A fundamental skill for primary school students is the ability to solve problems collaboratively. Most research has focused on the analysis and assessment of this skill in primary school students. However, little attention has been paid to the process of designing tasks to foster the development of collaborative problem-solving in these students. Furthermore, collaborative problem-solving can only emerge in a meaningful way if the tasks are designed in such a way as to encourage students to collaborate. This research focuses specifically on the process of designing tasks related to educational robotics, using the theoretical framework of Engeström’s activity theory. Participants, made up of primary school teachers and educational consultants, completed a questionnaire about their task design process and took part in two group interviews. The results highlight that the design of educational robotics tasks, aimed at developing collaborative problem-solving in students, is dependent on the technological and educational robotics task design skills of the designer. The rules governing the design of educational robotics tasks include the time needed to set them up and teamwork.
