New tools, new learners … new numeracies? Merrilyn Goos The University of Queensland
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?
What is numeracy? • Numeracy involves … • A numerate person can … • A numerate person knows … • A numerate person is …
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
Early definitions of numeracy • The mirror image of literacy, but involving quantitative thinking. Crowther Report, 1959 (UK)
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 individual’s current and future private life, occupational life, social life with peers and relatives, and life as a constructive, concerned and reflective citizen. PISA, 2001
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
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)

Workplace numeracy: Pilots calculating crosswind crosswind 45º Wind velocity20 knots runway
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.”
Workplace numeracy: Pilots calculating crosswind Watch face estimate 0.75

Claim Technology robs learners of the ability to think. Counter claim Technology can change and enhance the way humans solve problems. Exploiting tools for numeracy
I often don’t know if I’ve used it correctly and as a consequence I can’t be sure if my answer is correct or not. Technology as Master
I regularly use technology for familiar tasks purely as a time saver and to verify and check my answers. Technology as Servant
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 don’t know what I’d do without him.”
Technology as Extension of Self “My calculator is practically a part of myself. It’s like my third brain. I use it whenever it can help me do anything faster.”
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 wouldn’t 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 • Don’t want to work • Permanently unable to work
Who counts as “unemployed”? 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 wouldn’t 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 • Don’t want to work • Permanently unable to work marginally attached no marginal attachment
