Rate the following essay on its writing, argument, and language skills:
There has been a breakthrough in the science of emotion. The Facial Action Coding System or FACS, developed by Prof. Thomas Huang, is a new technology that can read and judge your emotions. Though this technology is outstanding, it is not practical for use in schools.

The machine is more than likely to expensive to have for each kid in a school. If the machine only cost $100 it would still take $200,000 to buy one machine for a high school that only has 2,000 students.

Another reason the machine is impractical is because of the fact that it is just simply not needed. Schools opperate perfectly fine without the machines today. Humans have learned to read emotions very well. One can tell when their friend is upset just by reading their body language. Schools do not need expensive machines to do what humans can already do. Instead of spending so much money on machines that do something humans already know how to do, schools could sped their money on other things that are needed like textbooks, paper, and other school supplies.

One could argue that the machines are very cool and should be put in schools to help teachers better understand how students are fealing, it is not needed in schools. It would not help get any kearning done in the classroom or make it easier for students to get through the lesson. Although Prof. Huang says that the machine could detect when a student was getting bored and changfe the lesson to get students more involed, it would mean that the lesson would not be the same for each student and they could learn something a little different from the rest of the class which could damage homework or test grades.

Though the FACS is very cool it is totally impractical. It is a machine that just replaces another thing that humans can alredy do. It is not woth the money for something that does what humans do for free. It would not help students learn anything any better than they already do either. As demonstrated through all of the reasons above, the FACS machine is not needed in schools.
