<![CDATA[Mastering the topic of symmetry requires a good representational competence to smoothly understand, visualize, and manipulate the movement of three-dimensional objects. This literature study aimed to describe how concrete and virtual media can be utilized in improving students’ understanding of the topic. The study implies that the thinking process, cognitive tasks, interactions, mental models, and the completeness features displayed by the two models in identifying all symmetrical operations are the distinguishing factors of the effectiveness of the two formats in affecting students’ understanding. The study also implies that the virtual format will contribute to students’ understanding better than the concrete format does. However, the empirical study must be explored further to ensure the difference between the two formats.]]>
