THE COMING DISASTER IN SCIENCE EDUCATION IN AMERICA BY JOHN SAXON:
The Coming Disaster In Science Education In America
By John Saxon
Written in 1993
I believe that the present disaster in science education in America will be
drastically exacerbated in the next decade because of recent actions of the
National Council of Teachers of Mathematics. These actions are capricious at
best and approach total irresponsibility at worst. This organization has
decided, with no advanced testing whatsoever, to replace preparation for
calculus, physics, chemistry, and engineering with watered-down mathematics
curriculum that will emphasize the teaching of probability and statistics and
will encourage the replacement of the development of paper-and-pencil skills
with drills on calculators and computers. This drastic shift in emphasis will
leave American students bereft of the detailed knowledge of the parts that
permit the whole to be comprehended.
America is on the road to becoming a follower in technology and science rather
than a leader. Our captains of industry tell us that they are at a disadvantage
in worldwide competition because our labor pool is mathematically incompetent.
This incompetence has been documented by recent tests which show that eighty-two
percent of our seventeen-year-olds do not know what the word area means and also
by international test results wherein American students scored near the bottom
of the students in the nations tested. The engineering and physics departments
of American universities are overrun with foreign-born students and teachers
because most American university students do not know the mathematics necessary
to be successful in engineering and physics.
To correct this situation, we need a no-frills national mathematics program that
concentrates on precocious fundamentals. We have to get our best students
(thirty percent) through advanced placement calculus in high school and get the
next ability group (forty percent) prepared for calculus as college freshmen.
The rest of the students should master the fundamentals of mathematics that are
required to be productive members of our labor pool, enabling us to compete with
Europe and the Oriental nations. It can be done. Jaime Escalante, whose
exploits were documented in the film Stand and Deliver, had 150 students in
advanced placement calculus at Garfield High School in 1988-1989. This school
is in the heavily Hispanic East Los Angeles area. If all of our schools had the
same percentage of students in calculus, there would be no crisis in American
scientific education.
Rather than implement a program to prepare students for engineering and the hard
sciences, as well as for advanced mathematics, the mathematics education
“experts” of the NCTM have come up with a document called Standards for School
Mathematics. This document makes absolutely no mention of preparing students
for chemistry. It makes no mention of preparing students for physics or
engineering. The document even denigrates the idea of preparing students for
calculus. The document discusses the mathematics needed for “business,
economics, linguistics, biology, medicine and sociology“: and says “however, the
fundamental mathematical ideas needed in these areas are not necessarily those
studied in a traditional algebra-geometry-precocious sequence, a sequence
designed with engineering and physical science applications in mind.”
Our country is at risk and the NCTM is now insisting on a radical, totally
untested shift in the mathematics curriculum that veers away from preparing
students for calculus and the hard sciences. The Standards details how this
watering-down process is to be carried out. Students will devote less attention
to memorizing subtraction facts and will have less paper-and-pencil practice
with fractions and les paper-and-pencil practice with long division. Books will
de-emphasize the teaching of radical expressions, conic sections,
paper-and-pencil solutions of trigonometric equations, and the solutions of the
old-fashioned fundamental word problems that have been used historically to
teach the concepts and skills necessary to solve all problems.
The scenario is almost an exact duplicate of the scenario of the “new math”
disaster which was caused by the enthusiastic and hasty implementation of
another totally untested set of recommendations made by another committee of
“experts.” The first scenario was in the 1960’s and the committee was called
the School Mathematics Study Group and was chaired by Professor Begle of Yale
University. This group was studying ways of improving secondary mathematics
education in America when the Russians first launched Sputnik. A national panic
ensued because obviously “America is falling behind the Russians in math and
science.” The recommendations of this committee were used as the basis of a
paperback series called SMSG or the “new math.” The radical, untested shift in
emphasis contained therein was forced into every American classroom because
anyone who objected to this nonsense was branded as being unpatriotic.
Most of us are afraid of people who know mathematics because each of us feels
that our knowledge of mathematics is inadequate. Thus we fear that someone who
does know mathematics can somehow peer into our souls and detect this gross
inadequacy of which we are so ashamed.
This is the reason that no one, with the exception of the mathematician Morris
Kline, had the gumption to question the arrant nonsense emphasized in the “new
math” books, nonsense that knowledgeable authorities have refrained from
speaking out against even to the present day. Many of our prominent “experts”
in math education today were gofers for the originators of the “new math”” and
have built their careers espousing the “new math” philosophy. To admit that the
“new math” was a horrendous error would cast aspersions on their careers as
experts in math education. The National Council of Teachers of Mathematics has
backed the “new math” philosophy for thirty years and to suggest that SMSG was a
terrible blunder would be a stain on the escutcheon of this organization.
