text: When some people are working on assignments on they often use trial and error and sometimes they just need to think about the problem before they do it. This could get confusing for the computer because when your thinking you often will look confused or you might be confused but later figure it out. You shouldnt have to rely on a computer to tell how your feeling to get help. Dr. Huang said "A classroom computer could recognize when a student is becoming confused or bored... Then it could modify the lesson, Like an effective human instructor." This ay sound like a good idea but if a student is getting bored they dont need there lesson modified to help them and most kids are going to be bored during school thats just how the majority of students are.
