The main aim of this paper is to present the benefits of a qualitative research design. This design is based on the interconnected use of research tools and methods, such as interviews, observations, case studies, grounded theory, and interpretative phenomenological analysis. The presented research design has been employed in numerous research projects and has proven highly effective. In this paper, we highlight the advantages of the proposed research design and address its challenges. We consider qualitative qualitative research design to be a vital tool in the field of educational sciences.
