How Computer Simulations Can Assist Model Generation In Students: Providing an Adaptable Structure to Guide Student Learning
Bibliographic record
Abstract
Le Châtelier's principle and chemical equilibrium are considered two of the most difficult topics for students in high school chemistry, and despite the development of numerous simulations, software solutions have met with limited success. We present two case studies of expert teachers teaching Le Châtelier's Principle and show how the findings of the case studies have informed the design of a novel simulation. We have identified several key tactics used by these teachers that are not currently supported or enhanced by available simulations. Based on these studies, we have designed a novel simulation that 1) affords opportunities for model construction with analogies, 2) facilitates model evaluation by providing multiple reaction representations, and 3) guides learning by explicitly requesting predictions from students. This paper reveals strategies to promote model-based learning in chemistry and a design for an educational simulation that has been closely informed by model-based teaching practices

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
