text: The use of the Facial Action Coding System i dont't really think it's valuable in the classroom because i dont't thnk students want people to know if they are feeling any kind of depression,I mean the machine is amazing and all but i don't think students would want to hear about how they feel when they know because it'll just make them even more upset to hear it. The system could be useful anywhere else but in a classroom i don't think it should be used there unless there were students that weren't feeling any depression or anger maybe they would just want to try it out just for the fun of it.
