Julia Plummer spent more than a decade teaching children and adults in planetariums and other informal settings as well as extensive experience teaching college-level introductory astronomy and science methods for preservice elementary teachers. Her research interests focus on how children and adults engage in scientific practices in the domain of astronomy. This includes investigating both formal environments, such as classrooms, and informal environments, such as planetariums and museums. She has also investigated the importance of spatial reasoning in the domain. Her research has led to the development of astronomy learning progressions focused on explaining celestial motion phenomena and connecting observations of the current Solar System to its formation model. Dr. Plummer co-authored a middle school astronomy curriculum and collaborated on the development of planetarium programs for children. Dr. Plummer received a combined Ph.D. in Astronomy & Education from the University of Michigan.
Dr. Plummer is currently engaged in several collaborative research projects that involve Penn State graduate students, including:
- My Sky Tonight: Early Childhood Pathways to Astronomy. As Co-PI on this NSF-funded research and development project, Dr. Plummer has led a team of graduate students, early career researchers, and informal science educators in investigating how informal science educators engage preschool-age children in astronomy and how young children engage in the practices of scientific argumentation through informal astronomy experiences. This project is in collaboration with the Astronomical Society of the Pacific, Cal Poly, and UC-Santa Cruz: https://www.astrosociety.org/education/my-sky-tonight/
- ThinkSpace: Thinking Spatially about the Universe: As Co-PI on this NSF-funded research and development project, Dr. Plummer is collaborating with astronomers and astronomy educators at the Harvard-Smithsonian Center for Astrophysics to develop astronomy labs that will support spatial thinking in middle school students. She and her Penn State graduate students are investigating how middle school students who participate in curriculum designed to support their spatial thinking through physical and computer simulated models demonstrate improved indicators of spatial thinking. http://wwtambassadors.org/thinkspace-labs
- Earth and Space Science Partnership: As a senior researcher on this large-scale NSF-funded project, Dr. Plummer leads a team which initially focused on the development of a learning progression for the Solar System and its formation, guided by investigation of a middle school teacher's implementation of targeted curriculum on this topic. Subsequent investigations from this team have begun to investigate methods of supporting middle and high school students' understanding of science practices in astronomy, with a focus on how astronomers use telescopes and other instrumentation to gather data. http://www.essp.psu.edu/
