   Corrected an incorrect researcher affiliation and study duration, an overly precise timeframe for a well-known skill-acquisition model, and two surgical-training studies that could not be verified

   What the page claimed

   Article described Carl Wieman as being at Stanford for his real 2011 physics education study, when he was actually at the University of British Columbia at the time (he moved to Stanford later in his career), and stated the study's two sections each received 12 hours of instruction, when the real intervention was about three hours over one week. It also presented specific year-ranges (2 to 5 years, 3 to 5 years) for stages of the Dreyfus and Benner skill-acquisition models as if they were fixed figures, when these ranges are approximations that vary across secondary sources rather than precise numbers from the original research. It further described a 2020 Annals of Surgery study with specific figures (47,000 operations, 50 hospitals, a 250-repetition threshold) and a 2013 Stefanidis simulation-training study in the Journal of the American College of Surgeons with specific outcomes, and neither could be located despite the underlying researchers and general research areas being real.

   What was corrected

   Corrected Wieman's affiliation to the University of British Columbia for this study and corrected the intervention duration to about three hours over one week. Softened the Dreyfus and Benner timeframes to accurately reflect that they are commonly cited approximations rather than precise figures. Replaced the Annals of Surgery and Stefanidis study references with accurately hedged general descriptions of the real, well-established research areas they represent.

   Why: Verified against the original Deslauriers, Schelew, and Wieman 2011 Science paper, published summaries of the Dreyfus and Benner skill-acquisition models, and a search of Annals of Surgery and Journal of the American College of Surgeons publication records, which did not surface a matching study for either specific citation.

   In Deslauriers, Schelew & Wieman (2011, Science), the active-learning section scored ~74% vs ~41% (less than double); 2.5 was the effect size, not the score ratio.

   Before

   scored 2.5 times higher on a post-instruction assessment

   After

   scored roughly 74% versus 41% on a post-instruction assessment

   Why: Verified live: body content already correctly states the Deslauriers, Schelew & Wieman (2011) results as 74% versus 41% scores; no '2.5 times' language remains. FAQ field contains no mention of Deslauriers or the score figures. No further action needed.
