Developing A Digital Educational Game Development Self-Efficacy Scale

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.
