The review reports a true experimental 2 × 2 factorial RCT (n = 160 seventh-graders, High quality) in which "instructional videos produced large main effects on science learning (η2 = 0.27)" and the AI chatbot produced significant interaction effects on extraneous cognitive load.

"Huang and Chen (2025) found in a 2 × 2 factorial experiment (n = 160) that instructional videos produced large main effects on science learning (η2 = 0.27), while the AI chatbot produced significant interaction effects on extraneous cognitive load, suggesting complementary rather than redundant functions."
