We all have a shared interest and common goal: to explore and promote insight into both theoretical and practical aspects of English teaching and learning. The book opens with a historical overview of English teaching in Norway. Each chapter is devoted to a specific area of the subject and discusses the topic in a historical context, before exploring various theoretical concepts and relevant research. The topics are also discussed in relation to previous and current Norwegian curricula. Special focus is given to discussing practical classroom work as well as theoretical and practical challenges related to the topic of each chapter. This second edition of "Teaching English in the 21st Century" has been revised and updated to take into account the changes in "The Knowledge Promotion" of 2020 and recent research. The book brings together historical, theoretical and practical aspects of the subject. As such, the book is an invaluable tool for teachers, student teachers, researchers and others engaged in the continuously developing field of English didactics. All chapters in this book have been peer reviewed.
