Potentials for Spatial Geometry Curriculum Development with Three-Dimensional Dynamic Geometry Software in Lower Secondary Mathematics.

The purpose of this research is to clarify the potentials of spatial geometry curriculum development in lower secondary schools through utilizing three-dimensional dynamic geometry software. By applying the impact of this software which is epistemological, five potentials are identified as followed: empowering the learning activities in spatial geometry, empowering activities wherein space figures are logically explored, expanding the learning content of spatial geometry, strengthening the connection of content in different units, strengthening the relationships between mathematics and real world.
