Diana Laurillard in Singapore

This looks interesting http://ial-als.blogspot.co.uk/2012/04/keynote-speaker-professor-diana_13.html There is a symposium coming up in Singapore about Adult Learning. Seems a good context for teaching as a design science. But I'm still not clear what is meant. This could be significant if applied to all forms of teaching. Trouble with reading blogs is that you often find you need to buy a book.
