This chapter discusses the context in which the teaching and learning of mathematics occurs and the role of the teacher in that greater context. It explores the role of parents in the educational process. Mathematics can be a social activity—research shows that students learn math concepts best when they talk to other students about what they’re doing. Generally, the mathematics department has a chair that is responsible for leading the process, running meetings, and overseeing the implementation of programs. It is extremely important that each member of a department actively contributes to the improvement of the program. Part of the responsibility of a mathematics teacher is to identify problems with the program—weaknesses of the curriculum, inappropriate or inadequate content of the texts, or lack of classroom materials—and work toward the improvement of that area. A professional development specialist conducted a workshop for secondary and middle school mathematics teachers in a local school district.
