These research methods include philosophical assumptions such as ontology, epistemology, and philosophical assumptions. While ontology is the claim about what knowledge is, epistemology refers to how a researcher recognizes the knowledge (Creswell, 2013). Additionally, how investigators write the facts is referred to as rhetoric while the study procedure is the methodology.
Dr. Patton explains epistemology as the investigation of learning taking a deep insight on how we distinguish what we know. The meaning of this is how human differentiate between what they know and what they do not know. On the other hand, ontology refers to the address of the issue that someone is examining, what makes up the world. Philosophy of science refers to the study of theoretical fundamentals of scientific investigation. It is important for a researcher to be familiar with the philosophy of science to study and offer disapprovals for scientific ideas.
