The document discusses the history and development of language curriculum. It describes how curriculum development involves determining learner needs, objectives, syllabus, teaching methods, and evaluation. Several historical methods are outlined, including the structural method from the 1930s-1960s. This method focused on vocabulary and grammar selection based on teachability, frequency, and learnability. Gradation approaches ordered content based on linguistic distance and communicative need. The assumptions behind syllabus design were that language consisted of vocabulary and grammar, learners had identical needs, and learning was determined by textbooks.
