Rate the following essay on its writing, argument, and language skills:
The FACS (Facial Action Coding System) is a valuable way to help students learn; it can tell when a student is bored and can modify the lesson to make it more interesting to the student. "A classroom computer could recognize when a student is becoming bored or confused".

FACS can have many different effects on an individual person. One example would be "...in a false smile, the mouth is stetched sideways using the zygomatic major and...the risorius....these muscles clues are sometimes used to spot when a "smiling" politician or celebrity isn't being truthful". Using the FACS people could tell whether or not someone is lying; this is especially helpful if the person lying is and important politician that could one day be leading a country.

FACS could also be used to help understand emotions better. "Empathy may happen because we unconsciously imitate another person's facial expressions". This could help people better understand one another. Say there are two beggars living on the street one of them is a real beggar with no money and the other is faking it just to get more money; FACS could be used to identify people who truly needs help by studying their facial muscles.

In conclusion FACS is valuable to students in a classroom because it can make the lesson the students are learning more interesting to them. It can also be used to tell whether a student is lying or not about cheating on a test or saying they accidentally left their homework at home when they really didn't do it at all. FACS can definitely improve the learning environment for students worldwide.
