We all endorse it and we all want our students to do it. We also claim to teach it. “It” is critical thinking, and very few of us actually teach it or even understand what it is (Paul & Elder, 2013). Research tells us that our students learn critical thinking only after we receive training in how to teach it and design our courses explicitly and intentionally to foster critical thinking skills (Abrami, Bernard, Borokhovski, Wade, Surkes, Tamim, & Zhang, 2008). We have to start by formulating assessable critical thinking learning outcomes and building our courses around them.
