Sieves to nebula network

Some accute problem seems to be being able to usher apart Constructivism from Connectivism.

How about to say that Constructivism is the child of the early XIXc Structuralism, Piajet speaking of scheme or schemata, while describing understanding, which are some kind of 2D scalable sieves, and say that Connectivism is akin to later XIXc Systemic Sciences, where the common figure is a 3D dynamic nebular meshing of a neural network or of internet ?

And I'm seduced by the distinction made Diane LARSEN-FREEMAN (2003) that knowledge (being a L2 learner Interlanguage or Internet itself) is less built than grown.
