Kahn Academy?

Interesting video about “watching” lectures.  http://fnoschese.wordpress.com/2011/03/17/khan-academy-and-the-effectiveness-of-science-videos/

Are students really learning or only hearing what they want to hear to justify what they already “know”.  I have the same problem with gravity that the video used as an example.

It is important that teachers in lower grade levels get the concepts right.  Students are much more receptive at the younger ages.  So, when we get them in high school, once they hear a topic they already know, they had better know it correctly, or they will more than likely not be corrected.

I like that the term “confused” was used as a sign of corrected misconceptions.
