Adaptación y validación de un instrumento basado en el modelo TPACK para docentes universitarios

The TPACK (Technological Pedagogical and Content Knowledge) model reflects on the different types of knowledge that teachers must develop to incorporate ICT effectively in their educational practices; therefore, the purpose of this paper was to present the results of the adaptation and validation of a TPACK instrument for university teachers. The final sample consisted of 204 teachers from two institutions in southern Sonora. As part of this process, a Cronbach’s alpha of .96 was obtained for the 36 items of the scale. To determine the construct validity, an Exploratory Factor Analysis (EFA) was performed, which showed four factors that explain 68.57% of the total variance. The original instrument is composed of seven dimensions; to verify this, Confirmatory Factor Analysis (CFA) was performed and a four-factor model was confirmed. The results indicate that it is a valid and reliable instrument for measuring TPACK in university teachers. It is suggested for future research to adjust the instrument for specific areas of study or technologies.
