There are some great ideas here – I especially like the entry on Externalising Ourselves. I am going to use a quote from this in my ETA Conference presentation on Saturday about Online Learning and Pedagogy:
The ability to connect concepts and ideas and to understand and be understood by others requires that we render our thoughts in some type of format that permits communication. The development of symbols, language, and writing permits externalization of thought and thereby the capacity to create and network concepts and ideas.
The same wiki page also has a link to a very interesting document about Connectivism as a Learning Theory. I had to laugh at the title, as it sums up so many arguments discussions I have had with people about using online tools, for teaching or otherwise: ‘Connectivism: Learning Theory, or Pastime of the Self-Amused’!
