Student-Generated Scientific Inquiry for Elementary Education Undergraduates: Course Development, Outcomes and Implications

ERIC Educational Resources Information Center

Salter, Irene; Atkins, Leslie

2013-01-01

While some researchers have argued for science classrooms that embrace open-inquiry by engaging students in doing science as scientists do (cf. National Research Council [NRC] 1996; Driver et al. in "Sci Educ" 84:287-312, 2000; Windschitl et al. in "Sci Educ" 87(1):112-143, 2008), others have argued that open-inquiry is impractical, ineffective,…

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

2006-05-01

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

Impact of problem finding on the quality of authentic open inquiry science research projects

NASA Astrophysics Data System (ADS)

Labanca, Frank

2008-11-01

Problem finding is a creative process whereby individuals develop original ideas for study. Secondary science students who successfully participate in authentic, novel, open inquiry studies must engage in problem finding to determine viable and suitable topics. This study examined problem finding strategies employed by students who successfully completed and presented the results of their open inquiry research at the 2007 Connecticut Science Fair and the 2007 International Science and Engineering Fair. A multicase qualitative study was framed through the lenses of creativity, inquiry strategies, and situated cognition learning theory. Data were triangulated by methods (interviews, document analysis, surveys) and sources (students, teachers, mentors, fair directors, documents). The data demonstrated that the quality of student projects was directly impacted by the quality of their problem finding. Effective problem finding was a result of students using resources from previous, specialized experiences. They had a positive self-concept and a temperament for both the creative and logical perspectives of science research. Successful problem finding was derived from an idiosyncratic, nonlinear, and flexible use and understanding of inquiry. Finally, problem finding was influenced and assisted by the community of practicing scientists, with whom the students had an exceptional ability to communicate effectively. As a result, there appears to be a juxtaposition of creative and logical/analytical thought for open inquiry that may not be present in other forms of inquiry. Instructional strategies are suggested for teachers of science research students to improve the quality of problem finding for their students and their subsequent research projects.

Impact of Including Authentic Inquiry Experiences in Methods Courses for Pre-Service Secondary Teachers

NASA Astrophysics Data System (ADS)

Slater, T. F.; Elfring, L.; Novodvorsky, I.; Talanquer, V.; Quintenz, J.

2007-12-01

Science education reform documents universally call for students to have authentic and meaningful experiences using real data in the context of their science education. The underlying philosophical position is that students analyzing data can have experiences that mimic actual research. In short, research experiences that reflect the scientific spirit of inquiry potentially can: prepare students to address real world complex problems; develop students' ability to use scientific methods; prepare students to critically evaluate the validity of data or evidence and of the consequent interpretations or conclusions; teach quantitative skills, technical methods, and scientific concepts; increase verbal, written, and graphical communication skills; and train students in the values and ethics of working with scientific data. However, it is unclear what the broader pre-service teacher preparation community is doing in preparing future teachers to promote, manage, and successful facilitate their own students in conducting authentic scientific inquiry. Surveys of undergraduates in secondary science education programs suggests that students have had almost no experiences themselves in conducting open scientific inquiry where they develop researchable questions, design strategies to pursue evidence, and communicate data-based conclusions. In response, the College of Science Teacher Preparation Program at the University of Arizona requires all students enrolled in its various science teaching methods courses to complete an open inquiry research project and defend their findings at a specially designed inquiry science mini-conference at the end of the term. End-of-term surveys show that students enjoy their research experience and believe that this experience enhances their ability to facilitate their own future students in conducting open inquiry.

Long term stability of learning outcomes in undergraduates after an open-inquiry instruction on thermal science

NASA Astrophysics Data System (ADS)

Persano Adorno, Dominique; Pizzolato, Nicola; Fazio, Claudio

2018-02-01

This paper investigates the efficacy of an open-inquiry approach to achieve a long term stability of physics instruction. This study represents the natural continuation of a research project started four years ago when a sample of thirty engineering undergraduates, having already attended traditional university physics instruction, were involved in a six-week long learning experience of open-inquiry research activities within the highly motivating context of developing a thermodynamically efficient space base on Mars. Four years later, we explore the effectiveness of that learning experience by analyzing the outcomes that the students achieved by answering again the same questionnaire that was administered them both prior to and immediately after those activities. As we did in the first work, students' answers were classified within three epistemological profiles. Now, a comparison among students' outcomes during the three phases, namely, preinstruction, postinstruction, and after four years has been carried out. Immediately after the open-inquiry experience, the students obtained significant benefits in terms of the strengthening of their practical and reasoning abilities, by proficiently applying the learned concepts to face and solve real-world problem situations. In this study, the students' answers do not highlight any significant regress towards their preinstruction profiles. The global robustness of the teaching strategy adopted four years ago is confirmed by a statistically significant comparison with a control group of students who experienced the same curricular instruction except for the open inquiry-based workshop. Nevertheless, some changes have been observed and discussed in the light of the answers the students provided to a short interview regarding their studying or working experiences across the four-year temporal window.

Elucidating the electron transport in semiconductors via Monte Carlo simulations: an inquiry-driven learning path for engineering undergraduates

NASA Astrophysics Data System (ADS)

Persano Adorno, Dominique; Pizzolato, Nicola; Fazio, Claudio

2015-09-01

Within the context of higher education for science or engineering undergraduates, we present an inquiry-driven learning path aimed at developing a more meaningful conceptual understanding of the electron dynamics in semiconductors in the presence of applied electric fields. The electron transport in a nondegenerate n-type indium phosphide bulk semiconductor is modelled using a multivalley Monte Carlo approach. The main characteristics of the electron dynamics are explored under different values of the driving electric field, lattice temperature and impurity density. Simulation results are presented by following a question-driven path of exploration, starting from the validation of the model and moving up to reasoned inquiries about the observed characteristics of electron dynamics. Our inquiry-driven learning path, based on numerical simulations, represents a viable example of how to integrate a traditional lecture-based teaching approach with effective learning strategies, providing science or engineering undergraduates with practical opportunities to enhance their comprehension of the physics governing the electron dynamics in semiconductors. Finally, we present a general discussion about the advantages and disadvantages of using an inquiry-based teaching approach within a learning environment based on semiconductor simulations.

Physical Therapists' Perceptions of School-Based Practices.

PubMed

Holt, Sheryl L; Kuperstein, Janice; Effgen, Susan K

2015-01-01

Surveys have reported that most school-based physical therapists perceive ideal practices are not commonly implemented in their settings. Our aim was to obtain a more in-depth understanding of these perceptions through open-ended inquiry. Qualitative data were derived from voluntary open-ended responses provided upon completion of a survey regarding school-based physical therapy practice. Of the survey's 561 participants, 250 provided open-ended commentaries that were analyzed using interpretive phenomenology. Six qualitative themes emerged from the open-ended responses, including: In quest: Meeting students' school-based needs via physical therapy; Seeking relatedness: Finding working teams in the school system; Building understanding: Developing a voice/identity in the school context; Stretched beyond limits: Managing workloads; Networking: Coordinating services outside school to meet student needs; Defying definition: What does working in an educational model mean? School-based physical therapists seek to meet educationally relevant physical therapy needs of students, ages 3 to 21 years. Successes appear woven of a multitude of factors such as therapist expertise, team dynamics, and district supports.

The Effects of Gender and Type of Inquiry Curriculum on Sixth Grade Students' Science Process Skills and Epistemological Beliefs in Science

NASA Astrophysics Data System (ADS)

Zaleta, Kristy L.

The purpose of this study was to investigate the impact of gender and type of inquiry curriculum (open or structured) on science process skills and epistemological beliefs in science of sixth grade students. The current study took place in an urban northeastern middle school. The researcher utilized a sample of convenience comprised of 303 sixth grade students taught by four science teachers on separate teams. The study employed mixed methods with a quasi-experimental design, pretest-posttest comparison group with 17 intact classrooms of students. Students' science process skills and epistemological beliefs in science (source, certainty, development, and justification) were measured before and after the intervention, which exposed different groups of students to different types of inquiry (structured or open). Differences between comparison and treatment groups and between male and female students were analyzed after the intervention, on science process skills, using a two-way analysis of covariance (ANCOVA), and, on epistemological beliefs in science, using a two-way multivariate analysis of covariance (MANCOVA). Responses from two focus groups of open inquiry students were cycle coded and examined for themes and patterns. Quantitative measurements indicated that girls scored significantly higher on science process skills than boys, regardless of type of inquiry instruction. Neither gender nor type of inquiry instruction predicted students' epistemological beliefs in science after accounting for students' pretest scores. The dimension Development accounted for 10.6% of the variance in students' science process skills. Qualitative results indicated that students with sophisticated epistemological beliefs expressed engagement with the open-inquiry curriculum. Students in both the sophisticated and naive beliefs groups identified challenges with the curriculum and improvement in learning as major themes. The types of challenges identified differed between the groups: sophisticated beliefs group students focused on their insecurity of not knowing how to complete the activities correctly, and naive beliefs group students focused on the amount of work and how long it took them to complete it. The description of the improvement in learning was at a basic level for the naive beliefs group and at a more complex level for the sophisticated beliefs group. Implications for researchers and educators are discussed.

Using the prisms of gender and rank to interpret research collaboration power dynamics.

PubMed

Gaughan, Monica; Bozeman, Barry

2016-08-01

Collaboration is central to modern scientific inquiry, and increasingly important to the professional experiences of academic scientists. While the effects of collaboration have been widely studied, much less is understood about the motivations to collaborate and collaboration dynamics that generate scientific outcomes. A particular interest of this study is to understand how collaboration experiences differ between women and men, and the attributions used to explain these differences. We use a multi-method study of university Science, Technology, Engineering, and Mathematics faculty research collaborators. We employ 177 anonymous open-ended responses to a web-based survey, and 60 semi-structured interviews of academic scientists in US research universities. We find similarities and differences in collaborative activity between men and women. Open-ended qualitative textual analysis suggests that some of these differences are attributed to power dynamics - both general ones related to differences in organizational status, and in power dynamics related specifically to gender. In analysis of semi-structured interviews, we find that both status and gender were used as interpretive frames for collaborative behavior, with more emphasis placed on status than gender differences. Overall, the findings support that gender structures some part of the collaborative experience, but that status hierarchy exerts more clear effects.

Single molecule optical measurements of orientation and rotations of biological macromolecules.

PubMed

Shroder, Deborah Y; Lippert, Lisa G; Goldman, Yale E

2016-11-22

Subdomains of macromolecules often undergo large orientation changes during their catalytic cycles that are essential for their activity. Tracking these rearrangements in real time opens a powerful window into the link between protein structure and functional output. Site-specific labeling of individual molecules with polarized optical probes and measurement of their spatial orientation can give insight into the crucial conformational changes, dynamics, and fluctuations of macromolecules. Here we describe the range of single molecule optical technologies that can extract orientation information from these probes, review the relevant types of probes and labeling techniques, and highlight the advantages and disadvantages of these technologies for addressing specific inquiries.

Science, School Science, and School: Looking at Science Learning in Classrooms from the Perspective of Basil Bernstein's Theory of the Structure of Pedagogic Discourse

NASA Astrophysics Data System (ADS)

Campbell, Ralph Ian

This analytic paper asks one question: How does Basil Bernstein's concept of the structure of pedagogic discourse (SPD) contribute to our understanding of the role of teacher-student interactions in science learning in the classroom? Applying Bernstein's theory of the SPD to an analysis of current research in science education explores the structure of Bernstein's theory as a tool for understanding the challenges and questions related to current concerns about classroom science learning. This analysis applies Bernstein's theory of the SPD as a heuristic through a secondary reading of selected research from the past fifteen years and prompts further consideration of Bernstein's ideas. This leads to a reevaluation of the categories of regulative discourse (RD) and instructional discourse (ID) as structures that frame learning environments and the dynamics of student-teacher interactions, which determine learning outcomes. The SPD becomes a simple but flexible heuristic, offering a useful deconstruction of teaching and learning dynamics in three different classroom environments. Understanding the framing interactions of RD and ID provides perspectives on the balance of agency and expectation, suggesting some causal explanations for the student learning outcomes described by the authors. On one hand, forms of open inquiry and student-driven instruction may lack the structure to ensure the appropriation of desired forms of scientific thinking. On the other hand, well-designed pathways towards the understanding of fundamental concepts in science may lack the forms of more open-ended inquiry that develop transferable understanding. Important ideas emerge about the complex dynamics of learning communities, the materials of learning, and the dynamic role of the teacher as facilitator and expert. Simultaneously, the SPD as a flexible heuristic proves ambiguous, prompting a reevaluation of Bernstein's organization of RD and ID. The hierarchical structure of pedagogic discourse becomes a problematic distinction. Regulative discourse is often more instructional and instructional discourse more instrumental in shaping roles and relationships within the learning community. This analysis suggests an agenda for future classroom research and the education of teachers, capitalizing on the SPD as heuristic and reevaluating the ways that social dynamics and structures for domain-specific learning interact in the realization of classroom learning.

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.

Infusing Authentic Inquiry into Biotechnology

NASA Astrophysics Data System (ADS)

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 their understanding of biotechnology? As respondents explored numerous ideas in order to develop a workable research question, struggled to create a viable protocol, executed their experiment, and then evaluated their results, they commented on unexpected topics regarding the nature of science as well as specific content knowledge relating to their experiments. Four out of five participants reported they learned the most during authentic inquiry laboratory experience.

The inquiry continuum: Science teaching practices and student performance on standardized tests

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 need to be stressed in undergraduate methods classes. While this study focused on the various types of scientific inquiry by creating a continuum of scientific inquiry methodologies, research using the continuum needs to be conducted to determine the various teaching styles of successful teachers.

Inquiry projects in science teacher education: What can investigative experiences reveal about teacher thinking and eventual classroom practice?

NASA Astrophysics Data System (ADS)

Windschitl, Mark

2003-01-01

Science education reform documents emphasize the importance of inquiry experiences for young learners. This means that teachers must be prepared with the knowledge, skills, and habits of thinking to mentor their students through authentic investigations. This study examines how preservice teachers' inquiry experiences, in a science methods course, influenced and were influenced by their conceptions of inquiry. The study also assesses how these experiences were associated with eventual classroom practice. Six preservice secondary teachers were observed during a 2-month inquiry project and then followed into the classroom as they began a 9-week teaching practicum. Data revealed that participants' preproject conceptions of the inquiry process were related to the conduct and interpretation of their own inquiry project, and that the project experience modified the inquiry conceptions of those participants who already had sophisticated understandings of scientific investigations. Perhaps most importantly, the participants who eventually used guided and open inquiry during their student teaching were not those who had more authentic views of inquiry or reflected most deeply about their own inquiry projects, but rather they were individuals who had significant undergraduate or professional experiences with authentic science research. Finally, this article advocates that independent science investigations be part of preservice education and that these experiences should be scaffolded to prompt reflection specifically about the nature of inquiry and conceptually linked to ways in which inquiry can be brought into the K-12 classroom.

The Effect of Student-Centered Approaches on Students' Interest and Achievement in Science: Relevant Topic-Based, Open and Guided Inquiry-Based, and Discussion-Based Approaches

NASA Astrophysics Data System (ADS)

Kang, Jingoo; Keinonen, Tuula

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.

OpenSim: a musculoskeletal modeling and simulation framework for in silico investigations and exchange.

PubMed

Seth, Ajay; Sherman, Michael; Reinbolt, Jeffrey A; Delp, Scott L

Movement science is driven by observation, but observation alone cannot elucidate principles of human and animal movement. Biomechanical modeling and computer simulation complement observations and inform experimental design. Biological models are complex and specialized software is required for building, validating, and studying them. Furthermore, common access is needed so that investigators can contribute models to a broader community and leverage past work. We are developing OpenSim, a freely available musculoskeletal modeling and simulation application and libraries specialized for these purposes, by providing: musculoskeletal modeling elements, such as biomechanical joints, muscle actuators, ligament forces, compliant contact, and controllers; and tools for fitting generic models to subject-specific data, performing inverse kinematics and forward dynamic simulations. OpenSim performs an array of physics-based analyses to delve into the behavior of musculoskeletal models by employing Simbody, an efficient and accurate multibody system dynamics code. Models are publicly available and are often reused for multiple investigations because they provide a rich set of behaviors that enables different lines of inquiry. This report will discuss one model developed to study walking and applied to gain deeper insights into muscle function in pathological gait and during running. We then illustrate how simulations can test fundamental hypotheses and focus the aims of in vivo experiments, with a postural stability platform and human model that provide a research environment for performing human posture experiments in silico . We encourage wide adoption of OpenSim for community exchange of biomechanical models and methods and welcome new contributors.

Network neuroscience

Bassett, Danielle S; Sporns, Olaf

2017-01-01

Despite substantial recent progress, our understanding of the principles and mechanisms underlying complex brain function and cognition remains incomplete. Network neuroscience proposes to tackle these enduring challenges. Approaching brain structure and function from an explicitly integrative perspective, network neuroscience pursues new ways to map, record, analyze and model the elements and interactions of neurobiological systems. Two parallel trends drive the approach: the availability of new empirical tools to create comprehensive maps and record dynamic patterns among molecules, neurons, brain areas and social systems; and the theoretical framework and computational tools of modern network science. The convergence of empirical and computational advances opens new frontiers of scientific inquiry, including network dynamics, manipulation and control of brain networks, and integration of network processes across spatiotemporal domains. We review emerging trends in network neuroscience and attempt to chart a path toward a better understanding of the brain as a multiscale networked system. PMID:28230844

Single molecule optical measurements of orientation and rotations of biological macromolecules

Shroder, Deborah Y; Lippert, Lisa G; Goldman, Yale E

2016-01-01

The subdomains of macromolecules often undergo large orientation changes during their catalytic cycles that are essential for their activity. Tracking these rearrangements in real time opens a powerful window into the link between protein structure and functional output. Site-specific labeling of individual molecules with polarized optical probes and measuring their spatial orientation can give insight into the crucial conformational changes, dynamics, and fluctuations of macromolecules. Here we describe the range of single molecule optical technologies that can extract orientation information from these probes, we review the relevant types of probes and labeling techniques, and we highlight the advantages and disadvantages of these technologies for addressing specific inquiries.

Kenny, Gerard

2011-06-01

This article seeks to explore how the experience of love and its expression might inform and guide reflection and inquiry into love. Despite the importance of love in our personal and professional lives, it remains a topic that has further scope for inquiry within nursing circles. The article takes as its catalyst an encounter that emerged out of a piece of research that was exploring individuals' experiences of becoming healers and the journey they undertook. One participant spoke deeply and profoundly of his experience of love, which generated for me a personal, experiential, and intellectual process of inquiry. The article seeks to try and create a synthesis between rational inquiry and subjective experience. It explores W. B. Yeats's notion of a gyre, a spiral, as an image and metaphor for integrating different conceptions and understandings of love. It seeks to illustrate how a more integrated understanding of love may open up spaces of inquiry that are more flexible, creative, and spontaneous.

2013-10-01

We describe the Science Semester, a semester-long course block that integrates three science courses and a science education methods course for elementary teacher education majors, and examine prospective elementary teachers’ developing conceptions about inquiry, science teaching efficacy, and reflections on learning through inquiry. The Science Semester was designed to provide inquiry-oriented and problem-based learning experiences, opportunities to examine socially relevant issues through cross-disciplinary perspectives, and align with content found in elementary curricula and standards. By the end of the semester, prospective elementary teachers moved from naïve to intermediate understandings of inquiry and significantly increased self-efficacy for science teaching as measured on one subscore of the STEBI-B. Reflecting on the semester, prospective teachers understood and appreciated the goals of the course and the PBL format, but struggled with the open-ended and student-directed elements of the course.

Incorporating Inquiry into Upper-Level Homework Assignments: The Mini-Journal

NASA Astrophysics Data System (ADS)

Whittington, A. G.; Speck, A. K.; Witzig, S. B.; Abell, S. K.

2009-12-01

The U.S. National Science Education Standards provide guidelines for teaching science through inquiry, where students actively develop their understanding of science by combining scientific knowledge with reasoning and thinking skills. Inquiry activities include reading scientific literature, generating hypotheses, designing and carrying out investigations, interpreting data, and formulating conclusions. Inquiry-based instruction emphasizes questions, evidence, and explanation, the essential features of inquiry. As part of an NSF-funded project, “CUES: Connecting Undergraduates to the Enterprise of Science,” new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). We engage students in inquiry-based learning by presenting homework exercises as “mini-journal” articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the minijournal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. The key differences between the old and new formats include (i) the active participation of the students in defining the problem that they will pursue, (ii) the open-ended nature of the inquiry, such that students need to recognize when they have enough information to answer their question, (iii) presentation of results in graphical and tabular formats, and (iv) a written discussion of their findings. We present both the rationale for and concept of using mini-journal homeworks, and provide specific examples we are currently employing in classes. In addition, we explore the challenges (real and perceived) and successes associated with implementing such a technique, and examine student feedback comparing mini-journal and traditional homework formats from the same classes.

Teaching About Theory-Laden Observation to Secondary Students Through Manipulated Lab Inquiry Experience

NASA Astrophysics Data System (ADS)

Lau, Kwok-chi; Chan, Shi-lun

2013-10-01

This study seeks to develop and evaluate a modified lab inquiry approach to teaching about nature of science (NOS) to secondary students. Different from the extended, open-ended inquiry, this approach makes use of shorter lab inquiry activities in which one or several specific NOS aspects are manipulated deliberately so that students are compelled to experience and then reflect on these NOS aspects. In this study, to let students experience theory-laden observation, they were provided with different "theories" in order to bias their observations in the lab inquiry. Then, in the post-lab discussion, the teacher guided students to reflect on their own experience and explicitly taught about theory-ladenness. This study employs a quasi-experimental pretest-posttest design using the historical approach as the control group. The results show that the manipulated lab inquiry approach was much more effective than the historical approach in fostering students' theory-laden views, and it was even more effective when the two approaches were combined. Besides, the study also sought to examine the practical epistemological beliefs of students concerning theory-ladenness, but limited evidence could be found.

Creating Personal Meaning through Technology-Supported Science Inquiry Learning across Formal and Informal Settings

2012-01-01

In this paper, a novel approach to engaging students in personal inquiry learning is described, whereby they carry out scientific investigations that are personally meaningful and relevant to their everyday lives. The learners are supported by software that guides the inquiry process, extending from the classroom into the school grounds, home, or outdoors. We report on a case study of personal inquiry learning with 28 high school students on the topic of healthy eating. An analysis of how the personal inquiry was enacted in the classroom and at home, based on issues identified from a study of interviews with the students and their teacher, is provided. The outcomes showed that students were alerted to challenges associated with fieldwork and how they responded to the uncertainty and challenge of an open investigation. The study, moreover, raised an unexpected difficulty for researchers of finding the 'sweet spot' between scientifically objective but unengaging inquiry topics, and ones that are personally meaningful but potentially embarrassing. Implications for further research are shaped around ways of overcoming this difficulty.

This report will discuss one model developed to study walking and applied to gain deeper insights into muscle function in pathological gait and during running. We then illustrate how simulations can test fundamental hypotheses and focus the aims of in vivo experiments, with a postural stability platform and human model that provide a research environment for performing human posture experiments in silico. We encourage wide adoption of OpenSim for community exchange of biomechanical models and methods and welcome new contributors. PMID:25893160

Backwards Faded Scaffolding Impact on Pre-Service Teachers’ Cognition

2009-12-01

In response to national reform movements calling for future teachers to be prepared to design and deliver science instruction using the principles of inquiry in the context of Earth system science, we created and evaluated an innovative curriculum for specially designed courses for pre-service elementary education and secondary undergraduates based upon an inquiry-oriented teaching approach framed by the notions of backwards faded-scaffolding as an overarching theme for inquiry-oriented instruction. Students completed both structured- and open-inquiry projects using online scientific data bases, particularly those available from NASA, and presented the results of their investigations several times throughout the semester as a mini-science conference. Using a single-group, multiple-measures, quasi-experimental design, students demonstrated enhanced content knowledge of astronomy and inquiry as well as attitudes and self-efficacy toward teaching as measured by the Test of Astronomy STandards (TOAST), the Science Teaching Efficacy Belief Instrument - Version B, and the Attitudes Toward Science Inventory. We adopted a model of inquiry where: (i) students are engaged in questions; (ii) students are designing plans to pursue data; and (iii) students are generating and defending conclusions based on evidence they have collected. We developed an approach that is directly in contrast with the open inquiry “science fair” model to specifically use carefully scaffolded, shorter term inquiries, placing the most challenging aspects of “question generation” at the end of the lessons. In this model, during students' first experience with inquiry they are guided through the entire process, from research question to the appropriate content and format for a scientific conclusion. In their second experience, students generate their conclusions independently, with the previous experience set out as a guide for content and format. They are required to make sense of data that has been purposefully and logically planned, collected, and analyzed with instructor guidance. They construct and defend conclusions based upon evidence that is, effectively, given to them. By the time students reach their third inquiry they have been exposed to two experiences in which they were guided through the process of data collection and analysis. On this third inquiry data collection and analysis becomes an independent task. By the fourth inquiry, students have received explicit instruction on the connection between the research question or hypothesis, and the procedure undergone to address those questions three times. They are positioned to take responsibility for creating a plausible method for collecting data given a research prompt. By the fifth inquiry, students have now seen four examples of quality research questions andhypotheses, and their relationship to procedures, data collection and conclusions. At this point they are positioned to successfully conduct an entire inquiry cycle. This strategy is specifically designed to provide students with early success and a sense of how the pieces of the scientific process connect to each other.

Resendiz, Marisol; Chen, Yuanyuan; Öztürk, Nail C; Zhou, Feng C

2013-01-01

Epigenetic medicine is still in its infancy. To date, only a handful of diseases have documented epigenetic correlates upstream of gene regulation including cancer, developmental syndromes and late-onset diseases. The finding that epigenetic markers are dynamic and heterogeneous at tissue and cellular levels, combined with recent identification of a new form of functionally distinct DNA methylation has opened a wider window for investigators to pry into the epigenetic world. It is anticipated that many diseases will be elucidated through this epigenetic inquiry. In this review, we discuss the normal course of DNA methylation during development, taking alcohol as a demonstrator of the epigenetic impact of environmental factors in disease etiology, particularly the growth retardation and neurodevelopmental deficits of fetal alcohol spectrum disorders.

Yang, Kuay-Keng; Lee, Ling; Hong, Zuway-R.; Lin, Huann-shyang

2016-09-01

The purpose of this study was to explore the effectiveness of the creative inquiry-based science teaching on students' creative science thinking and science inquiry performance. A quasi-experimental design consisting one experimental group (N = 20) and one comparison group (N = 24) with pretest and post-test was conducted. The framework of the intervention focused on potential strategies such as promoting divergent and convergent thinking and providing an open, inquiry-based learning environment that are recommended by the literature. Results revealed that the experimental group students outperformed their counterparts in the comparison group on the performances of science inquiry and convergent thinking. Additional qualitative data analyses from classroom observations and case teacher interviews identified supportive teaching strategies (e.g. facilitating associative thinking, sharing impressive ideas, encouraging evidence-based conclusions, and reviewing and commenting on group presentations) for developing students' creative science thinking.

2014-10-01

Peer review is a significant component in scientific research. Introducing peer review into inquiry processes may be regarded as an aim to develop student understanding regarding quality in inquiries. This study examines student understanding in inquiry peer reviews among pre-university chemistry students, aged 16-17, when they enact a design of a mimicked scholarly peer review. This design is based on a model of a human activity system. Twenty-five different schools in Brazil, Germany, Poland and The Netherlands participated. The students (n = 880) conducted in small groups (n = 428) open inquiries on fermentation. All groups prepared an inquiry report for peer review. These reports were published on a website. Groups were randomly paired in an internet symposium, where they posted review comments to their peers. These responses were qualitatively analyzed on small groups' level of understanding regarding seven categories: inquiry question, hypothesis, management of control variables, accurate measurement, presenting results, reliability of results, discussion and conclusion. The mimicked scholarly review prompted a collective practice. Student understanding was significantly well on presenting results, discussion and conclusion, and significantly less on inquiry question and reliability of results. An enacted design, based on a model of a human activity system, created student understanding of quality in inquiries as well as an insight in a peer-reviewing practice. To what extent this model can be applied in a broader context of design research in science education needs further study.

