Rate the following essay on its writing, argument, and language skills:
Facial expressions. Sometimes they speak louder than words. Have you ever been in class and you just dont get what the teacher is teaching but you dont really wamt to speak up? Well science has you covered with one bright new invention... face scanners.

I know what you are thinking. How is a face scanner going to help me in pre calculus? Heres how. The face scanner is a new peice of technology that reads your emotional expressions. Picture this. you are on your computer doing math and you arent understanding. What if your computer broke the equations and problems down to make it more simple because it read that you were confused. Dr. Huang, a college preofessor, predicts that " A classroom computercould recognuze when a student is confused or bored. Then it could modify the lesson like an effective human instructor. This would be very valuable. Some students get stumped by certain things in the classroom and they dont ask the teacher for help in fear of being laughed at or made fun of because they dont know. This would help the student to where he doesnt even need to ask to go deeper into something because the computer can tell by his face that he doesnt get it. The computer can also read when the person is bored. I think this is a big one as well. Most students wont go out ad tell the teacher that the lesson is boring but they sure do think it. wouldnt it be great that a computer reads that and sees the student is bored and makes the lesson more entertaining? I think that is a great idea and would get the students more active and participating more because the topic would be more fun.

In conclusion face scanners are going to be a big thing. I think they could greatly improve the school systems and help the students with their work. Like i said not everyone tells you what they are thinking and sometimes you can read it on their face. Why not let computers help us with that?
