Clear structure - easy handling. Each unit begins with an introductory double page that presents the topic through images and places it on a timeline. The following introductory double page facilitates access to the subsequent content with an important event or an interesting problem. The thematic chapters feature distinct presentation and material sections. In-depth subchapters are clearly indicated. At the end of each unit, learners have the opportunity to test their subject knowledge and methodological skills through a self-assessment. A concise summary of the content concludes each unit. The appendix of the volume, which includes tip cards, methods for handling materials, teaching strategies, possible solutions to the self-assessments, a glossary of terms, and an index, supports independent learning.
