A synthesis of two evaluation studies is presented. The first study describes an early immersion school-based program in the province of British Columbia conducted on a longitudinal basis from kindergarten to grade 7, and sponsored by parents to extend their children's school-based bilingual experience. The longitudinal study of the early immersion program examined the effects of the program on children's performance in English language arts and mathematics, French language skills, and attitudes toward French language and culture. Comparisons were made with students in the regular English program and with those in other types of French second language programs. The second study involves a bilingual exchange program for grade 7 early immersion students which had two aspects: a cultural-lecture component on various aspects of French-Canadian culture given during the year, and a 2-week visit to the province of Quebec during which the early immersion students studied with French speaking students and their families. The evaluation study was designed to investigate the effects of each component of the exchange program on students' knowledge of and their attitudes toward various aspects of French language and culture.
