I explore students' discourses in small groups working on mathematical problems using GeoGebra, focusing on the Cartesian connection between algebra and geometry. Specifically, the interest lies in what is internally persuasive for students in upper-secondary school (11th grade) with histories of low attainment. Three problem-solving episodes are…

Developing a software environment to enhance 3D geometric proficiency demands the consideration of theoretical views of the learning process. Simultaneously, this effort requires taking into account the range of tools that technology offers, as well as their limitations. In this paper, we report on the design of Virtual Spaces 1.0 software, a…

Encourages the use of the microcomputer to teach probability theory and concepts. Presents an instructional sequence and provides 10 activities, three of which have short programs listed. (JM)

In early 2004, Cabrilog released version "II plus" of their interactive geometry package. According to the author, "Cabri Geometry II plus" is clearly a much more useful package than the earlier version. However, unlike other sophisticated applications packages, the designers have avoided creating so many options that secondary students lose their…

Investigated the effects of email conversations between teachers and students on learning graphing in ninth grade classrooms. Compares students who used software with students who used software with email, and discusses results which showed email use led to better performance on graph interpretation and construction and on students' ability to…

Relates one secondary geometry teacher's experiences learning and using the computer program "Geometer's Sketchpad." The article describes the program and provides examples of ways this teacher uses it in combination with more traditional teaching tools. (SM)

The purpose of this project is to help teachers of mathematics get started using the computer to aid the teaching and learning of many mathematical concepts in a meaningful way. To this end, commercially available software packages are described which are versatile, cost effective, and easy to use. A review and several lessons, including homework…

Argues that students should have dynamic perceptual experience with the concepts central to circular functions. Includes a computer program, designed for Apple II, to provide such experience. (PK)

Describes a study at a secondary school in Glasgow (Scotland) in which teacher-pupil and pupil-pupil pairs of users collaboratively used eight commercial educational software programs, four related to mathematics and four to English language teaching, to determine whether software style affects patterns of interactions. (23 references) (LRW)

Describes and analyzes a study of the influence of computers on pupils ages 12-14 in Spain. Four fields of action are defined: (1) research; (2) teacher training; (3) student and teacher activities; and (4) the development of teaching materials. An example of the curricular development of units for mathematics is included. (Contains 21…

This article first explains a "number trick" using algebra and then extends the ideas by use of a computer program. (PK)

Discusses computer methods for finding roots of polynomials. The program provided finds rational roots and prints the roots as rational numbers. (PK)

Analyzes the construction of mathematical concepts and techniques developed by high school algebra students in computer-assisted instruction; examines learning styles of the most inventive students; and discusses the use of student-generated mathematical techniques in the development of new software intended to cultivate mathematical inventiveness…

Weaknesses in educational software currently available in the domain of mathematics are discussed. A technique that was used for the design and production of mathematics software aimed at improving problem-solving skills which combines sound pedagogy and innovative programming is presented. To illustrate the design portion of this technique, a…

Presents a program written in USCD Pascal that simulates a system routine. Illustrates standard and user defined boolean and string functions and string procedures. Details the processing operations. (CW)
