text: In addition to great teachers being able to learn from themselves and their own classes without help, I believe that the software may not be able to accuratley describe all of the students facial expressions because of how many times we may change facial expressions in the duration of a class period. While some students may have the same facial expression throughout most students activley change their facial expression in multiple different ways. The Facial Action Coding System would have to activley read twenty to thirty students facial expressions activley at one time. This can also relate back the teachers not needing help from an external source because humans are engineered to read eachothers facial expressions so the teacher will already be reading the students facial expressions while teaching. This furthermore reinstates that this software is usless in the classroom.
