Curriculum-grounded authoring and learning diagnosis
Curriculum standards, concept dependencies, original items and explainable scoring organized as reliable education-model data.
Task understanding before scale
An education model needed to distinguish concept mastery, reasoning errors and incomplete expression rather than mark only final-answer correctness. Subject teachers mapped curriculum standards to a knowledge graph, authored original items and supplied reference solutions, step-level rubrics and misconception patterns. A second teacher solved independently, while evaluation researchers used model pilots and item-response analysis to check discrimination, bias and scoring agreement.
Curriculum, concept dependencies and capability targets aligned
Reference, step rubric and misconception set delivered together
Teacher solve, model pilot and difficulty-bias calibration
One structure aligns the questions asked by model, data, procurement and security teams.
Curriculum standards, concept dependencies, original items and explainable scoring organized as reliable education-model data.
Curriculum standards, knowledge graphs, original items, learner-style answers and step rubrics
Teacher authoring, independent solve, misconception modeling, model pilots and item-response analysis
Representative batch of 1,600+ tasks across six difficulty tiers and multiple subjects
Curriculum alignment × original authoring × difficulty calibration; Teacher solve, model pilot and difficulty-bias calibration
Curriculum, concept dependencies and capability targets aligned; Reference, step rubric and misconception set delivered together; Step-rubric agreement above 93%; low-discrimination and biased items reworked before release
