Think globally, act locally, plan (Also) centrally

When an environmental studies curriculum was developed for senior high schools in Israel, special attention was paid to the methodological approach, to content selection, and to the integration of central and school-based curriculum strategies. While central curriculum teams usually have an advantage in their better access to budgets, to specialized sources of information, and to central examination bodies, local teachers are those who best can develop a curriculum unit based on a real, environmental problem, toward which students can actively contribute a solution. A model is described, which was used to optimize the contribution of both central and school-based curriculum teams. The main implementation problems located were the need to identify local sources of knowledge and the need to train teachers in choosing modular curriculum units, in working with groups on a realistic project, and in project evaluation.
