Through an instructional approach, this article offers a template for a classroom-based geography capstone course grounded in pedagogical elements of synthesis and reflection, as based on exploration of ten key geographic ideas. It provides insights into course goals, structure, and components for instructors who may wish to implement it in geography or in other disciplines, and it situates the template in the general structure of capstone courses detailed in social science literature. The article contributes to geography instruction with a focus on classroom-based capstone courses as an application of teaching and learning undergraduate geography. (Contains 1 note.)