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.

The Challenges of Science Inquiry Teaching for Pre-Service Teachers in Elementary Classrooms: Difficulties on and under the Scene

NASA Astrophysics Data System (ADS)

Yoon, Hye-Gyoung; Joung, Yong Jae; Kim, Mijung

2012-06-01

In the context of the emphasis on inquiry teaching in science education, this study looks into how pre-service elementary teachers understand and practise science inquiry teaching during field experience. By examining inquiry lesson preparation, practice, and reflections of pre-service elementary teachers, we attempt to understand the difficulties they encounter and what could result from those difficulties in their practice. A total of 16 seniors (fourth-year students) in an elementary teacher education program participated in this study. In our findings, we highlight three difficulties `on the lesson' that are related to teaching practices that were missing in the classrooms: (1) developing children's own ideas and curiosity, (2) guiding children in designing valid experiments for their hypotheses, (3) scaffolding children's data interpretation and discussion and another three difficulties `under the lesson' that are related to problems with the pre-service teachers' conceptualization of the task: (4) tension between guided and open inquiry, (5) incomplete understanding of hypothesis, and (6) lack of confidence in science content knowledge. Based on these findings, we discuss how these difficulties are complexly related in the pre-service teachers' understandings and action. Several suggestions for science teacher education for inquiry teaching, especially hypothesis-based inquiry teaching, are then explored.

Students' Participation in an Interdisciplinary, Socioscientific Issues Based Undergraduate Human Biology Major and Their Understanding of Scientific Inquiry

NASA Astrophysics Data System (ADS)

Eastwood, Jennifer L.; Sadler, Troy D.; Sherwood, Robert D.; Schlegel, Whitney M.

2013-06-01

The purpose of this study was to examine whether Socioscientific Issues (SSI) based learning environments affect university students' epistemological understanding of scientific inquiry differently from traditional science educational contexts. We identify and compare conceptions of scientific inquiry of students participating in an interdisciplinary, SSI-focused undergraduate human biology major (SSI) and those participating in a traditional biology major (BIO). Forty-five SSI students and 50 BIO students completed an open-ended questionnaire examining their understanding of scientific inquiry. Eight general themes including approximately 60 subthemes emerged from questionnaire responses, and the numbers of students including each subtheme in their responses were statistically compared between groups. A subset of students participated in interviews, which were used to validate and triangulate questionnaire data and probe students' understanding of scientific inquiry in relation to their majors. We found that both groups provided very similar responses, differing significantly in only five subthemes. Results indicated that both groups held generally adequate understandings of inquiry, but also a number of misconceptions. Small differences between groups supported by both questionnaires and interviews suggest that the SSI context contributed to nuanced understandings, such as a more interdisciplinary and problem-centered conception of scientific inquiry. Implications for teaching and research are discussed.

Pre-service elementary teachers' understanding of scientific inquiry and its role in school science

NASA Astrophysics Data System (ADS)

Macaroglu, Esra

The purpose of this research was to explore pre-service elementary teachers' developing understanding of scientific inquiry within the context of their elementary science teaching and learning. More specifically, the study examined 24 pre-service elementary teachers' emerging understanding of (1) the nature of science and scientific inquiry; (2) the "place" of scientific inquiry in school science; and (3) the roles and responsibilities of teachers and students within an inquiry-based learning environment. Data sources consisted primarily of student-generated artifacts collected throughout the semester, including pre/post-philosophy statements and text-based materials collected from electronic dialogue journals. Individual data sources were open-coded to identify concepts and categories expressed by students. Cross-comparisons were conducted and patterns were identified. Assertions were formed with these patterns. Findings are hopeful in that they suggest pre-service teachers can develop a more contemporary view of scientific inquiry when immersed in a context that promotes this perspective. Not surprisingly, however, the prospective teachers encountered a number of barriers when attempting to translate their emerging ideas into practice. More research is needed to determine which teacher preparation experiences are most powerful in supporting pre-service teachers as they construct a framework for science teaching and learning that includes scientific inquiry as a central component.

The effects of inquiry instruction on student learning in technology-based undergraduate chemistry laboratories

NASA Astrophysics Data System (ADS)

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 reported that looking for patterns was a common theme in the laboratories. Hypotheses were reported as rarely used by both treatment groups. These findings are significant because they indicate that inquiry activities positively affect attitudes toward science, gender equality, and contribute to the development of formal reasoning skills and process skills.

2014-08-01

Nursing education has a history of encouraging students to know their patients and to negotiate the in-between of art/science, person/profession, and intuition/evidence. Nurse-teachers know that students may abandon some values and practices when they encounter practice environments that are complex and have competing agendas. We are concerned that nursing knowledge is black-boxed, invisible and taken-for-granted, in healthcare settings. Our research explores how nursing students and nurses are constructing and enacting person-centred care in mental health education and practice. We want to understand the nursing standpoint on this significant ontological issue and to make nursing knowledge construction and utilization visible; illuminating how person-centred theory emerges from practice. The process involved four 3-hour group meetings and an individual follow-up telephone conversation. Students and nurses met at a tertiary-care mental health organization. Fourteen nurses (Registered Nurses and Registered Practical Nurses) and nursing students (Bachelor of Science in Nursing and Practical Nursing) participated in our inquiry. We used arts-informed narrative inquiry to explore experience through the arts such as metaphor, collage, poems, letters, and group conversations. The black-box is opened as the inquiry reveals how nursing knowledge is constructed, assumptions are challenged and new practices emerge. Our research is significant for education and for practice and is transferable to other populations and settings. Nurses are affirmed in person-centred values and practices that include partnership with those in their care, role modeling for colleagues and mentoring students and new nurses. Students participate in transferring their learning from school to practice, in the company of experienced colleagues; together they open the black-box to show how nurses conceptualize and enact person-centred care.

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 could provide valuable insights and further recommendations. Overall, this study has yielded information that may lead to changes in both practice and thinking related to inquiry-based teaching and learning.

Promoting Inquiry-Based Teaching in Laboratory Courses: Are We Meeting the Grade?

PubMed Central

Butler, Amy; Burke da Silva, Karen

2014-01-01

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized.

Argumentation in the Chemistry Laboratory: Inquiry and Confirmatory Experiments

NASA Astrophysics Data System (ADS)

Katchevich, Dvora; Hofstein, Avi; Mamlok-Naaman, Rachel

2013-02-01

One of the goals of science education is to provide students with the ability to construct arguments—reasoning and thinking critically in a scientific context. Over the years, many studies have been conducted on constructing arguments in science teaching, but only few of them have dealt with studying argumentation in the laboratory. Our research focuses on the process in which students construct arguments in the chemistry laboratory while conducting various types of experiments. It was found that inquiry experiments have the potential to serve as an effective platform for formulating arguments, owing to the features of this learning environment. The discourse during inquiry-type experiments was found to be rich in arguments, whereas that during confirmatory-type experiments was found to be sparse in arguments. The arguments, which were developed during the discourse of an open inquiry experiment, focus on the hypothesis-building stage, analysis of the results, and drawing appropriate conclusions.

Determinants of Benin elementary school science teachers' orientation toward inquiry-based instructional practices

NASA Astrophysics Data System (ADS)

Gado, Issaou

The Republic of Benin (West Africa) undertook a nationwide curriculum reform that put an emphasis on inquiry-based instructional practices. Little, if any, research has been conducted to explore factors that could be related to teachers' orientation toward inquiry instructional practices. The purpose of this research study was to investigate factors and concerns that determine Benin elementary school teachers' orientation toward the use of inquiry-based instruction in the teaching of science. The study followed a naturalistic inquiry methodology combining a correlational ex post facto design and an observational case-study design. The theory of Planned Behavior was the conceptual framework used to design the study. Two hundred (N = 200) elementary school teachers and three (n = 3) case study participants were purposively selected. Data was gathered via the Revised Science Attitude Scale (Thompson & Shrigley, 1986), the Science Teachers' Ideological Preference Scale (Jones & Harty, 1978), open-ended questions, interviews, and classroom observations using audiorecorders, videorecorders, and the researcher-contextualized version of the Observational System for the Analysis of Classroom Instruction (Hough, 1966). Qualitative and quantitative data provided a deeper understanding of participants' responses. Quantitative measures indicated that Benin elementary school teachers have positive attitudes toward school science, significant positive orientation toward both inquiry-based instruction and traditional non inquiry-based instruction, and higher orientation toward inquiry-based instruction than traditional non inquiry-based instruction. Attitude toward handling materials for investigations was found to significantly contribute to the prediction of participants' inquiry orientation. Qualitative analyses of participants' responses indicated that the expectations of educational leaders, individual motivation to comply with the program, a perceived control of the performance of inquiry-based activities, students' inquiry outcome expectancy or likelihood of occurrence in the classroom, the pedagogical structure of the program, and the student-centeredness of the program were potential motivational factors that could explain participants' orientation toward inquiry-based instruction. Four major concerns---lack of materials for teaching, lack of training in the process and strategy of inquiry, overloaded curriculum content, students' linguistic difficulties---were perceived obstacles in implementing inquiry-based instruction. Implications for transformative curriculum practices are discussed.

Open inquiry-based learning experiences: a case study in the context of energy exchange by thermal radiation

NASA Astrophysics Data System (ADS)

Pizzolato, Nicola; Fazio, Claudio; Rosario Battaglia, Onofrio

2014-01-01

An open inquiry (OI)-based teaching/learning experience, regarding a scientific investigation of the process of energy exchange by thermal radiation, is presented. A sample of upper secondary school physics teachers carried out this experience at the University of Palermo, Italy, in the framework of ESTABLISH, a FP7 European Project aimed at promoting and developing inquiry-based science education. The teachers had the opportunity to personally experience an OI-based learning activity, with the aim of exploring the pedagogical potentialities of this teaching approach to promote both the understanding of difficult concepts and a deeper view of scientific practices. The teachers were firstly engaged in discussions concerning real-life problematic situations, and then stimulated to design and carry out their own laboratory activities, aimed at investigating the process of energy exchange by thermal radiation. A scientific study on the energy exchange between a powered resistor and its surrounding environment, during the heating and cooling processes, was designed and performed. Here we report the phases of this experiment by following the teachers' perspective. A structured interview conducted both before and after the OI experience allowed us to analyze and point out the teachers' feedback from a pedagogical point of view. The advantages and limits of an OI-based approach to promote the development of more student-centred inquiry-oriented teaching strategies are finally discussed.

How can you capture cultural dynamics?

PubMed Central

Kashima, Yoshihisa

2014-01-01

Cross-cultural comparison is a critical method by which we can examine the interaction between culture and psychological processes. However, comparative methods tend to overlook cultural dynamics – the formation, maintenance, and transformation of cultures over time. The present article gives a brief overview of four different types of research designs that have been used to examine cultural dynamics in the literature: (1) cross-temporal methods that trace medium- to long-term changes in a culture; (2) cross-generational methods that explore medium-term implications of cultural transmission; (3) experimental simulation methods that investigate micro-level mechanisms of cultural dynamics; and (4) formal models and computer simulation methods often used to investigate long-term and macro-level implications of micro-level mechanisms. These methods differ in terms of level of analysis for which they are designed (micro vs. macro-level), scale of time for which they are typically used (short-, medium-, or long-term), and direction of inference (deductive vs. empirical method) that they imply. The paper describes examples of these methods, discuss their strengths and weaknesses, and point to their complementarity in inquiries about cultural change. Because cultural dynamics research is about meaning over time, issues deriving from interpretation of meaning and temporal distance between researchers and objects of inquiry can pose threats to the validity of the research and its findings. The methodological question about hermeneutic circle is recalled and further inquiries are encouraged. PMID:25309476

Can Dynamic Visualizations with Variable Control Enhance the Acquisition of Intuitive Knowledge?

NASA Astrophysics Data System (ADS)

Wichmann, Astrid; Timpe, Sebastian

2015-10-01

An important feature of inquiry learning is to take part in science practices including exploring variables and testing hypotheses. Computer-based dynamic visualizations have the potential to open up various exploration possibilities depending on the level of learner control. It is assumed that variable control, e.g., by changing parameters of a variable, leads to deeper processing (Chang and Linn 2013; de Jong and Njoo 1992; Nerdel 2003; Trey and Khan 2008). Variable control may be helpful, in particular, for acquiring intuitive knowledge (Swaak and de Jong 2001). However, it bares the risk of mental exhaustion and thus may have detrimental effects on knowledge acquisition (Sweller 1998). Students ( N = 118) from four chemistry classes followed inquiry cycles using the software Molecular Workbench (Xie and Tinker 2006). Variable control was varied across the conditions (1) No-Manipulation group and (2) Manipulation group. By adding a third condition, (3) Manipulation-Plus group, we tested whether adding an active hypothesis phase prepares students before changing parameters of a variable. As expected, students in the Manipulation group and Manipulation-Plus group performed better concerning intuitive knowledge ( d = 1.14) than students in the No-Manipulation group. On a descriptive level, results indicated higher cognitive effort in the Manipulation group and the Manipulation-Plus group than in the No-Manipulation group. Unexpectedly, students in the Manipulation-Plus group did not benefit from the active hypothesis phase (intuitive knowledge: d = .36). Findings show that students benefit from variable control. Furthermore, findings point toward the direction that variable control evokes desirable difficulties (Bjork and Linn 2006).

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 through a microscope can be created and supported. To illustrate the possibilities of these tools, we have designed two inquiries that engage learners in the study of Moon rock samples under the microscope, starting from general questions such as comparison of Moon rocks or determining the origin of meteorites. One is aimed at undergraduate Geology students; the second has been conceived for the general public. Science teachers can reuse these inquiries, adapt them as they need, or create completely new inquiries using nQuire's authoring tool. We will report progress and demonstrate the combination of these two on-line tools to create an open educational resource allowing educators to design and run science inquiries for Earth and planetary science in a range of settings from schools to universities.

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

NASA Astrophysics Data System (ADS)

Sibbernsen, Kendra J.

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

Giving children space: A phenomenological exploration of student experiences in space science inquiry

NASA Astrophysics Data System (ADS)

Horne, Christopher R.

This study explores the experiences of 4th grade students in an inquiry-based space science classroom. At the heart of the study lies the essential question: What is the lived experience of children engaged in the process of space science inquiry? Through the methodology of phenomenological inquiry, the author investigates the essence of the lived experience of twenty 4th grade students as well as the reflections of two high school students looking back on their 4th grade space science experience. To open the phenomenon more deeply, the concept of space is explored as an overarching theme throughout the text. The writings of several philosophers including Martin Heidegger and Hans-Georg Gadamer are opened up to understand the existential aspects of phenomenology and the act of experiencing the classroom as a lived human experience. The methodological structure for the study is based largely on the work of Max van Manen (2003) in his seminal work, Researching Lived Experience, which describes a structure of human science research. A narrative based on classroom experiences, individual conversations, written reflections, and group discussion provides insight into the students' experiences. Their stories and thoughts reveal the themes of activity , interactivity, and "inquiractivity," each emerging as an essential element of the lived experience in the inquiry-based space science classroom. The metaphor of light brings illumination to the themes. Activity in the classroom is associated with light's constant and rapid motion throughout the Milky Way and beyond. Interactivity is seen through students' interactions just as light's reflective nature is seen through the illumination of the planets. Finally, inquiractivity is connected to questioning, the principal aspect of the inquiry-based classroom just as the sun is the essential source of light in our solar system. As the era of No Child Left Behind fades, and the next generation of science standards emerge, the students' stories are viewed through the lens of the scientific practices found in A Framework for K-12 Science Education (The National Research Council, 2011). The critical challenge for elementary educators interacting with this text is to find the lived meaning of giving children space in an inquiry-based experience.

2010-10-01

Lessons learned during the first offering of a lab component of an intermediate astrophysics course at the University of Wisconsin-River Falls are discussed. The course enrolled students from a variety of majors. Students worked in mixed-gender, mixed-major collaborative groups. They explored cosmic rays through hands-on, inquiry-based activities that took them from classic, fundamental discoveries to open-ended questions of their own design. We find that students divided their labor and brought the various parts of their research project together with little or no discussion regarding the various pieces and how they inform each other. Aspects of the lab design helped disrupt some typical gender dynamics in that men did not dominate group discussions. However, men did dominate the hands-on activities of the lab.

Primary pre-service teachers' skills in planning a guided scientific inquiry

NASA Astrophysics Data System (ADS)

García-Carmona, Antonio; Criado, Ana M.; Cruz-Guzmán, Marta

2017-10-01

A study is presented of the skills that primary pre-service teachers (PPTs) have in completing the planning of a scientific inquiry on the basis of a guiding script. The sample comprised 66 PPTs who constituted a group-class of the subject Science Teaching, taught in the second year of an undergraduate degree in primary education at a Spanish university. The data was acquired from the responses of the PPTs (working in teams) to open-ended questions posed to them in the script concerning the various tasks involved in a scientific inquiry (formulation of hypotheses, design of the experiment, data collection, interpretation of results, drawing conclusions). Data were analyzed within the framework of a descriptive-interpretive qualitative research study with a combination of inter- and intra-rater methods, and the use of low-inference descriptors. The results showed that the PPTs have major shortcomings in planning the complete development of a guided scientific inquiry. The discussion of the results includes a number of implications for rethinking the Science Teaching course so that PPTs can attain a basic level of training in inquiry-based science education.

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 how students enrolled in the same course can have very different experiences with inquiry. In general, the effect of high-level inquiry was not negative, and in fact, was found to have some desirable effects on students.

Exploring the Complexities of Children's Inquiries in Science: Knowledge Production Through Participatory Practices

NASA Astrophysics Data System (ADS)

Siry, Christina

2013-12-01

Beginning with the assumption that young children are capable of producing unprecedented knowledges about science phenomena, this paper explores the complexities of children's inquiries within open-ended investigations. I ask two central questions: (1) how can we (teachers, researchers, and children themselves) use and build upon children's explorations in science in practice? and (2) what pedagogical approaches can position children as experts on their experiences to facilitate children's sense of ownership in the process of learning science? Six vignettes from a Kindergarten classroom are analyzed to elaborate the central claim of this work, which is that when children are engaged in collaborative open-ended activities, science emerges from their interactions. Open-ended structures allowed for teachers and children to facilitate further investigations collaboratively, and participatory structures mediated children's representations and explanations of their investigations. Evidence of children's interactions is used to illustrate the complexities of children's explorations, and pedagogical approaches that create the spaces for children to create knowledge are highlighted.

Mini-Journals: Incorporating Inquiry, Quantitative Skills and Writing into Homework Assignments for Geochemistry and Planetary Science

NASA Astrophysics Data System (ADS)

Whittington, A. G.; Speck, A.; Witzig, S.

2011-12-01

As part of an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors, fulfills the computing requirement by having 50% of the grade come from five spreadsheet-based homework assignments), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). Inquiry involves activities where the learner engages in scientifically oriented questions, gives priority to evidence in responding to questions, formulates explanations from evidence, connects explanations to scientific knowledge, and communicates and justifies explanations. We engage students in inquiry-based learning by presenting homework exercises as "mini-journal" articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the mini-journal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. Example assignments from Geochemistry include "Trace Element Partitioning During Mantle Melting and MORB Crystallization" and "Isotopic Investigations of Crustal Evolution in the Midcontinent US". The key differences between the old and new formats include (i) active participation of the students in defining the question/problem that they will pursue, within well-defined boundaries, (ii) open-ended nature of the inquiry, so that students need to recognize when they have enough information to answer their question, (iii) extensive spreadsheet manipulation and presentation of results in graphical and tabular formats, and (iv) a written discussion of their findings. Grading is weighted more towards how the problem was addressed, and how findings are presented and interpreted, and less on actual numerical answers. Survey responses from students indicate that they experience discomfort on being presented with an open-ended assignment, but like the freedom to define their own problem. Students also recognize that reading, writing and critical thinking skills employed in the minijournal format increase their understanding of content. The combination of calculation and writing components make these assignments particularly useful for classes designated as "computer-based", and/or "writing intensive" (or similar designations).

Narrative inquiry: Locating Aboriginal epistemology in a relational methodology.

PubMed

Barton, Sylvia S

2004-03-01

This methodology utilizes narrative analysis and the elicitation of life stories as understood through dimensions of interaction, continuity, and situation. It is congruent with Aboriginal epistemology formulated by oral narratives through representation, connection, storytelling and art. Needed for culturally competent scholarship is an experience of research whereby inquiry into epiphanies, ritual, routines, metaphors and everyday experience creates a process of reflexive thinking for multiple ways of knowing. Based on the sharing of perspectives, narrative inquiry allows for experimentation into creating new forms of knowledge by contextualizing diabetes from the experience of a researcher overlapped with experiences of participants--a reflective practice in itself. The aim of this paper is to present narrative inquiry as a relational methodology and to analyse critically its appropriateness as an innovative research approach for exploring Aboriginal people's experience living with diabetes. Narrative inquiry represents an alternative culture of research for nursing science to generate understanding and explanation of Aboriginal people's 'diabetic self' stories, and to coax open a window for co-constructing a narrative about diabetes as a chronic illness. The ability to adapt a methodology for use in a cultural context, preserve the perspectives of Aboriginal peoples, maintain the holistic nature of social problems, and value co-participation in respectful ways are strengths of an inquiry partial to a responsive and embodied scholarship.

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 subjects tended to associate inquiry learning exclusively in terms of exploring before lecture, getting a single correct answer. Additionally, various subjects at multiple levels, described inquiry in terms of the 5E Model of Instruction, which is emphasized in the Arkansas UTeach lesson design. Implications of these findings and suggestions for program improvement at the course levels are suggested.

Longitudinal studies in clinical psychoendocrinology: methodology.

Money, J

1986-02-01

There are five universal exigencies of being human, against which a person's existence can be evaluated: pairbondage, troopbondage, abidance, ycleptance, and foredoomance. They constitute a template from which a standardized agenda or schedule of inquiry is generated, as needed, for a particular research investigation. The schedule of inquiry is painstakingly designed ahead of time so as to ensure coverage of all the variables relevant to a particular study. For economy of expense and effort, subjects conclude their own prior interviews by summarizing it on tape, with the interviewer making a written record, verbatim, of what will become subheadings in the transcript. Inquiry progresses from an open-ended to a forced choice interrogatory. Topics in the public domain open the way to inquiry on personally sensitive issues. So also do parables drawn from actual cases and used as personalized narrative projective tests. A cumulative record, covering as many as 25 years, is indexed so that relevant material can be located, abstracted, and classified for any particular study. A jury of two or more then uses the abstracted data to fill out a prepared data schedule, using its own standardized scoring or rating criteria. By contrast, an ordinary questionnaire uses standardized questions, and each subject applies his or her own unstandardized scoring or rating criteria in answering them. In the final step, the jury's ratings are tabulated on a master chart that consolidates the scores of a group of subjects and controls, ready for statistical analysis.

Challenges and Support When Teaching Science Through an Integrated Inquiry and Literacy Approach

NASA Astrophysics Data System (ADS)

Ødegaard, Marianne; Haug, Berit; Mork, Sonja M.; Ove Sørvik, Gard

2014-12-01

In the Budding Science and Literacy project, we explored how working with an integrated inquiry-based science and literacy approach may challenge and support the teaching and learning of science at the classroom level. By studying the inter-relationship between multiple learning modalities and phases of inquiry, we wished to illuminate possible dynamics between science inquiry and literacy in an integrated science approach. Six teachers and their students were recruited from a professional development course for the current classroom study. The teachers were to try out the Budding Science teaching model. This paper presents an overall video analysis of our material demonstrating variations and patterns of inquiry-based science and literacy activities. Our analysis revealed that multiple learning modalities (read it, write it, do it, and talk it) are used in the integrated approach; oral activities dominate. The inquiry phases shifted throughout the students' investigations, but the consolidating phases of discussion and communication were given less space. The data phase of inquiry seems essential as a driving force for engaging in science learning in consolidating situations. The multiple learning modalities were integrated in all inquiry phases, but to a greater extent in preparation and data. Our results indicate that literacy activities embedded in science inquiry provide support for teaching and learning science; however, the greatest challenge for teachers is to find the time and courage to exploit the discussion and communication phases to consolidate the students' conceptual learning.

Inquiry-based Science Instruction in High School Biology Courses: A Multiple Case Study

NASA Astrophysics Data System (ADS)

Aso, Eze

A lack of research exists about how secondary school science teachers use inquiry-based instruction to improve student learning. The purpose of this qualitative study was to explore how science teachers used inquiry-based instruction to improve student learning in high school biology courses. The conceptual framework was based on Banchi and Bell's model of increasing levels of complexity for inquiry-based instruction. A multiple case study research design was conducted of biology programs at 3 high schools in an urban school district in the northeastern region of the United States. Participants included 2 biology teachers from each of the 3 high schools. Data were collected from individual interviews with biology teachers, observations of lessons in biology, and documents related to state standards, assessments, and professional development. The first level of data analysis involved coding and categorizing the interview and observation data. A content analysis was used for the documents. The second level of data analysis involved examining data across all sources and all cases for themes and discrepancies. According to study findings, biology teachers used confirmation, structure, and guided inquiry to improve student learning. However, they found open inquiry challenging and frustrating to implement because professional development about scaffolding of instruction over time was needed, and students' reading and writing skills needed to improve. This study contributes to positive social change by providing educators and researchers with a deeper understanding about how to scaffold levels of inquiry-based science instruction in order to help students become scientifically literate citizens.

This study was conducted to illustrate that nonlinear dynamic variables of Traditional Chinese Medicine (TCM) pulse can improve the performances of TCM Zheng classification models. Pulse recordings of 334 coronary heart disease (CHD) patients and 117 normal subjects were collected in this study. Recurrence quantification analysis (RQA) was employed to acquire nonlinear dynamic variables of pulse. TCM Zheng models in CHD were constructed, and predictions using a novel multilabel learning algorithm based on different datasets were carried out. Datasets were designed as follows: dataset1, TCM inquiry information including inspection information; dataset2, time-domain variables of pulse and dataset1; dataset3, RQA variables of pulse and dataset1; and dataset4, major principal components of RQA variables and dataset1. The performances of the different models for Zheng differentiation were compared. The model for Zheng differentiation based on RQA variables integrated with inquiry information had the best performance, whereas that based only on inquiry had the worst performance. Meanwhile, the model based on time-domain variables of pulse integrated with inquiry fell between the above two. This result showed that RQA variables of pulse can be used to construct models of TCM Zheng and improve the performance of Zheng differentiation models. PMID:23737839

Despite advances to move anatomy education away from its didactic history, there is a continued need for students to contextualize their studies to make learning more meaningful. This article investigates authentic learning in the context of an inquiry-based approach to learning human gross anatomy. Utilizing a case-study design with three groups of students (n = 18) and their facilitators (n = 3), methods of classroom observations, interviews, and artifact collection were utilized to investigate students' experiences of learning through an inquiry project. Qualitative data analysis through open and selective coding produced common meaningful themes of group and student experiences. Overall results demonstrate how the project served as a unique learning experience where learners engaged in the opportunity to make sense of anatomy in context of their interests and wider interdisciplinary considerations through collaborative, group-based investigation. Results were further considered in context of theoretical frameworks of inquiry-based and authentic learning. Results from this study demonstrate how students can engage anatomical understandings to inquire and apply disciplinary considerations to their personal lives and the world around them.

