The type study method involves closely examining a single typical case to understand its characteristics and use it as a model for comparing and generalizing to similar cases. It has 6 main steps: 1) selecting a topic type to study, 2) motivating students, 3) stating the model case, 4) studying details, 5) comparing details to the model, and 6) generalizing conclusions. Its advantages are that it is simple, concrete, psychologically valid by focusing intensely on details, and time-saving. Disadvantages are that not all subjects are suitable, conclusions from a single case may not be reliable, and it risks forming hasty generalizations.
