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 i1 In the short-term retention test, experienced groups were more efficient than inexperienced groups for high information density tasks (η²p = .03) but not for low information density tasks. → Jimmy Zambrano 2019
q3 i2 The same interaction pattern held in the delayed retention test for instructional efficiency, with a small-to-medium effect at high information density (η²p = .04). → 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 · i1 · causal · r2
ANOVA interaction in the short-term retention phase. The interaction showed an efficiency advantage for experienced groups only where task information density was high (η²p = .03); at low density the groups "are not significantly different", so the advantage is conditional rather than general.
"Regarding instructional efficiency, the significant interaction between main effects indicated that for the task with high information density, experienced groups are more efficient than inexperienced groups, (p = .02, /u1D7022 p = .03). However, for the task with low information density, experienced groups and inexperienced groups are not significantly different (p = .37, /u1D7022 p = .01)."

q3 · i2 · causal · r2
Delayed retention phase efficiency interaction: experienced groups were more efficient only for high information density tasks (η²p = .04, a small-to-medium effect); at low information density the difference was not significant (η²p = .00).
"The significant interaction between main effects indicated that for the task with high information density, experienced groups are more efficient than inexperienced groups, (p = .01, /u1D7022 p = .04). However, for low information density, experienced and inexperienced groups are not significantly different (p = .90, /u1D7022 p = .00)."

Related Claims¶
- Experienced groups show higher instructional efficiency than inexperienced groups in the delayed retention test after collaborative learning — related
- The collective working memory effect: group learning is more efficient than individual learning for high-complexity tasks, but individual learning is more efficient for low-complexity tasks — related
- Segmentation Benefits Shrink With Expertise — related
- Groups with prior collaborative experience on similar tasks outperform inexperienced groups on individual retention tests after collaborative learning of complex tasks — related
- In the learning phase, group experience and information distribution each produce significant multivariate effects on performance, mental effort, and efficiency, without interacting — reports the opposite
- Low information density improves individual test performance in the short-term retention test, but the benefit fades by the delayed test — related
- Low information density reduces mental effort and increases efficiency during the collaborative learning phase — related
- Collaboration facilitates learning only under specific knowledge and experience conditions; with advanced learners it can be detrimental via the expertise reversal effect — a broader claim this one bears on
- Collaborative tasks should be complex enough that joint effort is worthwhile, engaging the collective working memory effect — related
