Patching the Pipeline Reducing Educational Disparities in the Sciences Through Minority Training Programs

For more than 40 years, there has been a concerted national effort to promote diversity among the scientific research community. Yet given the persistent national-level disparity in educational achievements of students from various ethnic and racial groups, the efficacy of these programs has come into question. The current study reports results from a longitudinal study of students supported by a national National Institutes of Health–funded minority training program, and a propensity score matched control. Growth curve analyses using Hierarchical Linear Modeling show that students supported by Research Initiative for Science Excellence were more likely to persist in their intentions to pursue a scientific research career. In addition, growth curve analyses indicate that undergraduate research experience, but not having a mentor, predicted student persistence in science.

Using Direct Behavior Rating (DBR) to Screen for School Social Risk A Preliminary Comparison of Methods in a Kindergarten Sample

In this study, preliminary evidence of the potential for Direct Behavior Rating (DBR) in screening assessment of school social behavior is provided through evaluation of the concurrent validity of DBR with a commonly used criterion measure. The teacher-completed form of the Social Skills Rating System (SSRS) was selected as the criterion measure given similarity to DBR in both broad construct of interest and intended use. Classroom teachers completed DBRs of academic engagement and disruptive behavior twice daily, along with fall and spring completion of the SSRS. Overall results support a moderate to strong association between the methods, with stronger correlations in the fall assessment period. In addition, evidence of teacher acceptability for DBR is provided. Along with specific recommendations for future research, implications are discussed regarding selection and interpretation of behavior assessment methods for screening purposes.

Early Engagement in Course-Based Research Increases Graduation Rates and Completion of Science, Engineering, and Mathematics Degrees

This study shows that participation in course-based undergraduate research experiences (CUREs) improves students’ likelihood of graduating with a STEM degree and graduating within 6 years. These results support offering CUREs in place of standard lab courses as an effective strategy for producing additional college graduates with STEM degrees.

Diversifying Science Intervention Programs Moderate the Effect of Stereotype Threat on Motivation and Career Choice

Stereotypes influence academic interests, performance, and ultimately career goals. The long-standing National Institutes of Health Research Initiative for Scientific Enhancement (RISE) training program has been shown to be effective at retaining underrepresented minorities in science. We argue that programs such as RISE may alter the experience and impact of stereotype threat on academic achievement goals and future engagement in a scientific career. We report analyses of a national sample comparing RISE students with a propensity score-matched control group over a 6-year period. Mediation analyses revealed that while RISE program membership did not buffer students from stereotype threat, it changed students’ downstream responses and ultimately their academic outcomes. Nonprogram students were less likely than RISE students to persist in the sciences, partially because feelings of stereotype threat diminished their adoption of mastery goals. We discuss how these findings inform stereotype threat and goal orientation theories and provide insight into the success of intervention programs.

Undergraduate Research Experiences Broaden Diversity in the Scientific Workforce

New data highlight the importance of undergraduate research experiences (UREs) for keeping underrepresented science students on the pathway to a scientific career. We used a large-scale, 10-year, longitudinal, multi-institutional, propensity-score-matched research design to compare the academic performance and persistence in science of students who participated in URE(s) with those of similar students who had no research experience. Our results showed that students who completed 10 or more hours of cocurricular, faculty-mentored research per week across two or more academic semesters or summers were significantly more likely to graduate with a science-related bachelor’s degree, to be accepted into a science-related graduate training program, and to be training for or working in the scientific workforce 6 years after graduation. Importantly, the findings show that just having a URE was not enough to influence persistence in science; it required a commitment of 10 or more hours per week over two or more semesters of faculty-mentored research.

Protégé Perceptions of High Mentorship Quality Depend on Shared Values More Than on Demographic Match

Mentoring, particularly same-gender and same-race mentoring, is increasingly seen as a powerful method to attract and retain more women and racial minorities into science, technology, engineering, and mathematics (STEM) education and careers. This study examines elements of a mentoring dyad relationship (i.e., demographic and perceived similarity) that influence the quality of mentorship, as well as the effect of mentorship on STEM career commitment. A national sample of African American undergraduates majoring in STEM disciplines were surveyed in their senior year. Overall, perceived similarity, rather than demographic similarity, was the most important factor associated with protégé perceptions of high quality mentorship and high quality mentoring was in turn associated with higher commitment to STEM careers. We discuss the implications for mentoring underrepresented students and broadening participation in STEM.ABSTRACT Mentoring, particularly same-gender and same-race mentoring, is increasingly seen as a powerful method to attract and retain more women and racial minorities into science, technology, engineering, and mathematics (STEM) education and careers.

A Longitudinal Study of How Quality Mentorship and Research Experience Integrate Underrepresented Minorities into STEM Careers

This longitudinal study examines how undergraduate research experience and quality mentorship experiences in college predict the growth of scientific efficacy, identity, and values. Results also show how growth trajectories predict students who stay in STEM, pursue medical/health degrees, or leave STEM careers 4 years after graduation.

Student Integration into STEM Careers and Culture: A Longitudinal Examination of Summer Faculty Mentors and Project Ownership

It is widely recognized that the United States needs to attract and retain more people in science, technology, engineering, and mathematics (STEM) careers. Intensive undergraduate research experiences (UREs) are one of the few strategies shown to improve longitudinal student interest and persistence in STEM-related career pathways; however, less is known about the underlying process linking activities to positive outcomes. The tripartite integration model of social influences (TIMSI) provides a framework for understanding the social influence processes by which students integrate into STEM careers and culture. The current study used a longitudinal design and latent growth curve modeling to examine and predict the development of scientific research career persistence intentions over the course of an intensive summer URE. The latent growth curve analysis showed that student persistence intentions declined and rebounded over the course of the summer. Furthermore, the positive impact of faculty mentor role modeling on growth trajectories was mediated through internalization of science community values. In addition, project ownership was found to buffer students from the typical trend of declining and rebounding persistence intentions. The TIMSI framework illuminates the contextual features and underlying psychological processes that link UREs to student integration into STEM careers and culture.

Promoting professional identity, motivation, and persistence: Benefits of an informal mentoring program for female undergraduate students

Women are underrepresented in a number of science, technology, engineering, and mathematics (STEM) disciplines. Limited diversity in the development of the STEM workforce has negative implications for scientific innovation, creativity, and social relevance. The current study reports the first-year results of the PROmoting Geoscience Research, Education, and SuccesS (PROGRESS) program, a novel theory-driven informal mentoring program aimed at supporting first- and second-year female STEM majors. Using a prospective, longitudinal, multi-site (i.e., 7 universities in Colorado/Wyoming Front Range & Carolinas), propensity score matched design, we compare mentoring and persistence outcomes for women in and out of PROGRESS (N = 116). Women in PROGRESS attended an off-site weekend workshop and gained access to a network of volunteer female scientific mentors from on- and off-campus (i.e., university faculty, graduate students, and outside scientific professionals). The results indicate that women in PROGRESS had larger networks of developmental mentoring relationships and were more likely to be mentored by faculty members and peers than matched controls. Mentoring support from a faculty member benefited early-undergraduate women by strengthening their scientific identity and their interest in earth and environmental science career pathways. Further, support from a faculty mentor had a positive indirect impact on women’s scientific persistence intentions, through strengthened scientific identity development. These results imply that first- and second- year undergraduate women’s mentoring support networks can be enhanced through provision of protégé training and access to more senior women in the sciences willing to provide mentoring support.
