Integrating Videos with Programming Practice

There is an increasing variety of tools available to support students outside of the classroom as they learn how to program. However, broadening participation in computer science will also require these tools to reinforce inclusivity, diversity, and equity. To address these needs, two Hispanic-Serving Institutions, California State University, Chico (Chico State) and University of California, Santa Barbara (UCSB), are collaborating to produce video tutorials featuring students from historically marginalized communities. In these videos, students demonstrate uses of programming concepts in contexts that relate to their lives and interests. This experience report describes the development of the videos and associated programming practice problems. In a mixed-method observational study (n=188) of CS1 courses at the two universities, we investigated students' engagement with the videos and practice problems. Preliminary findings revealed that when the videos and practice problems were provided as separate links, students tended to watch the videos but not engage in the practice platform. Consequently, this paper also describes the development of Codewit.us, which integrates video lessons with an adaptive drill-andpractice programming interface. We found that when presented with the integrated interface, students were more likely to engage with practice in tandem with watching videos (instead of just watching videos without practice, as previously observed). The paper also describes thematic analysis of students' qualitative feedback on the videos and practice problems.
