Geometry Turned On: Dynamic Software in Learning, Teaching, and Research [Pehme köide]

Shows how to use dynamic geometry (exploratory geometry carried out with interactive computer software) in the study and teaching of geometry, for use in teacher preparation courses, courses on the use of computers in teaching, and courses that focus on the use of software in doing experimental mathematics for construction and design. Topics include the role of proof in computer-based geometry, dynamic visualization in calculus, and software such as Geometer's Sketchpad and Cabri Geometry. Some of the dynamic sketches referred to in the book are available on a Web page. Includes contacts for software vendors. No index. Annotation c. by Book News, Inc., Portland, Or.

Articles about the uses of active, exploratory geometry carried out with interactive computer software.

This volume is a collection of articles about dynamic geometry: active, exploratory geometry carried out with interactive computer software. This software has had a profound effect on classroom teaching wherever it has been introduced. Unconstrained parts of the configurations are moveable - they can literally be grabbed with a cursor (using a mouse) and be dragged or stretched - and as they move, all other objects in the configuration automatically self-adjust, preserving all dependent relationships and constraints. The software has also become an indispensable research tool for mathematicians and scientists. This book gives many examples of the ways in which it can be used, and some of the effects it can have. It raises various questions for teaching and research. Some articles address the basic question, 'What is dynamic geometry good for?' as they discuss: accuracy of construction, visualization, exploration and discovery, motivating proof, transformations, tracing loci, simulation, and creating microworlds.
