OER/ZTC textbooks:

Baruch College’s TLC has a list of OER/ZTC textbook databases. Their site is a good place to start.

A textbook that I use is Introduction to Logic and Critical Thinking. This textbook is great for the most part. One issue with it (and indeed almost all OER critical thinking/logic textbooks) is that it doesn’t always use gender-neutral language. For example, the “straw person fallacy” is called the “straw man fallacy.” While this is perhaps a minor point, it is tiny things like this that shape gender (and other) norms in our society. To learn more about what I think about the current state of OER in philosophy, you may read this short blog post that I wrote as an Open Knowledge Fellow with the Mina Rees Library.

Nontraditional OER/ZTC teaching materials:

Professor Ann Cahill at Elon University developed a logic and critical thinking course that allows students to work through a series of cumulative, progressive steps at their own individual pace. Read this article coauthored by Ann Cahill and Stephen Bloch-Schulman in which they discuss this teaching method inspired by martial arts pedagogy.
