IMPROVING SCHOOLING FOR LANGUAGE-MINORITY CHILDREN
This book provides a research agenda edited by Diane August and Kenji Hakuta, to improve schooling for language minority children.  Almost 30 years after congressional passage of the Bilingual Education Act as Title VII of the Hawkins-Stafford Elementary and Secondary Education Act, we are now in a position to take stock of what we know and to consider ways of improving our knowledge building in this area. This task is of critical importance given the demographics of the school-age population.
