Research Design: Qualitative, Quantitative, and Mixed Methods Approaches

Abstract

A challenge faced by graduate programs in the social sciences and humanities is supporting students as they move from a distant fascination with a topic to a defensible and coherent research design. In Research Design: Qualitative, Quantitative, and Mixed Methods Approaches, John W. Creswell addresses this challenge directly, offering a clear structure through which to think, organise, and write a research proposal. The purpose of this third edition is to present the newer design options emerging in qualitative and mixed-methods research alongside the long-standing traditions of quantitative inquiry. Although later editions have refined the mixed-methods discussion, this third edition remains a foundational reference, and the framework it sets out is the one most researchers still return to when justifying a design. Creswell’s framing of research design is not merely a technical discussion of methods; it is a deliberate intersection of philosophical worldviews, strategies of inquiry, and specific research methods. This three-part framework serves as the conceptual anchor of the text. Rather than positioning qualitative and quantitative approaches as opposites, he presents them as points along a continuum, with mixed methods occupying the mediating space between them. His early placement of the philosophical assumptions — post-positivism, constructivism, advocacy/participatory, and pragmatism — signals his central insistence: that methodological choices are grounded in epistemological commitments. For the researcher writing a methodology chapter, the practical lesson is to begin not with the method but with the worldview, and to show explicitly how the chosen design follows from it. This is the single most common omission in student proposals, and Creswell’s framework is most useful precisely as a corrective to it.
