Target group: Young people and young adults both domestically and abroad with no prior knowledge. Learning objective: Leads to the proficiency levels A1, A2, and B1 of the European Reference Framework in three volumes and prepares for the exams of the respective language levels. Deutsch.com is developed by a young, dynamic team of authors, with Prof. Dr. Gerhard Neuner providing advisory and collaborative support. Deutsch.com embodies the idea of the Common European Framework - the fundamental guiding principle of multilingualism! Learning German takes place "in the minds" of the learners within a context of multilingualism. This means that both the previously learned foreign language(s) and the mother tongue can be used to learn another foreign language. Against this backdrop, both language instruction and language acquisition should be viewed. The goal is to learn efficiently and save time.
