Background & Program Description: The link between student engagement and retention is well-established in the education literature. As a result, many colleges have developed first-year experience programs to engage students in early technical work and to promote community-building. However, many of these student success programs require participation in extracurricular activities, which require time outside of class. Yet time for extracurricular activities is a luxury that many students of low socioeconomic status (SES) cannot afford due to family or work obligations.
The Scholarships in STEM (S-STEM) program, funded by the National Science Foundation, provides crucial financial support to high-achieving low-SES STEM students. The S-STEM scholarships give students the option to work less or not at all. The intended result is that students regain the time afforded to their more privileged peers, thereby also giving them the opportunity to more effectively engage with their institution, studies, and peers.
The Endeavour Program is a two-year program that incorporates the S-STEM financial support into a multi-faceted and multi-college program in STEM designed to increase the level of student engagement in school. The scholars, who are recruited from three colleges, take classes together, work on hands-on team projects, attend professional and personal development events, participate in outreach events, and conduct research with faculty mentors. Over the course of the two-year program, four dimensions of student engagement (academic, behavioral, cognitive, and affective) are tracked to determine the appropriateness of using these engagement levels as predictors of success.
Results: Two cohorts of 20 students were recruited in the fall of 2017 and in the fall of 2018. The first cohort completed the two-year program in the spring of 2020, and the second cohort began the second year of the program in the fall of 2020. No third cohort was recruited in 2020 due the Covid19 pandemic. The third and fourth cohorts will now enter the program in the fall of 2021 and the fall of 2022 respectively.
Overall, the results of the Endeavour Program have been positive. The final retention outcome for the first cohort (the only cohort to complete the program thus far) was 85% (17/20). Retention for the second cohort is currently at 100% (20/20). Initial results show that the S-STEM scholars are performing academically as well as their peers who do not share the same risk factors. In addition, the number of completed hours is also on par with their peers. However, the most significant gains were observed in the qualitative data. Students expressed fears and anxieties about the high school to college transition and reported that the guidance provided and the community formed through the Endeavour Program alleviated many of those negative emotions.
The full paper shows student engagement data obtained over time for the first and second cohorts as well as lessons learned and directions for future work. Also, examples of advising charts created in an engagement data dashboard show how the quantitative engagement data has been compiled and organized to show early warning signs for current and future cohorts.

Mechanisms, Models, and Explanations: Analyzing the Mechanistic Paths Students Take to Reach a Product for Familiar and Unfamiliar Organic Reactions
This study is a follow up to two earlier studies characterizing student real-time use of mechanistic arrows. In these previous studies, students were asked to predict a product by drawing a curved arrow mechanism using an interface that allowed recording and replay of student actions. In the present study two different student cohorts responded to the same tasks as the original studies: a cohort who were enrolled in a traditional organic course, and a cohort who were part of a transformed organic course (Organic Chemistry, Life, the Universe and Everything, OCLUE). Both cohorts improved in their ability to predict an appropriate product over the two semesters, and we found little meaningful difference in the ability of students from either cohort to predict the outcome of a familiar reaction. However, students in the OCLUE cohort were more likely to draw mechanistic arrows than the students from the traditional course. In contrast, when the task involved predicting the product of an unfamiliar reaction, OCLUE students were over three times more likely to draw mechanistically reasonable steps and produce a plausible product than students from the traditional cohort. We propose that the differences between the two cohorts emerge from the following: (1) explicit attempts in the OCLUE course to link drawing reactions mechanisms using the electron pushing formalism to the scientific practice of constructing explanations. It is our contention that this approach changes the arrow pushing mechanism from a skill to the construction of a model which students can use to predict and explain outcomes; and (2) the numerous opportunities in the OCLUE course to try out ideas without penalty, leading to a willingness to try to determine outcomes in unfamiliar situations.

