Constructivist theories of learning grew from cognitive theories which have roots in objectivism, but they reject the objectivist tradition. In order to answer questions that may arise around those issues, it is necessary to clarify the differences between objectivism and constructivism. Also, it is necessary to understand the differences among various schools of CTL before drawing on any of them to guide instruction. Objectivism as the Target of the Constructivist Revolution Constructivist educators think that objectivism has become inadequate to meet educational needs of today.
Behaviorists believe the function of the mind is to mirror an external reality.
Cognitive science is a revolution to behaviorism in that it acknowledges the mind and its function in learning. However, most cognitive psychologists only recognize the mind as a reference tool to the real world. Learning is more concerned with what learners know and how they acquire it. Based upon these ideas, educational goals and objectives as well as instructional strategies and learning outcomes are prescribed by teachers or designers. A teacher's responsibility is to map a reality or structure onto the mind of a student by controlling the learning process to progress toward previously determined outcomes.
