I simply want a page where in class, -5 Studnts can be working on the same page with different computers. You can do this in Google docs, but can I do this in Wiki, using collaborative wiki?
What is the closest I can come to doing this in Moodle?
You can do this in a collaborative wiki yes; you can also do this with the contributed plugin "real time collaborative editor". Google docs does do this very well though; I must confess.
A link to that plugin is at: http://moodle.org/mod/data/view.php?d=13&rid=4621
Interesting tool.
<EDIT> NOTE: This is another amazing tool written by Juan Leyva. He is doing some amazing stuff.
