Abstract
The complete report from Richard Hake's long-term study of interactive engagement (IE) techniques and their effect on the understanding of physics by non-physics majors. The study analyzed diverse student populations in high schools, colleges, and universities and used pre- and post-instruction testing to determine the gains in each group. IE techniques were shown to improve student's understanding at a significantly higher rate than traditional instruction. Additionally, these IE techniques are applicable to teaching a wide range of topics. Educational levels: Graduate or professional
