New technologies are a challenge that our schools must take up. As part of our eZoomBook (eZB) project, we have developed eZB – enriched eBooks based on heritage texts. The eZB format makes it possible to integrate several tabs and documents (versions in different languages, abstracts, images, audio documents, video, etc.) that are quickly accessible through a "zoom" feature. In line with the mission that Hannah Arendt assigns to the school, our goal here is a transmission of a literary heritage by introducing learners to a world necessarily older than they are. Through the eZB digital tool, we concretely give them "the means to understand and organize complexity" (Becchetti-Bizot, 2012) and to integrate OSS (Secondary Semiotic Objects) within the context of a collaborative class project. Our work, in coordination with the Academy of Nantes, shows the interest of eZBs for teachers of cycle 3 and presents the results of our experimentation in a primary class. Through a multimodal approach, the eZB makes it possible to bring together, organize, and promote the activities carried out during the semester, all the while preserving the freedom of teachers who wish to improvise by calling upon their pedagogical experience and intuition (Gladwell, 2005).
