Randy Philipp

Randy Philipp serves as Professor in the School of Teacher Education at San Diego State University (SDSU), where he teaches mathematics methods courses for elementary and secondary teacher preparation programs. His contact information includes email rphilipp@sdsu.edu and office phone 619-594-1371 in North Education Building 99.

His academic background includes:

• Ph.D. in Mathematics Education (Minors: Mathematics and Educational Psychology) from University of Wisconsin-Madison
• M.S. and B.A. in Mathematics from California State University-Northridge
• Single Subject Teaching Credential in Mathematics from California State University-Northridge

Professor Philipp's research examines how students conceptualize mathematical abstractions through real-world contexts, particularly focusing on integer reasoning in financial scenarios and teacher noticing of children's cognitive processes. His work bridges historical perspectives of mathematical development with contemporary classroom practice, emphasizing diagnostic approaches to mathematical difficulties.

Through his graduate seminars and methods courses, he prepares educators to implement learning trajectories and responsive teaching strategies. His publication record demonstrates consistent contributions to mathematics education literature, with recent work appearing in top-tier journals including the Journal for Research in Mathematics Education and Educational Studies in Mathematics.

Professor Philipp's professional journey—from inner-city teaching to Peace Corps service in Liberia to doctoral studies under Tom Carpenter—shapes his commitment to contextualized, student-centered mathematics instruction that addresses diverse learning needs.
