The book "Didactics of Computer Science" by Peter Hubwieser offers a comprehensive and contemporary approach to computer science education. In its third edition, it first addresses fundamental learning psychology aspects that are important for designing lessons. The author explains general didactic principles and provides practical tips for planning and conducting teaching units. A central point of the work is the argument for introducing computer science as a mandatory subject, especially in an increasingly differentiated information society. The teaching approach goes beyond merely imparting programming skills and focuses on fundamental principles of information processing. In the third part of the book, concrete lesson plans are presented as examples for implementing the learning content. This book is a valuable resource for educators who wish to design computer science education in an innovative and effective manner.
