Rate the following essay on its writing, argument, and language skills:
In a classroom full of students, teachers don't usually have the time to check that every student is enjoying the lesson, paying attention while being productive in class. Many students might be tired from a long night of homework, and what would the teacher do if a student was mentally tired? The teacher could get the student to do some form of physical activity like jumping jacks, but this will not get a student mentally active and engaged in class.

In the article, "Making Mona Lisa Smile", the author describes a computer program that can read people's emotions by the muscles in their face. The author never states that the program can scan multiple faces at once, and if it could, how would it make a whole class of moody students all happy at the same time. A student could be bored from the lesson and another be stressed out by a test the next period. How would the program help the teacher change all the different emotions that the students have to happiness.

This program can read faces and guess what emotion that person is feeling at that exact moment. This sounds very useful

and it is, for one person, but not a whole classroom of people. Until the program can create solutions to help all the students to fell better, it would just stress out the teacher by trying to make everyone happy, which if we look at history, is almost impossible.
