Describes a study examining the effect of hand-held calculators on student achievement in college developmental mathematics classes. Finds no significant differences between control and treatment groups, indicating that students who used calculators scored slightly lower on posttests but achieved higher final course grades as a group than control…

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;…

The authors provide activities for overcoming some fraction misconceptions using calculators specially designed for learners in primary years. The writers advocate use of the calculator as a way to engage children in thinking about mathematics. By engaging with a calculator as part of mathematics learning, children are learning about and using the…

This study took place at Skaneateles High School in Skaneateles, New York in a grade 10 Integrated Math AB course with 52 students in 3 sections using the TI-84 Plus family graphing calculators and the TI-Navigator classroom learning system with a projector and interactive whiteboard. New York State is phasing in a new curriculum that integrates…

For many years, education researchers excited by the potential for digital technologies to transform mathematics teaching and learning have predicted that these technologies would become rapidly integrated into every level of education. However, recent international research shows that technology still plays a marginal role in mathematics…

An understanding of past technological advancements can help educators understand the influence of new technologies in education. Inventions such as the abacus, logarithms, the slide rule, the calculating machine, computers, and electronic calculators have all found their place in mathematics education. While new technologies can be very useful,…

An activity for secondary schools is presented and discussed which may be explored with a programmable calculator. The activity is non-standard and could not be easily explored without the use of a programmable calculator. Related activities are also discussed. Flow charts and programs for different programmable calculators are presented. (MP)

Geometry and a hand-held calculator are used to find a value of pi accurate to five decimal places. (CP)

The authors propose that electronic calculators can be perceived as function generators rather than mere computational aids and can be used to investigate function concepts such as domain, range, composition, inverse, correspondence and so on. (MN)

The increasing availability of computer algebra systems (CAS) for the high school classroom is expected to have a significant effect on how algebra is taught, when it is taught, and the expected learning types. This paper reports on a computer algebra approach to the teaching of algebra to 13-16 year old students in a high school in Melbourne,…

This paper reports on a mathematics course in an Austrian high school that focuses on probability distributions. Students in this course used a TI-92 during math classes, at home for doing exercises, and during math tests. The TI-92 was used as a tool for calculations and illustrations making the concepts of probability distributions easy to…

The purpose of this study was to investigate the effects of the Casio 9850 and the TI-85 graphing calculators on college students' procedural skills and conceptual understanding in two different developmental mathematics courses. The courses used in this study were Elementary Algebra and Intermediate Algebra. Both the non-graphing calculator group…

In this presentation we will investigate the mathematics and physics of a free-falling object, not for the purpose of research to discover some profound physical phenomena, but rather to enhance students' ability to gather, organize, and analyze data using state of the art hand held technology. We will use the TI-83 plus (a sophisticated graphing…

A proposal for teaching how to graph functions is presented on the basis of the teaching theory of didactical situations implemented by the French author Guy Brousseau. The proposal is aimed at students in 12th grade in high school (USA) or in a freshman calculus course. The TI-92 graphic calculator was used as a teaching aid. (Author/ASK)
