Spatial Visual, a mental representation in depicting visual information, is one of important ability in solving geometry problems. This study aimed to investigate student spatial visual ability and analyze it by gender. A total of participant involved in this research was 30 junior high school students at grade seven. There were three steps in this research. First, we chose two reflection questions from spatial visual assessment by Ramful, Lowrie, and Logan. Next, we interviewed some of students by semi structure interviewed. Finally, we analyzed student spatial visual comparing to types of visualization by Hegarty and Kozhevnicov and analyzed by gender. We found that generally the students had a lack in spatial visual ability because their pictorial representation, however boys had better spatial visual ability than girls.
Visualization is a mental act representing a visual information. In solving geometry problem, we need visualization to identify and illustrate the information. This study aimed to analyse student visualization in solving the reflection problems. We studied a female high school athlete at grade eleven. There were three steps in this study. First, we designed two reflection problems. Next, we assessed and interviewed her by semi structure interviewed. Finally, we analysed student spatial visual comparing to types of visualization by Presmeg. Lot of athletes do not have time enough in learning about some topic in their class, so we have to find an appropriate approach to led her in learning activity for creating an efective learning. We found that she has two types of visualization that are pattern imagery and kinaesthetic imagery. In the future, we can design instructional tasks that are convenient for this visualizer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
