Research in Communication Sciences and Disorders: Methods for Systematic Inquiry, Fifth Edition is a comprehensive yet accessible text meant for instructors and students of research methods in the field of communication sciences and disorders. This innovative book reflects the current emphasis on evidence-based practice in speech-language pathology and audiology. The concepts associated with evidence-based practice are integrated throughout the chapters. Rather than treating empirical research and the search for clinical evidence as separate topics, this text presents both as different applications of a process of scientific inquiry. The format of the chapters reflects the steps a researcher or clinician might complete when conducting an investigation. Included are features that guide students and assist with active learning. Each chapter has a set of updated review questions or case scenarios that can be used as homework, probe questions in class, or as a basis for group activities. In addition, the authors provide lists of supplemental readings from the research literature in the field. As with the previous edition, the fifth edition benefits instructors and students alike with access to a PluralPlus companion website. The website provides convenient lecture slides for each chapter and answers to review questions for instructors. For students, the website lists keywords for each chapter, provides links to supplemental websites and documents, and displays interactive versions of many of the figures within the text.
