Most projects that create innovations in Computer Science education, whether they be changes to content or pedagogy, focus on first developing materials and then proving effectiveness. For educational innovations to have impact, however, they must be adopted by other instructors. Getting instructors to use new educational strategies is a significant challenge, with most new techniques never obtaining widespread adoption. Researchers who do consider dissemination of their research frequently use techniques such as publications and workshops, which are known to be insufficient. While there is a significant body of research on how to successfully propagate educational innovations, many CS education researchers are unfamiliar with it. Additionally, the majority of this work is from science education rather than CS education, and it is unclear how it will apply to CS. We bridge this gap by summarizing existing literature on educational innovation propagation.
