Constructivism is a learning theory based on the notion that learners generate meaning through iterative mental formulation and reformulation of theories that satisfy the search for understanding.

An understanding of how cognition is realized or instantiated in a physical system, especially a body, may require or be required by an account of a system’s embedding in its environment, its dynamical properties, its (especially phylogenetic) history and (especially biological) function, and its nonrepresentational or noncomputational properties.
