability of all students regardless of grade, achievement, gender, ethnicity, socioeconomic status (SES), home language, and English proficiency. Particularly, low-achieving, low-SES, and English for Speakers of Other Languages (ESOL) exited students made impressive gains. The study adds to the existing literature on designing learning environments that foster science inquiry of all elementary students.

    2017-09-01

    Voltaic Cell is a sub-concept of electrochemistry that is considered difficult to be comprehended by learners Voltaic Cell is a sub concept of electrochemistry that is considered difficult to be understood by learners so that impacts on student activity in learning process. Therefore the learning model Argument Based Science Inquiry (ABSI) will be applied to the concept of Voltaic cell. This research aims to describe students’ activities during learning process using ABSI model and to analyze students’ competency to solve ABSI-based worksheets (LK) of Voltaic Cell concept. The method used in this research was the “mix-method-quantitative-embedded” method with subjects of the study: 39 second-semester students of Chemistry Education study program. The student activity is quite good during ABSI learning. The students’ ability to complete worksheet (LK) for every average phase is good. In the phase of exploration of post instruction understanding, it is categorized very good, and in the phase of negotiation shape III: comparing science ideas to textbooks or other printed resources merely reach enough category. Thus, the ABSI learning has improved the student levels of activity and students’ competency to solve the ABSI-based worksheet (LK).

  10. The Effect of Serious Video Game Play on Science Inquiry Scores

    NASA Astrophysics Data System (ADS)

    Hilosky, Alexandra Borzillo

    American students are not developing the science inquiry skills needed to solve complex 21st century problems, thus impacting the workforce. In 2009, American high school students ranked 21 out of 26 in the category of problem-solving according to the Program for International Student Assessment. Serious video games have powerful epistemic value and are beneficial with respect to enhancing inquiry, effective problem-solving. The purpose of this correlational, quantitative study was to test Gee's assumption regarding the cycle of thinking (routinization, automatization, and deroutinization) by determining whether players status was a significant predictor of science inquiry scores, controlling for age, gender, and major. The 156 non-random volunteers who participated in this study were enrolled in a 2-year college in the northeastern U.S. Multiple regression analyses revealed that major was the strongest overall (significant) predictor, b = -.84, t(149) = -3.70, p < .001, even though gamer status served as a significant predictor variable for Stage 1 only, b = -.48, t(149) = -2.37, p = .019. Participants who reported playing serious video games scored .48 points higher than non-players of serious video games regardless of age, gender, and major, which supports previous studies that have found significant differences in scientific inquiry abilities related to forming hypotheses and identifying problems based on serious video game play. Recommendations include using serious games as instructional tools and to assess student learning (formative and summative), especially among non-traditional learners.

  15. Evidence of common and separate eye and hand accumulators underlying flexible eye-hand coordination

    PubMed Central

    Jana, Sumitash; Gopal, Atul

    2016-01-01

    Eye and hand movements are initiated by anatomically separate regions in the brain, and yet these movements can be flexibly coupled and decoupled, depending on the need. The computational architecture that enables this flexible coupling of independent effectors is not understood. Here, we studied the computational architecture that enables flexible eye-hand coordination using a drift diffusion framework, which predicts that the variability of the reaction time (RT) distribution scales with its mean. We show that a common stochastic accumulator to threshold, followed by a noisy effector-dependent delay, explains eye-hand RT distributions and their correlation in a visual search task that required decision-making, while an interactive eye and hand accumulator model did not. In contrast, in an eye-hand dual task, an interactive model better predicted the observed correlations and RT distributions than a common accumulator model. Notably, these two models could only be distinguished on the basis of the variability and not the means of the predicted RT distributions. Additionally, signatures of separate initiation signals were also observed in a small fraction of trials in the visual search task, implying that these distinct computational architectures were not a manifestation of the task design per se. Taken together, our results suggest two unique computational architectures for eye-hand coordination, with task context biasing the brain toward instantiating one of the two architectures. NEW & NOTEWORTHY Previous studies on eye-hand coordination have considered mainly the means of eye and hand reaction time (RT) distributions. Here, we leverage the approximately linear relationship between the mean and standard deviation of RT distributions, as predicted by the drift-diffusion model, to propose the existence of two distinct computational architectures underlying coordinated eye-hand movements. These architectures, for the first time, provide a computational basis for

