   Promoting equitable undergraduate engineering education is an overarching concern at many minority-serving institutions (MSI). In addition, historical analysis of student performance in lower-division math and engineering courses at one of the largest MSI revealed an achievement gap in performance between the underrepresented minority students and other students. Furthermore, critical analysis of underlying factors overwhelmingly suggests that academic intervention coupled with sociocultural intervention may be a possible solution to help address this problem. Academic and sociocultural intervention strategies were designed and implemented in lower-division math courses through the National Science Foundation-funded project, “Building Capacity: Advancing Student Success in Undergraduate Engineering and Computer Science (ASSURE-US).” These strategies involved application-based math courses targeted explicitly at undergraduate engineering students. Results of academic intervention strategies in the lower-division math courses at one of the largest MSI demonstrate mixed effectiveness. The results of the academic intervention in lower-division Calculus I (N=150) show that 36% of students reported that the intervention was helpful and helped them learn math, while 38% were neutral. Overall, students reported having difficulty connecting the projects with the mathematics being taught. Similarly, only 10% of students expressed satisfaction with the redesigned intervention modules implemented in Integral Calculus II (N=90), while 52% were neutral. The sociocultural interventions include activities facilitated through the Student-Teacher Interaction Council. These activities include motivational speakers, exam preparation and stress-relief workshop, campus resources and college financial planning workshops, peer advising and learning communities, summer research, and faculty development and support. Results of the sociocultural intervention strategies show that 39% of students reported that the ASSURE-US project helped them identify role models in their discipline, while 34% reported that the project helped them identify and connect to a mentor. Students also reported higher awareness of campus resources, including mental health resources and academic support, with 89% and 90% of students reporting fully or partial understanding of these resources. The academic and sociocultural interventions of the ASSURE-US project were initially designed for in-person, hands-on, project-based, and student-faculty-involved activities; however, due to the COVID-19 pandemic, many of these activities were reimagined and redesigned for virtual instruction. The outcomes of this project so far were significantly impacted by the pandemic.

2. Improving STEM Education for Lower-division College Students at HSI by Utilizing Relevant Sociocultural and Academic Experiences: First-year Results from ASSURE-US Project

   https://doi.org/10.18260/1-2--34795

   Despite national efforts in increasing representation of minority students in STEM disciplines, disparities prevail. Hispanics account for 17.4% of the U.S. population, and nearly 20% of the youth population (21 years and below) in the U.S. is Hispanic, yet they account for just 7% of the STEM workforce. To tackle these challenges, the National Science Foundation (NSF) has granted a 5-year project – ASSURE-US, that seeks to improve undergraduate education in Engineering and Computer Science (ECS) at California State University, Fullerton. The project seeks to advance student success during the first two years of college for ECS students. Towards that goal, the project incorporates a very diverse set of approaches, such as socio-cultural and academic interventions. Multiple strategies including developing early intervention strategies in gateway STEM courses, creating a nurturing faculty-student interaction and collaborative learning environment, providing relevant, contextual-based learning experiences, integrating project-based learning with engineering design in lower-division courses, exposing lower-division students to research to sustain student interests, and helping students develop career-readiness skills. The project also seeks to develop an understanding of the personal, social, cognitive, and contextual factors contributing to student persistence in STEM learning that can be used by STEM faculty to improve their pedagogical and student-interaction approaches. This paper summarizes the major approaches the ASSURE-US project plans to implement to reduce the achievement gap and motivate ECS students to remain in the program. Preliminary findings from the first-year implementation of the project including pre- and post- data were collected and analyzed from about one hundred freshmen and sophomore ECS students regarding their academic experience in lower-division classes and their feedback for various social support events held by the ASSURE-US project during the academic year 2018-19. The preliminary results obtained during the first year of ASSURE-US project suggests that among the different ASSURE-US activities implemented in the first year, both the informal faculty-student interactions and summer research experiences helped students commit more to their major during their lower-division years. The pre-post surveys also show improvements in terms of awareness among ASSURE-US students for obtaining academic support services, understanding career options and pathways, and obtaining personal counseling services.

