Graduate student teaching assistants from underrepresented groups may provide salient role models and enhanced instruction to minority students in STEM fields. We explore minority student-TA interactions in an important course in the sciences and STEM – introductory chemistry labs – at a large public university. The uncommon assignment method of students to TA instructors in these chemistry labs overcomes selection problems, and the small and active learning classroom setting with required attendance provides frequent interactions with the TA. We find evidence that underrepresented minority students are less likely to drop courses and are more likely to pass courses when assigned to minority TAs, but we do not find evidence of effects for grades and medium-term outcomes. The effects for the first-order outcomes are large with a decrease in the drop rate by 5.5 percentage points on a base of 6 percent, and an increase in the pass rate of 4.8 percentage points on a base of 93.6 percent. The findings are similar when we focus on Latinx student - Latinx TA interactions. The findings are robust to first-time vs. multiple enrollments in labs, specifications with different levels of fixed effects, limited choice of TA race, limited information of TAs, and low registration priority students. The findings have implications for debates over increasing diversity among PhD students in STEM fields because of spillovers to minority undergraduates.
Enrollment increased slightly at both the California State University and University of California systems in fall 2020, but the effects of the pandemic on enrollment in the California Community College system are mostly unknown and might differ substantially from the effects on 4-year colleges. This paper provides the first analysis of how the pandemic impacted enrollment patterns and the academic outcomes of community college students using administrative college-level panel data covering the universe of students in the 116-college California Community College system. We find that community college enrolment dropped precipitously in fall 2020 – the total number of enrolled students fell by 4 percent in spring 2020 and by 15 percent in fall 2020 relative to the prior year. All racial and ethnic groups experienced large enrollment decreases in spring and fall 2020, but African-American and Latinx students experienced the largest drops at 17 percent in fall 2020. Enrollment fell the most for first-year students in the community college system, basic skills courses, and fields such as engineering/industrial technology, education, interdisciplinary studies, and art. There were smaller decreases for continuing students, academic courses transferable to four-year institutions, and business and science fields. Enrollment losses were felt throughout the entire community college system, and there is no evidence that having a large online presence in prior years protected colleges from these effects. In terms of course performance, there was a larger disruption to completion rates, withdrawal rates, and grades in spring 2020 than in fall 2020. These early findings of the effects of the pandemic at community colleges, which serve higher percentages of lower-income and minority students, have implications for policy, impending budgetary pressures, and future research.
We examine U.S. children whose parents won the lottery to trace out the effect of financial resources on college attendance. The analysis leverages federal tax and financial aid records and substantial variation in win size and timing. While per-dollar effects are modest, the relationship is weakly concave, with a high upper bound for amounts greatly exceeding college costs. Effects are smaller among low-SES households, not sensitive to how early in adolescence the shock occurs, and not moderated by financial aid crowd-out. The results imply that households derive consumption value from college and household financial constraints alone do not inhibit attendance.
One frequently cited yet understudied channel through which money matters for college students is course availability- colleges may respond to budgetary pressure by reducing course offerings. Open admissions policies, binding class size constraints, and heavy reliance on state funding may make this channel especially salient at community colleges, which enroll 47% of U.S. undergraduates in public colleges and 55% of underrepresented minority students. We use administrative course registration data from a large community college in California to test this mechanism. By exploiting discontinuities in course admissions created by waitlists, we find that students stuck on a waitlist and shut out of a course section were 25% more likely to take zero courses that term relative to a baseline of 10%. Shutouts also increased transfer rates to nearby, but potentially lower quality, two-year colleges. These results document that course availability- even through a relatively small friction- can interrupt and distort community college students’ educational trajectories.
