Reading and Writing in the Content Areas
Disciplinary literacy
Content-area reading is not generic comprehension applied to textbooks. Disciplinary literacy means teaching the ways of reading, writing, and reasoning specific to a discipline: how scientists use evidence and diagrams, how historians evaluate sources and corroborate accounts, how mathematicians read proofs and word problems. Teachers should teach discipline-specific text structures-description, sequence, compare-contrast, cause-effect, problem-solution-and academic vocabulary.
Text complexity and tasks
Text complexity has three dimensions: quantitative (e.g., readability, sentence length), qualitative (structure, knowledge demands, levels of meaning), and reader/task considerations (purpose, motivation, background). Assign text-dependent tasks that require evidence. Integrate reading and writing: summaries, note-taking, constructed responses, arguments, and explanatory writing. Scaffolds include graphic organizers, chunking, glossaries, sentence frames, and modeled think-alouds-but scaffolds should fade.
Traps
Questions may suggest generic strategies suffice in every discipline, that content teachers are not responsible for literacy, that text complexity equals a Lexile score alone, or that writing belongs only in English class. Another trap is using scaffolds permanently rather than gradually removing them.
Rule of thumb
Ask, "What does a reader in this discipline do with this text?" In a science passage on the water cycle, teach sequence and cause-effect language, have students interpret a diagram, and use a summary frame: "First ___, because ___, which leads to ___." Then students write an explanation using evidence.
Key points
- Disciplinary literacy teaches discipline-specific reading and reasoning.
- Teach common informational text structures explicitly.
- Text complexity includes quantitative, qualitative, and reader/task factors.
- Writing supports content learning and should be integrated across subjects.
- Scaffolds should be temporary and gradually removed.
