1. A MATLAB App to Introduce Chemical Engineering Design Concepts to Engineering Freshmen through a Pharmaceutical Dosing Case Study

   C. V. Eastep, G. K. ( April 2019 , Chemical engineering education)

   Hands-on design experiences to introduce first year students to chemical engineering are limited.[1] The College of Engineering, Architecture and Technology (CEAT) Summer Bridge Program at Oklahoma State University is a three-week camp designed to acclimate first year students to college life while providing calculus and physics preparatory short courses and design experiences from multiple disciplines in CEAT.[2] Since first-year students enjoy and value hands-on experiences,[2] we have developed a hands-on design module on the topic of pharmaceutical dosing for the chemical engineering portion of the Summer Bridge Program. We have taught the design module in nine sessions that were each two hours per day over three days during the 2015 – 2018 offerings of the Summer Bridge Program. The detailed lesson plan for using the design module to introduce mass balance and design concepts and an overview of the initial version of the MATLAB app were discussed in our previous ASEE conference proceedings paper.[2] In the present work, we discuss a redesigned MATLAB app (Figure 1) that has been expanded from two drugs and four cases to five drugs and eight cases. The new version of the MATLAB app is available as SB17CHE.mlappinstall on our GitHub repository.[3] Any future updates to the software will be released to the same archive. Additionally, we include a new section focused on our experiences in teaching chemical engineering design concepts using the MATLAB app and in responding to typical student questions. Our aim is to provide a tutorial for other educators interested in using the MATLAB app in their classroom or outreach activities related to chemical engineering design. For those interested in creating similar computational instructional tools, we have published details regarding the software implementation of the app and its documentation.[4]

   Biologically inspired design has become increasingly common in graduate and undergraduate engineering programs, consistent with an expanding emphasis by professional engineering societies on cross-disciplinary critical thinking skills and adaptive and sustainable design. However, bio-inspired engineering is less common in K-12 education. In 2019, the NSF funded a K-12 project entitled Biologically Inspired Design for Engineering Education (BIRDEE), to create socially relevant, accessible, and highly contextualized high school engineering curricula focusing on bio-inspired design. Studies have shown that women and underrepresented minorities are drawn to curricula, courses, and instructional strategies that are integrated, emphasize systems thinking, and facilitate connection building across courses or disciplines. The BIRDEE project also seeks to interest high school girls in engineering by providing curricula that incorporate humanistic, bio-inspired engineering with a focus on sustainable and authentic design contexts. BIRDEE curricula integrate bio-inspired design into the engineering design process by leveraging design tools that facilitate the application of biological concepts to design challenges. This provides a conceptual framework enabling students to systematically define a design problem, resulting in better, more well-rounded problem specifications. The professional development (PD) for the participating teachers include six-week-long summer internships in university research laboratories focused on biology and bio-inspired design. The goal of these internships is to improve engineering teachers’ knowledge of bio-inspired design by partnering with cutting-edge engineers and scientists to study animal features and behaviors and their applications to engineering design. However, due to COVID-19 and research lab closures in the summer of 2020, the research team had to transfer the summer PD experience to an online setting. An asynchronous, quasi-facilitated online course was developed and delivered to teachers over six weeks. In this paper, we will discuss online pedagogical approaches to experiential learning, teaching bio-inspired design concepts, and the integration of these approaches in the engineering design process. Central to the online PD design and function of each course was the use of inquiry, experiential and highly-collaborative learning strategies. Preliminary results show that teachers appreciated the aspects of the summer PD that included exploration, such as during the “Found Object” activity, and the process of building a prototype. These activities represented experiential learning opportunities where teachers were able to learn by doing. It was noted throughout the focus group discussions that such opportunities were appreciated by participating teachers. Teachers indicated that the experiential learning components of the PD allowed them to do something outside of their comfort zone, inspired them to do research that they would not have done outside of this experience, and allowed them to “be in the student's seat and get hands-on application”. By participating in these experiential learning opportunities, teachers were also able to better understand how the BIRDEE curriculum may impact students’ learning in their classrooms

3. Evaluation of Summer Camp Recruitment Methods and Campers’ Perceptions of Engineering (Evaluation, Diversity)

   Fleming, Gabriella Coloyan ; Fernandez, Kiersten Elyse ; Julien, Christine ; Mastronardi, Marialice ( June 2023 , 2023 ASEE Annual Conference & Exposition)

   Program leaders put a tremendous amount of thought into how they recruit students for engineering summer camps. Recruitment methods can include information sessions, established partnerships with school districts, and teacher or school counselor nominations of students. This study seeks to assess if the methods used to recruit students broaden participation or have any impact on students’ perceptions of engineering. Two identical week-long summer camps were hosted by the University of Texas at Austin (UT Austin) in the summer of 2022. Camps were entirely free for all campers. A specific goal of the camp was to promote engineering as a career pathway for students from groups that have been historically excluded from STEM majors. Campers were rising 8th and 9th grade students in two cities near UT Austin; this age was intentionally identified as students who have sufficient STEM backgrounds to engage in meaningful engineering design challenges, and who are also at a critical inflection point with respect to decisions that put them on a trajectory to study engineering in college. Summer camp topics ranged from additive manufacturing to the chemical properties of water proofing, and students did activities such as constructing a prosthetic limb from recovered materials or designing an electronic dance game pad. In one camp session, students primarily found out about the camp by being nominated by counselors at their schools, with an intentional focus on recruiting students who might not otherwise be exposed to engineering. In the other camp session, parents signed up campers after hearing about the camp via information sent through the schools. All students who applied were accepted to the camps. Identical pre- and post-camp surveys asked campers questions about their knowledge of what engineers do, their interest in math and science, and what factors are important to them when choosing a career. Survey analysis showed that there were statistically significant differences in answers to questions between the groups in the pre-camp surveys, but post-camp surveys show that these differences disappeared after participating in the summer camp. Students whose parents directly enrolled them in the camp had higher pre-camp interest in science and technology; thus, counselor nominations may be a method to recruit students who might not have been interested in engineering had they not attended the camp. Additionally, prior to participating, campers recruited via counselor nominations had a narrower view of what engineers do than the parent-enrolled campers, but after camp the two groups had similar perceptions of what engineers do. The results of this study confirm literature findings regarding the importance of exposing young learners to engineering as a profession and broaden their views of opportunities in this field. The recruitment methods used for these camps show that nomination-based recruitment methods have the potential for greater impact on changing students’ engineering trajectories.

