"College students spend a lot of time listening to lectures. But research shows there are better ways to learn. And experts say students need to learn better because the 21st century economy demands more well-educated workers."
Dr. Eric Mazur, the Harvard professor heard in the podcast, also gave a presentation on student learning at Penn State last year. The media player opens in a browser window, and to view the lecture instead of the PSU-Hershey placeholder, you (weirdly) have to click what looks like a "refresh" icon on the right-hand side of the screen. Dr. Mazur is given a lengthy introduction, but starts his talk at 3:45.
