1. Extending Engineering Learning Beyond Field Trips

   We worked with local K–6 teachers to develop lesson plans that would connect a 50-minute engineering design challenge, completed during a field trip, to the students’ classroom learning. The result was a model for designing pre-visit classroom activities that develop students’ familiarity with phenomena, tools, and processes that will be used during the field trip and post-visit classroom activities that provide students with opportunities to reflect on some of their field trip experiences. While the field trip activity alone is an exciting and productive learning opportunity, students who complete the full set of classroom and field trip activities participate in a richer experience that engages them in more of the practices of science and engineering and more fully develops the disciplinary core ideas related to engineering and physical science. Each Engineering Exploration module includes four activities: an engineering design activity completed during a field trip to an interactive science museum, accompanied by two preactivities and one post activity done in students’ classroom and facilitated by their elementary school teacher. While each classroom activity was designed to take no more than 50 minutes, many teachers found it valuable to extend each lesson to allow for deeper discussion and engagement with the activities. The classroom experiences presented here are associated with a field trip program in which students iteratively design a craft out of paper and tape that will hover above a “fire” (upward moving column of air) while carrying a “sensor” (washer). The classroom activities surrounding this field trip help students develop conceptual understandings of forces to navigate the engineering design challenge.

2. Engineering Explorations: Connecting K-12 classroom learning and field trip experiences through engineering design

   Harlow, D. (July 2021, 2021 American Society for Engineering Education Conference Proceedings)

   null (Ed.)

   Interactive science centers are in a unique position to provide opportunities for engineering education through K-12 field trip programs. However, field trip programs are often disconnected from students’ classroom learning, and many K-12 teachers lack the engineering education background to make that connection. Engineering Explorations is a 3-year project funded by the National Science Foundation (NSF) program Research in the Formation of Engineers (RFE) (EEC-1824856 and EEC-1824859). The primary goal of this project is to develop and test engineering education modules that link K-12 students’ classroom learning to field trip experiences in an interactive science museum, increasing student learning and extending the field trip experiences. Each Engineering Explorations module consists of one 50-minute field trip program completed at an interactive science center and curriculum for three 50-minute lessons to be implemented by the classroom teacher before (2 lessons) and after (1 lesson) the field trip program. Our paper will present both development and research outcomes.

3. The Purposes of Preservice Teachers' Gestures During One-on-One Algebra Tutoring

   DeJarnette, A. F. (January 2022, Annual meeting program American Educational Research Association)

   Gestures are an integral component of mathematics classroom discourse. There is a need to classify the types of gestures that teachers use according to their purposes towards supporting and extending students’ mathematical thinking. We analyzed 16 algebra tutoring sessions between pre-service teachers (PSTs) and high school students to categorize the PSTs’ gestures. We identified 10 categories of PST gestures that we roughly organized into three supercategories: gestures that facilitate shared attention and communication, gestures that emphasize written visual representations, and gestures that support verbal explanations. A taxonomy of gestures based on their purposes will enable further analyses of teacher gesturing and help preservice and practicing teachers use gestures in more purposeful ways.

4. Partnering to Develop a Coordinated Engineering Education Program Across Schools, Museum Field Trips, and Afterschool Programs

   Harlow, D. (January 2020, Connected science learning)

   Engineering Explorations are curriculum modules that engage children across contexts in learning about science and engineering. We used them to leverage multiple education sectors (K–12 schools, museums, higher education, and afterschool programs) across a community to provide engineering learning experiences for youth, while increasing local teachers’ capacity to deliver high-quality engineering learning opportunities that align with school standards. Focusing on multiple partners that serve youth in the same community provides opportunities for long-term collaborations and programs developed in response to local needs. In a significant shift from earlier sets of standards, the Next Generation Science Standards include engineering design, with the goal of providing students with a foundation “to better engage in and aspire to solve the major societal and environmental challenges they will face in decades ahead” (NGSS Lead States 2013, Appendix I). Including engineering in K–12 standards is a positive step forward in introducing students to engineering; however, K–12 teachers are not prepared to facilitate high-quality engineering activities. Research has consistently shown that elementary teachers are not confident in teaching science, especially physical science, and generally have little knowledge of engineering (Trygstad 2013). K–12 teachers, therefore, will need support. Our goal was to create a program that took advantage of the varied resources across a STEM (science, technology, engineering, and math) education ecosystem to support engineering instruction for youth across multiple contexts, while building the capacity of educators and meeting the needs of each organization. Specifically, we developed mutually reinforcing classroom and field trip activities to improve student learning and a curriculum to improve teacher learning. This challenging task required expertise in school-based standards, engineering education, informal education, teacher professional development, and classroom and museum contexts.

5. Eco-Solutioning: The Design and Evaluation of a Curricular Unit to Foster Students’ Creation of Solutions to Address Local Socio-Scientific Issues

   https://doi.org/10.3389/feduc.2021.642320  

   Songer, Nancy Butler; Ibarrola_Recalde, Guillermo D (March 2021, Frontiers in Education)

   The global pandemic and climate change have led to unprecedented environmental, social, and economic challenges with interdisciplinary STEM foundations. Even as STEM learning has never been more important, very few pre-college programs prepare students to address these challenges by emphasizing socio-scientific issue (SSI) problem solving and the engineering design of solutions to address local phenomena. The paper discusses the design and evaluation of a pre-college, SSI curricular unit where students expand their learning by creating solutions to increase biodiversity within local urban neighborhoods. The learning approach, which we call eco-solutioning, builds from current vision and policy documents in STEM education emphasizing phenomenon-centric instructional materials, science investigations, and engineering design. The paper outlines design principles for creating an eco-solutioning instructional unit that guides young students to: collect and analyze data on local organisms, use an engineering design approach to craft solutions to increase local biodiversity, and present their solutions to local city planners and community members. Two cycles of research studies evaluated student learning using paired t-tests. Results demonstrated significant pre-post learning outcomes in both research cycles. A third research cycle in the form of a summer extension program supported students as they implemented their local solutions. Conclusions highlight design principles for the successful creation of SSI curricular units centered on local environmental issues of interest to students, teachers, and stakeholders.
