I like this article as it shows a few things: 1) Alternative teaching/thinking outside the box for a personalize experience. 2) It's a good use of gamification in learning. 3) There is some flipped classroom learning going on as well. Having a son who is Asperger's and recently asked to go on Minecraft after participating on Roblox for a long time, I'm thinking it might be worth the investment. While he can read very well, and he has good ideas, his writing needs some help. Perhaps this might be the key for him or others who need a differrent way of learning.
