On the subject of geometry, Geometry Turned On does not shy away from addressing whether the striking visuals generated by dynamic contructions might cause students to question the need for formal proof. Three articles argue convincingly that the software can, in fact, heighten students' interest in proof and help them search for supporting evidence.
Best of all, many of the sketches described in the book are available to download from the Web. With a basic familiarity with the software and the sketches in hand, you will have many hours of enjoyable learning ahead. -- The Mathematics Teacher
This fine collection of articles contains superb material for anyone thinking of using an interactive computer program. The knowledgeable contributors to this volume discuss how they have used various problems in their own research and to enhance their teaching of geometry. -- The College Mathematics Journal
This is an idea book...Teachers of geometry will find many ideas for their students in this volume. Others will find ideas relating geometry to mathematical analysis, optometry aerodynmaics, and even the history of mathematics. -- Science Books and Films
