How should Tier 2 vocabulary be taught under Standard 1?

• A. Explicit, depth-focused instruction across contexts and morphological analysis, with multiple encounters in various contexts, teach morphological analysis, and connect vocabulary to comprehension.
• B. Memorize lists only.
• C. Teach only Tier 3 words.
• D. Avoid teaching Tier 2 words altogether.

Answer: (A)

Tier 2 words are the high-utility academic terms students will encounter across many subjects, and they influence comprehension when students learn them deeply. The best approach is explicit, depth-focused instruction that clearly defines each word, models how to use it, and provides practice in multiple contexts. Students should encounter the word repeatedly in different texts and tasks, not just once, so they can see how the word fits in varied ideas and situations. Teaching morphology—examining roots, prefixes, and suffixes—helps students infer meanings and see connections between words, which strengthens their ability to uncover unfamiliar terms independently. Embedding these words in purposeful reading and discussion, and guiding students to use them in paraphrase, sentence construction, and explanation, turns vocabulary knowledge into comprehension power.

Memorizing lists alone gives only a snapshot of meaning and doesn’t support applying the word in new contexts. Focusing only on Tier 3 words misses the broad, transferable utility of Tier 2 terms encountered across domains. And avoiding Tier 2 words altogether would leave gaps in students’ ability to understand text across subjects.
