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? Students who started with greater proficiency in one domain tended to grow at a somewhat faster rate in the other domain. → Scammacca Nancy 2020

q3 · i? · associational · r2
From the conditional LGC models, which included math quartile in the reading model and reading quartile in the math model to test cross-domain effects of initial status on growth.
"math quartile was a positive predictor of reading slope and reading quartile was a positive predictor of math slope, indicating that students who started out with greater proficiency in one domain tended to grow at a somewhat faster rate in the other domain."
Discussion¶
Related Claims¶
- Students with low initial reading and math proficiency grew faster over two school years than students with higher initial proficiency, with the inverse relation stronger in math than reading — reports the opposite
- Despite faster growth, students with low initial proficiency remained well below higher-proficiency peers after two school years, conforming to a pattern of stable differences in both reading and math — reports the opposite
- In Han students, higher initial metacognitive knowledge predicted both a higher starting point and a faster growth rate of vocabulary breadth — related
- In Yao students, metacognitive knowledge and vocabulary breadth showed a common growth trend: higher initial MCK predicted higher initial VK, and faster MCK growth predicted faster VK growth — related
