II. Literature Review

2.1The Current Research of Interactive Teaching Approach at Home

   Interactive teaching as a teaching method, it is widely circulated during the twentieth century 30 years in western countries. The formula has not been widely adopted, in the twentieth century80 years in China. With the developing of the times, more and more scholars began to realize the importance of interactive teaching to the students, so they begin to accept the new idea and apply it to the teaching, to cultivate the students’ ability of interaction. Interaction theory includes the definitions of interaction. The hypothesis is discussed, which acts as the theoretical foundation for the empirical study.

   Interactive teaching is a kind of dialogue between teachers and students. The interactive teaching method breaks the old, traditional and single teaching mode, allowing students study autonomously. Liu guoqiang(2000) thinks that interaction essentially influences language teaching or acquisition. Interaction, with other speakers of the target language, always happens in the process of second language acquisition. Classroom interaction is to ensure that students have the opportunity to participate in the exchange of information. In order to make the teachers and students to be able to communicate harmoniously and happily. Wu Kangning(1997) has done important research to the interaction, which takes place in classroom teaching from the viewpoint of sociology. This step is a learner asking question and the speaker explanation, to make the listener clear. Concurrently, the interactive teaching approach causes the learners to certify the target language. Students can improve the language proficiency by listening or speaking. The output of other students like pair work and group work also have the equal effect. Interactive teaching is a dynamic teaching process, teaching and learning are unified to adjust the relationship between teachers and students. Some researches about foreign language interaction gradually appear in the 1980s. Many points of these researches are quotes or translates according to the foreign literature. They give students more opportunities to practice listening and speaking and create a relaxing environment for students. It aims to motivate and encourage them to speak in the target language. Therefore, some researchers argue that the classroom should be interactive in English teaching, which can develop students' communicative competence (Li Xiuying&Wang Yijing, 2000). With the improvement of our educational level. English classroom interaction attracts corresponding attention. Some researchers and teachers take some effective ways to improve students' speaking skills.

   One of the most important features of our language is that we communicate with each other. Therefor, it is considered the most important skill for learners. The interactive teaching approach can provide learners a opportunity to practice with their teacher and classmates or even with the native speakers. The beneficiaries of the interactive teaching are not only teachers but students are the ultimate beneficiaries of this teaching model. Interactive teaching approach provides the opportunities of language output for students. Interaction becomes better important than before at the information age. Some researchers put forward some effective activities in classroom interaction. One of them is interaction in the game, which is considered as one of the most effective activities in foreign language teaching and learning. Li Liuying and Wang Yijing (2000) discuss the concept as theoretical foundation of interaction. A teacher needs to keep a watchful eye on students' emotional states and create an interactive classroom atmosphere, when there is an appreciation for students' uniqueness in the class. The real interaction is strengthened. (Guo Zhengfeng, 2002).
