Creswell (2006) emphasized the importance of philosophical assumptions, the researcher's worldviews, paradigms, or set of beliefs, and interpretive and theoretical frameworks in qualitative studies. These shape the whole qualitative research design process – especially in the conduct of inquiry.
To simplify our discussion, we will be downsizing the terms into (1) assumptions; (2) paradigms; and (3) frameworks.
The three elements often overlap and complement each other – which can be confusing as they are used interchangeably sometimes. Thus, to establish their differences, we must look into their specific purposes.
This is the first element that shapes the overall idea of a research topic. These assumptions make explicit the practical choices that the researchers decide in designing and conducting the research from its purpose to the methods to be utilized.
These are the worldviews and beliefs that guide the researchers in writing their study.
The researcher provides a lens aimed to understand specific issues or topics, usually those that concern underrepresented or marginalized groups, on all aspects of a research project.
