This story has a point, I hope:
My husband was commenting at dinner one night about a fellow worker who was
in danger of losing his job due to a downsizing of the organization.(We all
know about downsizing. It's where people lose their jobs so that
corporations can continue to pay phenomenal salaries to the top management
and keep the stockholders happily making money.) The organization is
involved in commercial use of scientific research in geology. He was
offered a slightly different position but he had to pass an examination in
mathematics in order to qualify for that position. It was not an advanced
math exam: just what we would call arithmetic and understanding the basic
operations as applied to scientific notation, the meanings of prefixes like
milli, pico, nano, deci, centi and so forth. This man was frightened. He
had been perfectly competent in his former scientist-support position. But
that position was simply being eliminated. Now he needed to demonstrate an
easy facility with mathematics...Yes, the company has computers...very
expensive, elaborate and all over the place computers. But his employer
felt it was essential that he demonstrate competence in basic mathematics in
order to be allowed to continue to provide for his family by working at this
company. When I heard of his plight I offered to work with him in order to
prepare for this exam. You can be sure we did lots of problems quite
repetitively. I also tried to *focus* on the meaning of the operations.
But he needed to know efficient algorithms to get correct answers fast. He
needed to memorize the terms that he would need to communicate accurately
with the community. It wasn't fun. He worked very long and hard at it. But
it was more fun than "losing his home and not eating".

Was he unique in this experience? I don't know. Did he at one time think
he wouldn't need all that stuff like sin, cos(A-B)? I would guess,

This is a reality that I try to keep before me as I work to implement change
in mathematics instruction. Yes, keep the focus on understanding and
meaning. Help people to see that they can construct mathematics. Teach so
they are in control of the material they are learning. But then carry that
understanding forward to some form of completion, with competence, accuracy,
efficiency and rigor. With the necessary shift in focus toward problem
solving and constructivism some (myself included) have lost sight of the
necessity to carry the job to completion. Where that line of completion is
at this time I am not quite so sure. I'm still thinking about this.
