Connectivism, a new learning theory?

I was thinking the terms in learning theories. The researchers named them by different emphases, such as reflective, experiential, informal, virtual, active, inquiry-based and so on. Some of them have certain similar ideas and key points. Also, I com across this article “Connectivism: a learning theory for the digital age” written by George Siemens. I agree with him that learning theories have been developing from three dimensions: behavioursim, cognitivism and constructivism. However, for me, the view of ‘connectivism’ is more similar to the dimension of so-called ‘social/realist constructivism’ or ‘collaborative constructivism’. It is another term that stresses the ‘connective’ element in learning.
