1. Impacts Resulting from a Large-Scale First-Year Engineering and Computer Science Program on Students’ Successful Persistence Toward Degree Completion

   Ragusa, Gisele; Allen, Emily L.; Menezes, Gustavo B. (June 2020, ASEE Annual Conference Proceedings 2020)

   There is a critical need for more students with engineering and computer science majors to enter into, persist in, and graduate from four-year postsecondary institutions. Increasing the diversity of the workforce by inclusive practices in engineering and science is also a profound identified need. According to national statistics, the largest groups of underrepresented minority students in engineering and science attend U.S. public higher education institutions. Most often, a large proportion of these students come to colleges and universities with unique challenges and needs, and are more likely to be first in their family to attend college. In response to these needs, engineering education researchers and practitioners have developed, implemented and assessed interventions to provide support and help students succeed in college, particularly in their first year. These interventions typically target relatively small cohorts of students and can be managed by a small number of faculty and staff. In this paper, we report on “work in progress” research in a large-scale, first-year engineering and computer science intervention program at a public, comprehensive university using multivariate comparative statistical approaches. Large-scale intervention programs are especially relevant to minority serving institutions that prepare growing numbers of students who are first in their family to attend college and who are also under-resourced, financially. These students most often encounter academic difficulties and come to higher education with challenging experiences and backgrounds. Our studied first-year intervention program, first piloted in 2015, is now in its 5th year of implementation. Its intervention components include: (a) first-year block schedules, (b) project-based introductory engineering and computer science courses, (c) an introduction to mechanics course, which provides students with the foundation needed to succeed in a traditional physics sequence, and (d) peer-led supplemental instruction workshops for calculus, physics and chemistry courses. This intervention study responds to three research questions: (1) What role does the first-year intervention’s components play in students’ persistence in engineering and computer science majors across undergraduate program years? (2) What role do particular pedagogical and cocurricular support structures play in students’ successes? And (3) What role do various student socio-demographic and experiential factors play in the effectiveness of first-year interventions? To address these research questions and therefore determine the formative impact of the firstyear engineering and computer science program on which we are conducting research, we have collected diverse student data including grade point averages, concept inventory scores, and data from a multi-dimensional questionnaire that measures students’ use of support practices across their four to five years in their degree program, and diverse background information necessary to determine the impact of such factors on students’ persistence to degree. Background data includes students’ experiences prior to enrolling in college, their socio-demographic characteristics, and their college social capital throughout their higher education experience. For this research, we compared students who were enrolled in the first-year intervention program to those who were not enrolled in the first-year intervention. We have engaged in cross-sectional 2 data collection from students’ freshman through senior years and employed multivariate statistical analytical techniques on the collected student data. Results of these analyses were interesting and diverse. Generally, in terms of backgrounds, our research indicates that students’ parental education is positively related to their success in engineering and computer science across program years. Likewise, longitudinally (across program years), students’ college social capital predicted their academic success and persistence to degree. With regard to the study’s comparative research of the first-year intervention, our results indicate that students who were enrolled in the first-year intervention program as freshmen continued to use more support practices to assist them in academic success across their degree matriculation compared to students who were not in the first-year program. This suggests that the students continued to recognize the value of such supports as a consequence of having supports required as first-year students. In terms of students’ understanding of scientific or engineering-focused concepts, we found significant impact resulting from student support practices that were academically focused. We also found that enrolling in the first-year intervention was a significant predictor of the time that students spent preparing for classes and ultimately their grade point average, especially in STEM subjects across students’ years in college. In summary, we found that the studied first-year intervention program has longitudinal, positive impacts on students’ success as they navigate through their undergraduate experiences toward engineering and computer science degrees.

2. Board 207: ACCESS in STEM: An S-STEM Project Supporting Economically Disadvantaged STEM-Interested Students in Their First Two Years

   https://doi.org/10.18260/1-2--42618  

   Cline, Erica; Abraham, Menaka; Alaei, Sarah; Dillon, Heather; Dinglasan-Panlilio, Joyce; Heller, Jutta; Kmail, Zaher; Lee, Seung-Jin; Ma, Eva; Nahmani, Marc; et al (June 2023, ASEE Conferences)

