Training disciplinary teachers: the specialised language of Mathematics

Extensive research has consistently highlighted the critical importance of linguistic proficiency in facilitating the comprehension and mastery of subject content, thereby ensuring effective learning across the entire curriculum. Consequently, it is essential to foster an understanding among educators - at all levels and across disciplines - of the principles underpinning language instruction. This paper presents the findings of a professional development program tailored for secondary school teachers, emphasizing the specialized linguistic demands of mathematics and the integration of innovative, data-driven learning approaches within digital learning environments to support its teaching and acquisition.
