Abstract
Making inferences during reading is a critical standards-based skill and is important for reading comprehension. This article supports the improvement of reading comprehension for students with learning disabilities (LD) in upper elementary grades by reviewing what is currently known about inference instruction for students with LD and providing detailed suggestions and a five-step process for teaching students to make text-connecting and knowledge-based inferences while reading. By bolstering this key reading comprehension skill in the upper elementary grades, teachers can better prepare students for the increased reading comprehension demands of middle school.
Reading with comprehension involves building and continuously revising a mental model of the text in memory (Kintsch & van Dijk, 1978). This mental model looks something like a “network, with nodes that depict individual facts and events, and connections that depict meaningful relations between them” (Rapp, van den Broek, McMaster, Kendeou, & Espin, 2007, p. 292). These connections are known as inferences. A reader makes inferences by establishing appropriate, meaningful connections between separate pieces of information literally stated in the text (i.e., “text-connecting” inferences) and between information literally stated in the text and the reader’s background knowledge (i.e., “knowledge-based” or “gap-filling” inferences). A text-connecting inference might connect a pronoun with the person or thing it refers to. A knowledge-based inference might draw on what the reader knows about people’s motivations to infer why a character performed a given action. Some text-connecting and knowledge-based inference types are more necessary (e.g., pronoun resolution, causal inferences) and some less necessary (e.g., predictive inferences) for reading comprehension. If the reader does not generate inferences that are necessary for making sense of the text then comprehension will suffer; the reader may understand individual sentences but will not be able to derive the overall meaning of the text.
Students with higher levels of inference skill score higher on tests of reading comprehension than do students with low levels of inference skill. This is true for both elementary-aged (Cain, Oakhill, & Bryant, 2004; Kendeou, Bohn-Gettler, White, & van den Broek, 2008) and adolescent readers (Ahmed et al., 2016; Barth, Barnes, Francis, York, & Vaughn, 2015; Cromley & Azevedo, 2007). Students with learning disabilities (LD) tend to make fewer inferences than their typically developing peers; in fact, they often fail to make inferences altogether when reading text (Barnes, Ahmed, Barth, & Francis, 2015; Barth et al., 2015; Denton et al., 2015).
The Common Core State Standards expect students not only to “read and comprehend complex literary and informational texts independently and proficiently” (National Governors Association, 2010) (i.e., CCSS.ELA-LITERACY.CCRA.R.10) but also to “make logical inferences” and “cite specific textual evidence … to support conclusions drawn from the text” (i.e., CCSS.ELA-LITERACY.CCRA.R.1). Students should “determine central ideas or themes” (i.e., CCSS.ELA-LITERACY.CCRA.R.2); “analyze how and why individuals, events, and ideas develop and interact” (i.e., CCSS.ELA-LITERACY.CCRA.R.3); and “assess the ways in which point of view or purpose shapes the content and style of a text” (i.e., CCSS.ELA-LITERACY.CCRA.R.9). In other words, the Common Core State Standards expect students to make the text-connecting inferences that support basic comprehension and also the knowledge-based inferences that enable readers to establish causality, draw conclusions, and infer important relationships.
But how can teachers help upper elementary students with LD make inferences when they read? This article describes types of inferences that are necessary for reading comprehension along with those that are not quite so important. Next, it details instructional procedures for helping upper elementary students with LD improve their inference skill during reading. The strategies and instructional procedures described in this article are derived from intervention research that has demonstrated benefits for struggling readers and/or students with LD.
Types of Inferences: What Is Essential?
Predictive Inferences: Not So Important
When teachers ask students to generate inferences, they often focus on predictive or forward inferences. They ask students to infer what will happen next based on clues in the text. However, research demonstrates that students who comprehend well do not usually make predictive inferences; and when they do, it is only because there are ample context clues pointing towards a specific prediction. For example, McKoon and Ratcliff (1992) determined that, when a reader encountered the sentence, “The director and the cameraman were ready to shoot close-ups when suddenly the actress fell from the 14th story,” he or she typically did not infer that the actress died and perhaps ought not. If a reader generates an incorrect prediction and subsequent text refutes it, comprehension difficulties are likely to result. If anything, the reader is more likely to infer something broader and more general (e.g., something bad happened). For these reasons, it probably makes little sense for teachers to prompt students to make specific predictive inferences while reading. Instead, teachers will help students most by focusing on the inference types described next.