In the late 1970’s it became apparent to some of the insiders that all was not
well in math education. Calculators and computers for the classroom use had
been recommended since 1972. Neither of these instruments had been shown to be
effective at that time, but a drowning man will grasp at any straw. The NCTM
felt that leadership was necessary, so they threw together a document called
“The Agenda for the Eighties,” in which it was recommended again that
calculators and computers be used in classrooms and that the emphasis in math
classes be shifted to “problem solving of real-world problems.”
The efficacy of the use of calculators in elementary schools still had not been
proved and many people questioned the wisdom of introducing calculators before
students had become proficient with paper-and-pencil exercises. In 1984, a
meta-analysis of all the tests on the use of calculators in elementary schools
was compiled. One of the tests in this analysis showed that calculators were
significantly damaging to the calculating ability of average fourth-graders.
This one significant negative finding would cause a prudent man to proceed with
caution. But the NCTM ignored this finding and recommended that calculators be
made available in every elementary grade and that “students be allowed to decide
when it was better to estimate, to use paper and pencil, or to use a
calculator.” They even used the meta-analysis to justify this recommendation
and said that the findings for the use of calculators outweighed the finding
against the use of the calculators. So they again heavily recommended
calculators for use in elementary schools. Can you imagine what would happen to
the Federal Drug Administration if it approved a drug that was damaging only to
average ten-year-olds?
Had the NCTM said that this finding was enough to require further tests and had
it conducted large scale tests for several years in inner city schools, rural
schools, and suburban schools with no negative findings and with very positive
findings, a foundation for a tentative approval of calculators in elementary
schools might have been established.
I dwell on the calculator issue, not because it is so important, but to
emphasize the mentality of the committees of experts who have been and are
directing mathematics education in America. Jack Nicklaus is an expert golfer
because he has won more major golf tournaments than any other man. Boris Becker
and Steffi Graff are members of the pantheon of kings and queens of tennis
because of their successes. Only in American mathematics education do people
with a track record of abject failure arrogate the title of “expert.” We have
implemented their recommendations for years and years without requiring proof of
efficacy first. I say that the time has come to question the experts,
especially since they have asked the country to join them in another untested
and questionable shift in pedagogy that I believe will cause great harm to
America and should be called the “new new math.”
The major thrust of this program will be an attempt to teach students the art of
solving “real-world problems” without first teaching the concepts and skills.
The idea is to let skill development and concept understanding evolve from the
use of the concepts and skills in the solutions of real-world problems. The
initial concept understanding is supposed to result from the explanation of the
teacher (which seldom occurs) and then the emphasis is to be on applications of
the concept. Of course, the “experts” believe that there is no need to prove
that this approach is feasible before it is forced on the students of America.
They have talked almost every responsible organization in American education
into endorsing the Standards. They list the endorsement of forty organizations,
including the National Association of Secondary School Principals, the National
Society of Professional Engineers, and the American Association of Physics
Teachers. Even the astronaut Sally Ride has endorsed the Standards. Who could
be against standards for American mathematics education? I assume that these
people endorsed the program without fully realizing what they were endorsing.
Certainly everyone is in favor of doing something about the sad state of math
and science education in America and, as do our “experts,” they grasp at any
straw.
I began visiting Jaime Escalante soon after his success in teaching calculus in
Garfield High School in East Los Angeles was reported by Reader’s Digest. Mr.
Escalate sees high school calculus as a lever that Hispanic children can use to
enable them to get college scholarships in engineering and thus to become full
participants in our technological society. Mr. Escalante is certainly in favor
of standards for his students. How does it happen that he was quoted in the
press as saying that “whoever wrote [the standards] must be a physical education
teacher”? It is because the NCTM Standards comprises another flight of fancy by
putative experts. These “experts” recoil in anger when asked why they should
not prove the expected results of their recommendations before they are
implemented. Jaime Escalante has proved his methods before the entire world.
Why should the NCTM not do the same? I was happy to see Mr. Escalante’s
comment. I had read the Standards carefully and was convinced that they had
been compiled behind the looking glass with Alice at the Mad Hatter’s Tea Party.
The document is replete with nonsense such as the following:
‘Our premise is that what a student learns depends to a great degree on how he
or she learned it. For example, one could expect to see students recording
measurements of real objects, collecting information and describing their
properties using statistics and exploring the properties of a function by
examining its graph. This vision sees students studying much of the same
mathematics currently taught but with quite a different emphasis. It also sees
some mathematics being taught that in the past has received little emphasis in
schools.’
