In this paper, the author talks about some recent developments in the methodology of program evaluation and about what he calls "responsive evaluation." He discusses two models for program evaluation, namely (1) informal study or self-study; and (2) the pretest/posttest model. Then, he describes an approach that he has been working on, which will challenge the two major models, and mentions several relatively recent developments in the evaluation business. To be of service and to emphasize evaluation issues that are important for each particular program, the author recommends the responsive evaluation approach. It is an approach that sacrifices some precision in measurement, hopefully to increase the usefulness of the findings to persons in and around the program. Many evaluation plans are more "preordinate," emphasizing (1) statement of goals; (2) use of objective tests; (3) standards held by program personnel; and (4) research-type reports. Responsive evaluation is less reliant on formal communication, more reliant on natural communication. (Contains 2 figures.)
