Infrastructure for students' writing in primary school mathematics

Abstract:

This presentation introduces my PhD project which examines how structured approaches to mathematical writing can support student learning in Danish primary school mathematics followed by a discussion regarding the project.

While existing research demonstrates the benefits of writing for conceptual understanding, its systematic integration in early mathematics education remains underexplored, particularly in Denmark. Grounded in the anthropological theory of the didactic, the project investigates mathematical writing as part of both didactical and paradidactical infrastructures shaping students’ engagement with mathematics. Drawing on Japanese practices, including the use of student notebooks and bansho, writing is positioned as integral to teaching through problem-solving.

The study combines classroom observations, lesson study interventions, and quantitative pre-, mid-, and post-tests across experimental and control groups, complemented by qualitative analyses of classroom interaction and teacher collaboration.

The project aims to develop and evaluate a sustainable infrastructure for mathematical writing, contributing to both classroom practice and international research on mathematics education.
