text: Students should have to participate in at least one extracurricular activity because it will give them an opportunity to try new things, make new friends, and it will be better for them in the future. If schools had this rule, then more students would enjoy going to school, and they would become more involved in the school. Once people are out of their comfort zone, then they will discover new interests that they never knew they had. Overall, this rule would help many students come out of their comfort zones and become more confident people. According to the article "Making Mona Lisa Smile," there is a new technology called the Facial Action Coding System (FACS) that enables computers to identify human emotions. This technology is relatively brand new. It creates a 3-D computer model of all fourty-four major muscles in the face that move like human muscles as well. Then, psychologists have classified six basic emotions that are associated with different movements in the facial mucles. This new technology could result in many benefits in our community as well as all around the world. The use of the Facial Action Coding System to read the emotional expressions of students in a classroom is valuable because it would allow teachers to know when students become confused, are being dishonest, or are depressed and possibly having problems at home.
