Contructivist or not?

Here is a link to an game that came out of a constructivist learning (not teaching) setting in a kinder classroom. If you're familiar with the "centers" approach in the classroom - you'll recognize that this is a piece of that approach and one of four modules for self directed knowledge making when it comes to shapes.

IMHO - why bother doing games if its a reiteration of an objectivist tradition that has driven teaching (not learning) since Plato?

(anecdotally, the kids used the interface without direction, not the case for the teachers shown the module)
