text: Students go through a lot with life-changing tests, and pressures to be successful in life. With the FACS, teachers will be able to sense when a student is unwilling or not trying; teachers will know to not waste valuable time on them. These types of attitudes are contagious especially in a classroom. According to the Facial Feedback Theory of Emotion, we unconciously imitate eachother´s facial expressions and moods. This means other students won´t want to learn either.
