This chapter discusses the design of qualitative research, emphasizing the interactive and flexible nature of qualitative methods. Unlike traditional quantitative research designs, which often present a fixed set of methods and procedures, qualitative research designs are more dynamic and context-dependent. The author proposes an *interactive* model of research design, which views the components of a study (goals, conceptual framework, research questions, methods, and validity) as interconnected and influencing each other. This model highlights the importance of integrating personal, practical, and intellectual goals, and the role of the researcher's conceptual framework, including existing theory, research paradigms, and experiential knowledge. The chapter also discusses the formulation of research questions, the use of pilot studies and thought experiments, and the integration of these elements into a coherent and valid study. The interactive model aims to provide a more realistic and comprehensive approach to designing qualitative research, ensuring that all components work harmoniously together to achieve the study's goals.This chapter discusses the design of qualitative research, emphasizing the interactive and flexible nature of qualitative methods.
