Abstract
A computer simulation program that utilizes a dynamic analogy to represent Le Chatelier's Principle was studied to investigate how the analogy contributed to students' conceptions of chemical equilibrium. 46 Grade 12 Chemistry students interacted with the simulation and participated in 3 assessments. Statistical analysis of pre and posttests suggested that students strongly held a misconception that the non-favored reaction rate decreases when the favored reaction rate increases and the dynamic analogy of a weigh scale had the potential to reinforce the misconception. Analysis of molecular drawings revealed notable patterns in how the motion, distribution and ratio of molecules are perceived. Other findings on conceptual gains and the analogy are discussed. The implication of this study for educators and developers is that dynamic analogies can assist students, but limitations of the analogy should be discussed and cues in the simulation could assist with mappings to the target domain.

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
