Subclaims¶

q1 i? At t1 the odds of incorporating the partner's evidence into answers on the pirate-status question were 10.80 times higher for DDR dyads, χ²(1, N = 28) = 7.34, p = .007; the conviction question showed no relevant differences. → Heimbuch 2018 q1 i3 In the pre-study, the DDR group's overall knowledge-test score was moderately higher than the BRD group's (r = .44). → Heimbuch 2018 (2)

q1 · i? · causal · r1

Small laboratory pre-study (N = 28 at t1, N = 22 at t2): DDR vs BRD dyads categorised on whether open-ended answers integrated only own material (A or B) or the partner's evidence (A and B). The t1 χ²(1, N = 28) = 7.34, p = .007 supports the main-topic contrast; no standardized effect size is printed.

"The odds of incorporating evidence from the partner’s learning material into one’s own answer was 10.80 times higher at t1 and 4.08 times higher at t2 if students collaborated with the DDR script (cf. Figure 5)."

q1 · i3 · causal · r1

Pre-study Mann-Whitney comparison of the overall knowledge-test scores (Table 3): BRD M = 23.67 vs DDR M = 25.54, U = 32.50, p = .043, r = .44 [-.06, .72], with the article noting low statistical precision due to the small sample.

"Overall, participants in the BRD group scored two points lower compared to the DDR group (cf. Table 3)."
