This volume reflects an appreciation of the interactive roles of subject matter, teacher, student, and technologies in designing classrooms that promote understanding of geometry and space. Although these elements of geometry education are mutually constituted, the book is organized to highlight, first, the editors' vision of a general geometry education; second, the development of student thinking in everyday and classroom contexts; and third, the role of technologies.
Rather than looking to high school geometry as the locus--and all too often, the apex--of geometric reasoning, the contributors to this volume suggest that reasoning about space can and should be successfully integrated with other forms of mathematics, starting at the elementary level and continuing through high school. Reintegrating spatial reasoning into the mathematical mainstream--indeed, placing it at the core of K-12 mathematics environments that promote learning with understanding--will mean increased attention to problems in modeling, structure, and design and reinvigoration of traditional topics such as measure, dimension, and form. Further, the editors' position is that the teaching of geometry and spatial visualization in school should not be compressed into a characterization of Greek geometry, but should include attention to contributions to the mathematics of space that developed subsequent to those of the Greeks.
This volume is essential reading for those involved in mathematics education at all levels, including university faculty, researchers, and graduate students.
"The text effectively moves the reader toward a geometry and space curriculum that may open doors for many students….The ideas in this book are of high quality, well communicated and extensively referenced. Although the book is very dense with complex ideas, the vision of teaching and learning about geometry and space and the many useful frameworks, summaries of theory, and rich examples make the text a useful resource."
"…makes interesting reading for anyone nurturing an interest in the psychology of mathematics, especially for those involved in or contemplating research in the area….Hershkowitz's praise for ths work as pace-setter for change in mathematics education seems entirely justified….for a plethora of ideas about manipulation of visuospatial mathematical learning, look no further than the present volume."

"Chazan and Lehrer have produced an important book at an opportune time. It will guide researchers and teachers in re-establishing geometry as a 'non-skippable' part of every child's mathematical education."
—Canadian Journal of Science
