As an ideological weapon of American mainstream society

assimilation theory has long dispelled languages and cultures that are different from theirs

failing to meet the needs of Special language education of numerous minority children.In the 1960s

the rising cultural pluralism appealed that any unique language and culture should be respected and recognized

and also guarantee an equal right.Multicultural theory provides a cultural perspective to study American language policy and contributes to clarifying the effect of both ideology of mainstream society and cultural value on American language education policy

and its implicit "cultural hegemony" and trend of neglect of cultural value of minority language children

thus providing all children with an opportunity to make personal dignity respected by the society.
