Nowadays, social networking is becoming a more and more powerful tool for students for communication, sharing of information and discussions on various topics. The study presented in this article investigates the extent to which teachers from different European countries use social networking sites in their teaching practice for different purposes and what their attitude is towards the use of social networking in higher education in general. The study is intended to seek clarity on the issues, whether the use of social networks is related to teacher information about social networking sites; their participation in interest groups and research for the use of social networks in education; and whether the results obtained from the survey vary according to the country. For this purpose, the statistical software IBM SPSS Statistics is used. On the other hand, the study explores specific areas of the use of social networking in higher education, with an emphasis on their efficacy.
