電子詞典增強下的詞匯學習模式

內容概要

　　EFL學習者詞匯匱乏是一個亟待解決的問題。為幫助外語學習者學習詞匯，本書描述了作者博士論文的研究成果：設計一個電子詞典增強下的詞匯學習模式（EDEVOL
Model）。該詞匯學習模式旨在:（1）幫助學生學習目標詞的詞義；（2）幫助學生學習目標詞的拼寫形式。本研究表明EDEVOL
Model可以作為幫助

章節(jié)摘錄

版權頁：   插圖：   This chapter introduces the statement of the problem，the rationale，theresearch hypothesis，the purposes，the research questions，and the significance ofthis study．Definitions of main terms are given，too． 1．1 Statement of the problem Vocabulary is regarded as an essential element in language learning by bothteachers and learners．Learners’lack of sufficient vocabulary is always animportant problem calling for solutions in EFL（English as a foreign language）teaching and learning．As Nation（1990，p．2）says，“Learners feel that many oftheir difficulties in both receptive and productive language use result from aninadequate vocabulary”．If learners are shofl of words．they cannot communicateproperly with others，nor can they express ideas clearly when speaking or writing．With many unknown words，it is also difficult for learners to make out what theyare told or what they are reading．How to help students learn vocabulary is aquestion language teachers have to consider．Vocabulary enlargement is the keyfor solving this problem． 1．2 Rationale of the study With the advent of computers and the Internet，a new possibility to enhancevocabulary learning is brought into the filed of EFL language learning．Becauseacquiring or learning new words while reading a text is an important practicalmethod of vocabulary enlargement，the availability of authentic materials on theInternet and the access of electronic dictionaries provide two helpful conditions forlearners to learn vocabulary．First，the World Wide Web is not only one of themost efficient channels for global communication but also a huge and abundantlanguage—learning source for EFL learners．Second，electronic dictionaries appearwith computer technology combined with dictionary information．Integrated withcomputer technology，dictionaries assume more importance for text comprehensionand vocabulary learning with its technical benefits．
