In the report Ungar & Medier 2012/13, statistics show that the users of social media are becoming increasingly younger at age and that social media has become a natural part of children and young people's everyday lives (Statens medieråd, 2013). The purpose of this study is to examine how five teachers experiencing and think about social media's impact on their students and teaching. And also what effects the teachers describe that social media has contributed to in students' identity work. I have, based on the purpose of this study issued following questions: What is social media, according to the teachers?, How do the teachers think about their students' use of social media?, How do the teachers think that social media has influenced their teaching? And how do the teachers describe / experiencing the impact that social media has contributed to in the students' identity work? This study is made through a qualitative method based on interviews with five teachers. The results show that all of the teachers agree that social media is a part of our present. The teachers’ talk about various ways social media has affected their teaching, but most often the discussion has been about values, laws and regulations, concerning the etiquette on social media. The teachers’ believe that social media has had an effect on the children's identity. They believe that children today, focus on appearance, perfection, performance and material objects, which automatically will affect children’s self-image. According to the teachers, social media has created a new way to show appreciation between individuals, where they are appreciated by comments and likes. But let’s all agree that social media is a social place, where children can feel part of their social togetherness and culture.
