The Influence of Microaffirmations on Undergraduate Persistence in Science Career Pathways

The present studies aimed to advance the measurement and understanding of microaffirmation kindness cues and assessed how they related to historically underrepresented (HU) and historically overrepresented (HO) undergraduate student persistence in science-related career pathways. Study 1 developed and tested the dimensionality of a new Microaffirmations Scale. Study 2 confirmed the two-factor structure of the Microaffirmations Scale and demonstrated that the scale possessed measurement invariance across HU and HO students. Further, the scale was administered as part of a longitudinal design spanning 9 months, with results showing that students’ reported microaffirmations did not directly predict higher intentions to persist in science-related career pathways 9 months later. However, scientific self-efficacy and identity, measures of student integration into the science community, mediated this relationship. Overall, our results demonstrated that microaffirmations can be measured in an academic context and that these experiences have predictive value when they increase students’ integration into their science communities, ultimately resulting in greater intentions to persist 9 months later. Researchers and practitioners can use the Microaffirmations Scale for future investigations to increase understanding of the positive contextual factors that can ultimately help reduce persistence gaps in science, technology, engineering, and mathematics degree attainment.

Evaluating Psychosocial Mechanisms Underlying STEM Persistence in Undergraduates: Scalability and Longitudinal Analysis of Three Cohorts from a Six-Day Pre–College Engagement STEM Academy Program

In a previous report, we validated that a cohort of first-year undergraduates who participated in a weeklong pre–college engagement STEM Academy (SA) program were retained in science, technology, engineering, and mathematics (STEM) at a higher rate than a matched comparison group (MCG). In addition, SA students yielded increases in science identity and sense of belonging to STEM and to the university. Here, we report the ability to scale the size of the SA program to accommodate more students and replicate the previous findings with two additional cohorts. Longitudinal analysis of the 2015 and 2016 program cohorts demonstrate that both groups were retained to STEM disciplines and the university at higher rates than a MCG. To assess what underlying psychological mechanisms lead to increases in science identity and university belonging, we tested three exploratory models. These models indicate that positive changes in university and STEM belonging indirectly predict an increase in science identity. Further, positive changes in perceived family support indirectly predict increases in university belonging. Thus, through the evaluation of three different cohorts, we found robust evidence that the SA program increases sense of belonging and science identity, and these attitudinal changes promote undergraduate persistence in STEM.

A Measure of College Student Persistence in the Sciences (PITS)

Curricular changes that promote undergraduate persistence in science, technology, engineering, and mathematics (STEM) disciplines are likely associated with particular student psychological outcomes, and tools are needed that effectively assess these developments. Here, we describe the theoretical basis, psychometric properties, and predictive abilities of the Persistence in the Sciences (PITS) assessment survey designed to measure these in course-based research experiences (CREs). The survey is constructed from existing psychological assessment instruments, incorporating a six-factor structure consisting of project ownership (emotion and content), self-efficacy, science identity, scientific community values, and networking, and is supported by a partial confirmatory factor analysis. The survey has strong internal consistency (Cronbach’s alpha: α = 0.96) and was validated using standard simple and multiple regression analyses. The regression analyses demonstrated that the factors of the PITS survey were significant predictors of the intent to become a research scientist and, as such, potentially valid for the measurement of persistence in the sciences. The PITS survey provides an effective method for measuring the psychological outcomes of undergraduate research experiences relevant to persistence in STEM and offers an approach to the development and validation of more sophisticated assessment tools that recognize the specificities of the type of educational opportunities embedded in a CRE.

A Study of Undergraduate Persistence by Unmet Need and Percentage of Gift Aid

This study examines how undergraduate fall-to-fall persistence is related to unmet financial need and amount of gift aid. Unmet need has been calculated two different ways: (1) total unmet need and (2) unmet need with parental, unsubsidized, and private loans removed. For students who received varying amounts of gift aid, persistence is studied as it relates to the percent of the total aid package that is gift aid. Five years of student persistence and financial aid information are examined.
