Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i3 Substantive comments per discussion group were significantly higher in the self-study condition (d = 1.21). → Jaeseo Lim and Jooyong Park 2026 q2 i3 Co-constructive turns per interaction episode were significantly higher in the self-study condition (d = 1.59). → Jaeseo Lim and Jooyong Park 2026 (2)

q2 · i3 · causal · r2

Dialogue analysis of audio- and video-recorded group discussions, coded by three independent raters (ICC 0.97 for episodes). The proportion of substantive comments was also "significantly higher in the self-study condition (94.15%) than in the lecture condition (72.56%), χ²(1) = 228.64, p < .001."

"the number of substantive comments per discussion group was significantly higher in the self-study condition (M = 48.36, SD = 23.22) than in the lecture condition (M = 23.50, SD = 11.04), t(19) = 3.08, p = .006, d = 1.21."

Coded transcripts also showed more substantive comments per interaction episode in the self-study condition, M = 12.78 vs M = 6.44, t(19) = 2.93, p = .009, d = 1.28.

"Per interaction episode, students in the self-study condition had a significantly higher number of co-constructive turns ( M = 6.16, SD = 3.07) than students in the lecture condition (M = 2.46, SD = 0.85), t(19) = 3.65, p = .002, d = 1.59."
