"What it is: IDroo is an educational multi user whiteboard that lets students instantly collaborate online.  Everything that is drawn or written on the whiteboard is visible to all participants in real-time.  IDroo supports an unlimited number of meeting participants, the only limitations are computer power and internet connection speed.  There is a professional math typing tool built-in making it easy to teach or work through math problems collaboratively. Best of all, IDroo can be used with Skype! IDroo is free for non-commercial use. Now for the downfall (and this is a HUGE downfall in my humble opinion), IDroo is currently only available for Windows.  I  know, disappointment for us Mac lovers. *sigh*  If you are using a Windows computer this is a great way to collaborate online! How to integrate IDroo into the classroom: IDroo would be a great app for collaborating with other classrooms around the world.  Students can use the multi user whiteboard space to work together, share ideas, and brainstorm.  IDroo would also be fantastic as a way for teachers to tutor students virtually.  Set up an "open lab" time once a week online where students can drop in and get extra help.  Virtual lab times are especially helpful for elementary students who can't dictate their own schedules and often can't stay after school for extra help. Tips: Don't forget to allow IDroo to access Skype API after you download!" iLearn Technology
