Hake showed that, for more than 2000 introductory physics students in traditional lecture courses, the average normalized gain on the FCI was 23% 4%. Whereas, for more than 3000 introductory physics students in IE courses, the normalized gain on the FCI was 48% 14% 6 , which is quantitative evidence that the student centered, interactive engagement teaching method promotes a greater conceptual understanding of Newton’s laws of motion than the traditional, passive student lecturing method
