This article proposes an educational intervention model from Educommunication, integrating communication, pedagogy, information technologies and human development principles. The methods used included, first, an exploratory and quantitative procedure to identify the theoretical foundations of Educommunication and critical attitudes. Then a qualitative procedure was carried out to analyse the reference texts. This resulted in an ad hoc objective corpus that allowed the integration of the main strands of Educommunication and provided epistemic support for the model. The development of the corpus also led to the identification of the field's advances, thus creating theoretical constructs based on the question of how to promote critical attitudes through Educommunication. The model highlights the link between education and ICT development and aims to promote critical attitudes through seven dimensions: media literacy and communication, relationship with others, hypertext, curricular aspects, technology use, methodology and learning objectives.
