Post-qualitative inquiry (PQI), the latest approach to inquiry in the social sciences and humanities, deviates from the mainstream research methodologies of quantitative, qualitative, and mixed methods. It has completely different philosophical foundations: post-humanism, post-modernism, post-structuralism. By basing on post-onto-epistemologies rather than methodologies, it aims to promote experimentation, creativity, and difference in knowledge production. Although post-qualitative inquiry may not be able to replace the mainstream research approaches, it reveals the possibility of being more open-minded, experimental, and creative in educational research, including language education research.