Building on prior studies that show a sense of belonging and community bolster student success, we developed a pilot program for computer engineering (CpE) and computer science (CS) undergraduates and their families that focused on building a sense of belonging and community supported by co-curricular and socioeconomic scaffolding. As a dually designated Hispanic-Serving Institution (HSI) and Asian American and Native American Pacific Islander-Serving Institution (AANAPISI) – two types of federally designated Minority-Serving Institutions (MSI) – with 55% of our undergraduates being first-generation students, we aimed to demonstrate the importance of these principles for underrepresented and first-generation students. Using a student cohort model (for each incoming group of students) and also providing supports to build community across cohorts as well as including students’ families in their college experiences, our program aimed to increase student satisfaction and academic success. We recruited two cohorts of nine incoming students each across two years, 2019 and 2020; 69% of participants were from underrepresented racial or minority groups and 33% were women. Each participant was awarded an annual scholarship and given co-curricular support including peer and faculty mentoring, a dedicated cohort space for studying and gathering, monthly co-curricular activities, enhanced tutoring, and summer bridge and orientation programs. Students’ families were also included in the orientation and semi-annual meetings. The program has resulted in students exceeding the retention rates of their comparison groups, which were undergraduates majoring in CpE and CS who entered college in the same semester as the cohorts; first- and second-year retention rates for participants were 83% (compared to 72%) and 67% (compared to 57%). The GPAs of participants were 0.35 points higher on average than the comparison group and, most notably, participants completed 50% more credits than their comparison groups, on average. In addition, 9 of the 18 scholars (all of the students who wanted to participate) engaged in summer research or internships. In combination, the cohort building, inclusion of families, financial literacy education and support, and formal and informal peer and faculty mentoring have correlated with increased academic success. The cohorts are finishing their programs in Spring 2023 and Spring 2024, but data up to this point already show increases in GPA, course completion, and retention and graduation rates, with three students having already graduated early, within three and a half years. The findings from this study are now being used to expand the successful parts of the program and inform university initiatives, with the PI serving on campus-wide STEM pipeline committee aiming to recruit, retain, and support more STEM students at the institution.more » « less

Eastern Mennonite University received a 5-year S-STEM award for their STEM Scholars Engaging in Local Problems (SSELP) program. The goal of this place-based, interdisciplinary scholarship program is to increase the number of academically talented, low-income students who graduate in STEM fields and either pursue immediate employment in STEM careers or STEM-related service or continue their STEM education in graduate school. In 2018 and 2019, two cohorts of seven students were recruited to major in biology, chemistry, engineering, computer science, mathematics, or environmental science. A key part of recruitment involved on-campus interviews, during a February Scholarship Day, between STEM faculty and potential scholars. As the yield rate for the event is high (54-66%), the university has continued this practice, funding additional STEM scholarships. In order to retain and graduate the scholars in STEM fields, the SSELP faculty designed and carried out various projects and activities to support the students. The SSELP Scholars participated in a first-year STEM Career Practicum class, a one-credit course that connected students with regional STEM practitioners across a variety of fields. The scholars were supported by peer tutors embedded in STEM classes, and now many are tutors themselves. They participated in collaborative projects where the cohorts worked to identify and solve a problem or need in their community. The SSELP scholars were supported by both faculty and peer mentors. Each scholarship recipient was matched with a faculty mentor in addition to an academic advisor. A faculty mentor was in a related STEM field but typically not teaching the student. Each scholar was matched with a peer mentor (junior or senior) in their intended major of study. In addition, community building activities were implemented to provide a significant framework for interaction within the cohort. To evaluate the progress of the SSELP program, multiple surveys were conducted. HERI/CIRP Freshman Survey was used in the fall of 2018 for the first cohort and 2019 for the second cohort. The survey indicated an upward shift in students’ perception of science and in making collaborative effort towards positive change. Preliminary data on the Science Motivation Questionnaire showed that the SSELP scholars began their university studies with lower averages than their non-SSELP STEM peers in almost every area of science motivation. After over three years of implementation of the NSF-funded STEM Scholars Engaging in Local Problems program, the recruitment effort has grown significantly in STEM fields in the university. Within the two cohorts, the most common majors were environmental science and engineering. While 100% of Cohorts 1 and 2 students were retained into the Fall semester of the second year, two students from Cohort 1 left the program between the third and fourth semesters of their studies. While one student from Cohort 2 had a leave of absence, they have returned to continue their studies. The support system formed among the SSELP scholars and between the scholars and faculty has benefited the students in both their academic achievement as well as their personal growth.more » « less

