Phil Vahey
Phil Vahey, Ph.D. is a senior research scientist with SRI International's Center for Technology in Learning (CTL). Vahey's research examines the design of technologies and learning activities that enhance learning of conceptually difficult mathematics.
His recent research has focused on the use of computer-based representations for making the mathematics of change accessible to a diverse student population, including English language learners. He is also researching how students can increase their data literacy through cross-disciplinary learning activities. Vahey leads CTL's SunBay Digital Mathematics Project, the Thinking With Data initiative, and the Speech Technology Enhanced Assessment of Mathematics Modeling (STEAM) project. He is a senior contributor to other projects, including the SimCalc project, the Evaluation of Early Elementary Mathematics Curricula project, and CTL’s commercial efforts.
Prior to joining SRI, Vahey was a research assistant a t the University of Calfornia, Berkeley and an engineering manager at FileMaker, Inc. (was Claris Corporation).
Vahey has a B.S. in mathematics and computer science from McGill University, and an M.A. from UC Berkeley. His Ph.D. in education is also from UC Berkeley.
