This study assesses the impacts of the Science program at Piedmont Virginia Community College and its flagship capstone research experience, Supervised Study, through psychosocial perceptions associated with persistence in science and through a comparative analysis of subsequent science bachelor’s degree attainment. Supervised Study involves authentic, independent projects, a research methods course and learning community, and one-on-one faculty mentoring. The Persistence in the Sciences survey was used as a repeated-measures instrument in four semesters of Supervised Study. Positive trends were observed for self-efficacy, science identity, community values, and networking, while responses related to project ownership were mixed ( n = 13). To contextualize these observations, transfer and bachelor’s degree completion rates were analyzed. Students who earn an associate’s degree in Science ( n = 113 between 2012 and 2019) complete bachelor’s degrees at high rates (66.4%). Moreover, they are two to four times more likely to major in physical and natural sciences than their science-oriented peers, who take many of the same courses, with the exception of Supervised Study. Notably, these comparison rates remain consistent between different demographic groups. These findings further describe a model for research at the community college level that supports persistence in undergraduate science for a broad group of students. 

Millions of dollars each year are invested in intervention programs to broaden participation and improve bachelor degree graduation rates of students enrolled in science, technology, engineering, and mathematics (STEM) disciplines. The Virginia–North Carolina Louis Stokes Alliance for Minority Participation (VA-NC Alliance), a consortium of 11 higher education institutions and one federal laboratory funded by the National Science Foundation (NSF), is one such investment., The VA-NC Alliance partners implement evidence-based STEM intervention programs (SIPs) informed by research and specifically designed to increase student retention and graduation rates in STEM majors. The VA-NC Alliance is conducting an Alliance-wide longitudinal research project based in Social Cognitive Career Theory (SCCT) titled “What’s Your STEMspiration?” The goal of the research project is to assess the differentiated impacts and effectiveness of the Alliance’s broadening participation efforts and identify emergent patterns, adding to the field of knowledge about culturally responsive SIPs. In other words, “What’s Your STEMspiration?” explores what influences and inspires undergraduates to pursue a STEM degree and career; and how does the development of a STEM identity support students in achieving their goals. In order to complete this research, the research team developed a survey instrument to conduct the quantitative portion of the study. Two preliminary studies, statistical analysis, and cognitive interviews were used to develop and validate the survey instrument. This paper discusses the theoretical and conceptual frameworks and preliminary studies upon which the survey is built, the methodology used to validate the instrument, and the resulting final survey tool.
