This article reports on two successful communication campaigns in support of the collective construction of the Transformator Peace, both of which are part of the Teaching Plan of the Young Universities for Peace Volunteers Programme (JVUP), of the University Institute for Democracy, Peace and Security (IUDPAS) of the Autonomous University of Honduras (UNAH). The aim was to promote debate, reflection and learning about violence, conflict and peace between students and young people in general, and also, following the ‘two-step Flow of communication theory’, to contribute to the training of activists and peer-to-peer leaders who contribute to the design and implementation of peace actions on their daily social networks, both telematics and always, family, leisure and free time, or educational, work or residential. The study of the Programme was involved both in the design and planning and in the conduct and evaluation of the campaigns that largely exceeded the initial expectations, meeting the stated objectives as demonstrated by the evaluation carried out. In addition to the high media impact generated, the campaigns were of great use in training, reflection and peace action through the establishment of activists and peer-to-peer leaders among the target audiences. Lessons from these experiences constitute a set of good practices for the design of education and communication strategies for peace.
