What Is Reading Comprehension?

Reading comprehension is the process of constructing meaning from written text through a purposeful, active interaction between the reader and the text. The word construct is deliberate: meaning is not simply extracted from the page like water from a tap. The reader builds it, assembling the text's information together with their own knowledge into a coherent mental representation of what the text is about.

Comprehension therefore involves far more than remembering facts. A reader must actively integrate the new information presented in the text with their existing knowledge and experiences, forming what researchers call a situation model—a mental picture of the state of affairs the text describes.

Two readers can read the identical words and build quite different understandings depending on what knowledge and attention each brings.

Consider the sentence: "The ice beneath Jacob's feet began to crack."

A skilled reader does far more than recognize the individual words. In a fraction of a second, the reader also:

• Visualizes the situation—a person standing on a frozen surface.
• Predicts possible outcomes—the ice may give way.
• Connects the information to prior experiences or knowledge that ice over water can be dangerous.
• Infers danger, even though the word "danger" never appears.
• Monitors understanding, confirming the scene makes sense.

None of these processes is stated in the sentence; all of them are generated by the reader. This single example illustrates that comprehension is an active, generative, knowledge-dependent process rather than a passive reception of words.

The Simple View of Reading

One of the most important theories assessed on the test is the Simple View of Reading, a foundational model that explains reading comprehension with elegant economy.

The Simple View of Reading states:

Reading Comprehension = Decoding × Language Comprehension

This formula proposes that successful reading comprehension is the product of two distinct capacities. The use of multiplication rather than addition is the model's most important and most tested feature: because the two factors are multiplied, if either factor is zero (or near zero), the product—comprehension—is also zero (or near zero). The two components cannot compensate for one another. A reader cannot be "so good at language" that it makes up for an inability to decode, nor can flawless decoding rescue a reader who cannot understand the language.

Decoding

Decoding is the ability to accurately and (eventually) automatically recognize the written words on the page—translating print into the spoken words it represents. This is the word-recognition capacity built through the phonological awareness and phonics instruction covered in Lessons 1 and 2.

Language Comprehension

Language comprehension is the ability to understand spoken language and derive meaning from it—vocabulary, syntax, background knowledge, and reasoning. Tellingly, this is the same capacity a person uses to understand a story read aloud to them; it does not depend on print at all.

A weakness in either area limits comprehension, and the model is valuable precisely because it helps teachers locate which area is weak.

Example 1: Strong Decoding, Weak Language Comprehension

A student reads every word in a science passage accurately but does not understand the scientific vocabulary or the concepts being described. The result is poor comprehension despite flawless reading. This profile characterizes some English language learners and students with developmental language disorders, whose word recognition outpaces their language understanding.

Example 2: Strong Language Comprehension, Weak Decoding

A student understands complex spoken explanations easily and has rich vocabulary and background knowledge, but struggles to decode printed words. The result is poor reading comprehension because the words cannot be reliably accessed in the first place. This profile is characteristic of dyslexia, in which language comprehension is intact but decoding is impaired.

Example 3: Strong Decoding and Strong Language Comprehension

A student reads accurately and understands language well. Both factors are strong, so their product—reading comprehension—is strong. This is the goal toward which all reading instruction aims.

The test often requires you to identify whether a comprehension problem is due to decoding, language comprehension, or both, and then select the appropriate intervention. Decoding issues call for phonics support, while language comprehension issues require vocabulary and knowledge-building. The key skill is matching instruction to the actual source of the difficulty.

Science of Reading Connection

The Simple View has been elaborated by Scarborough's Reading Rope, which expands each strand. The language comprehension strand braids together background knowledge, vocabulary, language structures, verbal reasoning, and literacy knowledge; the word recognition strand braids phonological awareness, decoding, and sight recognition.

Over time these strands grow increasingly tight and automatic, weaving into skilled, fluent reading. The Rope is useful because it shows comprehension depends on many interwoven sub-skills, not merely two.

Factors That Influence Reading Comprehension

Background Knowledge

Background knowledge refers to the information, concepts, and experiences a reader brings to a text before reading a single word. Readers never approach a text as blank slates; they interpret new information through the lens of what they already know. This prior knowledge is sometimes described as a schema—an organized mental framework into which new information is fitted.

For example, a student reading a passage about baseball who already understands innings, bases, pitchers, and batters will comprehend the passage far more easily than a student with no knowledge of the sport—even if the two students have identical decoding skill and vocabulary.

