An Ontario program providing sets of problem-solving activities for native French speakers helps students in grades 7-12 enrich their language proficiency in both French and English. The guides developed as part of the program emphasize language as a tool for thought, social interaction, and artistic expression, and focus on the integration of receptive and productive skills in authentic and collaborative language-learning and language-use environments. Among the early results of the program is the finding that students and teachers are receptive to the idea that the teacher's role is to transfer responsibility for minority culture and language enrichment to the learners. The interest in problem-solving activities comes from cognitive development research, and the activities range from small-group tasks to two-week projects and drama productions taking several months. Key characteristics of the tasks include variable focus, differentiation, mutual support, generation of new activities and various types of motivation, language variety, variety of problems and the strategies they produce, and the naturalness with which language and other skill areas or cognitive systems are integrated. Language-use strategies are emphasized as important, in combination with language development and problem-solving activities, for the development of interactional and critical thinking skills. (MSE)
