本研究旨在探討用溝通式教學法所編寫之教科書對高中英文教師教學實務之影響，並試圖了解高中英文教師教學實務是否符合教育部頒布的高中英文教學要領。 本研究以問卷調查方式進行，對象為大高雄地區(高雄縣市)21所高中的254位高中英文教師，共計回收問卷205份，回收率為80.7%。問卷內容改編自Littlewood (1981)溝通模式及教育部頒布的高中英文教學要領。 本研究主要結果摘要如下： 1. 部份符合溝通式教學法的項目為授課語言、文法教學、課堂時間分配及溝通式活動等四項。 2. 多數高中老師花最多課堂時間在講授課程，練習活動次之，最少時間於英文說寫活動。 3. 多數高中老師的課堂活動主要為溝通前之練習，而非溝通式活動。 4. 老師的教學實務包括聽力、口說、閱讀及寫作較符合溝通式教學法之精神。 5. 和男性教師相較之下，女性教師的教學較符合高中英文教學要領且和溝通式教學法有正相關。此外，和未修過TESOL教師相較之下，修過TESOL之教師的教學也和溝通式教學法有正相關。 根據問卷調查結果，本研究最後提供相關建議以供參考。 / The major purpose of this study is to know how English teachers conduct teaching activities concerning four skills in their classes with CLT-based textbooks. In spite of the popularity and prevalence of CLT approach, it is by no means applied and practiced without any impediments or constraints. In actual teaching practice, there exist a variety of differences for senior high school English teachers when conducting teaching activities with CLT-based textbooks. In this study, the focus will be on senior high school English teachers’ teaching practices with CLT-based textbooks in greater Kaohsiung area. In addition, the consistency of teachers’ classroom practices and the Instruction Guidelines is examined as well. The 254 participants selected in this study were English teachers from 21 different senior high schools in greater Kaohsiung area. 205 questionnaires were collected from the targeted 254 respondents, yielding a return rate of 80.7%. The questions in the questionnaires were mainly adapted from the communicativeness model of Littlewood (1981) and the Instruction Guidelines issued by the Ministry of Education. The major findings are summarized as follows: 1. Instruction language, grammar teaching, classroom time for PPP and the communicativeness of activities conformed only partially to the creed of CLT. 2. Senior high school English teachers spent most of the classroom time for presentation, less time for practice, and least time for production. 3. Most teachers’ classroom activities were mainly pre-communicative activities, instead of communicative ones. 4. Teachers’ teaching practices, including listening, speaking, reading and writing, are consistent with the core of CLT. 5. Female senior high school teachers conform more to the Instruction Guidelines and correlated more positively in classroom practices than male teachers. Besides gender, teachers who had taken TESOL-related courses before correlated more positively in classroom practices than those who did not. Based on the findings, some suggestions have been made for pedagogical implications and further studies. The limitations of the study are mentioned as well.
