q2 i? On momentum post-test questions, no statistical difference in student performance was found (p = 0.65) among the five cooperative-group styles with verbal TA interaction, suggesting the tutorial material rather than instructor quality most impacts understanding of unfamiliar content. → Slezak 2011

q2 · i1 · causal · r2

Null comparison across Styles 2-5 and the prior ideal implementation on momentum questions. The mean score of all students in Figure 3 was 34%, with pre-test means near 0-4%, indicating the tutorial was students' first exposure to the theorem.

"Although the ideal implementation of the prior study appears to stand out in Figure 3 in terms of student performance on the post-test for the momentum ques- tions, no statistical difference in student performance is found ( p = 0 .65) amongst all five displayed styles."
