text: So, no I don't think it's classroom valuable to use FACS. But that dosen't mean that you should not let them try it. Here's what the teachers should do. They show the students a picture of someones face. Lets just say for example Mona Lisa. The students will stare at the picture for about a minute carefully looking at every part of Mona Lisa's face. Then the students will decide Mona Lisa's emotion by rating her happiness, sadness, anger, digust or any other kind of emotions. Then after that the teacher uses the FACS on Mona Lisa's face to see if the results for Mona Lisa's emotions from the technology is the same as the results from the students. Human vs Technology there you go.                                  Dear Mr. Senator,
