This pattern is appropriate for all kinds of material that is first presented theoretically in a lecture and which shall then be applied practically in exercises. The students must be prepared to participate actively in the learning process. If there is too much material that must be presented or taught, time is scarce and cannot be wasted or invested in pedagogical games. The time for the preparation for the lecture should not be overwhelming, not for the teacher and also not for the students. The best possible knowledge transfer can be reached by communicating the knowledge audio-visually where the students are involved actively and both, the teacher and the students, have fun.
Repetition helps to make knowledge unforgettable.
When the style of lectures resembles a one-way communication, the listeners easily get bored or distracted. When the theory of the lecture shall be applied in an accompanying exercises course, the students fail. If the theory is re-explained, the students fail to see the problems and again miss some subtle or critical points. Let the students apply the theory by answering a self test after they have heard the theory once before telling them the theory another time. This has the benefit that the students will know where they failed and what they did not understand.
