Although the term learning has many possible meanings, the term as used by teachers emphasizes its relationship to curriculum, to teaching, and to the issues of sequencing, readiness, and transfer. Viewed in this light, the two major psychological perspectives of learning behaviorist and constructivist have important ideas to offer educators. Within the behaviorist perspective are two major theories or models of learning, called respondent conditioning and operant conditioning. Respondent conditioning describes how previously neutral associations can acquire the power to elicit significant responses in students. Operant conditioning describes how the consequences and cues for a behavior can cause the behavior to become more frequent. In either case, from a teacher's point of view, the learned behaviors or responses can be either desirable or unwanted.
The other major psychological perspective constructivism describes how individuals build “construct” knowledge by engaging actively with their experiences. The psychological version of constructivism emphasizes the learners' individual responses to experience --their tendency both to assimilate it and to accommodate to it. The social version of constructivism emphasizes how other, more expert individuals can create opportunities for the learner to construct new knowledge. Social constructivism suggests that a teacher's role must include deliberate instructional planning, such as facilitated by Bloom's taxonomy of learning objectives, but also that teachers need to encourage metacognition, which is students' ability to monitor their own learning.
