This article examines whether questions embedded in geography textbooks address three components of spatial thinking: concepts of space, tools of representation, and processes of reasoning. A three-dimensional taxonomy of spatial thinking was developed and used to evaluate questions in four high school level geography textbooks. The results indicate that textbook questions focus on low-level spatial concepts more frequently than high-level spatial concepts; few questions require students to create various kinds of spatial representations; and textbook questions only rarely encourage higher-order cognitive skills. The study provides insights on the design and use of textbook questions to foster learning to think spatially. (Contains 2 tables and 5 figures.)
