I watched the U-tube of Professor Khan's discussion about atomic structure and enjoyed it very much. I liked the use of the smart blackboard and images and videos . I found his conversational style to be very engaging, and his explanations excellent. However I do not think that this style of presentation is very different in content and style from what many of us use in the classroom, though not all of us have the technology that he used available. I think that using some of his presentations in class from time to time would be a great addition to any class. But in my experience students do not react well to a course taught completely on-line or by using videos, power points, u-tube etc all the time. They like the "real" interaction with a professor. They like to be able to ask questions. They really like their teacher to solve example problems. So these kinds of presentations make a great addition to a class, but should not, in my opinion, be the way the whole class is taught.
