q3 i? A significant three-way interaction showed that the positive effect of a visible instructor's gestures and gaze shifts on knowledge acquisition improved as perceived difficulty increased. → Reuter 2025

Evidence¶

Reuter, T., Lazzara, L., & Leuchter, M. (2025). Static, dynamic, or human? The role of slide dynamics and instructor cues in video lectures. Education Tech Research Dev. https://doi.org/10.1007/s11423-025-10572-0

q3 · i? · causal · r2

In the multilevel regression for research designs, "a significant three-way interaction was observed for the topic of research designs (postcontrast2difficulty), B = 0.29, SE = 0.13, p =.027", indicating instructor signaling helped more as perceived difficulty increased.

"Additionally, a significant three-way interaction was observed for the topic of research designs (postcontrast2difficulty), B = 0.29, SE = 0.13, p =.027, suggesting that the positive effect of a visible instructor’s gestures and gaze shifts on knowledge acquisition improved as perceived difficulty increased."
