In this research-based paper, we explore the relationships among Rice University STEM students’ high school preparation, psychological characteristics, and career aspirations. Although greater high school preparation in STEM coursework predicts higher STEM retention and performance in college [1], objective academic preparation and college performance do not fully explain STEM retention decisions, and the students who leave STEM are often not the lowest performing students [2]. Certain psychosocial experiences may also influence students’ STEM decisions. We explored the predictive validity of 1) a STEM diagnostic exam as an objective measure of high school science and math preparation and 2) self-efficacy as a psychological measure on long-term (three years later) STEM career aspirations and STEM identity of underprepared Rice STEM students. University administrators use diagnostic exam scores (along with other evidence of high school underpreparation) to identify students who might benefit from additional support. Using linear regression to explore the link between diagnostic exam scores and self-efficacy, exam scores predicted self-efficacy a semester after students’ first semester in college; exam scores were also marginally correlated with self-efficacy three years later. Early STEM career aspirations predicted later career aspirations, accounting for 21.3% of the variance of career outcome expectations three years later (β=.462, p=.006). Scores on the math diagnostic exam accounted for an additional 10.1% of the variance in students’ three-year STEM career aspirations (p=.041). Self-efficacy after students’ first semester did not predict future STEM aspirations. Early STEM identity explained 28.8% of the variance in three-year STEM identity (p=.001). Math diagnostic exam scores accounted for only marginal incremental variance after STEM identity, and self-efficacy after students’ first semester did not predict three-year STEM aspirations. Overall, we found that the diagnostic exam provided incremental predictive validity in STEM career aspirations after students’ sixth semester of college, indicating that early STEM preparation has long-lasting ramifications for students’ STEM career intentions. Our next steps include examining whether students’ diagnostic exam scores predict STEM graduation rates and final GPAs for science and math versus engineering majors.

Development and Validation of the STEM Study Strategies Questionnaire for STEM College Students
In this research-based paper, we discuss the development of a measure of Rice University students’ STEM study strategies and then explore the measure’s correlation with several important psychological outcomes in a sample of underprepared first-year STEM students (n=94). STEM attrition remains a pressing concern nationally, particularly for students who took less rigorous STEM courses in high school, a population that disproportionally comprises underrepresented minorities. The authors developed an 11-item measure of STEM-specific study strategies, termed the STEM Study Strategies Questionnaire. We explored STEM-specific identity, self-efficacy, and career aspirations, as well as perceived utility of attaining a STEM degree, using a model based on Eccles and Wigfield’s (2002) expectancy-value framework of achievement. An exploratory factor analysis found a four-factor solution to the newly developed scale: Group Work in STEM, Active STEM Learning, Interactions with STEM Professors, and STEM Exam Familiarity. The authors found significant moderate to strong correlations among all psychological variables, as well as with the Group Work and STEM Exam Familiarity factors. Next steps for this research are to develop further measure items to capture each of the four factors and to conduct confirmatory analyses on different samples of STEM students, both those who are relatively underprepared and appropriately prepared for college STEM coursework.

The current study examines the validity of the RESP diagnostic exam and its predictive validity relative to standardized tests with a sample of students (N = 976) who matriculated into Rice University from 2012 to 2014. The RESP diagnostic exam was related to grades, and we found that the correlation between the RESP diagnostic exam and grades was greater for STEM grades than non-STEM grades. We found that the diagnostic exam accounted for an incremental 9% of variance in STEM grades above SAT performance, but only 1% of incremental variance above SAT in non-STEM grades. Moreover, we found evidence of range restriction for both SAT and RESP diagnostic exam performance for Rice University matriculants, further suggesting the utility of the diagnostic exam is at the lower end of the distribution. In summary, our results suggest that an additional diagnostic exam written by schools to specifically measure STEM preparation for their program can be a useful addition to procedures for selecting students for special experiences such as summer bridge programs.more » « less

