Aptitude
School learning has many facets
Students’ characteristics
Directly shaped by teachers/ schools / systems

Opportunity to learn refers to the content
taught in the classroom and the time a student spends learning this
content
7
Many students have never heard of basic mathematics concepts

WHY ACCESS TO MATHEMATICS MATTERS
AND HOW IT CAN BE MEASURED
10
Applied mathematics Working out from a <train
timetable> how long it would take to get from one place to another.
Calculating how much more expensive a computer would be after
adding tax.Calculating how many square
metres of tiles you need to cover a floor.
Understanding scientific tables presented in an article.
Finding the actual distance between two places on a map with a 1:10,000
scale.
Calculating the power consumption of an electronic appliance per week.
Pure mathematics
Solving an equation like: 6x2 + 5 = 29
Solving an equation like 2(x+3) = (x + 3)(x - 3)
Solving an equation like: 3x+5=17

• Countries where students have higher familiarity with geometry and algebra perform better in all tasks and relatively better on tasks requiring geometry and algebra
• Performance on tasks with a focus on geometry deteriorated between 2003 and 2012
Structure of curriculum
• Increasing instruction time in mathematics beyond 6 hours a week has no clear relationship with performance. The relationship differs substantially across countries, and within countries according to the quality of the disciplinary climate in the classroom
• Exposure to pure mathematics tasks (equations) is strongly related to performance
• Exposure to and familiarity with mathematics concepts may not be sufficient for solving problems that require the ability to think and reason mathematically
Amount/type of
mathematics tasks and performanc
e
• Almost 20% of the performance gap of disadvantaged students is explained by their lower familiarity with mathematics concepts.
• Disadvantaged students lag behind other students particularly in those complex tasks requiring modelling skills and the use of symbolic language.

• Exposure to more complex mathematics concepts is associated with• lower self-concept and higher anxiety among low-
performing students, and with• higher self-concept/lower anxiety among high-
performing students
Opportunity to learn
and attitudes towards
mathematics
• Peers: Having hard-working friends can increase mathematics self-concept, but students can develop lower beliefs in their own ability when they compare themselves to higher-achieving peers
• Parents may transfer their feelings about mathematics to their children, even high-performing ones
• Teachers’ practices can have a different relationship with students self-concept and anxiety depending on students’ familiarity with mathematics

Sweden and Finland reformed their education

outcomes later on. Also Germany and Poland
