Khan Academy and the Effectiveness of Science Videos
That was fascinating, and seems really relevant to self-learning. I'm sure I do this all the time ("this" meaning "Believing that I'm learning when I'm really just strengthening my confidence in my misconceptions").
Any thoughts on how to avoid/combat this? I'm open to anything from mantras to tests to chemicals.
That is fascinating. It really says something interesting about the learning process.
I am curious how far the results generalize. Is this still a serious problem with more knowledgeable students? Is it a problem with math education?
This is worth going to for the text attached. It sets out an interesting phenomenon in teaching people with video.
The phenomenon doesn't just apply to videos.
I just read the text, and I didn't see why I should be less optimistic about Khan. What are these studies/tests that show students aren't really learning the science? Remember, Khan does its own tests to check that you learn the material. The relevant question is, are students learning more or less than they would through standard classroom instruction, and is this an artifact of Khan's lesser skill in science teaching specifically, or the entire enterprise of teaching science through a video? Consider that it seems to accept Khan can teach the other subjects just fine...
