The amazing historical collections of didactic instruments of Portuguese secondary schools
Bibliographic record
Abstract
Some years ago, we tried to rescue to daylight some of the historic didactic instruments and apparatuses belonging to the oldest high schools in Portugal and the result was some astonishing perspective of what is usually part of school culture. In some cases, they can be dated back to the last quarter of the nineteenth century. Frequently they can be found displayed in the hallways or some dedicated rooms in the schools. What role do they have at present? Maybe they just remain as pieces of sociability and conversation, records from a scientific educative practice apprenticeship, testimonials of travelling knowledge, normalization standards or examples of the simplicity to display the concepts they were intended to. We will detail on some of those objects more related with chemistry practice. The website then created is being updated, but still remains as a true possibility to visit some of those historical instruments.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
