How Hirsch uses it

Every occurrence, grouped by book and chapter, with the claim it was linked to support and (where the extraction regenerated one) the underlying warrant.

1996 · The Schools We Need
Isabel Beck's research on the effects of long-term vocabulary instruction on lexical access and reading comprehension.
direct Disadvantaged children can only catch up in vocabulary through the direct targeting of specific words to be learned.
ch 4 · empirical_study · swn:ch4_E75
Warrant (implicit): When specific instructional interventions consistently lead to measurable gains in a complex skill like reading comprehension, the content of that intervention is necessary for progress.
could fail ifThe gains might be attributed to the 'Hawthorne effect' or increased student-teacher interaction time rather than the specific vocabulary targeting itself.
Studies by Spiro, Anderson, Shifrin, Beck, Perfetti, and McKeown on the relationship between vocabulary, lexical access, and reading comprehension.
related Comprehension skills are conferred by knowledge and a broad vocabulary.
ch 5 · empirical_study · swn:ch5_E28
Evidence showing that reading comprehension is influenced by long-term vocabulary instruction and lexical access.
direct Vocabulary becomes an increasingly critical determinant of reading ability as children move up through the grades.
ch 5 · empirical_study · swn:ch5_E34
Warrant (implicit): If systematic vocabulary instruction leads to measurable gains in reading comprehension, then word knowledge must be a limiting factor in the decoding process.
could fail ifThe observed reading gains could be caused by the increased background knowledge provided during the context of the vocabulary instruction rather than the lexical access itself.
