I liked the reference to vocabulary , vocabulary , vocabulary which we has seen in the studies about the word deficits that learners from poverty are coming to schools with. The whole thing need to feel like play celebrate imagination. Oral language is far more cognitively natural than written language and a place to concentrate for sure.
My quick ideas for doing this in preschool in a digital age would be to have things like
- skype/hangout to school
- film a play and play it back
- some words on tvs not for the kids but to stimulate teachers into trying to weave new talk into a day
