The document discusses the lexical approach to language teaching and learning. It emphasizes that vocabulary plays a central role in communication over grammatical rules. The lexical approach focuses on having students learn language as lexical chunks or phrases rather than individual words. It involves intensive listening, reading, noticing patterns and collocations. Effective strategies for teaching vocabulary through this approach include attracting students' attention to collocations, individual instruction on collocations, and activities using visuals, puzzles and miming.
