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? Vocabulary focus showed strong differential effectiveness between good readers and poor decoders, and between good readers and poor comprehenders, with good readers benefiting. → Tetzlaff 2023

q3 · i? · associational · r?
BCH analysis of the subsample (n = 217 students of 52 teachers) regressing posttest reading comprehension on teachers' instructional foci by profile. Table 2 prints vocabulary-focus contrasts GR vs. PC Beta = 0.54 and GR vs. PD Beta = 0.552 with 90% CIs excluding 0; the article reports "Good readers benefit from a focus on vocabulary".
"While none of the instructional foci showed any main effect for all participants, the specific contrasts for the different instructional foci (see Table 2) show strong differential effectiveness of vocabulary training between good readers and poor decoders, as well as between good readers and poor comprehenders."
Discussion¶
Learner Variables¶
- Decoding — moderator: an instructional effect differs with it
Related Claims¶
- An instructional focus on advanced reading abilities benefits poor comprehenders while good readers suffer under that focus — related

- Instructional foci show no main effect on reading comprehension across all students, and reading-motivation focus shows no meaningful differential effectiveness across profiles — reports the opposite
