Can you point the way to a DIY audience response system? Answered
Audience response systems are invaluable tools in classrooms but I can't afford the $1.2K that companies want me to spend for a pack of 24 units! I've got 35+ students in my class!
Background: Electronic audience response systems allows admins to poll a large number of users on a large amount of questions.
My students (G9-12), in general, do have (newish) cell phones. (New cell phones, like new tennis shoes, are a status symbol and among even the poorest students I've seen them with new expensive cell phones). Most students do not have wireless enabled laptops/handheld computers/ accessible in the classroom. What's worse is that many school network admins flat deny student access to school's wireless for fear of security/porn/ inappropriate material etc.
The open answer/polling time would need to be able to handle responses from a variety of inputs at different times i.e. little Johnny takes a little longer than Janey to answer the question so we can't have to wait for one student to enter their response before the next student. This time delay in fact would nearly defeat the purpose of gathering responses efficiently.
I'm very interested in seeing if a blue tooth receiver/software package could handle the polling of 30+ cell phone connections at the same time.
Your help in this matter has enormous potential to achieve a Johnny Lee wiiboard like effect on classrooms worldwide.
As noted below, paper polling doesn't scale very well. If I'm performing secretarial duties of sorting paper then I'm not doing my job as a manager of a classroom and education. I feel that any teacher that is still pushing worksheets/quizzes/ etc. on paper then that teacher is working too hard and not working smart.
I've looked at trying to use off the shelf IR devices that could be used as a polling device. I believe the problem is in the IR receiver being able to identify each individual IR device. How to mod an IR so that it only has a unique signature connected to each signal?
