Focusing on the teaching of computer science in the generative A.I. (GenAI) era, the 4^th edition of this Guide to Teaching Computer Science aims to contribute to the urgent effort to rethink and redesign computer science education.

This Guide to Teaching Computer Science is intended for all computer science educators, from elementary, middle and high school to academia. It is organized in a way that enables an immediate application of its main ideas. This goal is achieved by presenting the rationale for addressing a variety of computer science education topics, as well as their detailed actual teaching process (including activities, worksheets, topics for discussions, and more). The rise of GenAI necessitates immediate changes in computer science education, even as we recognize that predictions about the future of the discipline of computer science—and of educational systems more broadly—must be made with caution.

· · · · Topics addressed in this guide include the following in the context of computer science education: research in computer science education; learners’ alternative conceptions; types of questions; assessment; teaching methods and learning spaces; lab-based teaching; teaching planning; teacher preparation programs; and prospective teachers practicum.

The 4^th edition of this highly useful guide includes 232 activities. This unique resource can be used by many people involved in computer science education: in particular, instructors of an MTCS course, instructors of in-service teachers’ professional development programs, and teachers across all levels and students.
