text: This is a very vaulble system if a kid is afriad maybe somethig is going on at home to make them feel this way the teachers would be able to detect it and get the student the help it needs . In the article it says " A classroom computer could recognize when a student is becoming confused or bored " this means if the student is confused the teacher would know to maybe take the lesson a little slower and help the kid out or if multiple students look confused she could maybe just go over the lesson all over again.