3. Innovative Learning Strategies to Engage Students Cognitively

   Aji, Chadia A.; Khan, Javed M. (July 2020, 2020 ASEE National Conference)

   The role of cognitive engagement in promoting deep learning is well established. This deep learning fosters attributes of success such as self-efficacy, motivation and persistence. However, the traditional chalk-and-talk teaching and learning environment is not conducive to engage students cognitively. The biggest impediment to implementing an environment for deep learning such as active-learning is the limited duration of a typical class period most of which is consumed by lecturing. In this paper, best practices and strategies for cognitive engagement of students in the classroom are discussed. Several lower level math and aerospace engineering courses were redesigned and offered during the academic year at a historically black university. The learning strategies in these redesigned courses included the “flipped” pedagogical model which allowed the integration of the active-learning strategy in the classroom. The research study is to determine the impact of these redesigned courses on student academic performance and persistence in STEM courses. The efficacy of the design of the flipped approach was also investigated. A between-group quasi-experimental research design was used for comparing student academic performance in traditional classroom (control group) and redesigned classroom (intervention group). A within-subject, repeated measures design was also used to assess the impact on the students’ self-regulated learning. A validated instrument was used to measure the effect of the redesigned learning environment on the motivational beliefs and self-regulated learning. Data on the academic performance of the students were collected. Analyses of these data indicated a significant impact on student academic performance. A positive change in student motivation and self-regulated learning was observed. Data analysis also validated the design of the intervention. This research is supported by NSF Grant# 1712156.

4. Creating Significant Learning Experiences in an Engineering Technology Bridge Course: a backward design approach

   Villalta-Cerdas, A.; Yildiz, F. (January 2022, 2022 ASEE Virtual Annual Conference Content Access)

   Academic bridge courses are implemented to impact students’ academic success by revising fundamental concepts and skills necessary to successfully complete discipline-specific courses. The bridge courses are often short (one to three weeks) and highly dense in content (commonly mathematics or math-related applications). With the support of the NSF-funded (DUE - Division of Undergraduate Education) STEM Center at Sam Houston State University (SHSU), we designed a course for upcoming engineering majors (i.e., first-year students and transfer students) that consists of a two-week-long pre-semester course organized into two main sessions. The first sessions (delivered in the mornings) were synchronous activities focused on strengthening student academic preparedness and socio-academic integration and fostering networking leading to a strong STEM learning community. The second sessions (delivered in the afternoons) were asynchronous activities focused on discipline-specific content knowledge in engineering. The engineering concepts were organized via eight learning modules covering basic math operations, applied trigonometry, functions in engineering, applied physics, introduction to statics and Microsoft Excel, and engineering economics and its applied decision. All materials in the course were designed by engineering faculty (from the chair of the department to assistant professors and lecturers in engineering) and one educational research faculty (from the department of chemistry). The course design process started with a literature review on engineering bridge courses to understand prior work, followed by surveying current engineering faculty to propose goals for the course. The designed team met weekly after setting the course goals over two semesters. The design process was initiated with backward design principles (i.e., start with the course goals, then the assessments, end with the learning activities) and continued with ongoing revision. The work herein presents this new engineering bridge course’s goals, strategy, and design process. Preliminary student outcomes will be discussed based on the course’s first implementation during summer 2021.

5. Scaffolding Spatial Abilities in Integral Calculus

   Davishahl, E.; Singleton, L.; Haskell, T.; Rupe, K.; Glen, L. (June 2022, 2022 ASEE Annual Conference & Exposition)

   This NSF-IUSE exploration and design project began in fall 2018 and features cross-disciplinary collaboration between engineering, math, and psychology faculty to develop learning activities with hands-on models and manipulatives. We are exploring how best to design these activities to support learners’ development of conceptual understanding and representational competence in integral calculus and engineering statics, two foundational courses for most engineering majors. A second goal is to leverage the model-based activities to scaffold spatial skills development in the context of traditional course content. As widely reported in the literature, well-developed spatial abilities correlate with student success and persistence in many STEM majors. We provided calculus students in selected intervention sections taught by four instructors at three different community colleges with take-home model kits that they could reference for a series of asynchronous learning activities. Students in these sections completed the Purdue Spatial Visualization Test: Rotations (PSVT:R) in the first and last weeks of their course. We also administered the assessment in multiple control sections (no manipulatives) taught by the same faculty. This paper analyzes results from fall 2020 through fall 2021 to see if there is any difference between control and intervention sections for the courses as a whole and for demographic subgroups including female-identifying students and historically-underserved students of color. All courses were asynchronous online modality in the context of the COVID-19 pandemic. We find that students in intervention sections of calculus made slightly larger gains on the PSVT:R, but this result is not statistically significant as a whole or for any of the demographic subgroups considered. We also analyzed final course grades for differences between control and intervention sections and found no differences. We found no significant effect of the presence of the model-based activities leading to increased PSVT:R gains or improved course grades. We would not extend this conclusion to face-to-face implementation, however, due primarily to the compromises made to adapt the curriculum from in-person group learning to asynchronous individual work and inconsistent engagement of the online students with the modeling activities.
