Here's a dry-run for a talk I gave about three years ago.

These are the slides although I think they were not exactly the same when I gave the talk

The slides go into a lot of detail about the time required by the teacher.

My students were using ipadio at the time, but I hope the same sort of thing can be done with Anchor, Spreaker or SoundCloud.

Of late I've been looking at the idea of getting students to use Padlet and a timeline format to create a repository e-portfolio of all their recordings and a second padlet with the timeline format, too, to display and share their best recordings each week

Which of these apps would be best? They are all available for Android phones and iPhones. They all have RSS feeds. So they should be easy for me to follow using #feedly. Will it be easy to send students feedback on their speaking? How easy will it be for students to add recordings to their #E-portfolios on #wordpress or #blogger?
