text: In the passage, the article states that a classroom computer could recognize a stuudent becoming confused or bored (Dr. Huang). After that, it could modify the lesson similar to what an effective human instructor could do. My response is that a classroom computer that has FACS(Facial Action Coding System) can help the students lessons and making them understand easier. For example, if the FACS detects the student being confused while doing work on his laptop, the laptop can try to make the lesson more understanding in a level the student is in.
