There are many students who seem disengaged at school. It has been said that young people are not reading and won’t write anymore than they absolutely must.
Outside school, however, it is a different story. Studies have shown young people are reading and writing incessantly, updating their MySpace/Facebook pages, keeping blogs and WebPages.

In other words they are reading and writing but in different modes and media to the more traditional print literacies of the 20th century. Indeed the definition of literacy is evolving all the time. Literacy can no longer just encompass print-only works. In the 21st century literacy must include digital, hypertext, images and the plethora of communication media that make up the complex systems that bound in today’s world.

The complexity of messages in today’s world means that our students have to not only know how to “read” them but also know enough about them to be critical viewers, with the power to analyse and understand the obvious and more obscure meanings of the messages around them

Students are bringing multi-literacy skills to the classroom and teachers tap into their interests and skills and then enhance their students’ understanding of these various diverse texts. This will enable them to become skilled at critically viewing any of the diverse texts that is presented to them so that they can confidently use all the media around them to learn, clarify and communicate information rather than by passive users who can be coerced, confused and persuaded by the unscrupulous.
