This paper describes an exploratory study to identify which environmental and student factors best predict intention to persist in the computer science major. The findings can be used to make decisions about initiatives for increasing retention. Eight indices of student characteristics and perceptions were developed using the research-based Student Experience of the Major Survey: student-student interaction; student-faculty interaction; collaborative learning opportunities; pace/workload/prior experience with programming; teaching assistants; classroom climate/pedagogy; meaningful assignments; and racism/sexism. A linear regression revealed that student-student interaction was the most powerful predictor of students' intention to persist in the major beyond the introductory course. Other factors predicting intention to persist were pace/workload/prior experience and male gender. The findings suggest that computer science departments interested in increasing retention of students set structured expectations for student-student interaction in ways that integrate peer involvement as a mainstream activity rather than making it optional or extracurricular. They also suggest departments find ways to manage programming experience gaps in CS1.

Undergraduate research experiences are promoted and funded for their potential in increasing students’ likelihood of pursuing graduate degrees, increasing their confidence, and expanding their awareness of their discipline and career opportunities. These outcomes, however, depend on the social, organizational, and intellectual conditions under which students conduct research. Large-scale comparative studies suggest that computer science undergraduate researchers participate in fewer of the activities that lead to membership in a “culture of research.” This interview-based study illuminates the experiences of both undergraduates and their faculty research mentors in computer science summer and academic year programs. Twenty-five undergraduates and 31 faculty mentors, the majority women, were interviewed. Their stories reveal best and worst case research conditions for students, the special benefits to women who have experienced harassment in their classes, unconscious biases of faculty, the wisdom of faculty who guide undergraduates to successful research outcomes, and faculty’s perceptions of benefits for themselves, their departments, and the students they mentor.
