I owe Kevin Hurt at TJH a finder's fee for this week's topic. Thanks, Kevin! Socrative is a student response system that allows students to respond to multiple choice, T/F, and open-ended question that you post (or share orally) in class and they answer via a laptop, netbook, smart phone, or iPad--pretty much any device. There is no account set up required on the part of the student. In fact, once you've created your account, you're good to go--all you do is provide your students with the room number that Socrative gives you, then select the type of activity you want students to do. The "Hands On Demo" in the center of their home page does a great job of showing you the way it works from both the teacher and student point of view.
Socrative's Blog has some great ideas for how to use it. For instance, there's "3 Easy Ways to Introduce Socrative--Baby Steps" and "1-2-3 Word Cloud".
What are you waiting for? Sign up and give it a test drive with your students. Come back here and tell us what you thought. Is this a tool you could see yourself using regularly?
