Online course data show that video lectures are not the best way to learn. Koedinger didn’t study live lectures, but recorded ones that were part of a free online psychology class produced by the Georgia Institute of Technology. He and a team of four Carnegie Mellon researchers mined the data from almost 28,000 students who took the course over the Coursera platform for Massive Open Online Courses (MOOCs). They found that video lecturers were the least effective way to learn. Students who primarily learned through watching video lectures did the worst both on the 11 quizzes during the 12-week course and on the final exam. Students who primarily learned through reading, or a combination of reading and video lectures, did a bit better, but not much. The students who did the best were those who clicked on interactive exercises.
