Priming the Pump or the Sieve: InstitutionalContexts and URM STEM Degree Attainments Sylvia Hurtado Kevin Eagan Bryce Hughes Higher Education Research Institute, UCLA
National Academies (2011) report Expanding Underrepresented Minority Participation: America’s Science and Technology Talent Establishes most of the growth in the new jobs will require science and technology skills “Those groups that are most underrepresented in S&E are also the fastest growing the general population” (National Academies, 2011, p. 3). In an effort to achieve long-term parity in a diverse workforce, they recommend a near term, reasonable goal of improving institutional efforts to double the number of underrepresented minorities receiving undergraduate STEM degrees. A National Imperative
A National Imperative • 2012 President’s Council of Advisors on Science and Technology (PCAST) report, Engage to Excel: Producing One Million Additional College Graduates With Degrees In Science, Technology, Engineering, And Mathematics • Increasing the retention of STEM majors from 40% to 50% would, alone, generate three-quarters of the targeted 1 million additional STEM degrees over the next decade. • Retaining more students in STEM majors is the lowest-cost, fastest policy option to providing the STEM professionals that the nation needs. • Changing productivity levels means changing practices, and mindsets from priming the sieve to priming the pump, or talent development.
Purpose of the Study • Identify the faculty and institutional characteristics that contribute to higher rates of STEM degree completion, particularly among underrepresented groups, controlling for students’ entering characteristics. • Identify challenges and opportunities to prime the pump and improve the use of “evidence-based” approaches.
Literature Review: Student-level Characteristics • Pre-college experiences • Strong high school curriculum • High test scores and grades • Advanced courses in science and mathematics • High aspirations for a STEM degree • URM students less likely to access AP courses, yet equally or more likely to aspire to a STEM degree
Literature Review: Institutional-Level Characteristics • Faculty pedagogies • STEM courses tend to utilize teacher-centered pedagogies • Introductory STEM courses perceived as “gatekeepers” to STEM degrees • Student-centered pedagogies key to retaining women and URM students in STEM programs • Minority-targeted STEM retention programs • Generally improve probability of URM STEM degree completion • Mixed results regarding improving URM academic performance • Undergraduate research experiences • Found to be one of the most effective contributors to increasing URM STEM completion odds • Benefits to students participating in undergraduate research may be conditional depending on timing and duration • Minority-serving institutions (MSIs) • HBCUs in particular provide a unique atmosphere that supports Black students’ degree attainment • Research is beginning to demonstrate benefits for other URM students attending other categories of MSIs
Literature Review: Are Selective Institutions Better for URM Students? • More selective universities have higher graduation rates • URM students also graduate at higher rates from more selective institutions • More recent studies have found conditions that indicate this benefit does not apply across the board • Wider usage of multilevel modeling in higher education research has shown single-level modeling overstates the effects of selectivity • Selectivity was found to be negatively related to four-year retention of women of color in STEM • Biomedical and behavioral science students attending more selective institutions were slightly but significantly less likely to be retained in these programs to their fourth year • Yet many recent multilevel studies continue to confirm selectivity positively predicts higher probability of graduation
Data Source: 2004 Freshman Survey, 2010-11 National Student Clearinghouse; HERI, UCLA
Method • Longitudinal Data on STEM Aspirants • Individual level: 2004 Freshman Survey, CIRP merged with completion data from the National Student Clearinghouse • Sample: 58, 292 students across 353 institutions • Faculty Data: 2007 & 2010 HERI Faculty Survey from 659 institutions, with STEM Supplement for over 10,000 STEM faculty • STEM Best Practices Survey – administered to STEM deans and department chairs at our participating campuses • Institutional Data obtained from IPEDS, Aggregates of Faculty, and Aggregates of Peer characteristics from students entering the same institutions in 2004.
Method • Dependent Variable: • STEM completion compared to: • Bachelor’s completion in non-STEM field • No bachelor’s degree completion-includes students still enrolled (major not known) • Measured at four, five, and six years to reflect differences in time to degree
Method • Independent variables • Background characteristics • Pre-college preparation and experiences • Aspirations and expectations • Intended major • Aggregate peer effects • Institutional characteristics • Faculty contextual measures • Best practices in STEM
Method • Analysis • National weights • Missing data with multiple imputation • Multinomial HGLM • Limitations • Intended rather than declared major • NSC data – no information on term-to-term major • No college experience measures • Few high school preparation variables • BPS data reported by STEM Deans and Dept. Chairs
Key Findings for Four Year Completers: STEM vs. Non-STEM • Denser concentrations of MD aspirants and larger campuses negatively predict STEM completion • Differences by race • Latino (-), Black(ns) • Asian/Pacific Islander (+) • Other race (+) • Women (-) • HS grade (+), and effect enhanced by faculty use of student-centered pedagogy • SAT, years of HS math and biology (+)
Key Findings for Four-Year Completers: STEM vs. Non-STEM • MD aspirant (+) but effect mitigated by faculty grading on a curve and selectivity (-) condition • Ph.D./Ed.D. aspirant (+) • Law degree aspirant (-) • Engineering, physical sciences, health tech/nursing, and computer science (+) • Pre-med, pre-pharm, pre-dental, pre-vet (-)
Key Findings for Five-Year Completers: STEM vs. Non-STEM • Drop in predictive power of institutional size • Non-sig difference between Latino/other groups and White students • Decrease in gender gap • Decrease in salience of SAT • Decrease in gap between BA/BS aspirants and law/medical aspirants • Changes regarding majors • Engineering increased gap, more likely to complete in 5 years • Physical science, health tech/nursing, and computer science gap decreased compared to biomedical aspirants

Conclusion Contexts Matter Selective institutions can improve productivity. They promote degree completion, but students are not more likely to complete in a STEM degrees. Premed Phenomenon Students who begin premed at institutions are more likely to complete in STEM, are less likely to complete in STEM at selective institutions, high % of premeds causes students to switch from STEM among four year completers—presumably a talented group.
Conclusion Supportive Environments Work! • Minority engineers are more likely to be retained in STEM if they complete college compared to bioscience aspirants. • Having an undergraduate research program has an effect on retaining minority students in STEM (and quicker degree completion). • Faculty student centered pedagogy was important to staying in STEM for high-achieving minority students. • Grading on curve particularly hurt premed aspirants, they were more likely to leave STEM at institutions where used.
Conclusion • In order to produce 1 million more STEM degrees, we have to address diversity and equity in attainments and improve access to STEM careers. • Call for evidence-based teaching practices in STEM. • New initiatives by AAU and APLU indicate great interest in “demonstration campuses” that can make transformations to increase productivity of STEM degrees.