Using a Module-based Laboratory To Incorporate Inquiry into a Large Cell Biology Course

PubMed Central

2005-01-01

Because cell biology has rapidly increased in breadth and depth, instructors are challenged not only to provide undergraduate science students with a strong, up-to-date foundation of knowledge, but also to engage them in the scientific process. To these ends, revision of the Cell Biology Lab course at the University of Wisconsin–La Crosse was undertaken to allow student involvement in experimental design, emphasize data collection and analysis, make connections to the “big picture,” and increase student interest in the field. Multiweek laboratory modules were developed as a method to establish an inquiry-based learning environment. Each module utilizes relevant techniques to investigate one or more questions within the context of a fictional story, and there is a progression during the semester from more instructor-guided to more open-ended student investigation. An assessment tool was developed to evaluate student attitudes regarding their lab experience. Analysis of five semesters of data strongly supports the module format as a successful model for inquiry education by increasing student interest and improving attitude toward learning. In addition, student performance on inquiry-based assignments improved over the course of each semester, suggesting an improvement in inquiry-related skills. PMID:16220145

Group learning capacity: the roles of open-mindedness and shared vision

PubMed Central

Lord, Mimi

2015-01-01

Open-mindedness (OPM) is a construct that is considered a key foundational aspect of learning in individuals, groups and organizations. Also known as critical inquiry or reflection, OPM is believed to increase learning through examination of prior beliefs, decisions and mistakes, and also through openness to new ideas. Renowned theorists including Dewey and Argyris have emphasized the relationship between OPM and learning, yet little quantitative research has tested it or examined moderators of the linkage. The setting for the current study is that of endowment investment committees at U.S. universities and colleges who need to make knowledgeable and well-reasoned decisions about the composition of investment portfolios. Findings indicate that OPM has a positive, significant effect on group learning capacity (LCAP) and also that shared vision, which represents the group's collective purpose and direction, moderates that relationship. The literature review and discussion offer insights about how OPM is related to the research on group conflict, and how shared vision (SHV) differs from concepts such as interpersonal cohesiveness and conformity that have been associated with groupthink. A review of relevant research from the fields of organizational learning, group dynamics, and absorptive capacity provides context for the development of the hypotheses and the discussion of findings.

Mapping Science in Discourse-based Inquiry Classrooms

NASA Astrophysics Data System (ADS)

Yeneayhu, Demeke Gesesse

Abstract The purpose of this study was to investigate how discourse-based inquiry science lessons provided opportunities for students to develop a network of semantic relations among core ideas and concepts in science. It was a naturalistic inquiry classroom lessons observation study on three science teachers--- a middle school science teacher and two high school physics teachers in an urban school district located in the Western New York region. Discourse and thematic analysis drawn from the theory of Systemic Functional Linguistics were utilized as guiding framework and analysis tools. Analysis of the pre-observation and post-observation interviews of the participant teachers revealed that all of the three teachers participated in at least one inquiry-based science teaching teacher professional development program and they all thought their classroom teaching practice was inquiry-based. Analysis of their classroom lesson videos that each participant teacher taught on a specific science topic revealed that the middle school teacher was found to be a traditional teacher-dominated classroom whereas the two high school physics teachers' classroom teaching approach was found to be discourse-based inquiry. One of the physics teachers who taught on a topic of Magnetic Interaction used relatively structured and guided-inquiry classroom investigations. The other physics teacher who taught on a topic of Color Mixing utilized open-ended classroom investigations where the students planned and executed the series of classroom science investigations with minimal guidance from the teacher. The traditional teacher-based classroom communicative pattern was found to be dominated by Triadic Dialogue and most of the science thematics were jointly developed by the teacher and the students, but the students' role was limited to providing responses to the teacher's series questions. In the guided-inquiry classroom, the common communicative pattern was found to be True Dialogue and most of the science thematic patterns in the lessons were not only developed by the students but also resemble the standard thematics. Similarly, in the open-ended inquiry classroom, True Dialogue and Cross-discussion were the two most common communicative patterns and students did most of the science thematic patterns in the lessons but most of the student thematics were commonsense than resembling the standard thematics on the topic. This research showed that if teachers are to help students participate in classroom discourse that would enable them meaningfully connects core ideas and concepts in science, teachers could use various discourse tools and pedagogic resources that could fit into their particular classroom realities and contexts. This study demonstrated that when given the opportunity, students in challenging contexts such in typical inner city schools are able to engage in scientific processes and develop nuanced understandings of scientific phenomena.

Incorporating Inquiry into Upper-Level Undergraduate Homework Assignments: The Mini-Journal

NASA Astrophysics Data System (ADS)

Whittington, Alan; Speck, Angela; Witzig, Stephen; Abell, Sandra

2010-05-01

The US National Science Education Standards (2000) state that science should be taught through inquiry. The five essential features of classroom inquiry are that the leaner (i) engages in scientifically oriented questions, (ii) gives priority to evidence in responding to questions, (iii) formulates explanations from evidence, (iv) connects explanations to scientific knowledge, and (v) communicates and justifies explanations. One difficulty in achieving this vision at the university level lies in the common perception that inquiry be fully open and unstructured, and that its implementation will be impractical due to time and material constraints. In an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," faculty developed new inquiry-based laboratory curriculum materials using a "mini-journal" approach, which is designed as an alternative to the cookbook laboratory and represents the way that scientists do science. Here we adapt this approach to a homework assignment in an upper-level Planetary Science class, and show that inquiry is achievable in this setting. Traditional homeworks in this class consisted of problem sets requiring algebraic manipulation, computation, and in most cases an appraisal of the result Longer questions are broken down into chunks worth 1 to 4 points. In contrast, the mini-journal is a short article that is modeled in the way that scientists do and report science. It includes a title, abstract, introduction (with clear statement of the problem to be tackled), a description of the methods, results (presented as both tables and graphs), a discussion (with suggestions for future work) and a list of cited work. Students devise their research questions and hypothesis from the paper based on a logical next step in the investigation. Guiding questions in the discussion can assist the students ("it would be interesting to evaluate the effect of ..."). Students submit their own minijournal, using the same journal-style format. A detailed grading rubric was supplied with the mini-journal, with credit given for formatting, accuracy of calculation, and quality of intepretation and discussion. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. The key differences between the old and new formats include (i) the active participation of the students in defining the problem that they will pursue, (ii) the open-ended nature of the inquiry, such that students need to recognize when they have enough information to answer their question, (iii) presentation of results in graphical and tabular formats, and (iv) a written discussion of their findings. Based on detailed student and instructor feedback, our conclusions are: (i) Limited inquiry is achievable in upper-level science homework assignments, and is transferable to other topics and classes (ii) Students experience discomfort on being presented with an open-ended assignment, but like the freedom to define their own homework problem (iii) Students recognize that the reading, writing and critical thinking skills employed in the minijournal format increase their understanding (iv) Students suggest a combination of minijournal and traditional homework formats in this class, or replacing midterm exams with minijournals (v) Student written comments are far more useful than Likert scale responses in assessing instructional techniques and effectiveness

Dancing with data: an example of acquiring theoretical sensitivity in a grounded theory study.

Glaser suggested that the conceptual route from data collection to a grounded theory is a set of double back steps. The route forward inevitably results in the analyst stepping back. Additionally sidestepping through, leading participants down lines of inquiry and following data threads with other participants, is also characteristic of acquiring theoretical sensitivity, a key concept in grounded theory. Other ways of acquiring theoretical sensitivity comprise: reading the literature, open coding, category building, reflecting in memos followed by doubling back on data collection once further lines of inquiry are opened up. This paper describes how we 'danced with data' in pursuit of heightened theoretical sensitivity in a grounded theory study of information use by nurses working in general practice in New Zealand. Providing an example of how analytical tools are employed to theoretically sample emerging concepts. © 2012 Blackwell Publishing Asia Pty Ltd.

The Impact of High School Science Teachers' Beliefs, Curricular Enactments and Experience on Student Learning During an Inquiry-based Urban Ecology Curriculum

McNeill, Katherine L.; Silva Pimentel, Diane; Strauss, Eric G.

2013-10-01

Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers' use of a year-long high school urban ecology curriculum and how teachers' self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.

Testing an idealized dynamic cascade model of the development of serious violence in adolescence.

PubMed

Dodge, Kenneth A; Greenberg, Mark T; Malone, Patrick S

2008-01-01

A dynamic cascade model of development of serious adolescent violence was proposed and tested through prospective inquiry with 754 children (50% male; 43% African American) from 27 schools at 4 geographic sites followed annually from kindergarten through Grade 11 (ages 5-18). Self, parent, teacher, peer, observer, and administrative reports provided data. Partial least squares analyses revealed a cascade of prediction and mediation: An early social context of disadvantage predicts harsh-inconsistent parenting, which predicts social and cognitive deficits, which predicts conduct problem behavior, which predicts elementary school social and academic failure, which predicts parental withdrawal from supervision and monitoring, which predicts deviant peer associations, which ultimately predicts adolescent violence. Findings suggest targets for in-depth inquiry and preventive intervention.

The Structure of Scientific Arguments by Secondary Science Teachers: Comparison of experimental and historical science topics

NASA Astrophysics Data System (ADS)

Gray, Ron; Kang, Nam-Hwa

2014-01-01

Just as scientific knowledge is constructed using distinct modes of inquiry (e.g. experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction differently for topics that rely on experimental or historical modes of inquiry. Four experienced high-school science teachers were observed daily during instructional units for both experimental and historical science topics. The main data sources include classroom observations and teacher interviews. The arguments were analyzed using Toulmin's argumentation pattern revealing specific patterns of arguments in teaching topics relying on these 2 modes of scientific inquiry. The teachers presented arguments to their students that were rather simple in structure but relatively authentic to the 2 different modes. The teachers used far more evidence in teaching topics based on historical inquiry than topics based on experimental inquiry. However, the differences were implicit in their teaching. Furthermore, their arguments did not portray the dynamic nature of science. Very few rebuttals or qualifiers were provided as the teachers were presenting their claims as if the data led straightforward to the claim. Implications for classroom practice and research are discussed.

Exploring students' interactions, arguments, and reflections in general chemistry laboratories with different levels of inquiry

NASA Astrophysics Data System (ADS)

Xu, Haozhi

Students' learning in inquiry-based investigations has drawn considerable attention of the science education community. Inquiry activities can be viewed as knowledge construction processes in which students are expected to develop conceptual understanding and critical thinking abilities. Our study aimed to explore the effect of experiments with different levels of inquiry on students' interactions in the laboratory setting, as well as on students' written arguments and reflections. Our results are based on direct observations of group work in college general chemistry laboratories and analysis of associated written lab reports. The analysis of students' interactions in the laboratory was approached from three major analytic dimensions: Functional analysis, cognitive processing, and social processing. According to our results, higher levels of inquiry were associated with an increase in the relative frequency of episodes where students were engaged in proposing ideas versus asking and answering each others' questions. Higher levels of inquiry also favored episodes in which experimental work was approached in a more exploratory (versus procedural) manner. However, no major changes were observed in the extent to which students were engaged in either interpretive discussions of central scientific concepts and ideas. As part of our study we were also interested in characterizing the effects of experiments involving different levels of inquiry on the structure and adequacy of university general chemistry students' written arguments, as well as on the nature of their reflections about laboratory work. Our findings indicate that the level of inquiry of the observed experiments had no significant impact on the structure or adequacy of arguments generated by students. However, the level of inquiry of the experiments seemed to have a major impact on several areas of students' written reflections about laboratory work. In general, our results elicit trends and highlight issues that can help instructors and curriculum developers identify strategies to better support and scaffold productive engagement in the laboratory. Our results suggest that careful design and implementation of instructional interventions may be needed to maximize the learning effects of the more open-ended inquiry activities at the college level.

We describe a structured inquiry laboratory exercise that examines transcriptional regulation of the NOS2 gene under conditions that simulate the inflammatory response in macrophages. Using quantitative PCR and the comparative CT method, students are able determine whether transcriptional activation of NOS2 occurs and to what degree. The exercise is aimed at second year undergraduates who possess basic knowledge of gene expression events. It requires only 4-5 hr of dedicated laboratory time and focuses on use of the primary literature, data analysis, and interpretation. Importantly, this exercise provides a mechanism to introduce the concept of differential gene expression and provides a starting point for development of more complex guided or open inquiry projects for students moving into upper level molecular biology, immunology, and biochemistry course work. © 2015 The International Union of Biochemistry and Molecular Biology.

A Comparison of Student Understanding of Seasons Using Inquiry and Didactic Teaching Methods

Ashcraft, Paul G.

2006-02-01

Student performance on open-ended questions concerning seasons in a university physical science content course was examined to note differences between classes that experienced inquiry using a 5-E lesson planning model and those that experienced the same content with a traditional, didactic lesson. The class examined is a required content course for elementary education majors and understanding the seasons is part of the university's state's elementary science standards. The two self-selected groups of students showed no statistically significant differences in pre-test scores, while there were statistically significant differences between the groups' post-test scores with those who participated in inquiry-based activities scoring higher. There were no statistically significant differences between the pre-test and the post-test for the students who experienced didactic teaching, while there were statistically significant improvements for the students who experienced the 5-E lesson.

Project CUES is a middle-school earth systems science curriculum project under development by the American Geological Institute (AGI) and funded by the National Science Foundation (ESI-0095938). CUES features a student-centered, inquiry pedagogy and approaches earth science from a systems perspective. CUES will use the expanded learning cycle approach of Trowbridge and Bybee (1996), known as the 5E model (engage-explore-explain-elaborate-evaluate). Unlike AGI's Investigating Earth Systems (IES) curriculum modules, CUES will include a single hard-bound textbook, and will take one school-year to complete. The textbook includes a prologue that addresses systems concepts and four main units: Geosphere, Hydrosphere, Atmosphere, and Biosphere. Each eight-week unit takes students through a progression from guided inquiry to open-ended, student-driven inquiry. During first 4 to 5 weeks of each unit, students explore important earth science phenomena and concepts through scripted investigations and narrative reading passages written by scientists as "inquiry narratives". The narratives address the development of scientific ideas and relay the personal experiences of a scientist during their scientific exploration. Aspects of the nature of science will be explicitly addressed in investigations and inquiry narratives. After the guided inquiry, students will develop a research proposal and conduct their own inquiry into local or regional scientific problems. Each unit culminates with a science conference at which students present their research. CUES will be the first NSF-funded, comprehensive earth systems textbook for middle school that is based on national standards. CUES will be pilot tested in 12 classrooms in January 2003, with a national field test of the program in 50 classrooms during the 2003-2004 school year.

Supporting Knowledge Integration in Chemistry with a Visualization-Enhanced Inquiry Unit

NASA Astrophysics Data System (ADS)

Chiu, Jennifer L.; Linn, Marcia C.

2014-02-01

This paper describes the design and impact of an inquiry-oriented online curriculum that takes advantage of dynamic molecular visualizations to improve students' understanding of chemical reactions. The visualization-enhanced unit uses research-based guidelines following the knowledge integration framework to help students develop coherent understanding by connecting and refining existing and new ideas. The inquiry unit supports students to develop connections among molecular, observable, and symbolic representations of chemical reactions. Design-based research included a pilot study, a study comparing the visualization-enhanced inquiry unit to typical instruction, and a course-long comparison study featuring a delayed posttest. Students participating in the visualization-enhanced unit outperformed students receiving typical instruction and further consolidated their understanding on the delayed posttest. Students who used the visualization-enhanced unit formed more connections among concepts than students with typical textbook and lecture-based instruction. Item analysis revealed the types of connections students made when studying the curriculum and suggested how these connections enabled students to consolidate their understanding as they continued in the chemistry course. Results demonstrate that visualization-enhanced inquiry designed for knowledge integration can improve connections between observable and atomic-level phenomena and serve students well as they study subsequent topics in chemistry.

`Just Be Quiet and Listen to Exactly What He's Saying': Conceptualising power relations in inquiry-oriented classrooms

Donnelly, Dermot Francis; McGarr, Oliver; O'Reilly, John

2014-08-01

Interest in inquiry-based science education (IBSE) often pays little heed to the complex power relations that exist within classrooms. A common obstacle to inquiry is that it strongly diverges from current classroom culture and hence, is outside the sphere of teachers' and students' experiences. Teachers and students bring expectations to the classroom that are entrenched in traditional practices and influenced by dynamics of power that exist within all teacher-student relationships. This study, which emerged during a wider study of the use of a Virtual Chemistry Lab in supporting IBSE, explores how classroom discourse constructs and maintains power relations that either stifle or facilitate inquiry-based approaches in two science lessons. Research methods included teacher interviews, student focus groups, video-recorded lessons, and student self-assessments. Findings indicate distinctive features of power inside the classroom that impact on inquiry-based instruction, such as predominant teacher monitoring on task completion over task understanding, lack of student engagement in ownership of scientific ideas, and prevailing norms of what effective teacher questioning is. We discuss implications for IBSE change efforts, highlighting that well-established power relations currently represent an important limiting factor in the capacity of teachers' IBSE implementation.

In this article, we will shortly review a few old thoughts and recent thoughts on the relation between Mathematics and the Natural Sciences. Of course, the classic references to this open problem will include Wigner's paper (1964); a more recent review article is Darvas (2008). But it appears that this issue is partly on the domain of natural philosophy and also philosophy of inquiry. Therefore we will begin with a review on some known thoughts of Kant, Bacon, Popper, etc. Our hope here is to find out clues to reveal the hidden structure of Nature, just as what Planck did a century ago.

Promoting inquiry-based teaching in laboratory courses: are we meeting the grade?

PubMed

Beck, Christopher; Butler, Amy; da Silva, Karen Burke

2014-01-01

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized. © 2014 C.

Supporting students' knowledge integration with technology-enhanced inquiry curricula

NASA Astrophysics Data System (ADS)

Chiu, Jennifer Lopseen

Dynamic visualizations of scientific phenomena have the potential to transform how students learn and understand science. Dynamic visualizations enable interaction and experimentation with unobservable atomic-level phenomena. A series of studies clarify the conditions under which embedding dynamic visualizations in technology-enhanced inquiry instruction can help students develop robust and durable chemistry knowledge. Using the knowledge integration perspective, I designed Chemical Reactions, a technology-enhanced curriculum unit, with a partnership of teachers, educational researchers, and chemists. This unit guides students in an exploration of how energy and chemical reactions relate to climate change. It uses powerful dynamic visualizations to connect atomic level interactions to the accumulation of greenhouse gases. The series of studies were conducted in typical classrooms in eleven high schools across the country. This dissertation describes four studies that contribute to understanding of how visualizations can be used to transform chemistry learning. The efficacy study investigated the impact of the Chemical Reactions unit compared to traditional instruction using pre-, post- and delayed posttest assessments. The self-monitoring study used self-ratings in combination with embedded assessments to explore how explanation prompts help students learn from dynamic visualizations. The self-regulation study used log files of students' interactions with the learning environment to investigate how external feedback and explanation prompts influence students' exploration of dynamic visualizations. The explanation study compared specific and general explanation prompts to explore the processes by which explanations benefit learning with dynamic visualizations. These studies delineate the conditions under which dynamic visualizations embedded in inquiry instruction can enhance student outcomes. The studies reveal that visualizations can be deceptively clear, deterring learners from exploring details. Asking students to generate explanations helps them realize what they don't understand and can spur students to revisit visualizations to remedy gaps in their knowledge. The studies demonstrate that science instruction focused on complex topics can succeed by combining visualizations with generative activities to encourage knowledge integration. Students are more successful at monitoring their progress and remedying gaps in knowledge when required to distinguish among alternative explanations. The results inform the design of technology-enhanced science instruction for typical classrooms.

Student leadership in small group science inquiry

NASA Astrophysics Data System (ADS)

Oliveira, Alandeom W.; Boz, Umit; Broadwell, George A.; Sadler, Troy D.

2014-09-01

Background: Science educators have sought to structure collaborative inquiry learning through the assignment of static group roles. This structural approach to student grouping oversimplifies the complexities of peer collaboration and overlooks the highly dynamic nature of group activity. Purpose: This study addresses this issue of oversimplification of group dynamics by examining the social leadership structures that emerge in small student groups during science inquiry. Sample: Two small student groups investigating the burning of a candle under a jar participated in this study. Design and method: We used a mixed-method research approach that combined computational discourse analysis (computational quantification of social aspects of small group discussions) with microethnography (qualitative, in-depth examination of group discussions). Results: While in one group social leadership was decentralized (i.e., students shared control over topics and tasks), the second group was dominated by a male student (centralized social leadership). Further, decentralized social leadership was found to be paralleled by higher levels of student cognitive engagement. Conclusions: It is argued that computational discourse analysis can provide science educators with a powerful means of developing pedagogical models of collaborative science learning that take into account the emergent nature of group structures and highly fluid nature of student collaboration.

Impact of National Assessment of Educational Progress (NAEP) use and score interpretation on states' inquiry-based science education policies and practices: A descriptive study

NASA Astrophysics Data System (ADS)

Conley, David M.

This study examined the influence of use and interpretation of National Assessment of Educational Progress (NAEP) science results on science education policies and practices in the United States, in the context of teaching and learning through inquiry and the assessment of student inquiry achievement. State assessment directors, NAEP coordinators, and science education specialists nationwide were invited to participate in the study by responding to a Web-based self-administered survey instrument. Sixty-seven percent of the population responded, providing both quantitative and qualitative data through selected-response and open-ended survey items, respectively. The findings of this study revealed that: (a) not all states interpret NAEP science results as an indicator of students' abilities to undertake inquiry investigations or understand the nature of inquiry---in fact, states view their own science assessments as more indicative of expectations regarding inquiry achievement; (b) most states have made changes to science curricular frameworks and assessments since the last NAEP science administration in 2000, so that more emphasis is placed on inquiry-based instruction and assessment of inquiry achievement---however, NAEP results have had a minor influence on these changes; (c) fewer states have made changes in legislation, policies, and professional development that reflect greater emphasis on inquiry, and those that did felt that NAEP results had no significant impact; (d) NAEP's influence has changed since the No Child Left Behind (NCLB) Act of 2001, but it remains minor since NAEP is still perceived as a "low stakes" test; (e) state officials believe NAEP's influence will increase significantly after the results of NAEP science 2005 are released and interpreted and as NCLB accountability provisions in science take hold in 2007--2008. The implications of the study's findings are discussed in reference to the theoretical and practical knowledge-bases concerning the consequences of assessment; the interpretation and use of future NAEP results to inform state science education systems; and NAEP validity studies and revisions to the NAEP assessment framework that may ensue. Limitations of the study's findings and directions for future research are also addressed.

The Departmental Script as an Ongoing Conversation into the Phronesis of Teaching Science as Inquiry

NASA Astrophysics Data System (ADS)

Melville, Wayne; Campbell, Todd; Fazio, Xavier; Bartley, Anthony

2012-12-01

This article investigates the extent to which a science department script supports the teaching and learning of science as inquiry and how this script is translated into individual teachers' classrooms. This study was completed at one school in Canada which, since 2000, has developed a departmental script supportive of teaching and learning of science as inquiry. Through a mixed-method strategy, multiple data sources were drawn together to inform a cohesive narrative about scripts, science departments, and individual classrooms. Results of the study reveal three important findings: (1) the departmental script is not an artefact, but instead is an ongoing conversation into the episteme, techne and phronesis of science teaching; (2) the consistently reformed teaching practices that were observed lead us to believe that a departmental script has the capacity to enhance the teaching of science as inquiry; and, (3) the existence of a departmental script does not mean that teaching will be `standardized' in the bureaucratic sense of the word. Our findings indicate that a departmental script can be considered to concurrently operate as an epistemic script that is translated consistently across the classes, and a social script that was more open to interpretation within individual teachers' classrooms.

Holve, Erin

2016-01-01

"Open science" includes a variety of approaches to facilitate greater access to data and the information produced by processes of scientific inquiry. Recently, the health sciences community has been grappling with the issue of potential pathways and models to achieve the goals of open science-namely, to create and rapidly share reproducible health research. eGEMs' continued dedication to and milestones regarding the publication of innovative, useful, and timely research to help contribute to the push towards open science is discussed, as well as the EDM Forum's new data sharing platform, CIELO. Although strides have been made, there is still more work to be done to help health sciences community truly embrace open science.

Coupling nonlinear optical waves to photoreactive and phase-separating soft matter: Current status and perspectives

NASA Astrophysics Data System (ADS)

Biria, Saeid; Morim, Derek R.; An Tsao, Fu; Saravanamuttu, Kalaichelvi; Hosein, Ian D.

2017-10-01

Nonlinear optics and polymer systems are distinct fields that have been studied for decades. These two fields intersect with the observation of nonlinear wave propagation in photoreactive polymer systems. This has led to studies on the nonlinear dynamics of transmitted light in polymer media, particularly for optical self-trapping and optical modulation instability. The irreversibility of polymerization leads to permanent capture of nonlinear optical patterns in the polymer structure, which is a new synthetic route to complex structured soft materials. Over time more intricate polymer systems are employed, whereby nonlinear optical dynamics can couple to nonlinear chemical dynamics, opening opportunities for self-organization. This paper discusses the work to date on nonlinear optical pattern formation processes in polymers. A brief overview of nonlinear optical phenomenon is provided to set the stage for understanding their effects. We review the accomplishments of the field on studying nonlinear waveform propagation in photopolymerizable systems, then discuss our most recent progress in coupling nonlinear optical pattern formation to polymer blends and phase separation. To this end, perspectives on future directions and areas of sustained inquiry are provided. This review highlights the significant opportunity in exploiting nonlinear optical pattern formation in soft matter for the discovery of new light-directed and light-stimulated materials phenomenon, and in turn, soft matter provides a platform by which new nonlinear optical phenomenon may be discovered.

Executive impunity and parallel justice? The United Kingdom debate on secret inquests and inquiries.

PubMed

Bray, Rebecca Scott

2012-03-01

At the beginning of 2008, the United Kingdom Government rolled into the Counter-Terrorism Bill some controversial proposals to reform coronial inquest processes, namely clauses that would provide for "secret inquests". The provisions were heavily criticised both inside and outside Parliament, and took a rocky passage through both the House of Commons and the House of Lords before eventually being abandoned by the government. In 2009 the government again tried to introduce "secret inquests" with the Coroners and Justice Bill, instead ultimately succeeding in establishing what critics have termed a "parallel" system of justice through provisions around "secret inquiries". This move has been seen as subverting the principles of transparency and open justice in the investigation of contentious deaths. This article examines the government's efforts to introduce "secret inquests" and thereafter "secret inquiries" in the context of the United Kingdom's coronial law and purpose, human rights obligations and the ongoing issues around sensitive intelligence, and examines the clash of laws that gave rise to the controversial proposals.

Inquiry-Based Science and Technology Enrichment Program for Middle School-Aged Female Students

NASA Astrophysics Data System (ADS)

Kim, Hanna

2016-04-01

This study investigates the effects of an intensive 1-week Inquiry-Based Science and Technology Enrichment Program (InSTEP) designed for middle school-aged female students. InSTEP uses a guided/open inquiry approach that is deepened and redefined as eight sciences and engineering practices in the Next Generation Science Standards, which aimed at increasing female students' interest in science and science-related careers. This study examined the effectiveness of InSTEP on 123 female students' pre-assessment and post-assessment changes in attitudes toward science and content knowledge of selected science concepts. An attitude survey, a science content test with multiple-choice questions, written assignments, and interviews to collect data were all used to measure students' attitudes and content knowledge. A within-group, repeated measure design was conducted, and the results indicated that at the post-intervention level, InSTEP increased the participants' positive attitudes toward science, science-related careers, and content knowledge of selected science concepts.

