text: I think its a great idea to use for school, so teachers can tell how the student is feeling and can find a way to help them. In paragraph 6 the author uses the exmple of how we could use this new technology during school for example he wrote, "If you smile when a web ad appears on you screen a similar ad might follow. But if you frown, th next ad might be different." And instead of ads they could be explanations on how to do a problem. I think that that would inprove the students learning.
