I
am sure that you have all been waiting for me to land on this debate.
Quite simply, educators have been experimenting with a range of
protocols for teaching all subjects for the past fifty years with the
enthusiastic support of text book publishers. In many cases the
damage inflicted by poorly considered ideas has been limited and
contained sufficiently to allow the students to progress in some form
or the other.
Let
me explain something else. Starting when I was nine years old, I
read everything I could get my hands on until I met an actual
university library and met my match. I have read hundreds of books
on historical, political, sociological, anthropological, biological,
agricultural, medical, physiological, geological, geographical, and
astrophysical topics as well as a novel or two covering the best of
classical literature for relaxation. That is what I never wrote an
exam on ever and believe me I have missed a few topics. What that
means is that if you hacked your way through a history degree while
reading only the required material, I am hundreds of books ahead of
you and a quick study on most other subjects as well.
What
I did do was master Mathematics simply because it opened all
plausible doors to all knowledge generally. In practice, science is
a collection of data described normally with a mathematical model
dumbed down enough to generate useful results within narrow bounds.
Making the mathematics smarter does not necessarily improve the data,
after all.
The
purpose of education is to train the brain. Improved recall is one
such area, but I am proof that it is barely important except to pass
standard exams. Way more important is to learn and internalize
working algorithms that allow you to interpret the world. That I did
mostly and best through mathematics and how it was taught.
All
algorithms related to arithmetic need to be first internalized,
practiced to establish correct output and then be challenged to reach
a high level of speed before you go forward. You must become fast
with the times table and be forced to calculate in your head.
Internalized properly, that is just what will happen. Better you
will learn and even invent shortcuts if pressed in this way.
Now
you are ready for real mathematics. This should start with a one
term course in Euclid’s Elements in grade ten because it is the
backbone of proof theory. Again promoting speed is wise. This is
not memorization so much as reaching for and assembling the logic
internally.
After
that absorb all the mathematics that is thrown at you. I made my
rebellious son take Grade 12 Calculus in Grade 11, not because he was
ready for it but because he was not ready for it. When it came to
the crunch three months in, I walked him through a demonstration
proof of the differential for some convenient function. When he saw
the two sides of the proof magically match up for QED, the light came
on as it internalized and in two weeks he pounded through the problem
sets and passed the course. He never lost the confidence boost that
gave him afterwards. Confronted with a missed last class problem on
a fourth year final exam, he recalled his skill, structured the most
likely configuration of the necessary equations and aced it.
This
is what learning mathematics is about. It is internalizing the body
of work in front of you. You are training for a sports event and
simple memory games will not bail you out.
Not
everyone can get good at it, but everyone can become progressively
better.
All
education needs to be goal oriented and mathematics doubly so. I
also think that high school graduation must include a sound
preparation in mathematics and at least one core science at minimum.
That mathematics should really include introductory calculus. It is
the best true measure of a graduate’s actual mental ability.
Frustrated
professors convince elementary schools to step back from ‘new math’
and go ‘back to basics’
Moira
McDonald, | 13/09/13
University
of Winnipeg math professor Anna Stokke and two of her colleagues knew
there was “a huge problem,” when they started hearing about
Manitoba grade school students not being taught how to do vertical
addition, carry or borrow numbers, or knowing their times tables.
Then,
two years ago, she and Robert Craigen, a fellow U of W professor, and
Fernando Szechtman a math professor at the University of Regina,
formed WISE Math — the Western Initiative for Strengthening Math
Education. They set up a website with a blog, gave lots of media
interviews and started meeting with government officials to push for
changes in the way math was being taught.
“Then
we started hearing from a lot of parents, from all across Canada,”
said Ms. Stokke, whose group has collected nearly 1,000 signatures
supporting its calls for reform. “It’s a lot of work and it’s a
lot of trouble to advocate for things like this … but our kids are
worth it, because in the end we really need our kids to learn math.”
The
group is now seeing the fruit of its efforts this fall, as Manitoba
rolls out a “back to basics,” revised curriculum for kindergarten
to Grade 8, one explicitly requiring students to learn times tables;
have automatic recall of answers to basic problems such as 30 – 5 =
25, known as math “facts”; and standard algorithms for key math
operations — and perform them without using a calculator.
It
marks a step back from “new math” and “inquiry-based”
teaching approaches that emphasize such things as estimating and
multiple “strategies” in basic calculations — complicated
methods of solving math problems in a bid to develop students’
deeper understanding of how those calculations work. Such approaches
are common across Canada and are part of the Western and Northern
Canadian Protocol (WNCP), a common framework, initiated in 1995 and
revised in 2006, used to develop curriculum in all western provinces,
Canada’s three territories, as well as in Atlantic provinces
including Newfoundland, Nova Scotia and Prince Edward Island.
“It’s
not perfect, but it’s definitely a step in the right direction,”
said Ms. Stokke, who thinks this makes Manitoba the first province to
“walk away from WNCP a bit.”
While
Manitoba continues to be a part of WNCP, its education minister,
Nancy Allan, credits WISE Math’s efforts for helping to drive the
change.
