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.
q3 i? After controlling for student-level covariates, students in City Connects schools scored 0.15 standard deviations higher in grade 8 mathematics than comparison students (p < 0.01). → O'Dwyer 2016

O'Dwyer 2016¶
O'Dwyer, L. M., Lee-St. John, T., Raczek, A. E., Luna Bazaldua, D. A., & Walsh, M. (2016). Examining the role of early academic and non-cognitive skills as mediators of the effects of City Connects on middle school academic outcomes. SREE Spring 2016 Conference. https://eric.ed.gov/?id=ED567236
q3 · i? · causal · r2
Quasi-experimental ATT-weighted comparison of 3,384 City Connects students and 17,368 comparison students in Boston Public Schools. The article reports "a 0.15 standard deviation difference between grade 8 mathematics scores" favoring City Connects (p < 0.01).
"After controlling for student-level covariates, there was a 0.15 standard deviation difference between grade 8 mathematics scores for students in City Connects schools and students in non- City Connects school (p < 0.01)."
