Subclaims¶

q3 i? Experimental (N=158) and control (N=147) groups performed similarly on 31 follow-up sub-tasks, with mean ratios of correct first-attempt answers of 0.72 (SD=0.07) and 0.71 (SD=0.08) respectively. → Tacoma 2020

q3 · i? · causal · r2

Comparison of follow-up task performance between groups in the randomized experiment, on 31 follow-up sub-tasks without intelligent feedback. No significant difference was reported and no effect size was printed, so impact is null; equivalence was not tested.

"the mean ratio of correct answers was 0.72 (SD = 0.07) in the experimental group and 0.71 (SD =0 . 0 8 ) in the control group"

Related Claims¶

• Students receiving intelligent ITS feedback spent significantly more time and made significantly more steps on the hypothesis-testing tasks than controls — related
• ITS feedback availability interacted with task number so that experimental-group students increasingly outperformed controls in solving tasks over time — related
• Students receiving intelligent ITS feedback made significantly fewer errors in hypothesis-testing logic than students receiving verification feedback only — related
