Didactical Materials Customizable to Suit Classroom Needs: A Valuable Resource for Teachers

Abstract

Can free, adaptable, and didactically validated materials have an impact on teachers’ practices and competences? This issue has been focused on by the researchers working on the MaMa—Matematica per la scuola elementare (MaMa—Mathematics for the primary school) project, commissioned by the Dipartimento dell’educazione, della cultura e dello sport (Department of education, culture and sport) of the Canton of Ticino (Switzerland). Since 2019, this project has been aiming to create materials for teaching and learning mathematics in primary school, in line with the curriculum. The innovative MaMa materials, which can be freely downloaded via the mama.edu.ti.ch platform, are addressed to both teachers and learners. In many cases, they are editable, so that they can be customized by each user to suit the different teaching contexts and pupils’ learning needs and be grouped into collections. Via the administration and analysis of a questionnaire, this article investigates how teachers use the materials, and whether they influence teachers’ practices and competences. The results of this pilot study show that MaMa materials are perceived from teacher–users as “materials for teacher education and development”, especially at the disciplinary level, supporting both the instructional design process and the appropriation/transformation of didactical resources to deal with the challenges of differentiation in the classrooms.
