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 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 is underway. This talk will discuss lessons learned in the validation process and present examples of both bad and good kinematics items. Results of quantitative validation will be summarized. This project ultimately will produce a short FCI/FMCE replacement scale with cross-norming data to the original instrument.
