The wide range of languages and purposes now served by immersion
worldwide is illustrated by case studies of thirteen programs.
Immersion, a relatively new approach to bilingual education, originated
in Canada. It uses the target language as a medium of instruction in
order to achieve "additive bilingualism" -- a high level of second
language proficiency. The wide range of languages and purposes now
served by immersion worldwide is illustrated by case studies of thirteen
programs presented and discussed in this paperback edition. The
introductory chapter defines immersion education theory and practice and
shows how this approach differs from other forms of bilingual education.
