This document announces a new ICMI Study being conducted by the International Commission on Mathematical Instruction (ICMI). The Study, the 26th led by ICMI, addresses the advancements and current challenges in the teaching and learning of geometry, with particular attention to how the landscape has changed in the past three decades since the ICMI Study 9 on “Perspectives on the Teaching of Geometry for the 21st Century” (Mammana & Villani, 1998). Fundamentally, the International Program Committee (IPC) considers that geometry is positioned as a powerful pathway to support the understanding of complex ideas within school mathematics and beyond. In fact, we boldly suggest that geometry education is at its most exciting and quickly advancing period of the past 100 years. This ICMI Study examines the nature and role of geometry in mathematics education and related fields with an eye to the increasing depth and range of geometry education research, knowledge, pedagogies, and approaches on an international scale.