  19. Hand Biometric Recognition Based on Fused Hand Geometry and Vascular Patterns

    PubMed Central

    Park, GiTae; Kim, Soowon

    2013-01-01

    A hand biometric authentication method based on measurements of the user's hand geometry and vascular pattern is proposed. To acquire the hand geometry, the thickness of the side view of the hand, the K-curvature with a hand-shaped chain code, the lengths and angles of the finger valleys, and the lengths and profiles of the fingers were used, and for the vascular pattern, the direction-based vascular-pattern extraction method was used, and thus, a new multimodal biometric approach is proposed. The proposed multimodal biometric system uses only one image to extract the feature points. This system can be configured for low-cost devices. Our multimodal biometric-approach hand-geometry (the side view of the hand and the back of hand) and vascular-pattern recognition method performs at the score level. The results of our study showed that the equal error rate of the proposed system was 0.06%. PMID:23449119

  2. The Teaching of Anthropogenic Climate Change and Earth Science via Technology-Enabled Inquiry Education

    NASA Technical Reports Server (NTRS)

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

    2016-01-01

    A gap has existed between the tools and processes of scientists working on anthropogenic global climate change (AGCC) and the technologies and curricula available to educators teaching the subject through student inquiry. Designing realistic scientific inquiry into AGCC poses a challenge because research on it relies on complex computer models, globally distributed data sets, and complex laboratory and data collection procedures. Here we examine efforts by the scientific community and educational researchers to design new curricula and technology that close this gap and impart robust AGCC and Earth Science understanding. We find technology-based teaching shows promise in promoting robust AGCC understandings if associated curricula address mitigating factors such as time constraints in incorporating technology and the need to support teachers implementing AGCC and Earth Science inquiry. We recommend the scientific community continue to collaborate with educational researchers to focus on developing those inquiry technologies and curricula that use realistic scientific processes from AGCC research and/or the methods for determining how human society should respond to global change.

  4. Effects of an Inquiry-Based Short Intervention on State Test Anxiety in Comparison to Alternative Coping Strategies

    PubMed Central

    Krispenz, Ann; Dickhäuser, Oliver

    2018-01-01

    Background and Objectives: Test anxiety can have undesirable consequences for learning and academic achievement. The control-value theory of achievement emotions assumes that test anxiety is experienced if a student appraises an achievement situation as important (value appraisal), but feels that the situation and its outcome are not fully under his or her control (control appraisal). Accordingly, modification of cognitive appraisals is assumed to reduce test anxiety. One method aiming at the modification of appraisals is inquiry-based stress reduction. In the present study (N = 162), we assessed the effects of an inquiry-based short intervention on test anxiety. Design: Short-term longitudinal, randomized control trial. Methods: Focusing on an individual worry thought, 53 university students received an inquiry-based short intervention. Control participants reflected on their worry thought (n = 55) or were distracted (n = 52). Thought related test anxiety was assessed before, immediately after, and 2 days after the experimental treatment. Results: After the intervention as well as 2 days later, individuals who had received the inquiry-based intervention demonstrated significantly lower test anxiety than participants from the pooled control groups. Further analyses showed that the inquiry-based short intervention was more effective than reflecting on a worry thought but had no advantage over distraction. Conclusions: Our findings provide first experimental evidence for the effectiveness of an inquiry-based short intervention in reducing students’ test anxiety. PMID:29515507

    Vass, Laszlo

    The purpose of this quantitative, quasi-experimental study was to measure the effect of a student-centered instructional method called guided inquiry on the achievement of students in a unit of study in high school biology. The study used a non-random sample of 109 students, the control group of 55 students enrolled in high school one, received teacher centered instruction while the experimental group of 54 students enrolled at high school two received student-centered, guided inquiry instruction. The pretest-posttest design of the study analyzed scores using an independent t-test, a dependent t-test (p = <.001), an ANCOVA (p = .007), mixed method ANOVA (p = .024) and hierarchical linear regression (p = <.001). The experimental group that received guided inquiry instruction had statistically significantly higher achievement than the control group.

    2017-11-01

    Understanding of science instructional leading to the formation of student scientific literacy, seems not yet fully understood well by science teachers. Because of this, certainly needs to be reformed because science literacy is a major goal in science education for science education reform. Efforts of development science literacy can be done by help students develop an information conception of the Nature of Science (NoS) and apply inquiry approach. It is expected that students’ science literacy can develop more optimal by combining NoS within inquiry approach. The purpose of this research is to produce scientific literacy development model of NoS within inquiry-based learning. The preparation of learning tools will be maked through Research and Development (R & D) following the 4-D model (Define, Design, Develop, and Disseminate) and Borg & Gall. This study is a follow-up of preliminary research results about the inquiry profile of junior high school students indicating that most categories are quite good. The design of the model NoS within inquiry approach for developing scientific literacy is using MER Model in development educational reconstruction. This research will still proceed to the next stage that is Develop.

