Despite recent progress in the adoption of engineering at the K-12 level, the scarcity of high-quality engineering curricula remains a challenge. With support from a previous NSF grant, our research team iteratively developed the three-year middle school engineering curricula, STEM-ID. Through a series of contextualized challenges, the 18-week STEM-ID curricula incorporate foundational mathematics and science skills and practices and advanced manufacturing tools such as computer aided design (CAD) and 3D printing, while introducing engineering concepts like pneumatics, aeronautics, and robotics.
Our current project, supported by an NSF DRK-12 grant, seeks to examine the effectiveness of STEM-ID when implemented in diverse schools within a large school district in the southeastern United States. This paper will present early findings of the project’s implementation research conducted over two school years with a total of ten engineering teachers in nine schools. Guided by the Innovation Implementation framework (Century & Cassata, 2014), our implementation research triangulates observation, interview, and survey data to describe overall implementation of STEM-ID as well as implementation of six critical components of the curricula: engaging students in the engineering design process (EDP), math-science integration, collaborative group work, contextualized challenges, utilization of advanced manufacturing technology, and utilization of curriculum materials. Implementation data provide clear evidence that each of the critical components of STEM-ID were evident as the curricula were enacted in participating schools. Our data indicate strong implementation of four critical components (utilization of materials, math-science integration, collaborative group work, and contextualized challenges) across teachers. Engaging students in the EDP and advanced-manufacturing technology were implemented, to varying degrees, by all but two teachers. As expected, implementation of critical components mirrored overall implementation patterns, with teachers who completed more of the curricula tending to implement the critical components more fully than those who did not complete the curricula. In addition to tracking implementation of critical components, the project is also interested in understanding contextual factors that influence enactment of the curricula, including characteristics of the STEM-ID curricula, teachers, and organizations (school and district). Interview and observation data suggest a number of teacher characteristics that may account for variations in implementation including teachers’ organization and time management skills, self-efficacy, and pedagogical content knowledge (PCK). Notably, prior teaching experience did not consistently translate into higher completion rates, emphasizing the need for targeted support regardless of teachers' backgrounds. This research contributes valuable insights into the challenges and successes of implementing engineering curricula in diverse educational settings.

Exploring How Contextual Factors Influence the Implementation of Middle School Engineering Curricula (Fundamental)
Through the semester-long engineering curricula, middle school students complete a series of contextualized challenges that integrate foundational mathematics and science, introduce advanced manufacturing tools (CAD, 3-D printing), and engage students in the engineering design process. Funded by a National Science Foundation (NSF) DRK12 grant, our project is in the process of scaling the curricula in a large urban school district. Over the previous two years, the project has enlisted two cohorts of engineering teachers to implement the curricula in nine middle schools. In addition to understanding whether and how the critical components of the curricula are implemented in diverse school settings, our research team’s fidelity of implementation research investigates contextual factors that help explain why teachers and students engaged with the curricula the way they do. For this line of inquiry, we draw upon the Factor Framework (Century and Cassata, 2014; Century et al. 2012), which provides a comprehensive set of potential factors known to influence implementation of educational innovations. The framework organizes these implementation factors into five categories: characteristics of the innovation, characteristics of individual users, characteristics of the organization, elements of the environment, and networks. After consulting this framework to identify potential factors likely to influence the implementation, we analyzed teacher interview and classroom observation data collected over the course of three semesters of implementation to describe the degree to which various contextual factors either facilitated or limited implementation. Our data indicate three categories of factors influencing implementation: characteristics of the curriculum, characteristics of users (teachers and students), and characteristics of organizations (district, schools). Characteristics of the curriculum that facilitated implementation included features of the curricula and professional development including the perceived effectiveness of the curricula, the adaptability of the curricula, and the degree to which professional learning sessions provided adequate preparation for implementation. Characteristics of teachers identified as facilitating implementation included pedagogical content knowledge, self-efficacy, resourcefulness, and organizational and time management skills. Teachers reported that student interest in the curriculum challenges and STEM, more generally, was another facilitating factor whereas, to varying degrees, disruptive student behavior and students’ lack of foundational mathematics skills were reported as limiting factors. Teachers highlighted specific technological challenges, such as software licensing issues, as limiting factors. Otherwise, we found that teachers generally had sufficient resources to implement the curricula including adequate physical space, technological tools, and supplies. Across teachers and schools, we found that, overall, supportive school and district leadership facilitated implementation. In spite of an overall high level of support in participating schools, we did identify school and district policies with implications for implementation including school-wide scheduling and disciplinary policies that limited instructional time, policies for assigning and moving students among elective courses, and district-wide expectations for assessment and teaching certain additional engineering activities. We believe the findings of this study will be of interest to other researchers and practitioners exploring how engineering education innovations unfold in diverse classrooms and the array of factors that may account for variations in implementation patterns.

