This book is the first comprehensive investigation of interlanguage pragmatic issues in a primary school context that is based on both primary school teachers' statements on their own teaching realities, views and preferences, and a thorough investigation of materials used by teachers and recommended by teacher educators in the state the primary schools are located in. It offers a contrastive analysis of primary school learners acquiring English in a typical English as a foreign language school context and their age peers in the same state that are exposed to English in a school immersion context.  This book will be of interest to scholars, researchers, educators in higher education that focus on English language teaching, second language acquisition and applied linguistics. It is also intended for students who are planning to become primary school teachers of English as a foreign language.
