q2 i? Real FCI data from three calculus-based mechanics classes show a fairly linear change-score relation with pretest score above 0.5, with one class showing curving down at low pretest scores. → Lei Bao 2007

q2 · i? · the article prints no effect size for this finding · theoretical · r3

Numerical analysis (Section V) of real FCI data from three classes (interactive labs N1~350; traditional N2~1500; honors N~200), plotted as binned averages with standard errors less than 0.02. The data show a 'fairly linear relation' above pretest 0.5 and curving down at low scores for one class.

"In general, the change score shows a fairly linear relation with the pretest score especially for the part where pretest score is greater than 0.5. This is consistent with the theoretical curves shown in Figure 3, in which the logistic model (γ-process) shows more non-linear trend with pretest score below 0.5."
