text: The first way, new facal technology could help in the classroom is by showing when a student is confused and not sure whats going on.

As for example, of this when doing math homework online or english the computor could recoginize when the student is confused and then send the student step-by-step insturction. Also the teacher could request this imfomation on which problem the students are confused on and go over them into more detailed.
