Abstract
In this paper, we present an algorithm for reasoning about the sequencing of content for students in an intelligent tutoring system, influenced by McCalla’s ecological approach. We record with each learning object those students who experienced the object, together with their initial and final states of knowledge, and then use these interactions to reason about the most effective lesson to show future students based on their similarity to previous students. We validate our approach through a novel method of validation, providing details of the model of learning used in the simulation and the results obtained in order to demonstrate the value of our model. Beyond confirmation through simulations of student learning, we report on a study with human users and expand on a previous pilot study. We demonstrate the effectiveness of our algorithms for selection of learning objects to solidify the overall defence of our approach.

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
