In 2021, Sign Language of the Netherlands (NGT) was recognized by law as one of the country’s official languages. To raise societal participation of deaf citizens, the law prescribes that the use of NGT in Dutch society must be increased. The present project aims to contribute to this end. It involves a collaboration between UvA and Prowise, a company that provides a digital language learning tool called Taalzee (“Language Sea”), which is used by more than 2.000 primary schools in the Netherlands.
