I’m a big believer in the multimedia classroom experience, and teaching off a tablet gives me the opportunity to mix audio and video with texts as my students explore skeptical tools and critical thinking concepts. As you might imagine, I’ve accumulated quite a collection of classic and current material, most of it readily available online somewhere. It’s an ongoing project, and every so often I like to cast around for some gems I’ve overlooked or some old favorites I’ve forgotten.
So I’m putting it out to the crowd: What article, video or graphic would you consider indispensable in a course on skepticism or critical thinking? (Bonus points for providing a link and a brief explanation of the concept or skill demonstrated.)
