2.2 The 21st century is an age of information explosion. This IT-led era connects the world
through the Internet. The wide application of IT has brought much impact on our society, culture
and daily life. It also has an important role in education, changing school education from a largely
textbook-based and teacher-centred approach to a more interactive and learner-centred approach.
Learners are given more information and are able to observe and explore the world outside school,
thus globalised their learning.
