CapítuloAbstract In this survey, we study the frequency on use of social networks for academic activities and their relationship with the user’s socioeconomic status. The measurement was performed at a single moment, in the summer of 2014, in an unrepresentative sample of 340 students in two of the most important public education institutions in Mexico. After analyzing the results, we identified that there is a frequent use of social networks in the daily life of students, but only a few use of these in their scholar activities. The total of the sample use social networks, most commonly Facebook, YouTube, Google+, Twitter and Instagram. Only some of these networks are used in academic activities such as Facebook, YouTube, Google+, Slide Share while others like Twitter, and Instagram, although popular in everyday life, are not involved in educational activities. We didn´t find a significant correlation between socioeconomic status and the use of social networks in educational activities, however it was found that there may be a influence in the use of some social networks by their peers and teachers .
