2
Some questions
  • What is meant by numeracy in the 21st century?
  • What repertoire of numeracy practices do young
    people demonstrate in life outside school?
  • How can we develop numeracy practices at school?

3
What is numeracy?
  • Numeracy involves
  • A numerate person can
  • A numerate person knows
  • A numerate person is

4
What is numeracy?
  • Some lay views of numeracy
  • numbers (doing sums, arithmetic)
  • the basic maths people need in order to survive
    in the real world
  • the name for primary school maths
  • the name for the vegie maths subject in secondary
    school

5
Early definitions of numeracy
  • The mirror image of literacy, but involving
    quantitative thinking.
  • Crowther Report, 1959 (UK)

6
Early definitions of numeracy
  • Possessing an at homeness with numbers and an
    ability to use mathematical skills to cope
    confidently with the practical demands of
    everyday life, together with understanding of
    information presented in mathematical terms.
  • Cockcroft Report, 1982 (UK)

Mathematical literacy
  • Mathematical literacy is the capacity to
    identify, understand and engage in mathematics,
    and to make well-founded judgments about the role
    that mathematics plays in an individuals current
    and future private life, occupational life,
    social life with peers and relatives, and life as
    a constructive, concerned and reflective citizen.
  • PISA, 2001

9
Distinguishing numeracy from mathematics
  • Mathematics climbs the ladder of abstraction to
    see, from sufficient height, common patterns in
    seemingly different things. Abstraction is what
    gives mathematics its power it is what enables
    methods derived from one context to be applied in
    others. But abstraction is not the focus of
    numeracy. Instead, numeracy clings to specifics,
    marshalling all relevant aspects of setting and
    context to reach conclusions.
  • Steen, 2001

10
20th century numeracy
  • To be numerate is to use mathematics effectively
    to meet the general demands of life at home, in
    paid work, and for participation in community and
    civic life.
  • Numeracy, A Priority for All
  • (DETYA, 2000)

Calculating crosswind using a watch face
  • Angle is 45º 45 minutes is three quarters
    around the watch face so the crosswind component
    is about three quarters of the 20 knot wind
    speed, namely 15 knots.

25
Numeracy for critical citizenship
Are you worried about the rise in crime among
teenagers?
Yes
Do you think there is a lack of discipline and
vigorous training in our Comprehensive Schools?
Yes
26
Numeracy for critical citizenship
Do you think young people welcome some structure
and leadership in their lives?
Yes
Do they respond to a challenge?
Yes
27
Numeracy for critical citizenship
Might you be in favour of re-introducing National
Service?
Yes!

Numeracy for critical citizenship
Are you worried about the danger of war?
Yes
Are you unhappy with the growth of armaments?
Yes
29
Numeracy for critical citizenship
Do you think theres a danger in giving young
people guns and teaching them how to kill?
Yes
Do you think its wrong to force young people to
take up arms against their will?
Yes

Exploiting tools for numeracy
  • Claim
  • Technology robs learners of the ability to
    think.
  • Counter claim
  • Technology can change and enhance the way humans
    solve problems.

39
Technology as Master
40
Technology as Servant
41
Technology as Partner
  • My calculator has become my best friend. His
    name is Wilbur. Me and Wilbur go on fantastical
    adventures together through Maths land. I dont
    know what Id do without him.

42
Technology as Extension of Self
  • My calculator is practically a part of myself.
    Its like my third brain. I use it whenever it
    can help me do anything faster.

43
Calculators in Primary Mathematics project
  • 6 Melbourne schools 1000 children 80 teachers
  • Prep-Year 4
  • Children given their own arithmetic calculators
  • Teachers not provided with activities or program

46
Exploiting contexts for numeracy
  • Connections to real life
  • Connections to other school subjects

Who counts as unemployed?
  • Want to work, actively looking for work,
    available to start work immediately
  • Want to work, actively looking for work,
    available to start work within 4 weeks
  • Want to work, actively looking for work, not
    available to start work within 4 weeks
  • Want to work, not actively looking because they
    believe they wouldnt be able to find a job, but
    would be able to start within 4 weeks
  • Want to work but not actively looking and not
    available to start within 4 weeks
  • Dont want to work
  • Permanently unable to work

Who counts as unemployed?
  • How would the unemployment rate change if we
    redefined the labour force to include people
    who are designated as marginally attached to the
    labour force?

Barbie and beauty
  • Is Barbie a realistic representation of human
    proportions?
  • What would Barbie look like if scaled up to human
    height?

55
Numeracy messages
  • Numeracy has no content of its own - it inherits
    its content from the context.
  • Workers do use mathematics but not necessarily
    the standard, visible mathematics taught at
    school.
  • Technology is ubiquitous in the world outside
    school and should be exploited intelligently to
    develop students numeracy practices.
