The student book is particularly characterized by its differentiation: heterogeneous learning groups can independently work through the content using various tasks and support. It offers high visual clarity through numerous aids such as checklists and repetitive exercises for self-assessment, sample texts, visualizations, and summaries. The chapter structure is transparent from the first to the last page. Each chapter includes targeted language and method training, as well as a supplementary section in the appendix covering spelling, grammar, punctuation, operators, and project work. The German book for vocational schools follows the proven modular principle of the German book series.
