Actions and practice architectures for realising sustainable development by restructuring school organisations

Sustainability is increasingly being understood as vital for school improvement. The objective of this study is to expand our knowledge of practice architectures that enable and constrain the realisation of sustainable development by restructuring school organisations to facilitate professional learning. In this follow-up study, we return to one of the three municipalities that were involved in an earlier project from 2009 to 2011. The theory of practice architectures is used as an analytic tool to identify and analyse actions that have an impact on the municipality’s efforts to realise sustainable school improvement. The results reveal dissimilarities between the investigated municipality’s school organisation and the preschool organisation. In the case of the school organisation, the dominating practice architectures disrupt the realisation of sustainable development, while in the case of the preschool organisation they are continuous and foster the same. One disruptive practice architecture in the school organisation is the idea of the autonomous principal, which disturbs the progression of a distributed leadership. In the preschool organisation, the superintendents are crucial for facilitating participation in professional learning.

Multiple Case

This multiple case study examined three Midwestern elementary schools identified as having successfully implemented professional learning communities for many years. From the data, themes emerged indicating that there are key distributive components to successful leadership in implementation of the school improvement initiative. The findings in this study demonstrate that successful leaders create a collaborative culture, seek shared leadership and decision-making practices and have a narrow focus on student learning. Implications for principals and leadership preparatory programs are significant.

Main Components

Scanning microscopy was used to study the surface of human gallstones and the surface of fractures. The specimens were obtained by operation, washed with water, dried at room temperature and shadowcasted with carbon and aluminum. Most of the specimens belong to patients from a series of X-ray follow-up study, examined during the last twenty years. So it was possible to evaluate approximately the age of these gallstones and to get information on the intensity of growing and solving.Cholesterol, a group of bile pigment substances and different salts of calcium, are the main components of human gallstones. By X-ray diffraction technique, infra-red spectroscopy and by chemical analysis it was demonstrated that all three components can be found in any gallstone. In the presence of water cholesterol crystallizes in pane-like plates of the triclinic crystal system.
