Key Issues in Chinese as a Second Language Research presents and discusses research projects that serve as theoretical grounding for improving the teaching and learning of Chinese as a Second Language (CSL) in order to help researchers and practitioners better understand the acquisition, development and use of CSL. With the exception of the first chapter, which is state-of-the-art, each chapter makes an attempt to bring together theory and practice by focusing on theory-building and theory application in practice. The book is organized around areas where most future research is needed in CSL: phonology, semantics, grammar and pragmatics. Comprised of contributions from an international group of scholars working on cutting-edge research, this is the ideal text for researchers, graduate students and practitioners in the area of Chinese as a Second or Foreign Language.
