PIEDADE, João  y  DOROTEA, Nuno. VALIDATION OF THE SCALE OF DIGITAL TECHNOLOGIES USE IN SCHOOL MANAGEMENT. ETD - Educ. Temat. Digit. [online]. 2021, vol.23, n.3, pp.757-775. ISSN 1676-2592.  https://doi.org/10.20396/etd.v23i3.8657850.

This article reports the validation process of a frequency scale in the use of digital technologies by Portuguese school principals in their professional practices. This scale developed by the authors was previously validated by 3 specialists in school management, and then applied to the sample composed of 133 school principals of Portuguese primary and secondary schools. The metric quality of the scale was evaluated by the analysis of three indicators: (i) the sensitivity of the items by calculating the values of asymmetry and kurtosis, (ii) the validity using exploratory factor analysis with varimax rotation, and (iii) the internal consistency by calculating Cronbach's alpha. The results are revealing good quality metric scale and can allow its use with a favorable degree of confidence.

Palabras clave : Digital technologies use scale in school management; School principals; Digital technologies in education; School management; Factor analysis.
