Higher performing nations teach fewer math topics in greater depth, Andreas Schleicher, who runs the test, told journalists. Students master a topic and then move on, rather than cycling back to the same concept each year, he said.
PISA results matter, writes Robert Rothman. “PISA is designed to measure how well students can apply what they have learned to real-world problems.” In a follow-up study, Canadian students’ results correlated with their success in college and the job market.
The usual excuses don’t apply, he argues. U.S. students aren’t more likely to live in poverty than children in other OECD countries. U.S. 15-year-olds are slightly less likely to be enrolled in school.
