Development of scale to measure teachers curriculum assessment

Curriculum guides education and ensures unity and integrity in educational and training activities. Furthermore, it plays a crucial role in providing quality education to students. Education quality is therefore influenced by the quality of the curriculum. In addition to the quality of the curriculum design, its applicability in the classroom is equally important. Since teachers implement the curriculum in class, they are one of the best judges of the curriculum's quality, its applicability, its design, and the benefits derived from implementing it. It is important to assess the quality of a curriculum based on teachers' evaluations. There are numerous studies on teacher program evaluation in the literature, but it is also clear that a comprehensive curriculum evaluation scale is needed. To meet this need, a scale was developed based on teachers’ evaluations. Taking into account the quality and elements of the curriculum, a two-dimensional structure was developed. An independent sample of 279 teachers for exploratory factor analysis (EFA) and 220 teachers for confirmatory factor analysis (CFA) participated in the study. Based on the EFA, 31 items and 8 factor structures were identified. CFA results showed adequate fit indices for the 8-factor structure. As evidence of construct validity, the scale demonstrated convergent and discriminant validity. The Cronbach's alpha and omega reliability coefficients were sufficient for reliability, and the items were discriminatory. The scale was found to be valid and reliable enough to assess the quality of the curriculum based on teachers' views. The scale will contribute in one aspect to assessing the curriculum, and in another aspect to evaluating the outcomes of teacher preparation and in-service training.
