STEM graduation rates, cumulative GPAs, and final GPA distributions of years 2016 to 2019 graduates were evaluated for students who participated in Rice University’s STEM intervention (the Rice Emerging Scholars Program, or RESP, which is partly funded through an NSF SSTEM grant), which begins with a pre-freshman STEM summer bridge program. RESP participants (n=89) and a comparison category of students (n=81) were identified as being underprepared for STEM coursework. Outcomes from the rest of the graduating classes were also assessed (i.e., non-comparison, non-RESP students). Incoming high school AP and IB credits were a moderate predictor of cumulative graduation GPA. After controlling for test credits, student status predicted cumulative graduation GPA, with higher GPAs in the noncomparison, non-RESP condition. Seventy-two RESP students graduated with a STEM major (81% STEM retention) compared with 62% of comparison students and 87% of non-comparison, non-RESP students. A chi-square test found a significant difference in favor of higher STEM retention among RESP students than the comparison students. Of RESP STEM graduates, 94% graduated with at least a B- GPA, compared with 86% of the comparison students, and 97% of the non-comparison, non-RESP students. A chi-square test approached significance in favor of more B- and above GPAs among RESP students than the comparison students. Overall, we found that high school preparation predicted STEM students’ graduation GPAs. Further, although RESP participation did not predict the cumulative GPAs of STEM majors, the program may: 1) improve STEM degree persistence and 2) ensure that more of the program’s STEM graduates achieve at least a B- cumulative graduation GPA. The number of RESP and comparison students is relatively small, yet these findings nevertheless offer preliminary evidence that the intervention may be effective at improving STEM outcomes for students who would otherwise struggle the most with their coursework. As more students graduate from the university, we will be able to make stronger conclusions about the effectiveness of RESP in improving outcomes of underprepared STEM students.

STEM Bridge Program Participation Predicts First- and Second-Semester Math Performance
To combat math underperformance among incoming STEM majors, Rice University designed a summer bridge program with National Science Foundation (NSF) S-STEM funding that included an intensive calculus course. Students invited to participate in the program were identified as being underprepared for STEM classes based on their standardized test scores, high school STEM coursework, and socioeconomic status. One of the program’s goals is to improve students’ preparation for the advanced math courses required for all STEM majors at Rice. The bridge program is designed to teach the material that has historically been most challenging for underprepared students, meaning the math content covered primarily second-semester calculus topics. We explored the impact of bridge program participation on math performance in first and second-semester math. First, we examined group differences in math preparation. Though program administrators attempt to create equivalent bridge and comparison groups, the bridge program is optional, meaning group assignment is not completely random. Bridge students were less prepared than comparison students on number of high school calculus AP (or equivalent) credits received. We analyzed group differences in final class grades from 2012-2017 among the comparison group, the bridge group, and the rest of the class (i.e. non-comparison and nonbridge), standardizing grades using Z-scores. Planned contrasts found that bridge students performed slightly better than, but not significantly different from, comparison students in first semester math. Conversely, planned contrasts found that the bridge group significantly outperformed the comparison group in second-semester math. These results suggest that bridge program exposure to calculus may improve performance relative to a comparison group, which is especially noteworthy because bridge students are the least math-prepared STEM students entering the university. Future research will analyze outcomes in more advanced math classes. We will use these findings to refine the bridge program’s approach to teaching students how to succeed at collegiate-level math classes and, ultimately, as STEM majors at Rice.

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.more » « less

This NSF S-STEM Grantee poster examines the results of Rice University's summer science, technology, engineering, and mathematics (STEM) bridge program, the Rice Emerging Scholars Program (RESP), on participants' introductory chemistry grades in a quasi-experimental design that compared performance of participants in RESP, a control group with similar preparation as RESP participants, and the remaining students in the class. The outcome of interest was first and second-semester chemistry exam performance. The researchers also examined performance on first-semester exam items that directly tested concepts taught in RESP versus concepts that were not taught during the program, as well as class grade distribution by group for both first and second-semester chemistry. Results showed that engaging in RESP enhanced performance on items that directly assessed content taught in the program but did not significantly improve performance on items not taught in RESP. However, the proportion of students in RESP earning As and Bs was no different from other students in the class during the first semester. Although not all results were significant, trends in the data point to the promise of RESP. Implications for near and far learning transfer as a result of program participation are discussed.more » « less

null (Ed.)This Complete Research paper will describe the implementation of an introductory course (ENGR194) for first semester engineering students. The course is meant to improve retention and academic success of engineering first-year students in the College of Engineering at the University of Illinois at Chicago. The implementation of this course is part of an ongoing National Science Foundation (NSF) Scholarships in Science, Technology, Engineering, and Math (S-STEM) project. This paper reports on the impact of combinatorial enrollment in ENGR194 and a previously described two-week Summer Bridge Program (SBP) offered only for entering S-STEM scholars before their first semester. To measure the impact of this course on student retention and academic success, various evaluation metrics are compared for three separate Comparison Groups (C-Groups) of students. The results show that the ENGR194 course had a significant positive impact on the first-year retention rate. The results also revealed that students who participated in both ENGR194 and SBP (C-Group 1) made changes to their declared majors earlier than students who had only taken ENGR 123 or neither of the courses (C-Groups 2 and 3 respectively). Furthermore, students in C-Group 1 received better grades in math and science than their peers, and students in C-Groups 1 and 2 had significantly higher GPAs than their peers in C-Group 3.more » « less

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
