In recent years geometry seems to have lost large parts of its former
central position in mathematics teaching in most countries. However, new
trends have begun to counteract this tendency. There is an increasing
awareness that geometry plays a key role in mathematics and learning
mathematics. Although geometry has been eclipsed in the mathematics
curriculum, research in geometry has blossomed as new ideas have arisen
from inside mathematics and other disciplines, including computer
science.
Due to reassessment of the role of geometry, mathematics educators and
mathematicians face new challenges. In the present ICMI study, the whole
spectrum of teaching and learning of geometry is analysed. Experts from
all over the world took part in this study, which was conducted on the
basis of recent international research, case studies, and reports on
actual school practice.
This book will be of particular interest to mathematics educators and
mathematicians who are involved in the teaching of geometry at all
educational levels, as well as to researchers in mathematics education.
