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? The most positive and significant results of the art program were observed among students who attended at least two semesters of workshops, with the dose-response pattern interpreted as consistent with minimal sampling bias. → Pablo Egana-delSol 2023
Evidence¶
Pablo Egana-delSol 2023¶
Pablo Egana-delSol. (2023). The impacts of a high-school art-based program on academic achievements, creativity, and creative behaviors. npj Science of Learning 8:39. https://doi.org/10.1038/s41539-023-00187-6
q2 · i? · causal · r2
PSM analysis comparing AP participants by exposure intensity against matched nonparticipant controls, balancing on demographics including sex, parental education, income, books at home, and prior artistic activity. The authors interpret the scaling relationship as "consistent with minimal sampling bias."
"The most positive and signi ficant results were observed among the group that was treated more intensively (i.e., those who had attended at least two semesters of workshops)."
Discussion¶
Related Claims¶
- Participation in at least two AP workshops produced significant GPA improvements of 0.55 sd overall, 0.61 sd language, 0.36 sd math, and 0.33 sd art — possibly the same claim (merge candidate)
- Participation in at least two AP workshops increased probability of pursuing higher education after high school by 16% — possibly the same claim (merge candidate)
- Longer operating and better implemented community school programs yield more positive results for students and schools — a broader claim this one bears on
