With the emergence of social network sites (SNS), students and teachers of higher education institutions all over the world have been making efforts to meet up with the demands of these information and communication technology (ICT) tools. This paper presents the findings of a study conducted at four private universities in Bangladesh with the aim of exploring the consequences of SNS to the academic and social life styles of students and teachers of these institutions. Random sampling of students and teachers from these institutions was done to get data of the research study. Qualitative and quantitative research methods were used for the study. The findings of the study indicated that the academic and social life styles of students and teachers had several consequences due to their integration with social network sites. However, the positive consequences overweighed the negative consequences. The findings further confirmed that students easily made social interactions with friends and formulated group discussions to exchange academic ideas, and teachers also shared course related materials and assignments with their students. It may be concluded that, even though with few drawbacks, SNS has positive consequences in teaching-learning and on the social life styles of students and teachers of Bangladesh higher education institutions. The findings of the research suggested that students and teachers should continue to use SNS so as to exploit more benefits associated with them. Again as the sample of the study was so small, findings of the study may not be generalized to all Bangladesh higher education institutions. [For full proceedings, see ED571297.]
