Not only the world is changing but also a way of education. The main purpose of the article is to focus on critical thinking in preparing pre-service Informatics teachers. It is described how essential is critical thinking, not only from the global reason but also our national - Slovak - point of view. We have used the case study method to support critical thinking in the preparation of pre-service Informatics teachers. We have created a collection of didactic situations which we handled into case studies using the AAA method (annotation, analysis, alternation), supplemented by tasks focused on critical thinking about the case study and further creative topic elaboration. As an example, we present a case study on Hoax Messages.
