本研究整理出反思教學的四個特性:一、分析行動過程以達成目的 (analyzing practices and achieving ends);二、收集教學所需的資料 (collecting teaching data);三、計畫及實際行動和評估教學行動 (planning, implementing and evaluating teaching action);四、反思必需不斷練習 (cyclic reflection)。依據反思教學的特性以及有助於反思的理念設計CurriculumTree3.0系統功能,提供六大功能模組:課程管理模組 (curriculum management module)、教學教材管理模組 (teaching material management module)、教學活動管理模組(teaching activity management module)、教學計畫管理模組(teaching plan management module)、反思教學模組(reflective teaching module)、學生歷程管理模組(students profile management module)。以CurriculumTree3.0系統做為教師反思的工具,並設計反思教學的實驗模式,進行六至八週的實驗過程,最後以反思的四個層次思考習慣 (habitual Action)、對教學的了解程度 (understanding)、教學反思 (reflection)以及批判性反思 (critical reflection)探討教師的反思情形。研究結果系統有助老師掌握並了解教師本身的教學方式,並且讓老師可以檢視並反思自己的教學實務,有助於老師獲得批判性思考的教學。 In this paper, I consider four points about reflective teaching: (1) analyzing practice and achieving ends, (2) collecting teaching data, (3) planning, implementing and evaluating teaching action, (4)cyclic reflection. According reflective teaching and related theory, I design six system modules of CurriculumTree V3.0 : Curriculum management module, Teaching material management module, Teaching activity management module, Teaching plan management module,.and Reflective teaching module, Students profile management module. By using CurriculumTree3.0 system tool to help teachers obtaining reflection and use the reflection teaching experiment model to do six to eight weeks experiment. At the end, the paper discusses about the result of teacher’s reflection by four-reflection levels: Habitual Action, Understanding, Reflection, and Critical reflection. The conclusion of the study is that CurriculumTree V3.0 can have the initiative of teachers’ hands in their teaching method and reflect oneself. By doing so, it can help teacher to acquire critical thinking in their teaching.
