title: Related Data for: Learning data science in elementary school mathematics: A comparative curriculum analysis

description: Background Data literacy is increasingly important in today’s data-driven world. Students across many educational systems first formally learn about data in elementary school not as a separate subject but via the mathematics curriculum. This experience can create tensions in the priorities of learning and assessment given the presence of other foundational mathematics content domains such as numbers, algebra, measurement, and geometry. There is a need to study data literacy in comparison to these other content domains in elementary mathematics. To address this need, we developed a methodology motivated by thinking curriculum theory and aligned with international assessment framework, for comparative analysis across mathematics content domains. This methodology examined increasing levels of cognitive domains from knowing to applying to reasoning across mathematics content domains. Intended, assessed, and attained curricula were analyzed using Singapore as a case study, combined with broader comparisons to attainments in four East Asian countries in TIMSS, an international large-scale assessment. Results We found that learning in the data domain had very limited coverage in intended and assessed curricula in Singapore. However, compared to other mathematics content domains, the data curriculum placed heavier emphasis on higher-order cognitive domains including the use of generally difficult mixed data visualizations. This demanding curriculum in Singapore was associated with the highest attainment in the data domain among average 4th grade Singaporean students relative to students in four East Asian countries in TIMSS, as analyzed by quantile regression. However, lower-performing Singaporean students at the 10th percentile generally did not outperform their East Asian peers. We further found very limited applications of data in other mathematics domains or cross-domain learning more generally. Conclusion Our study offers a comparative analysis of the data curriculum in elementary school mathematics education. While the data curriculum was cognitively demanding and translated to very high average attainments of Singaporean students, the curriculum did not equally help weaker Singaporean students, with implications on current discourse on equity–excellence trade-off in science, technology, engineering, and mathematics (STEM) education. Our study further highlights the lack of cross-domain learning in mathematics involving data. Despite the broad applicability of data science, elementary school students’ first formal experience with data may lack emphasis on its cross-domain applications, suggesting a need to further integrate data skills and competencies into the mathematics curriculum and beyond.

title: SEM Withered Plant (BSE, 2025-12-16) — Kikoh Matsuura (Art–Science Archive)

description: SEM Withered Plant (BSE, 2025-12-16) is a child dataset within the series SEM Withered Plant (BSE Series) by Kikoh Matsuura.

It contains raw, uncompressed BMP images (without embedded scale bars) and JPG preview images (with overlaid scale bars), acquired on 2025-12-16 with a personally owned TECHNEX TinySEM M3-i using the BSE detector under high-vacuum conditions.

This dataset constitutes the primary observation data underlying the art–science work Withered Plant.The images capture the hidden microstructures of a dried plant fragment, prepared with an Au sputter coating and observed at an accelerating voltage of 15 kV with a label magnification of 60×.

By preserving both raw scientific evidence and its artistic context, this record stands as a unique trace at the boundary between art and science.

It links to the parent series record via the “Related works” field (IsPartOf) and contributes to the long-term archival of observation as both scientific evidence and a cultural record.
