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 The learning-phase MANOVA showed a large multivariate main effect of group experience and a medium-sized main effect of information distribution, with a nonsignificant interaction. → Jimmy Zambrano 2019
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 · i3 · causal · r2
Omnibus MANOVA over learning-phase performance, mental effort, and efficiency: group experience η²p = .26 (large) and information distribution η²p = .10; the interaction was nonsignificant (F(2, 60) = .67, p = .52).
"MANOVA revealed significant main effects for group experience, F (2, 60) = 10.40, Wilks' Λ = .74, p < .001, /u1D7022 p = .26, and information distribution, F (2, 60) = 3.33, Wilks' Λ = .90, p = .04, /u1D7022 p = .10, which indicate that these variables affect a combination of performance, mental effort, and efficiency scores."
Discussion¶
Related Claims¶
- Experienced groups show higher instructional efficiency than inexperienced groups in the delayed retention test after collaborative learning — related
- The efficiency advantage of prior collaborative experience emerges under high information density but not under low information density — reports the opposite
- Low information density reduces mental effort and increases efficiency during the collaborative learning phase — a narrower finding that bears on this claim
- Visualization format has a large multivariate and univariate effect on identifying motions and spatial arrangements — related
- Groups with prior collaborative experience on similar tasks outperform inexperienced groups on individual retention tests after collaborative learning of complex tasks — related
- Low information density improves individual test performance in the short-term retention test, but the benefit fades by the delayed test — related
