Part 1 of this monograph discusses the status of educational evaluation and describes several problems in carrying out such evaluation: (1) defining the educational setting, (2) defining decision types, (3) designing educational evaluation, (4) designing evaluation systems, and (5) defining criteria for judging evaluation. Part 2 proposes an approach to educational evaluation which would alleviate problems of definition and design. Different types of decision settings and appropriate evaluation strategies are explored. Types of decisions are matched with types of evaluation. The structure of evaluation design including the collection, organization, analysis, and reporting of information is outlined. Finally, criteria for judging evaluations such as validity, reliability, significance, scope, and efficiency are presented. Figures are given, including the CIPP (context, input, process, and product) Evaluation Model. (AL)
