Informational Text and Author's Purpose
Grade 9 · English · Study Guide
Learn to read nonfiction strategically — identifying what an author is doing, why they are doing it, and how they use evidence and structure to achieve their goals.
Informational texts include everything from news articles and textbooks to speeches, memoirs, and scientific reports. Reading them effectively requires a different strategy than reading fiction. You must constantly ask: What is the author's purpose? What claim are they making? What evidence do they use? And what might they be leaving out?
Author's purpose is often summarized as PIE: Persuade, Inform, or Entertain. Most informational texts do more than one of these simultaneously — a memoir can inform AND entertain AND persuade. Identifying the primary purpose helps you understand which reading strategies to apply. A persuasive text requires you to evaluate evidence and spot bias. An informational text requires you to distinguish fact from opinion and identify the author's credentials.
Text structure is another key tool. Informational writers organize their ideas using recognizable patterns: cause-and-effect (this happened because of that), compare-and-contrast (A versus B), problem-solution (here is the issue; here is the fix), chronological order (events in time sequence), and description (detailed explanation of a topic). Recognizing text structure helps you predict where information will be placed and how the author's ideas relate to each other — making you a dramatically faster, more effective reader.
| Structure | Signal Words | Use Case |
|---|---|---|
| Cause and Effect | because, as a result, therefore, consequently | Explaining why something happened |
| Compare and Contrast | however, similarly, on the other hand, unlike | Examining two or more subjects |
| Problem and Solution | the problem is, one solution, as a result | Proposing fixes to an issue |
| Chronological Order | first, then, next, finally, in 1865 | History, biography, process |
| Description | for example, specifically, such as, including | Explaining features of a topic |

Practice questions
What does the PIE framework stand for in analyzing author's purpose?
- Point, Idea, Evidence
- Persuade, Inform, Entertain
- Preview, Interpret, Evaluate
- Position, Intent, Evidence
Show answer
Answer: Persuade, Inform, Entertain
PIE is a foundational framework for author's purpose analysis. Identifying which purpose dominates — or how they blend — guides your critical reading strategy.
An author who presents only evidence supporting one side of an argument is demonstrating:
- Central Idea
- Text Structure
- Bias
- Synthesis
Show answer
Answer: Bias
Bias occurs when an author presents information in a way that unfairly favors one position — through selective evidence, omission, loaded language, or misrepresentation of the opposing view.
A fact is a statement that can be verified, while an opinion expresses a belief or judgment.
Show answer
Answer: True
This is a foundational distinction in critical reading. Facts (verified data) vs. opinions (judgments and beliefs) — blurring this line is how misinformation spreads.
Signal words like 'because,' 'as a result,' and 'therefore' indicate a ___ text structure.
Show answer
Answer: cause and effect
Cause-and-effect signal words trace relationships: because (cause), therefore/as a result (effect). Recognizing them helps you map the logical chain in an argument.
Identifying an informational text's structure before reading helps with comprehension and retention.
Show answer
Answer: True
Research supports this: activating your knowledge of text structure (how information is organized) before reading primes your brain to process and retain information more efficiently.
Fun facts
- The average American adult reads at a 7th-8th grade level, which is why most newspapers and popular nonfiction aim for that range.
- Scientific studies show that readers who identify text structure before reading retain 40% more information than those who read without that framework.
