The use of social networking sites in education has drawn attention to stakeholders of education. This Master‟s thesis aims to examine criteria teachers and students use in managing their self-disclosure in social media using Petronio‟s Communication Privacy Management theory. Moreover, self-disclosure in social media and its effect on teacher-student relationships is investigated. Three teachers and three students in secondary level education in Hong Kong were interviewed in depth during October and December of 2012. Moreover, online observation data is undertaken to support the interview data from January 2013 until December 2013. The findings confirm that Facebook could cement teacher-student relationship by magnifying the opportunity of interaction. Findings also suggest that the use of Facebook has positive effects on magnifying teaching resources and creating interactive learning platform. An interesting result emerged showing that teachers receiving encouragement from students‟ comments help them to recover from emotional downside and provide positive affirmation to their teaching career
