I came across a great news article today from Digital Trends about alternatives to Google Docs when working together online.
The article discusses the pros and cons of such alternatives as Zoho, Only Office, Dropbox Paper (what? I know...check it out), Etherpad, and Office Online.
Importantly, these office suites are FREE therefore working toward accessibility (like google docs before them) but presenting these options could also diversify students educational experience and understanding of online platforms; e.g. Zoho is made by an India-based company.
Note: some of these alternatives are only text-based (Etherpad and Dropbox paper).
If your students can't get enough of Google Docs...send them here for more information on tips, tricks and best practices
