Changing students' perceptions

Changing teachers' perceptions
of mathematics and of teaching mathematics
A group of teachers involved
in embedding NRICH tasks
into their everyday practice were keen to challenge common
perceptions of mathematics and of teaching and learning
mathematics. In this article, the teachers share what they are
doing to change perceptions in their schools.
What were we trying to
achieve?
We wanted students to feel positive about learning and doing
mathematics through engaging lessons.
Whilst the focus on changing perceptions was initially targeted
at learners it became apparent that teachers needed to consider
the messages they convey through the way they behave in the
classroom, and their expectations of learners. This is
dependent on their attitudes towards and beliefs about
mathematics and learning mathematics.
NRICH's aim was to offer support that would enable all teachers
to provide rich mathematical experiences that highlighted the
value of mathematical thinking to all their students. We wanted
students and teachers to appreciate that:
- it is not acceptable to say 'I am no good at maths'
- mathematics learning need not depend on teachers
demonstrating methods in advance of students practising
techniques
- doing mathematics offers an opportunity to be creative,
and to share ideas and opinions
- it is acceptable to allow students to flounder a little
when solving non-routine problems
- although mathematics can be hard, everyone can experience
success
- mathematics is more than a series of isolated and
unconnected pieces of knowledge. See, for example, Paul
Andrews' article Angle
Measurement: an Opportunity for Equity
- mathematics is not just about answers and results, but
also about strategies and approaches
- mathematics has cross-curricular connections
- students' perceptions of mathematics can be changed. See,
for example, Nardi and Steward's accounts of mathematics
being 'TIRED' (Nardi and Steward, 2002a, 2002b, 2003).
How did we try to achieve
this?
The main approaches used in the schools were to:
- provide time and support to allow teachers and
departments to review the messages they give out - what is
being promoted and what is being valued in the teaching and
learning of mathematics?
- create schemes of work which incorporated NRICH tasks and
embedded them in the curriculum
- change the way in which students' mathematical progress
was assessed by taking into account their strategies and
approaches
Time in department meetings was set aside to explore NRICH
activities and consider how they might be used in the
classroom in order to influence perceptions. Schools found
that it was essential for staff to work collaboratively,
preparing lessons and observing each other in order to
reflect and share good practice.
Several schools used the
Curriculum Mapping
documents published on the NRICH website to identify rich
tasks that they could link to their schemes of work. Here are
some examples of what individual schools have been doing:
- A DVD has been produced with footage of some lessons in
which rich tasks have been used. This is being shared at
department meetings to focus discussion on what the teacher
did and how this might have influenced students'
perceptions
- One week every half term is set aside where all lessons
for Years 7 and 8 are based around NRICH tasks The focus is
to encourage students to appreciate the value of mathematical
thinking and develop more independent ways of working. Issues
related to mathematical content are dealt with as they
arise.
- Teachers have been working collaboratively, identifying
and using NRICH tasks which enhance their well-established
scheme of work.
- Lesson plans are used as the starting point for
discussions about what is to be taught and how they might be
adapted to take into account the different needs of
students.
At one school, new assessment criteria have been introduced
to reflect the emphasis on skills and processes rather than
answers and algorithms. (See the revised
National Curriculum) After several iterations the
mathematics faculty is about to use seven assessment criteria
in common with the science faculty:
Experience has shown that these assessment criteria allow
students to have the full range of their contributions
recognised. This is particularly powerful for those students
who would have previously considered themselves weak when
judged by traditional assessment criteria. This means that a
student can achieve credit for several of these skills areas
even when a correct solution is not reached.
Many of the schools encouraged their students to submit
solutions to the
NRICH
problems published each month. NRICH edits and publishes a
selection of submitted solutions at the end of each month. It
is interesting to note that NRICH only publishes solutions that
contain explanations, reasoning and/or justifications. See, for
example, the solution to
American
Billions.
This example solution shows how Zac worked logically to find
the number in American Billions
.
Let A B C D E F G H I J
represent the 10 digits.
The number itself is
divisible by 10, so J must be 0.
Since the number formed by
the first 5 digits from the left is divisible by 5, E must be
5.
Since AB, ABCD, ABCDEF and
ABCDEFGH must be divisible by 2, 4, 6 and 8 respectively, they
must all be even. So B, D, F and H are even
numbers.
That leaves 1, 3, 7 and 9 for
A, C, G and I.
AB could be any of the
following:
The number formed by the
first 3 digits from the left is divisible by 3, so the digits
must add up to a number that is divisible by 3.
The possible values of ABC
must be:
The number formed by the
first 4 digits from the left is divisible by 4, so the number
formed by the last two digits of the number must also be
divisible by 4.
How well are we achieving our
aims?
One school has reported a noticeable improvement in behaviour
in Years 7 and 8 mathematics lessons since the implementation
of these strategies. This has been reflected in a drop in the
number of students who have been removed from lessons due to
unacceptable behaviour.
Students have indicated in school surveys that they prefer a
rich and varied curriculum over a more traditional diet and
have shown a greater enthusiasm for mathematics.
Jo Boaler's research evidence shows that a more varied, rich
curriculum will not be detrimental to GCSE examination results.
