Visual-spatial ability, learning modality and surgical knot tying.
Bibliographic record
Abstract
INTRODUCTION: The ability to mentally rotate an object in 3 dimensions has been shown with an individual's score on the Vandenberg and Kuse Mental Rotations Test. The was to determine whether this Mental Rotations Test could be used to predict performance complex surgical skill - the tying of a 1-handed surgical reef knot. In addition, we learning a spatially complex surgical skill could be achieved more effectively via a computer-based selfdirected learning approach than with a didactic lecture-based teaching method. METHODS: preclerkship medical students at the University of Western Ontario were randomized into computer-based self-directed learning group and a didactic lecture-style learning group. administration of the Mental Rotations Test, the students were taught how to tie a reef knot via the learning modality assigned to their respective group. RESULTS: Students Mental Rotations Test scores were able to tie more surgical knots in the allocated time Students learning how to tie the surgical knot via the computer-based self-directed showed improvement on their knot tying abilities more rapidly than their didactically trained colleagues. CONCLUSION: The ability to mentally rotate an object in 3 dimensions played an important initial learning of a spatially complex surgical technical skill. Our data demonstrated learning was as effective and more practical than traditional lecture-based learning.

How this classification was reachedexpand
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.
