text: The Facial Action Coding System is a bad idea for the classroom, as it could incorrectly read a student's emotions and give a misleading output that puts a student off track in their education, and also because it could invade a student's privacy of their inner mind. Therefore, installing this system in schools would be a waste of money and recourses, especially when teachers can gauge how their students are learning by simply asking their students in an anonymous survey how they feel about their teaching methods. In this society, technology is used to fix almost everything, but in this case, scientists should quit trying to force technology on behavioral issues and just let humans interact so they can benefit themselves with communication, no computerized middleman needed.Dear, Principal what's your face
