The document discusses vocabulary instruction standards and choosing words to teach. It explains that there are three tiers of words: Tier 1 are basic words, Tier 2 are more sophisticated words used across disciplines, and Tier 3 are domain-specific. Participants will learn to identify Tier 2 words and determine which to teach using criteria like how often students will see the word and if its meaning can be inferred from context. The goal is for students to deeply understand words and use them independently in various contexts.
