This paper attempts to explore and improve the success of Facebook technology in undergraduate Sociology classes to enhance students’ engagement. Teaching Sociology in Bangladeshi colleges faces several challenges particularly in using Facebook which has been critically presented in this paper where student engagement has been defined from different aspects i.e. systematically and conceptually. It is found that Facebook is effectively used in various settings for strengthening academic achievements but is not used equally in developing countries like Bangladesh. Nevertheless, the scope of applying ICT technology like Facebook is widening as the use of devices becomes popular gradually. But for achieving the target a suitable plan and sincere efforts is essential which may ensure quality education and the output will be a valuable outcome in the ICT based globalized world
