The Relationship Between Nature Of Science Understandings And Science Self-Efficacy Beliefs Of Sixth Grade Students, Elisabeth A. Parker

Middle-Secondary Education and Instructional Technology Dissertations

Bandura (1986) posited that self-efficacy beliefs help determine what individuals do with the knowledge and skills they have and are critical determinants of how well skill and knowledge are acquired. Research has correlated self-efficacy beliefs with academic success and subject interest (Pajares, Britner, & Valiante, 2000). Similar studies report a decreasing interest by students in school science beginning in middle school claiming that they don’t enjoy science because the classes are boring and irrelevant to their lives (Basu & Barton, 2007). The hypothesis put forth by researchers is that students need to observe models of how science is done, the …

Preservice Teachers' Use Of Lesson Study In Teaching Nature Of Science, Amy Mcdowell

Middle-Secondary Education and Instructional Technology Dissertations

The purpose of this study was to explore preservice teachers’ lived experiences in a lesson study focused on teaching and learning nature of science (NOS). The body of knowledge about shifting pre- and in-service novice NOS understandings is substantial. The focus of science education research is now exploring ways to move these informed NOS understandings into classroom practice (Abd-El-Khalick & Lederman, 2000b).

The research questions guiding the study were (a) how do preservice teachers’ understandings of NOS shift as a result of the lesson study experience?, and (b) how does the reflective practice that occurs in lesson study influence preservice …

Considering Hans-Georg Gadamer's Philosophical Hermeneutics As A Referent For Student Understanding Of Nature-Of-Science Concepts, Jared Michael Rashford

Middle-Secondary Education and Instructional Technology Dissertations

The purpose of this study is to examine philosophical hermeneutics as a referent for student understanding of Nature-of-Science (NOS) concepts. Rather than focus on a prescriptive set of canons used in addressing NOS pedagogy in K-12 schools, this study seeks to explicate a descriptive set of principles based on Hans Georg-Gadamer’s theory of interpretation that has the potential for developing dispositions necessary for understanding. Central among these are the concepts of fore-structure, prejudice, temporal distance, and history of effect, all of which constitute part of the whole of the hermeneutic circle as envisaged by Gadamer. As such, Gadamer’s hermeneutics is …

Conceptual Change In Pre-Service Science Teachers' Views On Nature Of Science When Learning A Unit On The Physics Of Waves, Ehsan Habib Kattoula

Middle-Secondary Education and Instructional Technology Dissertations

Recent reform efforts in science education have culminated in National Science Education Standards (NSES), which include the nature of science and science inquiry themes across all grade levels. Consideration must be given to pre-service science teachers’ nature of science conceptions and their perceived roles in implementing the nature of science in the science classroom. This qualitative study investigates how pre-service science teachers’ views about the nature of science develop and change when learning a college physics unit on waves in an urban university. The study uses case study methodology with four pre-service science teachers as individual units of analysis. Data …
