Should all countries use
the Shanghai maths method?
By Harry Low, BBC World Service
When the Chinese city of Shanghai took part in the three-yearly Pisa
test of 15-year-olds' academic ability in 2009 and 2012 it topped the
table in maths, leaving countries such as Germany the UK and the US -
and even Singapore and Japan - trailing in its wake. What is its secret?
The life of a teacher in a Shanghai primary school differs quite a bit
from that of teachers in most other countries. For one thing each
teacher specialises in a particular subject - if you teach maths, you
teach only maths.
These specialist teachers are given at least five years of training
targeted at specific age groups, during which they gain a deep
understanding both of their subject and of how children learn.
After qualifying, primary school teachers will typically take just two
lessons per day, spending the rest of their time assisting students who
require extra help and discussing teaching techniques with colleagues.
"If you compare that to an English practitioner in a primary school now,
they might have five days of training in their initial teacher training
year, if they're doing the School Direct route, for example," says Ben
McMullen, head teacher of Ashburnham Community School, London.
"They might have some follow-up training during the first or second year
of training - inset, staff meetings etcetera - but there's no comparison
between the expertise of someone who's had five years of training in a
specific subject to someone who's had only a handful of days."
It's a similar story in secondary school, where teachers spend less time
in the classroom with pupils than they do on planning and refining
lessons.
There are other differences too. School days are longer - from 07:00
until 16:00 or 17:00. Class sizes are larger. And lessons are shorter -
each is 35 minutes long, followed by 15 minutes of unstructured play.
There is no streaming according to ability and every student must
understand before the teacher moves on. In the early years of school
basic arithmetic is covered more slowly than in the UK, says McMullen,
who has travelled to Shanghai in one of the groups of British teachers
sent every year by the Department of Education to watch and learn.
"They looked at our curriculum and were horrified by how much we were
trying to teach," he says.
"They wouldn't teach fractions until year four or five. By that time,
they assume that the children were very fluent in multiplication and
division.
"This is essentially a 'teaching for mastery' approach: covering less
and making smaller incremental movements forward, ensuring the class
move together as one and that you go over stuff again and again until
it's truly understood."
It seems that other cities in mainland China may not be on quite the
same level as Shanghai. In the 2015 Pisa test Shanghai was bundled
together with Beijing, Jiangsu and Guangdong, and they jointly came
fifth in maths, behind Singapore, Japan, Taiwan and Hong Kong.
It's also been suggested that Shanghai's results in previous years could
have been skewed by the failure to include about a quarter of pupils in
the city. However Pisa insists its results demonstrate that the children
of menial workers in Shanghai outperform the children of professionals
in the West.
This is one of the key attractions of the system - it helps poor
children realise their potential, increasing social mobility. But there
are also drawbacks, according to Henrietta Moore of the Institute for
Global Prosperity at University College London.
"The idea there is that effort brings rewards and so you will get this
totally driven sort of idea but what you don't get - and what Chinese
maths teachers are currently grappling with - is this creative
problem-solving that requires space and mulling and dwelling," she says.
"We're actually much better at this in the UK and they're trying to
develop that and learn from us."
Another criticism of the system is that parents work children too hard.
An estimated 80% of students receive private lessons outside school.
"One of the downsides of parental interest in education is they get
competitive - they're more competitive than the children - so they want
to have all these extra classes," says Moore.
So is this a system other countries would do well to adopt?
"I would adopt the idea that anyone who teaches maths needs a deep
understanding of the conceptual building of maths and a deep
understanding of how children learn that," says Anne Watson, emeritus
professor of maths teaching at Oxford University. "I would also want to
take on board the idea of high expectations for everyone."
Online entrepreneur Martha Lane-Fox is also a fan.
"Two things really appeal to me about this," she says. "The idea that
everyone can be more of a maths master than I think we believe here in
the UK. I also really like the incredible attention to the micro-detail.
I'm really interested in this notion of incrementalism and moving things
on in small chunks.
"The fundamentals of this policy are right and it's incredibly inspiring
to think everybody can become more freed up by maths."
Ben McMullen's primary school has already been borrowing some of
Shanghai's ideas, he says.
There is no streaming, pupils are interacting more and there is a
"different atmosphere" in class.
"The younger learners
moving up the school have an incredibly robust sense of maths,
calculation and of concept," McMullen says. |
