This chapter discusses the design of qualitative research, emphasizing that traditional models of research design are inadequate for qualitative studies. Qualitative research lacks a clear typology and is not linear or sequential, but rather reflexive and interactive. The author proposes an interactive model of research design that includes five components: goals, conceptual framework, research questions, methods, and validity. These components are interconnected and influence each other, rather than following a fixed order. The model is not just a theoretical construct but a real entity that should be explicitly considered in the design of a study. The model is intended to help researchers understand the structure of their study, plan it, and carry it out effectively. The chapter also discusses the importance of ethical considerations in qualitative research and the role of experiential knowledge in shaping research questions and methods. The author argues that qualitative research is not only useful for understanding the meaning of events and actions but also for identifying unanticipated phenomena, understanding the processes that lead to outcomes, and developing causal explanations. The chapter concludes by emphasizing the importance of formulating research questions that are closely connected to the goals of the study and the conceptual framework, and that are answerable by the kind of study that can be conducted.This chapter discusses the design of qualitative research, emphasizing that traditional models of research design are inadequate for qualitative studies.
