The United Nations Sustainable Development Goals (UN SDGs) are the focus for a Research Experience for Teachers (RET) Site in Engineering at X University. The relevant and meaningful contexts of the SDGs allow middle and high school teachers and their students to easily make connections between research in a university lab setting to Science, Technology, Engineering, and Math (STEM) concepts in their classroom. Lesson plans inspired by the UN SDGs research experience were developed as an “integrated STEM” problem solving activity by each of the RET teachers. Ten (10) teachers comprising of both pre-service and in-service middle or high school teachers have participated in each cohort over the two years of the NSF RET grant thus far. Six weeks of authentic summer research takes place in 5 different faculty labs at X University under the mentorship of faculty and their graduate students or postdoc. Examples of the research projects include “Photocatalysis for Clean Energy and Environment,” “Genetically Engineering Plasmid DNA molecules to address Tuberculosis Antibiotic Resistance,” and “New Water-Based Technology for Plastic Recycling.” RET participants also attend a weekly coffee session to help guide the teachers through the research process and a weekly ½-day professional development (PD) session to translate the research experience into a classroom lesson plan that aligns to state standards, as well as evidence-backed curriculum design and teaching strategies. Teacher cohort building and community is fostered through group lunches and additional activities (e.g., coordinated lab visits, behind the scenes tour of a local science museum, and industry panel). For evaluation of the RET program, pre/post-surveys measured the teacher’s self-reported ability, confidence, understanding, and frequency of use of the Engineering Design Process (EDP), Integrated STEM, and the UN Sustainable Development Goals. Formative assessment was conducted throughout the summer on various aspects of the RET through surveys and regular check-ins with the teachers. At the end of the summer, focus groups were conducted by an external evaluator for both the teacher participants and the research mentors. Both teachers and mentors declared the program was well planned and executed. The teachers developed close bonds and connections, learned a lot from each other, had meaningful research experiences, and developed a sense of community. The research mentors reported that the teachers provided useful research contributions, were enthusiastic about the research, had genuine lab experiences, developed professional skills, and built good community connections. Areas for improvement included clear expectations for everyone, reducing steep learning curves, and consistency of mentoring across the labs. The RET program continues into the academic year with occasional meetings to report on the implementation of their research-inspired lesson plan in their classroom. The RET participants share that they are bringing in the “real world” relevance to their students with an integrated STEM lens (e.g., climate change and UN SDGs) and that they refer back to their own lab experiences (e.g., importance of measuring chemicals accurately). The research experience has made several positive impacts on the teacher participants that also benefit their students.
