text: I think that this type of technology is actually very useful, my reasons for that come from the article when the author tells about how using a special camera can detect when someone is becoming bored when doing homeowrk or doing someother type of school work on the computer. If you can tell when comeone is confused or bored then you could really get some help or get a better, more fun filled math questions. Than would make students more productive and want to actually learn rather then when you are bored and doing ISTEP, they can make the test more exciting.
