Building Blocks of Modern Mathematics Learning

PISA Mathematics Framework

By teaching maths through context-rich problems, learners are better able to see the relevance of their mathematical knowledge. PISA puts forth four different contexts in which mathematics should be presented to pupils to highlight the variety of its applications:

❑ Personal
❑ Occupational
❑ Societal
❑ Scientific

Being able to apply 21st century skills in a real-life setting is true ‘mathematical literacy’, defined by PISA as ‘an individual’s capacity to reason mathematically and to formulate, employ and interpret mathematics to solve problems in a variety of real-world contexts.’

Quantification plays a huge role in both mathematics and many everyday situations. By considering quantity, learners are better able to grasp magnitude and scale, using this to reason and develop number sense.

Although quantity can help with interpretation, large data sets often require the implementation of tools. PISA acknowledges the role of ‘computer simulations’ to assist in the data-handling and problem-solving process, leaving space for student creativity.

This proposed focal point develops flexible thinking, harnessing creativity by encouraging students to explore and consider ever-changing and evolving interactions in the world.

In life, there are variable degrees of ebbs and flows. Growth and decay can’t always be predicted in a linear, or even exponential, fashion as an algorithmic approach suggests. Change and relationships consider traditional skills but apply them in a way that showcases their real-life complexities.

Whilst modelling solutions and interpreting data can be useful, there are many scenarios in life which are more complex and unpredictable than the traditional teachings of probability and statistics.

Mathematical conclusions are not always definitive. PISA highlights ‘conditional decision making’ as a key topic within this focal point, to ensure learners recognise variance and how conclusions are drawn from assumptions and relationships, which, when altered themselves, can change outcomes.

Formulaic ways of looking at space and shape fail to acknowledge that patterns and symmetry are not always seen in real-life contexts. Current curriculums tend to consider shapes as fixed, whereas in reality dimensions and positions are subject to change.

PISA places additional focus on ‘geometric approximation’ to instil in learners that flexibility of thought is required to find approaches to complex real-life space and shape problems. It’s both a tangible and intangible concept that requires creativity and strong visualisation skills to apply learnt knowledge in a broader context.

Traditionally, mathematics has been viewed linearly. However, the ‘number sense’ concept promotes that even basic calculations can be approached in many different ways. Learners should be encouraged to be creative, flexible and inquisitive — skills that were not developed with the old method of algorithmic thinking or reasoning.

PISA’s list of mathematical modern-day skills:
✓ critical thinking
✓ creativity
✓ research and inquiry
✓ self-direction, initiative and persistence
✓ information use
✓ systems thinking
✓ communication
✓ reflection
