I feel like this gadget is an ideal one for me as it places some sort of responsibility on teachers and their teaching styles.
An innovation like this will help determine whether the failure is on the student's or the teacher's. As a high school student, I've had enough of certain teachers complaining about outcomes after standardized exams, i.e. the Regents, when I feel they could have done a much better job teaching and prepping us. hope this invention get into most high schools in the following years as it will be useful to administrators to evaluate teachers but more importantly, it will be a way for teachers to see their teaching styles and find ways to change or improve it to get the best out of their students.
