The Effectiveness of Teaching Through Video

An interesting short film on the effectiveness of teaching (science) education through video. This video, however, is not without criticism.

One thoughtful reader pointed out that “If you are going to question the effectiveness of Khan videos, run the test with Khan videos and see how subjects perform.” Khan videos are very different from some of the ones presented and that might impact visual memory and learning.

As an experiment, I've turned comments on for this post.

It seems if you just present the correct information, five things happen:

  1. You think you know it.
  2. You don't pay your utmost attention.
  3. You don't recognize that what was presented differs from what you were already thinking.
  4. You don't learn a thing.
  5. You get more confident in the ideas you were thinking before.

It turns out that presenting the information in a “confusing way” — a person representing the most common misconceptions — gained the best results.

Still curious? Neil deGrasse Tyson argues that persuading with facts is not enough.
