Constructivism: changes in how students think

Behaviorist models of learning may be helpful in understanding and influencing what students do, but teachers usually also want to know what students are thinking , and how to enrich what students are thinking. For this goal of teaching, some of the best help comes from constructivism , which is a perspective on learning focused on how students actively create (or “construct”) knowledge out of experiences. Constructivist models of learning differ about how much a learner constructs knowledge independently, compared to how much he or she takes cues from people who may be more of an expert and who help the learner's efforts (Fosnot, 2005; Rockmore, 2005). For convenience these are called psychological constructivism and social constructivism , even though both versions are in a sense explanations about thinking within individuals.

Psychological constructivism: the independent investigator

The main idea of psychological constructivism is that a person learns by mentally organizing and reorganizing new information or experiences. The organization happens partly by relating new experiences to prior knowledge that is already meaningful and well understood. Stated in this general form, individual constructivism is sometimes associated with a well-known educational philosopher of the early twentieth century, John Dewey (1938-1998). Although Dewey himself did not use the term constructivism in most of his writing, his point of view amounted to a type of constructivism, and he discussed in detail its implications for educators. He argued, for example, that if students indeed learn primarily by building their own knowledge, then teachers should adjust the curriculum to fit students’ prior knowledge and interests as fully as possible. He also argued that a curriculum could only be justified if it related as fully as possible to the activities and responsibilities that students will probably have later , after leaving school. To many educators these days, his ideas may seem merely like good common sense, but they were indeed innovative and progressive at the beginning of the twentieth century.

A more recent example of psychological constructivism is the cognitive theory of Jean Piaget (Piaget, 2001; Gruber&Voneche, 1995). Piaget described learning as interplay between two mental activities that he called assimilation and accommodation . Assimilation is the interpretation of new information in terms of pre-existing concepts, information or ideas. A preschool child who already understands the concept of bird , for example, might initially label any flying object with this term—even butterflies or mosquitoes. Assimilation is therefore a bit like the idea of generalization in operant conditioning, or the idea of transfer described at the beginning of this chapter. In Piaget’s viewpoint, though, what is being transferred to a new setting is not simply a behavior (Skinner's “operant” in operant conditioning), but a mental representation for an object or experience.
