Miriam Simone Leshin – North American Chapter of the International Group for the Psychology of Mathematics Education, 2023
Opportunities for students to share their thinking with the class--which I refer to as "work-sharing practices--require a profound shift in who is positioned with intellectual authority in mathematics classrooms. This study explores work-sharing practices in one sixth grade mathematics classroom through an interactional lens. Video analysis…

Koellner, Karen; Seago, Nanette; Jacobs, Jennifer – Teacher Educator, 2023
This research study explored teachers' self-reported uptake as well as observed instructional change after participating in a year-long professional development (PD) program focused on supporting the learning and teaching of transformations-based geometry. Analyses illuminate the degree and nature of the pedagogical shifts made by teachers who…

Sharma, Shweta – Mathematics Education Research Group of Australasia, 2023
The interactional role of language use in the mathematics classroom is explored in the last few decades. This paper adds to the knowledge base by exploring different ways of talking that children and their teacher use in a New Zealand primary geometry English-medium classroom. Bakhtin's concept of speech genres is used for an analysing transcript…

Gantt, Allison L.; Paoletti, Teo; Greenstein, Steven – North American Chapter of the International Group for the Psychology of Mathematics Education, 2022
Despite significant research exploring students' quantitative reasoning, few studies have explored the semiotic processes that mediate its development. In this report, we present a case study to show how one student constructed a semiotic chain for a quantity as he worked with a mathematical task. Importantly, we connect frameworks for…

Kobiela, Marta; Lehrer, Richard – Journal for Research in Mathematics Education, 2015
We examined the codevelopment of mathematical concepts and the mathematical practice of defining within a sixth-grade class investigating space and geometry. Drawing upon existing literature, we present a framework for describing forms of participation in defining, what we term aspects of definitional practice. Analysis of classroom interactions…

Erbas, Ayhan Kursat; Yenmez, Arzu Aydogan – Computers & Education, 2011
The purpose of this study was to investigate the effects of using a dynamic geometry environment (DGE) together with inquiry-based explorations on the sixth grade students' achievements in polygons and congruency and similarity of polygons. Two groups of sixth grade students were selected for this study: an experimental group composed of 66…
