Jon R. Star
Professor of Education
Jon Star is an educational psychologist who studies children's learning of mathematics in middle and high school, particularly algebra. Star's current research explores the development of flexibility in mathematical problem solving, with flexibility defined as knowledge of multiple strategies for solving mathematics problems and the ability to adaptively choose among known strategies on a particular problem. Star also investigates instructional and curricular interventions that may promote the development of mathematical understanding. Star's most recent work is supported by the National Science Foundation. In addition, Star is interested in the preservice preparation of middle and secondary mathematics teachers. Prior to his graduate studies, Star spent six years teaching middle and high school mathematics.

Collaborative Research: Investigating Gender Differences in Digital Learning Games with Educational Data Mining (2022-2025)
National Science Foundation
Professor Star will serve as the principal investigator on this project. He will supervise all aspects of the proposed work, in collaboration with the PI at Carnegie Mellon University. In particular, he will vet the mathematics curriculum materials and content, suggest appropriate pedagogy to be incorporated into the mathematics games, and design new middle school mathematics material. Jon will also provide input to the experimental design and help write research papers on the results of studies.
