The document summarizes the origins and historical development of language curriculum development. It discusses early approaches that focused on syllabus design and selection of vocabulary and grammar to structure language courses. Selection criteria included frequency, range, teachability, and learners' needs. Gradation principles like simplicity, centrality, learning ability and sequencing were applied. Early methods emphasized vocabulary and grammar as the building blocks of language. Contexts assumed learning a foreign language through textbooks, with universal needs. This established foundations for modern curriculum development focusing on determining appropriate content, experiences, and evaluation to achieve learning outcomes.
