Using concepts related to research design while writing thesis and dissertation at universities: questioning the status quo

Different Master's and Ph.D. advisors or supervisors request their students to use different concepts in a research design chapter. The concepts are research methodology, research design, and research method. The supervisors inform their students to use these concepts in combination as research design and research methodology or research design and method or research methodology or research method as a chapter main heading as per their university or department guidelines or their own experience. However, I argue that the concepts must be used consistently worldwide by understanding their differences and similarities. Therefore, this short paper tries to conceptualize the concepts in line with different research methodology books and articles and suggest concepts to be used as a heading of the research design chapter in a thesis and dissertation.
