Evaluating Environmental Education provides an in-depth look at conducting an evaluation. For each step of the process (e.g. formulating objectives, selecting instruments, collecting data, etc.), the guide provides clear explanations of the choices an evaluator has as well as important factors to consider when choosing among options. Numerous examples are used throughout to make the concepts more concrete.
