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? For primary ITT and FSM outcomes, teaching-assistant-led interventions showed higher effect sizes than other interventions, consistent with earlier findings the review cites; this pattern was not observed for secondary ITT effect sizes. → Demack 2021
Evidence¶
Demack 2021¶
Demack, S., Maxwell, B., Coldwell, M., Stevens, A., Wolstenholme, C., Reaney-Wood, S., Stiell, B., & Lortie-Forgues, H. (2021). Review of EEF projects: Evaluation report. Education Endowment Foundation. https://eric.ed.gov/?id=ED625480
q3 · i? · quant-synthesis · r2
Subgroup meta-analysis by direct implementer across the EEF trials. The review reports "higher effect sizes for TA-led interventions than for other interventions" for primary ITT and FSM outcomes, attributing the pattern to mode of delivery and fidelity.
"For primary ITT and FSM outcomes, this review reflects earlier findings (Anders et al., 2017) of higher effect sizes for TA-led interventions than for other interventions, and this is likely to be associated with the mode of delivery and fidelity to the intervention."
