Closing the Vocabulary Gap

1. The vocabulary gap significantly impacts academic success and future opportunities

For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.

The Matthew Effect describes how the vocabulary gap widens over time, with word-rich students getting richer and word-poor students falling further behind. This gap begins early, with research showing that by age 3, children from professional families hear 32 million more words than those from disadvantaged backgrounds. This early disparity has far-reaching consequences:

• Academic achievement: Vocabulary size at 25 months predicts linguistic and cognitive skills at age 8
• Reading comprehension: Vocabulary at the end of first grade significantly predicts reading comprehension 10 years later
• Long-term outcomes: Children with restricted vocabularies at age 5 are more likely to be poor readers as adults, experience higher unemployment rates, and have more mental health issues

To address this gap, schools must focus on explicit vocabulary instruction, starting in early years and continuing throughout a child's education. This involves teaching both Tier 2 (academic) and Tier 3 (subject-specific) words, as well as fostering a love for language and reading.

2. Academic vocabulary is distinct from everyday language and requires explicit teaching

The limits of their vocabulary really do prove the limits of their world.

Academic language is characterized by complexity, abstraction, and information density. It differs significantly from everyday talk in several ways:

• Higher proportion of Latin and Greek vocabulary
• More complex words with challenging spellings
• Greater use of nominalizations (verbs or adjectives turned into nouns)
• Higher degree of abstraction and technical terminology

To help students access this language, teachers should:

1. Model the academic code in their own speech
2. Explicitly teach Tier 2 and Tier 3 vocabulary
3. Provide multiple exposures to new words in various contexts
4. Use graphic organizers to visualize word relationships
5. Encourage students to use academic language in their own speaking and writing

By making the implicit academic code explicit, teachers can empower all students to participate fully in their education and future careers.

3. Etymology and morphology are powerful tools for expanding vocabulary

I find it hard to resist the conclusion that, if children were introduced to some basic etymology, many of the 'famous' spelling errors would be avoided.

Word roots and parts provide a systematic way to understand and remember new vocabulary. By teaching students about common Latin and Greek roots, prefixes, and suffixes, teachers can help them:

• Decode unfamiliar words by recognizing familiar parts
• Understand nuanced meanings and relationships between words
• Improve spelling by recognizing patterns and origins
• Develop a curiosity about language that supports lifelong learning

Key strategies for teaching etymology and morphology:

• Introduce common word roots (e.g., 'bio', 'graph', 'phon')
• Explore word families and related words
• Use word part matching activities
• Create word trees or maps to visualize relationships
• Encourage students to become "word detectives"

This approach not only expands vocabulary but also deepens students' understanding of language and supports their learning across all subject areas.

4. Reading, academic talk, and word play are essential for vocabulary development

Just as developing a reading culture requires nurturing, with systematic planning and a shared sense of purpose, so does creating a culture of academic talk.

A multi-faceted approach to vocabulary development combines extensive reading, rich academic discourse, and engaging word play. To create word-rich classrooms:

1. Foster a culture of reading:

   • Ensure easy access to diverse, high-quality texts
   • Model reading for pleasure and purpose
   • Implement reading challenges and book clubs
   • Use read-alouds to expose students to complex texts

2. Promote academic talk:

   • Model sophisticated language use
   • Scaffold academic discussions using sentence starters and discourse markers
   • Implement strategies like "Talk like an expert" and "ABC feedback"
   • Provide ample wait time for students to formulate responses

3. Engage in word play:

   • Explore figurative language, idioms, and wordplay
   • Use games and activities to make vocabulary learning fun
   • Encourage students to create their own word jokes and puns

By integrating these approaches, teachers can create a rich linguistic environment that supports vocabulary growth and deepens students' engagement with language.

5. Disciplinary literacy recognizes subject-specific language demands

Every teacher is a teacher of reading and every teacher is a teacher of academic vocabulary. They are the most vital tools for learning that our children possess.

Subject-specific approaches to vocabulary and literacy are essential because each discipline has its own unique language demands. Disciplinary literacy involves:

• Understanding the specific vocabulary and text structures of each subject
• Recognizing how experts in the field read, write, and communicate
• Adapting general literacy strategies to suit specific subject needs

Examples of disciplinary literacy approaches:

• Science: Focus on precise terminology, symbolic representations, and causal language
• History: Emphasize chronological terms, source analysis vocabulary, and interpretive language
• Mathematics: Highlight technical terms, symbolic notation, and logical connectors

To implement disciplinary literacy:

1. Identify key vocabulary and language structures in your subject
2. Explicitly teach subject-specific reading and writing strategies
3. Model expert thinking and communication in your field
4. Collaborate with colleagues to develop consistent approaches across subjects

By recognizing the unique language demands of each subject, teachers can better support students in developing the specific literacy skills needed for success in all areas of the curriculum.

6. Effective spelling instruction goes beyond rote memorization

Spelling isn't incidental, it is deeply meaningful and offers children powerful knowledge.

Spelling by reason, rather than rote, involves teaching students to understand the patterns and logic behind English orthography. This approach:

• Draws on etymology and morphology to explain spelling patterns
• Teaches common roots, prefixes, and suffixes
• Explores the historical reasons for spelling anomalies
• Focuses on high-frequency words and academically useful vocabulary

Strategies for effective spelling instruction:

1. Teach common spelling patterns and rules, but acknowledge exceptions
2. Use word sorts to help students recognize patterns
3. Explore word origins and related word families
4. Practice identifying and using morphemes (prefixes, roots, suffixes)
5. Implement regular, low-stakes spelling practice with immediate feedback
6. Encourage students to develop personal spelling strategies

By moving beyond weekly spelling tests and rote memorization, teachers can help students develop a deeper understanding of English orthography and become more confident, accurate spellers.

7. Closing the vocabulary gap requires a whole-school approach and ongoing assessment

We need to reduce how much time teachers spend marking errors in books and increase the time spent on teaching words, their meaning and related spelling patterns.

A systematic approach to vocabulary development involves coordinated efforts across all subjects and grade levels. Key components of a whole-school strategy include:

1. Professional development for all teachers on vocabulary instruction
2. Consistent approaches to teaching and assessing vocabulary across subjects
3. A school-wide focus on academic language and disciplinary literacy
4. Regular assessment and monitoring of students' vocabulary growth
5. Involvement of parents and the wider community in supporting vocabulary development

Effective assessment strategies:

• Use pre- and post-assessments to measure vocabulary growth
• Implement formative assessment techniques like exit tickets and quick writes
• Utilize standardized assessments to track long-term progress
• Encourage student self-assessment and reflection on vocabulary learning

By making vocabulary development a school-wide priority and implementing ongoing assessment, schools can create a culture that values and supports language growth for all students, helping to close the vocabulary gap and improve academic outcomes.
