Skill-based syllabi group language skills like listening, reading, writing and speaking together based on competencies rather than language settings. The primary purpose is to teach specific skills useful for language use. Examples include reading for main ideas, using context clues, or writing well-formed paragraphs. While useful when learners need certain skills, skill-based instruction may limit general language development and some question if skills are dependent on overall proficiency. It is best for teaching defined skills to adults rather than broad language programs for children.
