Measuring Teachers' and Instructors' Online Teaching Competencies: A Scale Development Study

The aim of this study was to develop a measurement tool that can be used to determine the online teaching competency levels of teachers and instructors. During the validation, the draft scale was applied to online teachers and instructors actively involved in distance education. After the implementation processes, the sample was divided into two groups randomly (n1 = 158; n2 = 144). The first sample was used for Exploratory Factor Analysis (EFA), and the second sample for Confirmatory Factor Analysis (CFA). The EFA highlighted 17 items and 3 factors found in the final scale. Factors were found as Technology, Pedagogy, Ethical and Institution dimensions. The reliability analysis for the whole scale was 0.90, the Cronbach alpha reliability coefficient of sub-dimensions were found to be 0.87, 0.88, 0.78, respectively. In addition, the composite reliability (CR) value of the whole scale was calculated as 0.953 and the CR values for the sub-factors were calculated as 0.877, 0.871 and 0.832, respectively. As a result of the CFA, it was concluded that the scale could be used to measure online teaching competencies of teachers and instructors.
