text: Many parents do benifit from this great advantage becuase the student can take a class knowing that the parent will give suport to the kid in his or her future carrer. I think the use of techology than can read the emotional expressions of students in classroom is valuable. Technology would be able to make see and predict more student's emotions. Knowing the emotions of students would allow changes to be made in the teaching of individual students. With technology, classrooms would be more effiecient, have better test scores and grades and would allow for a better development in education.
