Subclaims¶

q3 i1 Dyads slightly outperformed individuals on hypervideo product quality, but the setting effect was only marginally significant (d = 0.36). → Ruf 2023

Evidence¶

Ruf 2023¶

Ruf, A., Zahn, C., Roos, A.-L., & Opwis, K. (2023). How do enhanced videos support generative learning and conceptual understanding in individuals and groups? Education Tech Research Dev. https://doi.org/10.1007/s11423-023-10275-4

q3 · i1 · causal · r2

Two-way ANOVA on HPQ in the lab experiment; "dyads (M = 4.82, SD = 0.6) slightly outperformed individuals (M = 4.63, SD = 0.5)" with p = 0.061. Information structuring showed a similar marginal setting effect (p = 0.065, d = 0.32).

"a marginal significant effect for Setting was found, F(1,88) = 3.605, p = 0.061, partial η 2 = 0.039, d = 0.36, indicating that dyads (M = 4.82, SD = 0.6) slightly outperformed individuals (M = 4.63, SD = 0.5), as expected in H2c."
