本教學實驗旨在探討如何教導國中生認識英語弱化音。筆者身為英語母語人士經常看到即使有十年或二十年學習經驗的英語學習者，仍舊無法完整了解母語人士講述的內容，原因就是弱化音與連音所造成的困擾，本研究藉著教導學生具備相關辨識能力，希望了解學生對這樣學習的成果與反應。 研究首先施行前測，取得比較基準，接著設計並在課堂實施了七個節次的教學，包括四堂連音、三堂弱化母音。課後再施行後測。前後測比較之下並無顯著統計差異。但是針對學生所作的問卷調查發現，學生覺得學到了聽力技巧與能力有所進步。此外協同教師在訪談中也表示，此教學對學生的聽力技巧與能力有所助益。 根據本次研究經驗，筆者提出教學建議，認為教授國中生弱化音與連音確有必要，也期待這樣的教學應該盡早提供，而非等到高中或大學，以免為時已晚。 / This study looks at teaching reduced sounds to junior high school students. It started with the premise that even people who have studied English for ten or twelve years still cannot understand online materials spoken by native speakers of English. The reduced sounds and linked sounds baffle them. This study investigated the student reaction to hearing reduced vowels. A pretest was administered to establish a baseline. Four contractions and three reduced vowels were presented in the lessons. Then a post-test was given. The statistics showed no measurable change between pretest and post-test scores. However there are other ways to measure progress. In the survey given with the post-test, a number of students responded that they felt they had learned listening skills, and that their listening comprehension had improved. There were also interviews with co-teachers. These interviews also bore out that teachers felt the students’ listening comprehension had improved. The writer, as an active participant in the study, feels that teaching reduced sounds in junior high school is worthwhile. One should present more reduced sounds and linked words early on, and not wait until senior high school or university.
