Hi, I have been using clickers to test comprehension while I'm doing my lecture. This is of course, when I need to do a lecture to cover some material. Since the school does not have a clicker system, I have been using a free system from Socrative.com . It is a multi platform application that runs on android, iPhone, tablets, and any cell phone or laptop that has a browser. It's still in beta for the moment, so it's free to try out and it has some very cool games that you can create using quizzes. Personally, I prefer using the Beta version of the software that's available here: beta.socrative.com It's my first week on the listserv and I was able to post something that might help somebody! Awesome! I love all of the tips and the conversation that comes through here! Thanks! Paul Benedict IT and project management
