Abstract
High Resolution Image Download MS PowerPoint Slide The CHROM Web applet has been used to create a new active-learning exercise in which students design a purification scheme for a recombinant protein using ion-exchange chromatography (IEC). To successfully complete the exercise, students are challenged to apply elementary concepts from acid–base chemistry as well as protein and amino acid structure to devise a scheme purifying the target recombinant protein from other Escherichia coli proteins. By actively applying fundamental principles to solve an unfamiliar problem, students develop higher-level cognitive skills and gain a deeper understanding of key concepts that are difficult to teach effectively through traditional methods. The effectiveness of the exercise in promoting deep learning was assessed by comparing the performance of students in answering questions on acid–base chemistry, amino acid structure, and IEC before and after the completion of the active-learning exercise.

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
