Presents ways to improve the accuracy of approximations of logarithms in a college-algebra course. (Author/ASK)

Discusses the issue of proof in school geometry and views dynamic software as an excellent tool for exploration in geometry classes, mathematical practice, and for helping students see that a theorem is true. Argues that justification without proof would be untrue to the theory and practice of mathematics. Contains 32 references. (ASK)

Indicates the importance of teaching discrete mathematics. Describes how the use of technology can enhance the teaching and learning of discrete mathematics. Explorations using Excel, Derive, and the TI-92 proved how preservice and inservice teachers experienced a new dimension in problem solving and discovery. (ASK)

Presents an activity in which students use computer-based spreadsheets to find out how much grain should be added to a chess board when a grain of rice is put on the first square, the amount is doubled for the next square, and the chess board is covered. (ASK)

Adopts several strategies for successful teaching and learning of linear algebra, which consist of a set of computer projects allowing students to explore new concepts, make conjectures, apply theorems, and work on applied projects of their choice. The resulting improvement in student learning has been remarkable. (Contains 12 references.)…

Begins with some context setting on new views of statistics and statistical education reflected in the introduction of exploratory data analysis (EDA) into the statistics curriculum. Introduces a detailed example of an EDA learning activity in the middle school that makes use of the power of the spreadsheet to mediate students' construction of…

Describes the Math Emporium at Virginia Tech, a technology-assisted learning community serving more than 7,000 students each semester; it offers a variety of mathematics teaching and learning situations, including totally online learning, tutorials, tutors, lectures on CD-ROM, group meetings, live lectures, and testing. Also describes the redesign…

Shares experiences with using "The Wall", a number patterns spreadsheet idea developed by Dave Shiers, with children in a middle school. (ASK)

Provides an overview of a Vygotskian perspective for learning from hypermedia. Utilizes a Microsoft Dinosaurs teaching-learning episode to pose questions concerning the use of hypermedia for learning of mathematics and science. (Author/MKR)

Attempts to lay the groundwork for a study of curves produced as loci using dynamic geometry. Provides some sketches of ways Cabri may be used to enhance the teaching of geometry with particular reference to synthetic plane Euclidean geometry, locus, and the conics. (Contains 26 references.) (ASK)

Discusses two knowledge domains, 'use technology' and 'teach with technology effectively' in supporting teachers' professional growth. Presents reflections from a project in which middle school teachers use computer software to improve their mathematics teaching and learning. (Contains 13 references.) (Author/ASK)

Uses the zooming technology of graphing calculators and certain graphing software to help middle school students extend their understanding of slope to curved graphs. (ASK)

Outlines the approach of a study that aimed to observe young children as they constructed meanings for randomness in computer-based setting. Provides a snapshot of two children working with the tools made available in that setting. Uses this picture to begin the formulation of a theoretical framework for the construction of meaning in one…

Visual logic puzzles provide a fertile environment for teaching multiple topics in discrete mathematics. Many puzzles can be solved by the repeated application of a small, finite set of strategies. Explicitly reasoning from a strategy to a new puzzle state illustrates theorems, proofs, and logic principles. These provide valuable, concrete…

In this paper, we present an interactive teaching approach to introduce the concept of optimal design of experiments to students. Our approach is based on the use of spreadsheets. One advantage of this approach is that no complex mathematical theory is needed nor that any design construction algorithm has to be discussed at the introductory stage.…
