The first I have heard of the concept of "navigationism" instead of connectivism. The article seems to negate the existence of the theory of connectivism, while elevating the concept of constructivism.
Interesting read. Similar themes to A Challenge to Connectivism (http://learningevolves.wikispaces.com/kerr), but in a more academic and non-contrary tone. Argues that connectivism is a subset of navigationism, but doesn't force a separation of navigationism and costructivism. The charts on 13-14 were useful.
