An essential activity of reading for student success in all disciplines is learning through reading (APL). To support their students in this sense, teachers from an urban school in a disadvantaged area developed collaboratively an approach of APL they adapt according to their group and the discipline taught. This study aims to explore the relationship between the activity of APL designed by the teachers of the 3rd cycle including a series of tasks and texts proposed and student responses to the various tasks. The main results show that few of the proposed tasks actually require reading and that the main source of information remains textual. Consequently, the use of the image as information support is still marginal and planning activity of APL, as the choice of texts, remains a major challenge in planning for an APL context.
