Fourth-Grade Expository Text and Cause-Effect
Mr. Chen’s fourth-grade class has 24 students, including 8 English learners. During a social studies unit on the causes of the American Revolution, students read a two-page chapter. Most read orally at about 110–120 words per minute with few errors. On an eight-item quiz, 12 of 24 scored below 50%, and their wrong answers were mostly literal facts out of order, not main-idea statements. In discussion, several students can name events such as the Stamp Act and Boston Tea Party but cannot explain how one led to another. Mr. Chen has five 45-minute periods before the unit test. The district requires coverage of the chapter’s content and a short constructed response. He is considering adding more quizzes or reteaching the chapter aloud. The English learners include students at intermediate English proficiency who can decode English but lack academic vocabulary such as “tax,” “boycott,” and “representation.”
1. Diagnose the likely cause of the comprehension problem and decide whether to focus on word reading, comprehension strategy, or knowledge building.

The pattern points to comprehension and knowledge, not word reading: 110–120 words per minute with few errors is adequate for Grade 4, and literal questions are answered, but students list facts and cannot explain causation. The wrong answers being facts out of order suggest they are not building a mental model of cause and effect. The English learners' missing academic vocabulary further limits this. Therefore, do not add more quizzes or simply reread aloud. Prioritize background knowledge and text structure: cause-effect signal words, a timeline, and a graphic organizer. Model think-alouds that connect events. This is a judgment call because fluency can mask comprehension problems; the data show the bottleneck is meaning-making, not decoding.
2. Design a two-day instructional sequence that addresses the problem while still covering content.

Day 1: build knowledge with a short video or images of tax policies, then preteach six to eight words (tax, boycott, representation, repeal, protest, liberty) with student-friendly definitions and a sentence frame. Read the first half aloud or with partners; students complete a cause-effect chart with “because” and “as a result.” Day 2: model a main-idea paragraph using the chart, then students write a two-sentence summary with a frame: “The colonists reacted to ___ by ___, which led to ___.” English learners get a word bank and paired reading with a bilingual glossary if available. This sequence uses gradual release, keeps content coverage, and makes the causal structure visible instead of quizzing students on facts they can already recall.
3. How should Mr. Chen assess main idea and causation, and how should he use English learner data?
Read the worked answer
Assess with a constructed response that requires causation and a main idea, not only matching. Use a short new paragraph and ask for one cause, one effect, and the main idea, scored with a three-point rubric: accurate cause, accurate effect, and a sentence that subsumes both. Compare English learners' scores on the same task with and without the word bank to see whether vocabulary is the barrier. If they can identify causation orally but not in writing, the issue is production, not comprehension. This informs next steps and avoids confusing language proficiency with a reading disability.
