Abstract:
This study investigated a framework for implementing SNS for knowledge sharing in Tanzania's
higher learning institutions (HLIs). The study deployed mixed-methods research, where a
convergent research design was used. This enabled the researcher to collect quantitative and
qualitative data in a similar research phase, but they were analysed differently. A convergent
research design enabled the researcher to compare the findings obtained from quantitative data
with those from qualitative data to ensure rigour. A total of 171 out of 239 targeted postgraduate
students completed an online survey from the four HLIs in Kilimanjaro and Arusha regions,
Tanzania. The study included eight heads of academic departments from the respective HLIs as
interview participants. The study discovered that using SNS for knowledge sharing in HLIs has
several advantages, including facilitating interaction, collaborative learning, and sharing various
types of knowledge among students and lecturers, promoting learning and improving students'
academic performance. However, there are challenges to using SNS in Tanzania HLIs, such as
issues with internet connectivity, a lack of security, a lack of ICT facilities and poor
infrastructure, and a lack of SNS usage policies. Therefore, the study proposes a framework for
implementing SNS for knowledge sharing in Tanzanian HLIs. The study also suggests that all
national policies and guidelines relating to education and ICT use in Tanzania HLIs be reviewed
to include a mandatory section for SNS usage as formal learning platforms in all higher learning
institutions. Finally, the study suggests that HLIs in Tanzania subscribe to internet services from reliable internet providers.
