An in-progress research project evaluating the first phase of two-year bilingual exchange programs is described. The exchange programs being evaluated are a summer exchange between groups of school children from schools in Quebec and Ontario and a school-year exchange between groups of children from schools in the same provinces. The objectives of both exchanges are increased proficiency in the second language and improved understanding of the other cultural group. The first phase of the study is concerned with: (1) the development of appropriate procedures for evaluation, and (2) the collection of initial information on language achievement and cultural and attitudinal changes among the anglophone and francophone participants. The evaluation procedures include pencil and paper tests, a language proficiency interview, questionnaires, and general interviews. Two noteworthy findings are: (1) in spite of the short duration of the exchanges, there is noticeable improvement in language proficiency; and (2) unless prompted by a questionnaire or attitude test, students reject the conventional attitudinal stereotypes. They tended instead to report their experiences in terms of specific people, activities or events. (Author/PMJ)
