Yeung, W.L., & Ng, O. (2021). Developing the meaning of volume and deriving the volume of hemispheres with dynamic geometry. International Journal of Mathematical Education in Science and Technologyhttps://doi.org/10.1080/0020739X.2021.1949058

In this paper, Gordon and Prof. Ng introduce a technology-enhanced pedagogical sequence for supporting lower secondary school students’ sensemaking of the concept of volume in a non-procedural and nonformula-driven way. Specifically, they illustrate a novel approach of using dynamic geometric environment (DGE) to introduce the meaning of volume and then deriving the volume of a hemisphere with minimal algebra but simple trigonometry. This method aims to support students’ geometrical reasoning through comparing the volume of different three-dimensional shapes and analysing their cross sections two-dimensionally, thus drawing on the concept of area. They highlight the affordances of the designed DGE sketches for fostering a dynamic conception of volume.
