Here’s how I see these concepts in my mind, hope it is interesting for you. I picture constructivism more as the individual learner being provided a foundation by the teacher, then building a house on top of it. If the learner is really motivated, s/he will decorate the inside and buy nice furniture too.
I picture Connectivism in a much less “boxy” way. The teacher provides some initial knowledge but encourages the learner to use that as more of a virtual knowledge “lilypad” to spring from. The learner is free to seek out connections and synthesise his or her own concepts, then come back to the community to share new learnings and insights. Their conceptual and social networks grow naturally as the quality of connections increase.
