SignificanceThe Science Education Alliance–Phage Hunters Advancing Genomics and Evolutionary Science program is an inclusive Research Education Community with centralized programmatic and scientific support, in which broad student engagement in authentic science is linked to increased accessibility to research experiences for students; increased persistence of these students in science, technology, engineering, and mathematics; and increased scientific productivity for students and faculty alike.

In diverse classrooms, stereotypes are often “in the air,” which can interfere with learning and performance among stigmatized students. Two studies designed to foster equity in college science classrooms ( Ns = 1,215 and 607) tested an intervention to establish social norms that make stereotypes irrelevant in the classroom. At the beginning of the term, classrooms assigned to an ecological-belonging intervention engaged in discussion with peers around the message that social and academic adversity is normative and that students generally overcome such adversity. Compared with business-as-usual controls, intervention students had higher attendance, course grades, and 1-year college persistence. The intervention was especially impactful among historically underperforming students, as it improved course grades for ethnic minorities in introductory biology and for women in introductory physics. Regardless of demographics, attendance in the intervention classroom predicted higher cumulative grade point averages 2 to 4 years later. The results illustrate the viability of an ecological approach to fostering equity and unlocking student potential.

Identifying as a “science person” is predictive of science success, but the mechanisms involved are not well-understood. We hypothesized that science identity predicts success because it fosters a sense of belonging in science classrooms. Thus, science identity should be particularly important for first-generation and racial-minority students, who may harbor doubts about belonging in science. Two field studies in college Introductory Biology classes ( Ns = 1368, 639) supported these hypotheses. A strong science identity predicted higher grades, particularly for minority students. Also consistent with hypotheses, Study 2 found that self-reported belonging in college mediated the relationship between science identity and performance. Furthermore, a social belonging manipulation eliminated the relationship between science identity and performance among minority students. These results support the idea that a strong science identity is particularly beneficial for minority students because it bolsters belonging in science courses. Practical and theoretical implications are discussed.

Accordingly, skills gaps have been the focus of considerable research and policy. Despite this attention, economic disparities in children's outcomes have grown over the past fifty years, even as racial-ethnic disparities have declined (Reardon 2011). Wealth and Child Development: Differences in Associations by Family Income and Developmental StageportI a mIller, ta m a r a podv ysotsk a , l aur a beta ncur, a nd elIz a beth votruba-dr z a lWealth inequality is at a historic high in the United States. Yet little is known about the implications of wealth on children's development because research has focused mainly on the role of wealth in shaping outcomes in adulthood. Using data from the National Longitudinal Survey of Youth (N = 8,095), we examine how family wealth relates to achievement and behavior problems during early childhood, middle childhood, and adolescence. Further, we explore whether links between wealth and children's development vary by level of income and income volatility. Results show that wealth, controlling for income level and volatility, is uniquely related to both academic and behavioral development in early childhood, middle childhood, and adolescence. Moreover, evidence suggests that wealth plays a buffering role when it comes to protecting children's development from the deleterious effects of low family income, especially as children grow older.

Past research has examined parental support for math during early childhood using parent-report surveys and observational measures of math talk. However, since most studies only present findings from one of these methods, the construct (parental support for early math) and the method are inextricably linked, and we know little about whether these methods provide similar or unique information about children’s exposure to math concepts. This study directly addresses the mono-operation bias operating in past research by collecting and comparing multiple measures of support for number and spatial skills, including math talk during semi-structured observations of parent–child interactions, parent reports on a home math activities questionnaire, and time diaries. Findings from 128 parents of 4-year-old children reveal substantial within-measure variability across all three data sources in the frequency of number and spatial activities and the type and content of parent talk about number and spatial concepts. Convergence in parental math support measures was evident among parent reports from the questionnaire and time diaries, such that scale composites about monthly number activities were related to number activities on the previous work day, and monthly spatial activities were correlated with spatial activities the prior non-work days. However, few parent report measures from the survey or time diary were significantly correlated with observed quantity or type of math talk in the semi-structured observations. Future research implications of these findings are discussed.
