The research team from the Center for Research on Lifelong STEM Learning at Oregon State University (Martin Storksdieck, Kelly Riedinger, and Brianna Keys), in collaboration with researchers from TERC, will partner with the Gulf of Maine Research Institute on a research in service to practice project funded by NSF’s Advancing Informal STEM Learning program. This project will examine the impact of a 12-year statewide science field trip program called LabVenture. This hands-on program in discovery and inquiry brings middle school students and teachers from across the State of Maine to the Gulf of Maine Research Institute (GMRI) in Portland, Maine to become fully immersed in explorations into the complexities of local marine science ecosystems. These intensive field trip experiences are led by informal educators and facilitated entirely within informal contexts at GMRI. Approximately 70% of all fifth and sixth grade students in Maine participate in the program each year, and more than 120,000 students have attended since the program’s inception in 2005. Unfortunately, little is known to date on how the program has influenced practice and learning ecosystems within formal, informal, and community contexts. As such, this research in service to practice project will employ an innovative research approach to understand and advance knowledge on the short and long-term impacts of the program within different contexts. If proven effective, the LabVenture program will elucidate the potential benefits of a large-scale field trip program implemented systemically across a community over time and serve as a reputable model for statewide adoption of similar programs seeking innovative strategies to connect formal and informal science learning to achieve notable positive shifts in their local, statewide, or regional STEM learning ecosystems.
