Literacy development is a communal project, and the teaching of literacy skills is embedded across the Ontario curriculum.  However, is the English curriculum that is dedicated to developing the knowledge and skills on which literacy is based - that is, knowledge and skills in the areas of listening and speaking, reading, writing, and viewing and representing.  Language development is central to students' intellectual, social, cultural, and emotional growth and must be seen as a key component of the curriculum.  When students learn to use language, they do more than master the basic skills.  They learn to value the power of language and to use it responsibly.  They learn to express feelings and opinions and to support their opinions with sound arguments and evidence from research.
