text: However, there is one clear down set to this idea, and thats that if kids need to be facially monitered to know if they enjoy the class or not, then it's probably the teachers fault. Yes reading emotions would be a cool feature to add to know if students are enjoying what they are learning, but it will probably be an expensive technology to purchase. Furtherly noted, also stated in Making Mona Lisa Smile, we don't completely communicate with each other through words, so it wouldn't exactly be an impossible thing for teachers to realize if they're being boring if they pay attention to how the students are reacting to what they are teaching. It just seems as though it is an unnecessary piece of technology that many want entered into the classroom setting.