Exploring the meaning of practicing classroom inquiry from the perspectives of National Board Certified Science Teachers

NASA Astrophysics Data System (ADS)

Karaman, Ayhan

Inquiry has been one of the most prominent terms of the contemporary science education reform movement (Buck, Latta, & Leslie-Pelecky, 2007; Colburn, 2006; Settlage, 2007). Practicing classroom inquiry has maintained its central position in science education for several decades because science education reform documents promote classroom inquiry as the potential savior of science education from its current problems. Likewise, having the capabilities of teaching science through inquiry has been considered by National Board for Professional Teaching Standards [NBPTS] as one of the essential elements of being an accomplished science teacher. Successful completion of National Board Certification [NBC] assessment process involves presenting a clear evidence of enacting inquiry with students. Despite the high-profile of the word inquiry in the reform documents, the same is not true in schools (Crawford, 2007). Most of the science teachers do not embrace this type of approach in their everyday teaching practices of science (Johnson, 2006; Luera, Moyer, & Everett, 2005; Smolleck, Zembal-Saul, & Yoder, 2006; Trumbull, Scarano, & Bonney, 2006). And the specific meanings attributed to inquiry by science teachers do not necessarily match with the original intentions of science education reform documents (Matson & Parsons, 2006; Wheeler, 2000; Windschitl, 2003). Unveiling the various meanings held by science teachers is important in developing better strategies for the future success of science education reform efforts (Jones & Eick, 2007; Keys & Bryan, 2001). Due to the potential influences of National Board Certified Science Teachers [NBCSTs] on inexperienced science teachers as their mentors, examining inquiry conceptions of NBCSTs is called for. How do these accomplished practitioners understand and enact inquiry? The purpose of this dissertation research study was twofold. First, it investigated the role of NBC performance assessment process on the professional development of science teachers. Second, it examined the meaning of practicing classroom inquiry for National Board Certified Science Teachers [NBCSTs]. Based on the specific cases of four NBCSTs, this naturalistic inquiry study was conducted to answer to those questions with the involvement of the following qualitative data sources: classroom observations, in-depth teacher interviews, and document analyses of teacher portfolios. The specific cases in this study indicated that undergoing the performance assessment process of NBC played an affirmational role for National Board Certified Science Teachers [NBCSTs] in their professional development. Their successful completion of the portfolio assessment process created a sharpened confidence into their existing notions and ways of teaching science. In the study, not all teachers were equally open to science education reform ideas. This meant that NBC experience strengthened the conventional notions of teaching science held by some teachers rather than generating a higher affiliation with the reform ideas. The teacher cases presented in this study denoted that teachers' conceptions of classroom inquiry were driven both by scientific and constructivist rationales. However, NBCSTs failed to create broader operational definitions of classroom inquiry. They tended to reduce the meaning of classroom inquiry into empirical investigations of students. The conventional representation of the scientific method as a stepwise linear process influenced teachers' understandings and practices of classroom inquiry. NBCSTs used inquiry in their classrooms to introduce their students to the cognitive processes and the actions of practicing scientists but not necessarily to teach scientific principles. Their reluctance to teach scientific principles through inquiry developed in parallel to their tendency of associating classroom inquiry with the highest levels of student autonomy. Participant teachers' particular understandings of scientific literacy produced a tension between embracing inquiry more in their teaching practices of science and educating scientifically literate students. The teachers in the study attributed the hurdles that kept them from using more inquiry with their students to external factors. In the final chapter of the dissertation study, these findings were discussed in connection with the education literature.

Computer-based outbreak and disease surveillance requires high-quality software that is well-supported and affordable. Developing software in an open-source framework, which entails free distribution and use of software and continuous, community-based software development, can produce software with such characteristics, and can do so rapidly. The objective of the Real-Time Outbreak and Disease Surveillance (RODS) Open Source Project is to accelerate the deployment of computer-based outbreak and disease surveillance systems by writing software and catalyzing the formation of a community of users, developers, consultants, and scientists who support its use. The University of Pittsburgh seeded the Open Source Project by releasing the RODS software under the GNU General Public License. An infrastructure was created, consisting of a website, mailing lists for developers and users, designated software developers, and shared code-development tools. These resources are intended to encourage growth of the Open Source Project community. Progress is measured by assessing website usage, number of software downloads, number of inquiries, number of system deployments, and number of new features or modules added to the code base. During September--November 2003, users generated 5,370 page views of the project website, 59 software downloads, 20 inquiries, one new deployment, and addition of four features. Thus far, health departments and companies have been more interested in using the software as is than in customizing or developing new features. The RODS laboratory anticipates that after initial installation has been completed, health departments and companies will begin to customize the software and contribute their enhancements to the public code base.

The prevalence and detrimental health effects of intimate partner violence have resulted in international discussions and recommendations that health care professionals should screen women for intimate partner violence during general and antenatal health care visits. Due to the lack of discussion on routine or case-based inquiry for intimate partner violence during antenatal care in Germany, this study seeks to explore its acceptability among pregnant German women. A mixed methods approach was used, utilizing a self-administered survey on the acceptability of routine or case-based inquiry for intimate partner violence in a university hospital's maternity ward in Munich and in-depth interviews with seven women who experienced violence during pregnancy. Of the 401 women who participated in the survey, 92 percent were in favor of routine or case-based inquiry for intimate partner violence during antenatal care. Acceptance of routine or case-based inquiry for intimate partner violence during antenatal care was significantly associated with women's experiences of child sexual abuse, being young, less educated, single or divorced and smoking during pregnancy. Open-ended survey questions and in-depth interviews stressed adequate training for screening, sufficient time and provision of referral information as important conditions for routine or case-based inquiry for intimate partner violence. Women in this study showed an overwhelming support for routine or case-based screening for intimate partner violence in antenatal care in Germany. Until adequate training is in place to allow providers to inquire for intimate partner violence in a professional manner, this study recommends that health care providers are made aware of the prevalence and health consequences of violence during pregnancy.

Organizational Behavior and Human Decision Processes, 50, 248-287. doi:10.1016/0749-5978(91)90022-L] accords high importance to the mechanisms of human agency and how they are exercised through self-efficacy. In this paper, we developed and validated the McGill Self-Efficacy For Inquiry Engagement (McSELFIE) instrument with undergraduate students in natural science disciplines. We defined inquiry engagement as carrying out the practices of science (POS) that are supported by students' personality characteristics (SPCs) and that result in achieving inquiry-learning outcomes (ILOs). Based on these theoretical perspectives, the McSELFIE is a 60-item, learner-focused survey that addresses three components that are theoretically important for engaging in scientific inquiry: (a) SPCs, (b) ILOs, and (c) POS. Evidence for construct and content validity were obtained by using experts' judgments and confirmatory factor analysis with a sample of 110 undergraduate students enrolled in science disciplines. Internal consistency of the factors and instrument was also examined. The McSELFIE instrument is a reliable and valid instrument for measuring science undergraduate students' self-efficacy for inquiry engagement. Matched pairs analyses were conducted among the instruments' factors. Students reported the highest self-efficacy for openness, applying knowledge, and carrying out investigations. Students reported the lowest self-efficacy for extraversion, understanding metacognitive knowledge, and planning investigations. Theoretical and practical implications are discussed.

Student's social interaction in inquiry-based science education: how experiences of flow can increase motivation and achievement

NASA Astrophysics Data System (ADS)

Ellwood, Robin; Abrams, Eleanor

2017-02-01

This research investigated how student social interactions within two approaches to an inquiry-based science curriculum could be related to student motivation and achievement outcomes. This qualitative case study consisted of two cases, Off-Campus and On-Campus, and used ethnographic techniques of participant observation. Research participants included eight eighth grade girls, aged 13-14 years old. Data sources included formal and informal participant interviews, participant journal reflections, curriculum artifacts including quizzes, worksheets, and student-generated research posters, digital video and audio recordings, photographs, and researcher field notes. Data were transcribed verbatim and coded, then collapsed into emergent themes using NVIVO 9. The results of this research illustrate how setting conditions that promote focused concentration and communicative interactions can be positively related to student motivation and achievement outcomes in inquiry-based science. Participants in the Off-Campus case experienced more frequent states of focused concentration and out performed their peers in the On-Campus case on 46 % of classroom assignments. Off-Campus participants also designed and implemented a more cognitively complex research project, provided more in-depth analyses of their research results, and expanded their perceptions of what it means to act like a scientist to a greater extent than participants in the On-Campus case. These results can be understood in relation to Flow Theory. Student interactions that promoted the criteria necessary for initiating flow, which included having clearly defined goals, receiving immediate feedback, and maintaining a balance between challenges and skills, fostered enhanced student motivation and achievement outcomes. Implications for science teaching and future research include shifting the current focus in inquiry-based science from a continuum that progresses from teacher-directed to open inquiry experiences to a continuum that also deliberately includes and promotes the necessary criteria for establishing flow. Attending to Flow Theory and incorporating student experiences with flow into inquiry-based science lessons will enhance student motivation and achievement outcomes in science and bolster the success of inquiry-based science.

Preservice science teachers' experiences with repeated, guided inquiry

NASA Astrophysics Data System (ADS)

Slack, Amy B.

The purpose of this study was to examine preservice science teachers' experiences with repeated scientific inquiry (SI) activities. The National Science Education Standards (National Research Council, 1996) stress students should understand and possess the abilities to do SI. For students to meet these standards, science teachers must understand and be able to perform SI; however, previous research demonstrated that many teachers have naive understandings in this area. Teacher preparation programs provide an opportunity to facilitate the development of inquiry understandings and abilities. In this study, preservice science teachers had experiences with two inquiry activities that were repeated three times each. The research questions for this study were (a) How do preservice science teachers' describe their experiences with repeated, guided inquiry activities? (b) What are preservice science teachers' understandings and abilities of SI? This study was conducted at a large, urban university in the southeastern United States. The 5 participants had bachelor's degrees in science and were enrolled in a graduate science education methods course. The researcher was one of the course instructors but did not lead the activities. Case study methodology was used. Data was collected from a demographic survey, an open-ended questionnaire with follow-up interviews, the researcher's observations, participants' lab notes, personal interviews, and participants' journals. Data were coded and analyzed through chronological data matrices to identify patterns in participants' experiences. The five domains identified in this study were understandings of SI, abilities to conduct SI, personal feelings about the experience, science content knowledge, and classroom implications. Through analysis of themes identified within each domain, the four conclusions made about these preservice teachers' experiences with SI were that the experience increased their abilities to conduct inquiry, increased their understanding of how they might use SI in their classroom, increased their understanding of why variables are used in experiments, and did not increase their physics content knowledge. These conclusions suggest that preservice science teachers having repeated, guided experiences with inquiry increase their abilities to conduct SI and consider how inquiry could be used in their future science classrooms.

Supporting Collective Inquiry: A Technology Framework for Distributed Learning

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 making timely and effective use of the community's knowledge base, towards producing solutions to sophisticated, ill defined problems in the domain of physics. Video analysis examined whether S3 supported teacher orchestration, freeing him to focus less on classroom management and more on students' inquiry. Three important outcomes of this research are a set of design principles for DTEL environments, a specific technology infrastructure (S3), and a DTEL research framework.

Influence of an extensive inquiry-based field experience on pre-service elementary student teachers' science teaching beliefs

NASA Astrophysics Data System (ADS)

Bhattacharyya, Sumita

This study examined the effects of an extensive inquiry-based field experience on pre-service elementary teachers' personal agency beliefs (PAB) about teaching science and their ability to effectively implement science instruction. The research combined quantitative and qualitative approaches within an ethnographic research tradition. A comparison was made between the pre and posttest scores for two groups. The experimental group utilized the inquiry method; the control group did not. The experimental group had the stronger PAB pattern. The field experience caused no significant differences to the context beliefs of either groups, but did to the capability beliefs. The number of college science courses taken by pre-service elementary teachers' was positively related to their post capability belief (p = .0209). Qualitative information was collected through case studies which included observation of classrooms, assessment of lesson plans and open-ended, extended interviews of the participants about their beliefs in their teaching abilities (efficacy beliefs), and in teaching environments (context beliefs). The interview data were analyzed by the analytic induction method to look for themes. The emerging themes were then grouped under several attributes. Following a review of the attributes a number of hypotheses were formulated. Each hypothesis was then tested across all the cases by the constant comparative method. The pattern of relationship that emerged from the hypotheses testing clearly suggests a new hypothesis that there is a spiral relationship among the ability to establish communicative relationship with students, desire for personal growth and improvement, and greater content knowledge. The study concluded that inquiry based student teaching should be encouraged to train school science teachers. But the meaning and the practice of the inquiry method should be clearly delineated to ensure its correct implementation in the classroom. A survey should be undertaken to ascertain the extent to which what is currently being practiced, as the inquiry method is indeed the inquiry method. Practicing the inquiry method is greatly more demanding than traditional methods of teacher training. A widespread adoption of the method will require considerable changes in these factors.

Re-conceptualizing the nursing metaparadigm: Articulating the philosophical ontology of the nursing discipline that orients inquiry and practice.

PubMed

Bender, Miriam

2018-04-10

Jacqueline Fawcett's nursing metaparadigm-the domains of person, health, environment, and nursing-remains popular in nursing curricula, despite having been repeatedly challenged as a logical philosophy of nursing. Fawcett appropriated the word "metaparadigm" (indirectly) from Margaret Masterman and Thomas Kuhn as a devise that allowed her to organize then-current areas of nursing interest into a philosophical "hierarchy of knowledge," and thereby claim nursing inquiry and practice as rigorously "scientific." Scholars have consistently rejected the logic of Fawcett's metaparadigm, but have not yet proposed a substantially agreed-upon alternative. Through an analysis of articles introducing and critiquing Fawcett's metaparadigm, I argue for a re-conceptualized metaparadigm that articulates nursing's ontology. What exists for the nursing discipline are not already-demarcated metaparadigm domains, but rather interdependent, dynamic relations that constitute people, including nurses, in their health/environment circumstance. The nursing discipline aims to skillfully access this dynamic relationality as the basis for action and reflection to produce both positive health trajectories and knowledge that facilitates future action and reflection. Further inquiry into the onto-epistemology of nursing will produce a more robust understanding of nursing practice, science, and philosophy, and clarify its unique contribution to health and healthcare. © 2018 John Wiley & Sons Ltd.

We transformed our first-year curriculum in biology with a new course, Biological Inquiry, in which >50% of all incoming, first-year students enroll. The course replaced a traditional, content-driven course that relied on outdated approaches to teaching and learning. We diversified pedagogical practices by adopting guided inquiry in class and in labs, which are devoted to building authentic research skills through open-ended experiments. Students develop core biological knowledge, from the ecosystem to molecular level, and core skills through regular practice in hypothesis testing, reading primary literature, analyzing data, interpreting results, writing in disciplinary style, and working in teams. Assignments and exams require higher-order cognitive processes, and students build new knowledge and skills through investigation of real-world problems (e.g., malaria), which engages students' interest. Evidence from direct and indirect assessment has guided continuous course revision and has revealed that compared with the course it replaced, Biological Inquiry produces significant learning gains in all targeted areas. It also retains 94% of students (both BA and BS track) compared with 79% in the majors-only course it replaced. The project has had broad impact across the entire college and reflects the input of numerous constituencies and close collaboration among biology professors and students.

Playing With Antidepressants: Perspectives From Indian Australians and Anglo-Australians Living With Depression.

PubMed

Brijnath, Bianca; Antoniades, Josefine

2017-11-01

Patient perspectives were explored on the meaning and experience of antidepressant use by applying Johan Huizinga's theory of play to interviews from Indian Australians and Anglo-Australians diagnosed with depression. Through the analysis, the centrality of Huizinga's "magic circle" emerged, that is, defining the boundaries within which one could safely play. Consumption of antidepressants involved learning, breaking, and modulating rules of the game of adherence, then forging a new "magic circle." In these games, there were playful elements including experimentation, improvisation, absorption, and experiential learning. This application of Huizinga's theory in relation to antidepressant use is a novel approach in the literature on medication non/adherence. This application not only opens a new theoretical line of inquiry but also shows that antidepressant non/adherence is not a static practice but dynamic and changing, revealing critical insights around participant's agency, capabilities, desires, and notions of selfhood with regard to managing their depression and conceptualizing their recovery.

A fundamental challenge in immunology is to decipher the principles governing immune responses at the whole-organism scale. Here, using a comparative infection model, we observe immune signal propagation within and between organs to obtain a dynamic map of immune processes at the organism level. We uncover two inter-organ mechanisms of protective immunity mediated by soluble and cellular factors. First, analyzing ligand-receptor connectivity across tissues reveals that type I IFNs trigger a whole-body antiviral state, protecting the host within hours after skin vaccination. Second, combining parabiosis, single-cell analyses, and gene knockouts, we uncover a multi-organ web of tissue-resident memory T cells that functionally adapt to their environment to stop viral spread across the organism. These results have implications for manipulating tissue-resident memory T cells through vaccination and open up new lines of inquiry for the analysis of immune responses at the organism level.

Parker, S. J.; Slater, T. F.; Shipp, S.; Lowes, L.

2007-12-01

Science education reform documents universally call for students to have authentic experiences using real data in the context of their science education that mimic actual research. In order for planetary scientists to provide the most useful data or professional development for K-12 teachers, a survey was undertaken to determine how teachers are currently using planetary science data and, if not, why not. A national survey collected data from 320 teachers from 42 states. Teachers targeted for this survey were those who are most likely to be knowledgeable in the ins and outs of using online planetary data. When asked to identify the ESS online resources that they access five or more days per year the three more commonly used websites were USGS.gov (28%), GoogleEarth (23%), and Volcano World (12%). However, at this time, the use of online data for inquiry and analysis in the classroom is actually quite rare. Survey results indicate that 41-24% of teachers use student collected data and teacher- produced hard copies of data for the bulk of any inquiry or analysis that is conducted in class. Most often (52%) teachers' primary use of the internet in ESS involves the downloading of images to share with students. Only 25- 32% of these teachers report that they use online data, in the forms of large WWW data sets real time data, or virtual online data, to engage students in inquiry or data analysis. The most noteworthy finding is that 89% of teachers report that they rarely use the most open and authentic forms of inquiry when instructing students. Data shows that the types of inquiry always or usually used by teachers are confirmation activities (38%) or structured inquiry (46%), in which students investigate the teacher-provided question, using a prescribed procedure. 81% of ESS teachers stated that the amount of time allocated to inquiry in their classrooms is either not enough, or wholly insufficient. Teachers did not perceive that inquiry increases students' assessment scores on state tests. When questioned about barriers to using inquiry in the classroom, 51% of respondents stated that the number of topics covered by state assessments is a great or immense barrier as is the perceived amount of time required to inquire using real data.

Analysis of the project synthesis goal cluster orientation and inquiry emphasis of elementary science textbooks

NASA Astrophysics Data System (ADS)

Staver, John R.; Bay, Mary

The purpose of this descriptive study was to examine selected units of commonly used elementary science texts, using the Project Synthesis goal clusters as a framework for part of the examination. An inquiry classification scheme was used for the remaining segment. Four questions were answered: (1) To what extent do elementary science textbooks focus on each Project Synthesis goal cluster? (2) In which part of the text is such information found? (3) To what extent are the activities and experiments merely verifications of information already introduced in the text? (4) If inquiry is present in an activity, then what is the level of such inquiry?Eleven science textbook series, which comprise approximately 90 percent of the national market, were selected for analysis. Two units, one primary (K-3) and one intermediate (4-6), were selected for analysis by first identifying units common to most series, then randomly selecting one primary and one intermediate unit for analysis.Each randomly selected unit was carefully read, using the sentence as the unit of analysis. Each declarative and interrogative sentence in the body of the text was classified as: (1) academic; (2) personal; (3) career; or (4) societal in its focus. Each illustration, except those used in evaluation items, was similarly classified. Each activity/experiment and each miscellaneous sentence in end-of-chapter segments labelled review, summary, evaluation, etc., were similarly classified. Finally, each activity/experiment, as a whole, was categorized according to a four-category inquiry scheme (confirmation, structured inquiry, guided inquiry, open inquiry).In general, results of the analysis are: (1) most text prose focuses on academic science; (2) most remaining text prose focuses on the personal goal cluster; (3) the career and societal goal clusters receive only minor attention; (4) text illustrations exhibit a pattern similar to text prose; (5) text activities/experiments are academic in orientation, almost to the exclusion of other goal clusters; (6) end-of-chapter sentences are largely academic; (7) inquiry is absent or present only in limited forms in text activities/experiments; and (8) texts allocate only a minor portion of space to activities/experiments. Detailed findings are given as numeral, percentage, and decimal values. Discussion focuses on the implications of the results and a comparison of NSTA recommendations with the results of this analysis.

Science teachers' attempts at integrating feminist pedagogy through collaborative action research

Capobianco, Brenda M.

2007-01-01

The purpose of this study was to examine the experiences of three science teachers attempting to transform their practice by conducting action research on feminist science teaching. The teachers engaged in systematic, self-critical inquiry of their own practice and joined 8 other science teachers to engage in collaborative conversations about the nature of science, science teaching, and science education as a way of coming to a better understanding of how science can be taught for a more diverse group of students. Data were gathered via semistructured interviews, whole-group discussions, classroom observations, and review of supporting documents. Data analysis was based on narrative inquiry, where particular attention was given to the construction and reconstruction of the teachers' stories of their practical inquiries. Results indicated that the teachers as researchers of their own practice gained new knowledge about feminist science teaching and, furthermore, generated a cluster of pedagogical possibilities for inclusive, dynamic science teaching.

The ethics of conducting a co-operative inquiry with vulnerable people.

PubMed

Tee, Stephen R; Lathlean, Judith A

2004-09-01

Mental health services users have been calling for greater participation in clinical research. Participation in this context means research 'with' rather than 'on' groups of people. Conducting a co-operative inquiry involving the participation of vulnerable individuals as co-researchers, in particular those with a history of mental health problems, places an obligation on researchers to articulate and justify sound ethical procedures. The aim of this paper is to consider how the ethical issues encountered when conducting participative research with vulnerable people can be addressed in the implementation of a co-operative inquiry with users of mental health services. The study was based on personal reflection and a critical review of associated literature obtained from a database search using Boolean logic. The findings, presented under the headings of the four prima facie moral principles, suggest the need for researchers using participative approaches to demonstrate the humanistic attributes required for engaging and working with people over a period of time. These include building and maintaining trusting relationships, assessing competence to participate, managing interpersonal and group dynamics and making complex collaborative decisions about participants' continued participation in a study. When using a co-operative inquiry approach involving vulnerable individuals, researchers need to demonstrate clearly how a balance between autonomy and paternalism will be achieved, how risks will be anticipated and managed and how fairness will be maintained throughout all procedures. Researchers using participative approaches need to have developed a level of personal insight and self-awareness through access to supervision which focuses on sources of unintended manipulation and interpersonal dynamics that may arise at the inception of a study and throughout its course. Researchers and ethics committees have a shared responsibility to ensure that vulnerable people are appropriately engaged to maintain the advancement of user knowledge which informs nursing practice.

Inquiring minds: Case studies of two middle school science teachers as they include inquiry and graphing in their curricula

NASA Astrophysics Data System (ADS)

Scarano, Grace Hotchkiss

2000-10-01

Current reform documents in science and mathematics call for teachers to include inquiry and data analysis in their teaching. This interpretive quasi-ethnographic case study examined two middle school science teachers as they planned and implemented inquiry and graphing in their science curricula. The focus question for this research was: What are middle school science teachers' experiences as they include graphing and inquiry-based student research projects in their curricula? How is teaching these areas different from usual teaching? The research examined two teachers teaching their favorite unit, parts of other familiar units, graphing, and student inquiry. Four main types of data were gathered: (1) observations of teachers' instruction, (2) interviews and meetings with the teachers, (3) curricular artifacts, and (4) questionnaires and other written material. The study took place over a seven-month period. The findings revealed that these two teachers had different ideologies of schooling and that these ideologies shaped the teachers' planning and implementation of their usual content as well as graphing and inquiry. One teacher's ideology was technical, and the other's was constructive. Six themes emerged as salient features of their teaching: (1) the role of developing a vision for curricular implementation, (2) curricular decisions: internal and external authority, (3) views of knowing and learning, (4) perceptions of the nature of science, (5) attending to a personal concern in teaching, and (6) reflection. The textures of these themes varied between the two teachers, and formed a coherent yet dynamic system within which each teacher maneuvered. This study found that both teachers found it challenging to include inquiry in their curricula, even though both had attended workshops designed to help teachers use student inquiry. The constructive teacher's implementation was more in line with the notions that are central to constructivism and current non-traditional views of the nature of science than was that of the technical teacher. The teacher with a technical ideology relied on the scientific method to organize student projects and implemented inquiry as a technique to increase student-centered work. It is proposed that teachers with technical ideologies need to undergo an ideological shift toward constructive ideologies of schooling in order to teach graphing and inquiry in ways that are aligned with current reform efforts.

Interactive software tool to comprehend the calculation of optimal sequence alignments with dynamic programming.

PubMed

Ibarra, Ignacio L; Melo, Francisco

2010-07-01

Dynamic programming (DP) is a general optimization strategy that is successfully used across various disciplines of science. In bioinformatics, it is widely applied in calculating the optimal alignment between pairs of protein or DNA sequences. These alignments form the basis of new, verifiable biological hypothesis. Despite its importance, there are no interactive tools available for training and education on understanding the DP algorithm. Here, we introduce an interactive computer application with a graphical interface, for the purpose of educating students about DP. The program displays the DP scoring matrix and the resulting optimal alignment(s), while allowing the user to modify key parameters such as the values in the similarity matrix, the sequence alignment algorithm version and the gap opening/extension penalties. We hope that this software will be useful to teachers and students of bioinformatics courses, as well as researchers who implement the DP algorithm for diverse applications. The software is freely available at: http:/melolab.org/sat. The software is written in the Java computer language, thus it runs on all major platforms and operating systems including Windows, Mac OS X and LINUX. All inquiries or comments about this software should be directed to Francisco Melo at fmelo@bio.puc.cl.

Imagining tomorrow's university in an era of open science.

Howe, Adina; Howe, Michael; Kaleita, Amy L; Raman, D Raj

2017-01-01

As part of a recent workshop entitled "Imagining Tomorrow's University", we were asked to visualize the future of universities as research becomes increasingly data- and computation-driven, and identify a set of principles characterizing pertinent opportunities and obstacles presented by this shift. In order to establish a holistic view, we take a multilevel approach and examine the impact of open science on individual scholars and how this impacts as well as on the university as a whole. At the university level, open science presents a double-edged sword: when well executed, open science can accelerate the rate of scientific inquiry across the institution and beyond; however, haphazard or half-hearted efforts are likely to squander valuable resources, diminish university productivity and prestige, and potentially do more harm than good. We present our perspective on the role of open science at the university.

Teacher students' dilemmas when teaching science through inquiry

NASA Astrophysics Data System (ADS)

Krämer, Philipp; Nessler, Stefan H.; Schlüter, Kirsten

2015-09-01

Background: Inquiry-based science education (IBSE) is suitable to teach scientific contents as well as to foster scientific skills. Similar conclusions are drawn by studies with respect to scientific literacy, motivational aspects, vocabulary knowledge, conceptual understandings, critical thinking, and attitudes toward science. Nevertheless, IBSE is rarely adopted in schools. Often barriers for teachers account for this lack, with the result that even good teachers struggle to teach science as inquiry. More importantly, studies indicate that several barriers and constraints could be ascribed to problems teacher students have at the university stage. Purpose: The purpose of this explorative investigation is to examine the problems teacher students have when teaching science through inquiry. In order to draw a holistic picture of these problems, we identified problems from three different points of view leading to the research question: What problems regarding IBSE do teacher students have from an objective, a subjective, and a self-reflective perspective? Design & method: Using video analysis and observation tools as well as qualitative content analysis and open questionnaires we identified problems from each perspective. Results: The objectively stated problems comprise the lack of essential features of IBSE especially concerning 'Supporting pupils' own investigations' and 'Guiding analysis and conclusions.' The subjectively perceived problems comprise concerns about 'Teachers' abilities' and 'Pupils' abilities,' 'Differentiated instruction' and institutional frame 'Conditions' while the self-reflectively noticed problems mainly comprise concerns about 'Allowing inquiry,' 'Instructional Aspects,' and 'Pupils' behavior.' Conclusions: Each of the three different perspectives provides plenty of problems, partially overlapping, partially complementing one another, and partially revealing completely new problems. Consequently, teacher educators have to consider these three perspectives.

Lonergan's philosophy as grounding for cross-disciplinary research.

PubMed

Kane, Anne

2014-04-01

Increasingly, nurses conduct scientific inquiry into complex health-care problems by collaborating on teams with researchers from other highly specialized fields. As cross-disciplinary research proliferates and becomes institutionalized globally, researchers will increasingly encounter the need to integrate their particular research perspectives within inquiries without sacrificing the potential contributions of their discipline-specific expertise. The work of the philosopher Bernard Lonergan (1904–1984) offers the necessary philosophical grounding. Here, I defend a role for philosophy in cross-disciplinary research and present selected ideas in Lonergan's work. These include: (1) a dynamic, normative pattern that each inquirer operates uniquely also forms the common core, or unity, in knowing; (2) the possibility of cross-disciplinary knowledge development is dependent on each researcher's consciousness of her or his attentiveness, intelligence, reasonableness, and responsibleness; and (3) shifts in researchers' viewpoints, or horizons, facilitate their collaborative inquiry and their grasp of the unity in knowing. The desire to know, shared by team members, drives their inquiry. Lonergan's stance is consistent with nursing values because it respects, but does not unconditionally privilege, any researcher or discipline. Arguments support a claim that Lonergan's perspective is well suited to guide nurse researchers participating on cross-disciplinary health research teams.

Facilitating Tough Conversations: Using an Innovative Simulation-Primed Qualitative Inquiry in Pediatric Research.

