Subclaims¶

q3 i? The combined experimental groups outperformed the control group on knowledge gains for all three topics, indicating overall effectiveness of the video lectures. → Reuter 2025

Evidence¶

Reuter 2025¶

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

Comparing the combined experimental groups with the control group, "Significant interactions between change over time (pre-posttest) and group" were found for all three topics, "indicating an overall effectiveness of the video lectures."

"Significant interactions between change over time (pre-posttest) and group in participants’ knowledge of samples, B = 3.03, SE = 0.25, t(312) = 11.90, p <.001, research designs, B = 2.84, SE = 0.27, t(312) = 10.44, p <.001, and measurement, B = 4.50, SE = 0.23, t(312) = 19.44, p <.001, were found, indicating an overall effectiveness of the video lectures."

• Students who teach a ChatGPT teachable agent in natural language achieve greater knowledge gains than students who learn the same material from online videos — related
• Instructional lecture produced no immediate significant change in metacognitive knowledge or regulation of cognition — related
• About two-thirds of Freeman et al. (2014) articles reported results favoring only the active learning group, but most comparisons were active learning versus lecture with weak internal validity controls — a broader claim this one bears on
• Participants acquired knowledge to a similar degree from AI-generated and human-made teaching videos as measured by multiple-choice exam results — a broader claim this one bears on
