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? A 20-percentage-point increase in Algebra I enrollment produced a 10% increase in algebra credit but raised math failure rates by 3.0 to 8.9 percentage points among low- and average-ability students and lowered math grades. → Allensworth 2009 q2 i? Math test scores were unaffected by taking Algebra I instead of remedial math for any ability group. → Allensworth 2009 (2)

q2 · i? · causal · r2

Results from hierarchical interrupted time-series models with difference-in-difference comparisons, presented as simulations of a 20-percentage-point enrollment increase. The article reports that "Math failure rates increased among low-ability students (3.0 percentage points; p < .01)" and grades declined "the most among average-ability students (0.18 grade points; p < .05)."

"Math failure rates increased among low-ability students (3.0 percentage points; p < .01) and among average-ability students (8.9 percentage points; p < .05). Students' math grades also decreased across ability groups by moderate amounts, declining the most among average-ability students (0.18 grade points; p < .05)."

q2 · i? · causal · r2

Null finding from the same enrollment-effect models: ninth-grade math test scores showed no significant change. The authors note that "Only 7 of 48 questions on the Tests of Academic Proficiency test Algebra knowledge," a possible measurement limitation.

"Math test scores were unaffected by taking algebra instead of remedial math, although it is possible that the test was not sensitive to the change in curriculum. Only 7 of 48 questions on the Tests of Academic Proficiency test Algebra knowledge."
