PE-CAP: Redesigning Legacy Conceptual Inventories: Qualitative Validity Evidence from Student Reasoning in Cognitive Interviews
ORAL
Abstract
A project (NSF award #2235518) is underway to use evidence-centered design to create a replacement for the Force Concept Inventory (FCI) and Force and Motion Conceptual Evaluation (FMCE) comprising flexible subscales developed with input from the physics education community.
We have used the three-step test interview process to collect extensive data on students’ reasoning processes as they work problems from subscales on one-dimensional kinematics and dynamics. In this talk, we’ll share how this rich data has been used in item development and revision and provide detailed validity evidence for sample items.
