Analyzes the mathematics of rotational and translational motion and how one can influence the other in the context of cams and cranks. Describes how the individual components can be brought together to simulate a four-stroke engine and how the engine animates again using the same simple macro. (Author/ASK)

Provides an overview of five earth and space science CD-ROMs and their potential contribution to learning mathematics and science. The software are "Welcome to the Planets"; "GeoMedia 2, Interactive Multimedia CD-ROM on Global Environmental Change"; "Mars Educational Multimedia"; "Redshift Multimedia Astronomy"; and "Expert Astronomer."…

Discusses the impact of technology such as graphing calculators or statistical software packages on statistics instruction and curriculum as it makes teaching some topics unnecessary, makes instruction in some topics better, and allows for the teaching of some topics that have never been taught. (ASK)

Students use computer software to construct personalized fractal art. (Contains 7 figures and 1 table.)

In a future that is likely to be increasingly dominated by new technology, it is important to consider what mathematics is and how it might be taught. This article discusses these and related issues in the context of both universities and schools.

We describe two classes of sequences that give rise to accessible problems for undergraduate research. These problems may be understood with virtually no prerequisites and are well suited for computer-aided investigation. The first sequence is a variation of one introduced by Stephen Wolfram in connection with his study of cellular automata. The…

To help mathematics educators realise the power of computer-based applications and modelling, this paper deals with four questions: (a) What implications does technology have for the range of applications and modelling problems that can be introduced? (b) In what cases does technology facilitate the learning of applications and modelling? (c) When…

Given a conic section, the locus of a moving point in the plane of the conic section such that the two tangent lines drawn to the conic section from the moving point are all mutually perpendicular is a curve. In the case of an ellipse and hyperbola this curve is a circle referred to as the director circle. In the case of the parabola this curve…

This note discusses the boundary in the frequency--amplitude plane for boundedness of solutions to the forced spring Duffing type equation. For fixed initial conditions and fixed parameter [epsilon] results are reported of a systematic numerical investigation on the global stability of solutions to the initial value problem as the parameters F and…

Beyond Crossroads states that mathematics faculty should (a) select technology that is accessible to students enrolled in their distance learning mathematics course, (b) advise students on the expectations of their distance learning mathematics course and orient them to the distance learning environment of their course, (c) provide students with…

The purpose of this study was to investigate the critical attributes of mathematical software designed for children between the ages of four and seven. This study sought to offer guidelines that will assist software designers in the design of developmentally appropriate educational software. In addition, teachers and parents may benefit from this…

This article discusses the importance of private interactions, in which a student works alone with learning materials, and public interactions, in which a group of students engage in discourse around learning materials. While traditional technology requires that designers choose one type of interaction over another, the authors show how handheld…

Using a case study research strategy of data collection, the empirical component of the study presented in this paper is aimed at exploring the interplay between content knowledge and pedagogy when information and communication technologies (ICT) are used by a number of secondary school mathematics teachers. An orienting framework advanced as a…

Science and mathematics educators are expected to use existing educational technologies effectively and to keep informed about emerging technologies that might become important educational tools in the not-so-distant future. This monograph offers some help in that regard by highlighting a number of existing and emerging educational technologies.…

This is the final report of a year-long research project on the implementation of a guided inquiry approach using the Geometric Supposer, a microcomputer software series, to teach high school geometry in three Boston area suburbs during the 1985-1986 school year. The project assessed student learning and examined the many and varied issues…
