Tóm tắt	A pilot-tested experiment log is a structured research instrument — a systematic journal of experimental procedures, observations, and results — that has been trialed with a small representative sample before full deployment. The pilot phase identifies ambiguous recording fields, impractical time demands, or inconsistent terminology, enabling targeted revisions that improve the log's reliability and completeness before the main data-collection phase begins.	A longitudinal research diary is a structured, ongoing record kept by the researcher throughout an extended study, capturing observations, decisions, emerging insights, and methodological reflections at repeated intervals over weeks, months, or years. It functions simultaneously as a reflexivity tool and a secondary data source, documenting how the inquiry evolves, how researcher positionality shifts, and how contextual changes influence the data collection process across time.
