About
Nathaniel Ostashewski is a leading researcher in online teacher professional development (oTPD), with a focus on constructionist learning theory. His work explores how digital environments can support just-in-time, ongoing professional growth for educators, particularly through hands-on, project-based activities. His most cited paper, "Applying constructionist principles to online teacher professional development" (2011, 48 citations), examines the first iteration of a constructionist oTPD courselet, demonstrating how teachers can engage in meaningful, active learning online. A second influential study, "Constructionist principles in online teacher professional development: Robotics and hands-on activities in the Classroom" (2010, 8 citations), extends this work by integrating robotics and tangible learning tasks into virtual TPD. Ostashewski’s research is notable for its use of design-based research methodology, iteratively refining oTPD models to improve teacher practice. His contributions have helped shape the field of technology-enhanced professional learning, emphasizing that effective online TPD must be active, social, and grounded in authentic classroom contexts. For students and researchers, Ostashewski’s work offers a compelling model for designing scalable, constructionist professional development that bridges theory and practice in digital learning environments.
