Also Known As: Feel the Pain, Experience of Problems
The students got exercises which require the application of design patterns. Their experience is mainly based on some school projects, and therefore limited. You want to ensure that the students look at the Context, Problem and Consequences First, but they do not focus enough on context and problem or they do not see the problem as a real problem.
Students often apply patterns without understanding why the problem really is a problem. They are not aware of the consequences if this problem is not addressed properly.
Therefore: Let the students experience the problems addressed by a pattern first hand before they implement the pattern. Make sure that they understand what consequences it has to not address these problems.
This pattern is specific for teaching design patterns to students without prior (excessive) design experience. It also can be inappropriate to let pattern users experience the problems addressed by the patterns, e.g. when teaching pedagogical patterns one should not enforce the problems addressed by pedagogical patterns. We therefore do not consider this as sufficiently high-level to be marked with one asterisk.
