9 ' ( ' ( Au cours de mon expérience, longue d une vingtaine d années, d enseignement du FLE à l Université en Chine, j ai assisté à une période d évolution méthodologique de cet enseignement. L objectif de cette évolution est de satisfaire le besoin de communication en langue étrangère dans le cadre de la politique d ouverture de la Chine mise en œuvre à partir de En ce qui concerne l enseignement de la langue étrangère dans l enseignement supérieur, la transition entre enseignement traditionnel et enseignement communicatif est devenue le problème le plus souvent posé. Fondé sur une relation pédagogique forte dans laquelle l enseignant joue le rôle central, l enseignement dit traditionnel existe depuis longtemps et met l accent sur la connaissance de la langue tout en considérant que le savoir métalinguistique constitue une partie de la discipline universitaire : «savoir une langue, c est plus ou moins connaître le système à l égal du maître c est le vocabulaire et la grammaire qui représentent les objectifs immédiats» (P.Martinez, 2002 :49). L approche est très analytique et les outils privilégiés sont le manuel ou bien un autre support linguistique avec des explications en langue maternelle. Dans le même temps, l approche directe, l approche audiovisuelle, l approche communicative essaient de mettre les apprenants au centre des activités en classe, en considérant que «le langage est désormais perçu d abord comme un moyen d agir sur le réel, et les formes linguistiques ne prennent leur sens que dans des normes partagées, savoir une langue, c est savoir communiquer en connaissant la règle du jeu» (P.Martinez, 2002 :72). Face à ces deux grands courants méthodologiques, à mon poste de travail, ma première préoccupation est d essayer d élever la compétence linguistique et la compétence communicative des apprenants de FLE. L évolution méthodologique de l enseignement des langues étrangères en Chine nous conduit ces dix dernières années à réfléchir sur la relation existant entre ces deux courants. Nous trouvons qu ils sont complémentaires au niveau des activités didactiques comme les deux «courants» du Rhône et de la Saône à Lyon se dirigeant vers le même «objectif» : ce qui compte, c est de faire des progrès en langue d une part, et de savoir se servir de la langue d autre part, surtout pour les apprenants débutants en milieu universitaire. Comme l enseignement traditionnel qui prenait le lexique et la grammaire comme buts de la connaissance universitaire est loin d envisager la langue comme un instrument communicatif, on cherche une nouvelle approche plus dynamique, plus interactionnelle pour la classe de langue étrangère. L enseignant, objet central de notre recherche, joue un rôle déterminant dans tout le processus d enseignement pour favoriser l acquisition de la connaissance linguistique et gérer l interaction didactique. Dans l enseignement / apprentissage de la langue française en milieu universitaire, les apprenants et les enseignants sont confrontés à plusieurs problèmes, sur lesquels des linguistes et des sociolinguistes ont beaucoup travaillé. Pour étudier l enseignement / apprentissage de la langue étrangère, l analyse de l interaction didactique entre les apprenants et l enseignant en classe de FLE est nécessaire. Cette analyse nous permet d aborder des problémes tels que l efficacité des activités didactiques en classe, les fonctions de l enseignant dans ces activités, les comportements langagiers des apprenants et de l enseignant en classe, la nature du contrat de communication et du contrat didactique qui les lient etc. Etant donné que l interaction didactique entre l enseignant et son groupe d apprenants dans le cadre d un enseignement / apprentissage du FLE constitue l objet de notre recherche, nous 3 I ;

10 1 % $, - * % ' " nous intéressons aux trois grands rôles simultanés que joue tout enseignant en classe de langue : fournisseur de savoir, meneur d activités, évaluateur (cf. Dabène, 1988). Nous espérons que notre étude de ces questions donnera à nos collègues chinois ou français un nouvel éclairage sur un domaine didactique en pleine évolution mais aussi en pleine progression, celui de l enseignement du français en Chine. 3 I ;
