This experience report explores the effects of ungraded assignments on the learning experience of students in an introductory computing course. Our study examines the impact of ungraded assignments on student engagement, understanding, and overall academic performance. We developed and administered new ungraded assignments for a required course in the first year of the Computer Engineering curriculum called ECE 120 Introduction to Computing. To assess the effectiveness of our ungraded assignments, we employed a mixed-methods approach, including surveys, interviews, and performance analysis. Our analysis shows a positive relationship between participation in ungraded assignments and overall course performance, suggesting these assignments may appeal to high-achieving students and/or support better outcomes.
