This document presents the design of a didactic strategy with STS approach, as well as the results of its application, which help in the solution of three difficulties: 1) improper and irresponsible use of social networks and even the exercise of aggressive actions, negatively affecting the peer coexistence; (2) limited analysis and critical positions of information about the armed social conflict and post-conflict; and (3), the little or nonexistent appropriation of the networks social benefits for the educational community, in particular, and society, in general, as in the case of improving coexistence (virtual and face-to-face) and other relationships. Therefore, this strategy aims to generate spaces and activities that, in an interdisciplinary way, can help solve these difficulties, particularly focused on ninth grade students of Nelson Mandela I.E.D. from Bogota.
