Using CAS to Develop Precalculus Concepts in a US Curriculum
Abstract:
Computer Algebra Systems can be used as a pedagogical tool to help high school students learn mathematical concepts. With a CAS, equivalence transformations help to solve nth root and exponential equations as well as to derive inverse functions. Making conjectures from patterns produced on a CAS help in investigating the binomial theorem, exploring the division and remainder theorems, and factoring sums and differences of powers. CAS contributes to the use of multiple representations (tables, graphs, and the symbol manipulator) to provide various ways to consider the definition of even and odd functions. Four years of anecdotal evidence in a US high school suggests that appropriate use of a CAS enhances students' understanding and performance.
