Why It Matters
Academic vocabulary (Tier 2 words like 'analyze', 'contrast', 'significant') is the language of learning itself. A student who does not know what 'evidence' means cannot follow an instruction to 'support your answer with evidence'. Research by Averil Coxhead identified 570 word families (the Academic Word List) that account for about 10% of academic text. Explicit instruction in these words significantly improves academic reading comprehension.
Frequently Asked Questions
- What makes vocabulary 'academic'?
- Academic vocabulary (Tier 2) consists of words that appear frequently across school subjects but are rarely used in casual conversation. Words like 'analyze', 'interpret', 'significant', and 'justify' are essential for understanding instructions, textbooks, and assessments.
- How is this different from regular vocabulary?
- Tier 1 words (everyday words like 'dog', 'run') are learned naturally. Tier 3 words (technical terms like 'photosynthesis') are subject-specific. Tier 2 academic words fall between — they cross all subjects and require explicit instruction.
- How many academic words should I know?
- The Academic Word List contains 570 word families. Students who master these words can understand approximately 10% more of any academic text, which significantly improves comprehension across all subjects.