Historically Black colleges and universities (HBCUs) are important for diversifying the science technology, engineering, and mathematics (STEM) workforce. This study aims to develop a scale to understand the experiences of HBCU STEM students to spur research on the factors associated with HBCUs’ success with recruiting, retaining, and graduating Black STEM students. Nearly 3,000 undergraduate STEM students across 30 HBCUs participated in this study. The authors conducted exploratory and confirmatory factor analysis to examine the construct validity. The survey had a seven-factor structure with a comparative fit index of 0.9 and high reliability with Cronbach’s alpha ranging from 0.68-0.91. Five factors significantly predicted student outcomes, indicating predictive validity. The resulting survey, HBCU Student STEM Success Survey, provides a reliable and valid measure for HBCU STEM students’ experiences.more » « less

Abstract Background The ability to navigate obstacles and embrace iteration following failure is a hallmark of a scientific disposition and is hypothesized to increase students’ persistence in science, technology, engineering, and mathematics (STEM). However, this ability is often not explicitly explored or addressed by STEM instructors. Recent collective interest brought together STEM instructors, psychologists, and education researchers through the National Science Foundation (NSF) research collaborative Factors affecting Learning, Attitudes, and Mindsets in Education network (FLAMEnet) to investigate intrapersonal elements (e.g., individual differences, affect, motivation) that may influence students’ STEM persistence. One such element is fear of failure (FF), a complex interplay of emotion and cognition occurring when a student believes they may not be able to meet the needs of an achievement context. A validated measure for assessing FF, the Performance Failure Appraisal Inventory (PFAI) exists in the psychological literature. However, this measure was validated in community, athletic, and general undergraduate samples, which may not accurately reflect the motivations, experiences, and diversity of undergraduate STEM students. Given the potential role of FF in STEM student persistence and motivation, we felt it important to determine if this measure accurately assessed FF for STEM undergraduates, and if not, how we could improve upon or adapt it for this purpose. Results Using exploratory and confirmatory factor analysis and cognitive interviews, we re-validated the PFAI with a sample of undergraduates enrolled in STEM courses, primarily introductory biology and chemistry. Results indicate that a modified 15-item four-factor structure is more appropriate for assessing levels of FF in STEM students, particularly among those from groups underrepresented in STEM. Conclusions In addition to presenting an alternate factor structure, our data suggest that using the original form of the PFAI measure may significantly misrepresent levels of FF in the STEM context. This paper details our collaborative validation process and discusses implications of the results for choosing, using, and interpreting psychological assessment tools within STEM undergraduate populations.more » « less

While much has changed in the seven years since the 2016 start of our NSF S-STEM Program, the WVU Academy of Engineering Success (AcES), the goal to increase the number of graduating engineers and contribute to the diversification of the engineering workforce has remained constant [1], [2]. AcES has endeavored to attract, support, and retain through graduation talented, but underprepared (non-calculus-ready) first-time, full-time engineering and computing undergraduate students from underrepresented populations by implementing established, research-based student success and retention strategies. During the seven (7) years of NSF funding, this program has served 71 students and supported 28 students with renewable S-STEM scholarships. Past research used surveys and individual and focus group interviews to measure AcES scholars' feelings of institutional inclusion, engineering self-efficacy and identity, and assessment of their own development of academic and professional success skills [1], [2]. Results supported the Kruger-Dunning Effect, "a cognitive bias in which unskilled people do not recognize their incompetence in specific areas and often overestimate their abilities" [3], [4], [5]. Specifically, students who did not retain to the second year tended to enter college with unrealistic expectations regarding: (1) the time and effort required to succeed in a challenging major and (2) their ability to succeed with little effort. Students tended to underestimate the challenges and overestimate their ability to meet the challenges. [2], [3], [5]. Instead of focusing on those who left the program, this work focuses on AcES scholars who have completed or nearly completed an engineering or computing degree even through the additional complications and challenges presented by the COVID-19 pandemic. From these successful graduates, we hope to learn what elements of the AcES program were the most impactful to and supportive of their journey. The lessons learned are shared to inform other, future engineering education programs.more » « less
