q3 i2 With the control group included, the control condition outperformed both tool conditions on understanding of interrelations, and outperformed the annotation condition (not the hyperlink condition) on transfer knowledge. → 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 · i2 · causal · r2

MANOVA including the control group on the three conceptual-understanding measures; Tukey post-hocs showed control > annotation on interrelations (p = 0.022) and transfer (p = 0.010) and control > hyperlinks on interrelations (p = 0.003).

"Post-hoc univariate ANOVAs revealed significance for the variables 'understanding of interrelations', F(2,137) = 6.530, p = 0.002, partial η2 = 0.087, and 'transfer knowledge', F(2,137) = 4.294, p = 0.016, partial η2 = 0.059, both indicating that the control group outperformed the two other conditions"
