istatistiğe yönelik öz-yeterlik ölçeğinin geliştirilmesi

Bu çalışmada, öğretmen adaylarının istatistiğe yönelik öz-yeterlik algılarını ölçmek için 5li Likert tipi bir ölçek geliştirilmesi amaçlanmıştır. 214 öğretmen adayından oluşan örneklem üzerinde yapılan açımlayıcı faktör analizi sonucunda Cronbach alfa katsayısı 0,94 olan 48 maddelik İstatistiğe Yönelik Öz-Yeterlik Ölçeği geliştirilmiştir. Ölçekte bulunan 48 madde herhangi bir mantıksal problem teşkiletmeden 7 faktörde toplanmıştır. Bu faktörlersırasıylaGenel İstatistik Becerileri (Cronbachalfa = 0,93), Araştırma Becerileri (Cronbachalfa = 0,88), SPSS Becerileri (Cronbachalfa = 0,85), Zaman Yönetimive Ders Çalışma Davranışları (Cronbachalfa = 0,82), Bilgisayar Kullanma Becerileri (Cronbachalfa = 0,79), Matematik Becerileri (Cronbachalfa = 0,74) ve Ders Dinleme Becerileri (Cronbachalfa = 0,81) olarakadlandırılmıştır. Sonuç olarak, ölçeğin, öğretmen adaylarının istatistiğe yönelik öz-yeterliklerinin belirlenmesinde güvenle kullanılabileceği tespitedilmiş ve ölçekle ilgili bazı öneriler sunulmuştur.

Development of self-efficacy scale towards statistics

In this study, a five item Likert type scale to measure the teacher trainees self-efficacy perception towards statistics was aimed. As the result of the exploratory factor analysis done on the sample of 214 teacher trainees a 48 item Self-Efficacy towards Statistics Scale with a 0,94 Cronbach Alfa coefficient. The 48 items in the scale has been gathered in 7 factors without constituting a logical problem. These factors were named as General Statistics Skills (Cronbachalfa = 0,93), Research Skills (Cronbachalfa = 0,88), SPSS Skills (Cronbachalfa = 0,85), Time Management and Lecture Study Behaviours (Cronbachalfa = 0,82), Computer Usage Skills (Cronbachalfa = 0,79), Mathematics Skills (Cronbachalfa = 0,74) and Lecture Listening Skills (Cronbachalfa = 0,81). As a result, the scale has been identified as reliable for usage to evaluate the teacher trainees self-efficacy towards statistics and some suggestions were offered.
