1) A structural syllabus focuses on teaching the grammatical rules and structures of a language. It breaks the language down into discrete grammatical points like verbs, nouns, and tenses. 2) A key feature is that students synthesize the analyzed grammatical structures into unconscious language use. The goals are for students to describe rules, judge grammatical correctness, and accurately use structures. 3) While structural syllabi allow for clear definition and measurement of grammar competence, critics argue it may mislead students and has limited applications due to problems with sequencing and transfer of knowledge to real communication.
