This project focuses on the construction and use of a student-made elementary algebra tutorial World Wide Web page at the University of Memphis (Tennessee), how this helps students further explore the topics studied in elementary algebra, and how students can publish their work on the class Web page for use by other students. Practical,…

This paper introduces a teaching unit on using spiral symmetry in a geometry course for secondary education majors. The TI-92 graphing calculator is used to exploit the exponential function to analyze the geometric topic of similarity and to study the derivative of spirals. The paper provides some procedures and programs to generate spirals using…

This book seeks to develop, enhance, and expand students' understanding of mathematics by using technology. Topics covered include the advantages of spreadsheets along with the opportunity to explore the 'what if?' type of questions encountered in the problem-solving process, enhancing the user's insight into the development and use of algorithms,…

This constructivist teaching experiment investigated the role of whole-number knowledge in fraction learning. Two nine-year-old students worked for one year with a computer program (Copycat) and demonstrated that the development of whole-number knowledge and rational-number knowledge is interdependent. Contains 59 references. (KMC)

Describes a research study that determined that calculus educators are slow to use technologies in instruction because they perceive a lack of clarity regarding the use of technology, technology is rapidly changing, and using technology requires too much time and effort. (DDR)

Discusses representations in the context of solving a system of linear equations. Views representations (concrete, tables, graphs, algebraic, matrices) from perspectives of understanding, technology, generalization, exact versus approximate solution, and learning style. (KHR)

Presents an activity that capitalizes on the particular advantages of physical and computer pattern blocks. (KHR)

Describes a prime-number unit that targets middle school students learning about patterns, formulas, and large numbers while participating in a search for the largest prime number. (YDS)

Presents findings from observations of two classrooms in which teachers used an interactive whiteboard and projector. Provides ways of using the interactive whiteboard in classroom activities. (KHR)

Explores the relative strengths and weaknesses of the spreadsheet approach versus specialized mathematical programming software for solving a particular logic puzzle. (KHR)

Explores ways to help children make connections between whole-number multiplication and their notion of a fraction. Illustrates an approach to constructing fraction concepts that builds on children's whole-number knowledge using specially designed computer tools. (KHR)

Explores useful ways of teaching the volume of pyramids using cubic blocks and spreadsheets. Presents a lesson plan with teaching suggestions. (KHR)

Presents exploration activities and problems related to the concept of linear function which can be performed using Parallel Axes Representation. (PR)

Shows how to model Newton's method for approximating roots on a spreadsheet. (MKR)

Discusses the impact of computer algebra systems and evolving educational technologies on the mathematics curriculum, including fundamental assumptions, understandings that are needed, overarching priorities (acquiring and using knowledge), impact on students and parameters of instruction, and impact on faculty.
