Making Math Education
Even Worse
American students are already struggling
against the competition. The Common Core won't help them succeed.
By Marina Ratner in
the Wall Street Journal
I first encountered
the Common Core State Standards last fall, when my grandson started sixth grade
in a public middle school here in Berkeley, Calif. This was the first year that
the Berkeley school district began to implement the standards, and I had heard
that a considerable amount of money had been given to states for implementing
them. As a mathematician I was intrigued, thinking that there must be something
really special about the Common Core. Otherwise, why not adopt the curriculum
and the excellent textbooks of highly achieving countries in math instead of
putting millions of dollars into creating something new?
Reading about the new
math standards—outlining what students should be able to learn and understand
by each grade—I found hardly any academic mathematicians who could say the
standards were higher than the old California standards, which were among the
nation's best. I learned that at the 2010 annual conference of mathematics
societies, Bill McCallum, a leading writer of Common Core math standards, said
that the new standards "would not be too high" in comparison with
other nations where math education excels. Jason Zimba, another lead writer of
the mathematics standards, told the Massachusetts Board of Elementary and
Secondary Education that the new standards wouldn't prepare students for
colleges to which "most parents aspire" to send their children.
I also read that the
Common Core offers "fewer standards" but "deeper" and
"more rigorous" understanding of math. That there were "fewer
standards" became obvious when I saw that they were vastly inferior to the
old California standards in rigor, depth and the scope of topics. Many
topics—for instance, calculus and pre-calculus, about half of algebra II and
parts of geometry—were taken out and many were moved to higher grades.
As a result, the
Common Core standards were several years behind the old standards, especially
in higher grades. It became clear that the new standards represent lower
expectations and that students taught in the way that these standards require
would have little chance of being admitted to even an average college and would
certainly struggle if they did get in.
It remained to be seen
whether the Common Core was "deeper" and "more rigorous."
The Berkeley school district's curriculum for sixth-grade math was an exact
copy of the Common Core State Standards for the grade. The teacher in my
grandson's class went through special Common Core training courses.
As his assigned
homework and tests indicate, when teaching fractions, the teacher required that
students draw pictures of everything: of 6 divided by 8, of 4 divided by 2/7,
of 0.8 x 0.4, and so forth. In doing so, the teacher followed the instructions:
"Interpret and compute quotients of fractions, and solve word problems
involving division of fractions by fractions, e.g., by using visual fraction
models and equations to represent the problem. For example, create a story
context for 2/3 divided by 3/4 and use a visual fraction model to show the
quotient . . ."
Who would draw a
picture to divide 2/3 by 3/4?
This requirement of
visual models and creating stories is all over the Common Core. The students
were constantly told to draw models to answer trivial questions, such as
finding 20% of 80 or finding the time for a car to drive 10 miles if it drives
4 miles in 10 minutes, or finding the number of benches one can make from 48
feet of wood if each bench requires 6 feet. A student who gives the correct
answer right away (as one should) and doesn't draw anything loses points.
Here are some more
examples of the Common Core's convoluted and meaningless manipulations of
simple concepts: "draw a series of tape diagrams to represent (12 divided
by 3) x 3=12, or: rewrite (30 divided by 5) = 6 as a subtraction
expression."
This model-drawing
mania went on in my grandson's class for the entire year, leaving no time to
cover geometry and other important topics. While model drawing might
occasionally be useful, mathematics is not about visual models and "real
world" stories. It became clear to me that the Common Core's
"deeper" and "more rigorous" standards mean replacing math
with some kind of illustrative counting saturated with pictures, diagrams and
elaborate word problems. Simple concepts are made artificially intricate and
complex with the pretense of being deeper—while the actual content taught was primitive.
Yet the most
astounding statement I have read is the claim that Common Core standards are
"internationally benchmarked." They are not. The Common Core fails
any comparison with the standards of high-achieving countries, just as they
fail compared to the old California standards. They are lower in the total
scope of learned material, in the depth and rigor of the treatment of
mathematical subjects, and in the delayed and often inconsistent and incoherent
introductions of mathematical concepts and skills.
For California, the
adoption of the Common Core standards represents a huge step backward which
puts an end to its hard-won standing as having the top math standards in the
nation. The Common Core standards will move the U.S. even closer to the bottom
in international ranking.
The teaching of math
in many schools needs improvement. Yet the enormous amount of money invested in
Common Core—$15.8 billion nationally, according to a 2012 estimate by the
Pioneer Institute—could have a better outcome. It could have been used instead
to address the real problems in education, such as helping teachers to teach
better, raising the performance standards in schools and making learning more
challenging.
