RT Journal Article T1 Validity and reliability of an instrument to evaluate the digital competence of teachers in relation to online tutorials in the stages of Early Childhood Education and Primary Education T2 Validez y fiabilidad de un instrumento para evaluar la competencia digital del profesorado en relación a la acción tutorial online en las etapas de Educación Infantil y Educación Primaria A1 Guillén-Gámez, Francisco David A1 Mayorga-Fernández, María Josefa A1 Contreras-Rosado, José Antonio K1 Investigación activa en educación K1 Profesores - Formación profesional K1 Alfabetización digital AB This article demonstrates the validity and reliability of an instrument to evaluate thelevel of digital competence of Early Childhood Education and Primary Educationteachers to carry out online tutorials using ICT resources as part of the educationalprocess during the COVID-19 pandemic. The instrument consists of 35 itemsclassified into five dimensions (A – functions of the tutor with the students; B –functions of the tutor with the teaching staff; C – functions of the tutor with thefamily; D – training in ICT and transfer; E – use of ICT resources). The instrumentwas applied to a sample of 1,098 active teachers from 14 autonomous communitieslocated in Spain. Reliability was measured using Cronbach’s Alpha, the SpearmanBrown Coefficient, Guttman Two Halves, Omega McDonald, and for compositereliability. To check the validity of the instrument, we analysed the validity ofunderstanding, and exploration of dimensionality using Factorial-ExploratoryAnalysis (EFA), and the instrument was adjusted for the different models throughConfirmatory Factor Analysis (CFA). In addition, factorial invariance was evaluatedbased on the variables sex (male/female), type of centre (public/charter school), andtype of teaching staff (Early Childhood Education/Primary Education), as well asexternal validity. The results of the reliability analyses were highly satisfactory and,in relation to the construct validity, the results found a good fit of the model, both inthe internal validity and in the factorial invariance. The final version of theinstrument consists of 25 items.
