本文探究邁克.桑德爾之開放教育的理念、實踐與影響及其對教育的啟示。桑德爾的開放教育已影響了百萬人、獲得許多獎項而可以成為典範。藉由文獻分析及參與桑德爾線上課程來分析課程文本、影片、桑德爾的著作與相關論述。從中研究發現桑德爾的開放教育之理念為對自由主義價值空虛之不滿而提倡公開對重要議題的論辯,其實踐為創設正義的課程網站及在磨課師上傳播,其影響是創造了免費全民參與的世界教室並激勵了教師與學生。五項啟示為:一個人的理想必需引導實踐的方向、一個成功的傳統課程加上開放教育的特色可構成一個成功的開放教育課程、透過開放教育可放大教師的影響力、混合模式可取代一體適用的模式、透過課程的開放可實現知識分子的社會責任。
The paper explores the ideas, practices, and influences of Michael J. Sandel's open education and infers some implications for education. Sandel's course of "Justice" has influenced millions of people, received awards, and can serve as a model. Through literature review and participation in Sandel's online course, the study analyzes the course readings, videos, Sandel's works, and related arguments. The findings are as follows: The ideas of Sandel's open education are discontented with the liberal's value vacancy and proclaiming the debate of the big questions in public, the practices are creating the course website of "Justice" and spreading it in MOOCs, and the influences are creating a world-class education free and for all and inspiring the teachers and students. Five implications are: One's ideals must guide the direction of practice, a successful traditional course with the features of open education could form a successful open educational course, open education can be used to amplify a teacher's influence, the one-size-fit-all model should be replaced with blended models, and opening a teacher's course online can fulfill the social responsibility of intellectuals.
