Abstract
This paper discusses the implementation of a joint, end-of-term PBL exercise (a project lab) into our second-year chemical engineering curriculum at University of Toronto through two courses, Applied Chemistry Laboratory I (CHE204) and Communication (CHE299). The activity was designed to help students learn (i) research skills, (ii) how to select appropriate experiment techniques and equipment, (iii) how to design and conduct a research experiment, (iv) how to analyze real-world results, (v) how to communicate using a technical voice, (vi) how to work collaboratively in a group. Students were guided through the project with e-Learning modules, in-class active learning exercises, and written feedback, but were not provided with the type of detailed guidance typically provided in their LBL. Student feedback indicates that they are able to apply their learning from the activity to new contexts in a later assignment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
