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.

Discussion¶
Related Claims¶
- Primary school children's multiplication ability falls into three groups: single digit problem solvers, multidigit problem solvers, and high performers. — related
- Retrieval is faster and procedural execution more efficient on addition than on multiplication problems, and these operation effects persist across the primary school years — related
- Between- or within-class homogeneous ability grouping has a small negative effect on low-ability primary students but no effect on other students — related
