I became interested in the role of listening in language learning early in my career. As a novice teacher in a high school in West Africa, it gradually became clear to me that the most successful students in my classes were the best listeners. It wasn’t that they understood more or had a better command of English, but these successful students were obviously engaged, curious, and invested. They wanted to be involved. Over my first few months of teaching, I came to equate successful listening with these same affective qualities: engagement, curiosity, and personal investment.
