Abstract Title: Differences in the Predictive Power of Pretest Scores of Students Underrepresented in Physics
Abstract: This study reports student performance on physics conceptual inventories: the FMCE (N=1628) and the CSEM (N=1277). Pretest, post-test, and in-semester test averages are reported for students of different gender, race/ethnicity, first generation status, and rural/urban status; significant differences were identified between demographic groups. For the CSEM, Henderson et al. reported that the pretest scores of women were much more weakly correlated to a latent variable measuring conceptual knowledge than the pretest scores of men. The current study reports the correlation of FMCE and CSEM pretest scores with post-test scores and in-semester test averages. While many of the correlations were similar, for some of the demographic groups, the correlations were substantially different.  As such, pretest scores may not accurately predict performance for some demographic groups. Multiple linear regression was used to explore the effects of gender, race/ethnicity, first-generation status, and rural-urban status.
