This issue of Hexagon: Jurnal Ilmu dan Pendidikan Matematika presents a diverse collection of studies that highlight current developments and emerging concerns in mathematics education and applied mathematical research. The articles in this edition explore a wide range of themes, including problem-solving pedagogy, students’ mathematical anxiety, numeracy skills, misconceptions in algebraic concepts, the integration of digital learning media, and the development of innovative instructional materials. Several contributions also demonstrate the practical application of mathematical modeling and statistical analysis in addressing environmental and climate-related phenomena in Indonesia.

A strong emphasis throughout this issue is placed on improving students’ engagement, critical thinking, and learning outcomes through innovative teaching strategies and technology-enhanced learning environments. The contributors examine the influence of digital media, online games, heuristic-based digital handouts, and manipulative teaching aids in supporting mathematics learning across different educational levels. In addition, this issue includes a systematic literature review discussing instructional models designed to reduce students’ mathematics anxiety, offering valuable insights for educators and researchers alike.

Contributors in this issue come from Indonesia and Nigeria, reflecting the journal’s growing international perspective and its commitment to fostering cross-cultural academic dialogue in mathematics education research. Collectively, the articles provide meaningful contributions to both theoretical and practical dimensions of mathematics education while also emphasizing the importance of contextual, inclusive, and evidence-based approaches in contemporary teaching and learning practices.
