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? In a behavioural-genetic twin design of children aged 5 to 12 years, children's challenging behaviour (irritability, negativity, impulsivity, distractibility, hyperactivity), but not ability (IQ), was the major source of demand on the teacher. → Bly 2026
q2 i? An experimental study manipulating class grouping in primary schools found students placed in classrooms including children with behavioural difficulties had poorer academic outcomes. → Bly 2026 (2)

q2 · i? · review · r2
The review reports this school-sector twin study, attributing the finding to Houts et al. (2010); the review notes the authors' point that one child presenting behavioural challenges can limit classmates' access to the educator.
"Houts and colleagues ( 2010), using a powerful behavioural-genetic twin design of children aged 5 to 12 years found that children’s challenging behaviour (e.g., irritability, negativity, impulsivity, distractibility, and hyperactivity), but not ability (IQ), was the major source of demand on the teacher."

q2 · i? · review · r2
The review reports this experimental class-grouping study from the school sector, attributing it to Goulas et al. (2024); it is presented as raising hypotheses of similar effects in ECEC.
"Goulas et al., ( 2024) in an experimental study that manipulated class grouping in primary school settings found that those placed in class -rooms including children with behavioural difficulties had poorer academic outcomes."
