Abstract
The paper is focused on pre-service mathematics teachers' solution of a task related to the axial symmetry of 1D- and 2D-figures. The task was part of several tests in our long-term research of the spatial ability and conceptual knowledge of pre-service mathematics teachers in the field of school geometry, which follows on from our previous research.
We were primarily interested in whether and how the misconceptions, that students have formed at lower levels of education, can be influenced by university lessons. We have found that pre-service teachers do not have problems with prototypical shapes, but certain misconceptions regarding unusual tasks persist, although they are partially eliminated by university studies.
