Academic Language and Content Literacy
Key Takeaways
- Academic language includes vocabulary, syntax, discourse, text features, and language functions, not just hard words.
- Tier 2 words are high-use academic words across subjects; 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 pair an explicit language objective with the content objective.
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 each subject demands. The EAS expects teachers to make this language visible.
Vocabulary: Tier 2 and Tier 3
Using Beck, McKeown, and Kucan's three-tier framework, Tier 1 words are everyday words rarely needing instruction (dog, run). Tier 2 vocabulary are high-use academic words that cross subjects, such as analyze, compare, infer, contrast, evaluate, and justify. They saturate directions, rubrics, and classroom talk, so misreading them blocks access even when students know the content. Tier 3 vocabulary is discipline-specific: evaporation, organism, or variable in science; denominator, coefficient, or inequality in math.
Tier 3 words should be tied to concepts, visuals, examples, and repeated use rather than memorized as isolated definitions.
Syntax, Discourse, and Functions Across Subjects
Syntax is sentence structure. Academic tasks often require complex sentences using because, although, therefore, if, when, and as a result. Students may grasp a concept yet need help forming the sentence patterns that express the relationship. Discourse is how language is organized within a discipline: 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.
A language function is the purpose for using language, such as describe, sequence, explain, argue, classify, compare, summarize, predict, and evaluate. The EAS rewards answers that name the function hidden inside a content task.
| 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, Content Literacy, and Language Objectives
Content literacy means students learn the reading, writing, speaking, and listening practices specific to a subject. A textbook chapter, primary source, lab report, word problem, poem, and graph each demand 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 how information is organized, and for ELLs they supply context before a dense passage becomes overwhelming.
A language objective states the language students will use to meet the content objective. It should be practical and observable, 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 ENL or bilingual professionals and revisited during instruction so students hear, read, say, and write the target language, not just see it posted.
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, 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 to hear the language in context, try it orally, receive feedback, and then use it in writing or performance. Repeated authentic use turns isolated words into tools for thinking.
Choosing Which Words to Teach
Teachers cannot preteach every unfamiliar word, so the EAS expects strategic selection. Prioritize words that are (1) essential to the lesson's big idea, (2) likely to recur across the unit and across subjects, and (3) not easily inferred from context or cognates. A Tier 2 verb buried in the directions, such as summarize or justify, often deserves attention before a flashy Tier 3 noun that the diagram already defines. Teaching six to ten high-leverage words deeply, with examples, non-examples, and repeated use, beats a glossary of thirty terms students will forget by the next class.
Distinguishing Language Demand From Content Demand
A recurring EAS judgment is separating a content gap from a language gap. If a student can demonstrate the concept through a diagram, manipulative, or home-language explanation but stumbles only when producing English, the gap is linguistic and calls for language scaffolds. If the student cannot perform the underlying thinking in any mode, the gap is conceptual and calls for reteaching the content. Misdiagnosing the two leads to wrong instruction: drilling vocabulary will not fix a missing concept, and reteaching a concept the student already holds wastes time the learner could spend acquiring the academic English to express it.
The credited response usually gathers evidence in more than one mode before deciding. A quick diagnostic move is to let the student show the idea through a drawing, a sorting task, or a brief home-language explanation; if the thinking is intact there, the teacher targets the English language demand rather than the content, and the EAS option that does exactly that will outperform one that assumes a knowledge gap from a single English-only sample.
