Mixed methods research is an expanding area of interest for researchers across many disciplines, including education and the social and health sciences. In this book, Mertens provides a brief history of the emergence of this field 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. Case studies are presented that 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 mixed methods research can contribute to a more just and equitable future.
