Through an online survey of 624 university students from Manizales, Colombia, this study investigates the use that these university students gave to social networks during the social mobilizations carried out during the national strike in November 2019, in Colombia. Likewise, it consulted on aspects related to the citizen participation of these actors in society. The systematization of the results was carried out through the Question Pro software. It was found that the university students consulted used social networks mainly to support the strike and report abuse of authority through their own and shared posts, with photographs of their friends or Classmates. Although a quarter of them were motivated because the mobilizations generate changes in the country, the achievement of the purpose of these activities is very low. Likewise, the university students consulted thinks that voting in elections continues to be the mechanism for citizen participation with the best results.
