My Take
As a teaching tool, this is the ideal tool for flipping your classroom. It is easy to use, and you can also peruse other lessons for different subjects/teachers around the world.
How I Use It
Our middle school math teacher has used Educreations to record lessons, where students in turn can watch the videos on their iPads/MacBooks, as well as at home, which is quite useful when the student needs reinforcement regarding a lesson/topic. Thus far, it has seen the most success in the junior high math classes.
