Educreations - Use Your iPad as a Whiteboard and Record a Lesson

Educreations is a new iPad app that turns your iPad into a whiteboard. You can use the app to illustrate concepts and narrate what you're doing on the screen. You can draw images from scratch on the Educreations iPad app or you can upload images and draw on them. Your completed lesson can be shared directly to others or made public on the Educreations website.

Applications for Education
Educreations is very similar to Show Me and Screen Chomp iPad apps. All three of these free iPad apps could be used to deliver short lessons to students. You could also use these free iPad apps to have students develop and share short lessons with each other and you.
