Top-down listening activities
Do you ever get your students to predict the content of a listening activity beforehand, maybe using information about the topic or situation, pictures, or key words? If so, you are already helping them to develop their top-down processing skills, by encouraging them to use their knowledge of the topic to help them understand the content. This is an essential skill given that, in a real-life listening situation, even advanced learners are likely to come across some unknown vocabulary. By using their knowledge of context and co-text, they should either be able to guess the meaning of the unknown word, or understand the general idea without getting distracted by it.
Other examples of common top-down listening activities include putting a series of pictures or sequence of events in order, listening to conversations and identifying where they take place, reading information about a topic then listening to find whether or not the same points are mentioned, or inferring the relationships between the people involved.
