Difference between constructivism and constructivist

Confrey describes constructivism as a belief that all knowledge is necessarily a product of our own cognitive acts.
The active role the learner takes in constructivist learning sharply contrasts with one in which learning is the passive transmission of information from one individual to another.

Constructivism sees the teacher step aside to a new role as facilitator, pairing students with peers, learning processes, and another at key moments based on data and observation while the students create their own knowledge and even early learning pathways.

Constructivism has also informed the design of interactive machine learning systems, whereas Radical Constructivism has been explored as a paradigm to design experiments in rehabilitation robotics, more precisely in prosthetics. ^ White, Fiona Ann; Hayes, Brett Kenneth; Livesey, David James (2016).
