Previewing Text — I can preview a text (title, headings) to...

SECTION 1

Historical Context & Motivation

A long time ago, books did not have titles, headings, or chapter names. Readers had to start at the first word and read straight through to the end. Today, most texts have helpful parts like titles and headings. These parts help readers know what a text is about before they even start reading.

Learning to use these parts before you read is called previewing. Good readers preview a text first. They look at the title and headings to get ready to read. This lesson will teach you how to preview so that reading becomes easier and clearer.

Long Ago

Books Without Headings

Old books were often written as one long block of text, with no titles, headings, or breaks to guide the reader.

1450s

The Printing Press

Printed books began to include titles, chapter names, and page numbers. This made it easier for readers to preview before reading.

Today

Reading on Screens

We now read on phones, computers, and paper. Good readers still scan titles and headings first, before reading the whole text.

The big question in this lesson is simple: How can you figure out what a text is about — before you even start reading it? The answer is to look closely at the title and headings first. That skill is called previewing, and it is what you will practice in this lesson.

SECTION 2

Core Principles of Previewing

Previewing is a pre-reading strategy — a few quick steps you take before you read a text from start to finish. When you preview, you connect new information to what you already know. This helps your brain understand and remember the text better. Previewing turns you into an active reader — someone who thinks about a text before, during, and after reading it.

Identify the Title

The title is the biggest clue about a text's topic. Read it and ask yourself: What is this text about?

Read the Headings & Subheadings

Headings break the text into parts. Reading them shows you the main ideas and the order they come in.

Notice Text Features

Bold words, pictures, and captions are text features. They point out important information before you read the paragraphs.

Predict the Topic

Use the title, headings, and features to make a prediction — a best guess about the topic. Your guess does not have to be perfect.

Predict the Purpose

Ask: Is this text trying to inform, persuade, entertain, or instruct? The title and headings often show the author's purpose.

✦ KEY TAKEAWAY

Previewing a text is like reading a menu before you order food. You would not ask the server to bring every dish so you could taste them all. Instead, you look at the menu sections, read the names, and check any pictures. In a few seconds, you know what the restaurant offers. Previewing a text works the same way — you scan the title, headings, and features to get a quick idea of what is inside before you read.

SECTION 3

Visual Explanation — Anatomy of a Text to Preview

The picture below shows a typical article and points out the parts you should look at when you preview. Each labeled part gives a clue about the topic and purpose. Notice that these parts look different from the body text, so you can find them quickly.

This diagram shows a sample article page with five key preview elements labeled: ① Title, ② Author/Source, ③ Headings, ④ Images & Captions, and ⑤ Bold Words. These are the elements you scan before reading the body text.

In the picture, the gray bars stand for body text. You do not read those during a preview. Instead, look at the title, then the author line, then each heading. Also glance at pictures and bold words. This whole preview should take less than a minute. It gives you a starting picture of what the text will say before you read it closely.

SECTION 4

Why Previewing Helps You

Why does previewing help you understand a text better? When you preview, your brain connects new information to what you already know. This makes new ideas easier to follow and remember. If you start reading without previewing, your brain has to work harder to make sense of new information.

The Three Steps of Reading

Good reading happens in three steps: before reading, during reading, and after reading. Previewing happens in the first step. Before you read, you look at the text and guess what it is about. While you read, you check whether your guess was right. After you read, you think back over what you learned. This cycle of guess → read → check helps you understand more.

The three-phase reading cycle shows that previewing (Phase 1) prepares your brain before you enter the during-reading phase (Phase 2), and the cycle completes with reflection (Phase 3).

Guesses Help — Even Wrong Ones

You might ask, "What if my guess is wrong?" That's okay! Making a guess — even a wrong one — helps you more than making no guess at all. When your guess turns out wrong, you notice the difference between what you expected and what you found. That difference makes you pay closer attention, and it helps you remember the text better. So do not worry about being exactly right. What matters is making a guess before you read.

SECTION 5

Types of Text Features

Different texts use different features. Knowing what to look for makes your previewing faster. The table below lists common text features and what each one tells you.

