This document discusses listening skills and strategies for teaching listening. It addresses the differences between listening, reading, speaking and writing. Listening is defined as a receptive skill that involves hearing and neurological processing of auditory stimuli. Effective listening requires both bottom-up processing of individual sounds and top-down use of context and prior knowledge. The document provides examples of classroom activities to develop L2 listening abilities, such as having students listen to recordings and complete tasks, or use transcripts to understand discourse markers.