This premise and vision gibberish is followed by statements that students should
learn to value mathematics, become mathematically confident, become mathematical
problem solvers, learn to communicate mathematically, and learn to reason
mathematically. If one reads the entire Standards document carefully, it is
really difficult to decide whether it was written behind the look glass by the
Red Queen or if it was written by a physical education instructor, as Jaime
Escalante contends.
We need to get as many students as we can through calculus in high school. We
need students who are competent in the use of fractions, decimals, mixed
numbers, percent, and ratios. We need students who know trigonometry and
analytic geometry. We need a work force that allows Americans to compete
successfully in a technological world. We do not need guidelines that recommend
leaving student ill-prepared for chemistry and physics and that ridicule
preparation for calculus.
This violent shift in emphasis recommended by the NCTM stems from the failure of
the experts to find a way to teach the concepts and skills first. The first
draft of the Standards stated that because we have been unable to teach the
concepts and skills first and then teach the applications, we must have been
trying to do it the wrong way. Thus we should try to do it the other way. We
should try to teach the concepts and skills through the study of real-world
problems. Can you believe this off-the-wall reasoning?
I was aghast at this wild surmise and was chagrined that one of the authors of
the Standards deleted this statement before the final version was printed. This
statement was a dead giveaway to the pie-in-the-sky fuzzy thinking that lay
behind the whole document. America has depended on our “experts” in mathematics
education for 30 years and they have let us down. Now they propose that we
accept a set of nebulous recommendations that are totally unproven. The book
companies will work feverishly to publish books that try to meet the guidelines
and the result will be an acceleration of the disaster in mathematics and
science education. It will take at least ten years for the full extent of the
coming disaster to become apparent. College math enrollment will decline and
the number of American students in physics and engineering will decline even
further. And no one will be to blame. They will all say, “It wasn’t my fault.”
I guess that is the advantage of being just a member of a “committee of
experts.”
The mathematical knowledge required for success in chemistry, physics, and
engineering has not changed. High school students avoid chemistry, not because
they fear studying electron orbital, but because they lack the concepts and
skills necessary to work problems that involve chemical combinations by weight
and other problems that require mastery of the basic manipulatory skills of
algebra and the basic concepts of trigonometry. An article discussing the poor
mathematical abilities of physics students at the University of Houston appeared
in the December 1989 issue of the Physics Teacher. It reported that only
one-fifth of these students knew how to handle trigonometric functions of large
angles and only one-third could solve parametric equations or work simple
problems that required two steps. It stated flatly that students are not coming
to college prepared for the algebra and trigonometry required for success in
physics.
The Standards document stresses that there must be a shift in mathematics
education away from practicing problems categorized by type, such as coin
problems, age problems, digit problems, work problems, and
trains-leaving-Detroit-at-midnight problems. There is absolutely no way that
this shift in emphasis can be justified. These problems have been developed by
teachers over the years to teach the thought processes and skills that are
necessary to solve other problems that are new and strange. The document says
that “type” problems should be replaced with “non-standard problems” and with
“open-ended problems” and “extended problem-solving project.” The idea of
non-standard problems is ludicrous. Don’t the authors of the Standards realize
that all of the problems in the first course in algebra are non-standard to
students who have never studied algebra before? “Non-standard” must mean
problems that the algebra teachers have never seen before or tried before or
used as teaching tools before. Throwing out a tried-and-true method and
replacing it with something new that is untested is the height of
irresponsibility.
The answer to the problem just outlined lies in the market place, the unique
entity that allows the free enterprise system to work effectively. If secondary
schools in America demand books that prepare students for physics, chemistry,
engineering, and other mathematically-based disciplines, the major book
companies will publish books that do the job. Science teachers should insist
that the book companies to extensive testing of their math and science books and
present proof of efficacy before books are considered for purchase. The books
should prepare the students for the hard sciences and should also encourage the
development of critical thinking and the use of higher-order though processes.
The science teachers must use all their powers of persuasion to see that their
schools adopt only math books that have been tested and proved to be superior.
Books that follow highly recommended pedagogy but have not been proved to be
effective should be rejected out of hand. Book companies are in business to
make a profit. Period. But every other American company is in business for
the same reason, and it is unfair to require book companies to be more
altruistic than other companies. Book companies will product and test books
that can be used effectively in the classroom if that is what is required to
stay in business and make a profit. Science teachers can cause the revolution
we need in American mathematics educations by seeing that their schools purchase
only mathematics books that do the job. What a simple solution to a very
complex problem!!!
