Comprehension: Vocabulary, Knowledge, and Strategy
What the domain asks
Comprehension items test your grasp of the knowledge and strategies a reader brings to text. Vocabulary is the bridge: Tier 1 words are everyday, Tier 2 words are high-utility academic words worth direct teaching, and Tier 3 words are domain-specific. Teach vocabulary directly (student-friendly definitions, examples and non-examples, multiple exposures, morphology, context) and incidentally through wide reading.
Strategy instruction-predicting, questioning, monitoring, inferring, summarizing, using text structure and graphic organizers-works when it is modeled, practiced toward automaticity, and then used as a tool for content rather than as the content itself. Background knowledge drives inference. Narrative text calls for story elements and retelling; expository text calls for its structures (description, sequence, compare-contrast, cause-effect, problem-solution). Discussion and writing about reading consolidate understanding.
Traps
- Teaching strategies as ends rather than means; strategy drilling without knowledge-building produces flat growth.
- Confusing topic (a word or phrase), main idea (a sentence-level gist), and theme (a universal message).
- Confusing literal recall with inference; inference combines text evidence with background knowledge.
- Assuming leveled text with heavy picture support builds comprehension; scaffolds must be withdrawn.
- Calling any unfamiliar word "Tier 3."
Rule of thumb
For any comprehension question, name the cognitive demand first. If the answer is stated in the text, it is literal; if the reader must connect two sentences, it is an inference; if it requires judging author's purpose or character motive, it is analysis. Then choose the scaffold that matches that demand-rereading, a text-dependent question, a sentence frame, or a graphic organizer.