A research-practice partnership (RPP) used a teacher co-design process, supported by equity-focused professional development, to create an elementary-level curriculum that integrates content, practices, and learning progressions from state computing standards with other standards-based curricula. Most district students are part of historically marginalized groups and the RPP chose to develop an equity and inclusion-focused curriculum that would be taught in all elementary classrooms to all students. Twelve teacher teams, supported by researchers and ELL and SPED specialists, designed, piloted, and documented 23 modules of 4-8, 45-minute lessons across K-5. Early adopter teachers followed the pilots and implemented the modules in their classrooms with the goal of facilitating adoption by all elementary classroom teachers. After being interrupted by the pandemic, the RPP developed a strategy where principals in cohorts of schools agreed to collaborate with RPP school-based lead teachers to establish professional learning communities (PLCs) to support classroom implementation of the modules. Eleven schools participated in a 2021-22 cohort and nine more schools joined in 2022-23. Centering equity, PLCs, and quality module documentation and materials are key to sustaining and evolving the CSforAll curriculum. The modules were revised based on feedback obtained from ELL and SPED specialists, early adopters, teacher coordinators, researchers, and district curriculum directors. Using a large data set of meeting and classroom observation records, interviews, field notes, focus groups, surveys, and module documentation, we track the evolution of the curriculum and provide a detailed analysis of one module as an example.more » « less

null (Ed.)Pre-college engineering education has been on a sharp rise in the United States. Numerous schools offer some variation of an engineering curricula, but challenges remain regarding socio-cultural perceptions of engineering, teacher training, curricular alignment with state standards, and policy decisions. Many past studies have examined students’ and teachers’ knowledge, perceptions, and beliefs regarding pre-college engineering instruction. Few studies have investigated the viewpoints of school administrators, or state and district personnel. This qualitative study investigated perspectives of three such administrators in a southwest US public high school. The school was one of nine pilot locations offering a new engineering course designed to ‘demystify’ engineering for high school students and teachers from all walks of life. Results converged around four major themes: 1) relevance and current state of pre-college engineering education, 2) teacher certification and professional development, 3) industry connections, and 4) expectations of pre-college engineering curricula. The resulting themes shed light on long standing issues affecting adoption of engineering at the pre-college level and highlight a few areas that upcoming pre-college engineering education programs could focus on.more » « less

Development of innovative curriculum materials is a mainstay strategy in research-driven classroom interventions and teacher professional development. Yet even when curricular materials are co-developed by teachers planning to implement the materials, they still must navigate the unique needs and constraints of their classrooms. This study explores differentiated enactment of a co-developed place-based middle school energy literacy unit. The unit uses the school building as a place-based resource to increase student awareness and understanding of fundamental energy concepts, impacts and interactions of natural and human-made energy systems, and considerations for energy efficient building features through engineering design. This multiple-case explores how five teachers across four middle schools in the same school district enacted the unit. Each teacher’s enactment was characterized using Coburn’s (2004) five levels, which are: rejection (materials not enacted), symbolic (materials implemented superficially), parallel structures (materials are implemented with existing practices), assimilation (adopts the materials but transforms materials to fit internal and external factors), and accommodation (enacts the materials with minor changes). We observed symbolic, assimilation, accommodation, and rejection across the teachers, with enactment modes varying across different phases of unit implementation. We analyzed interview and observational data for internal and external factors that shaped their implementation. Internal factors included opportunities for novel teaching and making connections to existing curriculum, activities, and/or practical knowledge. External factors included the presence, or absence, of building supports, inadequate class time, non-core class status, and COVID-19 policies. Internal factors generally supported teachers’ enactment of the materials, whereas external factors that could not be negotiated caused barriers to enactment. Our implications for this work include the importance of teacher support for new curriculum implementation.more » « less

The purpose of this research study is to understand teacher experiences throughout their second year of engagement in the Virginia Tech Partnering with Educators and Engineers in Rural Schools partnership. This partnership is an assets-based community partnership in a rural environment between middle school teachers, regional industry, and university affiliates that is focused on implementing recurrent, hands-on, culturally relevant engineering activities for middle school students. This qualitative study uses constant comparative methodology informed by grounded theory on teacher interviews to capture both teacher experiences in the partnership as well as teacher-identified assets in their classrooms and school communities. Using the sensitizing concepts of pedagogical content knowledge, self-efficacy, and the Interconnected Model of Teacher Growth, this study found that while teachers experienced the program differently depending on their contextual setting of their schools, all teachers expressed shifts in their recognition of and value placed on community assets. Findings also suggest that teachers greatly value involving industry and university partners in the classroom to highlight the applications of engineering in their communities and support a reimagination of engineering conceptions and careers for both students and teachers. Teachers reported that the hands-on, team-based, culturally relevant engineering activities engaged learners and showcased individual strengths in ways they otherwise do not see exhibited in their traditional curriculum. The partnership ultimately allowed teachers to identify how assets in schools’ rural communities, beyond those previously identified within their schools, could aid them in further developing and implementing engineering activities. With teachers serving as role models for students, it is important to support teachers’ reimagination of engineering conceptions and integration into the classroom to ultimately increase students’ engineering engagement. Our findings highlight the value of community-based approaches in supporting engineering integration in the classroom and describe the assets that teachers note as being the most significant in their community.more » « less
