Adult learning theory, first described by Malcolm Knowles in the early 1970
s, is based on a number of apparently self evident axioms about how adults
learn. The fundamental assumptions remain largely untested, and a critical
analysis suggests that they may be largely a product of the environment in
which adults find themselves rather than of any innate differences between
adults and children. What evidence does exist suggests that one critical co
mponent of adult learning, self-assess-ment, is not easy. Further, while st
udents can learn the skills to learn on their own (i.e., can acquire self-d
irected learning skills), this does not translate into greater competence,
in either the short or long term. Uncritical reliance on the principles of
adult: learning may have detrimental consequences, particularly in the doma
in of maintenance of competence.
