DLL is a series of ten GFL units and three GSL units, which follow a competence and practice-oriented advanced training concept and can be completed independently of each other. All units include aspects such as how to deliver skills, grammar and vocabulary, phonetics, media didactics etc.
The core is formed by around 400 teaching videos, which provide authentic insights into classrooms all around the world.
All DLL units are available to buy in printed format. Alternatively you can work through them online on the Goethe-Institut learning platform.
