text: I think the use of the Facial Action Coding System is a well needed thing for schools because it could tell your teacher whats going on whether you need help or not or if your going through something and need to talk to someone. The Facial Action Coding System would be a great thing to have in school because some kids are shy an dont like to talk and raise there hands in class infront of everyone and if you dont ask questions when you dont understand something that could cause you to fail the class all because of your shyness.
