An experience of Universal Design for Learning in geometry at the lower secondary school

Abstract

The article describes an educational path implemented in a ninth grade class in the Canton of Ticino, designed to meet the growing needs for inclusiveness of today’s school system. To achieve this goal, the Universal Design for Learning (UDL) model was chosen. Specifically, the focus was on the first principle of the model, which aims to provide multiple forms of representation for materials and lesson content. The path covered the following three geometric topics: cone, similarity in space, and sphere. This paper presents the part of the path related to the cone, along with references to consult the entire work.
