Subclaims

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.

q3 i3 In the learning phase, experienced groups outperformed inexperienced groups on task performance. → Jimmy Zambrano 2019 q3 i2 In the delayed retention test one week later, experienced groups still outperformed inexperienced groups on individual test performance. → Jimmy Zambrano 2019 (2)

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 · i3 · large effect, ηp² = .26 · causal · r2

ANOVA from the learning phase of the 2×2 experiment. Of 240 secondary school students recruited, the learning phase analysed 65 three-person groups after exclusions (39 experienced, 26 inexperienced), at group level (F(1, 61) = 21.12, p < .001, ηp² = .26, Table 4). On break-even problems, "experienced groups (M = .52, SD = .42) outperformed inexperienced groups (M = .13, SD = .21)".

"Concerning performance, ANOVA revealed that experienced groups (M = .52, SD = .42) outperformed inexperienced groups (M = .13, SD = .21)."

q3 · i2 · medium effect, ηp² = .09 · causal · r2

Analysis of the delayed retention test taken seven days after the learning phase, solved individually: three problems similar to the learning tasks, with the business situation and cost names varied. "experienced groups (M = .46, SD = .30) outperformed inexperienced groups (M = .29, SD = .26)" (F(1, 177) = 17.23, p < .001, ηp² = .09, Table 4).

"For performance (Table 4), the analysis revealed that experienced groups (M = .46, SD = .30) outperformed inexperienced groups (M = .29, SD = .26)."
