How
can I work together on text documents?

Here you will find a tutorial on how to work together on presentations. The procedure is the same for documents, except that you create a new document or upload one.
You can then share this document with your fellow students, just as described in the tutorial for collaborative work on presentations, and can follow changes to the document live.
Alternatively, you can also use Office 365 online.
