In the current issue of Modern English Teacher, http.//www.onlinemet.com, there's a very informative, useful and convincing article by Sheila Thorn on 'Debunking Authentic Listening (MET Vol 21, No 2, pgs 65-69) in which she puts the case for using authentic listenings in the classroom.
She begins by explaining 5 popular misconceptions in ELT listening before considering authentic listening texts and activities (or the lack of) in ELT coursebooks. She then considers the four stages to the listening process and goes on to provide practical examples of how theory can be put into practice.
She concludes by proposing that by exploiting authentic listenings in the classroom, teachers can help students become more effective listeners.
