Two modern crises--in education and ecology--can both be alleviated by adopting an "environmental classroom"; that is, by moving from the traditional schoolroom to closer contact with the world outside. The first part of the volume examines traditional approaches to education and them moves step by step to innovative ones, such as using the urban environment as an educational problem setting and using real environments outside the school. The second section includes reading selections meant to stimulate thought about the environment and educational alternatives. These selections are by authors like Margaret Mead and Ivan Illich. (JK)
