Geddit is a free service for quickly gathering feedback from your students through any web-enabled device. I initially reviewed the service back in March. Since then Geddit has added a couple of helpful new features. First, you can now comment and send messages directly to individual students through Geddit. This feature will allow you to follow-up with a student who replied "I don't get it" to a question.
The other new feature of Geddit that teachers will like is the personalized Review Page for students. On their personalized Review Pages students can review topics covered in class, revisit areas of concern, and see your personal comments about their responses to your Geddit prompts.
If you haven't seen Geddit before, it gives you the ability to push questions to your students' devices. You can create and send multiple choice and short answer questions. You can also simply ask "do you get it" at any time to check for your students' general feelings about a lesson you're conducting. The feedback that you gather from your students through Geddit can be displayed in a variety of graph and list formats. The list format that I like best shows me how each student responded to my "do you get it" question and highlights the students who responded with "no" or "kind of."
Applications for Education
Geddit was already trying to distinguish itself in the student-response system field by providing a wide variety of data collection formats. The new messaging option and student Review Page option give another distinguishing aspect that can improve the way that you collect and work with student response data.
