From my research and studies, my thinking leans towards the ideology of Jean Piaget, who expressed mechanisms by which knowledge is processed by learners. He suggested that individuals construct new knowledge from their experiences.
When individuals adapt or assimilate, they incorporate the new experience into an existing structure without changing that framework. This often occurs when individuals' proficiencies are aligned with their internal representations of the world, but may also occur as an inability to change a defective understanding. Conversely, when individuals' experiences dispute their internal depictions, they may change their insights of the experiences to fit their inner representations.
Accommodation is deemed the practice of restructuring one's mental representation of the outside world to fit different experiences. In some instances, accommodation is understood as the mechanism by which failure leads to learning: when we act on the anticipation that the world works in one way and it disturbs our anticipations, we often come up a little short, but by accepting this new experience and reframing our model of the way the world operates, we gain new knowledge from the experience of challenge, or others' failure.
Keep in mind, that constructivism is not a specific pedagogy. In a nutshell, constructivism is a theory recounting how learning occurs, regardless of whether learners are utilizing their experiences for complex or simple tasks. Either way, constructivism suggests that learners construct knowledge out of their experiences.
