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? The evaluation operationalized implementation with fidelity as at least 85 percent of a grade level's students enrolled in ST Math during the year and at least 50 percent of grade-level material covered on average. → Wendt 2019
Evidence¶
Wendt 2019¶
Wendt, S., Rice, J., & Nakamoto, J. (2019). A cross-state evaluation of MIND Research Institute's ST Math program and math performance. San Francisco, CA: WestEd. https://eric.ed.gov/?id=ED601907
q3 · i? · causal · r2
Definitional criterion from the Method section, applied to identify the 239 of 474 schools (in 14 states) with at least one grade level implementing with fidelity; per-grade fidelity rates were 43.0, 42.6, and 46.3 percent for grades 3, 4, and 5.
"implementation with fidelity was considered to have occurred for a grade level when at least 85 percent of the students in that grade level at a school had been enrolled in ST Math during the academic year, and an average of at least 50 percent of the grade-level material in ST Math was covered by those students"
Discussion¶
Related Claims¶
- Schools implementing ST Math with fidelity in at least one grade level showed larger math advantages (ES 0.31-0.35) than matched comparison clusters — related
- Only 17.9 percent of study ERWC teachers taught at least 8 modules with fidelity under the strand criterion, versus 62.5 percent under an activity-count criterion — related
- Among grades that fully implemented ST Math, grades 2, 3, and 5 showed significant CST advantages but grade 4 did not — related
- Grades provided with ST Math have significantly larger proportions of students advanced, or proficient or advanced, on the mathematics CST than comparison grades — related
- Among grades provided with ST Math, only grade 2 showed statistically significant CST advantages; grades 3, 4, and 5 did not — related
- Grade-level clusters provided with ST Math scored higher on state math proficiency rates and scale scores than matched comparison clusters across grades 3-5 — related
