Tóm tắt	Triangulated Field Notes is a qualitative data collection technique in which field notes are recorded independently by multiple observers, from multiple vantage points, or at multiple time points and then systematically compared to strengthen the credibility and completeness of observational data. Rooted in Denzin's triangulation framework and Lincoln and Guba's trustworthiness criteria, the approach counters observer bias by cross-checking accounts before analysis begins.	Member checking is a quality assurance procedure in qualitative research in which the researcher shares preliminary findings, interpretations, or analytical themes with research participants and asks whether the findings accurately reflect their perspectives and experiences. Developed by Lincoln and Guba (1985) as a trustworthiness criterion, member checking is considered a key method for ensuring credibility and reducing researcher misinterpretation. The goal is to verify that the researcher has understood participants correctly and that interpretations are grounded in participants' actual meaning-making, not the researcher's assumptions. Member checking can occur at different points in research (after individual interviews, after initial analysis, or after draft findings are written) and take different forms (individual feedback, group validation, interactive discussion).
