This chapter discusses making thinking visible in the classroom. It defines thinking as involving various processes beyond just memorization, including understanding, reasoning with evidence, perspective taking, and questioning. The author argues Bloom's taxonomy is too linear and that understanding results from applying, analyzing, and evaluating information, rather than being a precursor. The chapter also outlines different types of thinking teachers should aim to engage students in, such as pattern identification, perspective taking, and self-regulation. It concludes by discussing the importance of developing students' metacognition and awareness of their own thinking processes.
