The word evaluation is used loosely to encompass many different activities and purposes. When educators evaluate a reading program, they may be referring to deciding which of several reading programs their school district should adopt; when evaluating a school-bell schedule, they may mean finding out how popular the schedule is among students and faculty and what the advantages and disadvantages of several other bell schedules may be; when evaluating students, they may mean administering achievement or psychological tests; and so on.
- The DEM was first put forth by Malcolm Provus; see Discrepancy Evaluation, McCutchan, 1971. It was further developed at the Evaluation Research Center in 1971–1975 by a team of people, including the author, led by Malcolm Provus. Different versions of the DEM have arisen. The views presented here are those of the author.
- This does not necessarily mean that the DEM evaluator will not be open to unexpected events. How to handle this problem is negotiated between client and evaluator; the important thing, again, is for the evaluator to stay away from setting and deciding on his/her own what information to collect.
