ExCELS is a program that supports teachers interested in the use of computer interfacing at the secondary school level. This paper describes an ExCEL-based course developed for science education majors, presents an overview of interface apparatus and how it is used in schools, and gives examples of experiments performed. (LZ)

Describes a simulation-oriented computer microworld named CHANCE used to overcome the limitations of physical materials for experiments in teaching and learning introductory probability. Results of a teaching experiment conducted with four middle school and high school students are discussed. (15 references) (LZ)

This article describes the functionality and use of a computer-based tool, called MultiMap, for investigating the properties of mappings of the plane onto itself. Examples are given of activities appropriate for mathematics students from middle school to college. (LZ)

This report describes an integrated life science/physical science HyperCard library used to enhance active learning and interdisciplinary classroom strategies. The rationale for the design of multitier problem sets as part of the library is discussed and examples of multitier question groups are given. (33 references) (LZ)

This review examines the use of spreadsheets to introduce students to elementary concepts of mathematical dynamical systems. Key definitions from this field as well as specific assignments that were given as part of an elective mathematics course are discussed. (LZ)

This paper presents a sequence of computer-based activities aimed at achieving an intuitive understanding of the ideas and concepts underlying the Fundamental Theorem of Algebra. Deductive proofs to support students' empirical investigations are also discussed. (LZ)

This paper advocates the use of symbolic computation packages as another aid in teaching geometry. The need for such packages and their use in computerized proofs are demonstrated by a problem in high school planar geometry. (LZ)

In this paper, experiments with equal-length and different-length coupled pendulums were carried out measuring the frequency of energy exchange between them using microcomputer-based technology. The experiment described in this paper would be most appropriate for an introductory mechanics laboratory course. (15 references) (LZ)

Presents the need for the integration of telecommunications into mathematics and science instruction, provides an overview of telecommunications, shares examples of the use of telecommunications, and closes with a cautionary note on how telecommunication is integrated into mathematics and science instruction. (Author/MKR)

Presents Internet connections appropriate for mathematics education; provides descriptions of ways that mathematics educators can access electronic resources such as e-mail, discussion groups, gopher servers, and transfer of files; and provides hints and examples from classroom connections and professional applications. (18 references) (Author/MKR)

Describes the use of telecommunications in a secondary science education program that has students use the Internet by way of e-mail, teleneting, gophering, and file transfers to find information. (22 references) (Author/MKR)

A preservice teacher education course involving the applications for a computer within the mathematics classroom is described in terms of its evolution from a workshop to a regular curricular offering. Included are samples of computer experiments which suggest computer teaching activities for the prospective teacher lacking in field experience.…

This article provides pedagogical techniques that require active student participation in the use of computer spreadsheets while determining recursive numerical solutions to equations. Included are several computer screen displays which illustrate the various advantages in using spreadsheets specific to synthetic division, the bisection method,…

Discusses the use of computer visualization to motivate and support mathematical dialogues. Describes the "Scientific Visualization Software Suite," a set of public domain visualization tools from the National Center for Supercomputing Applications. (Author/MDH)

Describes a unit for teaching exponential change in a noncalculus physics course by having students write recursive procedures in LOGO to graphically represent linear and exponential change. Summarizes the experience of implementing the unit in a segment on radioactive decay. Modifications to the unit are suggested for teaching exponential change…
