We give an example of a student project that experimentally explores a topic in random graph theory. We use the "Combinatorica" package in "Mathematica" to estimate the minimum number of edges needed in a random graph to have a 50 percent chance that the graph is connected. We provide the "Mathematica" code and compare it to the known theoretical…

Discusses the relative ease of obtaining library management statistics when using machine readable records and powerful software tools such as the Statistical Analysis System package. The development of such a management information system for the Cataloging in Publication division of the Library of Congress is described. (Seven notes with…

A programing approach is described, using numerical methods to draw implicit functions, without solving the relationships explicitly. Several examples are discussed, with programs and printouts included. (MNS)

Summarizes the issues covered in the 1988 literature on nonbook processing. The areas discussed include cataloging of computer files, music and sound recordings, film and video, graphic materials and three dimensional objects, cartographic materials, and preservation of nonbook materials. A bibliography of 80 sources is provided. (CLB)

Describes the use of the computer software "Graphs and Tracks" a tool for interactive computer instruction, in teaching one-dimensional kinematics concepts and connecting these concepts to their graphical representations. Provides ordering information. (JRH)

Describes one teacher's effort to change the classroom environment in order to create student-directed exploratory learning. Presents a lesson in which students use the computer program Lesson Graph to study the effects of coefficients on linear equations. (ASK)

Offers information on a project to improve students' understanding of derivatives. Students use the software package "Cactusplot" which allows them to calculate the slope at various points, and "Graphical Analysis III" software to graph the data and modify the graphs if necessary. (ASK)

This paper discusses experience with alternative assessment strategies for an introductory course in dynamical systems, where the use of computer algebra and calculus is fully integrated into the learning process, so that the standard written examination would not be appropriate. Instead, students' competence was assessed by grading three large…

In this article, the author shows some simple examples of ways in which "Autograph" can enhance learning in the KS3 curriculum. He began using version 2 with A-level students to help them visualise concepts in pure mathematics. He has "Autograph" projected to the front board to keep learners focused on mathematical activity…

Programs (using Logo) developed by children to produce multiples, the Fibonacci series, and square numbers are presented, with graphical representations of functions introduced. Another investigation involves drawing a circle using turtle graphics. (MNS)

Computer algebra systems (such as MACSYMA and muMath) can carry out many of the operations of calculus, linear algebra, and differential equations. Use of them with sketching graphs of rational functions and with other topics is discussed. (MNS)

Describes how a software package that includes a spreadsheet, a relation grapher, and a dynamic geometry can contribute to teacher training through an exploratory problem-solving course. Discusses the ways in which technology-rich environments enhance and extend traditional topics. Contains 17 references. (DDR)

Activities for enhancing students' understanding and interpreting of graphical information is provided. Four worksheets and answers are given. (YP)

Discusses a student project visualizing the surface of a function using computer graphics. Describes topics to complete the project, function and its domain, scaling, coordinate axes, projection of the surface, sketching the graph, plotting, changing the viewpoint, and rotating the axes. Provides a BASIC program using the rotation of the axes and…

Discusses the important role of graphs in conveying scientific information and the use of computer software in amplifying the value of graphs as tools for scientific investigation. Topics discussed include: skills required for analyzing and interpreting graphs, software design, and teaching and learning strategies. (JRH)
