We report findings from a study assessing computer-supported curriculum designed to engage low SES, underrepresented minority middle school students enrolled in an afterschool program with collaborative tasks that build 21st century skills, particularly related to digital literacy. Early in the program, we collected survey data from participants and from a sample of after-school attendees who decided not to enroll in our program concerning their goals, feelings toward STEM, and experiences with and access to technology. Over the first 7 weeks of programming, we also have collected attendance records. We report findings relating students’ individual factors at program onset to their attraction to and retention in our program. Our findings shed light on important issues relevant to the CSCL community and the conference theme, including identifying potential for attrition among students and engaging a diverse pool of students in computer-supported collaborative learning.