  7. Hand skin reconstruction from skeletal landmarks.

    2007-11-01

    Many studies related to three-dimensional facial reconstruction have been previously reported. On the other hand, no extensive work has been found in the literature about hand reconstruction as an identification method. In this paper, the feasibility of virtual reconstruction of hand skin based on (1) its skeleton and (2) another hand skin and skeleton used as template was assessed. One cadaver hand and one volunteer's hand have been used. For the two hands, computer models of the bones and skin were obtained from computerized tomography. A customized software allowed locating spatial coordinates of bony anatomical landmarks on the models. From these landmarks, the spatial relationships between the models were determined and used to interpolate the missing hand skin. The volume of the interpolated skin was compared to the real skin obtained from medical imaging for validation. Results seem to indicate that such a method is of interest to give forensic investigators morphological clues related to an individual hand skin based on its skeleton. Further work is in progress to finalize the method.

    2005-12-01

    The Enduring Resources for Earth Science Education (ERESE) project has now held two professional development workshops to teach and apply the five stage inquiry lesson model for teaching plate tectonics. This development based on a collaborative effort between earth scientists, educators, librarians, and data archive managers, and works towards a classroom practice that focuses on transferring ownership of a classroom inquiry to the learner. The ERESE inquiry model features a modular, five stage approach: (1) a thoughtful orientation to create an environment of physical and intellectual safety for the learner, (2) a carefully chosen provocative phenomenon used to allow the learner to develop a wide range of scientific questions (3) a debriefing that reviews and honors the learners' questions along with the development of a testable hypothesis, (4) learners consult with ERESE resource matrices and the internet to obtain data and other information to test the hypothesis, and (5) the learners present their results in a presentation. The process of ERESE inquiry lessons is guided by a master template and involves a detailed teachers log for documentation of all activities. All products of the process are archived. The master template and teachers log are designed in a modular fashion that ultimately will accommodate a wide range of inquiry lesson styles and the variety of resources available to support the process. Key ERESE modules include: (1) a master template that provides a framework for lesson development, (2) provocative phenomenon for question generation and hypothesis development by the learner, (3) the ERESE resource matrix (which archives text, images and data by expert level for a wide range of scientific questions), and (4) a reflective essay that monitors the ownership transfer to the learner. Modular design of ERESE products allows for the archival of specific types of materials that can be independently accessed and applied to different inquiry styles

  12. Experience and Reflection: Preservice Science Teachers' Capacity for Teaching Inquiry

    NASA Astrophysics Data System (ADS)

    Melville, Wayne; Fazio, Xavier; Bartley, Anthony; Jones, Doug

    2008-10-01

    In this article, we investigate the relationship between preservice teachers’ inquiry experience and their capacity to reflect on the challenges involved in implementing inquiry into classrooms. For data, we draw on the personal narratives of preservice science teachers enrolled in science instruction courses. Preservice teachers with extensive inquiry experiences perceive implementation challenges principally in terms of teaching and student learning. This contrasts with the perceptions of preservice teachers with limited inquiry experience for whom the main concerns relate to the negative perceptions of others, time, the curriculum, and materials. By identifying these perceptions, it may be possible to develop courses that assist limited and moderate-experience preservice teachers’ move toward the perceptions of their more inquiry experienced colleagues.

    2007-12-01

    Using Power-Point technology and hands-on materials, a 45 minute lesson has been created to allow students to explore the cause of lunar phases. Students work in cooperative pairs to model the different phases of the moon. In addition, this lesson does not require a bright light source. Using a partially painted Styrofoam ball, a small cup of Play-dough, a simple, protractor, and a data collection sheet, students observe the lunar phases and measure the angle between the sun and the moon. Students place the moon model in eight different positions simulating its orbit around the earth and record the observed changes. The Power-Point presentation contains three segments. The first section allows the teacher to determine the students’ level of prior knowledge about the moon and to uncover possible misconceptions. The second section facilitates the students’ learning by displaying the proper alignment of the model and the proper viewing position for the students. Finally, the presentation culminates in a review of what the students have just observed. This lesson has been created to meet Georgia Performance Standards (GPS) for 4th grade science regarding the cause of lunar phases. Teacher and student responses to this lesson have been extremely positive.

