Pennenology is to try to catch phénomen from inside, so in psychiatry for exemple what is the inner life of schizophrénique person.a méthode Eugene Minkowski tried to develop in France. GTM is a way in qualitative recherch to find ne'w hypotheise from the matériel you get when doing This recherche. But still you also have a qualitative recherche méthode called IPA AND using phenomelogy but I don't know about it.
Grounded theory was developed as a research methodology by Glaser and Strauss (The Discovery of Grounded Theory, 1967). It was designed to build new theory grounded in the data. Various methods of rigorous data analysis were developed to make this possible including different levels of coding, constant comparison, memo-writing, emergent sampling, and concurrent data gathering and analysis. Phenomenology, on the other hand, developed as a philosophical orientation concerned with the meaning of human experience. Phenomenology can also be a research methodology when the exploration of experience is the main mechanism of the study. The two may seem incompatible. Classic grounded theory is based on positivistic values designed to achieve some semblance of objective certainty. It seeks to build theory with growing levels of conceptualization, whereas phenomenology is based on interrogating the meaning of experience. Some researchers have combined Husserl’s transcendental phenomenology with classic grounded theory. Baker, Wuest, and Stern investigate this combination in their 1992 paper Method Slurring: The Phenomenology/ Grounded Theory Example. Charmaz (Constructing grounded theory: A practical guide through quantitative analysis, 2006) developed a new form of grounded theory based on constructivist values that is more consistent with hermeneutical phenomenology. There is nothing wrong with combining the proven grounded theory methods listed above with a phenomenological orientation in a complex methodology. I recently carried out a study based on the hermeneutical phenomenology of Maurice Merleau-Ponty and Hans Georg Gadamer. The study used phenomenological interviews as the principle data gathering technique and employed the constructivist grounded theory methods listed above. The trick is to demonstrate how grounded theory can be coherently combined with the specific phenomenological orientation used in the study and to show how this results in a methodology that allows you to best answer your research question.
Thank you to all of you. Your answers definitely helped me to better understand the concepts. I am developing my study protocol and I was not sure which framework to follow.
