Scientific literacy and contexts in PISA 2006 science
Bibliographic record
Abstract
International assessments contribute to a greater understanding of science education around the world by helping participating countries understand potential changes in policies, programs, and practices in science teaching. In 2006, science was the primary domain for the Programme for International Student Assessment (PISA), supported by the Organization for Economic Cooperation and Development (OECD) and conducted by the Australian Council for Educational Research (ACER). Compared to the school program orientation of Trends in International Math and Science Study (TIMSS), PISA provides a unique and complementary perspective by focusing on the application of knowledge to science and technology-related life situations. The orientation of PISA is one of scientific literacy, a theme of great importance to the science education community.

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.
