The Case Study Situation

DOE-STD-1058-93

For other types of case studies, the focus can be noted in the instructor's lesson plan

stating the purpose of the case study activity.

4.2 The Case Study Situation

Establish a situation that illustrates the focus of the case study. This requires the

instructional developer to draw upon actual events or their own experience to develop typical

problems. The situation should provide an appreciation that the event occurred and has the

potential to occur at the facility. The situation can be introduced in an overview of the case
