instant feedback (Score 1)

I'd like to see technology used to give students and teacher immediate feedback on the teacher effectiveness. Use of a few questions at the beginning and/or end (or as needed) can assist in knowing if you are getting the message though. Students need an easy way to input answers like those programmable cheap tv remote controls. Software to collect student inputs and display results real time. An overhead IR reader to collect the inputs. With instant feedback the teacher knows if the homework was effective, the concept understood and who needs to come in after class for help and with which concept.
