Designing evaluations of educational and social programs

Designing an evaluation is rather an art, as each must be designed according to its appropriateness to the situation being evaluated. The advantages of each feature of the design must be balanced against any sacrifices each of these choices entail. Designers must plan for the allocation of investigative resources, selecting investigative questions that are most apt, and be aware of both practical and political considerations. This volume includes both new approaches to the design of educational evaluations, and discusses the pros and cons of frequently used design concepts.
