Here is another seminar that was live streamed and this time put on YouTube: A focus on materials development with Rachael Roberts and Adam Kilgarriff:
The first presentation starts at around 5 minutes. Rachael Roberts, the first speaker, gives a very interesting talk about writing materials.
The second speaker (after around an hour) is not such a good presenter, but still has some interesting points about using corpora in the classroom without scaring the students!
