Analysis of Student Work to Develop Teacher Knowledge of Inquiry Science Erin Peters, M.Ed., NBCT Doctoral Student in Science Education
Purpose of Study Qualitative Study embedded in 5-year Design-Based Research project • Discover teachers’ perceptions about understanding inquiry science • Discover teachers perceptions about how inquiry happens in 4th grade science classrooms • Explore alignment of teacher conceptual frameworks of inquiry science with classroom practices and with ideal models of inquiry
Conceptual Context of Research • Study developed from an interest in patterns expressed in reflections of student work studies revealing increased understanding of inquiry • Researcher’s initial model of inquiry was inadequate in the analysis phase of research • A reformed model of inquiry was developed from background literature and helped to inform the analysis phase of research
Student Work Analysis Components • Teacher Information Worksheet • Framework and rationale for lesson • Questions to Facilitate Discussion • Guided peer review to inquiry-based instruction • Student Work Samples • Work that exceeds expectations, meets expectations and does not meet expectation • Teacher Reflection
Researcher’s Initial Model of Science Inquiry Enacting the features of process science • Observing • Inferring • Concluding • Estimating • Controlling variables • Organizing data • Classifying
Researcher’s Refined Model of Science Inquiry Includes features that make science valuable and unique as a discipline • Nature follows rules and patterns which are understandable • Models are useful as representations, but must be evaluated for weaknesses • Claims are supported by evidence • Scientific knowledge can be applied universally and is sometimes subject to change • Explanations about science come partly from observations and partly from ideas • (Benchmarks, 1996)

Research Questions Research Focus: • What are teacher perceptions of inquiry at the beginning and mid-point of a graduate course involving intensive exploration of science inquiry? • What are teacher perceptions about how inquiry happens in a 4th grade science classroom? • How do teachers’ perceptions of inquiry compare with their perceptions of how inquiry happens in the classroom? • How do teacher conceptions of inquiry compare with the researcher’s initial and refined models of inquiry?
Background Literature • Investigation into experienced science teachers’ beliefs about inquiry • Provides keys in understanding which belief conditions may be more apt to adopt inquiry-based lessons • (Wallace & Kang, 2004) • High school teachers’ decision making models for planning and teaching science • Decisions are dominated by considerations for student development, curriculum guide objectives and pressures of accountability • (Duschl & Wright, 1989)
Background Literature • Epistemology of science is directly related to the nature of science • Epistemology of science can be considered as a tool for reflecting on contents of knowledge • (Larochelle & Desautels, 1991) • Implicit versus Explicit Nature of Science Instruction • The nature of science should be expressed explicitly for a positive cognitive outcome • (Bell, Lederman & Abd-El-Khalick, 1998)
Background Literature • Teachers’ understanding of the nature of science and classroom practice • Teachers’ conceptions of science do not necessarily influence classroom practice • (Lederman, 1999) • Bridging the gap between nature of science and scientific inquiry • Empirical research does not support the idea that scientific inquiry alone teaches concepts about the nature of science • (Schwartz, Lederman & Crawford, 2003)
Participants & Data Sources • Participants in research • Six teachers – 4th grade students • Data Sources • Interviews • Probing for beliefs, understanding and views on teaching practice related to inquiry-based learning in science • Concept maps • Probing for conceptual framework of inquiry-based science • Supplemental Data Sources • Research Memos • Reflections from Student Work Assessment • Surveys
Methods Qualitative Research Design: An Interactive Approach • (Maxwell, 1996) • Converted interview text into concept maps • Explored intersections of initial interviews and initial concept maps • Explored intersections of subsequent interviews and subsequent concept maps • Separated intersections into concepts and practice • Examined similarities and differences in initial intersections and subsequent intersections • Reviewed concepts maps on a structural level and on a textual level • (Spector, 2004) • Compared participant initial conceptions to subsequent conceptions and to an ideal model of inquiry
Validity Checks • Qualitative Research Design: An Interactive Approach • -(Maxwell, 1996)
Survey Results Common to Findings • Teachers felt asking students open-ended questions was important and reported that open-ended questions were prevalent in their classes • Teachers did not feel strongly that evidence should be supplied to support claims by students • Teachers reported a low importance for student designed activities to test ideas
Survey Results Contrasting Findings • Teachers reported a high level of explicit description of the habits of mind required for science in their class • Implies a gap between teacher perceptions and practice regarding the nature of science
Changes in Teacher Perceptions of Inquiry • Inquiry is no longer synonymous with the scientific method • “I think I thought before that it (inquiry) was . . . more like the scientific method and now I am seeing that it is not.” • “At the beginning . . . When I think about teaching science, it was the scientific method.” • Inquiry is not a linear process, but a cyclical one • “Inquiry is about so many different things.” • I thought before it (inquiry) was more linear.” • “ . . . not having students learn in steps.” • “Also that one question leads to another questions and it’s a cycle.”
Limited Concept of Inquiry • Teacher perception of inquiry as a general question-answer cycle is not exclusive to science as a discipline • “Inquiry is questioning . . . and their questions change” • “Students use their resources to find their answers” • “. . . curiosity and exploring questions” • Teachers’ conception of science inquiry incorporates few science process skills • Observing • Predicting • Experimenting • Communicating
Further Study • Videos of peer analysis of student work products could have revealed more about how teachers think about inquiry • Specific discussion of the features of the nature of science could clarify inquiry to the participants • Interviews could have questions probing teacher understanding of the nature of science and the connection to inquiry
Implications • An extension of this study could explore the effect of explicit instruction in the nature of science on teacher perceptions of inquiry • Could a deeper understanding of the nature of science help teachers become more proficient in teaching inquiry? • Difficult to distinguish between concepts and practice in teacher perceptions • Do teachers distinguish between their conception of inquiry and how inquiry is used as a practice?
