The document discusses different approaches to syllabus design in language teaching, including grammar-based, lexical, functional, situational, topic-based, task-based, and multi-functional syllabuses. It provides examples and criteria for each approach, such as including common language, prioritizing learnability over rare structures, and organizing lessons around real-life topics or tasks that engage students. The best approach incorporates multiple elements through a balanced "map of the book" to accommodate different aspects of language learning.
