Title: Mathematics is both a doorway and a hurdle


1
Mathematics is both a doorway and a hurdle
  • Peter Sullivan
  • Monash University

2
Abstract
  • Successful mathematics study opens many doors.
    Mathematics also acts as a hurdle.
  • The challenge for mathematics curriculum and
    teaching is to help all students to jump the
    hurdles, so that the doors are open when they
    reach them.

3
Overview
  • Goals of the mathematics curriculum
  • Key decisions
  • Definitions
  • Assessment
  • Presentation of the curriculum

4
The curriculum needs to foster
  • development of expert mathematicians
  • expert users of mathematics in the professions
  • a workforce capable of meeting all numeracy
    requirements
  • citizens able to use the mathematics they need

5
Some of the key decisions
  • mathematics success creates opportunities and all
    should have access to those opportunities
  • inclusive for all to end of year 9 (and
    compulsory in year 10)

6
The senior secondary curriculum
  • Fundamental ( Mathematics A)
  • Rigorous, substantial, worth studying
  • Business, statistics, measurement, applied
    geometry
  • Intermediate (Mathematics B)
  • Also worth studying
  • Leading to university mathematics subjects
  • Calculus, statistical distributions, graphs
  • Advanced (Mathematics C)
  • For mathematics specialists (a little over 10)
  • Vectors, mechanics, more calculus
  • Vocational (pre vocational)

7
  • the curriculum will be clear and succinct, and
    this is about pedagogy
  • clarity is needed for interactivity
  • not about setting low expectations for teachers
  • demands for additional detail should be resisted
  • currently teachers feel they have to rush from
    one topic to the next, and this is bad for
    teaching
  • studying combined topics in more depth
  • some topics are more important than others

8
  • all students can be challenged within basic
    topics, including the advanced students
  • extension by moving to advanced topics is
    ultimately counterproductive

9
Numeracy
  • There are some who see numeracy as a separate
    subject
  • There are some who think numeracy does not exist
  • Decision is to write a numeracy curriculum within
    mathematics
  • as well as including references to numeracy
    aspects of other subjects in mathematics, and to
    numeracy in history, English and science

MATHEMATICS ASSESSMENT
  • Assessing Maths In 1970
  • A logger sells a lorry load of timber for
    1000.His cost of production is 4/5 of the
    selling price. What is his profit?
  • Assessing Maths In 1980
  • A logger sells a lorry load of timber for 1000.
    His cost of production is 4/5 of the selling
    price, or 800. What is his profit?
  • Assessing Maths In 1990
  • A logger sells a lorry load of timber for 1000.
    His cost of production is 800. Did he make a
    profit?

11
  • Assessing Maths in 2000
  • A logger sells a lorry load of timber for 1000.
    His cost of production is 800 and his profit is
    200. Underline the number 200.
  • Assessing Maths in 2008
  • A logger cuts down a beautiful forest because he
    is selfish and inconsiderate and cares nothing
    for the habitat of animals or the preservation of
    our woodlands. He does this so he can make a
    profit of 200. What do you think of this way of
    making a living?

12
The curriculum driving any assessment
  • The curriculum will outline expectations
  • But it is cheaper to assess fluency than
    reasoning
  • Assessing only one type of mathematical action
    will distort the curriculum
  • In any case, if national assessments are to
    inform us on achievement of goals, then all
    aspects must be included

13
Definitions
14
Three content strands
  • Number and algebra
  • Measurement and geometry
  • Statistics and probability
  • Features
  • 3 not 5
  • traditional terms (but not intent)
  • maximise interconnections
  • not all aspects equally important at every level

15
Expectations for proficiency
  • Understanding
  • Fluency
  • Problem solving
  • Reasoning
  • Features
  • More than working mathematically
  • All are needed

16
  • Numeracy expectations as well

Number and Algebra ( K 2)
  • Counting
  • Adfsdfsd asdfasdfasd asfdsdfsad asdfsdfas
    asdfsdfas asdfasd
  • Place Value
  • Dfsadfsd sdfsdfasd sadfsdfsd asdfsdfsd safdasdf
    adfsdfasd asdfsd fdsa
  • Addition
  • Adfsdfsd asdfsdfsd safdasdfsd asdfsdfsd asdfsdfsd
    asdfsdfs
  • Subtraction
  • Backwards counting modelling situations in which
    one part of the whole is unknown number
    strategies that are useful for subtraction
    solving subtraction word problems
  • Multiplication
  • Sdfsdfsd sfdasdfsd asdfsdfsd asdfsdfsd asdfsd
    asfsdfds asdfsdfsd asdfasd asdfsd
  • Division
  • Adfsdfs asdfsdfsad sdfasfasd asdfasdfsd sadfsdfsd
    sadfsdfasd sadfsd asfdsdfsadfasdfsd

Number and Algebra ( K 2)(elaboration)
  • Subtraction
  • Backwards counting

  • modelling situations in which one part of the
    whole is unknown
  • Asdfasdfsad sdaafasdfsad sdafasdfsdaa
    sdffasdfjasdl dsaff asdfasd sdffafsdfasd
  • number strategies that are useful for
    subtraction
  • Key facts that form the basis of strategies for
    subtraction are
  • taking away 1 and taking away 2
  • what do we need to build to 10 (6 ? 10,
    etc.)
  • doubles (the idea that if 3 3 is known then 6
    3 can be developed)
  • subtracting 10.
  • solving subtraction word problems

Subtraction - Understanding
  • Students see connections between take away, less
    than, difference between
  • Students connect with other forms of
    representations, such as empty number lines
  • Student see connections between addition and
    subtraction. They understand that if they know 7
    8 15, they also know
  • 15 7 15 8
  • 15 ? 7 15 ? 8
  • ? 7 8 ? 8 7
