the basis for deciding whether the course met its planned objectives.
In addition, time data and other information from students are collected
to provide the basis for making revision decisions.
Evaluation is not unique to the ISD process, but no set of in-
structional design and development procedures can be called ISD
unless it includes an adequate internal evaluation.
Ideally, the internal evaluator would be assigned to a department
not directly responsible to the instructional design, development,
or delivery system manager. The more independent the evaluator can
be, the more accurate and useful his data will tend to be. An impartial
evaluator will be in the best position to verify that correct procedures
have been followed in obtaining the results of instruction.
It is the evaluator's purpose to remove as much of the guesswork
as possible from school operation. By careful analysis of the evaluation
data, a determination can be made as to the problems with the instruction,
and appropriate revisions can be made.
