معرفی
Dr. John Opfer is a Professor in the Department of Developmental Psychology at The Ohio State University. His research focuses on conceptual development, numerical cognition, and education, particularly how children and adults develop quantitative reasoning skills. He holds a PhD from the University of Michigan (2000) and a BA from The George Washington University (1995).
Key areas of expertise include numerical estimation, analogical reasoning, and the cognitive foundations of mathematical learning. His work bridges developmental psychology, cognitive science, and education, often exploring cross-cultural differences in arithmetic proficiency and the role of language in learning.
- Awards: Huber Faculty Fellowship (2023), APS Fellow (2010), IES Learning Acceleration Challenge Finalist (2022).
- Recent Research Trends: Focus on number-line estimation methodologies, developmental reversals in numerical cognition, and the cognitive mechanisms underlying proportional reasoning.
- Grants and Collaborations: Active in federally funded projects investigating educational strategies and cross-cultural comparisons in math learning.
His lab examines how representational shifts in numerical understanding influence learning trajectories, with implications for educational interventions and cognitive development theories.
