Screen Chomp is a very simple to use tool that allows teachers and students to make simple video tutorials on their iPads and upload them to the web to share with others.
It is a great tool for teachers who might wish to explain how to do perform a mathematical equation so that their students can reference it at home. Students can also respond to the screen casts and share it on social media.
The short video below will give you a far great overview of its potential in the classroom.
There are a number of screen casting solutions on the iPad already, but this is made by TechSmith who dominate the screen casting world on Mac and PC already and this product has all the polish of those products too.
Screen Chomp is a free app that is only available on the iPad currently and can be accessed here.
