Building Vocabulary: Practical, Evidence-Informed Strategies (Updated 2025)
Why vocabulary matters (with evidence)
- Vocabulary is a key driver of reading comprehension and access to the wider curriculum. Pupils with broader vocabularies understand more, learn faster from text, and write with greater precision.
- Explicit vocabulary instruction has positive effects on comprehension when it includes rich explanations, multiple encounters, and active use (Stahl & Fairbanks; EEF).
- Background knowledge and vocabulary develop together; knowledge-rich, well-sequenced curricula accelerate word learning (DfE Reading Framework; EEF).
Foundations and frameworks
- Beck’s Tiers: focus explicit teaching on Tier 2 words (general academic words) while building Tier 3 (subject-specific) in context.
- Graves’ four-part framework: wide reading and rich language experiences; explicit teaching of words; word-learning strategies (morphology/context); word consciousness.
- Morphology matters: teach prefixes, suffixes, and roots (Latin/Greek) to support decoding, meaning, and transfer (Goodwin & Ahn; Bowers, Kirby & Deacon).
Selecting words to teach
- Teach 6–10 Tier 2 words per text/week in KS2 (fewer in KS1), chosen for utility, frequency across subjects, and conceptual importance.
- Prioritise teachable concepts, not just hard words. Choose words that unlock a text or topic and appear again across the curriculum.
- Plan for revisiting: schedule retrieval after 1, 3–7, and ~30 days; recycle words in talk and writing.
Robust vocabulary routine (SEEC)
- Select: Pick high-utility words that unlock the text/topic (Tier 2/3).
- Explain: Give a child-friendly definition and pronunciation; connect to known concepts.
- Examples/Non-examples: Provide multiple, varied contexts; contrast close confusions; use images/realia when helpful.
- Consolidate: Oral rehearsal, sentence frames, quick-writes, retrieval quizzes, and application in subject work. Spaced practice across weeks.
Morphology: weekly habits
- Teach common prefixes/suffixes early (un-, re-, pre-, -ful, -less, -ment, -tion) and build to Latin/Greek roots (tele, photo, geo, struct).
- Word sums and matrices: e.g., struct + ure → structure; re + struct + ion → re-struct-ion. Explore meaning shifts with affixes.
- Morphology in subjects: decompose technical terms (photosynthesis, democracy) to make meanings transparent and memorable.
Classroom practices that work
- Dialogic read-alouds and structured talk: ask purposeful questions; require evidence and elaboration; recycle target words in discussion.
- Knowledge-first sequencing: pre-teach a small set of words and key knowledge before reading to boost access and confidence.
- Graphic organisers: Frayer models, concept maps, and semantic gradients to deepen meaning and relationships among words.
- Reading for pleasure: daily read-alouds, curated libraries, pupil choice, and reading communities increase incidental vocabulary growth.
- Interleaving and retrieval: short, low-stakes quizzes; cumulative review; mix old and new words; quick sorting/matching tasks.
Phase guidance: EYFS, KS1, KS2, and bridge to KS3
- EYFS: oral language first — songs, rhymes, story talk, role play; introduce 3–5 words per week tied to themes with visuals/realia.
- KS1: link words to phonics/graphemes; short, lively teaching with pictures/actions; word walls and sentence stems for use in writing.
- KS2: weekly Tier 2 sets (6–10 words), morphology mini-lessons, text-structure knowledge; reciprocal teaching routines for comprehension.
- KS3 bridge: disciplinary literacy — teach how vocabulary works differently in science vs. history; explicit morphology/etymology of technical terms; insist on precise use in explanations and arguments.
EAL and language needs
- Pre-teach words with visuals, bilingual glossaries, and realia; use gestures and actions to cement meaning.
- Maintain and value first language; use cognates and morphology links where appropriate.
- Short, frequent oral rehearsal; sentence frames; partner talk; corrective feedback via recasting and extension.
Assessment and progress monitoring
- Entry checks: quick explain-it-back prompts; multiple choice with plausible distractors; sentence completion.
- Application: use in oral/written sentences; short writing that requires target words in context (with success criteria).
- Cumulative quizzes and concept maps: look for precision, examples, non-examples, and connections.
- Work scrutiny: check for accurate, confident use over time across subjects; track class and subgroup progress (EAL/SEND/FSM).
Home–school partnership
- Weekly family word cards with images and prompts for talk; short scripts for discussing words at home.
- Library memberships, book swaps, and author events; encourage reading for pleasure and shared reading.
- Share 60-second videos modelling how to teach a new word and revisit it across the week.
Implementation playbook (first 30 days)
- Week 1: Audit current practice against DfE Reading Framework and EEF guidance. Identify 8–10 recurring Tier 2 words per subject for the next unit.
- Week 1: Build a vocabulary spine by year group (EYFS–KS2) including morphology map (prefixes/suffixes/roots) and a read-aloud spine.
- Week 2: CPD on SEEC routine, morphology, and dialogic reading. Create shared, child-friendly definitions and exemplar sentences.
- Week 2: Launch 10-minute daily routines: quick review, one new word, oral rehearsal, and application in exit tickets.
- Week 3: Introduce retrieval schedule (1, 3–7, ~30 days). Start word walls/knowledge organisers and cumulative quizzes.
- Week 4: Review samples and short checks; refine selection; plan the next 6 weeks; share with families.
Technology: helpful, with guardrails
- Use spaced-retrieval apps (e.g., digital flashcards) to schedule reviews; ensure teacher-curated definitions and examples.
- Use image/audio supports for EAL and SEND; avoid over-reliance on auto-generated definitions without teacher oversight.
- AI supports can suggest example sentences and quiz items; teachers should check for accuracy and age-appropriateness.
