高中教師專業認同對專業成長影響之多群組樣本分析：以參與專業學習社群為中介變項

A Multi-Group Sample Analysis of The Impact of High School Teachers' Professional Identity on Professional Growth: Using Participation in Professional Learning Communities as A Mediating Variable

本研究從社會認同理論為論述基礎，從專業認同以及參與專業學習社群兩方面來探討對專業成長的直接影響，並且以專業學習社群的參與為中介變項。除此之外，本研究也分析上述的變項關係在不同年資、社群類型的差異情形。本研究以656位參與專業學習社群的高中教師為對象，採用的分析方法為結構方程模式的適配度分析以及多群組分析。本研究發現，專業認同對專業學習社群有直接效果，專業學習社群對專業成長有直接效果，且專業認同可以透過專業學習社群參與的中介對專業成長產生間接效果。而這樣的模式關係，在多群組分析後亦獲得相同的結果，也就是說，不論是基礎社群、學習社群或是高、低年資社群，都是這樣的模式關係，並且進一步的回歸係數比較分析顯示，低年資的教師專業認同對於專業學習社群的影響將大於高年資的教師。

Based on Social Cognition Theory and System Dynamics, this study explores the direct impact on professional development from the perspectives of professional identity and participation in professional learning communities, and professional learning communities is taken as a mediating variable between the relationship of profession identity and professional development. In addition, the difference of the above variable relationships in different seniority and community types are also analyzed in this study. There are 656 senior high school teachers who participated in professional learning communities as the study object, and the analysis methods adopted were the structural equation model fit analysis and multi-group analysis. This study found that professional identity makes a direct effect on professional learning community, professional learning community makes direct effect on professional development, and professional identity can make an indirect effect on professional development through the mediation of professional learning community participation. And such relationship pattern makes same results as obtained after multigroup analysis. That is to say, whether it is a basic community, it makes similar model relationship in a learning community or a senior or junior community. Further comparative analysis of regression coefficients shows that the impact of junior teachers’professional identity on professional learning community will be greater than the seniors.
