I don't know about "standards" in the "hard sciences" and math but I think
the issue of standards overall is quite misplaced.

Standards at least as presented below or by the back to the basics crew
refers to a highly individualized approach to knowledge and learning.

In fact, most current approaches and particularly those that are linked into
broad concerns for national innovation and productivity are recognizing that
knowledge and learning are highly contextual and even more so when they are
looked at in relation to their application rather than their "inculcation".

Nobody (well almost nobody) learns alone (just as nobody works alone or
"innovates" alone) and those who do are generally understood to suffer the
consequences.

Knowledge is in its essence collaborative (the creation/re-creation of
meaning) so to attempt to impose highly individualized standards as
operationalized in formal tests makes about as much sense as attempting to
hold back the dikes of plagiarism now that we have a Google (whoops that's
another but overlapping set of Canutes)...

Subject: Being treated with contempt


It is a paradox that the developed countries, with increasing needs for
doctors, scientists, engineers, mathematicians and suchlike, are
increasingly less able to supply them in sufficient numbers as the years go
by. That's why several countries, particularly America and England (but
also France and Germany, and perhaps Canada for all I know), are having to
import increasing numbers of these valuable specialists from abroad,
usually from less developed countries -- which, of course, become even more
deprived of the skilled human resources they badly need for themselves.

At the same time, governments in developed countries are pretending that
they themselves are increasing the supply of specialists from their own
education systems. To help persuade more schoolchildren to move away from
arts and general subjects, exam boards in those countries have been
steadily reducing the difficulty of the science examinations needed for
university entrance. A corollary of this is that examination results have
seemed to have improved steadily over the years -- attributed to "higher
quality teaching".

Anybody like me who dares to say that the standards have, in fact, declined
enormously over their lifetimes are jumped on from a great height by
teaching unions, politicians, exam boards and others who are professionally
involved in the business.

Indeed (as will be seen below), the educational professionals say we are to
"be treated with contempt"

There's a huge amount of "spin" involved here. I reckon that for every
critical article that appears in a newspaper then at least four or five
times more exposure is given to presentations which suggest that all is
going swimmingly. This reassuring news is all too readily accepted by large
numbers of school teachers, children and their parents. Of course, the
grounds for saying that standards are improving are never tested
scientifically.

However, in his own modest way, one university physics lecturer has done so
in this country and some FWers might be interested in an article of his
which appeared in today's Daily Telegraph:

FIGURES THAT JUST DON'T ADD UP
David Milstead

As a lecturer in physics, I know there is no such thing as a paradox --
only apparent paradoxes that can always be explained by a careful
examination of the whole problem. Applying this philosophy, we tackled an
educational paradox within our department. How is it that incoming
undergraduates have better qualifications but seem to know less than in
previous years?

A[dvanced]-level pass rates in physics and maths have risen almost
continuously for more than a decade. Teachers' unions and the Government
attribute this to improved teaching and more assiduous pupils. Reports from
the Qualifications and Curriculum Authority (CQA), the quango that monitors
school examinations, deny any dumbing down.

Such reassurances sit uneasily with the "support maths" courses that now
feature in most physics and engineering degrees. Degrees have also had to
be extended to four years to cope with ill-prepared students and maintain
academic standards. We investigated whether a less demanding physics
A-level could be responsible for any of this. The QCA check standards of
examinations by asking professionals to make judgements on question
difficulty. We chose a much less subjective approach and set our
undergraduates special tests. We also analysed the changing mathematical
content of the questions.

The usual smikescreen put up by the CQA is to complain that syllabus
changes make a comparison over time difficult. Developments have taken
place in physics in recent years that are now rightly in the A-level
syllabus.  However, these are largely peripheral, and the bulk of the
subject has remained unchanged for many years.

To ensure comparability we focused mainly on core areas of physics. Topics
such as Newton's laws and electricity and magnetism remain at the heart of
the physics A-level. The standard of the examination cannot but depend on
their treatment.

A-level papers of one of the largest exam boards were selected. These dated
from 1983 to the present day. The most striking fact was the purging of
maths. The average number of mathematical steps needed to answer a question
was constant at about four until the early 1990s. Two mathematical steps
are typically needed now. Remaining marks are awarded for hand-waving
explanations of physicla phenomena (much like the old O[rdinary]-level, in
fact).

This may not seem such a terrible development. However, dexterity in maths
is central to understanding physics. Newton would be remembered as a
speculative philosophy if his only contribution was noting that a force
called gravity pulled an apple to earth. Fortunately for mankind he was
also a great mathematician. His laws of motion allow us to calculate the
speed and trajectory of the apocryphal apple that hit his head. They are
also used to send interplanetary probes with pinpoint accuracy across vast
areas of space. without maths, physics loses its rigour and much of its
usefulness.

We mneasure the difficulty of the new, reduced-maths physics A-level with
class tests. Assurances of anonymity and a raffled bottle of wine pesuaded
55 first-year physics students to take part. Older (pre-1992) and more
recent (post-1997) questions were selected. Both sets of questions covered
the same topics and required the same basic knowledge. Scores were on
average 1.6 times higher for the recent questions.

We also repeated the exercise with second year students. As expected, they
performed much better overall, although even they managed the older
questions less well. It is hard not to conclude that teh questions are not
as difficult as they used to be. This contradicts the official teachers'
union line. David Hart of the National Association of Head Teachers
believes that doubters like me, the Institute of Directors and anybody else
daring to state the obvious should be "treated with contempt".

QWe inverstigated whether these opinions were shared on the front line. A
questionnaire on the changing nature of A-level physics was completed by a
representative sample of 72 physics teachers in the North-West. Mr Hart
must think that 60% of these teachers contemptible. They said thaty less
demanding questions were the most significianbt factor in the rise in pass
rates. Only 10% attributed the rise to better teaching. In addition only
40% of teachers thought that the brightest pupils were still being
challenged.

On balance, I think we resolved the paradox posed at the start of this
article. The physics A-level is not what it used to be.
