本文探討了教育研究中課堂觀察法的觀察偏差問題，並以體育課為案例說明。本文認為，此問題的產生，源自於觀察者本身的因素，與觀察者和被觀察者之互動所造成的因素。而處理觀察偏差問題的方法，除了從觀察者本身的能力著手外，還可以從內在和外在兩個方面來改善觀察法的觀察偏差問題。最後並提出全面認識觀察偏差的可能、盡力處理觀察偏差的問題、然後詳盡說明觀察偏差的情況，是處理教育研究中課堂觀察法的觀察偏差問題時，可以思考的路徑，以作為日後使用此研究方法的參考。

The purpose of this study was to investigate the deviations of classroom observation in research of education and cases from physical education.The observer himself might be the factor which lead to this problem, as well as the interactions between the observer and the observed. Methods to dispose the deviations were applied, which could start from the ability of the observer, inner and outer aspects to solve the deviations of classroom observation were also operable. Possibilities to understand the observe deviations were offered, to solve this problem, then to explain it in detail, was also a way of thinking to dispose the deviation problems of classroom observation in research of education.
