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 i1 FSM-eligible pupils in intervention schools showed a statistically significant negative literacy effect (ES -0.24, CI -0.41 to -0.06), but the report urges considerable caution because no negative impact appeared for low-attaining pupils generally. → Menzies 2016

q3 · i1 · causal · r2

Subgroup analysis of the cluster RCT's Progress in English 12 outcomes for FSM-eligible pupils. Table 1 prints an effect size of -0.24 (95% CI -0.41, -0.06), about -3 months' progress. The report states this adds to the uncertainty of the finding given design limitations and high attrition.

"The analysis did find a statistically significant negative impact on students eligible for free school meals (FSM), however no negative impact was found for lower-attaining pupils more generally, which makes it difficult to hypothesise why PBL might negatively impact FSM pupils specifically."
