Abstract:
Background: The use of social networking sites (SNS) has increased knowledge sharing
among students leading to improved academic performance. Despite the benefits that SNSs
provide in education, their use for knowledge sharing and exchange among postgraduate
students in some Tanzanian tertiary institutions (TIs) faces challenges.
Objectives: To examine the benefits of using SNSs for sharing knowledge and information
among postgraduate students and propose possible solutions to the identified challenges.
Method: This study was conducted using mixed-methods research, employing a convergent
research design. Parallel mixed-methods sampling was used in the study to collect quantitative
data from 171 postgraduates and 30 members of academic staff responsible for teaching and
supervising postgraduates. Qualitative data were gathered from eight heads of academic
departments who were purposively selected.
Results: The findings established that the use of SNSs for knowledge and information sharing
in the TIs selected for the study had expanded postgraduate students’ knowledge bases and
enhanced academic performance. The study indicated that postgraduate students lack reliable
Internet connectivity and a stand-alone policy.
Conclusion: The study recommends that TIs in Tanzania ensure the availability of funds to
make knowledge sharing practices sustainable.
Contribution: The contribution is to the literature for a better understanding of the use of
SNSs in particular and to help decision-makers appreciate how they can prepare provisions
for the use of SNSs.
