Teachers shape and control nearly 70 percent of the classroom with their language. Therefore, engaging with one's own teaching language and conscious conversation management is essential for the professional development of all educators. This practical handbook presents a multimodal concept of teaching language that includes paraverbal, nonverbal, and verbal means, in a clear and practical manner. The concrete implementation is illustrated and discussed not only in classroom discussions but also in language-sensitive subject teaching and speech therapy instruction. Additionally, the book focuses on promoting multimodal communication behavior among students with special educational needs in the linguistic, cognitive, and social-emotional domains in the classroom.
