Book excerpt: Abstract: Prepared as a guide and handbook for planners, developers, and evaluators of educational programs and products, practical insights are given on planning and executing effective evaluations. The evaluator's work is viewed as establishing perspective, planning the evaluation, and analyzing the data. Procedures that are appropriate for each of these activities are identified for the reader. The subject matter in this multiauthored book is divided into roles and contexts, models and strategies, and methods and techniques. Contributors also depict today's standards for evaluation and project what those standards will be in the future.
