The quality of the questions chosen is crucial for the success of Peer Instruction & Pingo sequences. The following list highlights particularly important aspects of the questions:
- They should be based on a specific input phase.
- They should be unambiguous, as otherwise the peer discussion will degenerate into an attempt to interpret the question itself.
- They should be neither too easy nor too difficult; either of these extremes can prevent a peer discussion from materializing at all, and can furthermore reduce the motivation of participants to provide feedback.
- They must be designed such that they allow for strong distractors, i.e. plausible but incorrect answers. To achieve this, lecturers must rely on their wealth of experience when constructing the questions. They should consider what mistakes students make over and over again, i.e. systematically.