Text-Connecting Inferences
Text-connecting or referential inferences are often ignored in the classroom, partly because expert readers make text-connecting inferences so effortlessly that they are not even aware of having made them. Nevertheless, these inference types have been found to be most consistently important for reading comprehension (van den Broek, Beker, & Oudega, 2015), and children with LD often do not make this type of inference effortlessly and consistently. Text-connecting inferences require the reader to connect two separate pieces of information literally stated in the text. There are three important categories of text-connecting inferences: anaphoric, lexical, and inferential.
Anaphor Resolution
This type of inference requires students to connect a noun or noun phrase with the word or phrase to which it refers. For example, in order to form a coherent mental model of the sentence, “Rafael was cold, so Omar gave him his jacket,” the reader must infer that the “him” refers to Rafael, whereas the “his” most likely refers to Omar. There are other nonpronoun noun phrases for which readers must determine referents. Consider these sentences: “If sunlight did not reach the savannah’s grasses, they would die. Antelopes and other animals that eat the grasses would disappear. And the carnivores that depend on those grazers for food would disappear too.” It is necessary for the reader to connect “grazers” to the phrase it refers to in the previous sentence (i.e., antelopes and other animals that eat the grasses) as well as to infer that “they” in the first sentence refers to “grasses.” Although all three of these examples are within single sentences or between adjacent sentences, anaphor-resolution inferences must often be made across larger chunks of text.
Lexical Inferences
A reader must make a lexical inference (Stafura & Perfetti, 2015) in order to comprehend the following sentences: “While Cathy was riding her bike in the park, dark clouds began to gather, and it started to storm. The rain ruined her beautiful sweater” (Stafura & Perfetti, 2015, p. 20). In order to comprehend, the reader has to associate the word “storm” with the words “dark clouds,” and the word “rain” with the word “storm.” The reader then has to make the implicit connection that the dark clouds caused the storm, which included rain. Although proficient readers may generate lexical inferences effortlessly, students with LD often require explicit instruction in generating inferences of this type.
Inferring Word Meanings
Finally, readers must make text-connecting inferences to determine word meanings from context. Text often contains words that are not part of the student’s oral language vocabulary; word meanings need to be inferred from context. For example, the reader may infer the meaning of the word “herbivore” based on words and phrases in the following text: “All elephants are herbivores. They eat grasses, bark, twigs, leaves, and fruit.” Because students with LD often have difficulty making inferences for which context must be used to infer word meaning (Cain, Oakill, & Lemmon, 2004), it is important for teachers to provide students with strategies to infer word meanings from clues in text.
Nonpredictive Knowledge-Based Inferences
There are a variety of nonpredictive knowledge-based inferences that skilled readers make in order to establish and maintain reading comprehension. These inferences require the reader to go beyond the text and draw on background knowledge. For example, take the following sentences: “The campfire started to burn uncontrollably. Tom grabbed a bucket of water” (Bowyer-Crane & Snowling, 2005, p. 192). In order to understand why Tom grabbed a bucket of water, it is necessary for the reader to make a causal connection by activating the background knowledge that water puts out fire and relate the second sentence to the first by generating the inference that Tom grabbed the bucket of water because he was trying to put out the fire. Readers must frequently make causal inferences in order to explain or establish logical antecedents of events or information in one sentence by connecting them to events or information in another sentence. They must also sometimes generate spatial inferences (i.e., Where are the protagonists and how are they moving around in a particular setting?), temporal inferences (i.e., How has the author jumped backward or forward in time while telling a story?), and inferences about intentions, motivations, emotions, and/or traits that are either crucial for establishing comprehension immediately or inform comprehension during subsequent sections of text (van den Broek et al., 2015). For example, it is sometimes important to understand a character’s motivations, goals, or emotions in order to understand the character’s actions or reactions to other characters and situations.
Inference Instruction
Effective inference instruction helps students to
identify clues or key words in the text and use these key words to furnish answers to inferential questions,
activate background knowledge and interweave this knowledge with information in the text during reading, and
generate or answer inferential questions as a way of identifying gaps in text, confirming tentative inferences, and/or improving the automaticity of inference generation (Hall, 2015).
Teachers can employ the key word approach to help students identify relevant words, phrases, or sentences in text that need to be integrated with other information in text or with the reader’s background knowledge. First, the teacher will identify the teaching point in simple, student-friendly language: “I’m going to teach you how readers look for important clue words in the text and then combine these clue words with their knowledge about the world to make an inference, or ‘solve a mystery’ in the text.” After explicitly identifying this teaching point, the teacher will introduce a passage like the passage below and think aloud to model how a reader identifies “wave” as a clue word indicating that the story setting was a beach.
