9、付行为,学生的口语交际能力即使经过几年的学习也没有得到提高。本文以认知主义理论和二语习得理论为基础，通过分析言语输出假设，交互理论和情感因素理论在二语习得中的作用，参考了levelt 和 de bot 的言语输出模式，anderson 的从陈述性知识到过程性知识的三个阶段 和 mclaughlin 的言语加工过程的理论，认为促进与实现真正的口语交际能力的教学活动必须遵循言语输出的过程与机制,在交际活动中实现言语输出,言语交互和情感因素对二语习得的作用。 随着信息技术与因特网的发展，多媒体与网络越来越多地应用于外语教学，作为电脑技术的重要部分，电脑实时同步交互为英语学习者提供了更多的，轻松方便的

10、， 经济的，不受时间地域限制的与英语本族语言者进行真实交际的机会。由于电脑实时同步交互兼具文本交互与语音交互的特点，它符合言语输出的过程和机制，类似于真实交际，但它降低了交际过程的速度，使交际者有时间考虑言语的内容与形式，因而电脑实时同步交互有可能弥补课堂交际的不足。本文通过实验，用问卷调查和口语测试的方法比较实验组（利用电脑实时同步交互）和控制组（在传统课堂交际环境下），通过数据的分析，推断出电脑实时同步交互在情感方面对英语学习者具有降低焦虑感，提高学习兴趣与动机，形成正确的学习态度的作用，对学习者的口语能力水平具有提高的作用，对学习者的交际能力具有促进的作用。关键词: 交际能力，电脑实时交

22、apter 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 ab

23、ility 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 communica

24、tion 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

25、and 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

26、 negotiation, 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 pro

28、ment 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

29、 new 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 t

33、1.2 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

34、somewhat 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 experimen

35、tally 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 university

46、guage teachingcommunicative language teaching began in britain in the 1960s as a replacement to the earlier structural method, called situational language teaching. this was partly in response to chomskys criticisms of structural theories of language and partly based on the theories of british funct

47、ional linguistis, such as firth and halliday, as well as american sociolinguists, such as hymes, gumperz and labov and the writings of austin and searle on speech acts. communicative approach in language teaching starts from the notion of “competence” which was first put forward by chomsky(1965), an

48、d then was constantly extended by many other linguists such as hymes(1972), canale and swain(1980,1983).communicative competence and communicative approachit was chomsky who first differentiated the two notions of linguistic competence and performance. competence refers to the internalized knowledge

49、 of the structures, rules and systems of a particular language while performance refers to the actual manipulation and application of the underlying knowledge. chomskys notion of competence and performance is of great significance. yet, his competence only discusses linguistic knowledge, its scope b

50、eing too narrow. hymes extended the scope of chomskys linguistic competence into four aspects and proposed the notion of communicative competence. he maintains that a person who acquires communicative competence acquires both knowledge and ability for language use with respect to:(1) whether (and to

51、 what degree) something is formally possible ( the correctness ofa certain language form);(2) whether (and to what degree) something is appropriate in relation to its context in which it is used and evaluated (the appropriateness of a language form in a specific context);(3) whether (and to what deg

52、ree) something is feasible in virtue of the means of implementation available (the practicality of a language form);(4) whether (and to what degree) something is in fact done, actually performed, (theactual performance of a language form in reality) (hymes,1972:281)hymes proposal of the notion of co

53、mmunicative competence is further clarified by canale and swain. according to canale and swain, four dimensions of communicative competence are identified: grammatical competence, sociolinguistic competence, discourse competence and strategic competence.grammatical competence refers to what chomsky

54、calls linguistic competence and what hymes intends by what is “formally possible”. it is the domain of grammatical and lexical capacity.sociolinguistic competence refers to an understanding of the social context in which communication takes place, including role relationships, the shared information of the participants, and the communicative purpose for their interaction. to put it more specifically, it is the ability to use language appropriately in various social contexts.discourse competence refers to the
