The Impact of Undergraduate Research on Student Outcomes: Examining High Impact Practices in TBR Community Colleges. Iteration 2. Series on Student Engagement and High Impact Practices. TBR Working Papers

We investigate whether student participation in undergraduate research--a high impact practice at TBR community colleges--has an effect on (1) academic performance; (2) probability of graduation, university transfer, and student departure; and (3) time to completion, transfer, and departure. Using enrollment, graduation, and course-taking data on community college students from the Tennessee Board of Regents and National Student Clearinghouse, we track the 2017 freshmen cohort over twelve calendar semesters and examine their exposure to undergraduate research experiences and their key educational outcomes. We generate propensity scores with a machine learning algorithm and use a doubly robust inverse probability weighting estimator to mitigate the selection bias and compare outcomes of similar students among undergraduate research participants and nonparticipants. Overall, we find that undergraduate research participants demonstrate better academic performance, are more likely to graduate and transfer, are less likely to depart, and progress to transfer and departure slower than similar nonparticipants. The effects grow in size with an increase in frequency of undergraduate research experiences.
