Why Curriculum Writing Matters for Multilingual Learners
As schools become more linguistically and culturally diverse, support for multilingual learners (MLLs) cannot remain an add-on. It must be built into curriculum from the beginning. That means writing curriculum that upholds high expectations, provides purposeful support, draws on students’ linguistic repertoires, and promotes language development while keeping grade-level content at the center. When these elements are planned from the outset, implementation becomes more coherent, instruction becomes more responsive, and access to rigorous learning becomes more consistent.
This is why an ecosystem approach matters. Curriculum is the starting point, but it only works well when instruction, assessment, intervention, leadership, and family engagement are aligned to the same vision. In that kind of system, curriculum becomes more than a sequence of lessons; it becomes the bridge that connects content learning, language development, and meaningful participation in school life.
Expanding Access Through Strategic Curricular Design
Curriculum is one of the strongest tools schools have because it shapes what students are asked to learn and how they are supported in learning it. For multilingual learners, strong curriculum writing begins by anticipating needs rather than retrofitting support later. It makes language demands explicit, embeds scaffolds without lowering expectations, creates opportunities for academic discourse, and builds on students’ home languages and prior knowledge as resources for learning. In this sense, curriculum writing is not only about alignment to standards; it is also about designing access to grade-level content in ways that promote language growth and meaningful participation.
For curriculum writers, this means designing materials that integrate rigor, support, and language development from the start. For curriculum evaluators, it means asking whether materials make grade-level learning accessible and meaningful for multilingual learners through clear language expectations, varied entry points, and authentic opportunities to listen, speak, read, and write in service of content understanding. When those considerations are built in from the beginning, curriculum becomes a foundation for stronger implementation across the school system.
Maintain high expectations by keeping grade-level content central while designing clear pathways into complex learning
Integrate language development into daily subject-area learning rather than treating it as separate from content
Use students’ linguistic repertoires, cultural knowledge, and prior experiences as resources for comprehension and expression
Provide purposeful supports and multiple ways for students to show understanding without reducing the level of challenge
Design for consistent implementation across classrooms, grades, and learning settings so support is built in rather than added later
Core Principles of Responsive Curriculum
Language development should be built into academic learning rather than treated as something students must master before they can participate fully. Strong curriculum makes the language demands of each discipline visible and gives students structured opportunities to develop the vocabulary, syntax, and discourse needed to engage with content. Jim Cummins’ distinction between Basic Interpersonal Communicative Skills (BICS) and Cognitive Academic Language Proficiency (CALP) remains useful in reminding educators that conversational fluency does not necessarily mean students are ready for the language demands of school. At the same time, Guadalupe Valdés has cautioned against treating that distinction as a simple binary or isolating language too narrowly from content. When schools over-curricularize language, they risk fragmenting instruction and separating it from the meaningful contexts in which language develops most powerfully.
This broader view of language also underscores the importance of students’ full linguistic repertoires. Multilingual learners bring home languages, dialects, and culturally rooted ways of communicating that can strengthen reasoning, expression, and comprehension. Responsive curriculum uses these resources to connect prior knowledge to new learning, deepen understanding, and support access to complex ideas. In this way, accessibility and high expectations work together: visual supports, clear models, and purposeful scaffolds help students engage with rigorous content without reducing the level of challenge.
A strengths-based perspective is equally important. Multilingualism is not only a challenge schools must address; it is also an intellectual and cultural resource. When curriculum affirms students’ identities and positions primary languages as tools for sense-making and problem-solving, students are better able to contribute and thrive. Because language develops through active use, curriculum must also create opportunities for collaboration, inquiry, and argument. When students articulate ideas, build on peers’ thinking, and support claims with evidence, they develop language and disciplinary understanding at the same time.
These same practices also strengthen listening and reading comprehension by helping students attend to meaning, follow complex ideas, interpret academic language, and make sense of texts and discussions with greater precision. Assessment, in turn, should focus on what students know rather than how quickly they can navigate the language of a task. That requires tools that help educators distinguish content understanding from language proficiency, along with consistent guidance so that scaffolds, differentiation, and expectations are applied thoughtfully across classrooms.
Practical Strategies for Educators and Interventionists
For teachers and interventionists, this means planning language and content together from the start of instruction, not after difficulties appear. By identifying the language functions and comprehension demands of a lesson—such as comparing, justifying, summarizing, listening for key ideas, or making sense of complex texts—educators can build in supports like sentence frames, visual models, guided peer interaction, and explicit connections between students’ home languages and the language they are learning. These supports are most effective when they are targeted, temporary, and tied to grade-level content rather than used as substitutes for it.
Intervention should also be planned as part of the overall instructional design, not as a separate track that begins only after students struggle. That may include front-loading key concepts and vocabulary, using multilingual visuals or glossaries, and giving students opportunities to rehearse academic language orally before independent writing. This approach works best when interventionists and classroom teachers coordinate closely so that support reinforces the language and concepts students are expected to use in class. In that model, intervention extends access to grade-level learning rather than lowering expectations.
A Vision for Future Leadership
The schools that will best serve multilingual learners are the ones that plan for them at the point of curriculum adoption and implementation, not after classroom use reveals gaps. When schools select materials, they should look for curricula that maintain high expectations, provide meaningful support, draw on students’ linguistic repertoires, and promote language development within grade-level content. They should also anticipate what teachers of multilingual learners will need to implement those materials well, including professional learning, mentoring, collaborative planning, and other forms of ongoing support.
Research strongly supports this conclusion. The National Academies of Sciences, Engineering, and Medicine found that multilingual learners benefit most when language development is integrated with content learning rather than treated as a separate track, and when schools build the professional capacity needed to teach those students well. More recent studies likewise show that grade-level instruction paired with explicit language supports—such as visuals, academic language scaffolds, and structured opportunities for oral and written practice—can strengthen both content learning and language development. Together, these findings reinforce a clear point: curriculum adoption should anticipate multilingual learners’ needs from the beginning, and implementation should equip teachers with the guidance and support required to make that curriculum work in practice.
Suggested Reading
For readers who want to explore the research base behind these ideas, several foundational texts are especially useful. Jim Cummins’ work on academic language and linguistic interdependence remains central, particularly Cognitive/Academic Language Proficiency, Linguistic Interdependence, the Optimum Age Question and Some Other Matters (1979), The Role of Primary Language Development in Promoting Educational Success for Language Minority Students (1981), and Language, Power and Pedagogy: Bilingual Children in the Crossfire (2000). Guadalupe Valdés offers an important complementary perspective on bilingualism, academic language, and schooling; a useful recent entry point is Social Justice Challenges of “Teaching” Languages (2023). Also valuable are Lilly Wong Fillmore and Charles Fillmore’s What Does Text Complexity Mean for English Learners?, Jeff Zwiers’ Building Academic Language, Douglas Fisher, Nancy Frey, and John Hattie’s Visible Learning for Literacy, and the National Academies’ Promoting the Educational Success of Children and Youth Learning English (2017).
