The authors describe the development, execution, and assessment of a one-month study abroad course in London, England. Course learning objectives are discussed, linked to specific assignments, and evaluated using multiple methods. The authors highlight two team-based assignments on expertise development related to (1) navigating the London Underground and (2) aspects of London culture. Analyses focus on students' self-ratings at three time points, identification of themes in students' final reflections, and independent coders' ratings of achievement of course objectives evident in major assignments. Results indicate that students made significant improvements related to course learning objectives while also engaging in meaningful reflection about their experiences.
