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 panel judged that none of the five recommendations has more than low-level evidence supporting a causal claim of improved student achievement. → Hamilton 2009
Evidence¶
Hamilton 2009¶
Hamilton, L., Halverson, R., Jackson, S., Mandinach, E., Supovitz, J., & Wayman, J. (2009). Using student achievement data to support instructional decision making (NCEE 2009-4067).

q2 · i? · review · r2
The panel's synthesis of its literature search: of more than 490 citations, 64 used experimental, quasi-experimental, or single-subject designs, and "only six meet the causal validity standards of the What Works Clearinghouse". The panel reports it "cannot point to rigorous research that proves the practices do im- prove student achievement".
"given the status of the research, the panel does not have compel- ling evidence that these recommendations lead to improved student outcomes. As a result, all of the recommendations are sup- ported by low levels of evidence."