“We
were hearing concerns from parents and we were hearing concerns from
some math professionals,” said Ms. Allan, who called her province
“a leader” in math reform. Besides worrying about students not
learning basic math skills, parents trying to pitch in with their
children’s homework, “were having difficulty helping their young
people because they weren’t able to understand it either.”
Although
standard algorithms “have been used in the past” by teachers, the
revision explicitly states they must be taught, said Blaine Aston,
vice-principal and numeracy specialist at Brandon’s Ecole New Era
School.
“The
clarity in what [teachers] are supposed to teach in each grade level
in terms of math facts is a positive step,” said Mr. Aston.
Winnipeg
parent Laura Lamont says the changes are “a huge relief,”
especially after watching teachers get uncomfortable when asked why
they couldn’t teach students how to add numbers in vertical columns
instead of horizontally.
“The
kids are bright and the teachers are dedicated, but it felt like
everybody had their hands tied behind their back,” said the mother
of twin nine-year-old boys who took matters into her own hands last
year when she enrolled them in Archimedes Math Schools, a non-profit
after-school math program developed by Ms. Stokke. The program itself
dates back to the professor’s efforts to give informal remedial
math help to her own daughter and some of her friends.
But
this is no wholesale dumping of new math teaching. Teaching students
multiple strategies in problem-solving will still be part of the mix,
but the government says it is now striking “the appropriate
balance,” between students’ basic math skills, conceptual
understanding and problem-solving ability. The province also plans to
create a mathematics education advisory committee, update high school
math courses and work with university faculties of education to
improve teacher training in math.
“We’re
not going back to ‘kill and drill,’ that’s not what we’re
trying to accomplish here,” said Ms. Allan. “But there has to be
a basic foundation in regards to adding, and subtracting, and
memorizing math facts [and] knowing how to do math at an early age.”
That
leaves Sherry Mantyka skeptical. Although the math professor at
Newfoundland’s Memorial University said she would welcome a true
back-to-basics approach in her own province’s schools, an
announcement touting just that in 2008 only led to Newfoundland’s
adoption of WNCP. As a result, she continues to work with
hundreds of university students in remedial math programs every
semester. The director of Memorial’s Mathematics Learning Centre
estimates about a 20% failure rate on the university’s math
placement test, required for every student wanting to take at least
one math course.
“They
do not know sums up to 20. They do not know multiplication products
up to 100. … A question like nine into 83,209, they’ll try to do
with repeated subtractions,” she said. One problem, she said, is
that students who resort to using the complicated “strategies”
they’ve been taught in grade school, even for simple math sums, use
up their working memory and are then helpless to solve more
complicated calculations.
She
called the changes in Manitoba “not a bad thing, but is it going to
fix the problem? I doubt it.”
If
we focus on memorization, we’re not going to get there
Even
calling them “back to basics” is “inaccurate,” argued
education professor Ralph Mason, who participated in development of
the revisions. But that’s a good thing, said the University of
Manitoba specialist in math education.
“The
whole idea of rolling these things back to a time when everyone
learned these basic facts didn’t exist,” said Mr. Mason. Previous
methods that have focused on memorization and rote performance are
“strategies we know never worked,” and left some students
struggling.
But
Ms. Stokke complains that “there’s always this false dichotomy
that gets set up where they say, ‘We want kids to learn with
understanding and you want skills.’ Well, that’s ridiculous. They
should have both. You don’t start neglecting one side of it in
favour of the other.”
Alberta
has had a key hand in developing WNCP and uses it as a framework for
its own curriculum. Christine Henzel, director of mathematics, arts
and communication for Alberta’s education department, and who has
worked on the development of WNCP in the past, said she could not
speak to whether Manitoba’s changes signify a rejection of any
aspect of WNCP, but said it is expected that all provinces using it
will adapt it to their local needs.
WNCP
is based on research, she said, and is aimed at providing students
with real world math skills so that they understand how and when to
apply the math facts they know.
“If
we focus on memorization, we’re not going to get there,” she
said.
Another
question arises, if the WNCP is so bad, how come Alberta, which uses
it, remains a Canadian leader when it comes to international testing?
Ms.
Stokke and, her fellow U of W professor, Mr. Craigen argue that in
fact even Alberta and other provinces such as British Columbia have
seen their math achievement drop in outside assessments since WNCP
came on the scene.
“Every
jurisdiction under WNCP has shown steadily decreasing assessment
outcomes since the introduction of the WNCP curriculum,” said Mr.
Craigen.
Meanwhile,
there are signs parents outside of Manitoba are also searching for
more help with building their children’s essential math skills,
says Doretta Wilson, executive director for the Ontario-based Society
for Quality Education, an advocacy group pushing for more
back-to-basics approaches. The province’s student testing agency
recently reported a five-year decline in Grade 3 and 6 students’
math skills and a growing number of students seeing a drop in their
achievement between Grade 3 and Grade 6.
“I
can tell you through our own website, our math worksheets are our
highest in-demand resource,” said Ms. Wilson. “And it doesn’t
look like the tutoring centres are going to go out of business any
time soon in Ontario.”