    NASA Astrophysics Data System (ADS)

    Affhalter, Maria Geralyn

    An action research project using science inquiry labs and cooperative learning groups examined the effects of same-gender and co-educational classrooms on science achievement and teacher-assigned or self-selected group roles on students' role preferences. Fifty-nine seventh grade students from a small rural school district participated in two inquiry labs in co-educational classrooms or in an all-female classroom, as determined by parents at the beginning of the academic year. Students were assigned to the same cooperative groups for the duration of the study. Pretests and posttests were administered for each inquiry-based science lab. Posttest assessments included questions for student reflection on role assignment and role preference. Instruction did not vary and a female science teacher taught all class sections. The same-gender classroom and co-ed classrooms produced similar science achievement scores on posttests. Students' cooperative group roles, whether teacher-assigned or self-selected, produced similar science achievement scores on posttests. Male and female students shared equally in favorable and unfavorable reactions to their group roles during the science inquiry labs. Reflections on the selection of the leader role revealed a need for females in co-ed groups to be "in charge". When reflecting on her favorite role of leader, one female student in a co-ed group stated, "I like to have people actually listen to me".

  16. Dose-response relation between exposure to two types of hand-arm vibration and sensorineural perception of vibration.

    Virokannas, H

    1995-01-01

    OBJECTIVES--31 railway workers and 32 lumberjacks were examined to compare the dose-response relation between the exposure to two types of hand-arm vibration and the sensory disturbances in peripheral nerves as evaluated by the vibration perception thresholds (VPTs). METHODS--Clinical examinations were carried out that included measurements of the VPTs, and electroneuromyography (ENMG), and an inquiry to confirm the use of vibrating tools. Diseases of the central nervous system and neuropathies were checked by inquiry and a clinical examination, diabetes was excluded by a blood sample analysis, and the subjects with carpal tunnel syndrome confirmed with ENMG were excluded from the study. RESULTS--Lifetime use of hand held tamping machines (railway workers) and chain saws (lumberjacks) had a significant correlation with the VPTs at frequencies from 32 to 500 Hz. The increase of the VPTs (250 Hz) in relation to use of vibrating tools was 1.8-fold higher on average in the whole group and 2.3-fold higher in the young (< 45) railway workers who had used hand held tamping machines, than in the corresponding groups of lumberjacks, who had used chain saws, whereas the frequency weighted acceleration of vibration in tamping machines was fourfold. CONCLUSION--There was a significant dose-response relation between the exposure to hand-arm vibration and the VPTs. The VPTs as a function of the frequency weighted acceleration of vibration and the exposure to vibration gave promising results for assessment of the risk of damage to sensory nerves induced by vibration.

  18. Scientists' conceptions of scientific inquiry: Revealing a private side of science

    NASA Astrophysics Data System (ADS)

    Reiff, Rebecca R.

    Science educators, philosophers, and pre-service teachers have contributed to conceptualizing inquiry but missing from the inquiry forum is an in-depth research study concerning science faculty conceptions of scientific inquiry. The science education literature has tended to focus on certain aspects of doing, teaching, and understanding scientific inquiry without linking these concepts. As a result, conceptions of scientific inquiry have been disjointed and are seemingly unrelated. Furthermore, confusion surrounding the meaning of inquiry has been identified as a reason teachers are not using inquiry in instruction (Welch et al., 1981). Part of the confusion surrounding scientific inquiry is it has been defined differently depending on the context (Colburn, 2000; Lederman, 1998; Shymansky & Yore, 1980; Wilson & Koran, 1976). This lack of a common conception of scientific inquiry is the reason for the timely nature of this research. The result of scientific journeys is not to arrive at a stopping point or the final destination, but to refuel with questions to drive the pursuit of knowledge. A three-member research team conducted Interviews with science faculty members using a semi-structured interview protocol designed to probe the subject's conceptions of scientific inquiry. The participants represented a total of 52 science faculty members from nine science departments (anthropology, biology, chemistry, geology, geography, school of health, physical education and recreation (HPER), medical sciences, physics, and school of environmental science) at a large mid-western research university. The method of analysis used by the team was grounded theory (Strauss & Corbin, 1990; Glaser & Strauss, 1967), in which case the frequency of concepts, patterns, and themes were coded to categorize scientists' conceptions of scientific inquiry. The results from this study address the following components: understanding and doing scientific inquiry, attributes of scientists engaged

