Evaluation and Change in Education / Egon G. Guba.

Evaluation, defined as the process of providing and using information for making educational decisions, is a major factor in the achievement of planned change resulting in improved education. This kind of change is differentiated as neomobilistic or moving toward a planned new state, in contrast to evolutionary change and homeostatic change. Four distinct evaluations--of context, input, process, and product--are necessary in the neomobilistic change process. To perform the full range of evaluation tasks competently, a minimum of six specializations or evaluator roles is required--interpreter, instrument specialist, data processor, information specialist, reporter, and data collector. Six steps outline the procedure for designing an evaluation at each stage of the process. Ten criteria describe the requirements that must be met by evaluative information. (JK)
