On Purpose: Studying Written, Oral and Visual Language in Context presents an integrated and comprehensive approach to teaching language that focuses on five main purposes of using language: to inform, to persuade, to create, to argue and to entertain.

The analytical approach of the book focuses on the development of a student's ability to evaluate the purpose, style and effectiveness of language used by a wide range of writers and speakers in a variety of contexts.

On Purpose is also a suitable resource for any language-based courses from Year 10 upwards.
