There are a few sites around the web that host Moodle courses available for download.
- MoodleCommons http://moodlecommons.org/
- MoodleShare http://courses.moodleshare.com/
- Moodle http://moodle.org/mod/glossary/view.php?id=918
- Demo Moodle http://demo.moodle.net/
Between them there are over 100 courses available to download and restore to your Moodle site (sweet).
That being said; there are only 100 Moodle courses out of over 3 MILLION (not a very good ratio; http://moodle.org/stats/).
We must be missing some, if you know of a site where even just one course is available for teachers to browse and possibly download let us know using the form below. You’ll be able to see the results once you share you link. When all is said and done we’ll share the results of the survey in a few weeks and hopefully we’ll be able to point to a good many additional courses available.