   Achieving Change in our Communities for Equity and Student Success (ACCESS) in STEM at the University of Washington Tacoma started as a Track 1 S-STEM program in 2018 and has supported 69 students to date. This year we received Track 2 funding and welcomed our fifth cohort to campus, with funding to support ~32 additional students through 2026. University of Washington Tacoma is an Asian American and Native American Pacific Islander-serving institution (AANAPISI), and we serve a high proportion of racial minority and first generation college students. Our ACCESS scholars are pursuing bachelor’s degrees in Mathematics, Environmental Science, Biomedical Sciences, Information Technology, Computer Science and Systems, Computer Engineering and Systems, Electrical Engineering, Mechanical Engineering, and Civil Engineering, with Computer Science and Engineering representing over 60% of ACCESS scholars to date. First-time college students and first-year transfer students receive full scholarships for their first two years, and partial scholarships for their third and fourth years. The project includes an optional Early Fall Math course to enhance entry into STEM majors, and participants are able to engage in a Research Experience or project-based Introduction to Engineering course in their first year. Coupled with individual faculty mentoring and an on-campus STEM living learning community, the quarterly Success in STEM seminar course helps scholars form a cohesive community through group mentoring, as well as develop a sense of belonging, identity, and empowerment to transform the culture of STEM. This program is distinguished by its focus on pre-STEM majors in their first and second years on campus, and includes mentor training for ~30-40 faculty in teaching and mentoring diverse student populations, thus impacting all students in our majors. Our goal was to evaluate the effectiveness of a program that focuses on the first two years of college and provides financial support, courses to introduce students to research and project-based engineering, and intensive mentoring in increasing retention and academic success for Computer Science and Engineering (CS+E) students, and whether this program helps to close equity gaps for CS+E students who are low socioeconomic status (SES), underrepresented minorities (URMs), female, and/or first generation in college (First Gen) students. We compared our student scholars to a comparison group of students who met eligibility requirements but did not participate in the program. Program scholars had higher first and second year retention, and had significantly higher GPAs. The pandemic resulted in significant social, emotional, and economic stresses for our program scholars, which may have heightened the impact of the ACCESS in STEM program.

3. First-Year Experience (FYrE@ECST): Pre-Physics Course (WIP)

   Li, Ni; Menezes, Gustavo B.; Allen, Emily L; Nerenberg, Paul (April 2018, Proceedings 2018 CONECD Conference)

   The College of Engineering, Computer Science, and Technology (ECST) at California State University, Los Angles, an Hispanic Serving Institution (HSI) with over 60% Hispanic students, is committed to improving graduation rates through the Grad initiative 2025 (the California State University’s initiative to increase graduation rates for all CSU students while eliminating achievement gaps). The majority of our students are under-represented minorities, low-income, Pell-eligible and first generation. Currently, one quarter of the students leaving the major before the second year. Many that “survive” the first two years of math and science do not develop the knowledge and the skills that are needed to succeed in upper division engineering courses, leading to more students unable to finish their engineering majors. Three years ago, we launched a pilot program for the First-Year Experience at ECST (FYrE@ECST) for incoming freshmen. The program focuses on providing academic support for math and physics courses while introducing students to the college community, and comprises a summer bridge program, a hands-on introductory course, cohorted math and science sections, and staff and faculty mentoring. Academic support is provided through peer-led supplemental instruction (SI) workshops. The workshops have led to a significant improvement in student performance in Math, but have had no significant impact in the student performance in physics. Our hypothesis is that students, in addition to having limited understanding of calculus, struggle to understand the fundamental principles of physics and thus cannot apply their knowledge of math to theories in physics to solve problems. This work-in-progress paper describes an inquiry-based hands-on pre-physics course for first-year students as part of the FYrE@ECST program. The course is intended to prepare students for the calculus-based mechanics course in physics and covers about half of the competencies of a classical mechanics course, with focuses on the fundamental concepts of mechanics (i.e. Newton’s Laws, Types of forces, vectors, free-body diagrams, position, velocity and acceleration). Equations are only introduced in the second half of the semester, while the first half is directed to help students develop a deep understanding of these fundamental concepts. During classes, students run simple experiments, watch segments of movies and cartoons and are asked questions (written and orally) which can guide them to think intuitively and critically. A think-pair-share mode of instruction is implemented to promote inquiry and discussion. Students work in groups of five to discuss and solve problems, carry out experiments to better understand processes and systems, and share what they learned with the whole class. The paper presents preliminary results on student achievement.