Billy was crying. His whole day was spoiled. All his work had been broken by the wave. His mother came to stop him crying. But she accidentally stepped on the only tower that was left. Billy cried even more. (Yuill & Oakhill, 1988, p. 38)
For the benefit of students, the teacher will think aloud:
What’s going on here? I know Billy is crying, but what happened to make him cry? Where is he, even? “Crying” and “spoiled.” Hmm. They don’t help me. There are a whole lot of things that could spoil a day and make a boy cry. But “wave!” Oh, maybe “wave” is an important clue word!
After thinking aloud about the possible settings indicated by “wave,” the teacher will again model, by thinking aloud, how she links “wave” with “tower” in order to infer that Billy was at the beach and the tower was a part of a sand castle: Billy was crying because his sand castle was wrecked by a wave. Once the teacher models her thinking, she will then provide students with another, similar passage and encourage students to think aloud as they connect clue words to make an inference.
Teachers can also show students how to activate prior knowledge and integrate this knowledge with information in text in order to generate inferences as they read. This can be as simple as asking students a question about their previous experiences with an important idea in a story prior to reading. Then, students can be encouraged to hypothesize about what might happen under similar circumstances in the story they are about to read. For example, prior to reading a story, Hansen and Pearson (1983) asked students to “tell us about a time when you were embarrassed about the way you looked” (p. 823). After listening to students’ responses, the teacher can let students know that, “in our next story there is an old man who is embarrassed about the way that he looks,” and ask them, “What do you think is the thing that embarrasses him?” The purpose of these questions is not to predict forward what will happen in the text but rather to give students practice building, activating, and integrating relevant background knowledge with information in text.
Finally, it is effective for teachers simply to prompt students to generate and answer inferential questions during and after reading a text. Teachers can invite students to act the part of the teacher in creating inferential questions about a recently read passage in order to quiz peers. Sentence starters or example inference questions (e.g., “Who is [pronoun]?” “What is the meaning of [unfamiliar word] based on clues in the text?” “Why do you think … ?” “What caused … ?” or “How did X lead to … ?”) are often helpful in guiding students to create inferential questions.
Alternatively, teachers can give students opportunities to discuss answers to teacher-generated inferential questions. When students are generating very few knowledge-based inferences as they read, it is most effective for teachers to ask students the general question, “How does the sentence you just read connect with something that happened before in the story?” at regular intervals during reading (McMaster et al., 2012). When students are generating knowledge-based inferences but these inferences are inaccurate and not grounded in textual clues, it is most effective to prompt students to make specific causal connections, asking them “Why did X do Y?” or “What caused Z to happen?” (McMaster et al., 2012).
A Step-by-Step Guide to Inference Instruction
Let’s imagine that a teacher, Ms. Soto, is working with small groups of fifth-graders with LD. Below are the steps she would follow to implement inference instruction in her classroom (see Note 1). The five steps described in this section draw on principles of effective inference instruction for students with LD (Hall, 2015, 2016) as well as on principles of effective instruction for students with LD more generally, including the idea that explicit and systematic instruction benefits students with learning difficulties more than inductive approaches to instruction, for both basic and complex, high-level skills (Biancarosa & Snow, 2006; Faggella-Luby & Deshler, 2008).
Preparation
something needs to be explained (e.g., “Why did he do/say that?”),
the referent of a pronoun or another anaphor is ambiguous (e.g., when there are two male characters and one of them needs to be connected to the “he” in a sentence), and
there is a tricky word that most students will not know but whose meaning is decipherable from context clues.
Because of the memory and attention capacity limitations of many students with LD as well as the consistent findings of disproportionate effects on inference making for students with reading difficulties as text distance increases (Barth et al., 2015; Cain et al., 2004), Ms. Soto may want to scaffold instruction so that students initially make inferences across only very short text distances. For example, Ms. Soto will make sure that context clues supporting a text-connecting inference of word meaning are within a sentence adjacent to the word. As another example using a knowledge-based inference, Ms. Soto will make sure that a causal antecedent (e.g., “He had a pounding headache”) that is an ingredient in an inference is in a sentence close to its consequence (e.g., “He rummaged around in the drawer for the pills that his mother had said were there”). When she asks, “Why was he looking for pills?” her students will not have to look far for the character’s motivation. Eventually, Ms. Soto will support students’ generation of inferences across longer distances by modeling long-distance inference generation and providing students opportunities for guided practice paired with corrective feedback.
Define Inference and Describe Routines
consider answer options;
discuss, debate, and find evidence to support given answers; and finally
reach consensus and scratch off an answer on a scratch-off answer sheet.

