Passage for Reading & Comprehension: Facebook has become increasingly popular in recent years. There is discussion in the secondary education sector about how Facebook can be used in learning and teaching. The use of social networking sites in schools is of interest because they can have both positive and negative impacts. Facebook has significantly facilitated learning and teaching worldwide.

One of the key benefits of using Facebook in teaching and learning is its capacity to build online communities. Facebook can connect students with peers and teachers, helping them build community: a vital component of student success. For example, in Australia and Singapore, first-year undergraduate students participated in virtual discussions, which helped them connect with their peers and reduced feelings of loneliness and isolation. Research shows that socializing and connecting to others is a crucial component of a satisfying tertiary experience. Thus, Facebook can provide a valuable mode of social interaction for students.

Contrarily, the issue with Facebook concerns safety and privacy. Although Facebook users can control access to their own profiles and data, the process is not easy, and a large proportion of students are unclear about how to do it effectively. The students are then vulnerable to online predators who may have access to contact details, personal information, and photographs. The photographs and videos are a particular concern because of their potential to cause embarrassment and distress. Moreover, students are increasingly concerned about the marketing tools deployed on Facebook and feel a loss of control over their personal data.
