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.
