Jerome Bruner - Developmental Psychology

Developmental Psychology

Beginning around 1967, Bruner turned his attention toward the subject of developmental psychology. Bruner studied how children learned: he coined the term "scaffolding" to describe how children often build off the information they have already mastered.

In his research on the development of children (1966), Bruner proposed three modes of representation: enactive representation (action-based), iconic representation (image-based), and symbolic representation (language-based). Rather than neatly delineated stages, the modes of representation are integrated and only loosely sequential as they "translate" into each other. Symbolic representation remains the ultimate mode, for it "is clearly the most mysterious of the three."

Bruner's theory suggests it is efficacious when faced with new material to follow a progression from enactive to iconic to symbolic representation; this holds true even for adult learners. A true instructional designer, Bruner's work also suggests that a learner (even of a very young age) is capable of learning any material so long as the instruction is organized appropriately, in sharp contrast to the beliefs of Piaget and other stage theorists. (Driscoll, Marcy). Like Bloom's Taxonomy, Bruner suggests a system of coding in which people form a hierarchical arrangement of related categories. Each successively higher level of categories becomes more specific, echoing Benjamin Bloom's understanding of knowledge acquisition as well as the related idea of instructional scaffolding.

In accordance with this understanding of learning, Bruner proposed the spiral curriculum, a teaching approach in which each subject or skill area is revisited at intervals, at a more sophisticated level each time.
