A National Imperative 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 Imperative2012 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

ConclusionContexts MatterSelective institutions can improve productivity. Theypromote degree completion, but students are not morelikely to complete in a STEM degrees.Premed Phenomenon Students who begin premed at institutions are morelikely to complete in STEM, are less likely to completein STEM at selective institutions, high % of premedscauses students to switch from STEM among four yearcompleters—presumably a talented group.
ConclusionSupportive 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
ConclusionIn order to produce 1 million more STEMdegrees, we have to address diversity andequity in attainments and improve access toSTEM careers.Call for evidence-based teaching practices inSTEM.New initiatives by AAU and APLU indicategreat interest in ―demonstration campuses‖ thatcan make transformations to increaseproductivity of STEM degrees.
