This is a really cool video of a teacher who turned his classroom learning environment into a video game, including gaming elements such as "levelling up", activities, and videos. His students were able to learn their materials through videos and online lectures, and then apply what they had learned in in-class experiments and labs.

What's really awesome about this video is how he comments on his failures, acknowledging that his idea isnt flawless yet, and is still going through developments and modifications.