Common text features and what each one tells you during previewing

Text Feature	Where You Find It	What It Tells You
Title	Top of the text, in the biggest letters	The main topic of the whole text
Subtitle	Just below the title, in smaller letters	More details about the topic, or the author's angle
Headings / Subheadings	At the start of each part, in bold or a different style	The main idea of each part and the order of the parts
Bold or italic words	Inside the paragraphs	Important words or ideas
Images / Photographs	In or next to the text	A picture that shows the topic
Captions	Below or next to pictures and charts	A short sentence that explains the picture
Charts / Graphs / Tables	Inside the text, often in nonfiction	Numbers or facts that support the writer's ideas
Sidebars / Callout boxes	In the margin, set apart from the main text	Extra facts or definitions

Guessing Why the Text Was Written

Previewing also helps you guess the author's purpose — the reason the text was written. Most texts do one of four things: inform (give facts), persuade (try to convince you), entertain (tell a story or amuse), or instruct (teach you how to do something). A title like "10 Reasons to Eat More Vegetables" tries to persuade. A title like "The History of the Railroad" tries to inform. Headings with numbered steps ("Step 1," "Step 2") show the text will instruct. Noticing words like these during your preview helps you guess the purpose quickly.

💡 Tip: Ask Two Quick Questions

After you scan the title and headings, stop and ask yourself two questions: "What is this text about?" (topic guess) and "Why did the author write this?" (purpose guess). A short answer to each question is enough to get you ready to read.

SECTION 6

Worked Example — Previewing an Article

Let's practice previewing with a sample article. Imagine you are given this article to read for a health class. Before reading the body text, you will preview its features and make guesses about it.

📄 Sample Article Features

Title: "Drinking Water: How Much Is Enough?" Source: Healthy Living Magazine Heading 1: Why Water Matters Heading 2: Signs of Dehydration Heading 3: How Much Should You Drink Each Day? Image: A chart showing recommended daily water intake by age group Bold word spotted: dehydration

Previewing Step by Step

Step 1 — Read the TitleThe title is "Drinking Water: How Much Is Enough?" This tells us the text is about drinking water, and specifically about how much a person should drink. The question in the title tells us the article will try to answer it.

Topic guess: The text is about how much water people should drink.

Step 2 — Note the SourceThe source is "Healthy Living Magazine." This is a health magazine, so we can expect the article to give simple, easy-to-read health advice — not a hard science paper.

Clue: Expect simple, practical health advice.

Step 3 — Scan the HeadingsThe three headings are: "Why Water Matters," "Signs of Dehydration," and "How Much Should You Drink Each Day?" Reading them in order shows the plan of the article: first why water matters, then what happens if you don't drink enough, then how much you should drink. This order is common in informative texts.

Structure guess: Why it matters → Warning signs → How much to drink.

Step 4 — Notice Images and Bold WordsThe chart shows how much water people need by age. This tells us the article will give real numbers. The bold word "dehydration" is an important word the author wants you to notice — it connects to the second heading.

Clue: The article has numbers (a chart) and a key word (dehydration).

Step 5 — Form Your Final PredictionsNow we put all the clues together. The topic is water and health. The purpose is to inform readers about how much water to drink and what happens if they don't drink enough.

Final guess — Topic: daily water intake and dehydration. Purpose: to inform and advise.

We made these guesses without reading any of the body text. The whole preview took five short steps and less than a minute. Even if the article said something a little different than we expected — for example, if it also talked about drinking too much water — our preview still gave us a strong idea of what to expect.

SECTION 7

Benefits and Common Pitfalls of Previewing

Like any skill, previewing has clear benefits — and a few common mistakes to watch out for. Knowing both will help you use this skill well.

A comparison of the benefits of previewing and common mistakes to avoid

Benefits of Previewing	Common Pitfalls to Avoid
Connects new information to what you already know, so it sticks better	Spending too long previewing — it should be quick (30–60 seconds), not a full read
Helps you set a purpose for reading, which keeps you focused	Treating your guess as the final answer, instead of something you can change
Shows you the order of ideas, making the text easier to follow	Skipping the preview because a text "looks short" — even short texts benefit from a quick scan
Helps you notice new words before you meet them in a sentence	Only reading the title and skipping headings, pictures, and bold words
Makes hard texts feel less scary — you know what to expect	Thinking this only works for nonfiction — it works for stories too (chapter titles count)

✦ KEY TAKEAWAY

Previewing is like stretching before you exercise. You would not run at full speed without warming up your muscles first. In the same way, you should not jump into a hard text without warming up your brain. Stretching helps your body move well and lowers the risk of injury. Previewing helps your brain understand better and lowers the risk of confusion. The warm-up only takes a minute, but it makes a big difference.

