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? Students with visual impairments show steady upward reading growth trajectories across grades 3-10, but the gap with the national norm stays wide. → Beth Boroson 2017

q2 · i? · associational · r2

The longitudinal MAP data analysis of 224 students with visual impairments found growth trajectories "trending upward at a steady pace" while "the gap between students with visual impairments and the national norm is wide." No effect size is printed.

"While this population's growth trajectories in reading are trending upward at a steady pace, the gap between students with visual impairments and the national norm is wide."

Discussion¶

Learner Variables¶

Access — predictor: learners who differ on it differ in outcomes

Math achievement of BVI students lags sighted peers and the gap widens with age — the general claim this finding bears on, with the studies behind it
Reading achievement was analyzed from 224 students with visual impairments in grades 3–10 in four states over an eight-year period using MAP data — related
Little is known about growth in reading for students with visual impairments as they progress through school — related
The study compared reading growth for students with visual impairments with a nationally normed group of students from the general population — related
Students with visual impairments show accelerated reading growth between 9th and 10th grade while the nationally normed group tends to drop — related
The rate of reading growth for students with visual impairments is suggested to be greater than the national norm — related
Students with visual impairments show lower initial reading achievement in third grade than the national norm — related
