Abstract

Spatial visualization is a mental ability in imagining an object, manipulating objects, rotating objects along with changing elements in it, or changing objects described into different shapes. Every student has a different strategy in solving a particular mathematical problem in solving mirroring problems. The strategy used in this research is a visual and analytic strategy. The purpose of this study was to describe the visual and analytical strategies undertaken by students in completing reflection tasks based on spatial visualization mechanisms. Subjects in this study were 3 students of Junior High School from three different grades, 1 female student from grade VII, 1 male student from grade VIII, and 1 female student from grade IX. The subjects were asked to complete the reflection task and continued with the interview to obtain more in-depth data in accordance with the purposes of this study. The reflection task contains commands to reflect lines, plane, and alphabetic letters against lines in the form of horizontal, vertical, and slope symmetry lines. The results of this study indicated that the visual strategy used by the three students was visual mental folding. Although the first and second students are not consistent in using the strategy to complete all assigned tasks. The third student used the strategy consistently. The analytic strategy used by first students was to consider the distance between the object and the symmetry line, whereas second student did not consistently use the analytical strategy by considering distance. The third student maintained the analytic strategy to accomplish all the tasks assign, the analytical strategy by considering equidistance and perpendicularity.
