Deutsch im Blick (Abrams)
Zsuzsanna Abrams and co-workers · University of California Santa Cruz
Deutsch im Blick is an online, non-traditional language learning program for beginning and early intermediate students of German. It is quite different from your traditional language textbooks, so it might take some getting used to. However, you’ll enjoy learning German as long as you like to play with language, explore how vocabulary and grammar work together to create meaning, and are curious about the cultures of the German-speaking countries.
