Yeah, I am genuinely confused how the grandparent comment just glossed over it.
I believe that both COVID and LLMs are disrupting educational metrics. But in terms of which one did more short-term scale damage (i.e, within 4 years), I would wager it was COVID.
Wouldn’t there be recovery? Especially for the cohort that started school after the end of restrictions.
A continuous decline across both COVID and llms points towards a different causal relationship to me. I would be more likely to believe algorithmic social media or computerized teaching tools are to blame, but that is pure conjecture.
