Academic Language and Content Literacy
Key Takeaways
- Academic language includes vocabulary, syntax, discourse, text features, and language functions.
- Tier 2 words are high-use academic words; Tier 3 words are discipline-specific terms.
- Content literacy means teaching students how to read, write, speak, and listen in each subject area.
- Language functions such as compare, justify, classify, and explain cause and effect should be taught explicitly.
- EAS scenarios favor teachers who connect language objectives to content objectives.
Academic Language and Content Literacy
Academic language is the language students use to learn, show, and discuss content. It is not limited to hard vocabulary. It includes the words, sentence patterns, text structures, discussion norms, and written forms that students need in each subject.
Vocabulary: Tier 2 and Tier 3
Tier 2 vocabulary includes high-use academic words that appear across subjects, such as analyze, compare, infer, contrast, evaluate, and justify. These words are common in directions, rubrics, and classroom talk, so misunderstanding them can block access even when students know the content.
Tier 3 vocabulary is discipline-specific. In science, students may need evaporation, organism, or variable. In math, they may need denominator, coefficient, or inequality. Tier 3 words should be connected to concepts, visuals, examples, and repeated use rather than memorized as isolated definitions.
Syntax and Discourse
Syntax is sentence structure. Academic tasks often require complex sentences with because, although, therefore, if, when, and as a result. ELLs may understand a concept but need support forming the sentence patterns that express relationships.
Discourse is how language is organized in a subject. A science explanation may require claim, evidence, and reasoning. A social studies response may require sourcing, context, and cause-effect links. A math explanation may require defining quantities and justifying steps. Teaching these patterns helps students sound like participants in the discipline.
| Subject | Language function | Possible support |
|---|---|---|
| Science | Explain cause and effect from evidence | Because/as a result frames and labeled diagrams |
| Math | Justify a solution method | Step labels, comparison phrases, precise symbols |
| Social studies | Compare perspectives or sources | Venn diagram, sourcing questions, evidence stems |
| English language arts | Analyze theme or character change | Quote frames and transition words |
| Arts or physical education | Critique performance or technique | Observation checklist and descriptive word bank |
Text Features and Content Literacy
Content literacy means students learn the reading, writing, speaking, and listening practices needed for a subject. A textbook chapter, primary source, lab report, word problem, poem, and graph all require different reading behaviors.
Teach students to use headings, captions, diagrams, glossaries, timelines, bold terms, source notes, and data labels. These features are not extras. They are part of how information is organized. For ELLs, explicit attention to text features can provide context before a dense passage becomes overwhelming.
Language Functions Across Subjects
A language function is the purpose for using language. Common functions include describe, sequence, explain, argue, classify, compare, summarize, predict, and evaluate. The EAS often rewards answers that identify the function hidden inside a content task.
For example, if students must explain why a plant grew differently in two conditions, the function is explaining cause and effect with evidence. The teacher might preteach condition, result, and because, then model how to connect observation to conclusion.
Language Objectives
A language objective states what language students will use to meet the content objective. It should be practical and visible. For example: Students will compare two habitats using the words similar, different, both, and whereas. This does not replace the science objective; it gives students the language path into it.
Language objectives are strongest when planned with ESL or bilingual professionals and revisited during instruction. Students should hear, read, say, and write the target language, not just see it on the board.
EAS Reasoning
When a student struggles, ask whether the barrier is content knowledge, academic vocabulary, sentence structure, text complexity, or discourse. A strong answer gathers evidence before deciding. It adds targeted support and keeps students doing the subject, rather than postponing content until English is perfect.
Short daily routines make academic language stick. Students need chances to hear the language in context, try it orally, receive feedback, and then use it in writing or performance. These repeated uses turn isolated words into usable tools for thinking.
During a science lab, several ELLs can describe what happened but struggle to write why it happened using evidence. Which support best targets academic language?
A social studies teacher notices that ELLs skip captions, maps, and source notes before reading primary-source excerpts. What is the most useful instructional response?
