How can a teacher support word learning across subjects?

• A. Explicitly teach tier-two vocabulary, provide multiple exposures, and connect words to concepts.
• B. Focus on phonics and decoding for all new words.
• C. Use only occasional word glossaries.
• D. Let students discover words through reading alone.

Answer: (A)

Supporting word learning across subjects hinges on explicit teaching of tier-two vocabulary, providing multiple exposures, and connecting words to concepts. Tier-two words are high-utility academic terms that students encounter across different subjects, and teaching them explicitly helps students grasp precise meanings that aren’t obvious from everyday language. Giving multiple exposures—through speaking, listening, reading, and writing in varied contexts—strengthens memory and the ability to retrieve and use these terms in new situations. Connecting words to concepts helps students see how terms fit into ideas, processes, and categories in math, science, social studies, and language arts, so vocabulary becomes a tool for understanding content, not just vocabulary to memorize. Relying only on decoding or phonics glosses over meaning, and expecting students to discover terms in isolation often leaves gaps. In practice, models, student-friendly definitions, examples and non-examples, visuals, and repeated usage across lessons help students build durable, transferable vocabulary knowledge.
