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 i2 One study targeting oral word-reading fluency with the CLLIP program showed an effect size of 0.66. → José L. Arco-Tirado 2024

q3 · i2 · quant-synthesis · r2
Outcome-specific result from a single study (Pallante & Kim, 2013) using the CLLIP model across kindergarten and first-grade classrooms. The article reports an effect size of 0.66 and notes more studies are needed on this core element.
"Results showed an effect size of 0.66, which represents a high effect size following Cohen's (1988) benchmarks or above the 90th percentile in reading following Kraft's (2020)."
Discussion¶
Learner Variables¶
- Reading and Language — outcome: instruction changes it
- Reading Fluency — outcome: instruction changes it
Related Claims¶
- Fluency effects of Fluency Formula™ differ by initial ability: positive for low-ability students (effect size 0.66) and negative for high-ability students (effect size –0.21), both non-significant — related
- The evidence base for Fluency Formula™ consists of a single small randomized controlled trial, with no studies addressing alphabetics or general reading achievement — related
- Fluency interventions for older students show very small effects on rate and accuracy and virtually no effect on standardized comprehension — related
