Decentring research on mathematics teacher education: Why does it matter?

The current Special Issue, titled "Decentring research on mathematics teacher education", adds to the journey that the research community of mathematics teacher education is doing towards the growing and strengthening of a more equitable, diverse and inclusive domain. There is not a punctual occasion in which this journey started. Several initiatives over a period of decades have been and are contributing to the process of becoming a research domain that also represents the contexts, cultures and voices of historically marginalised world regions (Scheiner et al., 2024) and groups in society (Abtahi & Planas, 2024), by examining ways of addressing their needs, concerns and challenges.
