text: in summary,The Facial Action Coding System can be valuable in a classroom setting by seeing if if a student is confused or bored and can modify the lesson accordingly. Another reason is it could have prevented alot of bad things from happening to schools. For example, the school stabbing in Pennsylvania by seeing that the kid was unhappy and angry and therefore, the staff could have stepped in and got him help before anyone was even hurt. The Facial Action Coding System is a very helpful tool.Extracurricular Activities are like music; some people like it, others do not. The principal at my school has decided that all students must participate in at least one extracurricular activity. I disagree, for the students may be shy, busy, or have money problems at home.
