Vocabulary and Comprehension
Vocabulary and Comprehension (Domain 3)
This domain tests meaning-making: how readers acquire words and how they construct understanding from narrative and expository text. Questions often ask you to select the most effective vocabulary routine or comprehension strategy for a described student.
Core rules
- Vocabulary tiers: Tier 1 words are common oral words; Tier 2 words are high-frequency, cross-domain academic words that mature readers need (for example, contrast, reluctant); Tier 3 words are domain-specific (photosynthesis, legislature). Prioritize Tier 2 for direct instruction.
- Effective vocabulary instruction is explicit, provides student-friendly definitions, examples and non-examples, multiple exposures in reading and discussion, and opportunities for active use. Morphology and context clues support independent word learning.
- Comprehension depends on background knowledge, vocabulary, syntax, verbal reasoning, and text structure. Narrative text follows story grammar; expository text uses compare-contrast, cause-effect, problem-solution, sequence, and description.
- Teach strategies through gradual release: modeling, guided practice, independent application. Useful strategies include predicting, questioning, monitoring, visualizing, inferring, determining main idea, and summarizing.
- QAR distinguishes Right There, Think and Search, Author and Me, and On My Own. It helps students see that some answers require inference and background knowledge.
- Before/during/after reading routines build purpose, active processing, and reflection.
Worked example
A teacher plans to teach the word reluctant before a story about a dog that hides when the vacuum starts. She gives the definition “not wanting to do something,” contrasts it with eager, asks students to show reluctant body language, and returns to the word when the dog refuses to come out. Reasoning: reluctant is Tier 2, likely to appear across texts, and the story context supports meaning. A copied dictionary definition alone would not build usable depth.
Traps
- Treating all unknown words as Tier 3 and teaching long lists of rare terms.
- Relying on dictionary copying rather than explanation, examples, and use.
- Teaching strategies as isolated worksheets instead of tools for understanding text.
- Asking only literal questions and never modeling inference.
- Neglecting background knowledge, then expecting comprehension from decoding alone.