PubMed

Wong, Ambrose H; Tiyyagura, Gunjan K; Dodington, James M; Hawkins, Bonnie; Hersey, Denise; Auerbach, Marc A

Deep exploration of a complex health care issue in pediatrics might be hindered by the sensitive or infrequent nature of a particular topic in pediatrics. Health care simulation builds on constructivist theories to guide individuals through an experiential cycle of action, self-reflection, and open discussion, but has traditionally been applied to the educational domain in health sciences. Leveraging the emotional activation of a simulated experience, investigators can prime participants to engage in open dialogue for the purposes of qualitative research. The framework of simulation-primed qualitative inquiry consists of 3 main iterative steps. First, researchers determine applicability by consideration of the need for an exploratory approach and potential to enrich data through simulation priming of participants. Next, careful attention is needed to design the simulation, with consideration of medium, technology, theoretical frameworks, and quality to create simulated reality relevant to the research question. Finally, data collection planning consists of a qualitative approach and method selection, with particular attention paid to psychological safety of subjects participating in the simulation. A literature review revealed 37 articles that used this newly described method across a variety of clinical and educational research topics and used a spectrum of simulation modalities and qualitative methods. Although some potential limitations and pitfalls might exist with regard to resources, fidelity, and psychological safety under the auspices of educational research, simulation-primed qualitative inquiry can be a powerful technique to explore difficult topics when subjects might experience vulnerability or hesitation.

This article presents the results of a qualitative study aimed at determining the effectiveness of the camera obscura as a didactic tool to understand image formation (i.e., how it is possible to see objects and how their image is formed on the retina, and what the image formed on the retina is like compared to the object observed) in a context of scientific inquiry. The study involved 104 prospective primary teachers (PPTs) who were being trained in science teaching. To assess the effectiveness of this tool, an open questionnaire was applied before (pre-test) and after (post-test) the educational intervention. The data were analyzed by combining methods of inter- and intra-rater analysis. The results showed that more than half of the PPTs advanced in their ideas towards the desirable level of knowledge in relation to the phenomena studied. The conclusion reached is that the camera obscura, used in a context of scientific inquiry, is a useful tool for PPTs to improve their knowledge about image formation and experience in the first person an authentic scientific inquiry during their teacher training.

often closed-ended. The outcomes are known in advance and students replicate procedures recommended by the teacher. Over the years, I have come to appreciate the great opportunities created by allowing students investigative freedom in physics laboratories. I have realized that a laboratory environment in which students are free to conduct investigations using procedures of their own design can provide them with varied and rich opportunities for discovery. This paper describes what open-ended laboratory investigations have added to my high school physics classes. I will provide several examples of open-ended laboratories and discuss the benefits they conferred on students and teacher alike.

2018-01-01

International studies of science education, such as the Trends in Mathematics and Science Study (TIMSS), have revealed considerable national disparities in students' achievements in science education. The results have prompted many nations to compare their science education systems and practices to those of others, to gain insights for improvement. Teacher training and professional development are key educational components that have not attracted as much attention as they deserve in international comparative studies. This study compares the conceptions and attitudes of pre-service elementary teachers (PSETs) in Hong Kong and the United States with respect to inquiry science learning and teaching at the beginning of the semester before the start of the science methods course. PSETs' conceptions and attitudes in the two countries were compared by means of a questionnaire with both Likert-type and open-ended questions. Quantitative data were analyzed using exploratory factor analysis and inferential statistics, while qualitative data were analyzed through the systematic categorization of PSETs' responses into broad themes and subthemes to reflect patterns in their conceptions of and attitudes toward inquiry science learning and teaching. The results revealed a complex interplay between PSETs' conceptions of and attitudes toward inquiry science learning and teaching. The results shed light on the effects of sociocultural contexts and have important implications for the design of science methods courses.

Exploring the complexity of inquiry learning in an open-ended problem space

NASA Astrophysics Data System (ADS)

Clarke, Jody

Data-gathering and problem identification are key components of scientific inquiry. However, few researchers have studied how students learn these skills because historically this required a time-consuming, complicated method of capturing the details of learners' data-gathering processes. Nor are classroom settings authentic contexts in which students could exhibit problem identification skills parallel to those involved in deconstructing complex real world situations. In this study of middle school students, because of my access to an innovative technology, I simulated a disease outbreak in a virtual community as a complicated, authentic problem. As students worked through the curriculum in the virtual world, their time-stamped actions were stored by the computer in event-logs. Using these records, I tracked in detail how the student scientists made sense of the complexity they faced and how they identified and investigated the problem using science-inquiry skills. To describe the degree to which students' data collection narrowed and focused on a specific disease over time, I developed a rubric and automated the coding of records in the event-logs. I measured the ongoing development of the students' "systematicity" in investigating the disease outbreak. I demonstrated that coding event-logs is an effective yet non-intrusive way of collecting and parsing detailed information about students' behaviors in real time in an authentic setting. My principal research question was "Do students who are more thoughtful about their inquiry prior to entry into the curriculum demonstrate increased systematicity in their inquiry behavior during the experience, by narrowing the focus of their data-gathering more rapidly than students who enter with lower levels of thoughtfulness about inquiry?" My sample consisted of 403 middle-school students from public schools in the US who volunteered to participate in the River City Project in spring 2008. Contrary to my hypothesis, I found that prior thoughtfulness of inquiry was not a predictor of the subsequent development of systematicity. However, all students did indeed become more systematic in their scientific behavior over time. On average, boys were generally more systematic than girls, but the rates at which systematicity increased with time was identical across the genders.

Achieving a coherent curriculum in second grade: Science as the organizer

NASA Astrophysics Data System (ADS)

Park Rogers, Meredith A.

The purpose of this study was to examine how a team of four second grade teachers used their approach to teaching science as a means for designing and implementing a coherent curriculum. Within this study, curriculum coherency refers to making logical instructional connections that are both visible and explicit for students. A teacher using a common teaching strategy or critical thinking skills in such a way that the commonalities between subject areas are clearly demonstrated to students is one example of curriculum coherency. The research framework guiding this study was phenomenology; I used a case study method for data analysis. The primary data source was field notes gathered during 10 weeks of classroom observations. Secondary data sources included observations of team meetings, two sets of interviews with each of the four teachers, an interview with the school principal, and artifacts used and developed by the teachers. An analysis of the data led me to interpret the following findings: (1) the teachers viewed science as a tool to motivate their students to learn and believed in teaching science through an inquiry-based approach; (2) they described science inquiry as a process of thinking organized around questions, and saw their teaching role as shifting between guided and open classroom inquiry; (3) they taught all subjects using an inquiry-based approach, emphasized the process skills associated with doing scientific inquiry, and consistently used the language of the process skills throughout their instruction of all disciplines; (4) their team's collaborative approach played a significant role in achieving their vision of a coherent curriculum; the successfulness of their collaboration relied on the unique contributions of each member and her commitment to professional development. This study demonstrates how an inquiry-based science curriculum can provide educators with an effective model for designing and implementing a coherent curriculum. Furthermore, the findings have implications for elementary preservice and inservice programs with respect to using science teaching as a foundation for developing curriculum coherency.

Construction of technological artifacts and teaching strategies to promote flexible scientific understanding

NASA Astrophysics Data System (ADS)

Spitulnik, Michele Wisnudel

Science education reforms advocate inquiry as a way to build explanations and make informed decisions. Based on this call this dissertation (1) defines flexible scientific understanding by elaborating on content, inquiry and epistemic understandings; (2) describes an inquiry based unit that integrates dynamic modeling software; (3) examines students' understandings as they construct models; and (4) identifies instructional strategies that support inquiry and model building. A curriculum unit was designed to engage students in inquiry by identifying problems and constructing models to represent, explain and predict phenomena. Ninth grade students in a public mid-western high school worked in teams of 2-3 to ask questions, find information and reflect on the purposes of models. Data sources including classroom video, observations, interviews, student models and handouts were used to formulate cases that examine how two groups construct understanding. A teacher case study identifies the teaching strategies that support understanding. Categories within content, inquiry and epistemic understandings were used to analyze student understandings and teaching supports. The findings demonstrate that students can build flexible understanding by constructing models. Students built: (1) content understanding by identifying key ideas and building relationships and explanations of phenomena; (2) inquiry understanding by defining problems, constructing models and developing positions; and (3) epistemic understanding by describing the purposes of models as generalizing phenomena, testing hypotheses and making predictions. However, students demonstrated difficulty in using evidence to defend scientific arguments. Strategies that support flexible understanding were also identified. Content supports include: setting expectations for explanations; using examples to illustrate explanations; modeling questions; and providing feedback that prompts detailed explanations. Supports for inquiry are setting expectations for data gathering; using examples that illustrate model building; modeling the development of an argument; and providing feedback to promote coherent models. Epistemic supports include: using examples to illustrate purposes and assumptions within models, and providing feedback as students evaluate their models. The dissertation demonstrates that teaching strategies impact student understanding but are challenging to implement. When strategies are not used, students do not necessarily construct desired outcomes such as, using evidence to support arguments.

Technology has been widely involved in science research. Researchers are now applying it to science education in an attempt to bring students’ science activities closer to authentic science activities. The present study synthesizes the research to discuss the development of technology-enhanced laboratories and how technology may contribute to fulfilling the instructional objectives of laboratories in physics. To be more specific, this paper discusses the engagement of technology to innovate physics laboratories and the potential of technology to promote inquiry, instructor and peer interaction, and learning outcomes. We then construct a framework for teachers, scientists, and programmers to guide and evaluate technology-integrated laboratories. The framework includes inquiry learning and openness supported by technology, ways of conducting laboratories, and the diverse learning objectives on which a technology-integrated laboratory may be focused.

2016-04-01

Current trends in health care research point to a shift from disciplinary models to interdisciplinary team-based mixed methods inquiry designs. This keynote address discusses the problems and prospects of creating vibrant mixed methods health care interdisciplinary research teams that can harness their potential synergy that holds the promise of addressing complex health care issues. We examine the range of factors and issues these types of research teams need to consider to facilitate efficient interdisciplinary mixed methods team-based research. It is argued that concepts such as disciplinary comfort zones, a lack of attention to team dynamics, and low levels of reflexivity among interdisciplinary team members can inhibit the effectiveness of a research team. This keynote suggests a set of effective strategies to address the issues that emanate from the new field of research inquiry known as team science as well as lessons learned from tapping into research on organizational dynamics. © The Author(s) 2016.

Student goal orientation in learning inquiry skills with modifiable software advisors

NASA Astrophysics Data System (ADS)

Shimoda, Todd A.; White, Barbara Y.; Frederiksen, John R.

2002-03-01

A computer support environment (SCI-WISE) for learning and doing science inquiry projects was designed. SCI-WISE incorporates software advisors that give general advice about a skill such as hypothesizing. By giving general advice (rather than step-by-step procedures), the system is intended to help students conduct experiments that are more epistemologically authentic. Also, students using SCI-WISE can select the type of advice the advisors give and when they give advice, as well as modify the advisors' knowledge bases. The system is based partly on a theoretical framework of levels of agency and goal orientation. This framework assumes that giving students higher levels of agency facilitates higher-level goal orientations (such as mastery or knowledge building as opposed to task completion) that in turn produce higher levels of competence. A study of sixth grade science students was conducted. Students took a pretest questionnaire that measured their goal orientations for science projects and their inquiry skills. The students worked in pairs on an open-ended inquiry project that requires complex reasoning about human memory. The students used one of two versions of SCI-WISE - one that was modifiable and one that was not. After finishing the project, the students took a posttest questionnaire similar to the pretest, and evaluated the version of the system they used. The main results showed that (a) there was no correlation of goal orientation with grade point average, (b) knowledge-oriented students using the modifiable version tended to rate SCI-WISE more helpful than task-oriented students, and (c) knowledge-oriented pairs using the nonmodifiable version tended to have higher posttest inquiry skills scores than other pair types.

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.

Realizing the Living Paper using the ProvONE Model for Reproducible Research

Science has advanced through traditional publications that codify research results as a permenant part of the scientific record. But because publications are static and atomic, researchers can only cite and reference a whole work when building on prior work of colleagues. The open source software model has demonstrated a new approach in which strong version control in an open environment can nurture an open ecosystem of software. Developers now commonly fork and extend software giving proper credit, with less repetition, and with confidence in the relationship to original software. Through initiatives like 'Beyond the PDF', an analogous model has been imagined for open science, in which software, data, analyses, and derived products become first class objects within a publishing ecosystem that has evolved to be finer-grained and is realized through a web of linked open data. We have prototyped a Living Paper concept by developing the ProvONE provenance model for scientific workflows, with prototype deployments in DataONE. ProvONE promotes transparency and openness by describing the authenticity, origin, structure, and processing history of research artifacts and by detailing the steps in computational workflows that produce derived products. To realize the Living Paper, we decompose scientific papers into their constituent products and publish these as compound objects in the DataONE federation of archival repositories. Each individual finding and sub-product of a reseach project (such as a derived data table, a workflow or script, a figure, an image, or a finding) can be independently stored, versioned, and cited. ProvONE provenance traces link these fine-grained products within and across versions of a paper, and across related papers that extend an original analysis. This allows for open scientific publishing in which researchers extend and modify findings, creating a dynamic, evolving web of results that collectively represent the scientific enterprise. The Living Paper provides detailed metadata for properly interpreting and verifying individual research findings, for tracing the origin of ideas, for launching new lines of inquiry, and for implementing transitive credit for research and engineering.

2014-12-01

The National Research Council (2012) has expressed a need for participatory science experiences for students. Opportunities are needed for students which 1) allow them to understand how scientific knowledge develops and 2) can heighten their curiosity, capture their interest, and motivate their continued study of science. Studies (e.g., Aydeniz et al., 2011) have also recommend educators provide students with opportunities to do science through extracurricular work with scientists. In addition to being given the opportunity to fully participate in the scientific enterprise, students must also be explicitly guided in their attempts to develop a more appropriate understanding of the nature of the scientific enterprise (McDonald, 2010; Rudge & Howe, 2010; Yacoubian & BouJaoude, 2010). Exploration of the Moon and Asteroids by Secondary Students, or ExMASS, provides such an opportunity for students. The ExMASS program is an education effort managed by the LPI/NASA JSC-led Center for Lunar Science and Exploration (CLSE), one of nine teams comprising NASA's Solar System Exploration Research Virtual Institute (SSERVI). Over the course of one academic year, teams of high school students conduct their own scientific investigations of either Earth's Moon or asteroids, with guidance from a scientist mentor. The program includes two elements: 1) a guided inquiry introductory research activity that builds student knowledge of current lunar/asteroid science and lunar/asteroid data, and 2) an open inquiry research project in which the students apply their knowledge to a self-defined project. Evaluation data collected during the predecessor program to ExMASS revealed many successes, but also room for improvement. In response, an Advisory Group consisting of past teachers and mentors was formed to address the gaps revealed in the evaluation data. The ExMASS program will continue to collect similar evaluation data including assessment of changes in students' lunar/asteroid content knowledge, student attitudes toward science and science careers, and views of the nature of science and scientific inquiry. Exit surveys for teachers, students, and mentors will also be used to gather general feedback about the program and its impact.

How can science education foster students' rooting?

NASA Astrophysics Data System (ADS)

Østergaard, Edvin

2015-06-01

The question of how to foster rooting in science education points towards a double challenge; efforts to prevent (further) uprooting and efforts to promote rooting/re-rooting. Wolff-Michael Roth's paper discusses the uprooting/rooting pair of concepts, students' feeling of alienation and loss of fundamental sense of the earth as ground, and potential consequences for teaching science in a rooted manner. However, the argumentation raises a number of questions which I try to answer. My argumentation rests on Husserl's critique of science and the "ontological reversal", an ontological position where abstract models from science are considered as more real than the everyday reality itself, where abstract, often mathematical, models are taken to be the real causes behind everyday experiences. In this paper, measures towards an "ontological re-reversal" are discussed by drawing on experiences from phenomenon-based science education. I argue that perhaps the most direct and productive way of promoting rooting in science class is by intentionally cultivating the competencies of sensing and aesthetic experience. An aesthetic experience is defined as a precognitive, sensuous experience, an experience that is opened up for through sensuous perception. Conditions for rooting in science education is discussed against three challenges: Restoring the value of aesthetic experience, allowing time for open inquiry and coping with curriculum. Finally, I raise the question whether dimensions like "reality" or "nature" are self-evident for students. In the era of constructivism, with its focus on cognition and knowledge building, the inquiry process itself has become more important than the object of inquiry. I argue that as educators of science teachers we have to emphasize more explicitly "the nature of nature" as a field of exploration.

Improving forensic mental health care to Indigenous Australians: theorizing the intercultural space.

PubMed

Durey, A; Wynaden, D; O'Kane, M

2014-05-01

This paper uses the 'intercultural space' as an educational strategy to prepare nurses to work respectfully with Indigenous patients in a forensic mental health context; offers an educational approach that introduces nurses to Indigenous knowledge, beliefs and values, examines power relations in colonized countries between the dominant white cultural group and the Indigenous population and encourages nurses to critically reflect on their health care practice; and explores the intercultural space as a shared space between cultures fostering open and robust inquiry where neither culture dominates and new positions, representations and understandings can emerge. Given the disproportionately high number of Indigenous people imprisoned in colonized countries, this paper responds to research from Western Australia on the need to prepare forensic mental health nurses to deliver care to Indigenous patients with mental health disorders. The paper highlights the nexus between theory, research and education that can inform the design and implementation of programmes to help nurses navigate the complex, layered and contested 'intercultural space' and deliver culturally safe care to Indigenous patients. Nurses are encouraged to critically reflect on how beliefs and values underpinning their cultural positioning impact on health care to Indigenous patients. The paper draws on intercultural theory to offer a pedagogical framework that acknowledges the negative impacts of colonization on Indigenous health and well-being, repositions and revalues Indigenous cultures and knowledges and fosters open and robust inquiry. This approach is seen as a step towards working more effectively in the intercultural space where ultimately binary oppositions that privilege one culture over another and inhibit robust inquiry are avoided, paving the way for new, more inclusive positions, representations and understandings to emerge. While the intercultural space can be a place of struggle, tension and ambiguity, it also offers deep potential for change. © 2013 John Wiley & Sons Ltd.

Supporting pre-service elementary teachers in their understanding of inquiry teaching through the construction of a third discursive space

NASA Astrophysics Data System (ADS)

Greca, Ileana M.

2016-03-01

Several international reports promote the use of the inquiry teaching methodology for improvements in science education at elementary school. Nevertheless, research indicates that pre-service elementary teachers have insufficient experience with this methodology and when they try to implement it, the theory they learnt in their university education clashes with the classroom practice they observe, a problem that has also been noted with other innovative methodologies. So, it appears essential for pre-service teachers to conduct supportive reflective practice during their education to integrate theory and practice, which various studies suggest is not usually done. Our study shows how opening up a third discursive space can assist this supportive reflective practice. The third discursive space appears when pre-service teachers are involved in specific activities that allow them to contrast the discourses of theoretical knowledge taught at university with practical knowledge arising from their ideas on science and science teaching and their observations during classroom practice. The case study of three pre-service teachers shows that this strategy was fundamental in helping them to integrate theory and practice, resulting in a better understanding of the inquiry methodology and its application in the classroom.

Psychology as a Science of Subject and Comportment, beyond the Mind and Behavior.

PubMed

Pérez-Álvarez, Marino

2018-03-01

The turn of qualitative inquiry suggests a more open, plural conception of psychology than just the science of the mind and behavior as it is most commonly defined. Historical, ontological and epistemological binding of this conception of psychology to the positivist method of natural science may have exhausted its possibilities, and after having contributed to its prestige as a science, has now become an obstacle. It is proposed that psychology be reconceived as a science of subject and comportment in the framework of a contextual hermeneutic, social, human behavioral science. Thus, without rejecting quantitative inquiry, psychology recovers territory left aside like introspection and pre-reflective self-awareness, and reconnects with traditions marginalized from the main stream. From this perspective psychology might also recover its credibility as a human science in view of current skepticism.

Simulating Open Quantum Systems with Hamiltonian Ensembles and the Nonclassicality of the Dynamics

NASA Astrophysics Data System (ADS)

Chen, Hong-Bin; Gneiting, Clemens; Lo, Ping-Yuan; Chen, Yueh-Nan; Nori, Franco

2018-01-01

The incoherent dynamical properties of open quantum systems are generically attributed to an ongoing correlation between the system and its environment. Here, we propose a novel way to assess the nature of these system-environment correlations by examining the system dynamics alone. Our approach is based on the possibility or impossibility to simulate open-system dynamics with Hamiltonian ensembles. As we show, such (im)possibility to simulate is closely linked to the system-environment correlations. We thus define the nonclassicality of open-system dynamics in terms of the nonexistence of a Hamiltonian-ensemble simulation. This classifies any nonunital open-system dynamics as nonclassical. We give examples for open-system dynamics that are unital and classical, as well as unital and nonclassical.

Rawification and the careful generation of open government data.

PubMed

Denis, Jérôme; Goëta, Samuel

2017-10-01

Drawing on a two-year ethnographic study within several French administrations involved in open data programs, this article aims to investigate the conditions of the release of government data - the rawness of which open data policies require. This article describes two sets of phenomena. First, far from being taken for granted, open data emerge in administrations through a progressive process that entails uncertain collective inquiries and extraction work. Second, the opening process draws on a series of transformations, as data are modified to satisfy an important criterion of open data policies: the need for both human and technical intelligibility. There are organizational consequences of these two points, which can notably lead to the visibilization or the invisibilization of data labour. Finally, the article invites us to reconsider the apparent contradiction between the process of data release and the existence of raw data. Echoing the vocabulary of one of the interviewees, the multiple operations can be seen as a 'rawification' process by which open government data are carefully generated. Such a notion notably helps to build a relational model of what counts as data and what counts as work.

"I am a scientist": How setting conditions that enhance focused concentration positively relate to student motivation and achievement outcomes in inquiry-based science

NASA Astrophysics Data System (ADS)

Ellwood, Robin B.

This research investigated how student social interactions within two approaches to an inquiry-based science curriculum could be related to student motivation and achievement outcomes. This qualitative case study consisted of two cases, Off-Campus and On-Campus, and used ethnographic techniques of participant observation. Research participants included eight eighth grade girls, aged thirteen to fourteen years old. Data sources included formal and informal participant interviews, participant journal reflections, curriculum artifacts including quizzes, worksheets, and student-generated research posters, digital video and audio recordings, photographs, and researcher field notes. Data were transcribed verbatim and coded, then collapsed into emergent themes using NVIVO 9. The results of this research illustrate how setting conditions that promote focused concentration and communicative interactions can be positively related to student motivation and achievement outcomes in inquiry-based science. Participants in the Off-Campus case experienced more frequent states of focused concentration and out performed their peers in the On-Campus case on forty-six percent of classroom assignments. Off-Campus participants also designed and implemented a more cognitively complex research project, provided more in-depth analyses of their research results, and expanded their perceptions of what it means to act like a scientist to a greater extent than participants in the On-Campus case. These results can be understood in relation to Flow Theory. Student interactions that promoted the criteria necessary for initiating flow, which included having clearly defined goals, receiving immediate feedback, and maintaining a balance between challenges and skills, fostered enhanced student motivation and achievement outcomes. This research also illustrates the positive gains in motivation and achievement outcomes that emerge from student experiences with extended time in isolated areas referred to as "hot spots." Implications for science teaching and future research include shifting the current focus in inquiry-based science from a continuum that progresses from teacher-directed to open inquiry experiences to a continuum that also deliberately includes and promotes the necessary criteria for establishing flow. Attending to Flow Theory and incorporating student experiences with flow into inquiry-based science lessons will enhance student motivation and achievement outcomes in science and bolster the success of inquiry-based science.

Collective inquiry in the context of school-wide reform: Exploring science curriculum and instruction through team-based professional development

NASA Astrophysics Data System (ADS)

Eddy Spicer, David Henning

Teacher collaboration and joint reflective inquiry have been viewed as central elements of progressive educational reform for more than two decades. More recently, researchers, policy-makers, and practitioners have heralded "blended" or "hybrid" approaches that combine online and on-site environments for collaborative learning as especially promising for "scaling up" instructional improvement. Yet, relatively little is known about how teachers working together navigate organizational and interpersonal constraints to develop and sustain conditions essential to collective inquiry. This in-depth study of meaning making about curriculum and instruction among a group of 11 physics teachers in a public, urban secondary school in the U.S. is an effort to explore collective inquiry as a resource for teacher learning and innovations in teaching practice. Through extended observations, multiple interviews, and close analyses of interaction, the study followed teachers for 7 months as they worked together across 3 settings organized in fundamentally different ways to promote joint inquiry into teaching practice. The explanatory framework of the study rests on the mutually-reinforcing conceptual underpinnings of sociocultural theory and systemic functional linguistics to establish connections between micro-social interactions and macro-social processes. Drawing on systemic functional linguistics, the study explores interpersonal meaning making through close analyses of speech function and speech role in 6 extended sequences of generative interaction. Concepts from activity theory elucidate those features of settings and school that directly impinged on or advanced teachers' collaborative work. Findings run counter to prevailing congenial views of teacher collegiality by identifying ways in which collective inquiry is inherently unstable. That instability makes itself apparent at two levels: (a) the dynamics of authority within the group, and (b) middle-level features of setting and school that favored preserving solidarity above developing a critical stance towards practice. The study offers a theoretically-informed description of collective inquiry and an analytic framework to trace its development in naturally-occurring interaction. The analytic framework extends the tools of functional analysis into a new realm, that of teachers' collaborative work, and offers means to understand better the complex array of forces shaping and shaped by teachers' everyday interactions around their practice.

Dynamic hyperbolic geometry: building intuition and understanding mediated by a Euclidean model

NASA Astrophysics Data System (ADS)

Moreno-Armella, Luis; Brady, Corey; Elizondo-Ramirez, Rubén

2018-05-01

This paper explores a deep transformation in mathematical epistemology and its consequences for teaching and learning. With the advent of non-Euclidean geometries, direct, iconic correspondences between physical space and the deductive structures of mathematical inquiry were broken. For non-Euclidean ideas even to become thinkable the mathematical community needed to accumulate over twenty centuries of reflection and effort: a precious instance of distributed intelligence at the cultural level. In geometry education after this crisis, relations between intuitions and geometrical reasoning must be established philosophically, rather than taken for granted. One approach seeks intuitive supports only for Euclidean explorations, viewing non-Euclidean inquiry as fundamentally non-intuitive in nature. We argue for moving beyond such an impoverished approach, using dynamic geometry environments to develop new intuitions even in the extremely challenging setting of hyperbolic geometry. Our efforts reverse the typical direction, using formal structures as a source for a new family of intuitions that emerge from exploring a digital model of hyperbolic geometry. This digital model is elaborated within a Euclidean dynamic geometry environment, enabling a conceptual dance that re-configures Euclidean knowledge as a support for building intuitions in hyperbolic space-intuitions based not directly on physical experience but on analogies extending Euclidean concepts.

Community and inquiry: journey of a science teacher

NASA Astrophysics Data System (ADS)

Goldberg, Jennifer; Welsh, Kate Muir

2009-09-01

In this case study, we examine a teacher's journey, including reflections on teaching science, everyday classroom interaction, and their intertwined relationship. The teacher's reflections include an awareness of being "a White middle-class born and raised teacher teaching other peoples' children." This awareness was enacted in the science classroom and emerges through approaches to inquiry . Our interest in Ms. Cook's journey grew out of discussions, including both informal and semi-structured interviews, in two research projects over a three-year period. Our interest was further piqued as we analyzed videotaped classroom interaction during science lessons and discovered connections between Ms. Cook's reflections and classroom interaction. In this article, we illustrate ways that her journey emerges as a conscientization. This, at least in part, shapes classroom interaction, which then again shapes her conscientization in a recursive, dynamic relationship. We examine her reflections on her "hegemonic (cultural and socio-economic) practices" and consider how these reflections help her reconsider such practices through analysis of classroom interaction. Analyses lead us to considering the importance of inquiry within this classroom community.

