Google summer of code: Student motivations and contributions

Several open source software (OSS) projects participate in engagement programs like Summers of Code expecting to foster newcomers’ onboarding and receive contributions. However, scant empirical evidence identifies why students join such programs. In this paper, we study the well-established Google Summer of Code (GSoC), which is a 3-month OSS engagement program that offers stipends and mentorship to students willing to contribute to OSS projects. We combined a survey (of students and mentors) and interviews (of students) to understand what motivates students to enter GSoC. Our results show that students enter GSoC for an enriching experience, and not necessarily to become frequent contributors. Our data suggest that, while stipends are an important motivator, students participate for work experience and the ability to enhance their resumés. We also discuss practical implications for students, mentors, OSS projects, and Summer of Code programs.
