According to Google's blog, The Keyword, teachers and students have been testing this new feature for the past few weeks. Google points to 3 specific use cases in its post. The first is an adult course on graphic design using Google Drawings (a good opportunity for cross-promotion there). The second involves after school programs, in this instance a girl scout group dedicated to building robots. And lastly, it talks about a student-run club intended to bring together those wanting to discuss design, art, and programming.
It looks like it would be perfect for various adult education programs not affiliated with a school and it's great to see Google making these types of educational resources available to more and more people. Download the app below, or take a look online, to see if there's anything interesting you'd like to learn.
