Title: Putting research into practice


1
Putting research into practice
  • Anne Watson
  • Oxfordshire
  • Feb 2008

2
Some key issues from research
  • What mathematics?
  • International comparisons who does well in what
    tests?
  • Its the maths!
  • What is difficult about maths?
  • Collaboration of a particular kind

3
Your first task
6 cm
3 cm
4
What mathematics?
  • Five strands of mathematical competence
  • conceptual understanding
  • procedural fluency and mathematical repertoire
  • strategic competence
  • adaptive reasoning
  • productive disposition
  • (Kilpatrick et al. Adding it up)

5
What mathematics?
  • Mathematical habits of mind
  • (Cuoco, Goldenberg, Mark)
  • What good mathematics students do
  • (Krutetskii)

6
Your second task
  • What is the height of each of the 11 steps?

250 cm
495 cm
7
International comparisons what tests?
  • TIMSS 2003
  • Questions based on reproducing knowledge and
    techniques
  • PISA/OECD 2006
  • Questions revealing mathematical literacy
  • thinking and reasoning
  • argumentation
  • communication
  • modelling
  • problem posing and solving
  • representation
  • using symbolic, formal and technical language
  • use of aids and tools

8
International comparisons who does well in what
tests?
  • Korea, Hong Kong, Belgium, Sweden, Australia,
    Chinese Taipei, Netherlands, Estonia do better
    than UK in both
  • Do better than us in TIMSS and worse in PISA US,
    Lithuania, Slovak Republic, Russia, Latvia
  • Do better than us in PISA but worse in TIMSS New
    Zealand
  • Do better than us in PISA and did not take part
    in TIMSS Finland, Azerbaijan, Canada,
    Macao-China, Liechtenstein, Switzerland, Denmark,
    Ireland, Iceland, Czech Republic

9
Its the maths
  • What they did not have in common
  • Lesson format
  • Task types
  • Calculator and ICT use
  • Amount of whole class interaction
  • Ways of arranging students
  • Number of examples
  • Techniques or problem-solving

10
Its the maths
  • Comparing 6 high-achieving nations - what they
    had in common
  • Teaching harder maths
  • Mathematical coherence in lessons
  • Mathematical rationale explicit
  • Helping students do complex tasks rather than
    simplifying the tasks

11
Your third task
  • Write down as many things as you can about the
    number 143
  • Write down as many things as you can about the
    number 1.43

12
So what is so difficult about maths?
  • Inherent difficulties
  • Notations
  • Changes of meaning
  • Limitations of images

13
So what is so difficult about maths?
  • Concept images are individually constructed

14
So what is so difficult about maths?
  • Some images are better than others

15
Importance of tasks
  • Decay of tasks
  • Freudenthal Its not the way that you do it
    its whether you get stuck in the way that you do
    it
  • Task activity what learners actually get to
    do

16
Your fourth task
  • You have a collection of brightly coloured
    cardboard discs, a space in which to move 30
    students easily, some rope, some white carpet
    tape, some compasses, some rulers, some pencils
    outline a first lesson about loci

17
Loci
  • What do you say? What do you indicate? What
    arm-waving do you do? What do you mark?
  • What concept image of loci do your students get?
  • Did you start by sharing your ideas of what locus
    is?

18
Collaboration
  • Currently collaboration is good - networking
    encouraged
  • Need to discuss teaching in detail
  • Differences in images and meaning make a
    difference to learning

19
Awkward questions
  • When does collaboration gloss over the detail?
  • When does teachers mathematical subject
    knowledge get glossed over?

20
Summary
  • Teaching harder maths
  • Mathematical coherence in lessons
  • Mathematical rationale explicit
  • Helping students do complex tasks rather than
    simplifying the tasks
  • Good choice of examples
  • Collaboration which focuses on mathematical
    details
