This section of Crossroads in Mathematics, a guideline for improving introductory postsecondary mathematics courses, outlines the standards for the content of mathematics courses. While mathematical content has traditionally been the focus of curriculum development, this document takes the view that “”knowing mathematics means being able to do mathematics and that problem solving is the heart of doing mathematics. The successful problem solver can view the world from a mathematical perspective.”” The section outlines and describes seven integral content areas of an introductory mathematics course: number sense, symbolism and algebra, geometry, function, discrete mathematics, probability and statistics, and deductive proof. The document will benefit educators and administrators alike to enhance the content of any mathematics course and help students understand the meaning and use of mathematics beyond rote memorization.