    Treatment of skin with chlorine generates 'chlorine covers' which, in a previous study, exerted significant sustained bactericidal effects against transient skin flora on the upper arm and forearm. In this investigation, this effect was studied on both the transient and resident flora of the hands using test models for the evaluation of hand disinfectants as agreed upon in Austria and Germany. Chlorine covers were generated by bathing hands in a solution of 2% sodium tosylchloramide for 1 min. Subsequently, this cover was destroyed on one, randomly selected, hand by bathing it in a solution of 0.5% sodium thiosulphate for 15 s. The amount of chlorine on the fingertips of chlorinated hands was 2.2 +/- 0.4 micrograms/cm2; that on subsequently dechlorinated hands was 0.2 +/- 0.1 microgram/cm2. In experiments with artificially contaminated hands (Escherichia coli), the kinetics of bacterial die-off were the same on both hands. Also, in experiments with resident flora, the kinetics of bacterial die-off did not suggest bacterial reductions that increase with the duration of contact with the chlorine cover. It was concluded that with the test models used, a significant sustained antimicrobial effect of the chlorine cover could not be demonstrated on hands.

    Domjan, Heather Nicole

    The purpose of this study is to describe elementary school teachers' perceptions of science as inquiry in science instruction. A descriptive survey research design was used to collect data regarding elementary science teachers' knowledge and beliefs related to inquiry and its role in science education. The written section of the survey was analyzed and interpreted descriptively through phenomenological data and the constant comparative method (Glaser & Strauss, 1967; Lincoln & Guba, 1985). The researcher used the constant comparative method to identify statements, perceptions, and impressions that occurred over time during the study (Janesick, 1994). Ninety-two elementary school teachers who teach science in a large suburban district southwest of Houston, Texas were administered a three part Understanding Science as Inquiry Survey (USAI) developed by the researcher. Participants communicated in writing personal definitions of inquiry in elementary science as well as determined to what extent inquiry was used in four elementary science classroom scenarios. The survey items were based on the following four components of inquiry described by Inquiry and the National Science Education Standards (2000): (1) conceptual knowledge, (2) process skills, (3) nature of science, and (4) affect. The study describes elementary school teachers' perceptions about science as inquiry. Conclusions for Part A of the USAI Survey indicate that participants define inquiry as: mostly process skills, some conceptual knowledge, and very little affect with no perception of the nature of science. The Likert scale ratings for the scenarios in Part B of the USAI Survey reveal that participants have varied perceptions regarding teaching science as inquiry. The written section of Part B reveals participants' perceptions to be similar to that of their Likert scale ratings except in scenario one. The researcher concludes that the participants in this study appear to have an incomplete understanding

  2. Using articulation and inscription as catalysts for reflection: Design principles for reflective inquiry

    2003-07-01

    The demand for students to engage in complex student-driven and information-rich inquiry investigations poses challenges to existing learning environments. Students are not familiar with this style of work, and lack the skills, tools, and expectations it demands, often forging blindly forward in the investigation. If students are to be successful, they need to learn to be reflective inquirers, periodically stepping back from an investigation to evaluate their work. The fundamental goal of my dissertation is to understand how to design learning environments to promote and support reflective inquiry. I have three basic research questions: how to define this mode of work, how to help students learn it, and understanding how it facilitates reflection when enacted in a classroom. I take an exploratory approach in which, through iterative cycles of design, development, and reflection, I develop principles of design for reflective inquiry, instantiate those principles in the design of a software environment, and test that software in the context of classroom work. My work contributes to the understanding of reflective inquiry in three ways: First, I define a task model that describes the kinds of operations (cognitive tasks) that students should engage in as reflective inquirers. These operations are defined in terms of two basic tasks: articulation and inscription, which serve as catalysts for externalizing student thinking as objects of and triggers for reflection. Second, I instantiate the task model in the design of software tools (the Progress Portfolio). And, through proof of concept pilot studies, I examine how the task model and tools helped students with their investigative classroom work. Finally, I take a step back from these implementations and articulate general design principles for reflective inquiry with the goal of informing the design of other reflective inquiry learning environments. There are three design principles: (1) Provide a designated work space

