标题：Examining classroom teachers' knowledge levels of geometric objects and shapes by using mind maps Sınıf öğretmenlerinin geometrik cisimler ve şekiller konusundaki bilgi düzeylerinin zihin haritaları üzerinden incelenmesi
摘要：This study aimed to investigate the level of knowledge of geometric objects and shapes as a sub-learning area of geometry learning area in primary school mathematics curriculum of classroom teachers through mind maps. The study was carried out with the case study which is one of the qualitative research methods. There are 58 class teachers who work in three primary schools. Easy sampling method was used in determining the participants. As data collection tools, mind maps designed by classroom teachers on geometric objects and shapes were used. The mind maps prepared by the teachers were examined by two researchers at the analysis stage. Based on the findings, it can be said that the teachers of class are more informed about the shapes, they have difficulties distinguishing geometric objects and shapes according to their characteristics, teachers are given less space than a square prism and sphere and some teachers confuse objects and shapes. One of the teachers was able to map the objects with the branches and the lower branches, and the three teachers could map the shapes exactly with the branches and the lower branches. Mind maps that are among the alternative measurement tools can be used as an effective tool in assessing teachers' content knowledge.
