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 i? A significant positive interaction was observed between randomised group and pre-test score (p < 0.01). → Styles et al. 2014 q3 i? The model suggests children below 320 on the pre-test performed worse in the intervention group and children above 320 performed better than similar-ability control children, though the report cautions this cannot be stated with certainty. → Styles et al. 2014 (2)

q3 · i? · causal · r2

Pre-specified subgroup analysis in the RCT exploring the interaction between randomised group and pre-test score on the primary outcome; the interaction was significant at p < 0.01, while analysis by National Curriculum level revealed no significant effects.

"Both were carried out and a significant positive interaction was observed with pre -test score (p < 0.01)."

Styles et al. 2014 (2)¶

q3 · i? · causal · r2

Model-based interpretation shown in Figure 4: the lines cross just below the pre-test score of 320, near the Level 3/Level 4 boundary. The report states the gradients of the lines are significantly different but that it cannot say for certain the intervention was detrimental for one ability group and effective for another.

"The model suggests that children of lower ability (below 320 on the pre -test) are likely to perform worse in the intervention group than children of similar ability in the control group."