    The problem. Recent reform efforts in science education have culminated in National Science Education Standards (NSES), which include the theme of inquiry across all grade levels. Consideration must be given to teachers' conceptions of inquiry, and their perceived roles, as they implement the processes of inquiry in the science classroom. Because of the change in pedagogy required by the standards, research efforts must address these areas. Research questions. The following research questions guided this study. (1) What are teachers' conceptions of inquiry? (2) What do the teachers consider important aspects of their roles when providing inquiry experiences for their students? (3) What do the teachers consider important aspects of the students' roles as inquirers? Research paradigm and methodology. The research paradigm that grounded this investigation is the constructivist paradigm proposed by Guba and Lincoln (1989). Participants were three elementary school teachers participating in the Elementary School Education Partners project. Qualitative methodology techniques used in the study included focus group discussion, semi-structured interviews, classroom observation with videotaping, teacher reflections, and fieldnotes. Data were analyzed using the constant comparative method as provided by Glaser and Strauss (1967). A case study format was used to discuss the results of themes that emerged. Results. Themes that emerged from the data were (a) inquiry is viewed as a teaching strategy; (b) the teachers' perceptions of the nature of inquiry are different from one another's; (c) there are differences in the degree of fit with the NSES description of inquiry; (d) the manner in which they see themselves as facilitators originates in their own educational experiences and varies from that of a guide, to a monitor, to one who models; and (e) teachers see the role of students as active participants in their learning but the teachers' perceptions of students' roles, as

  8. Inquiry-Based Instruction and High Stakes Testing

    NASA Astrophysics Data System (ADS)

    Cothern, Rebecca L.

    Science education is a key to economic success for a country in terms of promoting advances in national industry and technology and maximizing competitive advantage in a global marketplace. The December 2010 Program for International Student Assessment (PISA) ranked the United States 23rd of 65 countries in science. That dismal standing in science proficiency impedes the ability of American school graduates to compete in the global market place. Furthermore, the implementation of high stakes testing in science mandated by the 2007 No Child Left Behind (NCLB) Act has created an additional need for educators to find effective science pedagogy. Research has shown that inquiry-based science instruction is one of the predominant science instructional methods. Inquiry-based instruction is a multifaceted teaching method with its theoretical foundation in constructivism. A correlational survey research design was used to determine the relationship between levels of inquiry-based science instruction and student performance on a standardized state science test. A self-report survey, using a Likert-type scale, was completed by 26 fifth grade teachers. Participants' responses were analyzed and grouped as high, medium, or low level inquiry instruction. The unit of analysis for the achievement variable was the student scale score average from the state science test. Spearman's Rho correlation data showed a positive relationship between the level of inquiry-based instruction and student achievement on the state assessment. The findings can assist teachers and administrators by providing additional research on the benefits of the inquiry-based instructional method. Implications for positive social change include increases in student proficiency and decision-making skills related to science policy issues which can help make them more competitive in the global marketplace.

  9. The influence of democratic racism in nursing inquiry.

    Hilario, Carla T; Browne, Annette J; McFadden, Alysha

    2018-01-01

    Neoliberal ideology and exclusionary policies based on racialized identities characterize the current contexts in North America and Western Europe. Nursing knowledge cannot be abstracted from social, political and historical contexts; the task of examining the influence of race and racial ideologies on disciplinary knowledge and inquiry therefore remains an important task. Contemporary analyses of the role and responsibility of the discipline in addressing race-based health and social inequities as a focus of nursing inquiry remain underdeveloped. In this article, we examine nursing's engagement with ideas about race and racism and explore the ways in which nursing knowledge and inquiry have been influenced by race-based ideological discourses. Drawing on Henry and Tator's framework of democratic racism, we consider how strategic discursive responses-the discourses of individualism, multiculturalism, colour-blindness, political correctness and denial-have been deployed within nursing knowledge and inquiry to reinforce the belief in an essentially fair and just society while avoiding the need to acknowledge the persistence of racist discourses and ideologies. Greater theoretical, conceptual and methodological clarity regarding race, racialization and related concepts in nursing inquiry is needed to address health and social inequities. © 2017 John Wiley & Sons Ltd.

  10. Grasping with the eyes of your hands: hapsis and vision modulate hand preference.

    PubMed

    Stone, Kayla D; Gonzalez, Claudia L R

    2014-02-01

    Right-hand preference has been demonstrated for visually guided reaching and grasping. Grasping, however, requires the integration of both visual and haptic cues. To what extent does vision influence hand preference for grasping? Is there a hand preference for haptically guided grasping? Two experiments were designed to address these questions. In Experiment 1, individuals were tested in a reaching-to-grasp task with vision (sighted condition) and with hapsis (blindfolded condition). Participants were asked to put together 3D models using building blocks scattered on a tabletop. The models were simple, composed of ten blocks of three different shapes. Starting condition (Vision-First or Hapsis-First) was counterbalanced among participants. Right-hand preference was greater in visually guided grasping but only in the Vision-First group. Participants who initially built the models while blindfolded (Hapsis-First group) used their right hand significantly less for the visually guided portion of the task. To investigate whether grasping using hapsis modifies subsequent hand preference, participants received an additional haptic experience in a follow-up experiment. While blindfolded, participants manipulated the blocks in a container for 5 min prior to the task. This additional experience did not affect right-hand use on visually guided grasping but had a robust effect on haptically guided grasping. Together, the results demonstrate first that hand preference for grasping is influenced by both vision and hapsis, and second, they highlight how flexible this preference could be when modulated by hapsis.

