An introductory book on incorporating shadowing into the classroom. It introduces shadowing as an effective training method that connects Japanese learners' "understanding" to "ability." Furthermore, it covers teaching methods, evaluation methods for practicing shadowing, and examples of its implementation outside of Japan. For those who hesitate to introduce shadowing, thinking, "I know about shadowing, but I don't know how to incorporate it into my lessons," or "It can only be used by advanced learners..." and for those who are already using it but are struggling with, "I want to know more effective ways to use it," or "How should I evaluate shadowing practice?" This is "a book on shadowing by teachers, for teachers and learners."
