Therefore, which teaching method fits CAI most becomes a new task challenging English teachers. And, how to use CAI as an assistant in reading teaching is the main task to English teachers. Many teachers can’t have a good understanding of the reason of using computer assisted language learning. They doubt whether it is useful or effective by using computer which takes several more hours in preparing for each lesson. However, instead of wasting time, the use of CAI will not only captivate the teaching community, but also increase the productivity in teaching process with the help of TBLT. TBLT is quite different from the traditional teaching method such as the PPP approach which includes presentation, practice and production. It is defined as: an analytic approach to syllabus design and methodology in which chains of information-gathering, problem-solving and evaluative tasks are used to organize language teaching and learning; these interdependent pedagogical tasks, which combing insights from sociolinguistic and psycholinguistic research, are designed to methodologically simulate the communicative events which learners encounter in specific second language-using environment. (Markee 1997: 47) That’s to say, TBLT can help CAI play the greatest role.
The thesis first states the status-quo of reading teaching in middle school in China. Then it takes “The Story of Xi Wang”（8AU5 Oxford English）as an example to analyze the feature of CAI in reading teaching from the perspective of Task-based Teaching Approach which includes pre-task, while-task and post-task activities. In the end, in this thesis, what experiences can be drawn from the successful arrangement of reading class by using CAI is included. By concluding problems existing in the use of CAI in class teaching, we can take some measures to solve the problems and promote the development of CAI in reading teaching from the perspectives of teachers and students.
2. Literature Review
The development of CAI in teaching has been studied by many scholars both at home and abroad. Some scholars focused on the learning environment. Some scholars connected the class teaching with distance education through the use of CAI. Some scholars analyzed the important factors of CAI which made it a useful assistant. Tsai, S. W.&Pohl, N. F had ever done an experiment in their book ‘Computer Assisted Instructional Augmented with Planned Teacher/Student Contact’ which presents the situation of CAI used in class teaching and why CAI is so widely applied in English teaching(Tsai, S. W.&Pohl, N. F,1980). And J.P.Hasebrook (1995), published in Psyclit Journal Articals that“ The effective use of multimedia is influenced by many internal and external factors，like motivation, knowledge, mode and contents of media, learning strategies, features of the task, etc.” (Hasebrook 1995: 5) which discovered some problems existed of the way of how to use CAI in class that we must pay attention to. Hermann(1980) once studied 750 German adolescent learners of English. She found that those who have been studying for five years or more had a more positive attitude to the second language culture than those who were just new learners. This experiment shows the importance of motivation raised by the success they are gaining from learning. From my perspective, this thesis, based on the theory of task-based teaching approach, analyzes the use of CAI in a specific reading teaching to further comprehend the importance and function of it, and meanwhile to gain deep understanding of this medium.
