RESPOND glossary

Teacher professional development and school development as a profes sional learning environment are all about change, including even changes in the paradigms that are referred to during the process. According to Kuhn (1962), any transition from one paradigm of reference to another requires the search both for new lexis and for new definitions of existing lexis. This can lead to terminological confusion, which involves both existing and new sig nifiers and signifieds. This confusion is not necessarily negative but is rather a reorganization of relationships and a redefinition of meanings that are nat urally part of the new conceptualization (Dodman, 2016). The following RE SPOND glossary offers definitions of many key terms used in this volume that we believe are central to building a paradigm for sustainable develop ment.