PAQ: Persistent Adaptive Query Middleware for Dynamic Environments

NASA Astrophysics Data System (ADS)

Rajamani, Vasanth; Julien, Christine; Payton, Jamie; Roman, Gruia-Catalin

Pervasive computing applications often entail continuous monitoring tasks, issuing persistent queries that return continuously updated views of the operational environment. We present PAQ, a middleware that supports applications' needs by approximating a persistent query as a sequence of one-time queries. PAQ introduces an integration strategy abstraction that allows composition of one-time query responses into streams representing sophisticated spatio-temporal phenomena of interest. A distinguishing feature of our middleware is the realization that the suitability of a persistent query's result is a function of the application's tolerance for accuracy weighed against the associated overhead costs. In PAQ, programmers can specify an inquiry strategy that dictates how information is gathered. Since network dynamics impact the suitability of a particular inquiry strategy, PAQ associates an introspection strategy with a persistent query, that evaluates the quality of the query's results. The result of introspection can trigger application-defined adaptation strategies that alter the nature of the query. PAQ's simple API makes developing adaptive querying systems easily realizable. We present the key abstractions, describe their implementations, and demonstrate the middleware's usefulness through application examples and evaluation.

From Teacher-at-Sea to Authentic Science in the Classroom

NASA Astrophysics Data System (ADS)

Holzer, M. A.; Laj, C.

2007-12-01

Research has shown that most teachers will teach the way they have been taught, unless a sustainable intervention has taken place. This has the greatest implications for teachers of science, where those who have been taught with inquiry approaches will employ inquiry approaches in their classrooms, and those who have been taught with lecture and note taking will teach primarily using lectures and note taking. If our children are to learn about the nature of science, they need to be taught using constructivist and inquiry methods. A teacher who only uses textbooks and lectures will not create students who can employ critical thinking skills indicative of the nature of science. There is a way to change the way our teachers teach science, and that is by exposing teachers to authentic inquiry. The Teacher at Sea Program sponsored by Institut Polaire Francais (IPEV) created such an opportunity for 4 teachers, who participated in the PACHIDERME deep sea sediment cruise on the R/V Marion Dufresne off the coast of Chile for 3 weeks in February, 2007. While onboard the teachers assisted research scientists from France, Germany, Norway, and Chile in their quest to gather and analyze sediment cores for clues to past climates. The teachers were immersed in the research projects right from the start. They all participated in a "watch" and assisted those on the watch with the processing of the cores, which included properly labeling and packaging each of the core segments. Prior to the packaging, preliminary analysis was done to identify the physical and biological attributes of the core. The scientists gave of their time to coach the teachers not only on the techniques they were using, but also on the process of science. Whether it's working on an unstable platform, coring into the unknown, or adjusting to the weather that Mother Nature brings, the nature and process of science out at sea is complicated. The teachers came to realize this as they sailed in and out of the fjord region and into the open ocean off the coast of Chile, and shared these experiences with colleagues and students from around the world. They sent daily logs via email, sent pictures, and answered questions sent by teachers and students from Europe, the United States, and Chile. Students kept journals as they followed the daily events of the teachers at sea. A powerpoint presentation documenting the scientific endeavors of the cruise was created and is being used by many teachers as a tool to show how scientific research is done at sea. Was this cruise effective in changing the teaching styles of those teachers on board? The teachers observed how scientists generate questions, propose study plans, and employ creative methods to answer those questions. Having witnessed the nature and process first hand, these teachers reassessed their teaching styles for scientific validity. They are employing a greater number of open/full inquiry projects where the students are constructing and seeking to answer their own questions. These students will leave their classes knowing about the challenges of doing science, and the excitement in doing science. Whether it's out at sea, in the field, or in a lab, the participation of teachers in authentic inquiry is the best way to ensure our students are participating in authentic inquiry.

In Vivo Time-Lapse Imaging in the Zebrafish Lateral Line: A Flexible, Open-Ended Research Project for an Undergraduate Neurobiology Laboratory Course.

PubMed

Marra, Molly H; Tobias, Zachary J C; Cohen, Hannah R; Glover, Greta; Weissman, Tamily A

2015-01-01

The lateral line sensory system in fish detects movements in the water and allows fish to respond to predators, prey, and other stimuli. As the lateral line forms in the first two days of zebrafish development, axons extend caudally along the lateral surface of the fish, eventually forming synapses with hair cells of neuromasts. Growing lateral line axons are located superficially under the skin and can be labeled in living zebrafish using fluorescent protein expression. This system provides a relatively straightforward approach for in vivo time-lapse imaging of neuronal development in an undergraduate setting. Here we describe an upper-level neurobiology laboratory module in which students investigate aspects of axonal development in the zebrafish lateral line system. Students learn to handle and image living fish, collect time-lapse videos of moving mitochondria, and quantitatively measure mitochondrial dynamics by generating and analyzing kymographs of their movements. Energy demands may differ between axons with extending growth cones versus axons that have already reached their targets and are forming synapses. Since relatively little is known about this process in developing lateral line axons, students generate and test their own hypotheses regarding how mitochondrial dynamics may differ at two different time points in axonal development. Students also learn to incorporate into their analysis a powerful yet accessible quantitative tool, the kymograph, which is used to graph movement over time. After students measure and quantify dynamics in living fish at 1 and 2 days post fertilization, this module extends into independent projects, in which students can expand their studies in a number of different, inquiry-driven directions. The project can also be pared down for courses that wish to focus solely on the quantitative analysis (without fish handling), or vice versa. This research module provides a useful approach for the design of open-ended laboratory research projects that integrate the scientific process into undergraduate Biology courses, as encouraged by the AAAS and NSF Vision and Change Initiative.

Concepts and implications of altruism bias and pathological altruism

PubMed Central

Oakley, Barbara A.

2013-01-01

The profound benefits of altruism in modern society are self-evident. However, the potential hurtful aspects of altruism have gone largely unrecognized in scientific inquiry. This is despite the fact that virtually all forms of altruism are associated with tradeoffs—some of enormous importance and sensitivity—and notwithstanding that examples of pathologies of altruism abound. Presented here are the mechanistic bases and potential ramifications of pathological altruism, that is, altruism in which attempts to promote the welfare of others instead result in unanticipated harm. A basic conceptual approach toward the quantification of altruism bias is presented. Guardian systems and their over arching importance in the evolution of cooperation are also discussed. Concepts of pathological altruism, altruism bias, and guardian systems may help open many new, potentially useful lines of inquiry and provide a framework to begin moving toward a more mature, scientifically informed understanding of altruism and cooperative behavior.

2017-01-01

The article explores undergraduate students' experiences of developing mindful agency as a positive learning disposition, their perceived change as a learner, and the possible impact of mindful agency coaching on students' learning and personal growth, using a narrative research method. Seventy Chinese undergraduate students generated personal reflective journals and eight participants' journals were selected to enter into the narrative-oriented inquiry. Our analysis revealed a number of primary themes based on which we produced a meta-story. The supplements of the story were exacted for further critical cross-case discussion. The finding indicated that the multifaceted development of mindful agency involved learning methods, emotional regulation, strategic thinking, and awareness of planning, openness to experience, self-acceptance and self-esteem, and learning engagement, with enhanced sense of personal awareness and awakening. The coaching was supportive for students to foster positive self-identities and become more reflective, mindful, and self-determined. PMID:29209260

The science commons in health research: structure, function, and value.

PubMed

Cook-Deegan, Robert

The "science commons," knowledge that is widely accessible at low or no cost, is a uniquely important input to scientific advance and cumulative technological innovation. It is primarily, although not exclusively, funded by government and nonprofit sources. Much of it is produced at academic research centers, although some academic science is proprietary and some privately funded R&D enters the science commons. Science in general aspires to Mertonian norms of openness, universality, objectivity, and critical inquiry. The science commons diverges from proprietary science primarily in being open and being very broadly available. These features make the science commons particularly valuable for advancing knowledge, for training innovators who will ultimately work in both public and private sectors, and in providing a common stock of knowledge upon which all players-both public and private-can draw readily. Open science plays two important roles that proprietary R&D cannot: it enables practical benefits even in the absence of profitable markets for goods and services, and its lays a shared foundation for subsequent private R&D. The history of genomics in the period 1992-2004, covering two periods when genomic startup firms attracted significant private R&D investment, illustrates these features of how a science commons contributes value. Commercial interest in genomics was intense during this period. Fierce competition between private sector and public sector genomics programs was highly visible. Seemingly anomalous behavior, such as private firms funding "open science," can be explained by unusual business dynamics between established firms wanting to preserve a robust science commons to prevent startup firms from limiting established firms' freedom to operate. Deliberate policies to create and protect a large science commons were pursued by nonprofit and government funders of genomics research, such as the Wellcome Trust and National Institutes of Health. These policies were crucial to keeping genomic data and research tools widely available at low cost.

Science Classroom Inquiry (SCI) Simulations: A Novel Method to Scaffold Science Learning

Science education is progressively more focused on employing inquiry-based learning methods in the classroom and increasing scientific literacy among students. However, due to time and resource constraints, many classroom science activities and laboratory experiments focus on simple inquiry, with a step-by-step approach to reach predetermined outcomes. The science classroom inquiry (SCI) simulations were designed to give students real life, authentic science experiences within the confines of a typical classroom. The SCI simulations allow students to engage with a science problem in a meaningful, inquiry-based manner. Three discrete SCI simulations were created as website applications for use with middle school and high school students. For each simulation, students were tasked with solving a scientific problem through investigation and hypothesis testing. After completion of the simulation, 67% of students reported a change in how they perceived authentic science practices, specifically related to the complex and dynamic nature of scientific research and how scientists approach problems. Moreover, 80% of the students who did not report a change in how they viewed the practice of science indicated that the simulation confirmed or strengthened their prior understanding. Additionally, we found a statistically significant positive correlation between students’ self-reported changes in understanding of authentic science practices and the degree to which each simulation benefitted learning. Since SCI simulations were effective in promoting both student learning and student understanding of authentic science practices with both middle and high school students, we propose that SCI simulations are a valuable and versatile technology that can be used to educate and inspire a wide range of science students on the real-world complexities inherent in scientific study.

Some Key Issues in Creating Inquiry-Based Instructional Practices that Aim at the Understanding of Simple Electric Circuits

Kock, Zeger-Jan; Taconis, Ruurd; Bolhuis, Sanneke; Gravemeijer, Koeno

2013-04-01

Many students in secondary schools consider the sciences difficult and unattractive. This applies to physics in particular, a subject in which students attempt to learn and understand numerous theoretical concepts, often without much success. A case in point is the understanding of the concepts current, voltage and resistance in simple electric circuits. In response to these problems, reform initiatives in education strive for a change of the classroom culture, putting emphasis on more authentic contexts and student activities containing elements of inquiry. The challenge then becomes choosing and combining these elements in such a manner that they foster an understanding of theoretical concepts. In this article we reflect on data collected and analyzed from a series of 12 grade 9 physics lessons on simple electric circuits. Drawing from a theoretical framework based on individual (conceptual change based) and socio-cultural views on learning, instruction was designed addressing known conceptual problems and attempting to create a physics (research) culture in the classroom. As the success of the lessons was limited, the focus of the study became to understand which inherent characteristics of inquiry based instruction complicate the process of constructing conceptual understanding. From the analysis of the data collected during the enactment of the lessons three tensions emerged: the tension between open inquiry and student guidance, the tension between students developing their own ideas and getting to know accepted scientific theories, and the tension between fostering scientific interest as part of a scientific research culture and the task oriented school culture. An outlook will be given on the implications for science lessons.

Empirical population and public health ethics: A review and critical analysis to advance robust empirical-normative inquiry.

PubMed

Knight, Rod

2016-05-01

The field of population and public health ethics (PPHE) has yet to fully embrace the generation of evidence as an important project. This article reviews the philosophical debates related to the 'empirical turn' in clinical bioethics, and critically analyses how PPHE has and can engage with the philosophical implications of generating empirical data within the task of normative inquiry. A set of five conceptual and theoretical issues pertaining to population health that are unresolved and could potentially benefit from empirical PPHE approaches to normative inquiry are discussed. Each issue differs from traditional empirical bioethical approaches, in that they emphasize (1) concerns related to the population, (2) 'upstream' policy-relevant health interventions - within and outside of the health care system and (3) the prevention of illness and disease. Within each theoretical issue, a conceptual example from population and public health approaches to HIV prevention and health promotion is interrogated. Based on the review and critical analysis, this article concludes that empirical-normative approaches to population and public health ethics would be most usefully pursued as an iterative project (rather than as a linear project), in which the normative informs the empirical questions to be asked and new empirical evidence constantly directs conceptualizations of what constitutes morally robust public health practices. Finally, a conceptualization of an empirical population and public health ethics is advanced in order to open up new interdisciplinary 'spaces', in which empirical and normative approaches to ethical inquiry are transparently (and ethically) integrated. © The Author(s) 2015.

The evolution of science literacy: Examining intertextual connections and inquiry behaviors in the classroom

NASA Astrophysics Data System (ADS)

Manocchi-Verrino, Carol J.

A call for a new perspective of science literacy has been marked as the impetus of change in science education, suggesting that a meaning-making approach to literacy and inquiry are central to learning science. This research study explored how science literacy evolved in a classroom where this reconceptualized view of science literacy guided curriculum design and instruction. The teacher/researcher incorporated Interactive Science Notebooks (ISNs) and Interactive Reading Organizers and Comprehension Strategies (IROCS) into instructional materials. In a class consisting of 20 mainstream and special education students, this 7-week study collected data using Likert scales, stimulated recall interviews, a teacher/researcher journal, and students¡¦ position papers. A systematic design framework was used for the three-phase analysis. Hyperresearch RTM software facilitated the identification of open codes, an axial code, and frequency graphs. In order to develop insight into the relationship between questions, methods, and curriculum design recent recommendations for quality research in science education were considered in the methodology. The hypothesis formulated from the data suggests that science literacy evolves on a continuum, and the degree to which science literacy evolves on the continuum seems to be contingent upon their uses of intertextual connections and inquiry behaviors. Several notable insights emerged from the data which were used to guide curriculum, instruction, and assessment that promotes the development of science literacy in the middle school classroom. The study suggests a possible correlation between the use of intertextual connections and inquiry behaviors, and the use of a continuum in measuring the emergence of science literacy.

Enhancing Science Education Instruction: A Mixed-Methods Study on University and Middle School Collaborations

Owen-Stone, Deborah S.

The purpose of this concurrent mixed methods study was to examine the collaborative relationship between scientists and science teachers and to incorporate and advocate scientific literacy based on past and current educational theories such as inquiry based teaching. The scope of this study included archived student standardized test scores, semi-structured interviews, and a Likert scale survey to include open-ended comments. The methodology was based on the guiding research question: To what extent and in what ways does the collaboration and inquiry methodology, with GTF and PT teams, serve toward contributing to a more comprehensive and nuanced understanding of this predicting relationship between student PASS scores, inquiry skills, and increased scientific literacy for GTF's, PT's, and students via an integrative mixed methods analysis? The data analysis considerations were derived from the qualitative data collected from the three GTF/PT teams by the use of recorded interviews and text answered survey comments. The quantitative data of archived student Palmetto Assessment of State Standards (PASS) scores on scientific literacy and inquiry tests and the Likert-scale portion of the survey were support data to the aforementioned qualitative data findings. Limitations of the study were (1) the population of only the GK-12 teachers and their students versus the inclusion of participants that did not experience the GK-12 Fellow partnerships within their classrooms, should they be considered as participants, (2) involved the researcher as a participant for two years of the program and objectivity remained through interpretation and well documented personal reflections and experiences to inform accuracy, and (3) cultural diversity contributed to the relationship formed between the research Fellow and science educator and communication and scientific language did form a barrier between the Fellow, educator, and student rapport within the classroom. This study's contribution benefits science education, scientists, university science education, and future collaborations. Key Terms: mixed methods, GK-12, scientific literacy, inquiry, collaboration.

Negotiating Competing Goals in the Development of an Urban Ecology Practitioner Inquiry Community

Teacher learning communities are hailed by many as vehicles for reforming and elevating the professional status of teaching. While much research explores teacher community as a venue for measurable gains, our research examines the orientation of practitioner inquiry toward critical debate about effective instruction. Specifically, our study focuses on a group of middle and high school teachers who worked with a nonprofit organization to engage students in urban environmental field investigations. Teachers met regularly as a community with the common goal of teaching urban ecology in an outdoor setting. We collected interview data from members of the teacher community, and we observed teacher interaction during a meeting of the practitioner inquiry group. Interview results indicated that while the nonprofit aimed to support collaborative dialogue and self-critique, participants saw the community mainly as a venue for pursuing short-term goals, such as receiving new resources or socializing with colleagues. Observation data, however, suggested that the community was taking early steps toward building an environment oriented toward critical discussion. Juxtaposing results from our interviews and observations, we discuss the challenges communities face when they seek to develop shared beliefs and deal openly with conflict. Ultimately, we suggest that organizers of collaborative learning environments should work to actively develop structures for building the organizational trust necessary to support civil critique.

A Structured-Inquiry Approach to Teaching Neurophysiology Using Computer Simulation

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

Physicians' opening questions and patients' satisfaction.

Robinson, Jeffrey D; Heritage, John

2006-03-01

To determine the association between the format of physicians' opening questions that solicit patients' presenting concerns and patients' post-visit evaluations of (i.e., satisfaction with) the affective-relational dimension of physicians' communication. Videotape and questionnaire data were collected from visits between 28 primary-care physicians and 142 adult patients with acute problems. Factor analysis resulted in three dependent variables derived from the 9-item Socioemotional Behavior subscale of the Medical Interview Satisfaction Scale. Question format was significantly, positively associated with patients' evaluations of physicians' listening (p=.028) and positive affective-relational communication (p=.046). Patients desire opportunities to present concerns in their own time and terms regardless of how extensively they act on this opportunity. Visits should be opened with general inquiries (e.g., What can I do for you today?) versus closed-ended requests for confirmation (e.g., Sore throat, huh?).

Openness versus Secrecy in Scientific Research Abstract

2009-01-01

Openness is one of the most important principles in scientific inquiry, but there are many good reasons for maintaining secrecy in research, ranging from the desire to protect priority, credit, and intellectual property, to the need to safeguard the privacy of research participants or minimize threats to national or international security. This article examines the clash between openness and secrecy in science in light of some recent developments in information technology, business, and politics, and makes some practical suggestions for resolving conflicts between openness and secrecy. “By academic freedom I understand the right to search for the truth and to publish and teach what one holds to be true. This right also implies a duty; one must not conceal any part of what one has recognized to be true. It is evident that any restriction of academic freedom serves to restrain the dissemination of knowledge, thereby impeding rational judgment and action.” Albert Einstein, quotation inscribed on his statute in front of the National Academy of Sciences, Washington, DC.

Shaping and reshaping the aesthetic brain: Emerging perspectives on the neurobiology of embodied aesthetics.

PubMed

Kirsch, Louise P; Urgesi, Cosimo; Cross, Emily S

2016-03-01

Less than two decades after its inception, the burgeoning field of neuroaesthetics continues to grow in interest and momentum. Despite the biological and social importance of the human body and the attention people pay to its appearance in daily life, only recently has neuroaesthetic inquiry turned its attention to questions concerning the aesthetic appraisal of the human body. We review evidence illustrating that the complexity of aesthetic experience is reflected by dynamic interplay between brain systems involved in reward, perceptual and motor processing, with a focus on aesthetic perception involving the human body. We then evaluate work demonstrating how these systems are modulated by beholders' expertise or familiarity. Finally, we discuss seminal studies revealing the plasticity of behavioural and neural responses to beauty after perceptual and motor training. This research highlights the rich potential for neuroaesthetic inquiry to extend beyond its typical realm of the fine arts to address important questions regarding the relationship between embodiment, aesthetics and performing arts. We conclude by considering some of the criticisms and limitations of neuroaesthetics, and highlight several outstanding issues for future inquiry. Copyright © 2016 The Authors.

A key factor that may contribute to communication failures is status asymmetry between team members. We examined the effect of a consultant anaesthetist's interpersonal behaviour on trainees' ability to effectively challenge clearly incorrect clinical decisions. Thirty-four trainees were recruited to participate in a video-recorded scenario of an airway crisis. They were randomised to a group in which a confederate consultant anaesthetist's interpersonal behaviour was scripted to recreate either a strict/exclusive or an open/inclusive communication dynamic. The scenario allowed trainees four opportunities to challenge clearly wrong decisions. Performances were scored using the modified Advocacy-Inquiry Score. The highest median (IQR [range]) score was 3.0 (2.2-4.0 [1.0-5.0]) in the exclusive communication group, and 3.5 (3.0-4.5 [2.5-6.0]) in the inclusive communication group (p = 0.06). The study did not show a significant effect of consultant behaviour on trainees' ability to challenge their superior. It did demonstrate trainees' inability to challenge their seniors effectively, resulting in critical communication gaps. © 2015 The Association of Anaesthetists of Great Britain and Ireland.

Shifting the Balance: Relationship as Power in Organizational Life.

Davidson, Sandra J

2015-01-01

Power has traditionally been studied and experienced within organizations from a hierarchical and positivist perspective. However, organizational complexity has never been greater, and in our attempts to find new ways to live amid this complexity we seek alternative theoretical perspectives that may better represent and inform our experiences of organizational life. This article summarizes the positivist view of power within organizations and the limitations of attempting to study power from this perspective. Power is then reconceptualized and explored using the complex responsive process (CRP) analysis. This is an exemplar of how narrative inquiry guided by CRP may be used as a frame for reflexivity and reflection amid organizational power dynamics. The narrative description used in this paper was based on the author's experience and reflection upon a nursing faculty meeting in a large public university. By becoming aware of the power relations in which we engage, and by reflecting upon them using CRP, we may come to understand power relations in a different way. In the act of examining and reflecting on our habitual roles in power relations, we may open up the potential for personal and organizational transformation. © 2015 Wiley Periodicals, Inc.

An inquiry-based approach to the Franck-Hertz experiment

NASA Astrophysics Data System (ADS)

Persano Adorno, Dominique; Pizzolato, Nicola

2016-05-01

The practice of scientists and engineers is today exerted within interdisciplinary contexts, placed at the intersections of different research fields, including nanoscale science. The development of the required competences is based on an effective science and engineering instruction, which should be able to drive the students towards a deeper understanding of quantum mechanics fundamental concepts and, at the same time, strengthen their reasoning skills and transversal abilities. In this study we report the results of an inquiry-driven learning path experienced by a sample of 12 electronic engineering undergraduates engaged to perform the Franck-Hertz experiment. Before being involved in this experimental activity, the students received a traditional lecture-based instruction on the fundamental concepts of quantum mechanics, but their answers to an open-ended questionnaire, administered at the beginning of the inquiry activity, demonstrated that the acquired knowledge was characterized by a strictly theoretical vision of quantum science, basically in terms of an artificial mathematical framework having very poor connections with the real world. The Franck Hertz experiment was introduced to the students by starting from the problem of finding an experimental confirmation of the Bohr's postulates asserting that atoms can absorb energy only in quantum portions. The whole activity has been videotaped and this allowed us to deeply analyse the student perception's change about the main concepts of quantum mechanics. We have found that the active participation to this learning experience favored the building of cognitive links among student theoretical perceptions of quantum mechanics and their vision of quantum phenomena, within an everyday context of knowledge. Furthermore, our findings confirm the benefits of integrating traditional lecture-based instruction on quantum mechanics with learning experiences driven by inquiry-based teaching strategies.

Impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines

NASA Astrophysics Data System (ADS)

Marulcu, Ismail; Barnett, Michael

2016-01-01

Background: Elementary Science Education is struggling with multiple challenges. National and State test results confirm the need for deeper understanding in elementary science education. Moreover, national policy statements and researchers call for increased exposure to engineering and technology in elementary science education. The basic motivation of this study is to suggest a solution to both improving elementary science education and increasing exposure to engineering and technology in it. Purpose/Hypothesis: This mixed-method study examined the impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. We hypothesize that the LEGO-engineering design unit is as successful as the inquiry-based unit in terms of students' science content learning of simple machines. Design/Method: We used a mixed-methods approach to investigate our research questions; we compared the control and the experimental groups' scores from the tests and interviews by using Analysis of Covariance (ANCOVA) and compared each group's pre- and post-scores by using paired t-tests. Results: Our findings from the paired t-tests show that both the experimental and comparison groups significantly improved their scores from the pre-test to post-test on the multiple-choice, open-ended, and interview items. Moreover, ANCOVA results show that students in the experimental group, who learned simple machines with the design-based unit, performed significantly better on the interview questions. Conclusions: Our analyses revealed that the design-based Design a people mover: Simple machines unit was, if not better, as successful as the inquiry-based FOSS Levers and pulleys unit in terms of students' science content learning.

Digital Technology and Teacher Preparation: The Instructional Role of Social Media Among Pre-Service Teachers

NASA Astrophysics Data System (ADS)

Trytten, Bria Klotz

As social media use becomes more prevalent among teachers, it becomes vital to understand how teachers are using social media and what effects it has, if any, on teaching practices in the classroom. This study sought to explore the relationship between pre-service teachers' use of social media and their perceptions of inquiry-based science education, an important teaching best practice. This study is unique in that it explores pre-service teachers' use of three social media platforms--Twitter, Facebook, and Pinterest--and how pre-service teachers plan to apply them to classroom education. Previous studies focused on only one social media platform, usually Twitter or Facebook. This study surveyed 113 pre-service teachers in their 3rd or 4th year of school at one of two teacher colleges. The survey employed multiple choice, open-ended, and Likert-type questions to assess pre-service teachers' use of social media as well as their attitudes surrounding inquiry-based instruction. In order to better explain and analyze survey results, fourteen survey participants were interviewed with follow-up questions to elaborate on both social media use and inquiry attitudes. Findings indicated that the pre-service teachers used social media, and overwhelmingly Pinterest, to find lesson plans and classroom organizational ideas. Cited reasons for this practice included convenience, variety of lesson planning, and easily searchable databases. The study found statistical significance in that teachers who aspire to teach lower grade levels will turn to social media to find lesson plans more frequently than those who aspire to teach higher grade levels. The study found social media use had no statistically significant effect on the level of inquiry-based teaching that the participants aimed to achieve in their future classrooms.

In the course of learning astronomy, it is generally accepted that successful science learning experiences should result in learners developing a meaningful understanding of the nature of science as inquiry where: (i) students are engaged in questions; (ii) students are designing plans to pursue data; and (iii) students are generating and defending conclusions based on evidence they have collected. In support of these goals, we have systematically field-test three separate instructional tools that are ready to be field-tested beyond the United States. The first of these is called LECTURE-TUTORIALS. These are self-contained, classroom-ready, collaborative group activities. The materials are designed specifically to be easily integrated into the lecture course and directly address the needs of busy faculty for effective, student-centered, classroom-ready materials that do not require a drastic course revision for implementation. Students are asked to reason about difficult concepts, while working in pairs, and to discuss their ideas openly. The second of these is a series of computer-mediated, inquiry learning experiences based upon an inquiry-oriented teaching approach framed by the notions of BACKWARDS-FADED SCAFFOLDING as an overarching theme for instruction that leverage online science data. BFS is a strategy where the conventional and rigidly linear scientific method is turned on its head and students are first taught how to create conclusions based on evidence, then how experimental design creates evidence, and only at the end introduces students to - what we believe is the most challenging part of inquiry - inventing scientifically appropriate questions. Third, contemporary ASSESSMENT INSTRUMENTS, including the TOAST and EGGS surveys, for astronomy & geology have been developed to help teachers measure the success of their implementation. Evaluation results consistently suggest that these tools help teachers better engage students in self-directed scientific discourse and increase their knowledge.

What Works in Israeli Prison-Based Sex Offender Rehabilitation Programs: Program Participants' Perspective.

PubMed

Geiger, Brenda; Fischer, Michael

2017-09-01

This study invited 10 of the 22 sex offenders enrolled in a prison-based rehabilitation program in one of the prisons in Israel to engage in the two first of the 4-D ( Discover, Dream, Design, and Deliver) stages of the Appreciative Inquiry . Consistent with the responsivity principle, and the IA tenets, program participants were interviewed to Discover components to which they were responsive and Dream/envision additional ones that would increase engagement and progress. Content analysis of the interviews indicated that despite the initial decision to enrol based on external incentives, participants eventually engaged in group therapy and expressed the desire to understand and regulate their sexual behaviour. While the the modules of Cognitive Behabioral Group Therapy (CBT) were viewed as assets, the lack of sufficient recruitment criteria, the large therapy group size, and its open-ended structure were mentioned as impediments reaching therapeutic goals. Social workers/therapists were criticized for their request that they be informers, and for their accusative therapeutic style whenever sexual issues were broached. Recommendations derived from the offenders' narrative were to increase staff professionalism to create a therapeutic alliance that promotes trust and open communication. Criminal justice practitioners may then take up the challenge of the never-ending process of Appreciative Inquiry to Design and Deliver program components envisioned by the participants to increase participants' responsivity to the program and thus its effectiveness.

