Decolonization of methodology of Social Science is concerning to the Postcolonial theory, which became part of the critical toolbox in the 1970s, after the Edward Said’s book Orientalism was published. As we know, Decolonization is about “cultural, psychological, and economic freedom” for Native people with the goal of achieving Native sovereignty — the right and ability of Original people to practice self-determination over their land, cultures, and political and economic systems. There have been several particularly active periods of decolonization in modern times, especially during the 20th Century. These include the breakup of the German, Austro-Hungarian, Ottoman, and Russian empires following World War I; of the British, French, Dutch, Portuguese, and Belgian, Italian, and Japanese colonial empires following World War II; and of the Soviet Union in 1991. Nevertheless, any colonial period has an impact on how people think. This has an impact or has an impact on the research methodology. Without a solid theoretical and methodological base, it is impossible to conduct any kind of research.There are a few points. First, how we can concept of hybridity in our debates? The term ‘hybrid’ refers to the concept of hybridity, an important concept in post-colonial theory, referring to the integration (or, mingling) of cultural signs and practices from the colonizing and the colonized cultures. Secondly, we can use the term decoloniality within conduct research. “Decolonization” has also been used to refer to the intellectual decolonization from the colonizers’ ideas that made the colonized feel inferior. Such issues are increasingly discussed under the term decoloniality. Decolonial theory needs a huge intellectual work. The purpose of this Session is twofold: to familiarize auditorium with central concerns in contemporary debates of decolonizing methodology as well as to continue to think through possible futures concerning to decolonial knowledge. Decolonial knowledge perspective covers a wide variety of subjects including philosophy (epistemology in particular), science, history of science, and other fundamental categories in social science.
