Kurzinfo: The quality criteria described above grew out of the results of a comparative research study on quality criteria, and a comprehensive report is now available. This report is based on information collected from 13 country reports on implicit and explicit criteria guiding Eco-schools′ development processes in whole school plans, inspired by Environmental Education values and principles. By analysing trends and divergences in the reports, the publication will focus on identifying the visions of the future world that are embedded in the Eco-schools′ programmes and what conceptualisation of learning-teaching processes and school development can be identified in this work.
