A Case Study strategy describes a complex situation, often in the form of a story, and asks the learner to explore its characteristics and decide on possible resolutions. Complexity is the primary difference between case studies and examples that can be easily presented and practiced through other types of strategies, such as multiple choice and matching. The case study strategy is useful in achieving learning at the application and analysis levels, and to present examples of content within appropriate business contexts; used in practice mode, case studies practice concepts and theories presented earlier in a course, after a learner gains knowledge and comprehension levels of learning.
