text: The reason to know how a sutdent feels in class is important or good is because the student should be paying attention to the teacher in order to learn. But something can be throwing the student off. It can be not understanding what is happening in the classroom or it can also be something inner with the student. In the passage it stated " 'A classroom computer could recognize when a student is becoming confused or bored,' Dr. Huang predicts. 'Then it could modify the lesson, like an effective human instructor.' " As said knowing how the student is the teacher can change the lesson. Although teaching how a teacher wants to teach, it's some times good for a teacher to change their way of teaching so the student can understand mor and also not to be confused. Weather it's something the teacher doesn't like to do it's better to try out new things.
