text: In conclusion, as the text states "According to the Facial Feedback Theory of Emotion, moving your facial muscles not only expresses emotions, but also may even help produce them (par 9)." This evidence above is the exact reason why FACS would be a outstanding investment for classrooms all over.                   Facial expressions have been our way of communicating without talking. Its a silent way of showing how you feel about something or someone. Knowing what expressions are being shown towards an action you do is important. If you yell at someone, they might make an angry or upset face. After seeing that expression, most people will most likely never repeat that action again. In class rooms its hard sometimes as a teacher to teach and notice if everyone is catching along or if the subject is too boring. Having this new technology used to read students expressions is a valuable tool because it lets teachers know if they should continue or stop and help students out.
