Clear structure. For each lesson unit, there is at least one basic page and one material page. Basic pages convey subject matter in an easily understandable and clear manner. With meaningful illustrations, concise texts, key phrases, a vocabulary box, and differentiated tasks, students grasp and internalize the material. Material pages provide student experiments and task-based activities. This allows competencies to be acquired and applied in a student-centered and action-oriented way. The variety of these materials takes into account different learning levels and individual preferences. Additionally, there are specially integrated supplementary pages. Method pages guide step by step. The Expand and Deepen pages are ideal for differentiation. Summary pages provide the essential content for review. Self-Test pages offer tasks for independent competency assessment. The differentiation concept is based on an extensive material pool for heterogeneous learning groups. The tasks are presented at three levels, with basic and material pages in a 1:1 ratio. With this versatile offering, you can directly prepare and design your lessons using the textbook.
