Subclaims¶

q3 i? During the learning phase, groups with low information density perceived lower mental effort than groups with high information density. → Jimmy Zambrano 2019 q3 i? During the learning phase, low information density groups were more efficient than high information density groups. → Jimmy Zambrano 2019 (2)

Evidence¶

Jimmy Zambrano 2019¶

Jimmy Zambrano, Femke Kirschner, John Sweller, Paul A. Kirschner. (2019). Effects of group experience and information distribution on collaborative learning. Instructional Science. https://doi.org/10.1007/s11251-019-09495-0

q3 · i? · causal · r2

Learning-phase ANOVA of the 2×2 experiment, mental effort rated on a 9-point Paas scale averaged across group members: "groups with low information density (M = 6.80, SD = 1.80) perceived lower mental effort than groups with high information density (M = 7.89, SD = 1.68)".

"For mental effort, groups with low information density (M = 6.80, SD = 1.80) perceived lower mental effort than groups with high information density (M = 7.89, SD = 1.68)."

q3 · i? · causal · r2

Learning-phase efficiency contrast in the same ANOVA series: within this sentence "low information density (M = .29, SD = 1.09) was more effi- cient than high information density (M = − .30, SD = 1.11)"; no effect size is printed for this contrast here.

"For efficiency, experienced groups (M = .32, SD = 1.26) were more efficient than inexperienced groups (M = –.48, SD = .65) and low information density (M = .29, SD = 1.09) was more effi- cient than high information density (M = − .30, SD = 1.11)."

Discussion¶

Related Claims¶

• In the learning phase, group experience and information distribution each produce significant multivariate effects on performance, mental effort, and efficiency, without interacting — a broader claim this one bears on
• The efficiency advantage of prior collaborative experience emerges under high information density but not under low information density — related
• Low information density improves individual test performance in the short-term retention test, but the benefit fades by the delayed test — related
