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? There was no main effect of tutoring condition and no time-by-condition interaction in the repeated measures MANOVA. → Sabatini John P. 2011 q3 i? The data do not support that any program was superior overall or that skill-specific gains mirrored instructional emphasis. → Sabatini John P. 2011 (2)

q2 i? Using within-individual gains replicated over tests (WIGROT), neither group nor individual analyses revealed differences in efficacy between the three instructional programs compared. → Mary Beth Calhoon 2013

q3 · i? · causal · r2

Repeated measures MANOVA of the 148 completers found "no main effect of tutoring condition, F(6, 140) = 0.20, p = .998" and no time-by-condition interaction, so gains did not depend on which of the three programs students received.

"There was no main effect of tutoring condition, F(6, 140) = 0.20, p = .998, nor any interaction with time, indicating that gains were not conditioned on which instructional program students received."

q3 · i? · causal · r2

Discussion of research question 2 states "the data do not support the hypothesis that any of these programs was superior to any other overall" and that skill-area gains were not tied to program; MANOVA results for intervention type were not significant.

"the data do not support the hypothesis that any of these programs was superior to any other overall, nor that gain in particular skill areas were tied to the instructional program. The MANOVA results for intervention type were not significant."

q2 · i? · review · r2

The editorial reports that Scarborough, Sabatini, Shore, Cutting, Pugh, and Katz used WIGROT to identify gainers among adult literacy learners and found "Neither group nor individual analyses revealed differences in efficacy between the three instructional programs"; equivalence was not tested beyond this null.

"Neither group nor individual analyses revealed differences in efficacy between the three instructional programs that were compared."
