1. ”What you bring matters”: A Comparative Case Study of Middle School Engineering Teachers’ Pedagogical Content Knowledge (Fundamental)

   Gale, J; Baptiste_Porter, D; Alemdar, M; Newton, S; Rehmat, A; Choi, J (June 2025, American Society for Engineering Education)

   Pre-college engineering teachers bring unique backgrounds to their teaching practice. Many engineering teachers follow a non-traditional route to teaching engineering, often coming to engineering from teaching other subjects or from careers in other fields. Among the many variations influencing engineering teaching practices is pedagogical content knowledge (PCK), defined as the “the knowledge of, reasoning behind, and enactment of the teaching of particular topics in a particular way with particular students for particular reasons for enhanced student outcomes [1]”. This multiple case study explores the PCK of five middle school engineering teachers implementing the same middle school engineering curriculum, STEM-ID. The 18- week STEM-ID curriculum engages students in contextualized challenges that incorporate foundational mathematics and science practices and advanced manufacturing tools such as computer aided design (CAD) and 3D printing, while introducing engineering concepts like pneumatics, aeronautics, and robotics. Drawing on observation and interview data collected over the course of two semester-long implementations of STEM-ID, the study addresses the research question: What variations in PCK are evident among engineering teachers with different professional backgrounds and levels of experience? Five teachers were purposively selected from a larger group of teachers implementing the curriculum because they represent a range of professional backgrounds: one veteran engineering teacher, one former Math teacher, one former Science teacher, one former English/Language Arts teacher, and one novice teacher with a background in the software industry. The study utilizes the Refined Consensus Model of PCK to investigate connections between teacher backgrounds, personal PCK (pPCK), the personalized professional knowledge held by teachers, and enacted PCK (ePCK), the knowledge teachers draw on to engage in pedagogical reasoning while planning, teaching, and reflecting on their practice. Observation, interview, and survey data were triangulated to develop narrative case summaries describing each teacher’s PCK, which were then subjected to cross-case analysis to identify patterns and themes across teachers. Findings describe how teachers’ backgrounds translated into diverse forms of pPCK that informed the pedagogical moves and decisions teachers made as they implemented the curriculum (ePCK). Regardless of the previous subject taught (math, science, or ELA), teachers routinely drew upon their pPCK in other subjects as they facilitated the engineering design process. Teachers with previous experience teaching math or science tended to be more likely than others to foreground the integration of math or science within the curriculum. Comparison of ePCK observed as teachers implemented the curriculum revealed that, in spite of having a more fully developed pPCK in teaching engineering, the veteran engineering teacher did not exhibit more sophisticated ePCK than novice engineering teachers. In addition to contributing to the field’s understanding of engineering teachers’ PCK, these findings hold implications for the recruitment, retention, and professional development of engineering teachers.

2. Just keep swimming: Increasing resilience of STEM preservice teachers during COVID-19

   Catherine M. Lussier University of California, Riverside Ashley M. (March 2023, Journal of instructional pedagogies)

   A substantial achievement gap between K-12 English learners (ELs) and non-ELs in science, technology, engineering, and mathematics (STEM) content areas exists, as indicated by national assessments of student outcomes. Considering the expected steady increase in students who are ELs in the U.S., determining methods for addressing this achievement gap is of immediate concern. Research has indicated this gap may be exacerbated by lack of adequate teacher preparation, specifically in STEM fields, to effectively teach students who are culturally and linguistically diverse (CLD). Founded in previous research about effective teacher preparation, the current case study pilots and reports on a model of early STEM preservice teacher training that integrates: knowledge of language development for ELs, early experiences with CLD learners, and professional development activities that guide the implementation of STEM pedagogical methods. Five STEM preservice teachers participated in a year-long supplemental training program focused on adapting STEM instruction for ELs. Components of the supplemental program included: (a) coursework extending teacher knowledge of EL language development, (b) fieldwork providing early exposure to research-based teaching experiences with EL students, and (c) professional development guiding the creation of hands-on STEM curriculum for diverse learners. Five secondary preservice teachers experienced increases in self-efficacy, growth in STEM instructional practices, and greater motivation for teaching in high-need schools. Results will inform educational models for improving STEM-EL teaching, thereby addressing a crucial need to serve the growing national population of underserved students.

