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. 

Engineering education, with its focus on design and problem solving, has been shown to be fertile ground for encouraging students’ further development of their fundamental math and science skills in a way that they find relevant and engaging, and for promoting interest in STEM more broadly. To capitalize on these positive aspects of the engineering context, researchers developed, implemented, and studied a three-year engineering curriculum for grades 6 – 8 that utilizes the engineering design process and problem-based learning. In this semester-long elective course, students work through a series of design challenges within a given context (a carnival, airplanes and flight, and robotics, respectively, for 6th, 7th and 8th grades) and learn engineering content as well as practice fundamental math and science skills. This curriculum was developed and researched as part of an earlier project; in that work, course participation was linked with increased academic achievement on state-wide math and science assessments as well as heightened cognitive and behavioral engagement in STEM and science interest [1]. The current work seeks to replicate the findings of this earlier study in a different and larger school district while a) expanding the research foci to include teacher training and teachers’ pedagogical content knowledge and b) refining the curriculum materials including the teacher website and support materials. In this paper, we present the research strand focusing on the impact of the course on students’ attitudinal factors including engagement, science interest, and science and math anxiety. These factors were measured in each semester-long course using a pre-post survey design. Survey items are primarily from validated instruments and are similar to those used in prior research on this curriculum and its impact on students; prior research demonstrated good reliability, with alpha values ranging from 0.84 to 0.91 for each construct [1]. We compare students’ levels of engagement, science interest, and math and science anxiety at the pre and post time points to understand whether and how participating in the course influences their standing on these variables. . Open-ended survey items were used as a supplementary data source. The preliminary results from the first year of implementation (2022-2023 academic year) suggest that similar to the original study, there is an increase across some of the student constructs, including student engagement. This finding was also supported by engineering teachers’ input about student engagement in the classroom. As the study progresses into its planned 2nd and 3rd years of curriculum implementation, we will be able to further discern the extent to which multiple years of course enrollment might differentially impact the attitudinal factors of interest (i.e., dosage effects). 

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. 

ABSTRACT Engineering has emerged as a promising context for STEM integration in K‐12 schools. In the previous decade, the field has seen an increase in curricular resources and pedagogical approaches that invite students to utilize mathematics and science as they engage in engineering practices. This Innovation to Practice paper highlights one effort to meaningfully integrate mathematics and science through engineering in middle school classrooms. The STEM‐ID engineering course sequence consists of three 18‐week middle school engineering courses. Each of the 6th, 7th, and 8th grade courses integrate science and math with engineering design, enabling students to explore and practice foundational math and science skills in a low‐risk, non‐high‐stakes‐tested environment. This Innovation to Practice paper provides illustrative examples of STEM‐integration through the STEM‐ID curricula, focusing on four key areas: data analysis, measurement, experimental design, and force and motion concepts. Drawing on our project's implementation data, we highlight illustrative examples of STEM integration, in practice, and lessons learned by educators and researchers involved in the project. 

Biologically inspired design (BID) has gained attention in undergraduate and graduate engineering programs throughout the United States, and more post-secondary institutions are beginning to implement it into their engineering curriculum [1], [2]. However, little has been done to introduce BID concepts more formally into the K-12 curriculum. Consequently, a research study funded by the National Science Foundation focused on developing a BID integrated engineering curriculum for high school students. The curriculum is designed to integrate BID into the engineering design process (EDP) by leveraging analogical design tools that facilitate a transfer of biological strategies to design challenges. This enables students to understand both the engineering problem and the biological system that could be used to inspire design solutions. In this paper, we describe students’ application of BID integration in the engineering design process and their experiences utilizing BID as they solve design challenges. The curriculum was pilot tested in two 9th grade engineering classrooms across two schools during Spring 2022. Data was collected from four groups of students (n=12) enrolled in the engineering courses across two schools. The study includes classroom observations, student artifacts, and student focus groups. We utilized qualitative content analysis, a descriptive approach to analyzing student data [3], [4], to uncover the meaning and presence of text, messages, images, and transcriptions of dialogues [4]. In this study, we aim to capture the evidence of students’ experiences and engagement with BID concepts. The preliminarily findings illustrate that student groups enjoyed BID activities presented in the curriculum as they promoted students’ exploration of biological systems. BID integration allowed students to view nature differently, which some students indicated they had not previously employed for their design solutions. Although some students mentioned BID activities that helped them during the brainstorming phase of the design process, they were unable to explain BID integration in their final design solutions, unless prompted by the teacher. Furthermore, across the student groups, students indicated that prototype and test was the most engaging stage of the EDP since during this stage they were able to test their designs. This research is novel in its focus on understanding high school students’ experiences with the integration of BID in engineering and has important implications for diversifying engineering in K-12 education. 

This innovative practice work in progress paper presents the Biologically Inspired Design for Engineering Education (BTRDEE) project, to create socially relevant, accessible, highly-contextualized biologically inspired design experiences that can be disseminated to high school audiences engineering audiences in Georgia and nationally. Curriculum units arc 6-10 weeks in duration and will meet many standards for high school engineering courses in Georgia. There will be three curriculum units (one for each engineering course in the 3-course pathway), each building skills in engineering design and specific skills for BID. Currently in its second year, BIRDEE has developed its first unit of curriculum and has hosted its first professional development with 4 pilot teachers in the summer of 2020. The BIRDEE curriculum situates challenges within socially relevant contexts and provides cutting-edge biological scenarios to ignite creative and humanistic engineering experiences to 1) drive greaterengagement in engineering, particularly among women, 2) improve student engineering skills, especially problem definition and ideation skills, and 3) increase students awareness of the connection and impacts between the engineered and living worlds. This paper describes the motivation for the BIRDEE project, the learning goals for the curriculum, and a description of the first unit. We provide reflections and feedback from teacher work and focus groups during our summer professional development and highlight the challenges associated with building BID competency across biology and engineering to equip teachers with the skills they need to teach the BIRDEE units. These lessons can be applied to teaching BID more broadly, as its multidisciplinary nature creates challenges (and opportunities) for teaching and learning engineering design. 

This innovative practice work in progress paper presents Biologically inspired design (BID) to transfer design principles identified in nature to human-centered design problems. The Biologically Inspired Design for Engineering Education (BIRDEE) program uses biologically inspired design to teach high school engineering in a way that uniquely engages students in the natural world. For high school students, identifying natural systems’ analogues for human design problems can be challenging. Furthermore, it is often the case that students focus on and transfer superficial structures, rather than underlying design principles. Based on the Structure-Behavior-Function (SBF) design ontology, we developed a modified cognitive scaffold called Structure- Function-Mechanism (SFM) to assist students and teachers with identifying functionally similar biological analogies and identifying and transferring design principles. In this paper we describe SFM and its importance in BID and our observations from teaching SFM to high school teachers during a multi-week professional development workshop in the summer of 2020. Based on teachers’ work artifacts, transcriptions of discussions, and focus groups, we highlight the challenges of teaching SFM and our plans to scaffold this important concept for students and teachers alike. 

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
