The document discusses different approaches to teaching listening skills, including bottom-up and top-down processing. Bottom-up processing involves breaking down utterances into individual chunks to understand meaning, while top-down processing uses background knowledge and context clues to infer meaning. The document also outlines strategies for developing listening as a comprehension skill versus an acquisition skill to learn new vocabulary and structures. Classroom activities are suggested to help students notice differences between texts and their memory, and to restructure language from the texts into their own spoken or written output.
