The MADITA project develops, evaluates, and disseminates a digital app to support students in Grade 1 in early math skills. It addresses the need to support students’ skills early on in schooling. The app will be research-informed and use AI to identify each child’s individual competence profile and their risk to develop math difficulties and to provide customized support for each child at their respective level. It will allow for teachers to monitor and evaluate students’ learning process with the app. MADITA facilitates digitalized, individualized, adaptive support of early math skills. The MADITA app will diagnose early math abilities using AI, generate customized support sequences, and provide meaningful, directly usable individual student profiles to teachers.
