Abstract
Recent debates on education for sustainable development suggest a paradigm shift, exploration of which is just beginning. Discussions are often concerned with how differing curricular elements could be combined and different media used to capture complex character of environment.
Educational toolkits that provide systematic ground for environmental and SD studies are designed in a dialogue between different ""language games"" that provide opportinity to critically overveiw different discourses. Environmental and SD aspects related to the complex character of reality can be an agent of change in the use of knowledge sets in educational systems.
The aim of ESD project under Czech conditions was to design a toolkit for university teachers, students of pedagogical faculties enrolled in programs for upper primary and secondary grades, and for involved/interested general public.
