本文的主要目的在探究行動研究中的「核心研究者」宜扮演何種角色的問題。方法上，主要是透過一個教育行動研究之規劃、行動、參與、觀察及反省的過程以及對此研究的再反省來達成。 經由上述的行動研究與對該研究的再反省，本文認為行動研究的參與成員若對行動研究缺乏認識，核心研究者宜從「引導者」的角色切入。在引導的方向上，包含：1.協助成員掌握行動研究的相關概念；2.讓成員共同發展行動研究的相關概念；3.促使行動研究團隊順利且有效的運作。在針對這些方向引導時的引導方式，本文則分別從引導的方法與態度反省筆者在上述行動研究中的做法。最後，本文建議有志於行動研究者在從事行動研究之前須衡量自身是否扮演「核心研究者」的角色，若是的話則宜從「引導者」的角色切入，至於「引導的方向」與「引導的方式」（包含引導的態度與方向）則可參考本文所提出來的觀點。

　　　　　The main purpose of this article is to explore how should the core researcher play his role in an action research? An educational action research and the reflection on it are adopted to reach the purpose. First of all, the article thinks that the core researcher had better be a guide if participants lacking in knowledge concerned with action research. Next, it shows three dimensions of guidance as follows: 1. Trying to help those taking part in action research to understand some concepts concerned with action research. 2. Trying to facilitate those participants to co-construct some new viewpoints about action research. 3. Trying to strengthen and improve the operation of action research. Thirdly, the article tries to reflect the author’s ways of guidance before. Attitudes and methods adopted by the author himself are the focus of reflection. Finally, the article suggests that the core researcher of an action research may guide the other participants according to the “the dimensions of guidance” and “the ways of guidance” proposed by this article.
