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 introductory computing course in the first year of the computer engineering curriculum. To assess the effectiveness of our ungraded assignments, we employed a mixed-methods approach, including surveys, interviews, and performance analysis. Our analysis reveals a positive correlation between participation in ungraded assignments and overall course performance. However, this relationship appears to reflect pre-existing student motivation rather than the direct learning effects of the assignments themselves.
