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.

q2 i? Primary studies showed a wide range of both large positive and large negative effect sizes, and planned moderator analyses (gender, age, type and severity of special need, part- or full-time inclusion, co-teaching) yielded inconclusive results. → Dalgaard 2022

Evidence

Dalgaard 2022

Dalgaard, N. T., Bondebjerg, A., Viinholt, B. C. A., & Filges, T. (2022). The effects of inclusion on academic achievement, socioemotional development and wellbeing of children with special educational needs. Campbell Systematic Reviews, 18, e1291. https://doi.org/10.1002/cl2.1291

q2 · i? · quant-synthesis · r3

Across the review's random effects meta-analyses, the authors report "a moderate amount of heterogeneity" and that single factor sub-group analyses of moderators were inconclusive; no moderator effect sizes are printed.

"There was some inconsistency in the direction and magnitude of the effect sizes between the primary studies in all analyses and a moderate amount of heterogeneity. We attempted to investigate the heterogeneity by single factor sub‐group analyses, but results were inconclusive."
