Targeted Teaching Works!
75% of the fastest growing
occupations require STEM 1
44% or 5.1 million jobs at risk from digital disruption 1
The average performance of Year 8 students in
mathematics has not changed since TIMSS 1995 2
Australia’s mean mathematical literacy performance declined significantly between PISA 2003 and PISA 2012 and males
significantly outperformed females 4

Shifting 1% of workforce into
STEM roles would add $57.4
billion to GDP over 20 years 1
The number of students taking
intermediate and advanced maths at
secondary school has fallen by 34% over the
last 18 years 3

Ø Success in school mathematics is a strong predictor of STEM engagement (Wai et al, 2009; Lowrie, 2017)
A situation analysis:
Ø Proportion of students undertaking Specialist Maths is declining (AIG, 2015)
Ø There is a 7-8 year range in mathematics achievement in each year level 5 to 9 (Siemon, 2006, 2016)
Ø Students are opting out of STEM courses in the senior years (PWC, 2015)
Why are Australian students opting out of STEM?Some possibilities:• Unlike many other countries (e.g., Finland, the USA and China),
mathematics and science are not mandated studies at Year12 (Wilson, The Conversation, 2015)
• Spoilt for choice – the number and range of subject offerings in the final years of schooling (e.g., over 100 subjects in VCE)
• Intermediate and Advanced level mathematics not necessarily required for further STEM study (Academy of Science, Decadal Plan, 2016)
• STEM paradox – the underemployment of STEM graduates, particularly in life sciences, chemistry and physics (Productivity Commission Report, June 2016)
• Perceived risk to ATAR scores – the ‘opportunity costs’ associated with choosing STEM subjects (Connolly, CIO, 2016)

• Up to 55% of Year 8 students do not have access to multiplicative thinking and, as a result, experience considerable difficulty with fractions, decimals, ratio, percent and all forms of proportional reasoning (MYNRP, 2001; SNMY 2006; RMF, 2013)
• Many Year 4 to 9 students are unable to apply what they know to solve unfamiliar situations, explain their thinking or communicate mathematically (MYNRP, 2001; SNMY, 2006; RMF, 2013)
• Spatial ability plays a critical role in developing STEM expertise (Wai, Lubinski & Benbow, 2009; Lowrie, 2017)
• A significant proportion of Year 7 to 10 students experience difficulty with tasks requiring spatial, algebraic or statistical reasoning (RMFII project 2014 -)
Symptoms not causes?
Good news is that targeted teaching works!
Targeted teaching is a form of differentiated instruction that is specifically concerned with student’s learning needs in relation to a small number of really ‘big ideas’ in number without which students’ progress in school mathematics will be seriously impacted (Siemon, 2006).

The ‘BIG IDEAS’ in Number Generalising
© Dianne Siemon
Students in an identified sub-sample of ‘at-risk’ students within the SNMY Project demonstrated major shifts in achievement against the Learning and Assessment Framework for Multiplicative Thinking (LAF) as a result of an 18 week, 2 sessions per week teaching program (Breed, 2011)*
* A copy of the Intervention Teaching Program for At Risk Students is included in the SNMY Project Findings, Materials and Resources available on the DET and TasEd websites.
Participants: 9 Year 6 students identified at Level 1 of the Framework in May 2004
Results: All students achieved at Level 4 or 5 of the Framework in November 2005
For example,
Targeted teaching requires:
• sufficient time with students to develop trust and supportive relationships; and
• flexibility to spend time with the students who need it most.
• access to assessment techniques that expose student’s thinking;
• a grounded knowledge of learning trajectories (key steps in the development of big ideas and how to scaffold these);
• an expanded repertoire of teaching approaches which accommodate and nurture discourse, help uncover and explore student’s ideas in constructive ways, and ensure all students can participate in and contribute to the enterprise;

Aim: To build a sustainable, evidence-based learning and teaching resource to support the development of mathematical reasoning in Years 7 to 10Approach: • Develop Hypothetical Learning Trajectories for algebraic,
spatial and statistical reasoning from previous research • Develop, trial and validate rich assessment tasks for
Mathematical Reasoning (MR)• Use results to identify big ideas, Draft Learning
Progressions and teaching advice• Trial and evaluate MR Assessment Forms, teaching
advice and activities; monitor student progress.

Why algebraic, geometric and statistical reasoning in Years 7 to 10
16
• Although 85% of the Year 8 mathematics curriculum requires some form of multiplicative thinking (Siemon, 2013), this is not reflected in curriculum descriptors or textbooks
• Curriculum sequences tend to be based on historical precedent rather than research (e.g., linear equations have always been taught in Year 7, integers in Year 8)
• The large range in student achievement at this level tends to promote over-scaffolding and the atomisationof the curriculum into discrete ‘topics’ and skill sets, leaving ‘no room’ for complex problem solving, inquiry, extended discussion or mathematical reasoning
Need for evidence at scale
i. core knowledge needed to recognise, interpret, represent and analysealgebraic, spatial, statistical and probabilistic situations and the relationships/connections between them;
ii. an ability to apply that knowledge in unfamiliar situations to solve problems, generate and test conjectures, make and defend generalisations; and
iii. a capacity to communicate reasoning and solution strategies in multiple ways (i.e. diagramatically, symbolically, orally and in writing).
What is needed…

Assessing mathematical reasoning (MR)• Tasks developed on the basis of
the HLTs and trialed in RMFII Schools (3254 student records)
• Multiple Forms comprising 5 to 6 tasks prepared and trialed as Standard Forms (strand-specific) or Mixed Forms (two strands)
• Forms prepared as booklets and administered over 2 to 3 sessions in Trial and RMFII schools
• Scoring rubrics used to assess student MR
• Codes used to enter student data and track progress
• Tasks and rubrics redesigned as needed by Research Team

Analysis - Developing the draft learning progressions (DLPs):Assessment tasks were separately coded to track use across Forms (e.g., ATILP3 refers to the third item in Algebra Tiles)
The resulting data were analysed using the Rasch partial credit model (Masters, 1982) using Winsteps 3.92.0 (Linacre, 2016). This allows both student performance and item difficulties to be measured using the same unit (logit), and placed on an interval scale (Bond & Fox, 2015).

Should you choose Box A, Box B or doesn’t it matter?Please explain your answer using as much mathematics as you can
SCORE DESCRIPTION ZONE
0 No response or irrelevant response
1 Incorrect (A or B) or Correct (it doesn’t matter) with little/no explanation or general statement involving chance (e.g., could be anything, just luck, 50/50 pick)
2. Beginning to consider aggregated information but without an appreciation of statistical value e.g., identifies an incorrect association between two variables; describes what a graph is about without any interpretation etc
2 Correct or Incorrect, explanation relies on quantities alone suggesting additive thinking (e.g., it idoesn’t matter both have more red, A because it has only 2 more reds and B has 20 more reds or B because it has more blues)
4. Links statistical ideas such as variation but inconsistently, sometimes linking inappropriately in complex contexts such as two-way tables
3 Correct (it doesn’t matter) with an explanation that suggests multiplicative thinking (e.g., they both have a 40% chance
5. Makes informal group comparisons (not just single values) and summarises data with simple numerical statements but no proportional reasoning

Mathematics is central to STEM
It is the only subject whose study consistently enhances performance across all fields of science. It forms the basis of most scientific and industrial research and development. As an enabling discipline, mathematics, has been, and will continue to be at the heart of our search for ways to solve, manage, mitigate or adapt to some of the great challenges that confront us as a nation and as part of humankind.
