The standard work "Concrete Subject Didactics in Chemistry" is now available in a fundamentally revised edition that meets the requirements of a successful, competency-oriented chemistry education. For the first time, renowned authors from the first and second phases of teacher training have collaboratively developed a chemistry didactics textbook. This provides a universal teaching resource for all phases of teacher education, addressing the specific needs and perspectives of chemistry instruction. It offers insights for studies, internships, and practical teaching, presenting a comprehensive view of the entire chemistry curriculum; a wealth of stimulating ideas for didactically sound methodological measures and decisions; as well as arguments and suggestions that effective, impactful chemistry teaching can be planned in its fundamental structures while remaining open to a sensitive and engaged approach.
