1/ Ever since I did BBC Schools Radio programmes with accompanying booklets (from 1972) I've been trying to find ways to link the spoken to the written: books with cassettes/CDs/QR codes; performances with books to buy; performances in libraries; YouTube channel of poems/stories
2/ When we show children that the stuff that can be spoken can also be written, we show them how the written code works as a way of conveying the stuff that they enjoy, are moved by, intrigued by, wonder about.
3/ I've always hoped that children can shunt between oral recordings or my performances and written forms of what I'm speaking - through books, booklets etc. Sometimes the video/audio is standalone, sometimes the written, sometimes both at the same time.
4/It's a different or complementary theory of literacy in that its starting point is not purely the written. Alongside it, I've always advocated 'scribing' children's stories/poems etc + shared reading back of the written.