A strategy for monitoring and evaluating massive open online courses.

Chapman, S A; Goodman, S; Jawitz, J; Deacon, A

2016-08-01

We argue that the complex, innovative and adaptive nature of Massive Open Online Course (MOOC) initiatives poses particular challenges to monitoring and evaluation, in that any evaluation strategy will need to follow a systems approach. This article aims to guide organizations implementing MOOCs through a series of steps to assist them in developing a strategy to monitor, improve, and judge the merit of their initiatives. We describe how we operationalise our strategy by first defining the different layers of interacting agents in a given MOOC system. We then tailor our approach to these different layers. Specifically, a two-pronged approach was developed, where we suggest that individual projects be assessed through performance monitoring; assessment criteria for which would be defined at the outset to include coverage, participation, quality and student achievement. In contrast, the success of an overall initiative should be considered within a more adaptive, emergent evaluation inquiry framework. We present the inquiry framework we developed for MOOC initiatives, and show how this framework might be used to develop evaluation questions and an assessment methodology. We also define the more fixed indicators and measures for project performance monitoring. Our strategy is described as it was developed to inform the evaluation of a MOOC initiative at the University of Cape Town (UCT), South Africa. Copyright © 2016 Elsevier Ltd. All rights reserved.

Supporting Survey Courses with Lecture-Tutorials and Backwards-Faded Scaffolded Inquiry

2013-12-01

In the course of learning science, it is generally accepted that successful science learning experiences should result in learners developing a meaningful understanding of the nature of science as inquiry where: (i) students are engaged in questions; (ii) students are designing plans to pursue data; and (iii) students are generating and defending conclusions based on evidence they have collected. Few of these learning targets can be effectively reached through a professor-centered, information download lecture. In response to national reform movements calling for professors to adopt teaching strategies and learning environments where non-science majors and future teachers can actively engage in scientific discourse, scholars with the CAPER Center for Astronomy & Physics Education Research have leveraged NSF DUE funding over the last decade to develop and systematically field-test two separate instructional approaches. The first of these is called Lecture-Tutorials (NSF 99077755 and NSF 9952232) . These are self-contained, classroom-ready, collaborative group activities. The materials are designed specifically to be easily integrated into the lecture course and directly address the needs of busy and heavily-loaded teaching faculty for effective, student-centered, classroom-ready materials that do not require a drastic course revision for implementation. Students are asked to reason about difficult concepts, while working in pairs, and to discuss their ideas openly. The second of these is a series of computer-mediated, inquiry learning experiences for non-science majoring undergraduates based upon an inquiry-oriented teaching approach framed by the notions of backwards faded-scaffolding as an overarching theme for instruction (NSF 1044482). Backwards faded-scaffolding is a strategy where the conventional and rigidly linear scientific method is turned on its head and students are first taught how to create conclusions based on evidence, then how experimental design creates evidence, and only at the end introduces students to - what we believe is the most challenging part of inquiry - inventing scientifically appropriate questions. Dissemination efforts have been supported by NSF 0715517 and evaluation results consistently suggest that both the Lecture-Tutorials and the backwards faded-scaffolding approaches are successfully engaging students in self-directed scientific discourse as measured by the Views on Scientific Inquiry (VOSI) as well as increasing their knowledge of science as measured by various measures.

Independence of scientific publishing. Reaffirming the principle.

PubMed

Bjork, R A

2000-09-01

Historically, the American Psychological Association (APA), as part of its contract with the editors of APA journals, has granted to the editors sole responsibility to accept or reject manuscripts for publication, without such actions being open for review by APA. Such a policy fosters the freedom of inquiry and expression so necessary for a healthy science. It also serves to protect the Association because publication of an article in an APA journal does not represent endorsement by APA itself. The lessons of history are clear: When political or other pressures interfere with the autonomy of science, the societal and scientific consequences are grim. APA should reaffirm the principle that a healthy science of psychology requires an open exchange of ideas and findings.

Previous reports show that Chilean teenagers have an inadequate knowledge about sexuality and reproduction. To compare the knowledge about sexuality among adolescents coming from private and public schools, with and without sexual education programs. A structured anonymous inquiry, containing multiple choice and open questions, was applied to a sample of 229 adolescents attending seventh and eighth grade of junior school, in private and public schools of Temuco, Chile. Eleven percent of adolescents had already their first sexual intercourse at a mean age of 12.2 +/- 2.4 years old. Of these, 96% came from public schools. An overall analysis of tests, disclosed a 53% of correct answers to the inquiry. Adolescents coming from private schools had a better performance than those coming from public schools. Sexual attitudes were not influenced by sexual education programs. Adolescents coming from private schools have a better sexual knowledge level and more conservative attitudes towards sexuality. Overall knowledge is inadequate albeit overvalued. These teenagers are high risk group for unwanted pregnancies and sexually transmitted diseases and require efficient sexual education programs.

How does participation in inquiry-based activities influence gifted students' higher order thinking?

NASA Astrophysics Data System (ADS)

Reger, Barbara H.

Inquiry-based learning is considered a useful technique to strengthen the critical thinking skills of students. The National Science Standards emphasize its use and the complexities and challenge it provides are well suited for meeting the needs of the gifted. While many studies have documented the effectiveness of this type of instruction, there is a lack of research on growth in higher-order thinking through participation in science inquiry. This study investigated such growth among a small group of gifted fifth-grade students. In this study a group of fifth-grade gifted science students completed a series of three forensics inquiry lessons, and documented questions, ideas and reflections as they constructed evidence to solve a crime. From this class of students, one small group was purposely selected to serve as the focus of the study. Using qualitative techniques, the questions and statements students made as they interacted in the activity were analyzed. Videotaped comments and student logs were coded for emerging patterns and also examined for evidence of increased levels of higher-order thinking based on a rubric that was designed using the six levels of Bloom's Taxonomy. Evidence from this study showed marked increase in and deeper levels of higher-order thinking for two of the students. The other boy and girl showed progress using the inquiry activities, but it was not as evident. The social dynamics of the group seemed to hinder one girl's participation during some of the activities. The social interactions played a role in strengthening the exchange of ideas and thinking skills for the others. The teacher had a tremendous influence over the production of higher-level statements by modeling that level of thinking as she questioned the students. Through her practice of answering a question with a question, she gradually solicited more analytical thinking from her students.

OPEN DATA FOR DISCOVERY SCIENCE.

PubMed

Payne, Philip R O; Huang, Kun; Shah, Nigam H; Tenenbaum, Jessica

2017-01-01

The modern healthcare and life sciences ecosystem is moving towards an increasingly open and data-centric approach to discovery science. This evolving paradigm is predicated on a complex set of information needs related to our collective ability to share, discover, reuse, integrate, and analyze open biological, clinical, and population level data resources of varying composition, granularity, and syntactic or semantic consistency. Such an evolution is further impacted by a concomitant growth in the size of data sets that can and should be employed for both hypothesis discovery and testing. When such open data can be accessed and employed for discovery purposes, a broad spectrum of high impact end-points is made possible. These span the spectrum from identification of de novo biomarker complexes that can inform precision medicine, to the repositioning or repurposing of extant agents for new and cost-effective therapies, to the assessment of population level influences on disease and wellness. Of note, these types of uses of open data can be either primary, wherein open data is the substantive basis for inquiry, or secondary, wherein open data is used to augment or enrich project-specific or proprietary data that is not open in and of itself. This workshop is concerned with the key challenges, opportunities, and methodological best practices whereby open data can be used to drive the advancement of discovery science in all of the aforementioned capacities.

Assessing Dimensions of Inquiry Practice by Middle School Science Teachers Engaged in a Professional Development Program

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.

Open Adoption Placement by Birth Mothers in Their Twenties.

PubMed

Clutter, Lynn B

The purpose of this study was to summarize birth mothers' descriptions of unplanned pregnancy experienced in their twenties and how open adoption influenced their lives. Naturalistic inquiry was used with purposive sampling from one agency and telephone interviews of women who experienced unplanned pregnancy in their twenties and relinquishment through open adoption. Recorded, transcribed, and deidentified interviews were analyzed for qualitative themes. Fifteen participants judiciously weighed the open adoption decision. Over half parented other children prior to placement. Most knew they could not have parented this child due to life stressors. Placement was a hard decision, but ongoing contact with birth child and adoptive family was valued. Open adoption processes made them stronger by being happy that their child experienced family life with greater opportunities than birth mothers could offer at the time. Summarized themes used the acronym COMMITTED: C-care deeply about what is best for the child, O-ongoing open adoption: good and hard, M-meeting together regularly, M-moving on in personal growth, accomplishments, and milestones, I-independence from previous stressors or crises, T-transitions, T-therapeutic support, E-emotions, D-depression giving way to deepened strength and personal direction. Open adoption is reinforced as a positive resolution of unintended pregnancy for birth mothers in their twenties.

Colloquium: Non-Markovian dynamics in open quantum systems

NASA Astrophysics Data System (ADS)

Breuer, Heinz-Peter; Laine, Elsi-Mari; Piilo, Jyrki; Vacchini, Bassano

2016-04-01

The dynamical behavior of open quantum systems plays a key role in many applications of quantum mechanics, examples ranging from fundamental problems, such as the environment-induced decay of quantum coherence and relaxation in many-body systems, to applications in condensed matter theory, quantum transport, quantum chemistry, and quantum information. In close analogy to a classical Markovian stochastic process, the interaction of an open quantum system with a noisy environment is often modeled phenomenologically by means of a dynamical semigroup with a corresponding time-independent generator in Lindblad form, which describes a memoryless dynamics of the open system typically leading to an irreversible loss of characteristic quantum features. However, in many applications open systems exhibit pronounced memory effects and a revival of genuine quantum properties such as quantum coherence, correlations, and entanglement. Here recent theoretical results on the rich non-Markovian quantum dynamics of open systems are discussed, paying particular attention to the rigorous mathematical definition, to the physical interpretation and classification, as well as to the quantification of quantum memory effects. The general theory is illustrated by a series of physical examples. The analysis reveals that memory effects of the open system dynamics reflect characteristic features of the environment which opens a new perspective for applications, namely, to exploit a small open system as a quantum probe signifying nontrivial features of the environment it is interacting with. This Colloquium further explores the various physical sources of non-Markovian quantum dynamics, such as structured environmental spectral densities, nonlocal correlations between environmental degrees of freedom, and correlations in the initial system-environment state, in addition to developing schemes for their local detection. Recent experiments addressing the detection, quantification, and control of non-Markovian quantum dynamics are also briefly discussed.

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

NASA Astrophysics Data System (ADS)

Cooper, Susan J.

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

A3-2: Mindful Inquiry: From an Observer to a Gentle Change Agent in the Prevailing Culture of Do and Tell

PubMed Central

Tai-Seale, Ming

2014-01-01

Background/Aims In a culture of do and tell, researchers can use massive amount of EHR data, find statistically significant results, and publish them, often without the need to interact with the people who generated those data through their daily work or their use of health care services. Such observational inquiry can be informative one hand, as identifying areas for improvement requires the identification of gaps in quality of care or other shortcomings in the system. Mindful inquiry, i.e., asking questions in the moment, the here-and-now, on the other hand, has the potential to become a change agent that can facilitate the creation of new knowledge and the dissemination and implementation of best practices. Methods Appreciative inquiry. Results Task oriented culture of research values doing more than relating, telling more than asking, thereby leaving room for improvement in our capacity and desire to form and keep relationships with our research subjects or the organization where we do research. The practice of fly-by-night researcher who swoops down, collects data, publishes papers that expose dark sides of the subjects’ lived world has caused permanent harm to communities. Embedded researchers need to be mindful about the questions they raise, the methods they employ, and how they disseminate the results. Conclusions Embedded research is a series of complex, interdependent tasks which requires building positive, trusting relationships with research team and delivery system partners to facilitate good communication. We must be better at asking and do less at telling. Transform our mindset from the researcher knows a lot to the practitioners know a lot. We must be open to adaptive learning, be curious and courageous enough to ask questions to which we do not already know the answer. Good communication is key to building a trusting relationship which requires mindful inquiry, done with humility to build positive relationships with the delivery organization and guided by the wish to be of service to the greater good.

Approaches to Inquiry Teaching: Elementary teacher's perspectives

Ireland, Joseph; Watters, James J.; Lunn Brownlee, J.; Lupton, Mandy

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'.

Comparing Two Inquiry Professional Development Interventions in Science on Primary Students' Questioning and Other Inquiry Behaviours

NASA Astrophysics Data System (ADS)

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.

Adapting a successful inquiry-based immersion program to create an Authentic, Hands- on, Field based Curriculum in Environmental Science at Barnard College

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 as sampling, uncertainty, and variability, which are important to many fields. Many of the hands-on curricular activities have been adapted and used with a variety of student, teacher, and faculty groups. Faculty participants in our River Summer program (www.riversummer.org) see earth system science in a way that would be hard to replicate without the hands-on experience. Faculty participants are encouraged to adapt our activities to their own classroom. We are in the process of assembling many of our hands-on field-based activities as fully exportable curricular elements to further increase impacts.

A dialectical perspective on informed consent to treatment: an examination of radiologists' dilemmas and negotiations.

PubMed

Olufowote, James Olumide

2011-06-01

Informed consent to treatment (ICT), designed to honor patient autonomy, has been an important subject of inquiry in many disciplines. To foreground the dynamic and dilemmatic tendencies of ICT practice implied by previous inquiries, I advanced relational dialectics theory into the realm of physicians' experiences with ICT. On performing a dialectical analysis of transcripts from focus group discussions with radiologists, I found them experiencing four primary tensions: (a) between simple and complex ICT; (b) between radiologist and patient control; (c) between standardized and idiosyncratic practice (involving struggles between documentation and conversational process, and between vague and detailed language use); and (d) between withholding and disclosing alternatives. Moreover, I drew on concepts from relational dialectics theory to capture the various ways radiologists negotiate these dialectics. I conclude with practical applications for physician and patient training and interprofessional coordination.

Roles of Teachers in Orchestrating Learning in Elementary Science Classrooms

Zhai, Junqing; Tan, Aik-Ling

2015-12-01

This study delves into the different roles that elementary science teachers play in the classroom to orchestrate science learning opportunities for students. Examining the classroom practices of three elementary science teachers in Singapore, we found that teachers shuttle between four key roles in enabling student learning in science. Teachers can play the role of (1) dispenser of knowledge (giver), (2) mentor of learning (advisor), (3) monitor of students' activities (police), and (4) partner in inquiry (colearner). These roles are dynamic, and while teachers show a preference for one of the four roles, factors such as the nature of the task, the types of students, as well as the availability of time and resources affect the role that teachers adopt. The roles that teachers play in the classroom have implications for the practice of science as inquiry in the classroom as well as the identities that teachers and students form in the science learning process.

Girls on Ice: An Inquiry-Based Wilderness Science Education Program

NASA Astrophysics Data System (ADS)

Pettit, E. C.; Koppes, M. N.

2001-12-01

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.

ToxicDocs (www.ToxicDocs.org): from history buried in stacks of paper to open, searchable archives online.

As a result of a legal mechanism called discovery, the authors accumulated millions of internal corporate and trade association documents related to the introduction of new products and chemicals into workplaces and commerce. What did these private entities discuss among themselves and with their experts? The plethora of documents, both a blessing and a curse, opened new sources and interesting questions about corporate and regulatory histories. But they also posed an almost insurmountable challenge to historians. Thus emerged ToxicDocs, possible only with a technological innovation known as "Big Data." That refers to the sheer volume of new digital data and to the computational power to analyze them. Users will be able to identify what firms knew (or did not know) about the dangers of toxic substances in their products-and when. The database opens many areas to inquiry including environmental studies, business history, government regulation, and public policy. ToxicDocs will remain a resource free and open to all, anywhere in the world.

Mathematization of experience in a grade 8 open-inquiry environment: An introduction to the representational practices of science

Roth, Wolff-Michael; Bowen, G. Michael

The purpose of this classroom study was to investigate the use of mathematical representations in three Grade 8 general science classes that engaged in a 10-week open inquiry about the correlations between biological and physical variables in the environment. A constructivist perspective was used to design the study and to assemble the data sources. These data sources included videotapes of students in their work, audiotapes of teacher-student interactions and teacher interviews, the transcripts of these tapes, the students' field notebooks, field reports, special problem assignments, examinations, and the teachers' curriculum guides, field notes, and reflective journal. An interpretive method was used to construct assertions and the supporting data. In the setting provided, students increasingly used mathematical representations such as graphs and data tables to support their claims in a convincing manner; the use of abstract equations and percent calculations did not change over the course of the study. Representations such as graphs, maps, averages, and equations were not only useful as inscriptions (representations in some permanent medium, usually paper), but also as conscription devices in the construction of, and through which, students engaged each other to collaboratively construct meaning. This study demonstrates the use of representations as conscription devices, and illustrates how the use and understanding of inscriptions changes over time. Understanding representations as inscription and conscription devices focuses on the social aspects of knowing, which has important implications for teachers' conceptualization of learning and their organization of science classrooms.

John Dewey's Dual Theory of Inquiry and Its Value for the Creation of an Alternative Curriculum

2014-01-01

Dewey's theory of inquiry cannot be reduced to the pattern of inquiry common to both common-sense inquiry and scientific inquiry, which is grounded in the human life process, since such a reduction ignores Dewey's differentiation of the two forms of inquiry. The difference has to do with the focus of inquiry, with common-sense inquiry…

The roles of integration in molecular systems biology.

PubMed

O'Malley, Maureen A; Soyer, Orkun S

2012-03-01

A common way to think about scientific practice involves classifying it as hypothesis- or data-driven. We argue that although such distinctions might illuminate scientific practice very generally, they are not sufficient to understand the day-to-day dynamics of scientific activity and the development of programmes of research. One aspect of everyday scientific practice that is beginning to gain more attention is integration. This paper outlines what is meant by this term and how it has been discussed from scientific and philosophical points of view. We focus on methodological, data and explanatory integration, and show how they are connected. Then, using some examples from molecular systems biology, we will show how integration works in a range of inquiries to generate surprising insights and even new fields of research. From these examples we try to gain a broader perspective on integration in relation to the contexts of inquiry in which it is implemented. In today's environment of data-intensive large-scale science, integration has become both a practical and normative requirement with corresponding implications for meta-methodological accounts of scientific practice. We conclude with a discussion of why an understanding of integration and its dynamics is useful for philosophy of science and scientific practice in general. Copyright © 2011 Elsevier Ltd.

Being or Becoming: Toward an Open-System, Process-Centric Model of Personality.

PubMed

Giordano, Peter J

2015-12-01

Mainstream personality psychology in the West neglects the investigation of intra-individual process and variation, because it favors a Being over a Becoming ontology. A Being ontology privileges a structural (e.g., traits or selves) conception of personality. Structure-centric models in turn suggest nomothetic research strategies and the investigation of individual and group differences. This article argues for an open-system, process-centric understanding of personality anchored in an ontology of Becoming. A classical Confucian model of personality is offered as an example of a process-centric approach for investigating and appreciating within-person personality process and variation. Both quantitative and qualitative idiographic strategies can be used as methods of scientific inquiry, particularly the exploration of the Confucian exemplar of psychological health and well-being.

Developers often spend valuable time navigating and seeking relevant code in software maintenance. Currently, there is a lack of theoretical foundations to guide tool design and evaluation to best shape the code base to developers. This paper contributes a unified code navigation theory in light of the optimal food-foraging principles. We further develop a novel framework for automatically assessing the foraging mechanisms in the context of program investigation. We use the framework to examine to what extent the clustering of software entities affects code foraging. Our quantitative analysis of long-lived open-source projects suggests that clustering enriches the software environment and improves foraging efficiency. Our qualitative inquiry reveals concrete insights into real developer's behavior. Our research opens the avenue toward building a new set of ecologically valid code navigation tools.

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

NASA Astrophysics Data System (ADS)

Stone, Brian Andrew

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

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.

Alternative certification science teachers' understanding and implementation of inquiry-based instruction in their beginning years of teaching

NASA Astrophysics Data System (ADS)

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.

Fragile and Enduring Positive Affect: Implications for Adaptive Aging.

PubMed

Ong, Anthony D; Ram, Nilam

2017-01-01

There is robust evidence linking interindividual differences in positive affect (PA) with adaptive psychological and physical health outcomes. However, recent research has suggested that intraindividual variability or fluctuations in PA states over time may also be an important predictor of individual health outcomes. Here, we report on research that focuses on PA level and various forms of PA dynamics (variability, instability, inertia, and reactivity) in relation to health. PA level refers to the average level of positive feelings. In contrast, PA dynamics refer to short-term changes in PA that unfold over time. We discuss how consideration of both PA level and PA dynamics can provide a framework for reconciling when high PA is conducive or detrimental to health. We conclude that more work on PA dynamics is needed, especially in combination with PA level, and suggest productive questions for future inquiry in this area. © 2016 S. Karger AG, Basel.

Cultural unconscious in research: integrating multicultural and depth paradigms in qualitative research.

Culturally focused research has gained momentum in many disciplines, including psychology. However, much of this research fails to pay attention to the unconscious dynamics that underlie the study of culture and culturally influenced human beings. Such dynamics may be especially significant when issues of marginalization and oppression are present. Therefore, this paper seeks to contribute a framework for understanding cultural dynamics, especially unconscious cultural dynamics, within depth psychological qualitative research influenced by Jungian and post-Jungian scholarship. Inquiry that is approached with a commitment to making the unconscious conscious seeks to empower and liberate not only the subject/object studied but also the researchers themselves. Following a brief review of multiculturalism in the context of analytically informed psychology, this paper offers several case examples that focus on researchers' integration of awareness of the cultural unconscious in their study of cultural beings and topics. © 2016, The Society of Analytical Psychology.

Shifting more than the goal posts: developing classroom norms of inquiry-based learning in mathematics

NASA Astrophysics Data System (ADS)

Makar, Katie; Fielding-Wells, Jill

2018-03-01

The 3-year study described in this paper aims to create new knowledge about inquiry norms in primary mathematics classrooms. Mathematical inquiry addresses complex problems that contain ambiguities, yet classroom environments often do not adopt norms that promote curiosity, risk-taking and negotiation needed to productively engage with complex problems. Little is known about how teachers and students initiate, develop and maintain norms of mathematical inquiry in primary classrooms. The research question guiding this study is, "How do classroom norms develop that facilitate student learning in primary classrooms which practice mathematical inquiry?" The project will (1) analyse a video archive of inquiry lessons to identify signature practices that enhance productive classroom norms of mathematical inquiry and facilitate learning, (2) engage expert inquiry teachers to collaborate to identify and design strategies for assisting teachers to develop and sustain norms over time that are conducive to mathematical inquiry and (3) support and study teachers new to mathematical inquiry adopting these practices in their classrooms. Anticipated outcomes include identification and illustration of classroom norms of mathematical inquiry, signature practices linked to these norms and case studies of primary teachers' progressive development of classroom norms of mathematical inquiry and how they facilitate learning.

The impact of a professional development model on middle school science teachers' efficacy and implementation of inquiry

Lotter, Christine; Smiley, Whitney; Thompson, Stephen; Dickenson, Tammiee

2016-12-01

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.

The aim of the research was to identify and develop midwives' skills to support women with mental health needs during pregnancy, using an action research approach. A review of perinatal mental health services in a large Dublin maternity unit revealed a high number of referred women who 'did not attend' the perinatal mental health service with few guidelines in place to support midwives in identifying and referring women for specialist help. Action research using cooperative inquiry involved a mental health nurse specialist and a team of midwives, who were drawn to each other in mutual concern about an area of practice. Data were gathered from three Cooperative Inquiry meetings, which incorporated one main Action Research Cycle of constructing, planning, taking and evaluating action. Data were analysed using a thematic content analysis framework. Participants experienced varying levels of uncertainty about how to support women with perinatal mental health needs. Cooperative inquiry supported participants in making sense of how they understood perinatal mental health and how they managed challenges experienced when caring for women with perinatal mental health issues. Participants developed a referral pathway, highlighted the significance of education to support women with perinatal mental health issues and identified the value of using open questions to promote conversation with pregnant women about mental health. Midwives value education and support to identify and refer women at risk of perinatal mental health issues. Cooperative inquiry, with a focus on action and shared reflection, facilitated the drawing together of two professional groups with diverse knowledge bases to work together to develop practice in an area of mutual concern. Perinatal mental health is a significant public health issue and midwives need support to make psychosocial assessments and to negotiate access to specialist services where available and when required. © 2017 John Wiley & Sons Ltd.

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 in inquiry investigations, the relationship of scientific inquiry to the nature of science, whether the process of scientific inquiry follows the traditional scientific method, and the similarities and differences in conceptualizations of scientific inquiry across science disciplines. These findings represent a private side of science, which can be useful in characterizing key features of scientific inquiry to be incorporated into K--16 teaching practices.

Inquiry science as a discourse: New challenges for teachers, students, and the design of curriculum materials

NASA Astrophysics Data System (ADS)

Tzou, Carrie Teh-Li

Science education reform emphasizes learning science through inquiry as a way to engage students in the processes of science at the same time that they learn scientific concepts. However, inquiry involves practices that are challenging for students because they have underlying norms with which students may be unfamiliar. We therefore cannot expect students to know how to engage in such practices simply by giving them opportunities to do so, especially if the norms for inquiry practices violate traditional classroom norms for engaging with scientific ideas. Teachers therefore play a key role in communicating expectations for inquiry. In this dissertation, I present an analytical framework for characterizing two teachers' enactments of an inquiry curriculum. This framework, based on Gee's (1996) notion of Discourses, describes inquiry practices in terms of three dimensions: cognitive, social, and linguistic. I argue that each of these dimensions presents challenges to students and, therefore, sites at which teachers' support is important for students' participation in inquiry practices. I use this framework to analyze two teachers' support of inquiry practices as they enact an inquiry-based curriculum. I explore three questions in my study: (1) what is the nature of teachers' support of inquiry practices? (2) how do teachers accomplish goals along multiple dimensions of inquiry?, and (3) what aspects of inquiry are in tension and how can we describe teachers' practice in terms of the tradeoff spaces between elements of inquiry in tension? In order to study these questions, I studied two eighth grade teachers who both enacted the same inquiry-based science curriculum developed by me and others in the context of a large design-based research project called IQWST (Investigating and Questioning my World through Science and Technology. I found that the teachers provided support for inquiry along all three dimensions, sometimes in ways in which the dimensions were synergistic and sometimes in ways in which the dimensions were in tension. These findings have implications for the design of inquiry science learning environments and for our understanding of what it means for teachers to be "cultural brokers" between students' everyday experiences and classroom science inquiry.

A platform for dynamic simulation and control of movement based on OpenSim and MATLAB.

Numerical simulations play an important role in solving complex engineering problems and have the potential to revolutionize medical decision making and treatment strategies. In this paper, we combine the rapid model-based design, control systems and powerful numerical method strengths of MATLAB/Simulink with the simulation and human movement dynamics strengths of OpenSim by developing a new interface between the two software tools. OpenSim is integrated with Simulink using the MATLAB S-function mechanism, and the interface is demonstrated using both open-loop and closed-loop control systems. While the open-loop system uses MATLAB/Simulink to separately reproduce the OpenSim Forward Dynamics Tool, the closed-loop system adds the unique feature of feedback control to OpenSim, which is necessary for most human movement simulations. An arm model example was successfully used in both open-loop and closed-loop cases. For the open-loop case, the simulation reproduced results from the OpenSim Forward Dynamics Tool with root mean square (RMS) differences of 0.03° for the shoulder elevation angle and 0.06° for the elbow flexion angle. MATLAB's variable step-size integrator reduced the time required to generate the forward dynamic simulation from 7.1s (OpenSim) to 2.9s (MATLAB). For the closed-loop case, a proportional-integral-derivative controller was used to successfully balance a pole on model's hand despite random force disturbances on the pole. The new interface presented here not only integrates the OpenSim and MATLAB/Simulink software tools, but also will allow neuroscientists, physiologists, biomechanists, and physical therapists to adapt and generate new solutions as treatments for musculoskeletal conditions.

