Abstract

fetched live from OpenAlex

The goal of the present study was to examine whether young children benefited from having an explicit midpoint reference on the number line after training on ordinal knowledge.Preschool-aged children (N = 84; M = 53 months old) were exposed to one session of ordinal training or spatial training.The results show that children who received ordinal training showed near transfer to an ordinal task and far transfer to a number line task.The results also show that children showed more improvements in the version of the number line task where an explicit midpoint reference was presented than no midpoint was presented.In contrast, children who received spatial training only showed near transfer to a 2-D mental rotation task.These results indicate that the ordinal knowledge of the number system is crucial for successful estimation on the number line task.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
