A manual for trainers of development workers and change agents in the third world provides guidelines for evaluation of development training programs. Chapters define evaluation, present a general model of development, and discuss evaluation in development training programs. Designing training systems for development workers and change agents, asking evaluation questions, making evaluation agendas, writing formal proposals for evaluation studies, and monitoring and quick appraisals are covered in subsequent chapters. Naturalistic and scientific paradigms of evaluation, concept analysis, change indicators, quality standards, and evaluation tools and instruments are discussed. Other chapters detail product evaluation (pre-testing of instructional and training materials), designing evaluation studies, and the concept of design in naturalistic evaluation. Implementing evaluation studies is discussed in connection with problems of data collection in the real world. Processes and techniques of data analysis and statistics for evaluators of development training programs are covered. Guidelines for writing evaluation reports are given. A final chapter discusses politics of evaluation and evaluation standards. An appendix covers history and use of the Action Training Model. A bibliography presents sections on training design (26 entries), evaluation models and techniques (65), and evaluation of training and development (31). A glossary defines relevant terms. (MH)
