q3 · i? · causal · r2

ANCOVA analysis (controlling for pretest) of 114 students in the Deep Thought tutor study found the Next-Step group significantly outperformed the Waypoint group on posttest Total Steps and Accuracy; "The WP group had 28 more total steps and had a 5% lower accuracy" on the posttest.

"More importantly, on the posttest, the NS group significantly outper- formed the Waypoint group on Total Steps ( F (2, 111) = 3 .73, p = 0.02) and Accuracy ( F (2, 111) = 2 .38, p = 0 .05)."
