Bu çalışmanın amacı ortaokul düzeyinde öğrenim görmekte olan öğrencilerin geometriye yönelik tutumlarını belirlemek için bir ölçeğin geliştirilmesidir. Bu amaçla çalışma tarama modeline göre tasarlanmıştır. Çalışma grubunun belirlenmesinde uygun/kazara örnekleme yöntemi ele alınmış ve çalışma İzmir ilindeki bir devlet ortaokulunda gerçekleştirilmiştir. Çalışmaya bu ortaokulda öğrenim görmekte olan 640 ortaokul öğrencisi katılmıştır. Ölçeğin faktör yapısının belirlenmesi için açımlayıcı faktör analizi ve ortaya konan yapının sınanması amacıyla doğrulayıcı faktör analizi yapılmıştır. Madde analizleri gerçekleştirilerek, iç tutarlılığın belirlenmesi için de Cronbach alfa güvenirlik analizleri yapılmıştır. Açımlayıcı faktör analizi sonucunda ölçeğin üç faktörden meydana geldiği belirlenmiştir. Bu faktörler; Olumlu tutumlar, Olumsuz tutumlar ve Teknolojidir. Doğrulayıcı faktör analizi sonuçlarına göre ölçeğin mükemmel derecede uyum sergilediği belirlenmiştir. Madde analizleri sonucunda ise ölçekte yer alan maddelerin yeterince ayırt edici, yüksek geçerliğe sahip ve aynı yapıyı ölçen maddeler oldukları ortaya konmuştur. Güvenirlik analizleri ile ölçek ve ölçek alt faktörlerinin yeterince güvenilir oldukları tespit edilmiştir. Sonuçta geliştirilen ölçeğin ortaokul öğrencilerinin geometriye yönelik tutumlarının belirlenmesinde kullanılabilecek geçerli ve güvenilir bir araç olduğu ortaya çıkmıştır.
The aim of this study was to develop a scale to determine middle school students' attitudes towards geometry. The study was designed as a screening model. The study group was designed according to convenience sampling. Therefore, the study was conducted in a middle school which is located in Izmir. 640 middle school students who were studying at this school participated in this study. In order to determine a factor structure of the scale, exploratory factor analysis was used and to verify this structure confirmatory factor analysis was used. Item analyses were performed. Cronbach alpha was also calculated to determine internal consistency reliability. It was found that the scale has three sub-factors according to exploratory factor analysis. These sub-factors are as follows: Positive attitudes, Negative attitudes, and Technology. It was seen that the scale showed perfect agreement according to confirmatory factor analysis. As a result of the item analyses, it was revealed that the items in the scale were sufficiently distinguishable, had high validity, and measured the same structure with the scale. The reliability analyses showed that the scale and the scale's sub-factors were reliable. As a result, it was found that the scale that could be used in order to determine middle school students’ attitudes towards geometry was a valid and reliable instrument.
