Abstract: | Dynamic computer environments can facilitate students' active participation in the construction of mathematical concepts and
techniques—a long-standing goal among educational reformers. This paper analyzes techniques developed by students in an open-ended
computer activity, examines learning styles of inventive students, and discusses use of student-generated mathematical techniques
in developing new software to (1) cultivate mathematical inventiveness in more students and (2) encourage students to relate
their own techniques to more general mathematical ideas. New software was designed to provide an informal, interactive introduction
to functions and related algebraic ideas. A fundamentally constructivist approach was supplemented with coaching available
upon student request. Each type of function was targeted with a sequence of challenges, hints to support the challenges, and
games for synthesis and application. Students combined algebraic techniques to construct functions and manipulated the functions
to cause specific behaviors in their graphs. The software succeeded in accommodating diverse student learning styles, initiating
students into use of a wider variety of techniques, and inducing students to take an interactive approach to constructing
mathematical knowledge.
