Google Spaces." It is an attempt from Google to keep working their way into the Social Media game. Google Spaces is essentially a "space" that you and your friends/colleagues/students can use to share links, photos and discussions. It looks similar to Google Classroom's "Stream" but it doesn't have all the features like assignments, questions, etc. What you can do with Google Spaces you can do in Google Classroom, so why use Google Spaces? I think that it could definitely serve a purpose and be used in conjunction with Classroom. Google Spaces could be used to keep your official "Classroom" work separate from the more informal sharing you could do with Google Spaces. Google Spaces is very basic, eliminating confusion about how to use it. With the Chrome extension, if you come across a great website that you want to share, you can easily use the extension to share it to your Space. You could also do this with Classroom but the more websites you find/share, the more bogged down the Classroom stream would get, thus potentially burying important announcements and assignments. I think Spaces would be a great tool for your and your students to use to find links and discuss their validity, discuss information, talk about how the site/tool could be used, brainstorm ideas, etc. You could post images and have a discussion about meaning and insight.
