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).

Increasing STEM Engagement in Minority Middle School Boys through Making
African-American and Hispanic males are significantly underrepresented in STEM. While youth start narrowing their career choices in middle school, National Maker programs rarely specifically target minority males. Four Historically Black Colleges/Universities (HBCUs), in partnership with The Verizon Foundation, have established Maker communities in underserved urban and rural communities. The Minority Male Maker Program allows middle school students and their teachers to develop science, technology, engineering, and mathematics (STEM) skills while expressing their creativity. The long term goals of this project are to increase participant interest in STEM careers and college attendance. In the short term, we anticipate increased technology proficiency, STEM engagement and academic achievement. Additional outcomes include increased teacher and mentor understanding of STEM instruction delivery and mentorship. Panelists will discuss disparities facing men of color and a new National program designed to provide early exposure to STEM. Recommendations for developing programs targeting minority male students will be discussed.

null (Ed.)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.more » « less

The percentage of minority males in the science, technology, engineering, and mathematics (STEM) workforce is about half of their representation in the US population. Roadblocks that continue to challenge minority males include: disparity in access to high quality STEM educational resources, a lack of role models, and a shortage of highly trained, minority STEM educators. This work describes an INCLUDES Design and Development Launch Pilot that builds on an existing regional partnership of four Historically Black Colleges and Universities (HBCUs) that are working together to improve STEM outcomes for middle school minority male students. Using collective impact-style approaches such as implementing mutually reinforcing activities through a Network Improvement Community (NIC) these partners are addressing the larger goal of improving STEM achievement in minority males, particularly in middle school. Activities of the NIC included a workshop to share best practices and define the NIC, workgroups to engage in improvement cycles, a website that will contribute to the knowledge base regarding effective strategies for enhancing STEM educational opportunities for minority males, and webinars. The project partners have also created a roadmap for a NIC to address the challenges described above. This paper describes a work in progress and will provides an update on the NIC to the broader engineering community.more » « less
