As reform in all sectors of education continues, it is becoming increasingly important that we develop a rich understanding of what "intelligence" is, and how it can be improved. Reflecting current views on the manifestation, development, and assessment of human intelligence, this volume addresses a rich diversity of theoretical, methodological, and applied issues -- a number of which have not been raised previously. The contributors to this collection -- highly regarded experts from various countries -- propose perspectives for future research, their intent being not so much to predict the future, but to help shape it.
