Effects of Observing the Instructor Draw Diagrams on Learning from Multimedia Lessons

Résumé du livre

This research tested whether viewing an instructor draw diagrams improves learning from multimedia lessons compared to viewing equivalent static (e.g., already-drawn) diagrams. In a series of five experiments, participants viewed a short video-based lesson about how the Doppler effect works. Some students viewed already-drawn diagrams while listening to a concurrent oral explanation (control group), whereas other students listened to the same explanation while viewing the instructor actually draw the diagrams by hand (draw group). All students then completed retention and transfer tests on the material. Results of Experiment 1 indicated that watching the instructor draw diagrams (by viewing the instructor's full body) resulted in significantly better transfer test performance than viewing already-drawn diagrams for learners with low prior knowledge (d = 0.58), but not for learners with high prior knowledge (d = -0.24).
