And now, information and communication technologies have been deeply involved in this process, even more making extensive use of social networks as a pedagogical tool. This article summarizes a teaching-learning experience with quasi-experimental methodological design that uses the social network Facebook to try to increase the academic performance of students. With this purpose, two groups of a compulsory course were selected in the Faculty of Computer Science, one controlled with the traditional method and the other experimentally controlled with the help of the aforementioned social network.
