The book "Writing in Teaching Materials" by Henriette Hoppe offers a comprehensive scientific analysis of selected German teaching materials. It examines the use of these textbooks by teachers and learners and identifies various patterns in the handling of the materials. Through expert interviews, it provides a deep understanding of the didactic approaches and their implementation in the classroom. Special attention is given to the modeling of the text type report, which is addressed in the teaching materials of the 1990s. The analysis is conducted using a structured analytical framework that makes the development of the writing didactics discussion traceable. This book is a valuable resource for educators and researchers engaged in writing didactics in German language instruction.
