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 i1 Gunn (1996) found negative, substantively important, non-significant effects on WRMT-R Word Identification and Word Attack subtests (domain average effect size –0.33, improvement index –13). → Lindamood Phoneme Sequencing® (LiPS®): Beginning Reading 2015

q3 · i1 · causal · r1

Cluster randomized trial in two elementary schools; analytic sample of 23 first-grade students (11 LiPS, 12 basal comparison). Printed effect sizes: Word Attack –0.35 (–14, p = .57); Word Identification –0.31 (–12, p = .62); domain average effect size –0.33 (–13), not statistically significant.

"Gunn (1996) found effects of LiPS ® on word accuracy/fluency and phonemic decoding that were not statistically significant but were negative and substantively important, as measured by the WRMT-R Word Identification and Word Attack subtests."
