Language is Central to Learning
Key areas of instruction: Vocabulary knowledge – an important predictor of reading fluency and reading comprehension for ELLs and non-ELLs (Grabe, 1991; McLaughlin, 1987)Academic language – critical for reading and understanding content

Policy Context ofLanguage Development Instruction
Schools must provide instruction that allows ELLs to acquire content-area knowledge while they are developing proficiency in English (NCLB, 2001).
Funded by U.S. Department of Education
Principles of Vocabulary Instruction
Teach high utility words that appear often across content areas and are key to comprehension.Present definitions and examples of use in context.Provide multiple exposures to meaningful information about the word (Stahl & Nagy, 2006).Use cognate knowledge (Dressler, 2000).Teach word analysis and other word-learning skills.Engage students in learning words through talking about, comparing, analyzing, and using target words.

Vocabulary and Comprehension: Upper Elementary Grades
Native English speakers often depend on background knowledge and inferential skills when reading text.
ELLs seem to rely more on their vocabulary knowledge when reading the same texts.

Vocabulary Instruction to Support Text Comprehension
ELLs’ reading comprehension can be improved with targeted vocabulary intervention (Carlo et al., 2004).
Students may need long-term intervention for maximum impact and comprehension development (McLaughlin, August, & Snow, 2000).

Vocabulary and Comprehension
• Key components of instruction for ELLs:• Developing increased flexibility of English-language use• Learning words (vocabulary) in context• Distinguishing between important and unimportant text details and events• Responding orally to texts in increasingly skillful ways• Participating in student conversations related to text

Vocabulary-Building Instructional Strategies
High frequency English wordsGeneral purpose academic wordsContent-area vocabularyEnglish-Spanish cognates (for Spanish-speaking ELLs)Words conveying key conceptsHigh-utility wordsRelevant to content under studyWords that are meaningful to students

Dimensions of LanguageoConversational languageoUsed daily to communicate with othersoBasic Interpersonal Communicative Skills (BICS) (Cummins, 1979)oAcademic languageoThe language of text and content areasoCognitive Academic Language Proficiency (CALP) (Cummins, 1979)

Use of Academic Language
To participate fully in the classroom and learn new content, ELLs must be able to
Use and understand academic language in its various forms, for a variety of purposes;Learn new words (vocabulary) in context;Determine the difference between relevant and less relevant text in a given passage and the necessity of a specific reading and/or language task; and Participate in student conversations related to text.
Funded by U.S. Department of Education
Academic Language and School Success
Students need Basic Interpersonal Communication Skills (BICS).However, good conversational skills may be accompanied by poor academic language skills.Therefore, students need to develop Cognitive Academic Language Proficiency (CALP) to deal with academic content (Cummins, 1994).
Funded by U.S. Department of Education
Students Need Academic Language
to understand teacher explanations, to discuss what is being learned, to read for different purposes, and to write about their learning.
Funded by U.S. Department of Education
Academic Language:
Is difficult for non-native speakers and many native speakers who are struggling readers;
Uses and requires comprehension of a variety of language forms for a variety of purposes; and
Incorporates multiple language structures.
Funded by U.S. Department of Education
What Constitutes Academic Language?Vocabulary knowledge
Breadth: knowing the meanings of many words, including multiple words for the same, or related, conceptsDepth: knowing multiple meanings, both common and uncommon, for a given word
Understanding complex sentence structures and syntaxRecognizing written vocabulary as distinct from oral vocabularyUnderstanding the structure of argument, academic discourse, and expository texts

Role of Vocabulary in Academic Language Development
•Classroom and content vocabulary in academic texts differ from conversational vocabulary.•Academic vocabulary is critical to learning higher-level content and to performing well on achievement tests.•Academic language: explains, informs, justifies, compares, describes, classifies, proves, debates, persuades, evaluates.

