The document discusses the lexical approach to language teaching. It emphasizes focusing on vocabulary chunks like phrases, idioms and collocations rather than individual words. The lexical approach involves students observing how language is used, hypothesizing about patterns and experimenting with new language. This helps students learn vocabulary in meaningful contexts and sound more natural when speaking. The document suggests ways teachers can implement this approach, such as recording and recycling chunks, discussing degrees of meaning and having students express concepts in the target language.
