Brief description of the concept: The working tool represents a novel concept between training scripts and traditional textbooks. It is designed as a workbook for entering, highlighting, checking, and underlining key statements and key expressions in texts, with a strong focus on action-oriented and student-centered learning. It aims to enable exemplary and self-organized learning for students, fostering learning success experiences and thereby enhancing learning motivation. The tasks are generally organized in such a way that students receive concrete assistance in solving them through information boxes, method boxes, and checklists, through the opportunity to fill in gap texts, through multiple-choice tasks, through the option to choose between answer choices and justify their selections, as well as through example solutions. The active and hands-on engagement with the materials is emphasized.
