David Phelps is currently pursuing his Ph.D. in the Learning Sciences at the University of Washington. As an educational researcher he studies the ways in which young students develop mathematical modeling practices and learn to reason across difference as they collaboratively puzzle through simple yet deep board games. As a game designer he creates original games that students of all ages find easy to learn, quick to play, yet challenging to master. Taken together, he designs game-based learning environments that invite young students to have fun playing with mathematical and philosophical concepts. David has been fortunate enough to present his research findings and game designs with colleagues in such venues as Interaction Design and Children, Philosophy for Children, Simulation and Gaming, Philosophy of Education Society, National Art Education Association and NASAGA.
