Based on the basic elements and principles of "communication," this book unifies syllabus, methods, and materials to provide teachers with guidance and examples to help them build standards-based language classrooms where communication is a priority. The book is divided into eight parts, which discusses practical topics such as curriculum design, language proficiency development strategies, language and culture connections, using assessments to help learners grow and promote curriculum development, managing the learning environment, using learning tools effectively, teacher professional development, and curriculum planning and implementation.
