Teach Thought is a blog and podcast focused on professional development for teachers. The content can skew a little K-12, but there are still some very insightful pieces for teachers working in higher education.
50 Questions To Help Students Think About What They Think is a list of questions to use in the various academic disciplines to help students develop metacognition and critical thinking abilities. Some of the literary questions (If you were this character, how would the story change? How would you change the end of the story and why?) might be of interest to teachers working with literature in their classes. Likewise, some of the scientific questions (How can you justify this information? What are some of the complexities we should consider?) are great for guiding students through a piece of persuasive writing or a research project.
