Changing students' perceptions of mathematics and of learning mathematics
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:
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
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. See her 2005 and 2006 Journal articles that can be downloaded from http://www.sussex.ac.uk/education/profile205572.html.