4. Board 317: Institutional Practices to Close the Equity Gap

   https://doi.org/10.18260/1-2--46896  

   Cline, EC; Dillon, Heather; Sesko, Amanda; Nahmani, Marc; Kmail, Zaher; Dinglasan-Panlilio, Joyce; Lee, Seung-Jin; Cilli-Turner, Emily; Björling, Elin (June 2024, ASEE Conferences)

   The S-STEM supported program “Achieving Change in our Communities for Equity and Student Success” (ACCESS) in STEM started at the University of Washington Tacoma in 2018 and has supported 108 students over 6 cohorts. University of Washington Tacoma has been designated an Asian American and Native American Pacific Islander-serving institution (AANAPISI) due to our high proportion of racial minority and first generation college students. The program is multidisciplinary across STEM majors including Mathematics, Environmental Science, Biomedical Sciences, Information Technology, Computer Science and Systems, Computer Engineering and Systems, Electrical Engineering, Mechanical Engineering, and Civil Engineering, with Computer Science, IT and Engineering representing 65% of ACCESS scholars to date. Program scholars receive full scholarships for their first two years, and partial scholarships for their third and fourth years. We provide a summer bridge precalculus or research experience course, and project-based Introduction to Engineering or Introduction to Research courses in students’ first year. Individual faculty mentoring, an on-campus STEM living learning community,and quarterly Success in STEM seminar courses help scholars form a cohesive community through group mentoring, to promote a sense of belonging, identity, and empowerment in the STEM community. Our S-STEM program is distinctive in focusing on pre-STEM majors in their first and second years on campus to facilitate the entry into STEM majors, and we provide mentor training for ~30-40 faculty in teaching and mentoring diverse student populations, thus impacting all students in our majors. Our goal was to evaluate how retention and academic success of our program scholars was impacted by the program, and whether this program helps to close equity gaps for students who identify as low socioeconomic status, underrepresented minorities, women or non-binary, or first generation in college . We also evaluated the impact of the program for students before, during, and after the Covid-19 pandemic. We compared our program scholars to a comparison group of students who met eligibility requirements but did not participate in the program. Overall, program scholars had higher first and second year retention, and significantly higher GPAs, particularly for individuals belonging to groups that are historically underrepresented in STEM. Retention was markedly higher for program scholars during the pandemic, suggesting that the program may have been particularly impactful for students as they endured the emotional and financial stresses of the pandemic.

5. Improving First-Year Engineering Student Success with Targeted Financial Assistance, Supplemental Instruction, and Cohort Team Building

   https://doi.org/10.18260/1-2--47591  

   Cruse, Krystal; Boyet, Carl; Palmer, James (June 2024, ASEE Conferences)

   This complete research paper assesses the first-year implementation of an NSF-funded S-STEM effort, the SUCCESS Scholars Program (SSP), established in the Fall of 2022 at Louisiana Tech University. Louisiana Tech University is a Carnegie High Research Activity University that has approximately 20% of its 7500 undergraduates as engineering majors, is geographically distanced from large metropolitan areas but draws its student population both statewide and regionally and operates on the quarter calendar. Louisiana Tech University merged the math, chemistry, and physics programs with the engineering, technology, and computer science programs into a single college in 1995 and created an integrated freshman engineering curriculum in 1998. Louisiana Tech University has a long history of educational innovations in engineering education, with a hands-on project-based approach implemented in 2004 and four other NSF-funded programs to increase student success in engineering since 2007. The SSP builds on these prior efforts by providing financial, academic, personal, and professional support to engineering students starting in their first year of college through four years of academic study. The first cohort of twenty-four students was selected through an application process after learning about the program at orientation. The SSP team focused heavily in the first year on academic support and community building while also providing each student a financial scholarship of up to $10,000 depending on unmet financial need. Throughout the first year, students in the SSP attended a three-day-a-week first-year engineering course instead of the typical two-day-a-week course. This provided additional access to the lab equipment, contact hours with their instructor, practice problems, and helped foster community among the cohort. Additional academic support was provided through supplemental instruction sessions strategically designed to provide support in both their engineering and mathematics courses. These sessions were led by upper-level peer mentors. Students were connected with faculty mentors in their discipline through lunches that the SSP faculty team provided each week. These lunches helped reduce food insecurity while also providing an inviting atmosphere for interaction between peers and faculty. Lunches also offered an opportunity to have career discussions and bring in professional development speakers like student organization leaders and graduate students. At the start of the first quarter of their sophomore year, nineteen students were either still on track or just one quarter behind in their engineering curriculum. This record will be compared with the approximately 420 students who either were eligible or did not take part in this program. Historical data will be reviewed to determine how predictive these initial markers are toward completion of the degree.
