This handbook was developed to provide managers working with the National Science Foundation (NSF) with a basic guide for the evaluation of NSF's educational programs. It is aimed at people who need to learn more about what evaluation can do and how to do an evaluation rather than those who already have a solid base of experience in the field. This handbook builds on firmly established principles, blending technical knowledge and common sense to meet the special needs of NSF and its stakeholders. Quantitative and qualitative evaluation methods are discussed, suggesting ways in which they can be used as complements in an evaluation strategy. As a result of reading this handbook, it is expected that program managers will increase their understanding of the evaluation process and NSF's requirements for evaluation as well as gain knowledge that will help them communicate with evaluators and manage the actual evaluation. Several NSF program areas were selected to provide concrete examples of the evaluation issues discussed. The handbook is divided into four major sections: (1) "Evaluation and Types of Evaluation"; (2) "The Steps in Doing an Evaluation"; (3) "An Overview of Quantitative and Qualitative Data Collection Methods"; and (4) "Strategies That Address Culturally Responsive Evaluation." A glossary of commonly used terms, references for additional readings, and an appendix that presents some tips for finding an evaluator are also included. (MM)
