This volume contains contributions from leaders in the field of child language in honor of one of the preeminent scholars in the field of child language acquisition, Melissa Bowerman. Melissa Bowerman has had a profound, widespread, and enduring influence on research conducted in the field for nearly 40 years. In addition to being a tribute to Professor Bowerman and her work, the chapters provide the most up-to-date statement of key positions by several leaders in the field of child language development. Fundamental questions in the field are explored in depth, and there are rich analyses of progress in the field in a number of areas, including learning words; crosslinguistic patterning and acquisition of lexical semantics; crosslinguistic patterning and events, paths, and causes; and influences on development. The volume is essential reading for researchers in child language and development, linguistics, psychology, education, and speech pathology, as well as researchers and practitioners specializing in the many specific languages discussed in the book.
The purpose of Grammar for Teachers is to encourage readers to develop a solid understanding of the use and function of grammatical structures in American English. It approaches grammar from a descriptive rather than a prescriptive approach; however, throughout the book differences between formal and informal language, and spoken and written English are discussed. The book avoids jargon or excessive use of technical terminology. It makes the study of grammar interesting and relevant by presenting grammar in context and by using authentic material from a wide variety of sources.
