Immersion programs are the fastest growing and most effective type of foreign language program currently available in U.S. schools. Most immersion students can be expected to reach higher levels of second language proficiency than students in other school-based language programs. (Met, M. (Ed.). (1998). Critical issues in early second language learning. New York: Scott Foresman—Addison Wesley). Becoming bilingual opens the door to communication with more people in more places, and many parents want to provide their children with skills to interact competently in an increasingly interdependent world community.
In addition to reaping the social and economic advantages of bilingualism, immersion learners benefit cognitively, exhibiting greater nonverbal problem-solving abilities and more flexible thinking (see reviews in Met, 1998). It has been suggested that the very processes learners need to use to make sense of the teacher’s meaning make them pay closer attention and think harder. These processes, in turn, appear to have a positive effect on cognitive development.
From the standpoint of academic achievement, over three decades of studies consistently show that immersion students achieve as well as or better than non-immersion peers on standardized measures of verbal and mathematics skills administered in English (Cloud, Genesee, & Hamayan, 2000; Genesee, 1987).