The knowledgeable reader can fill gaps, interpret references, and make inferences that the unknowledgeable reader simply cannot. A famous line of research demonstrated exactly this: readers' comprehension of a baseball passage depended more on their knowledge of baseball than on their general reading ability.

Instructional Practices

Teachers build and activate background knowledge through pre-reading discussion, building content knowledge systematically across science and social studies, providing relevant experiences (real or virtual), and explicitly previewing concepts a text will assume. Importantly, instruction should also build knowledge over time, not merely activate whatever students happen to already have.

Vocabulary Knowledge

Vocabulary plays a central role in comprehension, so central that vocabulary knowledge is one of the strongest single predictors of comprehension success. The logic is direct: readers cannot understand a text whose words they do not know.

Consider the sentence: "The archaeologist carefully examined the artifacts uncovered during the excavation." A reader unfamiliar with archaeologist, artifacts, and excavation will struggle to comprehend the sentence even if they can decode every word flawlessly. The decoding succeeds while the comprehension fails, because the words, though pronounced, carry no meaning for the reader.

Vocabulary knowledge supports comprehension at every level: literal comprehension (understanding what is plainly stated), inferential comprehension (reading between the lines), and critical analysis (evaluating the text). The relationship between vocabulary and comprehension is also reciprocal: wide reading builds vocabulary, and a larger vocabulary enables wider and deeper reading, creating an upward spiral for strong readers (and, again, a Matthew effect that can leave weaker readers behind).

Instructional Practices

Effective vocabulary instruction teaches words explicitly (especially high-utility "Tier 2" academic words that appear across many texts), provides multiple exposures in varied contexts, teaches morphology (roots, prefixes, and suffixes) so students can unlock related words, and fosters word consciousness—a curiosity about and attention to words. Pre-teaching essential vocabulary before reading a demanding passage is a common, effective practice.

Reading Fluency

Fluency refers to reading that is accurate, automatic, and expressive (read with appropriate phrasing and prosody). Fluent readers recognize words quickly and effortlessly, with little conscious attention devoted to the words themselves.

Fluency is best understood as the bridge between decoding and comprehension. Because the fluent reader's word recognition is automatic, their limited cognitive resources are freed to focus on meaning. This connects directly to the principle of limited cognitive capacity introduced in Lesson 1: the mind has finite attention, and if most of it is consumed by laboriously identifying words, little remains for the harder work of comprehension.

Students who struggle with decoding devote so much attention to identifying individual words that little mental energy remains for understanding. Such readers may reach the end of a sentence having expended all their effort on the words and retained nothing of the meaning.

The expressive dimension of fluency matters too: a reader who groups words into meaningful phrases and reads with appropriate intonation is demonstrating—and supporting—comprehension, whereas flat, word-by-word reading both reflects and worsens comprehension difficulty.

Instructional Practices

Fluency is built through repeated reading of the same passage, modeled fluent reading by the teacher, partner and echo reading, and reading of appropriately leveled connected text. The goal is never speed for its own sake; rushing without understanding is not fluency. Reading rate is meaningful only in service of comprehension.

Working Memory

Working memory refers to the ability to temporarily hold and manipulate information while simultaneously performing a cognitive task. It is the mental "workspace" in which the pieces of a text are assembled into meaning.

Reading places heavy demands on working memory. To comprehend, a reader must remember the content of previous sentences, connect ideas across paragraphs, track characters and events over time, and integrate incoming information with what came before—all while continuing to decode the current words. A reader who reaches the end of a long sentence having forgotten how it began cannot assemble its meaning.

Weak working memory can therefore interfere with comprehension, particularly with complex texts featuring long sentences, multiple characters, or intricate logical relationships. This also clarifies why fluency and automaticity matter so much: when decoding is automatic, it consumes little working memory, leaving more capacity available for holding and integrating ideas. Decoding and comprehension thus compete for the same limited resource, and freeing one supports the other.

Instructional Practices

Teachers reduce working-memory load by chunking text into manageable sections, using graphic organizers that externalize information so it need not all be held in mind, pausing to summarize at natural stopping points, and rereading to consolidate understanding before moving on.

Literal, Inferential, and Evaluative Comprehension

Reading comprehension occurs at multiple levels of depth, and these levels form a hierarchy of increasing cognitive demand. The three levels are sometimes summarized as reading on the lines (literal), between the lines (inferential), and beyond the lines (evaluative).

