From the Flood to the Essence: Filtering and Transforming Authentic Data Into Relevant Information

This is a poster presented at the 7th Shaw-IAU Workshop on Astronomy for Education, organised by the IAU Office of Astronomy for Education (OAE, https://astro4edu.org/shaw-iau/7th-shaw-iau-workshop/). Title: From the Flood to the Essence: Filtering and Transforming Authentic Data Into Relevant Information Presenter:José Antonio D'Santiago García (Universidad Nacional Experimental Rafael María Baralt) Astronomy education faces data overabundance, with only a fraction being useful. To tackle this challenge, the RARE rubric—based on relevance, authenticity, robustness, and ethics—filters information and ensures quality. Applying RARE, irrelevant data is discarded, formats are normalized, and educational kits are structured for classroom use. This method transforms raw files into effective teaching tools, strengthening critical analysis and reducing information overload in astronomy education. About the 7th Shaw-IAU Workshop:The 7th Shaw-IAU Workshop took place 18 - 21 November 2025. The Shaw-IAU workshops focus on astronomy education for primary and secondary school students and teacher training both in universities and in service. This year's Education focus session on Teaching with authentic data and the Science focus is on Galaxies.More details can be found on: https://astro4edu.org/shaw-iau/Keep up to date with future Shaw-IAU Workshops and other opportunities at the IAU Office of Astronomy for Education by joining our mailing list https://astro4edu.org/mailing-list/ Follow the IAU OAE on Bluesky and Facebook under @astro4edu