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

   Nichol, C.; Crawford, C. A.; Barr, C.; Cerda, I. (January 2021, ASEE Annual Conference proceedings)

   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.

4. Implementing an Ecosystem to Expand Capabilities and Opportunities for STEM-Scholars

   Lopez Del Puerto, C. (June 2023, 2023 ASEE Annual Conference & Exposition)

   The population of students in Puerto Rico that has enrolled in higher education within the last six years has been severely affected by a compound effect of the many major humanitarian crises, including a deteriorated economy since the 2006 Great Recession, Hurricanes Irma and Maria in 2017, earthquakes in 2019 and 2020, the ongoing COVID-19 pandemic since 2020, and Hurricane Fiona in 2022. To ensure that students can cope with the aftermath of these natural disasters, the following programs were conceived: The Ecosystem to Expand Capabilities and Opportunities for STEM-Scholars (EECOS), the Resilient Infrastructure and Sustainability Education Undergraduate Program (RISE-UP) and The Noyce Teacher Scholars Program – (NoTeS), all three programs are funded by the National Science Foundation. EECOS developed a support ecosystem that consists of three elements: academic support, socio-emotional support, and financial support. NoTeS. provides talented Hispanic low-socioeconomic bilingual undergraduate or recently graduated STEM majors and professionals up to two years of scholarship funding as well as academic and professional support as they complete the requirements to obtain teacher certification to become K-12 math and science teachers. This program seeks to increase the number of K-12 teachers with strong STEM content knowledge to fill the need for teachers in high-need school districts. RISE-UP was conceptualized to educate architecture and engineering students to work in interdisciplinary teams to provide resilient and sustainable design and construction solutions to infrastructure challenges. To date, EECOS has directly impacted XX students and graduated XXX students. NoTeS has helped nineteen scholars and ten affiliates (participants of the activities without the scholarship) partake. Eight of the nine alums scholars now work as math or science teachers in a high-needs school. RISE-UP has had 127 scholars who are enrolled or have completed the RISE-UP curricular sequence. This paper provides effective practices and a baseline characterization that universities can use to help students overcome the effects of natural disasters and promote student success using ecosystems of support that expand capabilities and opportunities, particularly for STEM scholars.

5. Finding their voice: Support mechanisms to engage and empower future mathematics teachers.

   Gomez Johnson, K. (July 2019, Proceedings of the Eighth Annual Mathematics Teacher Education Partnership Conference)

   Smith, W. M. (Ed.)

   The NebraskaMATH Omaha Noyce Partnership Scholarship awards scholarships funded by the National Science Foundation (NSF) to undergraduate students interested in mathematics education at the University of Nebraska at Omaha (UNO). Scholars, who are dual mathematics and secondary education majors, are engaged and supported by Noyce faculty to not only excel in their college coursework and career preparation, but also to serve the university and community through teaching assistantships and STEM community outreach. The main goal of this program is to strengthen and expand the pipeline for preparing high-quality teachers of mathematics to better meet the responsibilities and demands of local school districts, particularly those serving students with high-need. Cross-campus collaborations between the departments of teacher education and mathematics co-constructed the Noyce infrastructure to emphasize and share the development of future, high-quality secondary mathematics teachers (Mathematics Teacher Education Partnership, 2014). This paper describes our program’s unique design and implementation features aimed to empower, engage, and extend the talents of our undergraduate students. We share lessons learned and recommendations from faculty and participants regarding decisions and facets of the program considered to be most influential in STEM teacher and leadership development.
