The dissertation When walls speak explores the links between pedagogy and architecture through examples from schools such as the École Camondo, drawing on the study by Gilles Grosson and Jean-Pierre Tixier entitled Innovating in Schools Through Design. It addresses five key points - clarity and hospitality, diversity of course formats and porosity, as well as scope - to offer innovative design solutions. Through questionnaires and interviews with students, the course director and a teacher, it aims to understand the impact of architecture and design on learning and pedagogy.
