This research methods text for social work is accessible to students in level and writing style, and its paperback format makes it less expensive than most texts on the market. The authors are social work instructors who understand the realities of social work practice and have included many social work practice examples. The text is ideal for a one-semester or quarter research methods course for undergraduate or graduate students with little or no prior knowledge of research. In response to reviewers and students, the fourth edition infuses content in three major areas. First, qualitative research methods are discussed and appropriate examples are offered throughout the book, not just in a single chapter. Secondly, research to evaluate practice, while still the focus of the last two chapters, is discussed alongside research for building a professional knowledge base at many points throughout the text. Third, discussion of ethical issues appears in many other places besides Chapter 2. It receives special emphasis in the discussions of program evaluations and single system research.Yegidis, Bonnie L. is the author of 'Research Methods for Social Workers', published 2001 under ISBN 9780205332335 and ISBN 0205332331.
