In this study, it is aimed to reveal the educational beliefs that the changes in the physical appearance of schools in the context of Althusser's ideological apparatuses will reveal in teachers. Thirty-eight teachers working in different provinces of Turkey and working in different branches participated in the study. Semi-structured interviews consisting of seven basic questions were conducted with the teachers. Qualitative data were analysed through phenomenographic analysis. From the data, three categories for the explanatory category of "educational practice" in terms of educational beliefs and three categories for ways of description, two categories for the explanatory category of "teacher practice" in terms of educational beliefs and two categories for ways of description, three categories for the explanatory category of "power practice" in terms of educational beliefs and three categories for ways of description were obtained. This study shows the educational beliefs revealed in teachers in terms of three parameters (education, teacher, power) selected in the context of Althusser's ideological apparatuses. It is thought that the findings obtained will help us to see the changes that may occur in teachers' educational beliefs as a result of changes in the physical appearance of schools.
