Altıncı sınıf öğrencilerinin uzamsal yetenekleri ve geometrik görevlerde kullandıkları uzamsal dil ve stratejilerinin incelenmesi

The aim of the research is to investigate the sixth-grade students' spatial abilities and spatial language and strategies used in geometrical tasks. The method of the study was the mixed research methods. As a method, convergent parallel design from the mixed research methods was used. The participants of the study were selected by the convenience sampling method. Quantitative data were collected on math test results, Spatial Ability Test (SAT) and C-test. quantitative data were collected on building 3D objects with Lego implication. In data analysis, quantitative data were used with simple and partial correlation analyzes and the analysis of qualitative data was carried out with content analysis. As a result of this study, a moderate, positive, and significant relationship was found between mathematical performance, language proficiency and spatial ability scores. Not seeing the construction stages of the object, being persistent in trying, communicating effectively are the important factors that positively affect the success in the geometrical task. Again, the control strategy was found to be one of the key strategies that boosts task success. It is recommended to teachers that in the geometric tasks to be done in the classroom, observing the construction stages of the object, being persistent in trying, and establishing effective communication stand out as important factors for students' success in geometrical tasks.
