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? Gains in letter-word identification and phonological awareness did not differ among the three instructional conditions. → Piasta 2010 q3 i? Posttest emergent reading and developmental spelling showed no significant differences among conditions. → Piasta 2010 (2)

Evidence¶

Piasta 2010¶

Piasta, S. B., Purpura, D. J., & Wagner, R. K. (2010). Fostering Alphabet Knowledge Development: A Comparison of Two Instructional Approaches. Reading and Writing, 23(6), 607-626. https://doi.org/10.1007/s11145-009-9174-x

q3 · i? · causal · r2

Repeated measures ANOVAs in the randomized study found phonological awareness gains (and letter-word identification gains) rose overall but were "not differential across conditions"; all pairwise contrasts had small ds (0.02-0.10).

"Children's phonological abilities increased from pretest to posttest, F(1, 52) = 5.746, p = .010, but, again, these gains were not differential across conditions"

Piasta 2010 (2)¶

q3 · i? · causal · r2

One-way ANOVAs on posttest emergent reading and developmental spelling found "no significant differences among conditions"; both measures had low reliability in this sample (emergent reading α = 0; DST α = .35), warranting caution.

"Contrasts on the emergent reading and developmental spelling tasks showed no significant differences among conditions"

Discussion¶

Learner Variables¶

Phonological Awareness — outcome: instruction changes it

An 11-week teacher-delivered phonological awareness intervention significantly improves kindergarten children's phoneme segmentation, letter knowledge, reading, and invented spelling — reports the opposite
No individual alphabetics outcome reached statistical significance in the WWC analysis — a broader claim this one bears on
For first-grade nonresponders, PALS showed no statistically significant effects on seven alphabetics outcomes compared with adult tutoring — related
Number instruction outperformed both alphabet instruction conditions on number identification gains — related
Technology-enhanced stories show no significant additional effect on code-related literacy skills — related
