【摘要】 外语学习的成功与否最根本的决定因素在于对目的语词汇层面的理解与掌握，在掌握一门语言中词汇的重要性是不容置疑的。但对于中学阶段的英语学习者来说，词汇学习一直以来是个难题，已成为英语学习的最大障碍，从而导致我国中学阶段的外语整体学习效率较低。本论文针对这种现象，从多媒体及网络技术对外语学习的变革出发，探讨了多媒体及网络技术的发展对高中生词汇拓展策略的意义。作者认为，随着多媒体及网络技术等现代科技的发展，为学习外语提供了真实语言环境，外语学习的环境与条件得到了极大的改善与提高。因此，借助多媒体及网络技术从多个层面分析研究我国高中学生的英语词汇学习策略，将对提高现阶段的高中英语教学效率具有一定的积极意义，为高中生将来成功地学习和运用外语奠定良好的基础提供积极的帮助。 论文作者从认知主义及建构主义学习理论出发，回顾了目前的词汇拓展策略研究现状；分析了多媒体及网络技术对词汇拓展策略的影响；并尝试结合现代多媒体及网络技术所具备的对语言学习的优势从实践中来探讨信息时代的高中生英语词汇拓展策略。文章首先介绍了通过语义场策略中的词汇的上下义关系及习惯搭配来拓展词汇的研究并探讨了多媒体及网络技术中的搜索引擎功能和丰富的语料库资源对其的积极影响。又介绍了通过语境策略中的阅读及交际两个方面来拓展词汇的策略并分析了多媒体及网络技术条件下的超文本链接功能及虚拟真实情境对此策略的意义。 在全面论述了词汇拓展策略研究现状和多媒体及网络技术对其的影响后，作者介绍了以建构主义学习理论为基础的多媒体及网络技术辅助的教学总体构想模式，并重点介绍了其近两年来就各种教学模式下的词汇拓展策略进行的教学实验及实践。主要包括个别化学习模式下学生外语学习尤其是词汇拓展的实验、课堂及课外学生协作学习模式的实践、课堂示教及网络协同教学模式下的CAI实践等。在这些教学模式的实践中，作者以认知主义和建构主义学习理论为依据，充分利用多媒体及网络技术来设计教师的“教”及学生的“学”，八 硕士学位论文 ＼N72Ky VV11’K H 讣US提高了词汇教学的效率并促成了学生自主学习能力的发展。通过这些实验及实践取得的成果，笔者讨论了其对高中生词汇拓展的启示，并提出了在基于多媒体及网络技术拓展学生词汇量的具体实践操作过程中存在着如何对学生进行有效监控及检测，以求克服存在的弊端而达到目的效果最优化的问题。 在此基础上，作者提出了多媒体电脑及网络技术的发展使传统意义上的外语学习及其词汇发展盲了“习得”可能的观点，并结合众多语言学者的研究成果分析了这种可能对外语学习的重要意义。作者还展望了多媒体电脑及网络技术的发展在外语学习包括词汇拓展上为教师的教学及学生的自学带未的极大便利和深远影响。如果充分有效地利用其忧势来辅助外语学习，则中学阶段一门外语基本过关的理想不是没有可能实现的。最后，笔者就本研究目前存在的问题进行了分析，认为在未来教育的人脑、电脑加网络的趋势下，教师要帮助学生培养正确的网络意识，克服网络的消极影响，积极利用其优势辅助自己的学习，增长自己的见识。同时教师要改变自己传统的教学观点，要变“教”为“导”，负贡学习材料的选择、学习过程的组织与监督、学习结果的考查与分析；学生要从被动接受依赖教师的状态及思想转变为主动探索建构自己的知识体系及方法。在外语学习尤其是词汇拓展上要充分利用及挖掘多媒体电脑及网络存在的优势，作自主的外语学习者。更多还原

【Abstract】 The acquisition of vocabulary has long been felt to be a crucial factor in learning a foreign language. Vocabulary development of our high school students has long been a difficult problem in our country and this results in lower efficiency in foreign language learning at high school. This dissertation tries to discuss the use of the rapid developing multimedia and network technology in vocabulary enlargement in high school context.First the author discusses the significance of the rapid developing multimedia and network technology in relation to the vocabulary expansion of high school students from the perspective of reforming language teaching and learning under the guidance of modern educational technology; analyzes the importance to enlarge the students’ vocabulary; raises the problems existing at present in traditional language teaching and learning at high school and considers it necessary to revolutionize this situation under the development of multimedia and network.After that, the author reviews the current vocabulary acquisition research; introduces some vocabulary developing strategies such as learning vocabulary in semantic field including hyponyms and hypernyms as well as collocations and developing vocabulary from contexts in reading together with oral and written communication. The author also provides a detailed survey on the relationship between teaching and learning vocabulary with the assistance of multimedia and network technology and tries to illustrate how to make good use of multimedia and network technology so as to facilitate the vocabulary expansion of high school students in the process of teaching. The author mainly explores how to use the search engine and hypertext link in websites and make proper use of the abundant corpus and actual vivid virtual cyberworld.Based on constructivist learning theories the author introduces the foreign language teaching and learning models including individual learning, cooperativelearning, classroom learning, Internet cooperative learning as well as virtual reality learning and presents the results of her experiment and teaching practice under the guidance of these models. She made the experiment based on individual learning model and it leads to some implications on teaching and learning vocabulary at high school. The author argues that the cognitive-process in vocabulary learning to be meaningful instead of mechanical favored in traditional views and suggests that both teachers and students should modify vocabulary expanding strategies. The author also proposes task-based teaching an immersion approach in vocabulary developing through network, appropriate modification of resources in network according to the students’ level ; highlights expanding vocabulary through abundant reading.After analyzing the results of her experiment and practice, the author concludes that there’s possibility of acquisition of vocabulary (instead of learning) even in foreign language study under the condition of multimedia and network technology and suggests both teachers and students should innovate their teaching and learning strategies tapping the fast developing teaching technology and network.The author also mentioned some disadvantages of network and problems of how to diminish such negative effects in order to arose people to do further research. It is worth noting that studying through network needs careful supervision, requiring good self-control and self-organization on the part of students.更多还原
