For those who are interested in project-based distance learning I
recommend Eunice Askov’s chapter on Australian Distance learning in the
NCSALL Publication on adult education DL, _Expanding Access to
Adult Literacy with Online Distance Education_
http://ncsall.gse.harvard.edu/research/op_askov.pdf
For example, at the TAFE (Technical and Further Education) Institute in New South Wales, students use WebCT to do Webquests, just one of many
interesting examples Askov describes. Also, the appendix of this
publication has an excellent set of descriptions of major DL products.
