Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 Country differences on 0-5 number line estimation were large (partial eta² = .28), PAE = 9%, 16%, and 23% for China, Belgium, and the U.S. → Torbeyns 2015
q3 i3 6th graders provided less accurate estimates than 8th graders (mean PAE = 20% and 11%, partial eta² = .20). → Torbeyns 2015

Torbeyns, J., Schneider, M., Xin, Z., & Siegler, R. S. (2015). Bridging the Gap: Fraction Understanding is Central to Mathematics Achievement in Students from Three Different Continents. Learning and Instruction. https://doi.org/10.1016/j.learninstruc.2014.03.002
q3 · i3 · associational · r1
The same Country × Grade ANOVA applied to the 0-5 number line estimation task in the 187-student study showed the full hypothesized ordering China > Belgium > U.S., with printed effect size partial eta² = .28; the Country × Grade interaction was again not significant.
"On this more difficult number line task, Chinese students estimated more accurately than Belgian students, who, in turn, estimated more accurately than U.S. students, PAE = 9%, 16% and 23%, F(2, 186) = 34.46, p < .01, partial eta² = .28."
Discussion¶
Related Claims¶
- On 0-1 fraction number line estimation, Belgian and Chinese students estimate far more accurately than U.S. students, with no Country × Grade interaction — related
- Fraction division showed large country differences (Chinese 91%, Belgian 71%, U.S. 22% correct), while fraction addition showed a Country × Grade interaction — related
- Fraction magnitude understanding, measured by number line estimation, predicts general mathematics achievement beyond fraction arithmetic skill in 5 of 6 Belgian, Chinese and U.S. grade samples, though not among Chinese 8th graders — related
