   Designing a Curriculum to Broaden Middle School Students’ Ideas and Interest in Engineering As the 21st century progresses, engineers will play critical roles in addressing complex societal problems such as climate change and nutrient pollution. Research has shown that more diverse teams lead to more creative and effective solutions (Smith-Doerr et al., 2017). However, while some progress has been made in increasing the number of women and people of color, 83% of employed engineers are male and 68% of engineers are white (NSF & NCSES, 2019). Traditional K–12 approaches to engineering often emphasize construction using a trial-and-error approach (ASEE, 2020). Although this approach may appeal to some students, it may alienate other students who then view engineering simply as “building things.” Designing engineering experiences that broaden students’ ideas about engineering, may help diversify the students entering the engineering pipeline. To this end, we developed Solving Community Problems with Engineering (SCoPE), an engineering curriculum that engages seventh-grade students in a three-week capstone project focusing on nutrient pollution in their local watershed. SCoPE engages students with the problem through local news articles about nutrient pollution and images of algae covered lakes, which then drives the investigation into the detrimental processes caused by excess nutrients entering bodies of water from sources such as fertilizer and wastewater. Students research the sources of nutrient pollution and potential solutions, and use simulations to investigate key variables and optimize the types of strategies for effectively decreasing and managing nutrient pollution to help develop their plans. Throughout the development process, we worked with a middle school STEM teacher to ensure the unit builds upon the science curriculum and the activities would be engaging and meaningful to students. The problem and location were chosen to illustrate that engineers can solve problems relevant to rural communities. Since people in rural locations tend to remain very connected to their communities throughout their lives, it is important to illustrate that engineering could be a relevant and viable career near home. The SCoPE curriculum was piloted with two teachers and 147 seventh grade students in a rural public school. Surveys and student drawings of engineers before and after implementation of the curriculum were used to characterize changes in students’ interest and beliefs about engineering. After completing the SCoPE curriculum, students’ ideas about engineers’ activities and the types of problems they solve were broadened. Students were 53% more likely to believe that engineers can protect the environment and 23% more likely to believe that they can identify problems in the community to solve (p < 0.001). When asked to draw an engineer, students were 1.3 times more likely to include nature/environment/agriculture (p < 0.01) and 3 times more likely to show engineers helping people in the community (p< 0.05) Additionally, while boys’ interest in science and engineering did not significantly change, girls’ interest in engineering and confidence in becoming an engineer significantly increased (Cohen’s D = 0.28, p<0.05). The SCoPE curriculum is available on PBS LearningMedia: https://www.pbslearningmedia.org/collection/solving-community-problems-with-engineering/ This project was funded by NSF through the Division of Engineering Education and Centers, Research in the Formation of Engineers program #202076.

2. Engagement in Practice: Lessons Learned Partnering with Science Educators and Local Engineers in Rural Schools

   Lesko, H. L. ; Grohs, J. R. ; Matusovich, H. M. ; Kirk, G. R. ; Carrico, C. ; van Montfrans, V. ; Gillen, A. L. ; Paradise, T. ; Blackowski, S. A. ; Baum, L. M. ( June 2018 , ASEE Annual Conference proceedings)

   Our NSF-funded ITEST project focuses on the collaborative design, implementation, and study of recurrent hands-on engineering activities with middle school youth in three rural communities in or near Appalachia. To achieve this aim, our team of faculty and graduate students partner with school educators and industry experts embedded in students’ local communities to collectively develop curriculum to aim at teacher-identified science standard and facilitate regular in-class interventions throughout the academic year. Leveraging local expertise is especially critical in this project because family pressures, cultural milieu, and preference for local, stable jobs play considerable roles in how Appalachian youth choose possible careers. Our partner communities have voluntarily opted to participate with us in a shared implementation-research program and as our project unfolds we are responsive to community-identified needs and preferences while maintaining the research program’s integrity. Our primary focus has been working to incorporate hands-on activities into science classrooms aimed at state science standards in recognition of the demands placed on teachers to align classroom time with state standards and associated standardized achievement tests. Our focus on serving diverse communities while being attentive to relevant research such as the preference for local, stable jobs attention to cultural relevance led us to reach out to advanced manufacturing facilities based in the target communities in order to enhance the connection students and teachers feel to local engineers. Each manufacturer has committed to designating several employees (engineers) to co-facilitate interventions six times each academic year. Launching our project has involved coordination across stakeholder groups to understand distinct values, goals, strengths and needs. In the first academic year, we are working with 9 different 6th grade science teachers across 7 schools in 3 counties. Co-facilitating in the classroom are representatives from our project team, graduate student volunteers from across the college of engineering, and volunteering engineers from our three industry partners. Developing this multi-stakeholder partnership has involved discussions and approvals across both school systems (e.g., superintendents, STEM coordinators, teachers) and our industry partners (e.g., managers, HR staff, volunteering engineers). The aim of this engagement-in-practice paper is to explore our lessons learned in navigating the day-to-day challenges of (1) developing and facilitating curriculum at the intersection of science standards, hands-on activities, cultural relevancy, and engineering thinking, (2) collaborating with volunteers from our industry partners and within our own college of engineering in order to deliver content in every science class of our 9 6th grade teachers one full school day/month, and (3) adapting to emergent needs that arise due to school and division differences (e.g., logistics of scheduling and curriculum pacing), community differences across our three counties (e.g., available resources in schools), and partner constraints.

3. Integrating Professional Mentorship with a 3D-Printing Curriculum to Help Rural Youth Forge STEM Career Connections.

   Bhaduri, S. ( July 2021 , 2021 ASEE Virtual Annual Conference.)

