It can be hard to know where to start helping students to improve their listening skills and also to pinpoint the issues that are causing them problems. Here's some recent articles that I've found useful and have helped me clarify my ideas:
- on the difference between top down and bottom up listening situations by Catherine Morley http://tinyurl.com/d8fqnwh and Sue Swift http://eltnotebook.blogspot.com.es/2007/02/teaching-listening-top-down-or-bottom.html
- Developing Bottom-Up Decoding Skills for Listening by Sue Swift
- Elementary Podcasts which you can download or access as an app for mobile devices
- Word on the Street series which focuses on everyday language
- Big City, Small World an audio soap which is also available as a mobile app
- ELLLO short videos and questions
And if you're looking for more "authentic" resources there's:
- Voice Of America | Learning English
- VideoJug useful because many of the videos come with a transcript
- the great short films and lesson plans on Film English – Kieran Donaghy
