英語口說表現與字彙量、搭配詞知識及成語知識之關係研究

The Relationship of EFL Learners’ Vocabulary Knowledge to Their Speaking Performance: Productive Vocabulary Size， Collocational Knowledge and Idiomatic Knowledge

本研究旨在探討臺灣英語學習者的口說表現與字彙量、搭配詞、成語知識的關係。本研究主要回答以下三個研究問題：一、字彙量知識與口說表現的相關程度為何？二、搭配詞知識與口說表現的相關程度為何？三、成語知識與口說表現的相關程度為何？研究對象為就讀或畢業於北臺灣英語相關系所的32位碩士生。研究工具包含五項測驗：一、字彙量測驗；二、搭配詞測驗；三、成語測驗；四、影片口語測驗；五、雅思口語測驗。資料分析的工具則採用基本敘述統計、皮爾森相關係數。研究結果顯示英語所碩士生的口說表現與字彙量知識及成語知識的相關性為顯著正相關。但搭配詞知識與口說表現之間卻沒有顯著關聯。另外受試者使用搭配詞知識和成語知識也沒有和口說表現呈顯著關聯。針對於本研究的結果，本研究最後提供對英語教學之應用，以及對未來研究的建議。

This purpose of the study was to investigate the relationship of Taiwanese learners’ English speaking performance (ESP) to their performance on each of three vocabulary knowledge subcomponents. Specifically， the study aimed at answering the following three research questions: (1) What is the relationship of ESP to productive vocabulary size (PVS)? (2) What is the relationship of ESP to lexical collocational knowledge (LCK) and to actual use of lexical collocational knowledge (AULCK)? (3) What is the relationship of ESP to idiomatic knowledge (IK) and to actual use of idiomatic knowledge (AUIK)? A total of 32 graduate students from two universities in northern Taiwan participated in the current study. Five instruments were employed， including (1) one productive vocabulary levels test， (2) one lexical collocation test， (3) one idiom test， and (4) two speaking tests. The collected data were analyzed through Pearson correlation procedures. The results of the present study showed that ESP was significantly and moderately related to PVS and to IK. However， no significant correlation was found between ESP and LCK. Neither was there any significant relationship found between ESP and AULCK， and between ESP and AUIK. Based on these findings， some implications and suggestions for future research were provided.
