Understanding ELL Metrics

Long Sentences: 25+ words; longer sentences impose greater cognitive load, especially with embedded clauses.

Complex Words: 3+ syllables; multisyllabic words are harder to decode and often carry academic or domain-specific meaning.

Academic Vocabulary: Words from the Academic Word List (AWL) — high-utility cross-disciplinary words rarely used in everyday conversation.

Passive Voice: Subject receives the action (e.g., "was discovered"); obscures the agent and is a common source of EL confusion.

High-Frequency Coverage: Percentage of text from the most common English words. Higher = more accessible without specialized vocabulary.

Cognates Found: Words similar in English and the selected language(s) sharing the same meaning — a powerful bridge for students whose L1 shares roots with English.
