Our CompSci Prof. uses something built in-house by students to evaluate who understands what & whatnot in real-time too. How long is this around? Two years. Works. He uses his iPad to present his slides wirelessly to our beamer and a student voluntarily manages the polls and when enough people haven't understood a topic, the student hits a button and the slide updates the graph, then the Prof focuses on that topic a little more. That sounds more complicated than it is, it's dead easy and flawless, despite the fact that our Prof is an iDiot or iNerd, hehe :) He's just a huuge fan of everything Apple. It challenges everyone to cooperate, thankfully it's anonymous, so we can fool around too, but the Prof notices that :D In my eyes, the skill to built this is really low compared to the other stuff we've done, but it's a nice tool. Unfortunately most Prof just don't fucking care and go-on with their one-man-show. PS: Our Prof uses the stats and data generated to create the exam also ;)
