สรุป	A Triangulated Research Diary is a qualitative data collection approach in which a researcher's ongoing reflective diary is used as one strand within a triangulated data collection strategy. The diary records observations, decisions, emotions, and emerging interpretations across the study, while at least one other data source — such as interviews, documents, or observations — is collected in parallel. Cross-checking diary entries against other sources increases the credibility and depth of the findings.	Field notes are detailed written records created by researchers during or immediately after direct observation in a naturalistic setting. They capture what is seen, heard, and experienced — including behaviors, interactions, physical environments, and the researcher's own analytic impressions — forming the primary data source for ethnographic and observational studies.