This study expands on our prior work of the Research Experience for Undergraduates (REU) SITE program to provide data on participant preparation for success in graduate school and their perceptions of the program. In the first two studies from our initial cohort, we summarized that we effectively provided an independent research experience, increased participants perception of preparedness for success in the graduate application process and graduate school and increased their ability to communicate about Biomechanics and Mechanobiology (BMMB)1. In the follow up study we showed that by the end of the program students believed they were better prepared for success in graduate school, two students co-authored publications from their projects, and the majority were enrolled in a graduate program2. Here we share data across our first two cohorts which expands our outcomes associated with graduate school preparation and student perceptions of the REU SITE program. We used our site-licensed online survey tool Qualtrics to administer the surveys for data collection. We used the same pre- and post-survey data to assess changes for both ten student cohorts over the 10-week period. The data were analyzed using a paired t-test from GraphPad Prism 9.3.0 software. This study confirmed the findings from the first two studies while highlighting new information. The new analysis conducted across both cohorts showed participation in the program influenced student interest in applying to graduate school p< 0.05. Additionally, the data show that participants felt more prepared to conduct independent research after participating p<0.05. Of the twenty participants the twelve students who have graduated or will be graduating before summer 2023 are enrolled in a graduate program or have applied for admission. Six of those yet to graduate reported they plan to pursue a graduate degree after completing their BS degree. Additionally, students felt the program prepared them to find and read research articles p<0.01 and participate at a conference p<0.05, skills that will be beneficial for success in a graduate program. Ninety-five percent of the participants indicated the REU SITE met or exceeded their expectations and would recommend the program to others. Similarly, 95% were satisfied with the mentorship of their graduate ambassador and 100% indicated they were satisfied with the mentorship of their faculty. Additionally, we were excited to find that after an adjustment to our program after the first cohort, the second cohort felt prepared to contribute to the field of BMMB p<0.05. This was an objective of the program that was not achieved with the first cohort. Lastly, 85% of participants were from underrepresented minority (URM) backgrounds and 70% were female. Thus, the enrollment of our participants in graduate programs continues to enhance diversity in engineering and the field of BMMB. Going forward we will continue to track the progress of participants and the careers they choose after completion of their graduate degrees. We will also continue to use student feedback to improve the experience for participants.more » « less

The STEM Excellence through Engagement in Collaboration, Research, and Scholarship (SEECRS) project at Whatcom Community College is a five-year program aiming to support academically talented students with demonstrated financial need in biology, chemistry, geology, computer science, engineering, and physics. This project is funded by an NSF S-STEM (Scholarships in Science, Technology, Engineering, and Mathematics) grant awarded in January 2017. Through an inclusive and long-range effort, the college identified a strong need for financial and comprehensive supports for STEM students. This project will offer financial, academic, and professional support to three two-year cohorts of students. The SEECRS project aims to utilize a STEM-specific guided pathways approach to strengthen recruitment, retention, and matriculation of STEM students at the community college level. Scholarship recipients will be supported through participation in the SEECRS Scholars Academy, a multi-pronged approach to student support combining elements of community building, faculty mentorship, targeted advising activities, authentic science practice, and social activities. Students are introduced to disciplines of interest through opportunities to engage in course-based undergraduate research experiences (CUREs) in Biology, Chemistry and Engineering courses, funded summer research opportunities, and seminars presented by STEM professionals. Communities of practice will be nurtured through the introduction of cohort building and faculty mentorship. Cohort development starts with a required two-credit course for all scholars that emphasizes STEM identity development, specifically focusing on identifying and coping with the ways non-dominant individuals (racial/ethnic minorities, non-male gender, lower socioeconomic status, first-generation, 2-year community college vs. 4-year institutions) are made to feel as outsiders in STEM. Each SEECRS scholar is paired with a faculty mentor who engages in ongoing mentor training. The project evaluation will determine the efficacy of the project activities in achieving their intended outcomes. Specifically, we will collect data to answer the research question: To what extent can a guided pathways approach provide a coordinated and supported STEM experience at Whatcom Community College that: (1) increases student success, and (2) positively shifts students’ STEM self-identity? The evaluation will employ a quasi-experimental research design, specifically a pretest-posttest design with a matched comparison group. Our first cohort of 14 students was selected over two application rounds (winter and summer 2017). We awarded ten full scholarships and four half-scholarships based on financial need data. Cohort demographics of note compared to institutional percentages are: females (64% vs. 57%), Hispanic (14% vs. 17%), African American (7% vs. 2%), white (79% vs. 66%), first generation college bound (43% vs. 37%). The cohort is comprised of six students interested in engineering, six in biology, and one each in geology and environmental sciences. With increased communication between the project team, our Financial Aid office, Entry and Advising, high school outreach, and the Title III grant-funded Achieve, Inspire, Motivate (AIM) Program, as well as a longer advertising time, we anticipate significantly enhancing our applicant pool for the next cohort. The results and lessons learned from our first year of implementation will be presented.more » « less
