Mixed Methods Design in Evaluation by Donna Mertens is a useful, well-organized book that explores the numerous applications and benefits of mixed methods approaches. In the words of the volume editors, after examining published evaluation examples, Mertens “concludes with prompts that engage the reader in thinking about how mixed methods can improve social inquiry” (p. xiv). Mertens advocates that mixed methods in evaluation “strengthen the credibility of evaluation findings” (p. 3) and that they “have the potential to be responsive in a dynamic way that is reflective of the complexity found in most evaluation contexts” (p. 177). In this book, Mertens emphasizes the integration of mixed methods in evaluation throughout the text and, using numerous examples, demonstrates diverse strategies for situating mixed methods within various evaluation paradigms.
