Active Listening: Expanding Understanding through Content, is the highest level of the Active Listening series, a three-level listening course in North American English that draws on recent research in comprehension. This intermediate to high-intermediate text offers 20 engaging, task-based units, each built around a topic, function, or grammatical theme. Active Listening activates students' knowledge of a topic before they listen, giving them a frame of reference to make predictions about what they will hear. At this level, students learn to listen through a careful balance of activities that make use of real information from a variety of sources to promote understanding.
