This weekend, the White House invited game developers to come and make educational games. It was a 48-hour jam that tasked developers with making games in different subject areas that adhered to the Common Core standards in children's education."Let's encourage our kids and push ourselves to become ambassadors for game-based learning. Let's curate and share examples of games that are difficult and reward the kind of critical problem-solving 'academic' tasks often do not. Let's make do until we make a better future for games in the classroom and a more purposeful and critical community of gamers and game makers in our schools," writes Chad Sansing, the education advisor for the game jam, in a kick-off blog post The event hosted developers from big studios ( Rovio and Ubisoft's Red Storm were involved) and independents, too, along with government figures and educators.There a wealth of tweets from the event under the #WHGameJam tag -- which cover everything from videos of submitted games to photos of the event and commentary, too.
