Randall I. Charles, Ph.D., is Professor Emeritus in the Department of Mathematics and Computer
Science at San Jose State University, San Jose, California. He began his career as a high school
mathematics teacher, and he was a mathematics supervisor for fi ve years. Dr. Charles has been a
member of several NCTM committees and is the former Vice President of the National Council of
Supervisors of Mathematics (NCSM). Much of his writing and research has been in the area of problem
solving. He has authored more than 75 mathematics textbooks for kindergarten through college.
The Role of Problem Solving
in High School Mathematics
Problem solving has been the focus of a substantial number of research
studies over the past thirty years. It is well beyond the scope of this paper to
even attempt to summarize this body of research. Those interested in
significantly broader reviews of research related to problem solving should
see Schoenfeld (1985), Charles & Silver (1988), and Lesh & Zawojewski (2007).
This paper focuses on the most recent research related to problem solving that
has a direct impact on the way mathematics is taught every day in secondary
mathematics classrooms.
