The purpose of this research is to find evidence for the assumption that allowing children to create their own news messages is an effective approach to teach them how to distinguish between reliable news and fake news. Three students of the primary teacher training programme of The Hague University of Applied Sciences developed five lessons concerning fake news and five Kahoot! quizzes for each of those lessons. They taught the lessons they developed under the supervision of a primary school teacher and one of their lecturers from the university. A Friedman test on the scores of the Kahoot! quizzes indicate that the children made progress over the course of the study. In addition, it appears that the children appreciated the lessons and that they have learned how news is created and how fake news can be recognised. The outcomes of this study have prompted a larger, international Erasmus+ project. Schools and libraries in three countries will investigate similar innovative blended-learning approaches for pupils between ages 12 to 15.
