Speaking of constructivism, which is another theory of learning I'm learning about, here's a very short article on Cognition as (Inter)Action in the Social & Material World
I still haven't got a firm grasp of what behaviourism, cognitivism, constructivism, connectivism, are or the differences between them.
I'm finding the work of George Siemens to be interesting and helpful in that regard, especially his essays on Connectivism, and Learning Development Cycle.
While Steinkuehler focuses on cognitive theory, Siemens brings into play the factors of "the half-life of knowledge" (the time span from when knowledge is gained to when it becomes obsolete), and the abundance of knowledge and the rapid increase in information.
This leads to David Sifry's suggestions in his report State of the Blogosphere, February 2006 Part 2: Explore: Dealing with Information Overload.
In future posts I want to explore Vygotsky's work a little.
