本研究旨在探討臺北市立高級中學教師組織運作成效。其中教師組織主要是指「學校教師會」，運作成效則包含「強化組織運作」、「促進校園民主」、「提升教師專業」等三個層面；並分析「強化組織運作」、「促進校園民主」與「提升教師專業」三層面間的相關程度；進而利用開放問卷了解學校教師對未來教師組織發展的期待與展望。 研究採問卷調查法，對象為臺北市立高級中學編制內正式教師，問卷共寄出400份，回收326份，回收率81.5％，剔除無效問卷25份，尚餘有效問卷共301份。在統計上採用次數分配、平均數、標準差、t考驗、單因子變異數分析與積差相關，並就單因子變異數分析呈現差異者再以薛費法或LSD法來進行事後比較。最後根據文獻探討、問卷調查與開放問卷結果，歸納結論如下： 一、「學校教師會運作成效」屬中高程度，「強化組織運作」、「促進校園民主」層面屬高程度，「提升教師專業」層面屬中高程度。 二、各背景變項對「學校教師會運作成效」，在高中校史較短與較悠久、男性、任教年資較淺、曾兼任學校行政職務教師高於一般教師。 三、各背景變項對「強化組織運作」層面運作成效，在任教年資較淺、曾兼任學校行政職務教師高於一般教師。 四、各背景變項對「促進校園民主」層面運作成效，在高中校史較短、男性、任教年資較淺、曾兼任學校行政職務教師高於一般教師。 五、各背景變項對「提升教師專業」層面運作成效，在普通高中、高中校史悠久、任教年資較淺、曾兼任學校行政職務教師高於一般教師。 六、「強化組織運作」、「促進校園民主」與「提升教師專業」三層面間達相關性顯著且為高度正相關，各面向間亦達相關性顯著且為高度或中度正相關。 七、高中教師期待未來教師組織能參與教育政策制定、強化教師組織運作、提升教師專業素養，在不影響學生受教權的前提下，積極爭取教師權益。 最後，根據上述研究結論提出建議，供學校教師組織及其他研究者參考。 關鍵詞：學校教師會、教師工會、教師組織運作成效 / The purpose of this study is to investigate the operational effectiveness of high school teachers organizations in Taipei.
