Although, the benefits of Information and Communication Technology (ICT) in primary schools have been gradually recognised in the past decade, many researchers still hold different or sometimes opposing, views. This paper introduces the history of the educational use of ICT and some theories behind it. The views of people in the supporting and opposing camps will be discussed. A survey was administered to school heads and teachers in Hong Kong to explore their views on the aspects of ICT use. The survey found that teachers have a remarkably less optimistic view than do school heads on many issues. Policymakers should be aware of this perception gap and carefully reexamine any possible issues with ICT deployment. The rationale and method of this study are likely applicable to other educational systems around the world.
