Subclaims¶

q2 i? Mediation analysis showed the Tool-use effect on HPQ is mediated by the amount of fewer performed macro-actions, but not by micro-actions; the direct effect remained significant. → 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

q2 · i? · causal · r2

Regression-based mediation (PROCESS) with Tool-use as independent variable and log-file activity as mediators; the direct effect on HPQ remained significant (path c', p < 0.001), indicating partial mediation. No standardized effect size was printed for the indirect effect.

"We found that the relationship between Tool-use and HPQ is mediated by the amount of less performed macro-actions, ab = − 0.119, 95% CI[− 0.294, − 0.011], but not by the amount of performed micro-actions, ab = − 0.091, 95% CI[− 0.389, 0.227]."
