Rate the following essay on its writing, argument, and language skills:
In the article, "Making Mona Lisa Smile," the author Nick D'Alto presents information regarding Facial Action Coding System (FACS), a computer which that can sense people's emotions. D'Alto lists out many of the functions of FACS, and effectively uses these functions to show that this technology can be valuable in a classroom setting.

One direct mention of FACS' benefit in the classroom is mentioned in paragraph 6. The author writes, "a classroom computer could recognize when a stuedent is becoming confused or bored." This allows teachers to recognize these emotions more clearly, and switch the topic to somethng more interesting, in which the students will be more likely to pay attention. As a result, class focus will increase as well as students' grades. Thus, one can see that FACS can help increase the productivity in a classroom.

Another benefit of FACS is mentioned later in the text. D'Alto mentions how FACS can help people reproduce and replicate certain emotions: he had his actors carefully reproduce smiling and frowning as a way of creating these emotions on stage." Through studying the methods of FACS, people can learn to replicate emotions. This can prove to be helpful in classroom setting, because as mentioned in the text, "empathy may happen because we unconsciously imitate another person's facial expressions." When one students see his friend feeling down, he can help his friend cope by empathizing with him. Having FACS can allow students to practice and experience the relationship between facial muscles and emotions. As a result, this will foster positivity in the classroom.

Furthermore, through FACS, teachers can often tell whether a student is lying or not. The article mentioned how FACS can be used to tell if someone is falsely characterizing themself: "faces don't lie; these muscle clues are sometimes used to sport when a 'smiling' politician or celebrity isn't being truthful." These implications can also be demonstrated in the classroom, when a student is being untruthful about something. The teacher can use FACS to identify the emotions of the students, and make sure he gets a fair punishment.

Overall, FACS is a great tool with a wide variety of applications, including in the classroom. Although it is not a viable option in classrooms right now, it may become an important technology for society in the future.
