Presents the results of an investigation into how pre-service teachers with low-level mathematics qualifications do mathematics when using hand-held, sophisticated mathematics technology as a tool. Results indicate that students were able to master the technical aspects of the TI-92, ask relevant questions and engage in mathematical discussion,…

Describes how the introduction of the TI-92 transformed a traditional first semester linear algebra course into a matrix-oriented course that emphasized conceptual understanding, relevant applications, and numerical issues. Indicates an increase in students' overall performance as they found the calculator very useful, believed it helped them…

Presents examples to illustrate that iteration and recursion are useful pedagogical tools that can be used in many areas of mathematics, make models traditionally taught in upper levels accessible in grades 9-14, and provide alternative problem solving approaches less dependent upon ready-made formulas.

Focuses on two teachers who had made no use of DERIVE with their classes but who agreed to make regular use of DERIVE with one of their classes over the course of one year. Presents teachers' accounts of what they did. Discusses time issues in using DERIVE, the use of materials, pressures on teachers that influence their use of DERIVE, and the…

Technology offers the opportunity to study larger, more difficult group structures and perform tedious computations quickly while maintaining the focus on concepts over calculations. Explores several technology options available to the instructor as well as sample assignments and class explorations that effectively integrate technology within the…

Describes a mini-experiment on how the TI-92 might fit into normal classroom learning and considers students' initial reactions to the calculator. (Author/ASK)

Provides experiences of teaching students who had the use of a TI-92 for the semester, both in and out of class, with a greater emphasis on modeling and qualitative graphical methods and decreased emphasis on explicit solution techniques. Indicates that the TI-92 proved to be an invaluable tool for this course. (Author/ASK)

Provides evidence of differences in students' ability to solve problems with and without a computer algebra system. Indicates that almost without exception, the TI-92 students were more successful at symbolically solving problems than comparison students. Observes improved performance on all three levels of problems: (1) directive computational;…

Describes a teaching experiment in which spreadsheets and computer algebra systems were used to teach a low-level college consumer mathematics course. Students were successful in using different types of functions to solve a variety of problems drawn from real-world situations. Provides an existence proof that computer algebra systems can assist…
