In this unit, we have traced the evolution and nature of Information Communication and Technology (ICT) and how it impacts our society in terms of activities such as banking, health services and education. Concerns and future directions of ICT use were also raised with support of relevant examples. Subsequently, we discussed how ICT is fashioned as a tool for effective teaching, as well as a tool to encourage students' active participation in the teaching and learning process. In this connection, we also discussed the major theories underlining effective use of ICT in the delivery of lessons across different disciplines. Finally, the unit converged into the thesis of educational technology as a version of ICT, and its role in creating, using and managing appropriate technological processes and resources.
