The "Bach / Timm" with its concept of action-oriented teaching has proven to be a standard work for teacher training and professional development for years. The newly released 5th edition addresses the pedagogical, subject-specific, and structural challenges that have shaped foreign language teaching in recent years: early English instruction in primary schools, bilingual subject teaching, an expanded range of new media, discussions about educational standards and competency levels, educational theoretical concepts such as constructivism, process and learning orientation, learner autonomy, and subjective theories. The established foundational chapters have been updated to reflect the latest developments in subject didactics, and focal points such as "New Media" and "Educational Standards in English Teaching" are introduced in new chapters.