The process of teaching students how to engage in productive small group discussions will likely take longer than one lesson. After the introductory lesson, Ms. Soto will need to step in and coach students frequently during partner/small-group conversations, asking, “What information from the text did you use to make that inference?” or reminding them to discuss the answers to inference questions with multiple-choice answer options covered by their index cards.
Future Lessons: Teaching Students How to Make Inferences
Provide explicit instruction in generating specific types of text-connecting and knowledge-based inferences.
Name the kind of inference that is the focus of instruction (this provides the student with declarative knowledge).
Explain in step-by-step fashion how to make this kind of inference (this provides the student with procedural knowledge).
Describe when it makes sense to make this kind of inference (this provides the student with conditional knowledge).
Model making this type of inference while reading a section of text by thinking aloud.
Provide opportunities for guided practice combined with teacher corrective feedback. Feedback should include teacher explanation and thinking aloud that models accurate inference making rather than only an assessment of right or wrong. Students should also receive opportunities to think aloud, articulating why/how they made an inference, and why/how they made a correction to their inference process (Pashler et al., 2007).
Provide opportunities for independent practice reading and answering inferential questions in small groups.

Sample Inference Instruction Lesson Script.
If students are having difficulty understanding the ingredients of a knowledge-based inference, Ms. Soto can scaffold their understanding by using graphic organizers that make visible the gaps in text for which students must supply missing background knowledge and the way in which both the reader’s knowledge and information from the text contribute to an inference (Elbro & Buch-Iversen, 2013). For more research supporting the use of graphic organizers in instruction for students with LD, see Dexter and Hughes (2011) and Kim, Vaughn, Wanzek, and Wei (2004). Figure 4 represents an example of a graphic organizer that Ms. Soto could use during inference instruction. When introducing graphic organizers, Ms. Soto will first use oral language or visual scenarios. For example, she might show them an illustration from a wordless book like The Lion & the Mouse (Pinkney, 2009). One page depicts an owl, swooping down from above, and a mouse dashing into a hole in a hollow log. Displaying this page, Ms. Soto can model for students how she brainstorms what she already knows about mice and owls and combines this knowledge with what she sees on the page to make an inference: The mouse is running away because he’s afraid the owl will eat him. Once students are proficient at filling in the “information from text,” “information from the reader,” and “inference” graphic organizer boxes, Ms. Soto will guide students in using graphic organizers to generate inferences while reading text. Graphic organizers may be particularly helpful for teaching students to make inferences in informational text, which require students to frequently activate prior knowledge in order to make inferences. Graphic organizers used with informational text will help Ms. Soto keep track of prior knowledge that students do not have so that she can explicitly build this knowledge.

Example Graphic Organizer for Use During Inference Instruction. The inference displayed in this graphic organizer was generated while reading Wonder (Palacio, 2012).
After she provides explicit instruction and models making an inference of a particular type, Ms. Soto will give students opportunities for guided practice, making this inference type while she listens and provides corrective feedback. During the independent practice portion of instruction, Ms. Soto will instruct students to read with a partner or in a small group, stopping at specific points to read and discuss inference questions, as described in Step 2. She will again provide immediate corrective feedback when students submit answers to questions. One way to do this is by means of a scratch-off answer sheet (e.g., Immediate Feedback Assessment Technique forms; Smith, 2013).
Conclusion
Skill in generating inferences is critical to the reading comprehension of students in the upper elementary grades, and inference making is a key focus of the Common Core State Standards (National Governors Association, 2010). Students with LD have particular difficulty making inferences, but they also have more to gain than typically developing students from explicit inference instruction (Hall, 2015). For these reasons, it is tremendously important to teach struggling readers in the upper elementary grades how to generate text-connecting and knowledge-based inferences. Teachers can do this by following the steps laid out above:
choose a text;
mark stopping points, keeping in mind what you know about places in text where it’s necessary for readers to make inferences;
define “inference” and introduce the daily reading and question-answering routine;
build students’ background knowledge related to the topic of the text; and
provide explicit instruction, including declarative, procedural, and conditional knowledge, in generating specific types of text-connecting and knowledge-based inferences, with a reduction in the time spent asking students to generate predictive knowledge-based inferences.
Explicit inference instruction can incorporate the same components used in explicit reading comprehension strategy instruction more generally, including teacher modeling via think-alouds, opportunities for both guided practice and independent practice with immediate corrective feedback. Given access to these types of teaching and instructional supports, struggling readers can reap tremendous benefits from inference instruction.
