A teacher generates teaching cases and uses recognizable details of a student. I propose that we build fictional situations that don't allow us to identify him.
In the example, changing only the name is not enough if they remain place and personal affair. A useful case illustrates a problem without exposing someone.
The teacher must verify the content before use and consider how it might be perceived. The personalization of the material must not be transformed into indirect publication of the life of the pupils.
