Building Background Knowledge: Essential Strategies for Teaching Language Learners
Building background knowledge helps ELLs connect new concepts to existing understanding
One of the most critical teacher skills for supporting English Language Learners involves building and activating background knowledge. ELLs bring rich cultural and linguistic experiences to the classroom, but may lack specific contextual knowledge that native English speakers take for granted. Effective educators recognize that background knowledge serves as the foundation upon which new learning is constructed.
Research from the University of Texas at Austin’s Meadows Center for Preventing Educational Risk emphasizes that “making connections between students’ prior knowledge and current learning is good teaching for all students. For ELLs, however, teachers need to learn what background knowledge and student experiences are relevant to the topic.” This approach acknowledges that ELLs are not struggling thinkers but rather students navigating content in a non-native language.
Practical Applications for Building Background Knowledge
Pre-Teaching Key Concepts
Before diving into a lesson, introduce essential vocabulary and concepts through visual aids, demonstrations, or brief video clips. This gives ELLs necessary context before encountering these terms in more complex text or discussions.
Making Cultural Connections
Explicitly connect new learning to students’ cultural backgrounds and experiences. For example, when teaching about government systems, reference both U.S. structures and those in students’ home countries to build comparative understanding.
“For ELLs to understand words at more than a surface level, instruction must be extended over time with opportunities to hear, speak, read, and write words across varied contexts.”
Developing these teacher skills requires intentionality and cultural awareness. When planning lessons, consider what background knowledge students might need and how to build bridges between what they know and what they’re learning. This strategy is particularly effective in content areas like social studies and science, where cultural and experiential knowledge significantly impacts comprehension.

Explicit Vocabulary Instruction: Essential Strategies for Teaching Language Learners
Explicit vocabulary instruction helps ELLs develop academic language proficiency
Vocabulary development forms the cornerstone of language acquisition and academic success for English Language Learners. Research indicates that ELLs often need between 12 and 14 exposures to new words to fully integrate them into their working vocabulary—far more than the typical 5-10% of instructional time devoted to vocabulary instruction in most classrooms.
Effective teacher skills in this area involve intentional, explicit, and extended vocabulary instruction that supports content learning. This goes beyond simply defining words to creating multiple meaningful encounters with vocabulary across different contexts and modalities.
Types of Vocabulary to Target
- General Academic Vocabulary: Words that appear across content areas (analyze, compare, evaluate) but rarely in conversational English
- Content-Specific Vocabulary: Terms unique to specific subjects (photosynthesis, democracy, denominator)
- Multiple-Meaning Words: Words whose meaning changes based on context (table, solution, power)
- Word Parts: Prefixes, suffixes, and base words that help students decode unfamiliar vocabulary
Eight-Step Process for Explicit Vocabulary Instruction
- State the word and provide a student-friendly definition using language your ELLs will understand
- Give multiple examples, explaining why each demonstrates the target word
- Provide non-examples, clarifying why they don’t represent the concept
- Facilitate discussion that connects to students’ background knowledge
- Check for understanding through targeted questions
- Have students use target words in speaking and writing activities
- Implement systematic review opportunities over time
- Practice “intentional noticing” of target words across different contexts
These teacher skills require planning and consistency. Creating word walls, vocabulary journals, and visual representations of key terms supports ELLs in retaining and applying new vocabulary. The goal is not just memorization but developing a deep understanding that enables students to use words appropriately in different contexts.
Teacher Tip: When introducing new vocabulary, use cognates (words with similar roots across languages) whenever possible. For Spanish-speaking ELLs, approximately 85.5% of biology terms have Spanish-English cognates, making this an effective bridge to understanding.
Developing strong teacher skills in vocabulary instruction pays dividends across all content areas. When ELLs have robust vocabulary knowledge, they can better access content, participate in classroom discussions, and demonstrate their understanding through speaking and writing.
Comprehensible Input: Essential Strategies for Teaching Language Learners
Making input comprehensible helps ELLs access content despite language barriers
Comprehensible input represents one of the most fundamental teacher skills for supporting English Language Learners. This strategy involves modifying how you communicate so that students can understand the content even when they don’t know all the words being used. The goal is to make lessons accessible without simplifying the cognitive demands or content objectives.
According to language acquisition expert Stephen Krashen, language learning occurs when students receive input that is slightly beyond their current language level (i+1) but made comprehensible through context, visual support, and modified speech. This creates the optimal conditions for both language development and content learning.
Key Techniques for Making Input Comprehensible
Modified Speech
- Slow down rate of speech
- Enunciate clearly, especially word endings
- Use shorter, less complex sentences
- Avoid idioms and figurative language
- Repeat key points using different phrasing
Visual and Physical Support
- Use gestures and total physical response (TPR)
- Incorporate visual aids, realia, and demonstrations
- Employ graphic organizers to structure information
- Model processes step-by-step
- Use multimedia resources to reinforce concepts
Developing these teacher skills requires conscious effort and practice. Many educators naturally speak quickly and use idiomatic expressions that can confuse ELLs. Being mindful of how you communicate—without talking down to students—creates an environment where language learners can access content while developing their English proficiency.
