q3 i? For high-proficiency students, the WP group took longer and made more mistakes during training, but there were no significant posttest differences between NS-High and WP-High groups. → Christa Cody 2021

Christa Cody, Mehak Maniktala, Nicholas Lytle, Min Chi, Tiffany Barnes. (2021). The Impact of Looking Further Ahead: A Comparison of Two Data-driven Unsolicited Hint Types on Performance in an Intelligent Data-driven Logic Tutor. https://arxiv.org/abs/2102.05741

q3 · i? · causal · r2

Median-split analysis of high-proficiency students (NS-High n = 27, WP-High n = 30) found significant training differences favoring Next-Step hints, including a significantly lower hint justification rate for the WP group. "For the posttest, there were no significant differences between the NS-High and WP-High groups, although the WP-High group performed worse on average."

"For the training, the WP group took longer and made more mistakes, as indicated by the Total Time ( F (2, 54) = 17 .22, p < 0.01), Accuracy (F (2, 54) = 5.291, p < 0.01), and attempted more steps ( F (2, 54) = 3.917, p = 0.03)."
