Abstract
The present study surveyed the current status of investigation in schools that makesteachers confirm their own everyday educational practice, and considered what pointsshould be investigated in terms of the way educational practice is carried out by teachersand what kind of competencies should be improved. The results suggest the possibilitythat investigations in schools have only been carried out in the frame of a culture thatschool teachers had developed and shared, and were limited to pursuing teachers' image ofan “ideal practice”. Therefore, investigations in schools were far from realistic and henceunable to cue a fundamental reconsideration of the state of educational practice. Theresults also suggest that investigations in schools have become a kind of routine work, focusing on issues that are separate from teachers' everyday educational practice. Thusit was discussed that the understanding and treatment of the frame of practice should bethe competence expected of teachers, and that the next step should be the re-establishment of the settings of investigation in schools.