“Understanding of academic content is anchored by oral and written language that focuses on content. A content-rich classroom is also a language-rich classroom.”
The effectiveness of comprehensible input extends beyond just making content accessible. When students understand what’s being taught, they experience less anxiety and are more likely to participate actively in classroom activities. This creates a positive cycle where increased participation leads to more language practice and faster acquisition.
Mastering these teacher skills takes time and reflection. Consider recording parts of your lessons occasionally to evaluate how comprehensible your instruction would be for someone still learning English. Small adjustments in how you communicate can make a significant difference in ELLs’ ability to engage with grade-level content.
Scaffolding and Differentiation: Essential Strategies for Teaching Language Learners
Scaffolding provides temporary support that gradually decreases as students gain independence
Scaffolding and differentiation represent critical teacher skills for meeting the diverse needs of English Language Learners. These complementary approaches recognize that ELLs come to the classroom with varying levels of language proficiency, background knowledge, and learning preferences—all of which affect how they engage with content.
Scaffolding provides temporary support structures that help students bridge the gap between what they can do independently and what they can accomplish with assistance. As students develop proficiency, these supports are gradually removed. Differentiation, meanwhile, involves modifying instruction to address students’ specific language levels, learning styles, and needs.
Effective Scaffolding Techniques for ELLs
- Sentence Frames: Providing partially completed sentences that students can use to structure their responses (e.g., “I predict that _____ because _____.”)
- Graphic Organizers: Using visual frameworks to help students organize information and see relationships between concepts
- Think-Alouds: Modeling thought processes by verbalizing your thinking as you work through a problem or analyze a text
- Guided Practice: Providing structured opportunities for students to practice new skills with teacher support before working independently
- Visual Aids: Using images, charts, and diagrams to reinforce verbal explanations
Differentiation Strategies Based on Language Proficiency
| Proficiency Level | Reading Support | Writing Support | Speaking Support |
| Beginning | Simplified texts, heavy visual support, L1 resources when available | Sentence frames, word banks, drawing + labeling | One-word responses, either/or questions, gestures |
| Intermediate | Leveled texts, highlighted key vocabulary, chunked text | Paragraph frames, transition word lists, graphic organizers | Sentence stems, partner practice, structured responses |
| Advanced | Grade-level texts with strategic pre-teaching of vocabulary | Outlines, models of expected work, targeted feedback | Discussion prompts, academic language frames, extended response time |
Developing these teacher skills requires understanding both the language demands of your content and the proficiency levels of your students. The goal is not to water down content but to provide appropriate support that allows all students to engage with grade-level material.
Implementation Tip: When differentiating assignments, maintain the same learning objectives for all students while varying the process, product, or level of support. This ensures high expectations while providing appropriate scaffolding.
Effective scaffolding and differentiation create an inclusive classroom environment where all students can participate meaningfully regardless of their language proficiency. These teacher skills help ELLs build confidence as they experience success with increasingly complex academic tasks.

Collaborative Learning: Essential Strategies for Teaching Language Learners
Collaborative learning provides authentic opportunities for language practice
Collaborative learning represents one of the most powerful teacher skills for supporting English Language Learners. When structured effectively, peer interaction provides ELLs with authentic opportunities to practice language in a low-anxiety environment while simultaneously developing content knowledge and social skills.
Research consistently shows that increasing the time ELLs spend engaged in academic talk accelerates second-language development. However, simply placing students in groups doesn’t guarantee productive collaboration. Effective teachers carefully structure collaborative activities to ensure that all students—regardless of language proficiency—can participate meaningfully.
Structured Collaborative Learning Approaches
Partner Strategies
- Think-Pair-Share: Students think individually, discuss with a partner, then share with the class
- Turn and Talk: Brief partner discussions in response to a prompt
- Numbered Heads Together: Students in groups number off, discuss a question, then one number is called to respond
- Partner Reading: Students take turns reading and summarizing text passages
Group Strategies
- Jigsaw: Students become “experts” on one aspect of a topic, then teach others
- Collaborative Summarizing: Groups negotiate to create a concise summary of content
- Gallery Walk: Groups rotate to view and respond to other groups’ work
- Project-Based Learning: Extended collaborative work on authentic tasks
Developing these teacher skills involves more than just knowing the strategies—it requires thoughtful implementation that considers language proficiency levels and group dynamics. Strategic grouping of students can create natural language models and support systems within the classroom.
“Peer discussion about content enhances learning for all students, but for ELLs, it provides the essential component of additional oral language practice.”
Supporting Productive Collaboration
- Establish Clear Expectations: Define roles, responsibilities, and participation guidelines
- Provide Language Support: Offer sentence frames, word banks, and model responses
- Structure Turn-Taking: Implement routines that ensure all students participate
- Teach Collaboration Skills: Explicitly model how to ask questions, provide feedback, and build on others’ ideas
- Monitor and Support: Circulate during group work to provide targeted assistance
These teacher skills create an environment where ELLs feel safe taking risks with language while engaging with grade-level content. Effective collaborative learning balances academic rigor with appropriate support, pushing students to extend their language use beyond their comfort zone.
