Scientific basis

mathildr was developed together with people with trisomy 21, Down syndrome. The system was developed in the framework of a representative study carried out by the University of Hamburg. The study showed that learners with trisomy 21 rely on abstract learning materials and that they benefit from items being grouped into pairs.
