''Use of social networks provides benefits. 

The key is knowing leverage them''

Social networks encourage participation, collaboration and student interest.  As the popularity of Facebook and other social networking sites continues to grow, educators are se eingtheir potential for use in education, realizing that social networking sites may have the ability to promote both active learning and collaboration (Malony, 2007). In fact, Selwyn (2009) claims that social networking may “benefit learners by allowing them to enter new networks of collaborative learning, based around interests and affinities not   catered for in their immediate educational environment.” Thus, social networking sites may provide a forum for extending the traditional classroom and enabling users to join groups that match individual educational interests. While many educators are enthusiastic about the potential of using social networking for educational purposes, others remain wary of its place in education claiming that social networking sites may disengage students from learning traditional skills and literacies (Brabazon, 2007). Others fear privacy issues may negatively impact or even destroy the traditional roles of the teacher and learner (Sickler, 2007)

It is worth noting Social networks increase the student-teacher relationship and make it more human. Facilitate communication with students in teaching material, as it is very easy to send messages to an entire course or just a student. They enhance student participation, because it is a system they know and love, so that they feel comfortable to use. On the other hand, may enhance the relationship with their own colleagues.
