We often don't recognize listening as the kind of skill we need to spend time and energy practicing. We may think there's nothing to it.
Students come to school speaking and listening.
They learn pronunciation of words by listening, and most of a child's beginning vocabulary comes this way. All of this is set when students come to school. If it is to be learned, it must be taught. Studies have shown it can be taught. Children who have rich listening experiences not only develop greater language skill than children who do not, but even develop more of their innate potential for intelligence.
