Rachel E. Scherr (Periscope creator and director) considers Periscope to be one of her most significant accomplishments. Periscope embodies the value she places on understanding and appreciating the complexity of human interaction in physics learning environments. Scherr is responsible for the vision and mission of Periscope and creates all of its content. Scherr is a senior physics education researcher with a 20-year history studying the teaching and learning of physics. She obtained her PhD in physics from the University of Washington in 2001 for investigations of student understanding of special relativity. She has authored dozens of publications, supervised five doctoral dissertations, and served as principal investigator on numerous awards from the National Science Foundation. She was made a Fellow of the American Physical Society for “foundational research into energy learning and representations, application of video analysis methods to study physics classrooms, and physics education research community leadership.”
Renee Michelle Goertzen (Periscope co-founder) contributed substantially to the first release of Periscope. She is now the Senior Program Manager at the American Physical Society and has worked on a variety of programs to improve education and diversity in physics nationally, including the Physics Teacher Education Coalition and the Conferences for Undergraduate Women in Physics. Goertzen earned a PhD in Physics from the University of Maryland, College Park. Her research interests are professional development for physics instructors and developing community among physics learners and instructors.
Sam McKagan (Periscope website director) led the design and development of the Periscope website. She is also the director of Periscope’s parent site, PhysPort, and is the design and development director of the Living Physics Portal. She is an expert on physics faculty needs around teaching and on user-centered design of web resources for physics educators.
Sandy Martinuk (Periscope website designer) conducted usability research and designed the Periscope website. He is an expert in user experience design for physics education resources, and has done user experience design for several STEM education websites, including PhysPort, PhET Interactive Simulations, and the Living Physics Portal.
Lyle Barbato (Periscope website developer) built the Periscope website. He is the lead developer for PhysPort and ComPADRE.
Adrian Madsen (Periscope website researcher) conducted usability research for the design of the Periscope website. She is the assistant director of PhysPort and a research scientist for the Living Physics Portal.
Stephanie Chasteen (external evaluator) conducted research on Periscope use and gave feedback on the design process. She has been an external evaluator for over a dozen STEM education projects.
