Because of the overemphasize on L2 function and the neglect of linguistic forms, EFL learners speak neither accurately nor fluently, together with the inauthentic communicative activities and anxiety cause learners task avoidance behaviour.

As the synchronous computer-mediated communication has a great resemblance with real interaction, it also has the unique featu

22、r One Introduction1.1 A general description of the study The communicative approach aims at improving learners communicative competence shifted the emphasis in FL teaching from a focus on linguistic form to activities which involve effective communication from the1970s. In the late 1980s, the abilit

23、y to communicate seemed to have replaced grammatical accuracy as the measure of successful modern language learning even if grammatical errors occurred. However, the 1990s have seen the shortcomings of communicative approach being increasingly pointed out: engaging meaning and enabling communication

24、 might de-emphasize language grammar and form. Many EFL learners speak less accurately. In the post-communicative climate, theres an urgency: balancing form and function in FL teaching. EFL teachers now urgently need a solution to solve the inefficiency of CLT and to increase authentic exposure and

25、use of the target knowledge both inside and outside of the classroom. To foster communicative competence and achieve real L2 communication, ELT activities should realize the roles of output (triggering function, hypothesis testing, metalinguistic function, etc); the roles of interaction (meaning neg

26、otiation, feedback, modified interaction, clarification, noticing, scaffolding, zone of proximal development) and the roles of affective factors (motivation, attitude, anxiety) in SLA; follow the notions of the Output Hypothesis from a psycholinguistic perspective as a basis for depicting L2 product

27、ion process and for proposing mechanisms that influence L2 acquisition according to: Levelts model of language production together with de Bots adapted model, Andersons declarative knowledge to procedure knowledge as well as Mclaughlins controlled to automatic processing model.Due to the development

28、 of computer technology, the Internet in particular has become a new medium of communication that is shaping both the processes and the products of communication. While much second language teaching and learning has benefited from the employment of multimedia, its application is still relatively new

29、 to the teaching and learning of EFL in China. There still exists an empirical gap between the theories of CALL and its application in the area of ELT. The study was undertaken in experiment to find out if SCMC can facilitate secondary school EFL learners communicative competence by developing the s

30、ame cognitive mechanisms underlying spontaneous conversational speech. The research questions to be addressed in the study are the following: 1. What are the effects of SCMC on learners affection towards English learning?2. Whats the effect of SCMC on facilitating learners oral proficiency?3. Whats

31、the effect of SCMC on enhancing learners communicative competence?1.1.1 Thesis statementThe purpose of the paper is to prove and explore synchronous computer-mediated communication has an effect on increasing secondary school EFL learners exposure and use of the target language with native speakers

32、in a more authentic, motivated, convenient, economic and less anxious environment as well as facilitating and developing their communicative competence based on Levelt et als process and mechanism of L2 production model, the theories of output hypothesis, interactionism and affective factors. 1.1.2

33、Limitation of the studySince the use of synchronous CMC in the EFL classroom is still a young enterprise and so far the full integration of the Internet into foreign language teaching has not yet been achieved even in advanced countries. Studies conducted so far are often small-scale, sometimes some

34、what biased. Many claims have not or only partly been backed up by hard evidence, and its hard for the writer who is restricted with time and capacity to find enough references and to make a thorough, extensive and comprehensive research into the field. In addition, it is very early in experimentall

35、y examining communication competence as a result of synchronous CMC, these findings need to be replicated with different populations and different instructional treatments.1.1.3 Means of obtaining dataData mainly come from Chinese and English Publications obtained from Shenyang Normal Universitys li

36、brary and Internet resources.1.1.4 Data presentation and analysis techniquesIt is a quantitative & qualitative study. It is presented and analyzed by tables & graphs coupled with a verbal account.1.2 Need for the studyThe study is to find the theoretical basis for applying SCMC into EFL teaching; to

37、 provide a practical solution to the problem of EFL learners lack of chances for English output and the ineffectiveness in communicative class, thus it realizes the ultimate goal of English teaching.The objectives of the paper are:A) to present the inefficiency of the communicative language teaching

38、. B) to find theoretical basis for applying synchronous computer-mediatedcommunication into EFL teaching.C) to increase EFL learners exposure and use of the target language in a more authentic, motivated, convenient, economic and less anxious environment.D) to enhance learners communicative competen

39、ces via SCMC thus to solve theproblem of Chinese EFL learners low capability of communication.E) to provide a new access to assist and realize the ultimate goal of English Teaching.F) to guide the students to use the computer as a tool for language learning.1.3 The overall structure of the thesisThi

40、s thesis consists of five chapters:Chapter One is the introduction of the thesis with a general description of the study, need for the study and the overall structure of the thesis.Chapter Two is the part of literature review. First it reviews the coming of communicative approach, the notion of comm

41、unicative competence and points out the problems in the CLT classroom. Then it introduces the theories of SLA: the roles of output, interaction and affective factors to L2 acquisition. The core of the theories is Levelts process and mechanism of L1 language production, de Bots adapted model, Anderso

42、ns declarativeprocedural knowledge model and Mclaughlins information processing model. What follows that is the introduction of synchronous computer-mediated communication, including: CALL development, interpretation and features of SCMC and studies of SCMC and language learning.Chapter Three is the

43、 section of methodology. It supplies research questions, design of the research experiment, briefly includes the subject and settings of the research; treatment and procedures of the experiment; the instruments of the research are mainly questionnaire and pre-test/post-test comparison of the experim

44、ent; then it illustrates how the data is collected and analyzed to prove the reliability and validity of the statistics.Chapter Four is the results and discussion of the experiment. It consists of the analysis of the questionnaires comparisons and the analysis of the pretest and posttest comparisons, the major findings of the research questions after the experiment, limitations of the present study and the suggestions for further study.Chap
