This mixed methods study examines an explanatory video assignment designed to operationalize contemporary theory about cognition, metacognition, and inclusive teaching. This project grew from a professional learning community of post-doctoral teaching fellows who were involved in course redesign as part of a campus-wide active learning initiative. A team of pedagogical experts, teaching fellows, and faculty designed this video assignment to increase opportunities for students to share their perspectives while practicing a powerful learning strategy. Instructional teams implemented different versions of the video assignment in three courses across two departments. An experimental research component isolated the impact of the assignment on learning and confidence, and a mix of quantitative and qualitative analyses provided evidence about students’ experiences with the assignment. We found that students expressed learning and confidence gains beyond those due to typical course activities. Qualitative evidence suggested that students experienced the assignment as valuable for their learning and that the assignment enhanced self-expression. The assignment was effective in both face-to-face and remote settings, implemented either as a course requirement or extra-credit option. This versatile video assignment presents a practical way to enrich the student experience.
