Technology is integral to modern education, supporting exploration, computation, assessment, communication, and motivation. National curriculum and teacher preparation standards, such as the Common Core State Standards for Mathematics (NGA & CCSSO, 2010) and Standards for Preparing Teachers of Mathematics (AMTE, 2017), emphasize the strategic use of technology in teaching mathematics across grade levels. At the college level, the Committee on […]

In this note, I would like to present one recurring issue that surfaced in the discussions of the GeT Transformation Geometry Working Group, and a partial resolution of that issue, contained in a suggestion by one of the reviewers of our chapter in the forthcoming GeT volume (McLeod et al., in press). More details of […]

Technological tools can be used in teacher preparation programs to develop students’ conceptual understanding of the properties of polygons and to communicate appropriate vocabulary (Kartal & Çınar, 2024). The exploration opportunities afforded using technological tools, such as Desmos, can help students develop conceptions of shapes, engage in informal deduction, and enhance their mathematical vocabulary (Herman, […]

I chose to let my students from this semester respond to these questions. Here, unfiltered, is what my students from this semester shared about the course: Our class is not directed as much by direct instruction, but rather by rich discussion. Understanding is achieved by communication, and our many different backgrounds lead to so many […]