SECTION 8

What Comes After Previewing

Previewing is a great first step, but it is not the only reading skill you will learn. As you keep practicing, you will learn other skills that build on previewing.

How previewing connects to other reading skills

Strategy	When It's Used	How It Builds on Previewing
Previewing	Before reading	The first step — scan titles and headings to guess topic and purpose
Questioning	Before and during reading	Turn your preview guesses into questions to look for answers to while reading
Annotating	During reading	Mark up the text with notes and underlines, often guided by your preview
Summarizing	After reading	Retell the main ideas in your own words — easier when you noticed the headings first
SQ3R Method	Full reading process	A five-step study method: Survey, Question, Read, Recite, Review. Previewing matches the Survey step.

The SQ3R method is a well-known study method with five steps: Survey, Question, Read, Recite, and Review. The first step, Survey, is the same as previewing. Because every step after it depends on a good survey, learning to preview well now will help you with every reading skill you learn later.

SECTION 9

Practice Problems

The following five problems will test your ability to preview text features and form predictions about topic and purpose. Each problem presents a set of text features — imagine these are all you can see before reading the full text. Use them to make your predictions.

PROBLEM 1 — CONCEPTUAL

An article has the title "The Life Cycle of a Butterfly." Based on the title alone, what is your prediction for the topic of this article? What is the likely purpose — to inform, persuade, entertain, or instruct?

PROBLEM 2 — BASIC

You see the following features: Title: "Save Money on Groceries This Month." Headings: "Make a List Before You Shop," "Use Coupons and Store Apps," "Buy in Bulk." What is the predicted topic? What is the predicted purpose? Explain how the headings helped you decide on the purpose.

PROBLEM 3 — INTERMEDIATE

An article has: Title: "Why Every School Should Teach Coding." Headings: "The Digital Skills Gap," "Success Stories from Coding Programs," "What Parents Can Do." There is also a bold word: "digital literacy." Predict the topic, purpose, and intended audience. Explain which text features gave you clues about the audience.

PROBLEM 4 — APPLIED

You are registering for community college classes online. You find a webpage with: Title: "Spring 2025 Course Registration Guide." Headings: "Important Dates and Deadlines," "How to Search for Classes," "Step-by-Step Registration Instructions," "Troubleshooting Common Errors." There is also an image of a screenshot of the registration portal. Using your previewing skills, predict the topic, purpose, and how you would use this text differently from an article you read for a class assignment.

PROBLEM 5 — CRITICAL THINKING

Consider two articles with similar titles: Article A — Title: "Coffee and Your Health"; Headings: "The Science Behind Caffeine," "Health Benefits of Moderate Use," "Risks of Overconsumption." Article B — Title: "Why You Should Quit Coffee Today"; Headings: "My Coffee Addiction Story," "What the Research Really Says," "A 30-Day Challenge for You." Both articles are about coffee and health, but they differ significantly. Using only the previewing features, compare and contrast the predicted purpose, tone, and structure of each article. How would your reading approach differ for each one?

SUMMARY

Lesson Summary

Previewing is a pre-reading strategy in which you scan a text's title, headings, bold words, images, and other text features before reading the body text. The goal is to connect new information to what you already know, so the text is easier to understand. By previewing, you make guesses about a text's topic (what it is about) and purpose (why it was written — to inform, persuade, entertain, or instruct).

Previewing is the first step of active reading: preview → read → reflect. It matches the Survey step of the SQ3R method. Even wrong guesses are helpful because they make you pay closer attention. The habit to build is this: before you read any text, spend 30 to 60 seconds scanning its title and headings, then ask two questions — "What is this text about?" and "Why was it written?" — to turn yourself into an active, strategic reader.
