Reports on a study replicating and extending a previous study examining the effects of the TI-92 graphics calculator and calculus instruction on students' success in calculus. Finds that students using a TI-92 had significantly better performance on the final exam and overall course grade than students using other calculators, and student-centered…

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. (Author/MM)

Presents a portfolio of examples that illustrate how TI-92 technology has been used to support an undergraduate engineering mathematics course by changing it from student-passive to student-active. The instant feedback and variety of possible representations enables a concepts- and applications-driven interactive teaching approach which has led to…

Addresses the impact of algebraic calculators on mathematics education. Shows how teaching with technology can lead to more efficient teaching and learning, more student-centered learning, and increase teacher value. Recommends that technology is fully embraced in order to perform the mathematics, thus freeing time for students to concentrate on…

Reports the results of a qualitative, classroom-based study on the interactions between the role, knowledge, and beliefs of the teacher; the mathematical tasks; and the patterns of graphing calculator use by a group of pre-calculus students. Describes the development of a set of norms that governed the ways in which the tool was used in the…

Presents an algorithm to compute the critical path in a graph representing a project evaluation research task. Once the algorithm is executed, the last matrix obtained permits the visualization of some important information which leads to the determination of the weight of the critical path. (Author/MM)

Discusses various mathematics topics and focuses on three questions: (1) "What is mathematics?"; (2) "What are good ingredients of teaching/learning mathematics?"; and (3) "What is the role of technology?" (Author/ASK)

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)
