The purpose of this study is to understand how an interdisciplinary arts/language project contributed to the linguistic and cultural development of grade 8 students from 6 different classes, in a New Brunswick francophone school. More specifically, the study concentrates on the effects of pedagogical interventions used by teachers of French, Music and Visual Arts. An arts/language project was developed in which students, depending on their choice of Music or Visual Arts classes, were given the opportunity to attain the objectives and reach the learning outcomes of their French and Music, or French and Visual Arts courses, simultaneously, while concentrating on musicians and artists from their own community. The qualitative analysis of data resulting from interviews, questionnaire and observations indicates that the arts/language project contributed to the linguistic and cultural development of the students, and that certain conditions need to be addressed in order to assure a successful interdisciplinary experience.
