(The third in a series of 6 blogs unpacking nonfiction text structures)

When we read a nonfiction piece of writing to learn about the world around us, sometimes it is framed in a compare and contrast text structure.

When we read a nonfiction piece of writing to learn about the world around us, sometimes it is framed in a compare and contrast text structure. 

Whether the topic is ancient civilizations or future scientific breakthroughs, we are able to make meaning when we recognize that the text structure presents a compare and contrast relationship. When we, as readers, are guided and coached to readily identify a compare and contrast text structure, we are able to effectively read with purpose and comprehend. Likewise, when we write a nonfiction piece and effectively use a compare and contrast text structure to convey meaning we are able to achieve our purpose. 

Essential Questions

How does a compare and contrast text structure help to read for meaning? 

How does a compare and contrast text structure help to write with purpose?

Information text has one or more types of text structure based upon the author’s purpose:

Six Types of Nonfiction Text Structure

  1. Description-Explanation 
  2. Sequence-Time 
  3. Problem-Solution 
  4. Persuasive 
  5. Cause-Effect 
  6. Compare-Contrast

When readers know, understand, and apply these six types of text structure they are able to read with purpose and make meaning. 

When writers use one or more of the six types of text structure to inform and educate an audience about a subject, we effectively write with purpose.

Text structure refers to how the information within a written text is organized. This strategy helps students understand that a text might present a main idea and details; a cause and then its effects; and/or different views of a topic. Teaching students to recognize common text structures can help students monitor their comprehension

Benefits

Teachers can use this strategy with the whole class, small groups, or individually. Students learn to identify and analyze text structures which helps students navigate the various structures presented within nonfiction and fiction text. As a follow up, having students write paragraphs that follow common text structures helps students recognize these text structures when they are reading.

Create and Use the Strategy

To create the text structure strategy teachers should:

  1. Choose the assigned reading and introduce the text to the students. 
  2. Introduce the idea that texts have organizational patters called text structures.
  3. Introduce the following common text structures (see the chart below for more detailed information):
  • description 
  • sequence
  • problem and solution 
  • cause and effect
  • compare and contrast

4.  Introduce and model using a graphic organizer to chart the text structure. 

To use the text structure strategy teachers should:

  1. Show examples of paragraphs that correspond to each text structure.
  2. Examine topic sentences that clue the reader to a specific structure. 
  3. Model the writing of a paragraph that uses a specific text structure.
  4. Have students try write paragraphs that follow a specific text structure. 
  5. Have students diagram these structures using a graphic organizer. 

Examples

Text Structure Definition /Example Organizer
Description

This type of text structure features a detailed description of something to give the reader a mental picture.

Example: A book may tell all about whales or describe what the geography is like in a particular region.

 
Cause and Effect

This structure presents the causal relationship between a specific event, idea, or concept and the events, ideas, or concept that follow.

Example: Weather patterns could be described that explain why a big snowstorm occurred.

 
Comparison / Contrast

This type of text examines the similarities and differences between two or more people, events, concepts, ideas, etc.

Example: A book about ancient Greece may explain how the Spartan women were different from the Athenian women.

 
Order / Sequence

This text structure gives readers a chronological of events or a list of steps in a procedure.

Example: A book about the American revolution might list the events leading to the war. In another book, steps involved in harvesting blue crabs might be told.

 
Problem–Solution This type of structure sets up a problem or problems, explains the solution, and then discusses the effects of the solution.

Compare and Contrast is a text structure or pattern of organization where the similarities and differences of two or more things are explored. It is important to remember that with the compare and contrast text structure the text should be discussing similarities and differences. If the text only discusses similarities, it is only comparing. Likewise, if it only discusses ways that the things are different, it is only contrasting. The text must do both to be considered compare and contrast.

Example: Apples and oranges are both fruits, which means that they have seeds inside of them. Each has a skin, but orange skins are thick and easy to peel. Apple skins are thinner and do not peel easily. Oranges also contain more acid than apples, but both fruits are delicious.

Compare and Contrast Graphic Organizer

Identifying when the writer is comparing and contrasting is usually not difficult because the speaker will bounce back and forth between two subjects and this pattern is generally pretty easy to recognize.  However, here are some signal words that may indicate that the text is written using the compare and contrast organizational pattern: like, unlike, both, neither, similar, and different.