    Scientific inquiry is widely accepted as a method of science teaching. Understanding its characteristics, called Nature of Scientific Inquiry (NOSI), is also necessary for a whole conception of scientific inquiry. In this study NOSI aspects were taught explicitly through student inquiries in nature in two summer science camps. Students conducted four inquiries through their questions about surrounding soil, water, plants, and animals under the guidance of university science educators. At the end of each investigation, students presented their inquiry. NOSI aspects were made explicit by one of the science educators in the context of the investigations. Effectiveness of the science camp program and its retention were determined by applying Views of Scientific Inquiry (VOSI-S) (Schwartz et al. 2008) questionnaire as pre-, post-, and retention test after two months. The patterns in the data were similar. The science camp program was effective in developing three of six NOSI aspects which were questions guide scientific research, multiple methods of research, and difference between data and evidence. Students' learning of these aspects was retained. Discussion about these and the other three aspects is included in the paper. Implications of differences between school and out-of-school science experiences are also discussed.

    2011-01-01

    This study compared the effectiveness of collaborative group composition and instructional method on reasoning gains and achievement in college biology. Based on initial student reasoning ability (i.e., low, medium, or high), students were assigned to either homogeneous or heterogeneous collaborative groups within either inquiry or didactic instruction. Achievement and reasoning gains were assessed at the end of the semester. Inquiry instruction, as a whole, led to significantly greater gains in reasoning ability and achievement. Inquiry instruction also led to greater confidence and more positive attitudes toward collaboration. Low-reasoning students made significantly greater reasoning gains within inquiry instruction when grouped with other low reasoners than when grouped with either medium or high reasoners. Results are consistent with equilibration theory, supporting the idea that students benefit from the opportunity for self-regulation without the guidance or direction of a more capable peer.

    This paper reports the integration of a kinematic model of the human hand during cylindrical grasping, with specific focus on the accurate mapping of thumb movement during grasping motions, and a novel, multi-degree-of-freedom assistive exoskeleton mechanism based on this model. The model includes thumb maximum hyper-extension for grasping large objects (~> 50 mm). The exoskeleton includes a novel four-bar mechanism designed to reproduce natural thumb opposition and a novel synchro-motion pulley mechanism for coordinated finger motion. A computer aided design environment is used to allow the exoskeleton to be rapidly customized to the hand dimensions of a specific patient. Trials comparing the kinematic model to observed data of hand movement show the model to be capable of mapping thumb and finger joint flexion angles during grasping motions. Simulations show the exoskeleton to be capable of reproducing the complex motion of the thumb to oppose the fingers during cylindrical and pinch grip motions. © 2011 IEEE

    The University of South Florida, College of Marine Science Oceans: GK-12 Teaching Fellowship Program is successfully enriching science learning via the oceans. Funded by the National Science Foundation, the program provides a unique opportunity among scientists and K-12 teachers to interact with the intention of bringing ocean science concepts and research to the classroom environment enhance the experience of learning and doing science, and to promote `citizen scientists' for the 21st century. The success of the program relies heavily on the extensive summer training program where graduate students develop teaching skills, create inquiry based science activities for a summer Oceanography Camp for Girls program and build a relationship with their mentor teacher. For the last year and a half, two graduate students from the College of Marine Science have worked in cooperation with teachers from the Pinellas county School District, Southside Fundamental Middle School. Successful lesson plans brought into a 6th grade Earth Science classroom include Weather and climate: Global warming, The Geologic timescale: It's all about time, Density: Layering liquids, and Erosion processes: What moves water and sediment. The school and students have benefited greatly from the program experiencing hands-on inquiry based science and the establishment of an after school science club providing opportunities for students to work on their science fair projects and pursuit other science interests. Students are provided scoring rubrics and their progress is creatively assessed through KWL worksheets, concept maps, surveys, oral one on one and classroom discussions and writing samples. The year culminated with a series of hands on lessons at the nearby beach, where students demonstrated their mastery of skills through practical application. Benefits to the graduate student include improved communication of current science research to a diverse audience, a better understanding of the

