This new title in the McGraw-Hill Second Language Professional Series addresses one of the fundamental concepts of current second language acquisition research, input, in the context of its relationship with grammar instruction. The book introduces readers to input enhancement techniques that help second language learners pay attention to grammatical form while also providing them with the input they need for successful second language acquisition. The author assumes no prior knowledge of second language acquisition on the part of her readers, and presents current theory and research in an informal, reader-friendly style. With its clear organization and concise chapters, this text is ideal for use in a teaching methods course or an introductory seminar on second language acquisition, either on its own or in conjunction with other introductory books.
