This paper explores the benefits and barriers of open platforms in promoting university teaching and learning in Tanzania. Despite the potentials open platforms have in supporting teaching and learning processes in higher learning institutions, there is a continuing debate on their benefits and barriers. This study, therefore, examined staff and students experience on the use of open platforms and technologies in teaching and learning activities in four Tanzanian universities. A mixed approach (quantitative and qualitative) was employed for the study. A cross-sectional survey was used to collect data from a sample of 400 respondents selected through simple random sampling and from 15 purposively selected informants. The study findings suggest that faculty members and students use open platforms for academic discussions, posting and accessing lecture slides and tutorials, sharing materials and scholarly communication. On the basis of these findings, ICT infrastructure investment, training to upgrade skills and knowledge and policies are recommended to be in place to promote the usage of open platforms in teaching and learning. The findings highlight that while open platforms offer significant advantages in accessibility, collaboration, and resource availability, obstacles such as inadequate infrastructure and limited digital literacy hinder their widespread adoption.
