Constructivism is a form of epistemology(way of knowing something) which posits that knowledge of the world is a product of the interaction between the subjective observer and the objective world. This position would hold that although an objective world does exist; interactions with or descriptions of that world are strongly conditioned by the conceptual system through which it is perceived by the observer. Thus knowledge and “reality” are constructed through an interaction between the objective world and the observer. Constructivism exists in contrast to the ideas of objectivism, which hold the belief that a person can acquire knowledge about the world not mediated by subjectivity, that there is one “real world” and that this is largely transparent to our senses.