Creative Methods to Develop and Reinforce Word Meanings
Scripted books purposefully crafted to reinforce word meaningGames for partner practice using picture cardsGames that give students incentives to listen for new words or previously taught words outside the vocabulary lesson

Academic LiteracyIs the reading proficiency required to construct the meaning of content-area texts and literature encountered in school.Encompasses the kind of reading proficiencies typically assessed on state-level accountability measures, such as the ability to
make inferences from textlearn new vocabulary from contextlink ideas across texts identify and summarize the most important ideas or content within a text

Cognitive Academic Language Learning Approach (CALLA)
Designed to increase ELLs’ achievement (Chamot & O’Malley, 1996)Integrates: content-area instruction, language development, explicit instruction in learning strategies:
Valuing prior knowledgeLearning important content and language skillsDeveloping language awareness and critical literacyUsing appropriate learning strategiesLearning to work with others in social contextLearning through hands-on, inquiry-based and cooperative skillsIncreasing motivationSelf-assessing learning

Collaborative Strategic Reading (CSR)
•Combines reading comprehension strategy and cooperative learning.•Is effective in culturally and linguistically diverse classrooms with struggling readers, ELLs, students with learning disabilities, average, and high-achieving students. •Students work in small heterogeneous groups .
Funded by U.S. Department of Education
CSR (cont.)Cooperative groups use 4 reading strategies:
Preview (activate prior knowledge)Click and chunk (monitor comprehension during reading, use strategies to understand)Get the gist (during reading, restate main idea of paragraph or section)Wrap-up (after reading, summarize new information, generate questions)
CSR (cont.)
Peer interaction provides opportunities to use academic language in meaningful communication about academic content (Cazden, 1998; Richard-Amato & Snow, 1992).
Teacher acts as a facilitator.

CSRBEFORE
READING
1. Preview• Brainstorm:
What do you know about the topic?
• Predict: What do you think you will learn?
AFTER READING
4. Wrap-Up• Ask questions
to check understanding
• Review
DURING READING
2. Click and chunk• Find hard-to-
understand words or word parts (chunk)
• Use strategies to fix chunks.
3. Get the gist• Find the most
important person place or thing
• Identify its importance

Sheltered Instruction Model (SI)
•A research-based approach to sheltered lesson planning and implementation•Demonstrated success in improving ELLs’ outcomes•Uses high quality strategies to develop ELLs’ academic English skills while learning grade-level content•Effective for all grade levels across the content areas
Narrowing theLanguage Gap:The Case for ExplicitVocabulary Instruction
byKate Kinsella
What Doesn’t WorkLooking up words in the dictionary
Using written context to figure out word meanings
Unplanned, extemporaneous vocabulary teaching.
What does work?Comprehensive vocabulary development
Students learned more through targeted vocabulary instruction
Learning through independent reading often led only to superficial understanding
Instructional steps•Pronounce•Explain•Provide examples•Elaborate•Assess
Vocabulary Teaching StrategyTeach a manageable amount (3-4) of critical words from a particular sectionDistribute a vocabulary note-taking guidePrompt students to assume an active rolePartner students for focused interaction during instructional process.Students take brief notes filling in omitted content as you provide essential information both verbally and in writing (e.g. on the overhead).Present the word in writing (on the board, overhead, computer).Pronounce the word; have students read and pronounce several times.
Vocabulary Teaching StrategyClarify the part of speech; whether it is a high-use word/lesson concept, etc.Provide a synonym (if any) using familiar language. Provide two concrete examples to create mental anchors.Actively engage students by assigning a brief partner application task.Provide a sentence starter to frame their oral responses grammatically and syntactically. Assign a brief writing task to guide students in applying word knowledge to a new context.

Vocabulary Study Strategies:
1. Read, Cover, Recite, Check
2. Vocabulary Study Cards3. Vocabulary Notebooks
(see Handout)
Teaching Words that Matter:
1. Big idea words: related to central concepts
2. High-use, widely applicable “academic tool kit” words
3. High-use “disciplinary tool kit” words4. Polysemous: multiple meaning, e.g. wave5. Academic words that students need to
know to engage in academic discourse
“We must keep in mind, however, that teaching vocabulary robustly is not an end in itself, but only a means to an end. The critical outcome is how well we equip students to thrive in academic contexts.” --Kate Kinsella
