Literacy is more than reading and writing - it is about how we communicate in society. It is about social practices and relationships, about knowledge, language and culture. Literacy … finds its place in our lives alongside other ways of communicating.
Indeed, literacy itself takes many forms: on paper, on the computer screen, on TV, on posters and signs. Those who use literacy take it for granted - but those who cannot use it are excluded from much communication in today’s world. Indeed, it is the excluded who can best appreciate the notion of ‘literacy as freedom’.
