Conference Theme: Mathematics for a Connected World: Integration, Challenges, and Possibilities MEI 10 was a significant milestone for the mathematics education research community in Ireland. The conference theme: Mathematics for a Connected World: Integration, Challenges, and Possibilities, offered the opportunity to reflect on progress, on ‘sticky problems’ and possible ways forward in a changing, and complex, world. It challenged researchers to consider how the ideas of integration and connections play out in relation to mathematics and its teaching. Specifically, the milestone of MEI10 offered the opportunity to reflect on progress and envision the future thorugh consideration of the following interconnected issues: Disciplinary and interdisciplinary teaching and learning; the role of mathematics across subjects and real-world contexts (Maass et al., 2019) The role of mathematics education as a response to contemporary challenges, including ecological (Barwell et al., 2022) and societal issues (Bartell, 2018) Evolving educational and policy landscapes (NCCA, 2024)
