Abstract Title: Aspects of Factor Analysis Applied to the Force Concept Inventory
Abstract: The application of factor analysis to the Force Concept Inventory (FCI) has proven to be problematic.  Some studies have suggested that factor analysis of test results serves as a helpful tool in assessing the recognition of Newtonian concepts by students.  Other work has produced at best ambiguous results.  We report on our analysis of over 400 pairs of pre- and post-tests. The factor structure is more pronounced in the post-test with a more readily identifiable association between factors and physical concepts. We discuss whether such an evolution to a more robust factor pattern constitutes evidence of instructional efficacy.
