How to Differentiate Content for English Language Learners

English Language Learners bring remarkable linguistic and cultural assets to every classroom, and the most effective teachers see differentiation for ELL students as additive — building on what students already know and can do — rather than remedial. That said, academic language acquisition takes time, and content-area instruction that does not account for language development can leave ELL students struggling with the language demands of a task rather than developing the content knowledge the task is designed to build. The challenge for teachers is making appropriate adaptations efficiently, without creating separate curricula for different groups of students.

The most high-leverage differentiation strategies for ELL students work with the existing lesson rather than replacing it. Visual supports — diagrams, graphic organizers, labeled images — reduce language load without reducing cognitive demand. Sentence frames and vocabulary banks give students the language tools to express understanding they may already have conceptually. Multilingual glossaries for key terms allow students to anchor new academic vocabulary to words they already understand. Pre-teaching the key vocabulary for an upcoming reading or discussion gives ELL students the linguistic foothold they need to engage with grade-level content alongside their peers. None of these adaptations require creating a separate assignment; they are layered onto existing materials.

AI tools have made the production of these supports substantially faster. Generating a vocabulary bank for a specific reading, creating a simplified version of a complex text at a target reading level, or producing a set of sentence frames for a discussion activity — each of these used to require significant teacher time or access to commercial ELL support materials. AI tools can produce these adaptations in minutes, leaving teachers to focus on the pedagogical judgment work: deciding which supports are most important for specific students at their current proficiency level, and monitoring how students are using the supports to ensure they are building independence rather than creating dependence.
