Abstract

In this research, it is aimed to develop valid and reliable Digital Educational Game Development Self-Efficacy Scale (DEGDSS). In this context, the item pool was formed in line with the related literature. After that, the content validity ratio calculated for each item according to experts’ opinions. The first draft of DEGDSS composed of 24 items was applied to 418 participants for validity and reliability studies. The data were analyzed through SPSS. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted to identify the construct validity of DEGDSS. The Kaiser-Meyer-Olkin (KMO) coefficient of the EFA was calculated as .965 and the Bartlett Sphericity Test was found significant (p=.000). As a result of the analysis of EFA, it was found that the 21-item-scale has a two-factor structure defined as Education and Game Development and these factors account for 70.25% of the total variance. As a result of item analysis conducted to determine the level of discrimination of items of the scale, the difference between the items was found to be significant at .01 level. Cronbach alpha reliability coefficient of the scale was calculated as .972. As a consequence of the CFA, the model was acceptable.

Dijital Eğitsel Oyun Geliştirme Öz-Yeterlik Ölçeğinin Geliştirilmesi

Abstract

Bu çalışmanın amacı geçerli ve güvenilir bir Dijital Eğitsel Oyun Geliştirme Öz-yeterlik Ölçeği (DEOGÖÖ) geliştirmektir. Bu bağlamda ilk olarak alanyazın taraması yapılmış ve madde havuzu oluşturulmuştur. Sonrasında, uzman görüşlerine göre her bir ölçek maddesi göz önünde bulundurularak kapsam geçerlik oranı hesaplanmıştır. 24 madde içeren ilk taslak ölçek, 418 kişiye uygulanarak geçerlik ve güvenirlik çalışmaları yürütülmüştür. Veriler SPSS programı kullanılarak analiz edilmiştir. DEOGÖÖ’nün yapı geçerliğini test etmek amacıyla Açımlayıcı Faktör Analizi (AFA) ve Doğrulayıcı Faktör Analizi (DFA) yapılmıştır. AFA’ya uygunluğu test etmek için Kaiser-Meyer-Olkin (KMO) katsayısı .965 olarak hesaplanmış ve Bartlett Küresellik Testi p =.000 düzeyinde anlamlı bulunmuştur. AFA analizi sonucunda 21 maddeden oluşan ölçeğin Eğitim ve Oyun geliştirme şeklinde tanımlanan iki faktörlü bir yapıya sahip olduğu ve bu faktörlerin toplam varyansın %70.25’ini açıkladığı saptanmıştır. Ölçek maddelerinin ayırt edicilik düzeylerini belirlemek amacıyla yapılan madde analizi sonucunda, maddeler arasındaki farkın .01 düzeyinde anlamlı olduğu ortaya çıkmıştır. Son olarak ölçek için Cronbach alfa güvenirlik katsayısı .972 olarak hesaplanmıştır. DFA sonucunda, model kabul edilebilir düzeydedir.
