Socrative is a Student Response System on the Phone
Socrative is an app that you can get on the iPad or Smartphone that turns their device into a student response system. You can post questions, and they can answer, and you get real time data that you can collect.
It's great because it forces all of the students to participate, and you get data for all students.
