This research set out to determine the use of a social networking platform, Facebook, as a medium for learning and teaching. Using a combination of the unified theory of acceptance and use of technology (UTAUT) model, Information Systems (IS) success model and the educational use of Facebook theory, a conceptual framework was developed for implementation of mobile learning and teaching. Structural equation modelling (SEM) was used to determine a model for the implementation of mobile learning and teaching. A sample of 330 respondents was used in this research. The data were analysed using structural equation modelling. The aim was to determine to what extent mobile learning is acceptable to colleges of education in Nigeria. Lecturers from a federal college of education in Nigeria were used to test the implementation of mobile learning using Facebook as a medium of communication. Four courses were selected as part of the intervention programme. The research revealed that m-learning significantly improves the teaching and learning conditions in colleges of education, specifically by reducing the inadequacies of physical facilities, and by improving the reading culture and performance of students. The results further indicate that most of the stakeholders are satisfied with the benefits of m-learning and wish to continue using the Facebook and their mobile phones.
