Subclaims¶

q2 i? Non-shared environmental variance statistically significantly decreases with increasing school SES in the model without parental SES. → Kim Stienstra 2024 q2 i? Once parental SES is controlled, the non-shared environmental moderation by school SES is no longer present. → Kim Stienstra 2024 (2)

Evidence¶

Kim Stienstra, Antonie Knigge & Ineke Maas. (2024). Gene-environment interaction analysis of school quality and educational inequality. npj Science of Learning. https://doi.org/10.1038/s41539-024-00225-x

q2 · i? · associational · r3

ACE-moderation Model 2 (school SES only) on the twin sample. The article reports the non-shared environmental moderation as unexpected but statistically significant: "it statistically significantly decreases with increasing school SES".

"Although we did not have expectations on the moderation of non-shared environmental variance, we find that it statistically significantly decreases with increasing school SES (Model 2, Table 2)."

q2 · i? · associational · r3

Model comparison in the same analysis: adding parental SES as moderator (Model 4) removes the school-SES moderation of non-shared environmental variance found in Model 3, attributing it to family SES.

"the decreasing non-shared environmental variance by school SES that we found in Model 3 (Table 2), appears to be attributable to parental SES (see Model 4, Table 2)."

Discussion¶

Learner Variables¶

• Socioeconomic Status — predictor: outcomes differ by group: a gap reflecting circumstances and treatment, not a cause

Related Claims¶

• Non-parametric moderation analyses show more genetic variance in the lowest-quality schools, with only the first-versus-fourth quantile difference statistically significant — related
• Genetic and environmental variance components of educational achievement decrease with increasing parental SES — related
• Genetic variance in educational performance decreases with increasing school SES, partly independent of parental SES — related
• School quality does not moderate genetic and shared-environmental influences on educational performance once moderation by school SES and parental SES is considered — related
