Team composition is a critical factor influencing collaboration in agile software development. This study investigates the impact of gender distribution on teamwork quality in software engineering capstone courses. We examined the experiences of 240 students organized into 40 teams during an agile project course. We analyzed two surveys, one conducted before team composition and one at the end of the project work. Our analysis reveals that while women tend to engage more in design and men in programming, an increase in the proportion of women within a team correlates with a higher involvement of women in programming tasks. Additionally, women reported dedicating more hours to the project and exhibited greater satisfaction with stand-up meetings than men. Our findings highlight gender differences in perceptions and experiences related to project involvement in agile software engineering courses.
