本篇論文為發掘指導臺灣日語學習者提升日語口語表達技能的方法，特別針對學習者自身意識到口語表達的問題與其實際發話的問題點做一剖析。以143名日語專攻中階程度的大學生為對象，施予開放式問卷調查後發現，其特別感到困擾的項目有「表達的基本功」、「表達的正確度」、「語彙能力的不足」3項。然而，再將此143名中40名學習者的實際發話加以分析後，則可抽取出10大問題點。藉由此次的分析結果可知：指導台灣學習者日語口語表達時，除了語句的正確性與基本功之傳授之外，亦應多督促其注重實際的表達技巧面。

This article looked into intermediate level Taiwanese learners' awareness about and performance of oral interact ion in order to obtain suggestions for helping them to acquire advanced skills of speaking Japanese. An open-end questionnaire survey was conducted for 143 Japanese learners who were registered in intermediate level courses at a department of Japanese about problems they felt they had in speaking; it revealed that the learners were most concerned about lack of accuracy, limited size of vocabulary, and lack of knowledge of appropriate expressions. Interviews were given to 40 learners and their utterances were analyzed, and actual problems turned out to be related to skills of conducting interactions rather than to knowledge or accuracy. Thus, instructions for these intermediate learners should promote their awareness on importance of interactive skills.
