In this book, Mertens provides a brief history of the emergence of mixed methods research and numerous examples to illustrate its application in different disciplines and geographic areas.

Mixed methods approaches offer researchers an exciting opportunity to explore new combinations of methods in diverse contexts: the design possibilities are endless and can be incorporated in many different approaches. The book presents case studies to illustrate different philosophical lenses for mixed methods design, including post-positivism, constructivism, pragmatism, transformative, Indigenous, and dialectical pluralism. The book features interviews with researchers about their experiences and practices. They discuss a variety of topics including innovative research design, use of technology and big data, preparation of mixed methods researchers, and how this research can contribute to a more just and equitable future.
