Abstract
The purpose of this study is to determine whether viewing narrated video clips improves student learning. The studywas conducted with undergraduate, mostly Biology majors, in an Animal Physiology course held in successivesemesters. When both classes were given the same face-to-face lectures and identical online resources theirperformance on an exam with the same multiple choice questions was not statistically different (two-tailed, unpairedt-test). However, when one group was also given unlimited online access to narrated video clips, these studentsperformed statistically better on a second exam with identical multiple choice questions. An attitudinal surveyshowed that students used the video clips as an introduction to the interactive animations and simulations and asstandalone mini-lectures, and they indicated that viewing the clips was the best and most efficient way to learnphysiological concepts. While this study used narrated video clips to augment traditional face-to-face instruction,they could be used in a flipped-class, a blended class, and for distance learning.

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
