ClassDojo is a great site for keeping track of all the little things that your students do, good and bad. I am currently reviewing the site and app and I will update this post once I have finished.
(March 17, 2013 update) I have been using this app/site for a few weeks now and I am impressed. The kids have liked it and it has been easy to work with as I move around the computer lab. I had the opportunity to share it with some of my fellow teachers and a few have expressed some interest. I hope that they have nothing but success and I hope they have stories for me about how they use it to help me use it better in my classroom.
