This booklet is one in a series of resource manuals to help teacher educators conduct environmental education (EE) teacher workshops or promote EE programs. This unit is an orientation to the field of EE. It offers a definition of EE and some ways to explain its value to educators and environmental managers. The unit explains current and historical notions of what children need to learn and how they can be taught if they are to become environmental problem solvers. The unit is presented in six sections that describe: (1) the essence of EE; (2) the value of EE; (3) the evolution of EE from the classic interpretation to the contemporary view of EE; (4) current EE issues in the school; (5) activities and masters for teaching the unit; and (6) a list of 14 resources. The activities make up the majority of the booklet and offer suggestions to help teacher educators conduct workshops that give teachers an understanding of the objectives of EE and how these might be translated into the curricula.
