Moedint2 is a (web)app that contains mother tongue specific problems with learning a certain language. In Turkish, for example, there is no distinction between ‘he’ and ‘she’, which can be problematic when learning Dutch. The app details such common problems with learning a specific target language (e.g. Dutch) from different mother tongues, and includes suggestions for exercises that teachers might use. Clever implementation allows the app to be used for a variety of different target languages: a French version is in the making.