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 more frequent use of inquiry in their classrooms.

All-digital signal-processing open-loop fiber-optic gyroscope with enlarged dynamic range.

We propose and realize a new open-loop fiber-optic gyroscope (FOG) with an all-digital signal-processing (DSP) system where an all-digital phase-locked loop is employed for digital demodulation to eliminate the variation of the source intensity and suppress the bias drift. A Sagnac phase-shift tracking method is proposed to enlarge the dynamic range, and, with its aid, a new open-loop FOG, which can achieve a large dynamic range and high sensitivity at the same time, is realized. The experimental results show that compared with the conventional open-loop FOG with the same fiber coil and optical devices, the proposed FOG reduces the bias instability from 0.259 to 0.018 deg/h, and the angle random walk from 0.031 to 0.006 deg/h(1/2), moreover, enlarges the dynamic range to ±360 deg/s, exceeding the maximum dynamic range ±63 deg/s of the conventional open-loop FOG.

From trace evidence to bioinformatics: putting bryophytes into molecular biology education.

PubMed

Fuselier, Linda; Bougary, Azhar; Malott, Michelle

2011-01-01

Students benefit most from their science education when they participate fully in the process of science in the context of real-world problems. We describe a student-directed open-inquiry lab experience that has no predetermined outcomes and requires students to engage in all components of scientific inquiry from posing a question through evaluating and reporting results. Over 5 weeks, students learn how bryophytes are used in forensics and become proficient in important molecular biology lab skills including DNA isolation, polymerase chain reaction, gel electrophoresis, capillary electrophoresis, and genotyping. For this portion of the experience, there is no specialized equipment necessary outside of gel electrophoresis supplies and a thermocycler. In an optional extension of the experience, students sequence a plastid intron and use introductory bioinformatics skills to identify species related to their forensics case. Students who participated in the lab experience performed well on content-based assessment, and student attitudes toward the experience were positive and indicative of engaged learning. The lab experience is easily modified for higher or lower level courses and can be used in secondary education. Copyright © 2011 Wiley Periodicals, Inc.

Nonlinear dynamics and damage induced properties of soft matter with application in oncology

NASA Astrophysics Data System (ADS)

Naimark, O.

2017-09-01

Molecular-morphological signs of oncogenesis could be linked to multiscale collective effects in molecular, cell and tissue related to defects (damage) dynamics. It was shown that nonlinear behavior of biological systems can be linked to the existence of characteristic collective open state modes providing the coherent expression dynamics. New type of criticality in nonequilibrium systems with defects—structural-scaling transition allows the definition of the `driving force' for a biological soft matter related to consolidated open states. The set of collective open states (breathers, autosolitons and blow-up modes) in the molecular ensembles provides the collective expression dynamics to attract the entire system (cell, tissue) toward a few preferred global states. The co-existence of three types of collective modes determines the multifractal scenario of biological soft matter dynamics. The appearance of `globally convergent' dynamics corresponding to the coherent behavior of multiscale blow-up open states (blow-up gene expression) leads to anomalous localized softening (blow-up localized damage) and the subjection of the cells (or tissue) to monofractal dynamics. This dynamics can be associated with cancer progression.

2018-06-01

We introduce a classification scheme for the generators of bosonic open Gaussian dynamics, providing instructive diagrams description for each type of dynamics. Using this classification, we discuss the consequences of imposing complete positivity on Gaussian dynamics. In particular, we show that non-symplectic operations must be active to allow for complete positivity. In addition, non-symplectic operations can, in fact, conserve the volume of phase space only if the restriction of complete positivity is lifted. We then discuss the implications for the relationship between information and energy flows in open quantum mechanics.

Fixation, transient landscape, and diffusion dilemma in stochastic evolutionary game dynamics

NASA Astrophysics Data System (ADS)

Zhou, Da; Qian, Hong

2011-09-01

Agent-based stochastic models for finite populations have recently received much attention in the game theory of evolutionary dynamics. Both the ultimate fixation and the pre-fixation transient behavior are important to a full understanding of the dynamics. In this paper, we study the transient dynamics of the well-mixed Moran process through constructing a landscape function. It is shown that the landscape playing a central theoretical “device” that integrates several lines of inquiries: the stable behavior of the replicator dynamics, the long-time fixation, and continuous diffusion approximation associated with asymptotically large population. Several issues relating to the transient dynamics are discussed: (i) multiple time scales phenomenon associated with intra- and inter-attractoral dynamics; (ii) discontinuous transition in stochastically stationary process akin to Maxwell construction in equilibrium statistical physics; and (iii) the dilemma diffusion approximation facing as a continuous approximation of the discrete evolutionary dynamics. It is found that rare events with exponentially small probabilities, corresponding to the uphill movements and barrier crossing in the landscape with multiple wells that are made possible by strong nonlinear dynamics, plays an important role in understanding the origin of the complexity in evolutionary, nonlinear biological systems.

Undergraduate honors students' images of science: Nature of scientific work and scientific knowledge

NASA Astrophysics Data System (ADS)

Wallace, Michael L.

This exploratory study assessed the influence of an implicit, inquiry-oriented nature of science (NOS) instructional approach undertaken in an interdisciplinary college science course on undergraduate honor students' (UHS) understanding of the aspects of NOS for scientific work and scientific knowledge. In this study, the nature of scientific work concentrated upon the delineation of science from pseudoscience and the value scientists place on reproducibility. The nature of scientific knowledge concentrated upon how UHS view scientific theories and how they believe scientists utilize scientific theories in their research. The 39 UHS who participated in the study were non-science majors enrolled in a Honors College sponsored interdisciplinary science course where the instructors took an implicit NOS instructional approach. An open-ended assessment instrument, the UFO Scenario, was designed for the course and used to assess UHS' images of science at the beginning and end of the semester. The mixed-design study employed both qualitative and quantitative techniques to analyze the open-ended responses. The qualitative techniques of open and axial coding were utilized to find recurring themes within UHS' responses. McNemar's chi-square test for two dependent samples was used to identify whether any statistically significant changes occurred within responses from the beginning to the end of the semester. At the start of the study, the majority of UHS held mixed NOS views, but were able to accurately define what a scientific theory is and explicate how scientists utilize theories within scientific research. Postinstruction assessment indicated that UHS did not make significant gains in their understanding of the nature of scientific work or scientific knowledge and their overall images of science remained static. The results of the present study found implicit NOS instruction even with an extensive inquiry-oriented component was an ineffective approach for modifying UHS' images of science towards a more informed view of NOS.

Using a theoretical perspective of communities of practice, this case study examines a prospective chemistry teacher's inquiry-based teaching during his practicum. Conrad was a former student of an inquiry-oriented science course, Inquiry Empowering Technologies (IET). The research questions were (a) How did Conrad translate the IET inquiry practices during his practicum?; (b) How did the mentor teacher shape Conrad's participation?; (c) In what ways did Conrad negotiate new meanings of inquiry as a result of his practicum? Interview transcripts were the primary data source. Conrad carried many of the IET inquiry practices into his practicum. He equated inquiry with the use of evidence and had students create evidence-based explanations for how soap works. He chose not to incorporate the tentative nature of science. Although traditional in his own teaching, the mentor teacher supported Conrad by allowing him to teach through inquiry and by removing time constraints. As a result of his practicum, Conrad negotiated new meanings of inquiry teaching and developed an expanded view of technology. Conrad believed that high school students needed guidance when engaging in inquiry and that the tentative nature of science does not transfer to secondary chemistry. Implications for theory and practice are given.

Curricular reform and inquiry teaching in biology: where are our efforts most fruitfully invested?

PubMed

Timmerman, Briana E; Strickland, Denise C; Carstensen, Susan M

2008-08-01

University faculty often express frustration with the accuracy of students' understanding of science in general and of evolution in particular. A rich research literature suggests that inquiry-based pedagogies are more effective in producing meaningful learning than are traditional, didactic approaches. A pragmatic investigation into the efficacy of inquiry-based curricular reforms compared to traditional laboratory activities was undertaken in the introductory biology course for majors at a large state university in the southeastern United States. The topics of the course focused on biodiversity, evolution, and plant and animal anatomy and physiology. Students' learning in the inquiry versus traditional units was compared using both a test of pre-post content knowledge as well as open-ended written responses in which students described events in which there was meaningful learning and conceptual changes. The pre-post tests were replicated over five semesters of the same course (n = 1493 students). Students' misconceptions as well as examples of meaningful learning were gathered for two semesters in the same course (n = 518 students). Results consistently revealed that descriptive, concrete topics such as anatomy can be taught effectively using traditional didactic methods; average effect sizes (a measure of the difference between pretest scores and posttest scores) range from 1.8 to 2.1. The inquiry units also increased knowledge of content on the topics of evolution and biodiversity by a significant degree (average effect sizes range from 1.0 to 1.1), despite the fact that students spent less than half the instructional time on these units compared to the didactic units. In addition, a literature review indicated that highly abstract or mathematical concepts such as evolution or geologic time require greater formal reasoning ability and that students often show lesser gains in these areas compared to more concrete topics. It was therefore especially notable that the frequency of meaningful learning events was significantly higher in the units on evolution compared to the traditional units (χ(2) P < 0.5 to 0.001). A catalog of students' misconceptions (some of which were quite unexpected) was also generated and found useful for future teaching. Therefore, we feel that when time and resources for curricular reform are limited, those efforts should prioritize abstract and foundational topics such as evolution. Didactic teaching appears sufficient for more concrete topics such as anatomy.

The agenda for theory and research in the field of leadership studies has evolved over the last 100 years from focuses on the internal dispositions associated with effective leaders to broader inquiries that include emphases on the cognitions, attributes, behaviors, and contexts in which leaders and followers are dynamically embedded and interact over time. Leadership theory and research has reached a point in its development at which it needs to move to the next level of integration--considering the dynamic interplay between leaders and followers, taking into account the prior, current, and emerging context--for continued progress to be made in advancing both the science and practice of leadership.

The nature, meanings, and dynamics of lived experiences of a person with syringomyelia: a phenomenological study.

PubMed

Hilton, Edith L; Henderson, Lesley J

2003-01-01

Syringomyelia, considered a rare neurological disease, is relatively uninvestigated in the nursing literature. The aims of this qualitative phenomenological case study were to discover the nature, meanings, and dynamics of lived experiences of a 52-year-old Caucasian male with syringomyelia. Using van Manen's Method of Phenomenological inquiry (van Manen, 1990), data were collected, checked, and analyzed according to the philosophy, approach, and methodological procedures of phenomenology. Findings revealed an overarching theme of engulfment by disease. Essential themes included loss of abilities, struggles to adapt to changes, and life as a person who was disabled. Eleven sub-themes were also identified. Implications for nursing practice are discussed.

Does the Discussion of Socio-Scientific Issues require a Paradigm Shift in Science Teachers' Thinking?

NASA Astrophysics Data System (ADS)

Day, Stephen P.; Bryce, Tom G. K.

2011-08-01

The purpose of this study was to characterise secondary school science teachers' conceptual models of discussion, against the background that a number of researchers have found that discussion of socio-scientific issues in science classrooms is rare, somewhat discomforting for teachers and its purpose unclear. Recent research indicates that when science teachers do engage in socio-scientific discussion, the quality is poor and is teacher-centred where pupils' views do not figure prominently (far less be clarified and integrated with their scientific learning). This has led to calls for such dialogue to be conducted by humanities teachers. The question arising from such thinking is: Do science teachers hold different conceptual models of discussion from their humanities colleagues? Using semi-structured interviews, three groups each of six teachers (experienced science teachers, experienced humanities teachers, and newly qualified science teachers) were interviewed in-depth in order to characterise their conceptual understanding of discussion as a teaching strategy. Analysis of the interview transcripts utilised the constant comparison approach of grounded theory. Five conceptual models of discussion emerged from an analysis of the data-discussion: (1) as a teacher-mediated discourse; (2) as open-ended inquiry; (3) for the development of reasoning skills; (4) as mediated transfer of knowledge to real-life contexts; and (5) as practice for democratic citizenship. The results confirmed that the science teachers' emphasis tended to stress practice for democratic citizenship whereas the humanities teachers' emphasis was more towards open-ended inquiry and for the development of reasoning skills.

Price limit trading rules are useful to cool off traders short-term trading mania on individual stocks. The price dynamics approaching the limit boards are known as the magnet effect. However, the price dynamics after opening price limit hits are not well investigated. Here, we provide a detailed analysis on the price dynamics after the hits of up-limit or down-limit is open based on all A-share stocks traded in the Chinese stock markets. A "W" shape is found in the expected return, which reveals high probability of a continuous price limit hit on the following day. We also find that price dynamics after opening limit hits are dependent on the market trends. The time span of continuously hitting the price limit is found to an influence factor of the expected profit after the limit hit is open. Our analysis provides a better understanding of the price dynamics around the limit boards and contributes potential practical values for investors.

Designing non-Hermitian dynamics for conservative state evolution on the Bloch sphere

NASA Astrophysics Data System (ADS)

Yu, Sunkyu; Piao, Xianji; Park, Namkyoo

2018-03-01

An evolution on the Bloch sphere is the fundamental state transition, including optical polarization controls and qubit operations. Conventional evolution of a polarization state or qubit is implemented within a closed system that automatically satisfies energy conservation from the Hermitian formalism. Although particular forms of static non-Hermitian Hamiltonians, such as parity-time-symmetric Hamiltonians, allow conservative states in an open system, the criteria for the energy conservation in a dynamical open system have not been fully explored. Here, we derive the condition of conservative state evolution in open-system dynamics and its inverse design method, by developing the non-Hermitian modification of the Larmor precession equation. We show that the geometrically designed locus on the Bloch sphere can be realized by different forms of dynamics, leading to the isolocus family of non-Hermitian dynamics. This increased degree of freedom allows the complementary phenomena of error-robust and highly sensitive evolutions on the Bloch sphere, which could be applicable to stable polarizers, quantum gates, and optimized sensors in dynamical open systems.

University of North Carolina Health Care System Drug Information Center. Provider inquiries and responses were extracted and characterized by indication for treatment and reason for inquiry. Comparison of the first and second 5-year periods was performed to delineate trends. Descriptive statistics, Fisher's Exact and χ2 tests were used for analysis. Inquiry origin, time, and subject. 433 inquiries were retrieved over the study period from physicians (50%), pharmacists (21%), and nurses (18%). Inquiries were most often made during the antepartum period (34%), followed by the postpartum (28%) and preconception (22%) periods. The most frequent indications for inquiry were psychiatry (15%) and infectious diseases (14%), which remained constant throughout the study period. Safety was the most common reason for inquiry (52%). The responses provided to callers were limited due to lack of information availability 37% of the time. Psychiatry and infectious disease-related indications are the most frequent subjects of provider inquiry regarding medication use in pregnancy. Rates of inquiry remained constant throughout the past decade in most therapeutic areas. These findings are consistent with previous observations in other developed countries and suggest high-yield areas for pharmacist education.

The implementation of the inquiry laboratory based project to enhance scientific inquiry literacy of prospective biology teachers in Microbiology course has been done. 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.

Professional development, practice, and teacher discourse communities: How an urban high school science teacher negotiated inquiry practice

NASA Astrophysics Data System (ADS)

Deneroff, Victoria Matzenauer

This is an ethnographic case study of one urban high school science teacher who was attempting to use inquiry-based teaching in her practice. Rather than focusing on pedagogy, the study examines the social networks and communities of practice in which Marie Gonzalez participated. I make the argument that science teaching is a Discourse (Gee, 1990), and that teaching inquiry science means constructing an identity as a participant in what I call the Discourse of Inquiry. I also use discourse analysis to tease out a Discourse of Traditional Science Teaching. I conclude that the Traditional and Inquiry Discourses mediate a teacher's ideas of what it means to teach, and that, while Inquiry teachers are "bilingual", that is, able to participate in both Discourses, Traditional teachers are deaf to the Discourse of Inquiry. Moreover, in my study there is convincing evidence that administrators charged with evaluation were also unfamiliar with the Discourse of Inquiry and were therefore unable to provide support for Marie's inquiry practice. In light of these findings, it is not at all surprising that Marie found it quite difficult to use inquiry-based pedagogy. In order for teachers to adopt discourse-based reforms such as inquiry, the Discourse must be available to teachers in their workplaces.

An analysis of elementary teachers' perceptions of teaching science as inquiry

NASA Astrophysics Data System (ADS)

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 of teaching science as inquiry. This study suggests that elementary teachers might benefit from increased and sustained professional development programs centered on inquiry teaching strategies. Professional development activities on teaching science as inquiry create opportunities for teachers to confront and develop ways of thinking about inquiry and ultimately enhance inquiry-based teaching in their classrooms.

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.

Lid dynamics of porcine pancreatic lipase in non-aqueous solvents.

PubMed

Haque, Neshatul; Prabhu, N Prakash

2016-10-01

Understanding the dynamics of enzymes in organic solvents has wider implications on their industrial applications. Pancreatic lipases, which show activity in their lid open-state, demonstrate enhanced activity in organic solvents at higher temperatures. However, the lid dynamics of pancreatic lipases in non-aqueous environment is yet to be clearly understood. Dynamics of porcine pancreatic lipase (PPL) in open and closed conformations was followed in ethanol, toluene, and octanol using molecular simulation methods. In silico double mutant D250V and E254L of PPL (PPLmut-Cl) was created and its lid opening dynamics in water and in octanol was analyzed. PPL showed increase in solvent accessible surface area and decrease in packing density as the polarity of the surrounded solvent decreased. Breaking the interactions between D250-Y115, and D250-E254 in PPLmut-Cl directed the lid to attain open-state conformation. Major energy barriers during the lid movement in water and in octanol were identified. Also, the trajectories of lid movement were found to be different in these solvents. Only the double mutant at higher temperature showed lid opening movement suggesting the essential role of the three residues in holding the lid in closed conformation. The lid opening dynamics was faster in octanol than water suggesting that non-polar solvents favor open conformation of the lid. This study identifies important interactions between the lid and the residues in domain 1 which possibly keeps the lid in closed conformation. Also, it explains the rearrangements of residue-residue interactions during lid opening movement in water and in octanol. Copyright © 2016 Elsevier B.V. All rights reserved.

A compositional framework for reaction networks

NASA Astrophysics Data System (ADS)

Baez, John C.; Pollard, Blake S.

Reaction networks, or equivalently Petri nets, are a general framework for describing processes in which entities of various kinds interact and turn into other entities. In chemistry, where the reactions are assigned ‘rate constants’, any reaction network gives rise to a nonlinear dynamical system called its ‘rate equation’. Here we generalize these ideas to ‘open’ reaction networks, which allow entities to flow in and out at certain designated inputs and outputs. We treat open reaction networks as morphisms in a category. Composing two such morphisms connects the outputs of the first to the inputs of the second. We construct a functor sending any open reaction network to its corresponding ‘open dynamical system’. This provides a compositional framework for studying the dynamics of reaction networks. We then turn to statics: that is, steady state solutions of open dynamical systems. We construct a ‘black-boxing’ functor that sends any open dynamical system to the relation that it imposes between input and output variables in steady states. This extends our earlier work on black-boxing for Markov processes.

Promoting Learning by Inquiry Among Undergraduates in Soil Sciences: Scaffolding From Project-based Courses to Student-Staff Research Grants by the National Research Agency in Oman

Al-Ismaily, Said; Kacimov, Anvar; Al-Maktoumi, Ali

2016-04-01

Three strategies in a soil science undergraduate programme with inquiry-based learning (IBL) principles at Sultan Qaboos University, Oman, are presented. The first strategy scaffolds courses into three phases: with direct instructional guidance, structured IBL, and finally, guided to open IBL. The second strategy involves extra-curricular activities of undergraduates, viz. conducting workshops on soils for pupils in grades 7-9 with their teachers. The third strategy promotes the teaching-research nexus through collaboration between the undergraduates and faculty within a student-supporting, government-funded programme through 1-year long research grants of up to 5,500 US/project. The efficiency of the strategies was evaluated by students' evaluations of courses and instructors and questionnaire-based surveys. Statistics of students' responses in teaching evaluations of IBL courses showed a significantly higher level of satisfaction compared with regular courses taught in the department and college. In surveys of other constituencies of the program, viz. the secondary schools, more than 90% of respondents "agreed" or "strongly agreed" that they had learned new information/secrets about soils. The indicators of success in the third strategy are: winning a highly competitive grant and, moreover, earning an even more competitive annual national award for the best executed research project. The two top graduates of the IBL soil programme progressed into the MSc programme with the university and national scholarships. Key words: inquiry based learning, soil science undergraduate program, scaffold of courses, outreach activities, teaching-research nexus, evaluation of program's efficiency

Increasing parental involvement is vital in supporting student academic achievement and social growth. The purpose of this emergent phenomenological study was to identify conditions required to successfully construct a supportive learning environment to form partnerships between students, parents, and educators. The overall research question in this study investigated the conditions necessary to successfully enlist parental participation with students during science inquiry investigations at the secondary school level. One hundred thirteen pairs of parents and students engaged in a 6-week scientific inquiry activity and recorded attitudinal data in dialogue journals, questionnaires, open-ended surveys, and during one-one-one interviews conducted by the researcher between individual parents and students. Comparisons and cross-interpretations of inter-rater, codified, triangulated data were utilized for identifying emergent themes. Data analysis revealed the active involvement of parents in researching with their child during inquiry investigations, engaging in journaling, and assessing student performance fostered partnerships among students, parents, and educators and supported students' social skills development. The resulting model, employing constructivist leadership and enlisting parent involvement, provides conditions and strategies required to develop a community of practice that can help effect social change. The active involvement of parents fostered improved efficacy and a holistic mindset to develop in parents, students, and teachers. Based on these findings, the interactive collaboration of parents in science learning activities can proactively facilitate a community of practice that will assist educators in facilitating social change.

Memory Effects and Nonequilibrium Correlations in the Dynamics of Open Quantum Systems

We propose a systematic approach to the dynamics of open quantum systems in the framework of Zubarev's nonequilibrium statistical operator method. The approach is based on the relation between ensemble means of the Hubbard operators and the matrix elements of the reduced statistical operator of an open quantum system. This key relation allows deriving master equations for open systems following a scheme conceptually identical to the scheme used to derive kinetic equations for distribution functions. The advantage of the proposed formalism is that some relevant dynamical correlations between an open system and its environment can be taken into account. To illustrate the method, we derive a non-Markovian master equation containing the contribution of nonequilibrium correlations associated with energy conservation.

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.

An examination of how middle school science teachers conduct collaborative inquiry and reflection about students' conceptual understanding

Todd-Gibson, Christine

This qualitative case study examined how middle school science teachers conducted collaborative inquiry and reflection about students' conceptual understanding, and how individual teachers in the middle school science group acted and made reflections in response to their collaborative inquiry. It also examined external influences that affected the teachers' ability to engage in collaborative inquiry. Observational, written, and interview data were collected from observations of teachers' face-to-face meetings and reflections, individual interviews, a focus group interview, and online reflections. The results of this study revealed that collaborative inquiry is a form of professional development that includes answering curricular questions through observation, communication, action, and reflection. This approach was developed and implemented by middle school science teachers. The premise of an inquiry is based on a need with students. Middle school science teachers came to consensus about actions to affect students' conceptual understanding, took action as stated, and shared their reflections of the actions taken with consideration to current and upcoming school activities. Activities involved teachers brainstorming and sharing with one another, talking about how the variables were merged into their curriculum, and how they impacted students' conceptual understanding. Teachers valued talking with one another about science content and pedagogy, but did find the inquiry portion of the approach to require more development. The greatest challenge to conducting collaborative inquiry and reflection was embedding teacher inquiry within a prescribed inquiry that was already being conducted by the Sundown School District. Collaborative inquiry should be structured so that it meets the needs of teachers in order to attend to the needs of students. A conducive atmosphere for collaborative inquiry and reflection is one in which administrators make the process mandatory and facilitate the process by removing an existing inquiry.

The term "inquiry" covers the large spectrum of what people are currently doing in the nascent field of simulation. This monograph proposes appropriate means of dissemination for the many different levels of inquiry that may arise from the Summit or other sources of inspiration. We discuss various methods of inquiry and where they might fit in the hierarchy of reporting and dissemination. We provide guidance for deciding whether an inquiry has reached the level of development required for publication in a peer-reviewed journal and conclude with a discussion of what most journals view as inquiry acceptable for publication.

Time series estimation techniques are usually employed in biomedical research to derive variables less accessible from a set of related and more accessible variables. These techniques are traditionally built from systems modeling approaches including simulation, blind decovolution, and state estimation. In this work, we define target time series (TTS) and its related time series (RTS) as the output and input of a time series estimation process, respectively. We then propose a novel data mining framework for time series estimation when TTS and RTS represent different sets of observed variables from the same dynamic system. This is made possible by mining a database of instances of TTS, its simultaneously recorded RTS, and the input/output dynamic models between them. The key mining strategy is to formulate a mapping function for each TTS-RTS pair in the database that translates a feature vector extracted from RTS to the dissimilarity between true TTS and its estimate from the dynamic model associated with the same TTS-RTS pair. At run time, a feature vector is extracted from an inquiry RTS and supplied to the mapping function associated with each TTS-RTS pair to calculate a dissimilarity measure. An optimal TTS-RTS pair is then selected by analyzing these dissimilarity measures. The associated input/output model of the selected TTS-RTS pair is then used to simulate the TTS given the inquiry RTS as an input. An exemplary implementation was built to address a biomedical problem of noninvasive intracranial pressure assessment. The performance of the proposed method was superior to that of a simple training-free approach of finding the optimal TTS-RTS pair by a conventional similarity-based search on RTS features. 2009 Elsevier Inc.

Kostenbader, Tracy C.

Due to the logistics of guided-inquiry lesson, students learn to problem solve and develop critical thinking skills. This mixed-methods study analyzed the students' attitudes towards science during inquiry lessons. My quantitative results from a repeated measures survey showed no significant difference between student attitudes when taught with either structured-inquiry or guided-inquiry lessons. The qualitative results analyzed through a constant-comparative method did show that students generate positive interest, critical thinking and low level stress during guided-inquiry lessons. The qualitative research also gave insight into a teacher's transition to guided-inquiry. This study showed that with my students, their attitudes did not change during this transition according to the qualitative data however, the qualitative data did how high levels of excitement. The results imply that students like guided-inquiry laboratories, even though they require more work, just as much as they like traditional laboratories with less work and less opportunity for creativity.

Kindergarten Teachers' Understanding of the Elements of Implementing Inquiry-Based Science Instruction

Blevins, Kathryn

The purpose of this basic qualitative research study was to identify the extent to which kindergarten teachers understand and implement inquiry-based instruction in their science classrooms. This study was conducted in response to the indication that traditional didactic teaching methods were not enough to adequately prepare American students to compete in the global economy. Inquiry is a teaching method that could prepare students for the critical thinking skills needed to enter society in the 21st century. It is vital that teachers be sufficiently trained in teaching using the necessary components of inquiry-based instruction. This study could be used to inform leaders in educational administration of the gaps in teachers' understanding as it pertains to inquiry, thus allowing for the delivery of professional development that will address teachers' needs. Existing literature on inquiry-based instruction provides minimal information on kindergarten teachers' understanding and usage of inquiry to teach science content, and this information would be necessary to inform administrators in their response to supporting teachers in the implementation of inquiry. The primary research question for this study was "To what extent do kindergarten teachers understand the elements of implementing inquiry-based lessons in science instruction?" The 10 participants in this study were all kindergarten teachers in a midsized school district in the Mid-Atlantic region of the United States. Data were collected using face-to-face semistructured interviews, observations of the teachers implementing what they perceived to be inquiry-based instruction, and the analysis of lesson plans to indicate the components used to plan for inquiry-instruction. The findings of this study indicated that while teachers believed inquiry to be a beneficial method for teaching science, they did not understand the components of inquiry and tended to implement lesson plans created at the district level. By analyzing the findings of this study, it became evident that kindergarten teachers could benefit from scaffolded, ongoing professional development focusing on the components of inquiry and how to implement inquiry in their science instruction.
