I went from this at Samizdata to this at tBBC, to a comment on this, to this blog, and to this posting there.

Quote:

What is an educational blog?

- An additional communication channel between teacher and learner
- A searchable archive of notes and handouts including downloadable worksheets and documents
- Signpost learners to additional resources
- Support questioning and discussion
- Provide a channel for comment, criticism and evaluation
- Open the teaching and learning process publicly to other interested parties

… which sounds, in a way, pretty old school to me. Which just might be the point.
