Social creativity in the collaborative design of a digital resource embedding mathematics into a story

International audience ; Our research was carried out in the framework of the MC2 European project (http://www.mc2-project.eu/, 2013-2016) aiming at developing a socio-technical environment for the design of digital resources fostering creative mathematical thinking. Through a network of theories, we conceptualise and study social creativity that occurs during collaborative design of a digital resource embedding mathematics into a story. We focus on factors that trigger, or hinder social creativity and that influenced a group of designers, made up of mathematics teachers, teacher educators and researchers with diverse expertise, broadening perspectives, supported by a socio-technical environment during the design process.
