Starting from the premise that design is a thinking process comprising the creation of an entity, according to Miller (1988), I have conducted a participatory research with third semester undergraduate students of Social Communications at the Pontifical Catholic University of Rio de Janeiro . The research is focused on interactive processes of teaching/learning linked to the New Digital Technologies for Information and Communication (NTDICs). As a professor of three classes of Communication Skills II, I have developed the professortexto.blog as a mediation tool, which has provided me with a digital interface to interact with my students. This work describes and analyzes the interdisciplinary experience lived, simultaneously, by the participants in the classroom and virtual ly. It concludes that teachers who manage NTDICs play the role of cognitive designers as they are supposed to plan and maintain dialogical bridges to guide and direct the students’ research projects in order to develop their knowledge.
