"Enhance learning with Present.me by providing not just a friendly face, but some great content to go with it. As a teacher, you can use our product for the 'flipped classroom' model to give a recorded lesson on Present.me, which students can then watch in their own time, over and over again if they so desire.
This leaves you extra time in class for more interactive work. Or why not submit a Present.me to students after a class to help reinforce a key point or idea?" from source: https://present.me/
