PRIMARY STUDENTS' SPATIAL VISUALIZATION AND SPATIAL ORIENTATION: AN EVIDENCE BASE FOR INSTRUCTION

This paper reports on the performance of 58 11- to 12-year-olds on a spatial visualization task and a spatial orientation task. The students completed these tasks and explained their thinking during individual interviews. The interview data were analysed to inform pedagogical content knowledge for spatial activities. The study revealed that "matching" or "matching and eliminating" were the typical strategies that students employed on these spatial tasks. However, errors in making associations between parts of the same or different shapes were noted. Students also experienced general difficulties with visual memory and language use to explain their thinking. The students' specific difficulties in spatial visualization related to obscured spatial elements, the perspective used, and the placement and orientation of shapes.
