Social media has taken many sectors including the higher education by storm. However, with wide spread fears that social media may be a distractor to pedagogy, this paper investigated how social media facilitates teaching and learning. Unlike most prior studies which relied much on soliciting mere views from students and lecturers about their intentions to use or not to use social media, this study incorporated Twitter and blogs into two undergraduate courses offered in the Department of Library and Information Science at Mzuzu University which is a public university in Malawi. Data were collected in two ways: first, analysis of blog and Twitter posts by students and second, a questionnaire was sent to 64 students to find out their perception towards the use of blogs and Twitter in a classroom environment. Results suggest that if appropriately deployed, Twitter and blogs are catalysts for the much hyped learner-centred approach to teaching because using these technologies, it emerged that students shared and discussed course materials, posted their course reflections and interacted amongst themselves and with their lecturer 24/7. Challenges faced include cost of internet data bundles, inaccessible Wi-Fi, poor bandwidths and insufficient computers.
