This document is a first introduction for educators, working in and outside of formal schooling, on how to identify, prevent and address conspiracy theories in education settings. It seeks to provide educators with key definitions and essential knowledge to grasp the complexity of the phenomenon and alert learners about the key characteristics and harmful effects of conspiracy theories for a first, immediate response. To support educators in this endeavour, this document outlines strategies to prevent the belief in conspiracy theories as well as to engage with learners who already believe in them.
