This is a pronunciation blog, so...
What could they do with access to every extant website?
My suggestions would be these:
- ask students for their favourite websites for learning English (and make a list)
- ask students for YouTube examples of different accents and dialects from their own languages
- work through a list of good pronunciation resources for learners
- use YouTube for listenings for pronunciation noticing instead of content
- 'timecapsule' their students's English pronunciation by making videos of them now
Regarding Number Three... what are your top favourites?
If I had a group of English language learners who wanted to learn more about pronunciation, I'd show them these to get the whole IPA chart thing out of the way and show them how they could work a bit more autonomously.
- The University of Iowa's Phonetics Interactivity
- An interactive phonemic chart: Underhill's or a more complete one
- English Central's samples with voice analysis
- Alex Bellum's videos on the British Council site
- This color vowel chart interactivity...
There's loads more of course, but these are my typical recommendations.
The Internet... not so bad after all.
