A Confirmatory Factor Analysis of Digital Competency for Student Teachers of Rajabhat University

Abstract

This research article is part of the research entitled Guidelines for Developing Digital Competency for Student Teachers of Rajabhat University. The purpose of this study was to validate the fitness of digital competency component models for student teachers of Rajabhat University with empirical data. The sample consisted of 900 student teachers of Rajabhat University, selected by multi-stage random sampling. The data were collected by using a 5-point rating scale which the content validity was approved by 5 experts. An index of item-objective congruence ranged from .80 to 1.0. Using Cronbach’s alpha, the reliability of the scale was .991. The data were analyzed by using descriptive statistics and second-order confirmatory factor analysis (CFA). The research findings showed that there were 5 components of the digital competency of student teachers of Rajabhat University i.e., digital literacy, digital usage, the interaction and communication, digital ethics, and the learning management. Each of the five components consisted of three indicators which were consistent with the empirical data: c² = 97.155 (df = 78, p = .070), c²/df = 1.246, CFI = .998, GFI = .986, AGFI = .978, RMSEA = .017, and SRMR = .013. The factor loading of each component ranged from .889 to .97, and the factor loading of each indicator ranged from .755 to .845.
