While our world consistently presents complicated, interdisciplinary problems with STEM foundations, most pre-university curricula do not encourage drawing on multidisciplinary knowledge in the sciences and engineering to create solutions. We developed an instructional approach, Iterative Science and Engineering (ISE), that cycles through scientific investigation and engineering design and culminates in constructing a solution to a local environmental challenge. Next, we created, revised, and evaluated a six-week ISE curricular program, Invasive Insects, culminating in 6th–9th-grade students building traps to mitigate local invasive insect populations. Over three Design-Based Research (DBR) cycles, we gathered and analyzed identical pre and post-test data from 554 adolescents to address the research question: what three-dimensional (3D) science and engineering knowledge do adolescents demonstrate over three DBR cycles associated with a curricular program following the Iterative Science and Engineering instructional approach? Results document students’ significant statistical improvements, with differential outcomes in different cycles. For example, most students demonstrated significant learning of 3D science and engineering argument construction in all cycles—still, students only significantly improved engineering design when they performed guided reflection on their designs and physically built a second trap. Our results suggest that the development, refinement, and empirical evaluation of an ISE curricular program led to students’ design, building, evaluation, and sharing of their learning of mitigating local invasive insect populations. To address complex, interdisciplinary challenges, we must provide opportunities for fluid and iterative STEM learning through scientific investigation and engineering design cycles.

Usable STEM knowledge for tomorrow's STEM problems
Usable STEM knowledge for tomorrow's STEM problems More universities and education programs need more STEM knowledge in formal and informal settings to guide learners in applying STEM learning to the creation of solutions. To address this challenge, Nancy Butler Songer, the dean of the College of Education at the University of Utah designed a learning approach, Solutioning, that guides youth to deepen science content through science and engineering practices. Creating a six-week curricular program, the learning approach provided opportunities for students to use engineering design to create and provide feedback on a trap design that would attract a local invasive insect that was harmful to their community. Research was conducted on studies to provide empirical evidence on student STEM knowledge and learning and their ability to define science and engineering. Research results indicate that even elementary-age students demonstrate significant improvement in their understanding of STEM arguments as evaluated with a pre-post assessment before and after implementing a six-week solutioning curricular program.

Emerald Insight (Ed.)Abstract Purpose The authors designed a science and engineering curricular program that includes design features that promote student interest and motivation and examined teachers' and students' views on meaningfulness, motivation and interest. Design/methodology/approach The research approach consisted of mixed methods, including content analyses and descriptive statistics. Findings The curricular program successfully included all four of the US National Academies of Sciences' design features for promoting interest and motivation through scientific investigation and engineering design. During interviews, teachers and students expressed evidence of design features associated with interest and motivation. After experiencing the program, more than 60% of all students scored high on all four science and engineering meaningfulness and interest survey items. Originality/value A curricular program that extends science learning through the engineered design of solutions is an innovative approach to foster both conceptual knowledge development and interest and motivation in science and engineering.more » « less

null (Ed.)Access to enriching science programs is not equitable, with students from affluent districts having more opportunities to develop their science, technology, engineering, and mathematics (STEM) skills than students from underserved districts. The Building Unique Inventions to Launch Discovery, Engagement, and Reasoning in STEM (BUILDERS) program was started in 2017 with support from the National Science Foundation’s ITEST program to provide students from the Alabama Black Belt with STEM opportunities to which they would otherwise have no access. This project-based learning (PBL) program uses the concept of a makerspace to allow students to explore how science and technology can be used to solve the problems that affect their own communities. During an intensive, 3-week summer experience (the BUILDERS Academy), teams of students enthusiastically use the makerspace to design, build, and test prototypes of technology-based solutions to their community problems. During this immersive PBL process, they acquire and apply STEM concepts, learn about STEM careers, and acquire valuable 21st century skills. An extension of the summer Academy into the academic year was only moderately successful, highlighting the need to make extra-curricular STEM interventions available to underserved students in order to increase equitable access to practical and enriching educational experiences in STEM.more » « less

Abstract Current research underscores that there are only a few evidence-based programs that teach STEM (science, technology, engineering, and mathematics) as part of their curriculum, especially for autistic students. Even fewer programs focus on engineering and design learning. Hence, we developed an informal afterschool maker program to develop autistic and non-autistic students’ interests in engineering to understand their experiences learning STEM concepts and values while applying the engineering mindset to develop projects. This qualitative study aimed to explore and understand students’ experiences participating in STEM activities in the maker club. We interviewed twenty-six students (seventeen autistic and nine non-autistic), nine teachers, and thirteen parents representing diverse cultural and socio-economic backgrounds across three public middle schools in a large urban metropolitan city between 2018 and 2019. Our thematic analysis yielded four themes:(1) active participation in STEM; (2) curiosity about STEM topics, concepts, and practices, (3) capacity-building to engage in STEM learning; and 4) understanding of the importance of STEM education in daily life.The results of this study enabled us to understand that students were deeply engaged with the content and curriculum of our program, expanded their knowledge base about scientific concepts, used engineering-specific scientific terminologies, and engaged with the engineering design process to conceptualize, test, improvise, and problem-solve. Furthermore, this afterschool engineering education program created a safe, nurturing, and stimulating environment for students to build engineering readiness skills.more » « less
