本研究旨在探討我國國民中學教師知覺領導者—成員交換關係、教師工作滿意度與教師離職傾向之實際情形，並瞭解領導者—成員交換關係對教師離職傾向的影響以及研究教師工作滿意度是否具有中介效果。 研究方法為文獻分析與問卷調查法。研究對象為桃園縣國民中學教師，共發出450份問卷，可用問卷共383份，可用率達85.11％。問卷回收後分別以因素分析、信度分析、描述性統計、t考驗、單因子變異數分析、Pearson積差相關、多元逐步迴歸及逐步階層迴歸分析等統計方法進行研究。根據研究結果與分析後歸納之結論如下： 一、桃園縣國民中學教師知覺領導者—成員交換關係為中等程度，以「情感」之知覺程度為最高，「貢獻」之知覺程度最低。 二、桃園縣國民中學教師在工作滿意的知覺為中等程度，以「自我實現」的知覺為最高，「工作壓力」之知覺為最低。 三、桃園縣國民中學教師在離職傾向的知覺現況為低程度。 四、不同背景變項的桃園縣國民中學教師知覺領導者—成員交換關係、教師工作滿意度與教師離職傾向的程度有差異。 五、桃園縣國民中學教師領導者—成員交換關係、教師工作滿意度與教師離職傾向的知覺，彼此間具有顯著相關。 六、領導者—成員交換關係與教師工作滿意度對教師離職傾向有顯著的聯合預測力，其中以「同僚關係」的預測力最高。 七、教師工作滿意度在領導者—成員交換關係對教師離職傾向的影響上具有中介效果。 最後，根據研究結果提出建議，以供教育行政機關、國民中學學校校長、教師及後續研究之參考。 / This study aims to investigate the current development of the junior high school leader-member exchange, teacher job satisfaction, and teacher turnover intention in Taoyuan County, and to discuss the influ- ence of leader-member exchange and teacher job satisfaction on teacher turnover intention and to test whether teacher job satisfaction is a signi- ficant mediator or not. The research process combines literature review and questionnaire method. Teachers in Taoyuan County public schools are the main survey subjects. Totally 450 questionnaires were distributed to schools, and 383 are valid, which the amount of usefulness is around 85.11%. The data is analyzed through the statistics method of factor analysis, reliability analy- sis, descriptive statistics, t-test, one-way ANOVA, Pearson product- moment correlation coefficient, multiple stepwise regression analysis and stepwise heirarchical regression analysis. The findings of the study are follows: 1. Teachers in Taoyuan County public schools show median level of perception in leader-member exchange while “affect” is the highest, and “contribution” is the lowest. 2. Teachers in Taoyuan County public schools show median level of perception in teacher job satisfaction while “self-actualization” is the highest, and “work intensity/load” is the lowest. 3. Teachers in Taoyuan County public schools show low level of perception in teacher turnover intention. 4. Teachers with different background show different opinions in leader-member exchange, teacher job satisfaction, and teacher turnover intention. 5. The relations among leader-member exchange, teacher job satisfaction, and teacher turnover intention are significant. 6. Leader-member exchange and teacher job satisfaction show significant predictability to teacher turnover intention while “colleague relationship” is the highest. 7. Teacher job satisfaction functions as a significant mediator between leader-member exchange and teacher turnover intention. According to the above conclusions, the research proposed relevant suggestions to be referenced by education administrative organizations, junior high school principals and teachers, and future researches.
