This report describes an experimental intensive core French program for grades 5 and 6 at Churchill Alternative School in Ottawa (Canada). The aim was to improve the oral French skills of core French students by providing a period of intensive exposure to French and by increasing the total number of hours in French during one program year from 120 to 450. Unlike French immersion, this "bain linguistique" provides a one-time, intensive dose of French with the more limited objective of building oral fluency and preparing students to benefit more from subsequent core French instruction. Participating students were 21 ten- and eleven-year-old students, who received instruction in French during half of the school day (French language arts, physical education, art) and regular instruction in English during the remainder of the day (English language arts, mathematics, science, social sciences). The report summarizes the program's outcomes in student gains in French listening and speaking proficiency and changes in their attitudes toward French study and use. Supporting program materials are appended. (MSE)
