Subclaims¶

q2 i? On kinetic energy post-test questions, the ideal implementation performed significantly better (p < 0.05) than all other styles except Style 4 (limited Socratic dialogue, p = 0.14), and Style 2 (complete written answers) was statistically lower than Style 4 and the prior study's ideal implementation. → Slezak 2011

q2 · i? · causal · r2

Post-hoc LSD comparisons among the cooperative-group styles (Styles 2-5 plus the prior study's ideal implementation; N=45, 38, 41, 47, 63): Style 2 gave detailed written answer keys and did not allow verbal TA interaction on tutorial content, while Styles 3-5 had TAs interact verbally. The article prints p-values but no effect size. Figure 3 shows progressive improvement as instruction moves closer to the ideal implementation model.

"the ideal implementation style performed sig- nificantly better ( p < 0.05) than all other styles with the exception of Style 4 ( p = 0 .14)."

• In an immediate post-test design, participants with an unrestricted chatbot achieved significantly higher learning deltas than participants with a Socratic chatbot (d = 0.80) or an EEG-adaptive exercise system (d = 0.85) — the general claim this finding bears on, with the studies behind it
• A computer-based implementation of the tutorial yields the lowest post-test scores, statistically lower on momentum than every other style in the same study and the prior study's ideal implementation — related
