I assume you mean tertiary education, but just in case it is of interest, I will put forward my opinion concerning secondary schools. In Australia, secondary schools have a workplace culture that is unlike most other workplaces. They are more like committees with factions than a boss/employee situation, so change is a much more complex process since it usually has groups for and groups against and groups who couldn't care less about the change. In some ways that makes Kaizen more useful. Focussing on informal methods for determining change in a type of action research process, creates a group mindset of acceptance of change, albeit over different timeframes. Everybody is involved and sharing with everybody else their ideas and via the action research, ideas that result in improvement are adopted, slowly but surely. It is far more effective than top down changes that only really ensure superficial acceptance.
