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? Since 2007 all English state schools must teach synthetic phonics, yet no improvement is evident on PIRLS, PISA, or national SATs; only the Phonics Screening Check itself improved. → Jeffrey S. Bowers 2021 q2 i? PSC mean scores improved only modestly, from 29.5/40 in 2012 to 33.8/40 in 2019, possibly reflecting teaching to the test. → Jeffrey S. Bowers 2021 (2)

q2 · i? · review · r1

Natural-experiment evidence from England, where every state school has been legally required to teach synthetic phonics since 2007 and all children take the Year 1 Phonics Screening Check since 2012. No improvement on PIRLS, PISA, or SATs is reported.

"However, as I detail in my review, there is little or no evidence that the introduction of phonics has improved performance on any of the standardized reading outcomes, namely, the international standardized tests of PIRLS, PISA, nor the national reading tests in England called SATs."

q2 · i? · theoretical · r3

The author computed means from the GOV.UK 'phonics tables' for 2012–2019: mean PSC scores rose from 29.5/40 to 33.8/40, a modest increase despite the pass rate rising from 58% to 82%, possibly due to training to the test such as practicing nonsense words.

"The mean scores improved from 29.5/40 to 33.8/40."
