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 i2 A study of over 700 students in grades K-5 in a rural fringe public school district in Maryland found significant impacts on Acadience Math (effect size = +0.26) and Grade 2 NWEA MAP Growth Math (effect size = +0.39), while effects on the state MCAP assessment (Grades 4-5) were positive but not statistically significant. → Imagine IM: Evidence Rating 2024

q2 · i2 · causal · r?
Prospective quasi-experimental study in a Maryland rural fringe district with over 700 students in grades K-5, reporting significant impacts on Acadience Math (+0.26) and Grade 2 NWEA MAP Growth Math (+0.39); MCAP effects were "positive but not statistically significant".
"In a rural fringe public school district in Maryland, a study of over 700 students in grades K–5 found significant impacts on Acadience Math (effect size = +0.26) and on Grade 2 NWEA MAP Growth Math (effect size = +0.39); effects on the state MCAP assessment (Grades 4–5) were positive but not statistically significant."
