| Task-based language teaching approach, combining the advantages of both traditional and modern language teaching theories, allows students to learn and use the language by a series of interactive tasks, emphasizing on communicative activities which made the aims of study as a guide under the real situation. Students can learn, analyze, understand and use language by self-directed learning. During the learning process, the emphases are on the understanding of the meaning rather than the learning style. Learning from "doing-it" is the key to learn language. The interactive learning styles will be promoted, i.e. learning from experiencing, practicing, participating, communicating and co-operating. Students can learn language by using language, finding and solving problem, understanding language, hence sensing and experiencing the success of learning at the finishing of a task. The current research is aimed at improving students' oral communication skills by using task-based teaching approach based on the cognition theory, socio-cultural theory to stimulate students' motivation for learning and promote students' self-direction, and to develop and improve creative thought and inventive consciousness of students. The current research is also attempting to explore principles of task-based teaching and its experimental research in oral English teaching in senior high school and try to find a new way in English teaching. |
