本文探討運動教練訓練知識之來源，首先以知識擷取和社群參與的觀點論述教練教育學理基礎，認為學習的產生需仰賴兩者間的互補建立認知結構；其次以正規、非正規與非正式教練教育類別分析知識來源，發現非正式學習可能是影響教練知識的重要來源，如師徒制、訓練實戰經驗或觀摩他人等的互動學習，以及網路資訊、教練專業社群等多元管道的補充學習皆為教練豐富的知識庫，故以社會互動共構知識的概念輔助正規教育可視為教練培育重要的一環。建議未來可依此架構發展，對我國教練議題進行系統性研究，作為相關單位培育規劃與課程開設方向之參考。

This paper investigates the sources of coaching knowledge of athletic coaches. It starts with discussing the theoretical foundation of coach education from the perspectives of knowledge capture and community participation, it is concluded that the learning outcomes need the complementary interaction of the two to construct a cognitive structure. This is then followed by an analysis of the sources of knowledge based on different types of coach education, meaning formal, non-formal, and informal coach education. It is found that an important source influencing the knowledge of coaches is informal learning, including interactive learning methods like mentoring, combat exercises, or learning by observing others, as well as the supplementary learning methods through multiple channels like the Internet and professional communities of coaches are rich knowledge banks for coaches. Therefore, it is important to utilize both formal education and social interaction in the knowledge forming process of coach education. It is recommended that systematic studies of the issues concerning local coaches to be conducted in the future take account of this framework to serve as a reference for related units in terms of the directions for education and curriculum planning.
