Abstract
The learning of volume measurement is closely related to the learning of geometry. Being able to visualize the shape of the object measured is necessary for students to do the volume measurement. This paper discusses students? spatial visualization development within the learning sequences on volume measurement of cubes. The research used design research methodology which consists of three phases; thought experiment, instructional experiment, and retrospective analysis. The learning activities were designed in the thought experiment phase and were underpinned by realistic mathematics education theory. The instructional experiment was conducted in a grade 8 class of a Junior High School in Karawang West Java. The retrospective analysis showed that counting unstructured group of unit cubes stimulated students to organize the cubes in a structured configuration to enable them count easily. Drawing and building 3D objects by using unit cubes has enabled students to develop their spatial visualization, that is knowing how the objects look like when seen from different angles. Finally, students were able to group the unit cubes in layers or columns and use multiplicative strategy and construct an understanding of the concept of volume of a cube.