When implementing collaborative strategies, remember that ELLs may initially be hesitant to participate. Starting with structured partner activities before moving to larger groups can help build confidence. Additionally, providing preparation time before discussions gives ELLs an opportunity to organize their thoughts and rehearse their contributions.
By developing these teacher skills, you create a classroom community where language learners are valued contributors rather than passive observers. This not only accelerates language acquisition but also promotes cross-cultural understanding and appreciation.
Formative Assessment: Essential Strategies for Teaching Language Learners
Formative assessment provides ongoing feedback about student progress
Formative assessment represents a critical set of teacher skills for supporting English Language Learners. Unlike summative assessments that evaluate learning after instruction, formative assessment occurs throughout the learning process, providing ongoing feedback that guides instructional decisions and helps students understand their progress.
For ELLs, effective formative assessment must address both content knowledge and language development. This dual focus helps teachers determine whether learning difficulties stem from content misunderstanding or language barriers—a crucial distinction that informs instructional support.
Quick Formative Assessment Techniques
- Exit Tickets: Brief written responses at the end of class that demonstrate understanding of key concepts
- Response Cards: Students hold up cards to indicate agreement, disagreement, or understanding
- Thumbs Up/Down: Simple visual check for understanding
- Think-Alouds: Students verbalize their thought process while solving a problem
- Four Corners: Students move to different areas of the room to indicate their response to a question
- One-Minute Papers: Brief written reflections on what was learned or questions that remain
Assessing Language Development
When working with ELLs, teacher skills must include the ability to assess language development across multiple dimensions. The following framework helps educators observe and document students’ language progress:
| Language Component | What to Observe | Examples |
| Word Level | Understanding and use of general academic vocabulary, discipline-specific terms, and multiple-meaning words | Can the student distinguish between different meanings of “solution” in math versus science contexts? |
| Sentence Level | Comprehension and production of various sentence structures, verb tenses, and grammatical forms | Does the student understand complex sentences with embedded clauses? Can they use appropriate verb tenses? |
| Discourse Level | Ability to understand and produce connected language, including use of transitions, pronoun references, and text organization | Can the student follow a multi-step explanation? Do they use appropriate transitions when writing or speaking? |
Developing these teacher skills allows for more accurate interpretation of ELLs’ performance. For example, a student who struggles to answer a complex question might understand the content but need support with the language structures required to express that understanding.
Important Consideration: When assessing ELLs, distinguish between language proficiency and content knowledge. Provide multiple ways for students to demonstrate understanding beyond traditional written responses.
Effective formative assessment also involves students in the process. Teaching ELLs to self-assess using rubrics, checklists, or reflection prompts helps them develop metacognitive awareness and take ownership of their learning. This builds both academic skills and learner autonomy.
By developing these teacher skills, you create a responsive classroom environment where instruction continuously adapts to meet students’ evolving needs. This cyclical process of assessment and adjustment ensures that ELLs receive the support they need to progress in both language development and content learning.
Implementing Essential Strategies for Teaching Language Learners
Effective implementation combines multiple strategies to create a supportive learning environment
Successfully implementing these essential strategies for teaching language learners requires intentional planning, consistent application, and ongoing reflection. Rather than viewing these approaches as separate techniques, effective teachers integrate them into a cohesive instructional framework that supports ELLs throughout the learning process.
Planning for Integration
- Analyze Language Demands: Identify the vocabulary, sentence structures, and discourse patterns required for each lesson
- Set Language Objectives: Establish clear goals for language development alongside content objectives
- Anticipate Challenges: Identify potential linguistic or cultural barriers and plan appropriate supports
- Select Strategic Supports: Choose scaffolds and differentiation strategies based on students’ proficiency levels
- Plan for Assessment: Determine how you’ll monitor both content understanding and language development
Developing these teacher skills takes time and practice. Start by focusing on one strategy at a time, gradually building your repertoire as you become more comfortable with each approach. Collaborating with colleagues, especially ESL specialists, can provide valuable insights and support during implementation.
How can I balance supporting ELLs while challenging all students?
Maintain high expectations for all students while providing differentiated support. The goal is not to simplify content but to make it accessible through appropriate scaffolding. Many strategies that benefit ELLs—such as visual supports, explicit vocabulary instruction, and collaborative learning—enhance learning for all students.
What if I don’t speak my students’ native languages?
While knowing students’ native languages can be helpful, it’s not necessary for effective instruction. Focus on making your English instruction comprehensible through visuals, gestures, and modified speech. Learn key phrases in students’ languages as a sign of respect, and use translation tools strategically when needed.
How can I find time to implement these strategies in an already packed curriculum?
Rather than viewing these as additional components, integrate them into your existing instruction. For example, incorporate vocabulary instruction into your content teaching, use collaborative learning for content review, and embed formative assessment throughout lessons. Over time, these approaches become part of your teaching routine rather than separate activities.
Remember that developing effective teacher skills for supporting ELLs is an ongoing process. Reflect regularly on what’s working and what needs adjustment, seeking feedback from both colleagues and students. This continuous improvement approach ensures that your instruction evolves to meet the changing needs of your language learners.
