Anonymized learning diary and qualitative aggregate data — LLM-assisted reflective learning diaries

This deposit contains anonymized learning diary records (146 entries, 42 pseudonymous participants) and aggregated qualitative summaries from an undergraduate project-based web engineering course in Mexico (Jan–Apr 2026), where students could report use of generative AI assistants. Student text fields are preserved in Spanish. Analysis scripts and identifiable narratives are not included. Data were collected, anonymized, and deposited by the corresponding author; co-authors of the associated Computer Science Education manuscript contributed to study design, analysis, validation, and writing.
