Students who use AI for specific schoolwork tasks such as summarizing texts, drafting or conducting research score lower in science than those who do not, by around 20 points on average, a gap the OECD equates to roughly one year of schooling.
At 66%, Singapore's weekly use rate runs 20 percentage points above the OECD average, and only 4% of its students reported never or almost never using AI chatbots for any of the schoolwork tasks PISA examined, against an OECD average of 14%.
Some 46% of Singapore students use AI to conduct preliminary research on a new topic against an OECD average of 31%, 45% to draft text for writing assignments against 29%, and 41% to summarize a text they had to read against 30%.
TechNode Global reported the widest gap was for summarizing reading, where daily users scored nearly 30 points below non-users.
Bloomberg put the drafting comparison at 509 points for students who never or almost never use AI to write assignments against 481 for daily users, a 28-point difference adjusted for socio-economic status. The OECD describes these as associations, and notes that weaker students may be more likely to reach for AI in the first place.
