DESCRIBING AND MEASURING THE ENGINEERING KNOWLEDGE BASED USING CONCEPT DOMAINS
Bibliographic record
Abstract
Abstract – We describe the chemical engineering knowledge base in terms of five distinct concept domains: i) mathematics and computation, ii) conservation, iii) equilibrium and spontaneity, iv) rates, and v) the structure and property of materials. These concept domains underpin the curriculum and evolve from disparate subject domains presented in the first year into a cohesive whole by graduation. The knowledge base for chemical engineering can thus be expressed in terms of achieving threshold concepts related to each of these domains. This formulation of the knowledge base suggests that it may be examined using concept inventory testing. We provide examples of how such testing can be implemented in order to produce meaningful data on students’ level of concept attainment. We believe that this approach may be of interest to others as a robust and sustainable method for the ongoing assessment of CEAB Graduate Attribute 1.

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.
