Rachael Roberts’s (@teflerinha) post on ‘discovery listening’.
The PowerPoint from my presentation at last year’s English Australia PD Fest: Discovery listening. The end of the presentation includes some comments from C1-level students who did this activity with me last year.

Brilliant- thanks for posting this. I particularly liked the marked up transcripts at the end of the presentation, showing the difficulties students had at different levels. Really interesting.
