The ACLIPSE project leveraged NOAA assets including the NOAA-funded Ocean Sciences Sequence for Grades 6–8: The Ocean–Atmosphere Connection and Climate Change, data from NOAA-supported ocean, estuarine and atmospheric observing networks, and NOAA-affiliated scientists. ACLIPSE developed strategies for incorporating real-time ocean observing data into climate and ocean science education; designed and implemented an undergraduate curriculum in climate science for pre-service (student) teachers at multiple universities (http://mare.lawrencehallofscience.org/college-courses/ACLIPSE); offered a variety of workshops for teachers and educators across the country and at National Estuarine Research Reserves (NERRs); and developed materials specifically designed to provide professional learning and instructional materials for middle and high school teachers to use with their students and other learners (http://mare.lawrencehallofscience.org/curriculum/climate-data-aclipse-a…). The professional learning workshops for local teachers and NERR Education Coordinators and research staff (i.e., System Wide Monitoring Program (SWMP) Technicians) were located at five NERR sites representing different regions of the US, including the Pacific Northwest (Kachemak Bay NERR, Alaska and Padilla Bay NERR, WA), central West Coast (San Francisco NERR, CA), Southeast (GTM NERR, FL), and Northeast/Mid-Atlantic (Jacques Cousteau NERR, NJ). Resources and instructional materials focused on climate and ocean acidification were provided to all participants for learning about and teaching these important and relevant content areas, and as the context for teaching about and applying current teaching and learning research. Emphasis was placed on helping the teacher audiences to becoming more expert on how to use NOAA monitoring data in the classroom in authentic and engaging ways to build teacher and student data skills. NERR educators and their local in-service teachers were provided with professional learning opportunities and a collection of activities providing online data, place-based, locally relevant observing data, NGSS teaching and learning pedagogy, and climate change topics. The project built capacity of formal and informal science educators by providing (1) opportunities to become knowledgeable about global environmental change and real-time data; (2) exposure to place-based connections with the ocean through technological observing systems; and (3) materials and expertise to apply their learning to teaching practice in a long-term, sustainable manner. ACLIPSE instructional materials are based on the principle that real-time environmental data is a valuable tool for providing students with opportunities for self-directed exploration of the natural world. Students engaging in these activities gain a deeper understanding of carbon cycling, ocean acidification, and other phenomena related to climate change. These activities were designed with the three-dimensional approach to teaching in mind (e.g. NGSS-designed), and also use a data literacy framework to build educators and their learners’ skills in using data visualizations. The materials for informal educators and grades 6-8 teachers can also be accessed from the NOAA Education site, Classroom- Ready Data Resources, Climate & Data ACLIPSE Activities at https://www.noaa.gov/education/resource-collections/data/classroom-ready. Partners in the project included Rutgers University, Padilla Bay National Estuarine Research Reserve, Florida State University, California State University East Bay, Louisiana State University, and multiple NERR sites and Education Coordinators across the country and their local secondary teachers.
