What Does âIntroducing a Topicâ Mean?
A fundamental step of effective informational writing is introducing the topic of a piece in a clear and engaging way. The Common Core Writing Standards highlight the importance of this concept, as Standards W.3.2a, W.4.2a, and W.5.2a emphasize the value of introducing a topic when writing informational text. In this chapter, weâll discuss the following: what âintroducing a topicâ means, why this concept is important for effective informational writing, a description of a lesson on this concept, and key recommendations for helping your students effectively introduce topics in their own informational writing.
Letâs begin by examining what it means to introduce a topic. An introduction to a piece of informational writing is an opening section of one or more paragraphs that provides a brief âfirst lookâ at subject matter that will be further developed later in the text. For example, the informational book Reptiles by Melissa Stewart (2001) contains an introductory paragraph that shows the reader what the rest of the book will address in more detail: âA snake flicks its long tongue as it slithers along the ground. A turtle sits on a rotting log and basks in the sun. A crocodile grabs a fish with its mighty jaws. These are the images that come to mind when someone says the word âreptileââ (p. 5).
Stewartâs introduction provides enough information to illustrate to the reader that this book is about reptiles, but doesnât yet go into a great amount of detail. The âfirst lookâ provided by this introduction conveys the topic of this book, inviting readers to continue reading the text. In the next section of this chapter, weâll consider why creating an effective introduction is important to well-written informational texts.
Why Introducing a Topic is Important to Effective Informational Writing
Introducing a topic is important to effective informational writing because a well-crafted introduction should perform two key actions: 1) Engage the reader; and 2) introduce key content. A strong introduction to a piece of informational writing does more than begin a pieceâit opens the work in a clear and purposeful way that shows the authorâs ability to capture the readerâs attention while also conveying basic information about the bookâs topic. Figure 1.1 illustrates the two key actions introductions perform and why each one is important.
In this section, weâll discuss why these concepts are related to an effective introduction using some published works to illustrate how professional writers apply these principles to their own introductions. Letâs begin by examining the opening section of Gary W. Davisâ (1997) informational text Coral Reef: âThe waters of the Caribbean Sea are warm and clear. On the surface, everything appears peaceful. But just below, rising from the bottom of the sea, there is a very busy place. It is the underwater community of the coral reefâ (p. 4). In this introductory passage, Davis both engages the reader and introduces key content. Letâs take a look at how he achieves each of these results.
First, weâll examine the way Davis grabs the readerâs attention. The first two sentences of this introductory paragraph draw the reader in through descriptive language that allows the reader to visualize the Caribbean Sea. Without these sentences, we readers wouldnât be engaged with the text in such a clear and effective way. Davisâ description of the âwarm and clearâ Caribbean Sea waters and his statement that âeverything appears peacefulâ appeal to the readerâs senses and allow a reader to envision him- or herself in this environment. Once the reader is able to picture him- or herself in this beautiful Caribbean Sea setting, Davis skillfully introduces the bookâs content.
Figure 1.1 Key Actions Introductions Perform and Why they are Important
Figure 1.2 How the Introduction to Coral Reef Performs the Key Actions of an Introduction
In the third and fourth sentences of this paragraph, Davis transitions from language meant to engage readers to introductory information about the bookâs content. The third sentence, âBut just below, rising from the bottom of the sea, there is a very busy placeâ shifts the readerâs attention away from the waterâs surface, while the fourth sentence focuses readers specifically on âthe underwater community of the coral reef.â After reading this paragraph, the reader clearly understands that Davisâ book will focus on coral reefs. However, Davisâ introduction does more than simply say, âThis text is about coral reefsâ; it begins by drawing the reader in with an appealing sensory description of the Caribbean Sea and then transitions from that opening image to a specific mention of coral reefs, the bookâs focal topic. Figure 1.2 highlights the features of this introduction, identifying the two key actions performed by introductions and which components of Davisâ text perform each of these actions (a blank, reproducible version of this chart that you can use in your classroom is included in the appendix).
In the next section, weâll take a look inside a third-grade classroom where I helped students understand the importance of crafting an effective introduction.
A Classroom Snapshot
Itâs a Wednesday morning, and the third graders Iâm working with are absolutely humming with energy. They spill into the classroom and take their seats, looking up at the question Iâve written on the whiteboard: âHow would informational texts be different without their introductions?â
This is my third class working with these students on the importance of introductions to informational writing. In our first meeting, I showed students examples of especially effective introductions in published informational texts. During our second meeting, I talked with the students about the key actions introductions perform, using charts such as those in Figures 1.1 and 1.2 to highlight the purposes of introductions and how published authors achieve those purposes in their works. Today, my students will be enhancing their understandings of the importance of effective introductions by considering how published informational texts would be different without their introductions. The goal of this lesson is to further increase studentsâ awareness of why well-crafted introductions are important components of strong informational texts.
I ask someone to read the dayâs âBig Questionâ out loud, and a young lady in the front of the room quickly complies. After she reads the question, I explain that it represents the focus for the dayâs work. âToday, weâll work together to answer this question: âHow would informational texts be different without their introductions?â To figure this out, weâll look together at an example of a published informational text. Weâll first look at this example as it was originally writtenâwith its introductory paragraphâand then weâll examine how it would look without this introductory paragraph. After we do this, weâll come back to our Big Question of the day and think about how this published informational text would be different if it didnât have its introduction.â
The students nod, and I direct their attention to a section of text from Caroline Arnoldâs (1980) informational work, Electric Fish, which Iâve projected to the front of the room. The selection I share with the students, which contains the bookâs opening paragraph and the first few sentences of the second paragraph, looks like this:
Did you know that an electric eel can produce enough electricity to shock a horse? Did you know that a shark is able to find a fish hidden in the sand because it can feel a small amount of electricity given off by the fish? Did you know that some fish can âtalkâ to each other with electric signals? All of these fish have a unique sensitivity to electricity.
