ClassDojo has added new feature that teachers have asked for, a timer. The timer is available to you when you're viewing a class in your web browser (it's not in the iPad app). The timer has a countdown and a count-up mode. The video below shows you how it works.
Applications for Education
Over the last year I've heard from a lot teachers who love ClassDojo. One good use of ClassDojo is projecting the "positive behaviors only" screen while giving out positive recognition at the end of the school day. I've also had a conversation with a high school teacher who is using ClassDojo as a way to award points for participation in classroom discussions as the discussion are happening. And if students are logged-in to their accounts they can track their progress too.