Literal Comprehension

Literal comprehension involves understanding information that is explicitly stated in the text. The answers are right there on the page; the reader simply locates and reports them. This is sometimes described as "reading the lines."

Example

Text: "Maria walked to the library after school." Question: Where did Maria go? Answer: The library. The answer is stated directly and requires no interpretation.

Skills Associated with Literal Comprehension

Literal comprehension includes identifying stated facts, details, events, settings, characters, and sequences of events. These are the who, what, where, and when questions whose answers appear verbatim or near-verbatim in the text.

Literal comprehension is the foundation upon which higher levels are built—a reader who cannot grasp what a text plainly says has no basis for inferring or evaluating. However, it is essential to understand that literal comprehension is necessary but not sufficient. Instruction that stops at the literal level (asking only fact-retrieval questions) leaves students unprepared for the deeper comprehension that reading demands and that the exam emphasizes.

Common Instructional Error

A teacher who assesses comprehension exclusively through literal recall questions may believe a student "comprehends" when the student is in fact only locating stated facts without genuine understanding. Balanced questioning across all three levels gives a truer picture.

Inferential Comprehension

Inferential comprehension requires the reader to combine information from the text with their own background knowledge to grasp meaning that is implied but not directly stated. This is "reading between the lines."

Example

Text: "Marcus grabbed his umbrella before leaving the house." Question: What can be inferred? Answer: It may be raining (or rain is expected). The text never mentions rain; the reader supplies that conclusion by combining the textual clue (grabbing an umbrella) with prior knowledge (umbrellas are used in rain).

Instructional Practices

Teachers build inference by modeling their own thinking through think-alouds ("The author didn't say it was raining, but I know umbrellas are for rain, so I'm inferring..."), asking "How do you know?" to make students cite text evidence plus reasoning, and using questioning frameworks such as Question-Answer Relationships (QAR) that help students distinguish "right there" answers from "think and search" and "author and you" answers.

Evaluative or Critical Comprehension

Evaluative comprehension, the highest level, involves making reasoned judgments about a text. The reader stands back from the text and assesses it. This is "reading beyond the lines."

Readers analyze the text's credibility, accuracy, effectiveness, and bias, as well as the author's purpose and craft. For example, a student might evaluate whether an author's argument is supported by sufficient evidence, whether a source is trustworthy, or whether an author's word choices reveal a particular slant. This level requires not only understanding what the text says and implies but also bringing critical reasoning and, often, outside criteria to bear on it.

Evaluative comprehension represents the most sophisticated level of understanding and is increasingly important in a world of abundant and uneven information, where readers must judge the reliability of what they read. It draws on and integrates the literal and inferential levels beneath it.

Instructional Practices

Teachers develop evaluative comprehension by asking students to assess the strength of evidence, compare how different texts treat the same topic, identify an author's purpose and point of view, detect bias or persuasive technique, and support judgments with reasons. These higher-order discussions are well suited to text-based dialogue and debate.

Comprehension Strategies

Effective readers deploy specific strategies before, during, and after reading, and these strategies can and should be taught explicitly. The strategies that follow are the evidence-based "toolkit" of skilled comprehension.

A vital instructional principle underlies all of them: the goal is not for students to perform strategies mechanically, but to internalize them as flexible habits of mind that support meaning-making. Strategies are means to comprehension, not ends in themselves.

The core comprehension strategies include:

• Activating prior knowledge
• Predicting
• Visualizing
• Questioning
• Monitoring comprehension (metacognition)
• Summarizing

Activating Prior Knowledge

Before reading, skilled readers call to mind what they already know about a topic. This pre-reading process primes the relevant schema, preparing the mind to connect incoming information to an existing framework so that new material has somewhere to attach.

Example

Before reading about volcanoes, students might discuss lava, eruptions, mountains, and natural disasters. This brief activation creates a mental framework into which the new details of the passage can be integrated, making them easier to understand and remember.

Activating prior knowledge increases engagement, supports vocabulary learning by situating new words in a familiar context, improves memory by giving new information an anchor, and enhances comprehension overall. It directly operationalizes the background-knowledge principle discussed earlier.

A crucial caveat for the exam: when students possess little or inaccurate prior knowledge, activation alone is insufficient—the teacher must actively build accurate knowledge before or during reading. Activating misconceptions can even harm comprehension, so the teacher's role includes correcting and supplying knowledge, not merely eliciting whatever students already believe.

