【Abstract】 This thesis starts with a review of theories of bilingualism and bilingual education,with particular emphasis upon bilingual acquisition,cognitive,affective and academic development,bilingual education models and assessment,bilingual education and social justice.It then argues that bilingual education is a feasible transformative education practice to educate children in the twenty-first century.Controversies and debates revolving around bilingual education have to be explained in reference to the social,political,ideological,cultural,and economic factors,rather than the education itself.It is finally suggested that a main theoretical hard nut to be cracked in todays multilingual,multimodal communicative networks is to establish bilingual education models meeting the specific needs of a variety of groups,especially those from minorities and weak groups in the hope that intergroup understanding and friendship can be enhanced and social justice can be achieved.更多还原
