An instrument was validated through factorial structure to measure the advantages, levels of reflection, and communicative competencies of the podcast, as well as to establish the levels of reliability and consistency of the measuring instrument. Likewise, confirmatory analysis was carried out to validate the proposed structural model and establish the relationships of the factors using the PLS-SEM methodology, Partial Least Squares Structural Equation Modeling. It was validated with a sample of 142 teachers. It was demonstrated that there is a causality relationship of the variables, given by the coefficient of determination R2, the level of influence of the independent variables: levels of reflection and advantages; on the dependent variable, communicative competencies; the level of influence of the exogenous variable: advantages with the endogenous variable: levels of reflection in teachers. A high degree of construct validity was shown through the fit indices of the confirmatory factorial analysis.
