Teaching students the specialized ways of reading, writing, and thinking within a discipline — rather than generic comprehension strategies alone — improves their ability to comprehend discipline-specific texts.

Subclaims¶

q3 i1 In a cluster-randomised trial across 24 high schools, a semester of disciplinary-literacy science instruction (text-based investigation to build explanatory models) produced small gains in ninth graders' comprehension of new multiple science texts, but no gain in the explanatory essays students wrote. → Goldman et al. 2019

q2 i? In a quasi-experiment in five urban high schools, a six-month document-based history curriculum improved 11th graders' historical thinking, factual knowledge and general reading comprehension compared with textbook instruction (no effect sizes in the abstract). → Reisman 2012

Evidence¶

Goldman et al. 2019¶

Goldman, S. R., Greenleaf, C., Yukhymenko-Lescroart, M., Brown, W., Ko, M.-L. M., Emig, J. M., George, M., Wallace, P., Blaum, D., & Britt, M. A. (2019). Explanatory modeling in science through text-based investigation: Testing the efficacy of the Project READI intervention approach. American Educational Research Journal, 56(4), 1148–1216. doi:10.3102/0002831219831041

q3 · cluster-randomised controlled trial (not pre-registered) · i1 · small effect, d=0.26 (multiple-choice) and 0.32 (multiple-text comprehension) · n=964 students, 24 schools · causal · r2

Schools were randomly assigned, within strata, to deliver the Project READI ninth-grade biology intervention for a semester or to continue business as usual (48 teachers, 12 schools per condition). Intervention students read, discussed and reasoned from sets of science texts to build explanatory models, with teachers making the discipline's reading practices explicit. On texts about topics neither group had studied, intervention students scored higher on a multiple-choice comprehension task (effect size 0.26) and on a multiple-text comprehension assessment (GISA, effect size 0.32), controlling for prior performance. They did not include more concepts or connections in their written explanatory essays, which the authors attribute to too little support for moving from oral argument to independent writing — so the benefit is to comprehension, not yet to disciplinary writing.

Reisman 2012¶

Reisman, A. (2012). Reading like a historian: A document-based history curriculum intervention in urban high schools. Cognition and Instruction, 30(1), 86–112. doi:10.1080/07370008.2011.634081

q2 · quasi-experiment with a control group · i? · no effect size reported in the abstract · n=236 students · causal · r?

Eleventh-grade students in five San Francisco high schools took part in a six-month Reading Like a Historian curriculum, in which a "Document-Based Lesson" had them use background knowledge to question and reconcile historical accounts from several primary sources, instead of textbook-driven lessons. A MANCOVA comparing treatment and control classes found significant effects of the treatment on all four outcomes: historical thinking, transfer of historical thinking to contemporary issues, factual knowledge, and general reading comprehension. Only the abstract was read, so the size of these effects is not recorded here.

Studies bearing on this claim¶

Does teaching a discipline's own reading and reasoning practices on its own texts improve comprehension and disciplinary thinking over usual instruction? This table gathers the studies behind this claim and the 5 narrower claims that bear on it: 5 distinct studies (4 causal, 1 review), q2–q3, 3 of 5 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Discussion¶

Scope and mechanism. Disciplinary literacy rests on the premise that each discipline has its own text structures, epistemic norms, and ways of using evidence — historians source and corroborate documents, scientists attend to procedures and claims, mathematicians parse dense symbolic prose. Instruction that makes these practices explicit is hypothesized to work because it equips learners with strategies matched to the texts they actually encounter, rather than generic strategies that may transfer poorly across disciplines. This connects to broader claims that activation of discipline-specific prior knowledge and cognitive apprenticeship models of expert thinking support comprehension.

Generic vs. disciplinary strategies. A key open question is how much benefit disciplinary literacy adds over well-taught generic comprehension strategy instruction. For adolescent learners with weak general literacy, generic strategies may still yield the larger gains; disciplinary literacy may matter most for students who already have baseline comprehension skills but struggle with discipline-specific texts. This mirrors the expertise-moderation pattern seen elsewhere in the wiki — see expertise reversal effect.

Teacher knowledge as a boundary condition. Disciplinary literacy instruction requires teachers to have deep knowledge of how their discipline uses texts. Where teachers lack this, implementation often collapses into superficial activities (e.g., "vocabulary lists per subject") unlikely to improve comprehension. Related constraints on vocabulary and syntax demands are discussed under accessible vocabulary and syntax.

Lower-level skills as a floor. Disciplinary strategy instruction presumes fluent decoding and word recognition; students who must labor over individual words have few resources left for discipline-specific reasoning — see Automatic word recognition frees resources for comprehension. Interventions should therefore be layered on top of, not substituted for, foundational fluency work.

Text complexity as a moderator. Disciplinary texts often carry heavy conceptual and syntactic loads. Where text demands exceed learners' capacity, disciplinary strategies may not compensate; designers should pair strategy instruction with chunking and other load-management supports — see Cognitive load management.

Evidence status. This page has two evidence entries: a cluster-randomised trial in high-school science (Goldman et al. 2019; small comprehension gains, no gain in written explanations) and a quasi-experiment in high-school history (Reisman 2012; effect sizes not recorded here). Both compare disciplinary-literacy instruction with usual instruction, not with well-taught generic strategy instruction, so the generic-vs-disciplinary question above is untested in the wiki. Further evidence to curate includes studies comparing disciplinary vs. generic strategy conditions on discipline-specific text comprehension, and evaluations in middle school.
