One of the sticking points about life and relationships both personal and professional, is to insist that ‘your’ viewpoint is the right viewpoint. To offer and incorrect statement or recommend an action that proves to be wrong is reluctantly followed by an apology.
Within school contexts, this can have atmosphere destroying and suspicion arousing outcomes.

For teachers, it can be all too easy to make mistakes. It may be the incorrect spelling of a word, the misunderstanding of roles played by children in some dispute, or getting it wrong when it comes to a particular fact being correct or incorrect. In these instances and others, to apologise to students for a mistake or misunderstanding is important. It models a correct social attitude to children and also earns respect from children and students.
