In the study of learning differences, attention has recently been give
n to holistic, dialectical concepts of development and learning such t
hat cognitive processes are defined and investigated relative to their
dynamic, transforming, hierarchically organized systems of energy. Su
ch a point of view is consistent with the new science of life in which
matter has, as its essence, active, dynamic forms of hierarchically o
rganized energy that are bound within fields. The hierarchical nature
of energy forms is due to their organization into distinct systems of
order with varying levels of complexity. Openings for energy exchanges
within and between individual energy systems are created from perturb
ations as systems interact with the environment and result in the reor
ganization and expansion of activity that give birth to more complex s
tructures. Piaget's description of cognitive processes as dynamic, tra
nsforming, hierarchically organized systems of energy that evolve in i
nteraction with the environment calls into question the validity of cu
rrent reductionist assumptions regarding learning differences, At the
same time, Piaget's insights (and those of similar progressive thinker
s) provide a foundation upon which to build an understanding of learni
ng differences consistent with the principles of the new science of li
fe.
