Statistical Validation of the “ECODIES” Questionnaire to Measure the Digital Competence of Colombian High School Students in the Subject of Mathematics

Abstract

Education in the 21st century faces the challenge of digitalization; therefore, the acquisition and development of digital skills in students is indispensable, not only for their learning processes but also for their lives. This study aims to validate the test “ECODIES”, which was used to assess the level of development of digital competence in students in a public high school in Bogotá (Colombia). The test is based on the DigCom model and was administered to a sample of 777 students aged between 11 and 18. The results obtained in the exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and reliability analysis show the quality of the test. Therefore, in this study it is concluded that “ECODIES” is a test with the reliability and validity to assess digital competence in the Colombian context; in this way, we hope to gain enough research about this topic to contribute to the development of digital competence in Colombian students. We conducted an instrumental study for the analysis of the psychometric properties of the questionnaire.
