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? Students afraid of bullying 'all the time' in eighth grade had graduation rates 8 percentage points higher at schools at the 85th percentile of bullying reduction versus schools at the 15th percentile. → Kiguel 2023

q2 · i? · causal · r?

Subgroup analysis within the same quasi-experimental study of Chicago Public Schools students, comparing students with a history of victimization (fearing bullying 'most of the time' or 'all the time' in eighth grade) across school percentiles. Graduation rates were "8 percentage points higher at schools at the 85th percentile."

"Students who were afraid of bullying "all the time" in eighth grade had graduation rates that were 8 percentage points higher at schools at the 85th percentile in bullying reduction vs. schools at the 15th percentile."

Discussion¶

Learner Variables¶

Safety — moderator: an instructional effect differs with it

Attending a high school that reduces the fear of bullying raises students' graduation rates — a broader claim this one bears on
Victimized students reported negative school conditions at higher rates than nonvictims — related
Victims of any crime, theft, and violence reported fearing attack or harm at school at higher rates than nonvictims — related
Schools with higher 5Essentials Survey scores, especially more Supportive Environments, are more likely to reduce students' fear of bullying — related
Escaping a bottom-tier school raises four-year graduation rates, by 10 percentage points for top-tier schools and 3 for mid-tier schools — related
