Ben Riley reports "that meta-analysis that was published in Nature last year that purported to show a large positive effect of ChatGPT on student learning... has been retracted." The editors "decided to retract this paper owing to concerns regarding discrepancies in the meta-analysis. These issues ultimately undermine the confidence the Editor can place in the validity of the analysis and resulting conclusions. The authors have not responded to correspondence regarding this retraction." I didn't cover it here but it has been cited by others elsewhere.
