İlköğretim 5. Sınıf Öğrencileri Geometrik Şekillerdeki Simetri Doğrularını Cabri Geometri Yazılımı Yardımıyla Nasıl Belirliyorlar?

Bu araştırmada, ilköğretim beşinci sınıf öğrencilerinin Cabri Geometri yazılımı ele çeşitli geometrik şekillerdeki simetri doğrusu / doğrularını nasıl belirlediklerinin devamını amaçlamış. Araştırma eylemi araştırmanın yanında desenlenmiş ve altı ilköğretim beşinci sınıf öğrencilerinin katılımı ile gerçekleştirilmiştir. Veriler için video kayıtları, klinik görüşmeler, çalışma ve günlükler açısından toplanmıştır. Cabri Geometri içeren belirlerken, doğru düzlemsel şekillerdeki simetri doğrularını, simetri doğrusunun yani oluşturduğu parçaların eşliğine, oluşturmaya, doğru katlandığında parçaların çakışmasına ve verilen şekillerin kenar uzunluklarının/açı ölçümlerinin eşit olmasına odaklandıkları görülmüştür.

How do the fifth grade primary school students determine the line of symmetry in various geometrical shapes using Cabri Geometry software?

The aim of this study was to investigate the way that the fifth grade students define line of symmetry in various geometrical shapes using Cabri Geometry software. The study was designed as an action research and six fifth grade primary school students participated. The data was collected through video recordings of weekly teaching periods, clinical interviews, worksheets and diaries. Consequently, it was observed that when the shapes were fold visually by students along the line and the equality of the edge length/ angle measurements of the given shapes by using Cabri software the students mostly focused on the equality of pieces shaped by lines of symmetry, its reflection, the collision of the pieces.
