Bilgisayar Programlama Öz-Yeterlik Ölçeğinin Türkçe Formunun Geçerlik ve Güvenirlik Çalışması

Öz

Bu araştırmanın amacı, Tsai, Wang ve Hsu (2019) tarafından geliştirilen Bilgisayar Programlama Öz-yeterlik Ölçeğinin Türkçe diline uyarlanması, geçerlik ve güvenirlik sonuçlarının ortaya konulmasıdır. Araştırma, 297 lise ve üniversite öğrencisi ile yürütülmüştür. Orijinal ölçek 16 madde ve beş faktörden (Mantıksal Düşünme, İşbirliği, Algoritma, Kontrol ve Hata Ayıklama) oluşmaktadır. Ölçeğin yapı geçerliğinin test edilmesi için birinci ve ikinci düzey doğrulayıcı faktör analizleri yapılmıştır. Ayrıca yakınsak ve ıraksak geçerlik çalışmaları yürütülmüştür. Güvenirlik analizi sonucunda iç tutarlılık, test yarılama ve bileşik güvenirlik katsayılarının kabul edilebilir düzeyde olduğu görülmüştür. Alt faktörlere ve ölçeğin geneline ilişkin Cronbach Alfa iç tutarlılık katsayıları: Mantıksal düşünme için .877, İşbirliği için .813, Algoritma için .775, Kontrol için .906, Hata ayıklama için .812 ve ölçeğin geneli için .911 olarak bulunmuştur. Madde analizi sonucunda düzeltilmiş madde toplam korelasyonlarının .41 ile .63 arasında değiştiği, %27’lik alt ve üst gruplar arasındaki ortalama farklarının anlamlı olduğu görülmüştür. Sonuç olarak ölçeğin Türkçe formunun lise ve üstü öğrenim kademesindeki öğrencilerin bilgisayar programlama öz-yeterliklerinin ölçülmesi amacıyla kullanılabilecek geçerli ve güvenilir bir ölçme aracı olduğu görülmüştür.

The Validity and Reliability Study of The Turkish Version of Computer Programming Self-Efficacy Scale

Öz

The purpose of this research is to adapt the Computer Programming Self-efficacy Scale developed by Tsai, Wang and Hsu (2019) to the Turkish language and to present the validity and reliability results. The research was carried out with 297 high school and university students. The original scale consists of 16 items and five factors (Logical Thinking, Cooperation, Algorithm, Control and Debugging). First and second order confirmatory factor analysis were performed to test the construct validity of the scale. Convergent and divergent validity studies were also conducted. It was determined that the internal consistency, split-half and composite reliability coefficients were within acceptable limits. Cronbach’s alpha internal consistency coefficients for the sub-factors and overall scale were; .877 for Logical Thinking, .813 for Cooperation, .775 for Algorithm, .906 for Control, .812 for Debug, and .911 for overall scale. Item analysis showed that the corrected item total correlations ranged between .41 and .63 and the mean differences between top and bottom of 27% groups were significant. As a result, it has been determined that the Turkish form of the scale is a valid and reliable instrument that can be used to measure the computer programming self-efficacy of students at high school and higher levels.
