Every day in the U.S., school district leaders are coming to the realization that the way we’ve been teaching reading needs to change. According to the Nations Report Card (NAEP), only 33% of fourth-grade students and 31% of eighth-grade students performed at or above Proficient in reading in 2022. While this is the case, 95% of students are capable of learning to read proficiently when taught with a curriculum based on the science of reading.
As a result, during the last two years, almost 20 states have made moves to scrap literacy curricula in favor of those based on the evidence of the science of reading, with California, Ohio, and Georgia being the most recent to join the movement. While it is true that many states are developing their curriculum to align with the science of reading, implementing the science of reading can be complex.
Breaking down the science of reading into a set of components might seem like the most logical way to begin understanding it, but this actually reflects a misunderstanding of the science of reading at the highest level. There are no components to the science of reading, simply because it is not an approach or philosophy. Instead, the phrase “science of reading” represents decades of gold-standard research that shows us the science behind how the human brain learns to read.
What many people think of as the components of the science of reading are the skills and instructional methods that have been proven effective in teaching reading. Skills like decoding are a key component in literacy, and the science of reading is the body of research that proves the importance of explicitly teaching such skills.
In this article, we look at how the body of research that makes up the science of reading can be more easily understood through the following four frameworks and models, which are all interconnected:
- The five pillars of reading instruction
- Scarborough’s Reading Rope
- The Simple View of Reading
- Structured Literacy
These approaches each have their own components and concepts to help us understand how we learn to read. When educators have a complete understanding of these instructional frameworks and models, they are able to effectively implement evidence-based practices in their classroom and help all of their students find reading success.
What are the Five Pillars of Reading Instruction?
The five pillars of reading instruction, also known as the five pillars of early literacy, are a set of key components developed by the National Reading Panel essential for reading proficiency. They include phonemic awareness, phonics, vocabulary, fluency, and comprehension. Each component plays a crucial role in developing strong reading skills, and educators who understand and effectively teach these pillars are increasing the chances their students learn how to read proficiently.
Research in cognitive psychology, linguistics, and neuroscience has provided a wealth of evidence-based strategies and practices for developing each of the five pillars of reading. Understanding the science behind these pillars can help educators design effective instruction that supports students in becoming strong readers. In the following sections, we'll dive deeper into each of the pillar components and explore how the science of reading informs our understanding of each one.
1. Phonemic awareness
Phonemic awareness is the ability to identify, manipulate, and distinguish individual sounds (phonemes) in spoken words. It involves understanding that words are made up of separate sounds and being able to hear, blend, segment, and manipulate those sounds. Research has shown phonemic awareness instruction is most effective when students are taught to manipulate phonemes with letters, when it explicitly focuses on one or two types of phoneme manipulations (rather than multiple), and when students are taught in small groups.
2. Phonics
Phonics refers to the relationship between letters and sounds in language. It involves understanding how letters represent sounds and using that knowledge to decode written words during reading and encode words during writing. Many people have the misconception the science of reading is solely based on phonics, but phonics is just one piece of a very large and complex puzzle. Research shows systematic phonics instruction “provides beginning readers, at-risk readers, disabled readers, and low-achieving readers” with a higher chance of learning how to read proficiently in comparison to other forms of instruction.
3. Fluency
Fluency refers to the ability to read text accurately, quickly, and with proper expression. It involves automaticity in word recognition, comprehension, and prosody. This study shows students with strong oral fluency skills are more likely to succeed in other areas of the literacy acquisition process. This is because fluency serves as a bridge between being able to read or decode words and being able to comprehend what is being read.
4. Vocabulary
Vocabulary refers to the words students must know to communicate effectively through reading and writing. It includes understanding the meaning of words, as well as how words are used in different contexts.
5. Comprehension
Reading comprehension is the ability to understand and make meaning from what has been read. It involves using background knowledge, decoding skills, vocabulary, and critical thinking strategies to construct meaning from text. Reading comprehension itself is the application of multiple skill components, and can be seen as the main goal of reading. The skills needed for reading comprehension can be broken down with the Simple View of Reading and Scarborough’s Reading Rope.
The Simple View of Reading & Scarborough’s Reading Rope explained
Scarborough's Reading Rope and the Simple View of Reading are two widely recognized models that explain the complex process of reading. While both models are similar in that they identify different components that contribute to reading proficiency, they differ in the way they conceptualize and prioritize these components. Both of these models are foundational ways of understanding the science of reading research explaining how the human brain learns to read.
