STEM BUILD at UMBC is funded by the National Institutes of Health (NIH) and is a study investigating how best to support the success and persistence of students majoring in science, technology, engineering, and mathematics (STEM). A major focus of STEM BUILD at UMBC is scalability, as the goal is to institutionalize the interventions that promote student success and persistence. There are three main Cores of STEM BUILD at UMBC: 1) Student Training Core, 2) Research Enrichment Core, and 3) Institutional Core. The Student Training Core employs randomized control trial methodologies with matched pairs. Exemplars of the Student Training Core are participants in the BUILD Training Program, who are provided financial support in addition to holistic academic advising, unique educational and research experiences, residence in the STEM Living and Learning Community, and other programmatic support. The BUILD a Bridge to STEM Internship is the flagship program of the Research Enrichment Core. The BUILD a Bridge to STEM Internship is a six-week group research experience in the summer for students enrolled at local community colleges (Anne Arundel Community College, Community College of Baltimore County, Howard Community College, Montgomery College, and Prince George’s Community College), Gallaudet University, and Morgan State University. Students in the BUILD a Bridge to STEM Internship work in teams of three on authentic research experiences mentored by UMBC faculty or industry partners and the internship is being used as a model to increase the number of students who engage in undergraduate research. Finally, the Institutional Core is exploring mechanisms to increase active learning and pedagogical innovations within STEM education through the development of the Active Learning and Inquiry Teaching (ALIT) certificate, which educates faculty on evidence-based teaching methods.
