Although student self-assessment is considered a critical component of assessment for learning, its use and related research are rare in higher education. This article describes an action research study of self-assessment as an instructional strategy in two university courses. Results indicate that self-assessment exercises provided students the opportunity to reflect on the course and their performance, helped them monitor their own progress, motivated them to do well in the course, and provided them the opportunity to give feedback to the instructor. Additionally, from the instructor perspective, the exercises provided useful feedback for course improvement and facilitated interactions and relationships with students.
