text: Using the Facial Action Coding System to read the emtional expressions of students in a classroom is valuable because it allows students to learn better. In the article "Making Mona Lisa Smile" by Nick D'Alto it says that the system could "modify the lesson, like an effective human instructor". All students would be able to get helped individually, one on one with the system. The system also allows students to learn better because everyone learns things differently, and the system would be able to adjust for every student's learning style. In the article it says that the system can detect if a student is confused, so the system would be very valuable in classrooms because it would make sure that students are not confused. The system would make sure that students are actuallly comprehending the material.
