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 Preschool children taught letter names and sounds together made larger letter name production gains than children taught letter sounds only (d = 0.53). → Piasta 2010

q3 · i2 · causal · r2
Randomized experiment with 58 preschoolers blocked by letter knowledge and assigned to LNLS, LS, or number conditions; repeated measures ANOVA interaction contrast showed the letter name production gain difference "favoring the LNLS condition (d = 0.53)".
"Interaction contrasts indicated differential gains in letter name production between children in the LNLS condition and those in the LS condition, F(1, 52) = 3.129, p = .041, favoring the LNLS condition (d = 0.53)."
Discussion¶
Learner Variables¶
- Alphabet Knowledge and Print Awareness — outcome: instruction changes it
