本研究旨在探討及分析初中體育教師應用「自我評鑑」方法於教學回饋上之影響，研究對象為本地二十位初中體育教師，利用錄像器材，先後共兩次拍攝各受試者進行體育課教學的情況。結果顯示，實驗組在經過觀察、認知、討論及自我評鑑的過程後，在教學回饋的應用上明顯地較對照組獲得進步，對本身的教學行為亦有更客觀的認識。研究結果鼓勵體育教師應用錄像器材，定期自我拍攝教學過程，透過客觀的分析方法，檢討及評估自身的教學效能。有關職前及在職師資培訓的課程，亦應加強學員在教學上自我評鑑的訓練及應用。

　　　　　The purpose of this study is to examine the effects of a self-assessment feedback intervention among junior secondary physical education teachers. Data were collected by videotaping twenty physical educators during their natural and usual setting physical education lessons. The Self-Assessment Feedback Instrument (SAFI) was used to examine the teaching behaviors. Results indicated that self-assessment feedback intervention was effective in improving and increasing teaching behaviors including praise, praise/reinstruct, and questioning. Regardless of teaching experience, teachers who were obliged to a self-evaluation practice, modified their teaching strategies accordingly. Having teachers analyse tapes of their own instruction using SAFI as well as attending feedback intervention was proved to be effective and less threatening than using other means such as peer evaluation. Selfassessment instrument is one of the most effective ways to improve teacher effectiveness, therefore, such practice should be emphasised and implemented systematically for both in-service and pre-service physical educators to help them to become reflective practitioners.
