Writing: Short and Extended Constructed Response
Writing: Short and Extended Constructed Response
The Writing domain asks you to explain your thinking in your own words. A short constructed response (SCR) is one focused paragraph that answers a question with text evidence. An extended constructed response (ECR) is a multi-paragraph essay that uses sources to support a claim. Grade 4 responses are scored for a clear idea, relevant evidence, explanation, organization, and grade-level conventions.
Core rules and concepts
- SCR: answer directly, give two relevant details, and explain each detail. Use the words of the question in your answer.
- ECR: open with a claim, organize body paragraphs by reason, cite evidence from each source, and close by restating the claim with a final insight.
- Elaboration means explaining how the evidence proves the claim. Do not stop at a quotation.
- Use linking words such as because, therefore, another reason, and this shows that.
- Name the source when you use it, for example: In 'Saving the Bees,' the author explains...
Worked example
Prompt: Should schools start later? Use both sources. Claim: Later start times help students do better in school. Body reason 1: More sleep improves attention. Evidence from Source 1: students got 35 more minutes of sleep. Explanation: extra sleep can help students focus in morning classes. Body reason 2: Later starts improve attendance. Evidence from Source 2: morning tardiness dropped. Explanation: fewer students arrive late, so they miss less instruction. Conclusion: A later start could help students learn, but schools must plan transportation. Reasoning: Each paragraph has one reason, one source detail, and an explanation that connects the detail to the claim.
Traps that cost marks
- Retelling the source instead of answering the prompt.
- Dropping in a quotation with no explanation.
- Using evidence from only one source when the prompt says both.
- Writing an introduction that never states a claim.
- Forgetting capital letters, end punctuation, or quotation marks around exact words.