Instructional Practices

Common techniques include K-W-L charts (what I Know, Want to know, and Learned), anticipation guides, pre-reading discussion, and previewing text features. These should surface and, where necessary, correct prior knowledge.

Predicting

Predicting involves anticipating what may happen next, based on text clues, prior knowledge, and knowledge of how texts are typically structured. A prediction gives the reader a purpose—a question to read forward and confirm or revise.

Example

A story begins: "Dark clouds gathered as the hikers climbed higher." Readers may predict that a storm is approaching or that the hikers may encounter danger. As reading continues, the reader checks the prediction against what actually unfolds, revising as needed.

Predicting keeps readers active and engaged, because they are continually forming and testing expectations rather than passively receiving words. The act of checking a prediction is itself a comprehension-monitoring behavior. Note that the instructional value lies in the reasoning behind a prediction and the habit of confirming it—not in whether the prediction turns out to be "correct."

Instructional Practices

Teachers model prediction through think-alouds, pause at strategic points to invite predictions and the evidence behind them, and prompt students to confirm or revise predictions as new information appears.

Visualizing

Visualizing involves creating mental images—sensory representations—while reading. The reader turns words into pictures, sounds, and even smells in the mind's eye, effectively making a "mental movie" of the text.

Example

Text: "The golden leaves drifted slowly across the quiet pond." Readers imagine golden leaves, calm water, and an autumn scene. This mental imagery makes the text concrete and vivid.

Visualization increases engagement and, importantly, strengthens memory: concrete mental images are easier to retain than abstract strings of words. It also serves as a quiet comprehension check—if a reader cannot form an image of what they are reading, that difficulty signals a breakdown in understanding.

Visualizing is especially powerful for descriptive literary text and for making abstract informational content more tangible.

Instructional Practices

Teachers support visualization by reading vivid passages aloud and inviting students to describe or sketch what they "see," by modeling their own imagery, and by gradually withdrawing illustrations so students generate images from the words themselves.

Questioning

Skilled readers ask questions before, during, and after reading. Self-generated questions focus attention, set purposes, and serve as ongoing checks on understanding. Questioning transforms reading from passive reception into an active inquiry.

• Before reading, readers ask: What will this text be about? What do I already know? During reading, they ask: Why did the character do that? What does this term mean? Does this fit with what I expected?
• After reading, they ask: What was the author's main message? What did I learn? What still confuses me?

Questioning promotes deeper comprehension because a reader searching for answers reads with heightened attention and purpose.

There is an important developmental shift here: instruction should move students from merely answering the teacher's questions to generating their own, since self-questioning is the hallmark of an independent, strategic reader.

Instructional Practices

Techniques include teacher modeling of self-questions through think-alouds, the QAR framework, "thick versus thin" question sorting (distinguishing deep, open questions from surface ones), and reciprocal teaching (described below), in which students take turns posing questions to peers.

Metacognition

Metacognition means thinking about one's own thinking. In reading, it takes the form of comprehension monitoring—the reader's continuous, often unconscious checking of whether the text is making sense. It is sometimes described as having a "click or clunk" sense: comprehension either clicks into place or clunks, signaling trouble.

Good readers notice almost immediately when understanding breaks down; this awareness is what makes repair possible. The defining difference between strong and struggling comprehenders is often not that strong readers never lose the thread, but that they notice when they do and take action.

Example

A reader realizes, "I just read that paragraph, but I do not understand it." That moment of awareness is metacognition in action; it triggers the repair strategies that follow.

Summarizing

Summarizing involves identifying and restating the most important ideas from a text in condensed form. A good summary includes the key information, excludes minor or redundant details, and is expressed concisely in the reader's own words.

Summarizing is simultaneously a comprehension strategy and a demonstration of comprehension.

Instructional Practices

Teachers develop summarizing through frameworks such as "Somebody-Wanted-But-So-Then" for narrative, "Get the Gist" routines, the deletion of trivial and redundant information, and the substitution of general terms for lists of specifics.

Graphic organizers help students sort important from unimportant information before composing the summary.

Identifying Main Idea and Supporting Details

Main Idea

The main idea is the central message or most important point of a passage—what the text is mostly about. It may be stated explicitly in a topic sentence or, more challengingly, left implied so that the reader must infer it from the details.

Example

Paragraph: "Dogs serve many roles in society. They assist people with disabilities, work with law enforcement, and provide companionship." Main idea: Dogs serve many roles in society. (Here the main idea is conveniently stated in the first sentence.)

