children’s numerical skills
people appear to born to compute. The numerical skills of children develop
so early and so inexorably that it is easy to imagine an internal clock of
mathematical maturity guiding their growth. Not long after learning to walk and
talk, they can set the table with impress accuracy---one knife, one spoon, one
fork, for each of the five chairs. Soon they are capable of nothing that they
have placed five knives, spoons and forks on the table and, a bit later, that
this amounts to fifteen pieces of silverware. Having thus mastered addition,
they move on to subtraction. It seems almost reasonable to expect that if a
child were secluded on a desert island at birth and retrieved seven years later,
he or she could enter a second enter a second-grade mathematics class without
any serious problems of intellectual adjustment.
Of course, the truth is not so simple. This century, the work of cognitive
psychologists has illuminated the subtle forms of daily learning on which
intellectual progress depends. Children were observed as they slowly
grasped-----or, as the case might be, bumped into-----concepts that adults take
for quantity is unchanged as water pours from a short glass into a tall thin
one. Psychologists have since demonstrated that young children, asked to count
the pencils in a pile, readily report the number of blue or red pencils, but
must be coaxed into finding the total. Such studies have suggested that the
rudiments of mathematics are mastered gradually, and with effort. They have also
suggested that the very concept of abstract numbers------the idea of a oneness,a
twoness , a threeness that applies to any class of objects and is a prerequisite
for doing anything more mathematically demanding than setting a table-----is
itself far from innate |
