The guide is designed for volunteer tutors of English as a second language (ESL). It consists of two parts: the guide itself, offering principles and methods for ESL instruction, and a report of the guide's development. The guide begins with by outlining basic principles and classroom considerations of ESL tutoring. The second chapter discusses the role that cultural differences may play in language instruction, and the third chapter offers guidance for establishing realistic short- and long-term goals. Chapter four looks at issues in testing (placement, diagnostic, achievement) and in developing tests. The fifth chapter provides guidelines for placing students in skill level categories, and the sixth suggests competencies corresponding to those categories, for purposes of curriculum development. Teaching techniques and specific ESL methodologies are then described in greater detail. Contains 10 references. (MSE) (Adjunct ERIC Clearinghouse on Literacy Education)