Supporting Details

Supporting details explain, clarify, illustrate, or provide evidence for the main idea. In the example above, the supporting details are that dogs assist people with disabilities, work with law enforcement, and provide companionship. Each detail develops the central point.

Distinguishing main idea from supporting details is a frequently tested skill, and it is genuinely difficult for many students, who tend either to seize on a vivid but minor detail and mistake it for the main idea, or to confuse the broad topic (a word or phrase, such as "dogs") with the main idea (a complete statement about the topic, such as "dogs serve many roles in society").

This main-idea/supporting-detail relationship also connects directly to summarizing and to determining importance: identifying the main idea is the core of constructing a good summary.

Instructional Practices

Teachers teach this distinction using main-idea-and-details graphic organizers (a table or web with the main idea at the center and details branching off), by having students generate a one-sentence "what is this mostly about?" statement, and by explicitly contrasting topic, main idea, and detail so students learn the difference.

Literary Text Comprehension

Literary texts (also called narrative texts) are written primarily to entertain, to tell stories, or to communicate themes and human experiences. Examples include fiction, short stories, novels, poetry, drama, and folktales.

Because their purpose and structure differ from informational texts, they call for somewhat different comprehension strategies.

Key Literary Elements

Comprehending literary text depends on understanding its core structural elements, sometimes called story grammar:

• Character — the individuals in a story, including their traits, motivations, and how they change.
• Setting — the time and place in which events occur, which can shape mood and possibility.
• Plot — the sequence of events, traditionally moving through exposition, rising action, climax, falling action, and resolution.
• Conflict — the central problem driving the story, whether character versus character, versus self, versus nature, or versus society.
• Theme — the underlying message, lesson, or insight about life that the story conveys, usually implied rather than stated.

Of these, theme is typically the most demanding because it is abstract and almost always inferred; students frequently confuse the theme (a universal message, such as "perseverance leads to growth") with the topic or the plot summary (what literally happened).

Literary Comprehension Strategies

Skilled readers of literature draw on several analytic moves:

• Analyzing characters' motivations — understanding why characters act as they do
• Identifying themes — recognizing the deeper messages of a text
• Tracking plot development — following how events unfold across the narrative
• Examining relationships among characters — seeing how characters connect and influence one another
• Making inferences — deducing characters' emotions and intentions from their words and actions

Because literary texts rely so heavily on what is implied, inference is especially central to literary comprehension. Story maps and character analysis charts are common supports.

Instructional Practices

Teachers use story maps to externalize story grammar, character trait charts supported by text evidence, and questioning that pushes from plot ("what happened?") toward theme ("what does this story say about life?"). Discussion is particularly valuable for literary interpretation, where multiple defensible readings may coexist.

Informational Text Comprehension

Informational texts (also called expository texts) are written primarily to convey facts, explanations, and knowledge about the real world. Examples include textbooks, articles, biographies, reports, and scientific texts.

They make up an increasing proportion of what students read as they advance through school and dominate adult reading, which is why facility with informational text is a major instructional priority.

Informational texts pose distinctive challenges: they often introduce dense, unfamiliar vocabulary, assume background knowledge, and present information in structures that differ from the familiar arc of a story.

Comprehending them therefore leans heavily on background knowledge and vocabulary, and on the reader's ability to recognize how the text is organized.

Informational Text Features

A key to comprehending informational text is using its text features—navigational and explanatory elements that help readers locate, organize, and interpret information:

• Headings introduce and signal the topic of each major section.
• Subheadings organize information into subsections beneath a heading.
• Captions explain accompanying images or photographs.
• Charts and graphs present data visually, often conveying relationships more efficiently than prose.
• Tables organize information systematically in rows and columns for easy comparison.
• Diagrams illustrate processes, structures, or relationships visually.

Other common features include boldface or italicized key terms, glossaries, indexes, and tables of contents.

Skilled readers use these features strategically—previewing headings to anticipate structure, consulting a diagram to clarify a process—rather than ignoring them, and an important instructional goal is teaching students to actively use, not skip, these supports.

Informational Text Structures

Beyond surface features, informational texts are organized according to underlying structures, and recognizing the structure substantially improves comprehension because it tells the reader what kind of information to expect and how ideas relate:

• Description — provides characteristics, features, or examples of a topic (signal words: for example, characteristics, such as).
• Sequence / chronological order — presents events or steps in order (signal words: first, next, then, finally, before, after).
• Compare and contrast — examines similarities and differences between two or more things (signal words: similarly, however, in contrast, both, unlike).
• Cause and effect — explains how one event or condition leads to another (signal words: because, therefore, as a result, consequently, leads to).
• Problem and solution — identifies a problem and presents one or more solutions (signal words: problem, solution, resolve, in response).

