Bruner (1960) believes that
culture mediates a learner’s cognitive development as represented by three modes
through which knowledge is acquired: enactive, iconic, and symbolic. In the
enactive representation, an individual learns by doing and by recalling past
events. Iconic representations are internally constructed through visualized and
other sensory organizations. Symbolic representations are manifested through
languages, both verbal and numerical. The learner’s social and cultural context,
according to Bruner (1986, 1990), influences how, when, and what learning
becomes knowledge. Cultural influences, however, are not necessarily conscious
to the individual. Since an instructional designer’s knowledge of enactive,
iconic, and symbolic representations may differ from that of the intended
learner, Bruner recommends that all instruction begin with the learner’s
experiences and contexts.
