A Case Study Into Middle School Students' Conceptualizations Of Motion And Interpretations Of Negative Velocities, Peter A. Colesworthy

Electronic Theses and Dissertations

Student difficulties surrounding motion have been well documented for many years. This work was inspired by the work of former MST students into the instruction of Newton‟s Second Law of Motion at the middle school level. The purpose of this study was to further investigate how middle school students talk and reason about motion. Particular attention was paid to how students defined the term “motion,” how those definitions fit into a larger framework of what encompasses understanding motion at the middle school level, and how students justified negativity of a calculation of a negative velocity.

Investigating Teachers' Content Knowledge And Pedogogical Content Knowledge In A Middle School Physical Science Curriculum On Force And Motion, Daniel Patrick Laverty

Electronic Theses and Dissertations

Teaching is a profession that requires the incorporation of many types of knowledge in order to create effective instructional experiences that promote student learning. Teachers need to blend their knowledge of the content with the methods for delivering that content and an understanding of their students' thinking. With increasing concern in the United States over student achievement in science and mathematics, there is ongoing discussion about which elements of teacher knowledge most directly correlate with effective instruction. How do specific strands of teacher knowledge blend to influence student learning outcomes? This study explores the roles of teacher content knowledge (CK) …
