MinecraftEdu -- which Microsoft bought -- was created by teachers, so you'd get some info from its various blog posts at http://minecraftteacher.tumblr.com/
Otherwise, there are lots of articles about teachers using it for maths, history, geography, English etc.
Trust the teachers. This is the bottom-up adoption by schools who find Minecraft useful. There hasn't been any top-down pressure from governments, teacher training organizations or commercial companies.
A lot of kids playing Minecraft will someday wonder what the awesome language/platform is used to build my favorite game. Microsoft wants to be a big player in the answer and outshine Java. That is the education part you are looking for. Educating how great Microsoft technology is.
