Apart from enriching exposition of the language ability, the strategy will be in the capacity as an independent part of the language skills. And explain the relative importance of implementation factor. Theoretical Basis of the Topic Piaget39。s TheoryConstructivist learning concept proposed that knowledge is not simply to be taught by teachers, but to be learned by each student in a certain situation (social and cultural background).Students can obtain knowledge and information by making use of other people, using the necessary learning materials through interpersonal cooperation, and taking the initiative to construct meaning. Therefore, the situation, collaboration and conversation and constructing meaning are the four elements in the learning environment. American ScholarAlan Andean amp。Weir about “Role Play” “Role play” teaching model will simulate the process of contact between members of the society. Students through the way of consultation, study each kind of academic knowledge, in order that they can solve the social problem effectively in the future. Related Studies Researches AbroadThe overseas studies on outofclass activities may trace to the Plato and Rousseau time. Plato is the renowned philosopher in ancient Greece. He advocates “the child playground” educational mode. That is the prototype of extracurricular activities. By the time of French Enlightenment and Rousseau (18th century), direct experience has received wide acceptance. Rousseau stressed outside world without books, no materials other than the facts, and advocated natural mode of education. To the United States in the 19th century, the first school in the world which use activity curriculum theory as teaching guidance Dewey39。s Chicago experimental school, has founded. With 18961903 Dewey Chicago experimental courses in school activities the United States began to criticize the traditional courses. Instead of it are the outofclass educational activities. These activity courses are based on the pragmatism, lasted more than 50 years in American schools, and their affects are profound and widespread. Researches in ChinaIn our country, no matter what stage, these courses have different names, for example, outofclass activities, the second classroom, class activities, integrated social practice and so on. The process of changes is closely related to our theoretical study courses. In history, the development of activity courses is closely related the progress and reform and guiding rules of the government.3. Presentation of the English Teaching The Drawbacks of Traditional Teaching MethodsReviewing the traditional English teaching method, in the past decades we have indeed made the very big progress. But with social progress and development, its shortings are also increasingly revealed.First, because the Chinese test system is imperfect, the traditional English teaching method is just an examinationoriented education model. In this teaching, evaluation of English level is to see the scores. This causes many students to get a high score, but they can not municate with people using English. Secondly, in the traditional English teaching, teacher is the leader, takes the most important part in the classroom. The teacher stands on the platform proposing the questions, analyzing and explaining them, grasping the entire teaching process. And the student is just passive audience, understands the content passively, and records the massive notes. Such teaching method does not have interaction。 hardly train student’s municative ability and language ability. Third, in teaching, to stress the accuracy of knowledge, teachers usually use Chinese to explain. So students have very little opportunity to municate using English. Obviously, the traditional English teaching is knowledgebased. Compared with the language plastic function, it pays more attention to the form of language and the grammatical function, rather than raises the munication and utilization ability of it. Modern Interest Teaching——CLT Definition of CLTThe content of municative language teaching is mainly on the language functions. Emphasis carries on language teaching in the real scene, advocating teaching process to socialization, and cultivating the ability of application, studying for the purpose of application. While prominent municative language teaching, auxiliary by some grammar, translation, sentence and so on, is based on the goal to promote the culture language municative petence.The core of municative language teaching is to put the teaching process as a process of munication. The basic principles of teaching may be summarized:The language is the information carrier, is the tool of munications. The language teaching must realize munication through each kind of activities.Language utilization39。s smoothness is more important than accuracy. Making mistake is natural and inevitable。 we may correct them gradually in the learning process.Students should take the main part in teaching process. The teacher must stimulate the students39。 enthusiasm and initiative participation。 make students enhance munication ability in the language utilization. Communicative language teaching advocated the fully participation of the students. Teacher39。s duty is to provide and create the real human relations scene, enable students to utilize the language freely and initiatively. The Content and Substance of CLTThe purpose of the municative language teaching is to cultivate students39。 munication ability. It’s the heuristic method of teaching. Induce the students to speak English boldly. Provide as much as possible drill opportunities for
