text: I think this new technology to read the emotional expression s of students of students in a classroom is valuable because a teacher can tell if you are confused or board. In the article, the author states that "then it could modify the lesson, like an efective human instructor". I believe this is true because it could help the teacher know who doesn't understand what they are teaching. It could also tell the teacher who needs it explained in a different way to help them understand it better. Having technology that can tell if a student is confused or board would have value becasue it could help teachers know which of their students are understand what they are teaching and which ones aren't.
