  2. Although designed to prepare students for future coursework or to fulfill basic degree requirements, introductory math courses often serve as barriers to student success. In two double-blind randomized field experiments, we tested the efficacy of a utility-value intervention on improving community college students’ perceived math relevance and achievement in introductory math courses. Building upon prior research, we examined whether the intervention particularly benefited first-generation and racially marginalized students. Study 1 (N = 696) was conducted before the COVID-19 pandemic and within in-person classrooms, whereas Study 2 (N = 1,318) was conducted during the pandemic and within virtual learning environments. Across Studies 1 and 2, students in the utility-value condition benefited more in terms of their perceived relevance compared to their peers in the control condition. Additionally, in both studies, math relevance mediated the effects of the intervention on math grades. In Study 2, with a larger sample, the positive effect of the intervention on math relevance was more pronounced for first-generation students. Our findings imply that community colleges could significantly improve students’ academic experiences by investing in motivation-enhancing activities such as utility-value interventions in introductory math courses. This strategy could especially help first-generation students’ academic achievement and retention rates.

    Researchers often invoke the metaphor of a pipeline when studying participation in careers in science, technology, engineering, and mathematics (STEM), focusing on the important issue of students who “leak” from the pipeline, but largely ignoring students who persist in STEM. Using interview, survey, and institutional data over 6 years, we examined the experiences of 921 students who persisted in biomedical fields through college graduation and planned to pursue biomedical careers. Despite remaining in the biomedical pipeline, almost half of these students changed their career plans, which was almost twice the number of students who abandoned biomedical career paths altogether. Women changed plans more often and were more likely than men to change to a career requiring fewer years of post-graduate education. Results highlight the importance of studying within-pipeline patterns rather than focusing only on why students leave STEM fields.
