One year of PRIMR produced statistically significant gains in oral reading fluency in grade 1 formal and nonformal schools and grade 2 nonformal schools, in both English and Kiswahili, but not in grade 2 formal schools¶

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? DID estimates showed statistically significant oral reading fluency impacts for grade 1 formal and nonformal schools and grade 2 nonformal schools in both languages, with the effect nonsignificant in grade 2 formal schools. → Stephanie Simmons Zuilkowski & Benjamin Piper 2014
q2 i? Impact magnitude was largest for grade 1 nonformal students and larger in English than in Kiswahili. → Stephanie Simmons Zuilkowski & Benjamin Piper 2014 (2)

q3 · i? · causal · r2
Difference-in-differences analysis of the PRIMR RCT (2312 students in 117 schools at midterm), fit by OLS with covariates and standard errors accounting for nesting of students in schools. The article reports "statistically significant impacts on oral reading fluency" in the named grade and school-type groups.
"Using the DID estimator, we found statistically significant impacts on oral reading fluency in grade 1 formal and nonformal schools and grade 2 nonformal schools for both English and Kiswahili"

q3 · i? · causal · r2
Authors' interpretation of the pattern of DID fluency estimates across grade, school type, and language in the same RCT analysis; the article offers longer Kiswahili words as "one possible explanation for the disparity between English and Kiswahili fluency impacts."
"The magnitude of the impact was largest for grade 1 students in nonformal schools and was larger in English than in Kiswahili."
Discussion¶
Learner Variables¶
- Reading Fluency — outcome: instruction changes it
Related Claims¶
- PRIMR's first-year effects on reading comprehension were positive but inconsistent across language, grade, and school type — related
- The PRIMR literacy intervention had a positive impact on Kenyan pupils' literacy outcomes, including letter sound identification fluency, oral reading fluency, reading comprehension, and the percentage of pupils reading at the Ministry of Education benchmark, though not on all combinations of language, grade, and school type. — a broader claim this one bears on
- Previous non-longitudinal analyses of the PRIMR dataset reported statistically significant impacts on English and Kiswahili outcomes, with impacts ranging from .3 to .5 standard deviations. — related
- The authors caution that PRIMR's first-year effects may not generalize beyond the study's disproportionately peri-urban setting — related
