Charting Ways Ahead: A Personal Perspective
Kaye StaceyUniversity of Melbourne
Maths, Science and Environmental Sciences are mutually supportive but separate disciplines
Differences in– Role in education of a citizen– Values which they impart– Links to natural and/or social worlds– Time scale of change in subject matter– Role of a central core of fundamental knowledge– Nature of reasoning and evidence– Degree of abstraction– Ways in which they can be best learned
Good pedagogy for maths does not just copy other subjects
• Maths can be important in cross-discipline studies, but usually as “servant” (recent examples from ASMS Adelaide, Singapore )
• Maths can’t be adequately taught just as another “literacy”
Good maths teaching attends to:
conceptual understanding
reasoning & explanation
productive dispositions
applications & real world links
procedural fluency
strategic competence
What does good maths look like in school?
Have we got it yet?
TIMSS Video Study “Teaching Mathematics in Seven Countries”• Australia, Czech Republic, Hong Kong, Japan,
Netherlands, Switzerland, United States• Data collection 1999/2000 in YEAR 8• One randomly selected lesson in each of 87
randomly selected schools in Australia• Extremely detailed and careful
categorisation of lesson features and procedures
• Backdrop: Australia doing reasonably well in international comparisons of achievement
TIMSS 1999 video study

Overall findings
• Australian schools have good relationships and classroom environment
• Countries have reasonably distinctive styles of lessons – Japan is different
• Some expectations not upheld e.g. Australia only average in use of real world contexts in maths
Shallow Teaching Syndrome: Procedures without Reasons
1. Excessive Repetition• 76% of problems exact repeats• 65% of time repeating demonstrated
procedures
2. Low complexity of problems• 77% of problems low complexity
3. Absence of mathematical reasoningAt 7-country “worst” on these
measures

Absence of mathematical reasoning
• No Australian lessons showed deductive reasoning (loosely defined)
• 15% of problems in “making connections” category
• 2% of public problem solutions in “making connections” category

We have a long way to go
Question Can we get there?
Advantages
Current group of new teachers
External climate conducive to working on teaching
Tomorrow’s teachers in “science methods”
• University of Melbourne DipEd and BTeach
• Enrolment trends – not official numbers
• Survey of 90 students in 2002 (repeated 2003) about background and aspirations

Most common reasons for choosing teaching
1. Enjoy teaching / always wanted to2. Need a job 3. Want secure job with
opportunities for advancement4. Want satisfying work with positive
social contributionVery good for education but what
does it say about science?

Consequences
• Substantial experience of life, work and research
• Challenge to schools to keep them!
• Science teachers trained as scientists; maths teachers NOT trained as mathematicians (consequences for some aspects of curriculum)
RITEMaths Project
• Universities of Melbourne & Ballarat• Kaye Stacey, Gloria Stillman, Robyn
Pierce and colleagues• Funded by Australian Research
Council, six secondary schools and Texas Instruments
Real world problems and IT Enhancing Mathematics
RITEMaths Project
Better outcomes and more complete understanding of maths
Stronger engagement
Lessons with more cognitive demand
Real world problems used more substantially
Enabled by IT
Maths from Images and Videos
Image Analysis Software
• GridPic– created for Luther College,
Melbourne– especially for Years 9 – 11– part of work of RITEMaths Project– Start GridPic here

Vision
Increasing engagement in lessons by using real world situations (and IT)
Harnessing teachers’ and schools’ desire to increase IT use
IT naturally mathematises the worldAdditionally work on
Why use IT?
• IT naturally mathematises the world• Students like it• Teachers and schools want to use it• Opportunities to extend what we
can do• (And don’t forget the negatives!)
Why use real world problems
• Aim to capture students’ interests• Important that students learn
about how maths is used• Research exploring use of
situations to ground concept development (e.g. in algebra)
• Research on how to use real world situations deeply to promote reasoning etc.
