Reddit reviews Critical Thinking, Reading, and Writing: A Brief Guide to Argument

I've got to go for a while and I'll say more later, but one thing to do is just google "critical thinking syllabus" and you'll come across a few syllabi. Take a look at those and I'll give you some more advice later.

Here's a couple I found that were good: http://staff.kings.edu/jmwallac/thinking/index.htm

Also if you go to Amazon and look for critical think textbooks Amazon will sometimes let you peek inside and look at the table of contents for the book. That will give you some idea of the things covered in a typical critical thinking class.
