Distance Learning Courses Database?

Hi!

I'm new to degreeinfo, and I would like to know if there are online databases featuring all distance learning courses in the US and Canada.

I used to rely on petersons.com, but aparently they now focus only on degrees, not courses.

I am particularly interested in courses in critical thinking, argumentation, reasoning skills, logic, writing, and maths.

Thanks a lot for your advice.
