In this epilogue we elaborate on and synthesise what we have learnt from reading this book. We start by considering what the word “apply” in Applying Critical Mathematics Education might mean. Apply connotes to put into action, but it is also related to the following ideas: to work hard at, to pay close attention to, to have relevance for and to request something. In the context of our readings we think of being relational and dedicated as a matter of enhancing situated critical awareness, addressing relevant issues as a matter of highlighting complex global and local challenges and making demands as a matter of agency and power. To us, these themes together synthesise the insights on critical mathematics education in action that the authors of this book offer; namely, propositions on how to illuminate and execute social justice and heterogenous subjectification by critically entangling local and global knowledges in contextually situated educational enactments that hold the potential to address complex challenges. We close by sharing our ideas on how the contribution of this book gives us hope for the future in these times of crises and complex challenges.
This chapter concerns how three teachers in lower secondary school include climate change in school mathematics. Data was collected over a oneyear period, where the teachers organised several teaching activities such as fieldwork, posters, contribution to an exhibition, and dialogue and debates, to facilitate students’ critical mathematics competences through working with climate change. We apply a teacher perspective and focus on the role mathematics can play in formatting the understanding of climate change. A formatting power of mathematics is identified at three levels: (1) in teachers’ metareflections, (2) when the teachers use mathematics to format students’ understanding, and (3) when teachers facilitate students’ awareness of the formatting power of mathematics. The findings suggest that a complex issue like climate change brings forth an awareness of the formatting powers of mathematics.
