There is a new education principle gaining traction out there called the 10:2 principle. The idea is for every 10 minutes of lecture/learning there should be a 2 minute pause for students to digest and/or share.
Well, here is a app that fits this principle like no other! Post-it Plus allows you to capture a group of post-it notes and digitize them. These could then be shared with students, different class periods, or even posted on your website. Using Post-it Plus you can allow students to share thoughts, check for understanding, and create connections.
