Tóm tắt	Longitudinal oral history is a qualitative research design in which the same participants are interviewed repeatedly over an extended period — months or years — using open-ended, narrative-focused conversations. By revisiting participants at multiple points in time, the researcher traces how individuals construct, revise, and reinterpret their personal stories as their lives unfold, capturing not just retrospective accounts but the dynamic, evolving nature of memory and meaning-making.	Phenomenology is a qualitative research approach that investigates how participants live through and make sense of a specific experience. Rooted in the philosophy of Edmund Husserl and extended by Martin Heidegger, it aims to reveal the essential structures of lived experience rather than to measure or predict outcomes. The two most widely applied variants are Husserl's transcendental phenomenology, which seeks universal essences, and Heidegger's hermeneutic phenomenology, which emphasises interpretation within context.
