But if the drop between 2018 and 2022 was AS LARGE as the drop between 2022 and 2026, this implies that something happened that was as large as a global pandemic for students' education happened in the last four years. I believe the OP is implying this could have been AI. However, something else could be happening, such as use of phones and other devices or another fundamental problem in the education system.
- Students who entered the education system in the COVID years are still taking tests today. They didn’t automatically relearn everything.
- Schools have not gone back to pre-COVID practices. Online courses, use of digital tools, fewer tests, dropping SAT/ACT requirements, and most of all budget cuts in school districts – all are still happening today.
The trauma from lockdowns does not disappear overnight! It is compounding damage, that gets worse every year!
And we can not just change childrens habits, after we forced them to sit at home for 2 years with nothing but youtube! They missed key developmental phase!
One can try to tease out effects by looking at per-country or per-state breakdowns. It seems to me that:
- there are lots of different long term trends that vary by country
- some seem to have started too long ago to be tick tock or similar
- some countries see a pandemic drop and recovery
- this implies to me that:
(I) the pandemic had a strong temporary effect on average educational attainment (though I have strong priors here), and
(II) other things like long-term trends in teaching approaches, new distractions for students, or availability of AI for ‘cheating’ also have an impact