Some fish can produce an electric current. The electricity is made by a special part of the fishâs body called an âelectric organ.â The electric organ can be very big or very small. (pp. 3â4)
I read the passage out loud, asking the students to follow along. Once Iâve finished reading it, I ask the students what they noticed about the introduction: âWhat works about this introductory paragraph? Think back to our conversations about the key actions introductions perform.â
âIt gets your attention,â responds one student, a young man seated at one of the back tables. âThe questions at the beginning get you interested.â
âYeah!â interjects another student. âLike the part about the eel being able to shock a horse. That got my attention. It would take a lot to shock a horse!â
âGreat job, both of you,â I reply. âThis introductory paragraph definitely grabs us and gets us to pay attention. Remember that we talked about introductions doing two key thingsâgetting the readerâs attention and introducing key content, like the main information the book will discuss. Do you think this introductory paragraph introduces key content?â
Hand shoot up around the room. I call on a young lady, who explains, âI think it does. It talks about fish and electricity, and thatâs what the book is about.â
âVery good point,â I respond. âThis book is definitely about fish and electricity, and this opening paragraph clearly shows that. It introduces the key content that some fish have a unique sensitivity to electricity.â
âNow,â I continue, âIâm going to ask you to think about what the opening of this book, Electric Fish, would look like if it didnât have its introductory paragraph.â
I place the chart in Figure 1.3 on the document camera so that the text projected to the front of the room now contains the original beginning of Electric Fish as well as a revised version of the beginning of the book without the introductory paragraph.
I read both versions out loud and ask the students to follow along silently as I do so. Once I finish, I ask the students to connect back to the dayâs âBig Questionâ by considering the following question: âHow is the beginning of Electric Fish different without its introductory paragraph?â
I call on a young lady who has quickly raised her hand. âThe introductory paragraph gets you interested and shows what the bookâs going to be about,â she explains. âThe part on the right, without the [introductory] paragraph, doesnât do those things. It just dives right in.â
Figure 1.3 Original Beginning of Electric Fish and a Revised Beginning with the Introductory Paragraph Removed
âThatâs really well said,â I reply. âWithout the introductory paragraph, this book just dives right in. The author doesnât get a chance to grab our interest and introduce us to the topic like she does in the original version. So, how do you think informational texts would be different without their introductions?â
âWithout the introduction,â answers a student, âthe text would just start talking about the topic without getting us interested or showing us what the book is about. The introductionâs kind of like the beginning of a movie when they first show you the characters and whatâs going on. The movie would be confusing if it didnât have that beginning.â
I smile, thrilled with the studentâs comparison: âExcellent connectionâI love that comparison you made! Introductions are really important aspects of informational writing. All of you did a great job today of thinking about this. In our next class, weâll work on crafting our own introductions to the informational texts that weâll be writing.â
Recommendations for Teaching Students about Introducing a Topic
In this section, I describe a step-by-step instructional process to use when teaching students about introducing a topic in informational writing. The instructional steps I recommend are: 1) Show students examples of introductions from published informational texts; 2) Talk with students about the key actions introductions perform; 3) Ask students to consider how published informational texts would be different without their introductions; 4) Work with students as they craft their own introductions to informational texts; and 5) Help students reflect on why their introductions are important components of their informational writings. Each of these recommendations is described in detail in this section.
- Show students examples of introductions from published informational texts.
I view this mentor text use as the foundation of effective writing instruction. By showing our students examples of outstanding introductions, we are allowing them to learn about effective writing directly from expert informational authors. The examples featured in this chapter from Reptiles, Coral Reef, and Electric Fish are excellent models of introductions and can certainly be used successfully in many classes. However, I also recommend that you keep your studentsâ particular interests in mind when selecting mentor texts to share with them. I have found that when students interact with examples that align with their interests, they are especially likely to be receptive to instruction related to those examples. Once youâve shown your students examples of effectively written introductions from published texts, you can think about the next step of this process: considering the key actions that introductions perform.
- 2. Talk with students about the key actions introductions perform.
This next step is firmly rooted in this bookâs toolkit approach. Now that the students have seen examples of strong introductions, we teachers can talk with them about why introductions are important tools for effective writing. In order for students to understand the importance of a strongly written introduction to an exemplary piece of writing, they must understand the key functions of introductions: 1) Engage the reader; and 2) introduce key content. To help students understand these actions that introductions perform, I recommend beginning by showing them the chart depicted in Figure 1.1. This chart describes each of the actions introductions perform and explains why these actions are important.
Once you have discussed this chart with your students and you are comfortable with their understandings, talk with them about how a published text performs these functions. To do this, present your students with an introduction from a published work and ask them to comment on which sentences from the text are used to engage the reader and which are used to introduce key content. I recommend showing your students an example of your analysis of a text before asking them to do the same on their own. I like to show my students the information in Figure 1.2 so that they can see how Iâve divided the introduction of Gary Davisâ Coral Reef into these categories. Once Iâve discuss...
