Anyone who wants to learn a foreign language of their own accord is highly motivated. Every language teacher likely dreams of fully harnessing the potential of this motivation on the journey to learning a foreign language.

Milica Sabo demonstrates, using empirical data, the demand for such teaching and learning principles at German universities and how they are evaluated. Additionally, she clarifies whether these teaching and learning principles are also suitable for use in the instruction of a smaller language, such as Croatian in this case.
