After Microsoft bought Minecraft, it announced in January that it would be releasing a new version of the game specifically geared toward using in the classroom. Now there are more details.

A Beta version of Minecraft: Education Edition will be available in May for more than 100 schools across 30 countries, Microsoft announced. After processing feedback from the Beta, an early access version will be available in June in 11 languages and 41 countries. Both versions will be available for free, in exchange for user feedback.

I’ll admit to being a bit skeptical about using Minecraft as an education tool, but it sounds like it’s been a really powerful asset for educators.

“In 2011, educator Joel Levin developed MinecraftEdu,” EducationWorld reports. “Not long after, the potential for Minecraft in the classroom was realized when the program expanded to over 5,500 educators and received support from Minecraft’s former owner, Mojang.”

A handful of lessons are available on Minecraft: Education Edition‘s website and range from exploring the pyramids at Giza to learning about electrical engineering.

The early access program launching in June “will continue throughout the summer, while Microsoft also teams with these early adopters to build out lesson plans, share learning activity ideas, and create re-usable projects,” TechCrunch reports.

CNET notes that Mojang originally developed Minecraft using Java, which made it fairly easy for users to write their own mods for the game. However, newer version of Minecraft, including Education Edition, are written using C++, which means no mods — at least not right away.

“Microsoft plans to bring mods and command blocks — another key way to tweak Minecraft — to the next C++ version,” CNET reports.

Minecraft: Education Edition will run on the latest version of Windows 10 and Mac OS X El Capitan. Users will also need to sign up for a free Office 365 Education account.

So far, there’s no word in prices for the final product.
