Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? In pedicle screw placement, AR navigation essentially equalized the novice-expert performance gap, with overall AR accuracy 95% versus 77.5% freehand (P<.05 for both linear and angular deviation). → El Ashry M 2026
q1 i? The review interprets this pattern as consistent with predictions from cognitive load theory and the expertise reversal effect. → El Ashry M 2026 (2)

q2 · i? · review · r3
Prospective cohort (4 surgeons / 80 screws, one experienced surgeon plus one novice per group) using HoloLens 2 with Vuforia 3D registration versus freehand; the review reports 95% versus 77.5% accuracy (P<.05).
"Kong et al [10] demonstrated AR's equalizing effect on novice-expert performance disparity in pedicle screw placement: overall AR accuracy 95% versus 77.5% freehand (P<.05 for both linear and angular deviation)."

q1 · i? · review · r2
The review's own interpretive synthesis, attributed to cognitive load theory and the expertise reversal effect; it is an interpretation, not a directly tested result of this review.
"The observed expertise reversal pattern, AR providing the greatest benefit to novices with diminishing returns at higher levels of proficiency, is consistent with predictions from both cognitive load theory [12] and the expertise reversal effect [14]."
Discussion¶
Learner Variables¶
- Prior Knowledge — moderator: an instructional effect differs with it
Related Claims¶
- The review reports that the isolated-elements mixed instructional method benefits novices but the benefit disappears for experienced learners, and that the imagination effect reverses with expertise — a broader claim this one bears on
- Instructional guidance that helps novices can become redundant or counterproductive as expertise grows. — a broader claim this one bears on
- Reviews report that the split-attention benefit for novices reverses into a redundancy effect for more experienced learners: Kalyuga et al. (2003) cite Kalyuga et al. (1998) and Yeung et al. (1998), and Ginns (2006) cites Kalyuga et al. (1998) — a broader claim this one bears on
- AR guidance improves objective technical accuracy in surgical trainees, most strongly in tasks with high visuospatial demands — related
- Surgical performance improvement after virtual reality simulator training is limited to novice and intermediate trainees, not experienced or expert surgeons — related
