Redesigning Legacy Conceptual Inventories: Initial Results from the One-Dimensional Kinematics Subscale

This talk is part of a project (NSF award #2235518) to develop replacement instruments for the Force Concept Inventory (FCI) and the Force and Motion Conceptual Evaluation (FMCE). The project seeks to identify and develop subscales representing different dimensions of a Newtonian Force Concept. The talk will present a general overview of the project as well as preliminary pretest/post-test results. The first scale to be developed measures a knowledge of one-dimensional kinematics. More than 40 items were piloted and tested at 3 large research universities in the Spring 2024 semester producing over 2000 student responses. Both qualitative and quantitative validation was used to refine the instrument. Results of quantitative validation will be summarized. A 20-item instrument was given as a pretest and post-test at 3 institutions in Fall 2024. Preliminary analysis of pretest to post-test changes will be presented. This project ultimately will produce a short FCI/FMCE replacement scale with cross-norming data to the original instrument.