Teaching students to notice signal words and to map structures onto matching graphic organizers (a Venn diagram for compare-contrast, a flowchart for sequence, a cause-effect chain) makes the organization visible and supports both comprehension and later writing in these structures.

Instructional Practices

Teachers explicitly teach each structure and its signal words, pair each structure with a corresponding graphic organizer, and conduct text-feature "walks" in which students preview and discuss headings, visuals, and bold terms before reading.

Instructional Practices That Improve Comprehension

Decades of research converge on a clear conclusion: comprehension is most effectively developed through instruction that is explicit, systematic, guided, and interactive. Each quality matters:

• Explicit — the teacher directly names, explains, and demonstrates each strategy rather than expecting students to discover it. The teacher makes the invisible thinking of skilled readers visible.
• Systematic — strategies are taught intentionally and cumulatively over time, in a planned progression, rather than addressed haphazardly.
• Guided — the teacher models strategies and then scaffolds student practice, gradually releasing responsibility as students gain competence (the "I do, we do, you do" gradual release of responsibility model).
• Interactive — students actively discuss texts and apply strategies in dialogue with peers and teacher, since talk about text deepens understanding.

Specific evidence-based methods include think-alouds (the teacher verbalizes their own in-the-moment thinking while reading), reciprocal teaching (described below), guided reading (small-group instruction with appropriately matched text), structured text discussions, and graphic organizers that externalize the structure of ideas.

A consistent exam theme is that explicit strategy instruction outperforms simply giving students time to read and expecting comprehension strategies to emerge on their own—they generally do not, especially for struggling readers.

A further research-based insight worth noting: while individual strategies are taught one at a time for clarity, the ultimate goal is flexible, integrated use of multiple strategies in coordination, as skilled readers do. Strategy instruction is a means to building independent, meaning-making readers, not a checklist to be performed for its own sake.

Reciprocal Teaching

Reciprocal teaching is a well-established, evidence-based comprehension approach structured around four interrelated strategies, practiced through structured dialogue about a shared text:

• Predicting — anticipating what the text will discuss next, based on clues and prior knowledge.
• Questioning — generating questions about the content to focus attention and check understanding.
• Clarifying — identifying and resolving sources of confusion, such as unfamiliar words or unclear passages.
• Summarizing — identifying and restating the most important ideas.

The defining feature of reciprocal teaching is the gradual release of responsibility: the teacher initially models and leads all four strategies, then progressively hands leadership of the discussion to students, who take turns acting as "teacher" and guiding their peers through the four roles.

Over time, students internalize the strategies and apply them independently.

Reciprocal teaching is powerful precisely because it bundles four high-value strategies into a single collaborative routine and builds the metacognitive, social, and independent dimensions of comprehension simultaneously.

Exam Tips: Lesson 1

When answering comprehension questions on the exam, keep these principles in mind:

• Reading comprehension depends on both decoding and language comprehension (the Simple View); because they are multiplied, a severe weakness in either one collapses comprehension, and instruction must target the actual source of difficulty.
• Background knowledge significantly influences understanding, and the knowledge-comprehension relationship produces a Matthew effect that widens gaps over time.
• Vocabulary knowledge is among the strongest predictors of comprehension success.
• Inference requires combining text evidence with prior knowledge; it is one of the most heavily tested skills and depends on background knowledge and vocabulary.
• Comprehension has levels—literal (on the lines), inferential (between the lines), and evaluative (beyond the lines)—and good instruction addresses all three, not just literal recall.
• Metacognition involves monitoring understanding and deploying fix-up strategies when comprehension breaks down; struggling readers often fail to notice the breakdown.
• Summarizing focuses on important information, not minor details, and requires determining importance.
• Distinguish topic (a phrase) from main idea (a complete statement about the topic).
• Literary and informational texts require somewhat different strategies; literary comprehension centers on story elements (with theme the hardest, because it is inferred), while informational comprehension leans on text features and text structures.
• Recognizing informational text structure (and its signal words) improves comprehension.
• Reciprocal teaching includes predicting, questioning, clarifying, and summarizing, taught through gradual release of responsibility.
• Explicit, systematic comprehension strategy instruction is more effective than expecting students to discover strategies on their own.
