My two younger daughters are crazy about Minecraft. Minecraft allows them to creative and use critical thinking skills. They collaborate on projects with their peers. Minecraft is also a great social outlet. My daughter who is on the autism-spectrum and has social anxiety becomes socially animated chatting with friends while on Minecraft. Beyond the game itself, Minecraft has inspired them to want to learn more about coding. They are also checking out both fiction and nonfiction books from the library about and inspired by Minecraft.
As a future librarian, I would support the use gaming technologies, such as Minecraft, at the library. I feel that there are definetly educational benefits from this game.
Here are some interesting articles on how teachers (and librarians!) can use Minecraft for educational purposes.
