The Your Turn guidebook is a step-by-step instruction for teachers (in training) to create and implement their own design projects for upper primary and lower secondary education. It provides an overview of the variety of tools for Co-design projects with children, a step-by-step guidance, advice on the approach and striking examples. Performing these kind of projects, students gain experience with designing around appealing themes from their daily life.The guidebook is based on the results of the research project Co-design with Kids, funded by Dutch research organizations NRO and NWO. In this project researchers from Delft University of Technology and a large consortium of scientific and public partners have collaborated with teachers and pupils. This guide provides support for building co-design processes that benefit both designers and the participants@en
