Plenary Panels

Plenary panels facilitate shared understanding between different communities of mathematics educators by providing a forum to debate a contested area of work in the field. ICME-15 will see panellists address two major challenges currently facing mathematics educators across the globe:

Plenary Panel 1: Mathematics education effectively responds to humanity's problems.

This panel will take the form of an Oxford debate. Panellists will explore the interaction between mathematics education and issues of enormous importance to society, such as climate change, pandemics, international conflicts, and ongoing inequities. What role, if any, should mathematics education play beyond ensuring that countries have mathematical literate citizens? What are the ethical and practical challenges?

Plenary Panel 2: What counts as evidence in mathematics education?

Policy makers, teachers, and other stakeholders require evidence in support of calls for change in mathematics teaching and learning. This panel will explore what counts as evidence in mathematics education, including forms of evidence, and the implications for research agendas and methodologies that arise from the need for evidence. How can mathematics education researchers influence the understanding of what constitutes quality evidence? How can we ensure that research evidence is heard, understood, and recognised?
