This fully-updated new edition engages with topics such as orality and literacy, the history of literacy, the uses and abuses of literacy in that history, the analysis of language as cultural communication, and social theories of mind and meaning, among many other topics. It represents the most current statement of a widely discussed and used theory about how language functions in society, a theory initially developed in the first edition of the book, and developed in this new edition in tandem with analytic techniques for the study of language and literacy in context, with special reference to cross-cultural issues in communities and schools.Built around a large number of specific examples, this new edition reflects current debates across the world about education and educational reform, the nature of language and communication, and the role of sociocultural diversity in schools and society. One of the core goals of this book, from its first edition on, has been to develop a new and more widely applicable vision of applied linguistics. It will be of interest to researchers, lecturers and students in education, linguistics, or any field that deals with language, especially in social or cultural terms.
