The document discusses several key aspects of teaching vocabulary to young language learners:
1. Both formal instruction of word meanings and informal exposure to words through activities are important. Young learners need repetition to acquire vocabulary over time.
2. A variety of word types should be taught, including nouns, verbs, adjectives, and others. Useful words are high frequency words learners will encounter.
3. Both direct instruction of word meanings and indirect teaching of strategies to determine meanings are effective approaches. Young learners need opportunities to use new vocabulary in context.
