They may need to learn the meanings of the Tier 1 words in a passage.
To select the best vocabulary words to teach before reading a text, the teacher should prioritize
which types of words?
words that are central to understanding key meanings in the passage
A primary-grade teacher who wants to implement research-based vocabulary instruction should
try to emphasize:
word relationships, including antonyms, synonyms, categories, and semantic families.
Good readers will stop and reread a portion of the text for clarification if they don’t understand
it. This behavior demonstrates:
cognitive flexibility and metacognition.
