Contrastive Grammar Courses

German, Danish and English — each written for a speaker of one of the others

Three self-contained grammar courses built on the same method: explicit rules anchored in examples, quizzes as retrieval practice, and a systematic comparison with the learner’s native language so that positive transfer is used and negative transfer is flagged before it becomes a habit.
