Recently, organizational culture in school is changing as the way people perceive surroundings
and behave themselves has changed. It is pointed out in a large number of papers that
organizational culture in school needs to change in a certain direction. However evidence for the
nature of changing organizational culture is scarcely found.
I tried to demonstrate the change in the organizational culture, composed of collaboration,
participation in decision-making, and discussion with the colleagues, and the influential factors on
that, especially supportive leadership, examining the data of the middle schools surveyed at 4
times from 2004 to 2013 by KEDI. The softwares I employed were IBM SPSS Statistics ver.22
which was very helpful to handle huge amounts of data, and HLM 7 for Windows which made
it possible to analyze the data on three levels: individual, organization and time. The variation in
changing collaborative culture of middle school was verified by MANOVA. Also, HLM
substantiated some key factors influencing on the variation.
The result is, firstly collaborative organizational culture of middle school has changed during
the last decade. Second, the longer the teachers worked, the stronger the collaborative
organizational culture of the teachers was. Third, collaborative organizational culture of middle
schools which had strong organizational culture at beginning point changed less. Lastly, it is
possible that supportive leadership was a undermining factor at the organizational level even
though it made organizational culture stronger at the individual level. More in-depth studies are
needed to capture changing organizational culture.
