The book "Didactics of Analysis" offers a comprehensive and well-founded exploration of the didactics of analysis in mathematics education at the upper secondary level. It takes into account current didactic discussions, theoretical concepts, and practical teaching experiences, aligning with the educational standards set by the Conference of Ministers of Education. The content is designed to assist students, trainees, and teachers in competently teaching the central concepts of analysis such as function, sequence, limit, derivative, and integral. The book highlights important aspects and foundational ideas of these concepts and presents typical approaches for teaching. Additionally, it addresses the role of digital mathematical tools in the learning process to illustrate their potential benefits for analysis instruction. Practice exercises encourage independent application and deepening of the content, emphasizing the practical relevance of the book.
