QUIA – A powerful course management system online
This service is worth having a go at. You can build a class webpage easily, set games and activities and assess quizzes. There is a free 30-day trial for teachers. If you decide you like it, it’s US$50 per year, per instructor account. Students, however, can use it for free and once they’re logged in can access a lot of resources from any discipline.
Here is an example page – it took an hour or so to set up and the quizzes took about an hour each.
