Abstract
The article presents the results of testing the spatial abilities of pre-service teachers, with the aim of identifying geometric task difficulty, and providing them with adequate training in geometry classes. Pre-service mathematics secondary school teachers were given an online test with geometric tasks in the plane and in the three-dimensional space.
Our aim was to measure their performance in spatial orientation and spatial visualization geometric tasks. The primary research questions were in which types of geometric tasks students were more successful and what their opinion was regarding the difficulty of the selected tasks.
We found out that students' success rate in spatial orientation and spatial visualization tasks was similar. Furthermore, students were more successful in the spatial geometric tasks than in the planar tasks.
