Bilingual education involves the teaching of two languages for academic instruction and content. According to Andersson and Boyer (1970) in Bilingual Schooling in the United States, "Bilingual education is instruction in two languages and the use of those two languages as mediums of instruction for any part, or all, of the school curriculum."
In bilingual education, both languages are considered equally important; one is not favored over the other. Content and delivery are provided in the two languages rather than one of the languages being taught as a subject by itself. In bilingual education, none of the languages should be lost, altered or diluted.
In Canada, both French and English are official languages. The Canadian Constitution provides for the use of both languages. Although French-Canadians are making serious attempts to get to a French unilingualism, it is unthinkable to seek the homogenization of linguistically diverse groups. In addition, in current times, the acquisition of more than one language remains a plus. While French is estimated as having 110 million native speakers and 190 million second language speakers worldwide, English has become the lingua franca, the language of choice for business and computers.