    Objectives This article reviews an evaluation vector model driven from a participatory action research leveraging a collective inquiry system named SMILE (Stanford Mobile Inquiry-based Learning Environment). Methods SMILE has been implemented in a diverse set of collective inquiry generation and analysis scenarios including community health care-specific professional development sessions and community-based participatory action research projects. In each scenario, participants are given opportunities to construct inquiries around physical and emotional health-related phenomena in their own community. Results Participants formulated inquiries as well as potential clinical treatments and hypothetical scenarios to address health concerns or clarify misunderstandings or misdiagnoses often found in their community practices. From medical universities to rural village health promotion organizations, all participatory inquiries and potential solutions can be collected and analyzed. The inquiry and solution sets represent an evaluation vector which helps educators better understand community health issues at a much deeper level. Conclusions SMILE helps collect problems that are most important and central to their community health concerns. The evaluation vector, consisting participatory and collective inquiries and potential solutions, helps the researchers assess the participants' level of understanding on issues around health concerns and practices while helping the community adequately formulate follow-up action plans. The method used in SMILE requires much further enhancement with machine learning and advanced data visualization. PMID:27525157

This research provided evidence that hypothesis testing can support the integrated acquisition of conceptual and procedural knowledge in science. Participants' conceptual elaborations of Mendelian inheritance were enhanced. There were qualitative changes in the nature of the participants' explanations. Moreover, the average percentage of correct responses improved from 39% on the pretest to 67% on the posttest. Findings also suggest those prospective science teachers' experiences as learners of science in their methods course served as a powerful tool for thinking about the role of inquiry in teaching and learning science. They had mixed views about enacting inquiry in their teaching in the future. All of them stated some kind of general willingness to do so; yet, they also mentioned some reservations and practical considerations about inquiry-based teaching.

  4. Effects of Web based inquiry on physical science teachers and students in an urban school district

    NASA Astrophysics Data System (ADS)

    Stephens, Joanne

    An inquiry approach in teaching science has been advocated by many science educators for the past few decades. Due to insufficient district funding for science teaching, inadequate science laboratory facilities, and outdated science materials, inquiry teaching has been difficult for many science teachers, particularly science teachers in urban settings. However, research shows that the availability of computers with high speed Internet access has increased in all school districts. This study focused on the effects of inservice training on teachers and using web based science inquiry activities with ninth grade physical science students. Participants were 16 science teachers and 474 physical science students in an urban school district of a large southern U.S. city. Students were divided into control and experimental groups. The students in the experimental group participated in web based inquiry activities. Students in the control group were taught using similar methods, but not web based science activities. Qualitative and quantitative data were collected over a nine-week period using instruments and focus group interviews of students' and teachers' perceptions of the classroom learning environment, students' achievement, lesson design and classroom implementation, science content of lesson, and classroom culture. The findings reported that there were no significant differences in teachers' perception of the learning environment before and after implementing web based inquiry activities. The findings also reported that there were no overall significant differences in students' perceptions of the learning environment and achievement, pre-survey to post-survey, pre-test to post-test, between the control group and experimental group. Additional findings disclosed that students in the experimental group learned in a collaborative environment. The students confirmed that collaborating with others contributed to a deeper understanding of the science content. This study

    BACKGROUND: The objective of the present study was to evaluate the effect of the two methods of delivery, “hands-on” vs. “hands poised”, on perineal trauma and delivery outcome in primiparous women referred to Shariati Hospital of Isfahan during 2007-2008. METHODS: In a clinical trial study, 100 low risk primiparous pregnant women were randomly assigned to two hands-on and hand-poised (hands-off) groups. In the hands-on group, this method was used to control fetal head in the second stage of labor. It means that the fingers of one hand supported fetal occiput and the other hand applied slight pressure on the head to control the delivery of the head during the crowning process. In the hands-poised group, midwife observed the parturient woman and do not touch perineum during the second labor stage while fetal head was delivering. Then, the two groups were compared in terms of perineal trauma, as well as neonatal and delivery outcome. RESULTS: Demographic characteristics of all studied women were similar in two groups. The rate of episiotomy was higher in hands-on group (84% vs. 40%, p = 0.001). The rate of postpartum hemorrhage (4th stage) was higher in hands-on group (12% vs. 4%, p = 0.04). The rate of mild and moderate postpartum pain in hands-on group was higher than hands-off group (70% vs. 58% and 29% vs. 10%, p < 0.001) but sever pain was not different in two groups. CONCLUSIONS: It seems that hands-poised method is associated with less perineal trauma, particularly regarding the lower need for episiotomy and postpartum hemorrhage. PMID:22279480