4. Engaging Future Engineers through Active Participation in Diversity, Equity, Inclusion, and Belonging

   Chandra, K. ; Lewis, S. ; Tripathy, S.T. ( June 2023 , Proceedings of the 2023 ASEE Annual Conference & Exposition)

   It is important for future engineers to understand themselves in relation to the many cultural influences they may encounter during their career, and to confront their own biases when interacting with colleagues whose cultural backgrounds are different from their own. This paper describes and evaluates a series of nine diversity, equity, and inclusion (DEI) workshops developed and implemented during the summer of 2022 for high school and entering first-year college students enrolled in the Research, Academics, and Mentoring Pathways (RAMP) six week engineering summer bridge program at University of Massachusetts Lowell. The workshops incorporated activities designed to create an environment fostering respect, belonging, and acceptance to make teamwork more inclusive and effective. Each workshop was based on collaborative learning and used a broad range of strategies to engage students as active participants in learning about diversity, equity, and inclusion within the context of teamwork. To develop the workshops, the facilitators aligned the activities with key themes from chapters in the book From Athletics to Engineering: 8 Ways to Support Diversity, Equity, and Inclusion for All [1]. The summer bridge program was evaluated using quantitative and qualitative data collected throughout the program and upon its conclusion tracking students’ reactions and levels of engagement in each of the program components. This included a pre-survey, mid-semester survey, post-survey, and weekly journal prompts on Google Classroom. We also used the Universality-Diversity scale [2] to measure any pre-post changes in students’ attitudes towards diversity. With regard to the workshops, an analysis of student responses indicated a high level of satisfaction and sense of accomplishment. Students reported they enjoyed getting to know each other better and that the DEI activities were interactive, educational, and engaging.

5. Summer Bridge Programming for Incoming First-Year Students at Three Public Urban Research Universities

   Howland Cummings, M. ; Darbeheshti, M. ; Ivey, S. ; Stewart, C. ; Russomanno, D. ; King, D. ; Goodman, K. ; Campbell, J. ; Altman, T. ; Jacobson, M. ; et al ( August 2022 , ASEE Annual Conference proceedings)

   This Complete Evidence-based Practice paper will describe how three different public urban research universities designed, executed, and iterated Summer Bridge programming for a subset of incoming first-year engineering students over the course of three consecutive years. There were commonalities between each institution’s Summer Bridge, as well as unique aspects catering to the specific needs and structures of each institution. Both these commonalities and unique aspects will be discussed, in addition to the processes of iteration and improvement, target student populations, and reported student outcomes. Finally, recommendations for other institutions seeking to launch or refine similar programming will be shared. Summer Bridge programming at each of the three institutions shared certain communalities. Mostly notably, each of the three institutions developed its Summer Bridge as an additional way to provide support for students receiving an NSF S-STEM scholarship. The purpose of each Summer Bridge was to build community among these students, prepare them for the academic rigor of first-year engineering curriculum, and edify their STEM identity and sense of belonging. Each Summer Bridge was a 3-5 day experience held in the week immediately prior to the start of the Fall semester. In addition to these communalities, each Summer Bridge also had its own unique features. At the first institution, Summer Bridge is focused on increasing college readiness through the transition from summer break into impending coursework. This institution’s Summer Bridge includes STEM special-interest presentations (such as biomedical or electrical engineering) and other development activities (such as communication and growth mindset workshops). Additionally, this institution’s Summer Bridge continues into the fall semester via a 1-credit hour First Year Seminar class, which builds and reinforces student networking and community beyond the summer experience. At the second institution, all students receiving the NSF S-STEM scholarship (not only those who are first-year students) participate in Summer Bridge. This means that S-STEM scholars at this institution participate in Summer Bridge multiple years in a row. Relatedly, after the first year, Summer Bridge transitioned to a student-led and student-delivered program, affording sophomore and junior students leadership opportunities, which not only serve as marketable experience after graduation, but also further builds their sense of STEM identity and belonging. At the third institution, a special focus was given to building community. This was achieved through several means. First, each day of Summer Bridge included a unique team-oriented design challenge where students got to work together and know each other within an engineering context, also reinforcing their STEM identities. Second, students at this institution’s Summer Bridge met their future instructors in an informal, conversational, lunch setting; many students reported this was one of their favorite aspects of Summer Bridge. Finally, Summer Bridge facilitated a first connect between incoming first-year students and their peer mentors (sophomore and junior students also receiving the NSF S-STEM scholarship), with whom they would meet regularly throughout the following fall and spring semesters. Each of the three institutions employed processes of iteration and improvement for their Summer Bridge programming over the course of two or three consecutive years. Through each version and iteration of Summer Bridge, positive student outcomes are demonstrated, including direct student feedback indicating built community among students and the perception that their time spent during Summer Bridge was valuable. Based on the experiences of these three institutions, as well as research on other institutions’ Summer Bridge programming, recommendations for those seeking to launch or refine similar Summer Bridge programming will also be shared.
