I try to use German as much as possible in all of my classes so that by the time students are in the advanced levels we are using the target language almost all the time (3rd year - still need to explain some of the more difficult grammar in English) and exclusively (4th year).
One difficulty I notice students having is understanding instructions that are written in German. It's a challenge because I don't want students to miss a question on a quiz or test because they didn't understand the instructions but knew the material. On the other hand, I've noticed that if I write the instructions in both German and English, they don't bother to read the German instructions at all. Then, when I take away the English, they are lost.
What to do?
Recently when browsing on one of my go-to websites for German materials and ideas, ISL Collective, I came upon these great pictures of directions and their meanings.
The author, Martha from Austria, has very kindly shared them for free. (You have to join ISL collective to download materials, but it is free.) I plan to make posters from them for my room next year.
Here's the link to the Arbeitstechniken worksheets and flashcards.
