Community colleges provide broad access to a college degree due to their less expensive tuition, greater course time offerings, and more open admission policies compared to four-year universities as reported (Juszkiewicz, 2015). These institutions have great potential to diversify who chooses STEM, such as engineering. Such diverse representation is important, because students from different backgrounds can contribute new perspectives that foster creative and innovative approaches to solving problems. However, approximately 40% of the students who enter community college in the U.S. leave before graduation (Xu & Jaggars, 2011). Harnessing the power of social media to reduce attrition, we tested a pilot intervention in which community college students in engineering courses completed a reflection exercise after watching YouTube videos of former engineering students from similar backgrounds who successfully transferred to a four-year college. Quasi-experimental analyses (N = 537) show that students in the intervention received higher engineering course grades and had greater odds of enrolling in an engineering course in the subsequent term compared to those who were not in the intervention. Additionally, we find support for the hypothesis that the intervention has larger benefits for women. Results suggest that hearing from other students about their engineering experience can be a useful tool for improving community college students' choices and performance.
