q2 · i? · causal · r2

Topic-by-quarter fixed-effects ramp regression on 3,197,803 ALEKS learning interactions (2015 Q3–2025 Q3), comparing AI-susceptible word problems to AI-resistant graph problems. The college estimate is "β=− 0.0284,p< 0.001", a 26.9% cumulative reduction; graph-problem learning times remained stable.

"learning time for word problems declines by 2.80% per quarter relative to graph problems (β=− 0.0284,p< 0.001; per-quarter percent computed as (exp(β)− 1)× 100), accumulating to a 26.9% cumulative reduction over eleven post-ChatGPT quarters"
