I mentioned previously the need for professors to get students to spend less time reading Wikipedia and similar sources, and more time writing Wikipedia, contributing reliable information based on other reading they’ve been doing.

And so the students in my course on the Book of Revelation this semester have been contributing to the Wikibooks commentary on the Book of Revelation in lieu of writing overnight short writes. You can pay a visit to the site and see the results.
(I actually tried this once before, in my class on the Gospel of John a few years ago).