   Economically disadvantaged youth residing in mountain tourist communities represent an important and understudied rural population. These communities typically include a large percentage of children that are English language learners. Our NSF STEM Career Connections project, A Model for Preparing Economically-Disadvantaged Rural Youth for the Future STEM Workplace, investigates strategies that help middle school youth in these communities to envision a broader range of workforce opportunities, especially in STEM and computing careers. This poster highlights the initial findings of an innovative model that involves working with local schools and community partners to support the integration of local career contexts, engineering phenomena, 3D printing technologies, career connections, and mentorship into formal educational experiences to motivate and prepare rural youth for future STEM careers. We focus on select classrooms at two middle schools and describe the implementation of a novel 3D printing curriculum during the 2020-2021 school-year. Two STEM teachers implemented the five-week curriculum with approximately 300 students per quarter. To create a rich inquiry-driven learning environment, the curriculum uses an instructional design approach called storylining. This approach is intended to promote coherence, relevance, and meaning from the students’ perspectives by using students’ questions to drive investigations and lessons. Students worked towards answering the question: “How can we support animals with physical disabilities so they can perform daily activities independently?” Students engaged in the engineering design process by defining, developing, and optimizing solutions to develop and print prosthetic limbs for animals with disabilities using 3D modeling, a unique augmented reality application, and 3D printing. In order to embed connections to STEM careers and career pathways, some students received mentorship and guidance from local STEM professionals who work in related fields. This poster will describe the curriculum and its implementation across two quarters at two middle schools in the US rural mountain west, as well as the impact on students’ interest in STEM and computing careers. During the first quarter students engaged in the 3D printing curriculum, but did not have access to the STEM career and career pathway connections mentorship piece. During the second quarter, the project established a partnership with a local STEM business -- a medical research institute that utilizes 3D printing and scanning for creating human surgical devices and procedures -- to provide mentorship to the students. Volunteers from this institute served as ongoing mentors for the students in each classroom during the second quarter. The STEM mentors guided students through the process of designing, testing, and optimizing their 3D models and 3D printed prosthetics, providing insights into how students’ learning directly applies to the medical industry. Different forms of student data such as cognitive interviews and pre/post STEM interest and spatial thinking surveys were collected and analyzed to understand the benefits of the career connections mentorship component. Preliminary findings suggest the relationship between local STEM businesses and students is important to motivate youth from rural areas to see themselves being successful in STEM careers and helping them to realize the benefits of engaging with emerging engineering technologies.

4. Long-Term Outcomes of RET Programs on Female and Minority Student High School Graduation Rates and Undergraduate STEM Major Rates (Fundamental)

   Research Experience for Teachers (RET) programs are National Science Foundation (NSF) funded programs designed to provide K- 12 Science, Technology, Engineering, and Mathematics (STEM) teachers with immersive, hands-on research experiences at Universities around the country. The NSF RET in nanotechnology encourages teachers to translate cutting-edge research into culturally relevant Project-Based Learning (PjBL) and engineering curriculum. Traditionally, the evaluation of RET programs focuses on the growth and development of teacher self-efficacy, engineering content knowledge gains, or classroom implementation of developed curriculum materials. However, reported methods for evaluating the impact of RETs on their female, minority student populations' high school graduation and undergraduate STEM major rates are limited. This study's objective was to compare RET high school student graduation rates and undergraduate STEM major rates across gender, race, and ethnicity to a comparison sample to determine the RET program's long-term impact on students' likelihood of pursuing STEM careers. The approach of collecting and analyzing the Texas Education Research Center Database (EdRC) data is a novel methodology for assessing RET programs' effectiveness on students. The EdRC is a repository of K-12 student data from the Texas Education Agency (TEA) and Higher Education data from the Texas Higher Education Coordinating Board (THECB). This joint database contains demographic, course registration, graduation, standardized testing, and college major, among others, for all students that attended a K-12 public school in Texas and any college in Texas, public or private. The RET program participants at Rice University (2010 – 2018) taught numerous students, a sample size of 11,240 students. A propensity score matching generated the student comparison group within the database. Students' school campus, gender, race/ethnic status, and English proficiency status were applied to produce a graduation comparison sample size of 11,240 students of Non-RET participants. Linking the TEA database to the THECB database resulted in college STEM participants and comparison sample sizes of 4,029 students. The project team conducted a logistic regression using RET status to predict high school graduation rates as a whole and by individual variables: gender, Asian American, Black, Caucasian, and Latinx students. All models were significant at p less than 0.05, with models in favor of students RET teachers. The project team conducted a logistic regression using RET status to predict student STEM undergraduate major rates as a whole and by individual variables: Gender, Asian American, Black, Caucasian, and Latinx students. African American and Caucasian models were significant at p less than 0.05; Gender, Asian American, and Latinx models were marginally significant (0.05 less than p greater than 0.1), where RET students had higher STEM major rates than matched controls. The findings demonstrate that RET programs have a long-term positive impact on the students' high school graduation rates and undergraduate STEM major rates. As teachers who participate in the RET programs are more likely to conduct courses using PjBL strategies and incorporate real-world engineering practices, female and minority students are more likely to benefit from these practices and seek careers utilizing these skills.

5. Biologically Inspired Design For Engineering Education: Online Teacher Professional Learning (Evaluation)

   https://doi.org/10.18260/1-2--36749  

   Alemdar, Meltem ; Ehsan, Hoda ; Cappelli, Christopher ; Kim, Euisun ; Moore, Roxanne ; Helms, Michael ; Rosen, Jeffrey ; Weissburg, Marc ( July 2021 , American Society of Engineering education)

   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
