A class compares an output with available sources. I propose that we choose a circumscribed topic and have every correction motivated.
In the example, students distinguish a wrong fact from an incomplete explanation. The activity must not teach that the system is always wrong, but that an answer must be evaluated with criteria.
Delicate content that requires skills that are not present should be avoided. The discussion should also include a correct output, so as to train judgment instead of automatic suspicion.
