About This Topic

Informational texts are the 'instruction manuals' for the world, and text features are the tools that help us navigate them. In this topic, students analyze how headings, subheadings, captions, sidebars, and graphics (like charts and maps) contribute to the clarity and efficiency of information. They learn that an author's choice of 'structure', whether chronological, cause/effect, or problem/solution, is a deliberate strategy to achieve a specific purpose.

This unit aligns with CCSS standards for analyzing in detail how an author's ideas or claims are developed and refined by particular sentences, paragraphs, or larger portions of a text. Mastering text features is a critical 'life skill' for college and career readiness. This topic is best taught through 'scavenger hunts' and 'design' challenges where students must use these features to make complex information accessible.

Key Questions

1. How do visual aids like charts support the central claim of a text?
2. Explain how headings and subheadings guide the reader through complex information.
3. Evaluate the effectiveness of different text features in enhancing reader comprehension.

Learning Objectives

• Analyze how specific headings and subheadings organize complex information in informational texts.
• Evaluate the effectiveness of visual aids, such as charts and graphs, in supporting an author's central claim.
• Compare the clarity and accessibility of information presented with and without effective text features.
• Create a short informational passage that effectively uses headings, subheadings, and at least one visual aid to enhance reader comprehension.

Before You Start

Identifying Main Idea and Supporting Details

Why: Students need to be able to find the central point of a text before they can analyze how text features help present it.

Understanding Different Text Structures

Why: Recognizing structures like compare/contrast or cause/effect helps students understand how headings and subheadings further organize this information.

Key Vocabulary

Heading	A title for a section of a text that indicates the main topic of that section.
Subheading	A secondary title that divides a section into smaller, more specific parts, providing further detail about the content.
Visual Aid	An image, chart, graph, map, or diagram used in a text to present information visually and aid understanding.
Central Claim	The main argument or point the author is trying to convey and support throughout the informational text.
Reader Comprehension	The ability of a reader to understand and interpret the meaning of a text.

Watch Out for These Misconceptions

Common Misconception

You can skip the 'pictures and captions' to save time.

What to Teach Instead

In informational texts, the graphics often contain the 'evidence' for the main claims. Use a 'Graphics Only' challenge where students have to answer questions using *only* the charts and captions to show how much information they provide.

Common Misconception

Headings are just 'titles' for paragraphs.

What to Teach Instead

Headings are 'signposts' that signal the logical progression of an argument. A 'Heading Shuffle' activity (where students have to match headings to paragraphs) helps them see that headings are part of the text's 'skeleton.'

Active Learning Ideas

Inquiry Circle: The 'Feature' Scavenger Hunt

Give groups a complex technical manual or a long scientific article. They must find and label five different text features and explain how each one 'saved them time' or 'clarified a confusing point.'

Role Play: The Information Designer

Students are given a 'wall of text' with no features. They must work in pairs to 'design' the page by adding three subheadings, one sidebar, and one 'captioned image' that would help a 6th grader understand the main points.

Think-Pair-Share: Structure Match-Up

Students are given three different 'topics' (e.g., 'The History of the Internet,' 'How to Fix a Bike,' 'Why Bees are Dying'). They pair up to decide which 'structure' (Chronological, Process, Cause/Effect) would be best for each and why.

Real-World Connections

• Journalists and editors use headings, subheadings, and graphics to structure news articles, making complex events understandable for a broad audience. For example, a feature on climate change might use a graph to show rising global temperatures alongside subheadings detailing its effects on different regions.
• Technical writers for companies like Apple or Microsoft design user manuals and online help guides. They employ clear headings, step-by-step instructions, and diagrams to help users troubleshoot problems or learn how to operate new software or devices.
• Researchers and scientists present their findings in academic papers and reports. They use charts and graphs to visually represent data, making complex statistical information accessible to other scientists and policymakers reviewing their conclusions.

Assessment Ideas

Exit Ticket

Provide students with a short informational article. Ask them to identify one heading and one subheading, explaining in one sentence each what topic they introduce. Then, have them describe how a specific visual aid (if present) supports the article's main point.

Quick Check

Display two versions of the same informational paragraph: one without clear text features and one with effective headings, subheadings, and a simple chart. Ask students to write two sentences explaining which version is easier to understand and why, referencing specific features.

Discussion Prompt

Pose the question: 'Imagine you are creating a guide for a new school club. What text features would you use to make the information clear and engaging for potential members? Explain why each feature would be helpful.'

Frequently Asked Questions

What is the difference between a 'sidebar' and a 'caption'?

A caption is a short description that explains a specific image. A sidebar is a separate box of text that provides 'extra' or 'related' information that doesn't fit into the main flow of the article but is still relevant to the topic.

How do I know which 'structure' an author is using?

Look for 'signal words.' 'First, next, finally' signals chronological or process. 'Because, as a result' signals cause/effect. 'However, on the other hand' signals compare/contrast. 'The issue is, one way to fix this' signals problem/solution.

Why do authors use 'bold' or 'italic' words?

These are used to signal 'key terms' or 'vocabulary' that the reader needs to know. Often, these words are defined in a glossary at the end of the text or in a 'definition box' on the same page.

How can active learning help students understand text features?

Text features can seem 'invisible' because we use them unconsciously. Active learning, like the 'Information Designer' role play, forces students to use these features as 'tools.' When they have to decide where a subheading goes or what a chart should show, they realize that these features are not just 'decorations,' but essential parts of the communication process.
