OUR EXPERIENCE IN ADDRESSING AMERICAN audiences about Canadian French immersion programs has led us to approach our topic with considerable caution. To a large extent this has been because some American policy-makers and educators (e.g., Baker and de Kanter) attempted to equate Canadian French immersion programs for English-speaking Canadian children with English immersion programs for minority language children in the United States. From the point of view of the creation of a bilingual citizenry, such comparisons are inappropriate indeed (see, for example, Cohen & Swain; Swain: 2 1). That is to say that while a likely outcome of immersing a majority language child in a minority language in school is a bilingual individual, a likely outcome of immersing a minority language child in a majority language in school is a unilingual individual. However, from the point of view of second language teaching and learning, there is much to learn from the research involving Canadian immersion programs. We direct our attention in this paper to aspects of the teaching and learning process. Specifically, we intend to make two points that are strongly supported by the research from Canadian immersion programs. First, older learners may not only exhibit as much success in learning certain aspects of a second language as younger learners, but they can also accomplish this learning in a shorter period of time than can younger learners. This point, we feel, is particularly pertinent to those concerned with adult second language learners. Second, in this era of “communicative language teaching,” it is faulty to assume that one
