q3 i? In both groups students attempted to construct steps for almost 80% of the tasks they worked on, and the numbers of tasks worked on and attempted did not differ significantly between groups. → Tacoma 2020

In the randomized experiment, Table 3 reports tasks worked on (experimental M=4.8, SD=1.5; control M=4.9, SD=1.5, p=.391) and tasks with step construction attempted (M=3.8 vs 3.9, p=.537). No effect size was printed, so impact is null; equivalence was not tested.

"The numbers of tasks students worked on and attempted step construction for did not differ significantly between groups"

Discussion¶

Related Claims¶

• Students receiving intelligent ITS feedback spent significantly more time and made significantly more steps on the hypothesis-testing tasks than controls — reports the opposite
• Error rates per completed problem-solving step did not significantly differ between conditions — related
