This study is amis to reinterpret about the teacher’s reflection in the light of Vipassana’s sati(mindfulness). In spite of teacher’s reflection’s importance, the concept of teacher’s reflection has been mislead and so it has been misunderstood in the field of teacher’s education. If the teacher educators willing to approach to reflection in Vipassana, what the idea of reflection been in their mind have to be reversed. In general the concept of reflection has been understood in the light to reflective thinking which be written by Dewey’s research. But the reflection in the reflective practice is not similar to reflective thinking in generally speaking. In general terms, the process of reflective thinking includes the working of logics and reasoning in contrast of the process of teacher’s reflection. And so the teacher’s reflection might be discussed in the base of teacher’s present implementing by behaviors. Because of the present momentum of teacher’s behavior, it is no places of the implementing of logics and reasoning in teacher’s reflection The essential meaning of teacher’s reflection is based on the concept of reflection-in-action which suggested by Schőn. The reflection-in-action could be explained that the two functions of reflection and action perform simultaneously in the practice of teacher’s behavior. In the light of special terms of teacher’s reflection, teacher’s reflection could be discussed by Vipassana sati(mindfulness). The sati(mindfulness) is the power of successfully observing the state of mind and body. As well as reflection, the momentum of behavior is also important factor in Vipassana’s asceticism. In this view this, this study compares teacher’s reflection with sati and teacher’s reflection reinterpret in the view of Vipassana. In the way of this, the enhancing methods of the power of teacher’s reflective practice are going to be pursued.