The Simple View of Reading (SVR)
According to Gough and Tumner’s (1986) Simple View of Reading (SVR), reading comprehension is conceptualized through the combination of two skills: word recognition and language comprehension. The model is represented as a multiplication equation, showing that neither of these concepts is sufficient on its own—a lack of understanding of one concept could lead to overall reading failure. This is why it is so important for students to develop both alongside each other.
Decoding (Word Recognition) x Language Comprehension = Reading Comprehension
In the SVR, decoding is comprised of the skill components: phonology, orthography and morphology. Language comprehension is comprised of the components of syntax, semantics, pragmatics, and discourse. Struggling with any one of these subcomponents can lead to overall reading comprehension struggles.
Scarborough’s Reading Rope
With a slightly different skill component breakdown, Scarborough’s Reading Rope offers a visual of the different components that need to be woven together for skilled reading. These strands are separated into two categories: word recognition and language comprehension. These two sections (the same main components represented in the SVR) are further broken down into smaller “strands” that represent the different skills that go into each category. All of these strands are critical for skilled reading and are dependent upon one another.
Word Recognition is a combination of:
- Phonological awareness
- Decoding
- Sight recognition
Of these three, decoding is the element that helps bring everything together when it comes to word recognition. Decoding is the process of linking printed words or letters on the page to their spoken equivalents. A student’s ability to decode words begins with their understanding of the language sound system and then proceeds to have a grasp on the writing system through an understanding of phonology, orthography, and morphology.
Language comprehensionis the other necessary component of reading comprehension, and it makes up the top half of Scarborough’s Reading Rope. Language comprehension requires the combination of
- Background knowledge
- Vocabulary
- Language structures
- Verbal reasoning
- Literacy knowledge
While these skill components differ from the SVR’s underpinning components of semantics, pragmatics, syntax, and discourse, they both comprise the skills needed to understand language and sentence structure.
Where does Structured Literacy come in?
Structured Literacy (SL) is a phrase coined by the International Dyslexia Association® (IDA), and it refers to a specific way of teaching students how to read. This method of teaching has been shown to support all students, regardless of background or skill level. The SL approach to teaching reading is defined by these parameters:
Explicit
This means that concepts and skills being introduced to students are directly taught and practiced—educators should not assume students learn principles of literacy on their own or through exposure alone. The aim is to provide ample guidance and practice to help students acquire new literacy concepts. It is important to give immediate feedback to minimize the possibility of students learning and practicing concepts incorrectly.
Systematic and cumulative
Each concept students are taught should build on top of the previous concept they learned, and their teacher should explain how each new lesson fits into the whole. New skills should be presented in a logically ordered way, progressing from simple to complex. Each new concept builds upon the previous one, with teachers making sure to explain how each new lesson connects to the previous ones. The goal is to enable students to gradually develop automatic reading skills, which allow them to move from learning to read to reading to learn.
Hands-on, engaging, and multimodal
SL recognizes students learn best when they are engaged and active in the learning process. This combines listening, speaking, reading, and writing, which in turn develops a student’s language comprehension skills and fosters multimodal learning.The goal is to foster language comprehension skills by allowing students to experience learning in a more interactive and engaging way.
Diagnostic and responsive
This means educators are responsive to the needs of individual students. They should be continuously assessing student progress and adjust their teaching accordingly. Pacing, presentation, and practice for new concepts should be adapted to individual students’ skill levels and understanding, ensuring students who need more time and guidance get that support. By being diagnostic and responsive, SL ensures every student receives the support and guidance they need to develop literacy skills effectively.
A structured literacy approach will teach the skill components identified by the National Reading Panel, the simple view of reading, and Scarboroughs’s reading rope in an explicit, systematic, and responsive way that effectively helps all students learn to read.
Implementing the Science of Reading Components
Components like phonics, vocabulary, or syntax are but a small piece of science of reading-based instruction. As an ever-growing body of research, the science of reading continues to deepen our understanding of how we learn to read. The five pillars of early literacy, Scarborough’s Reading Rope, the Simple View of Reading, and Structured Literacy are all derived from the science of reading research. Educators can use the components within these frameworks and models to inform their teaching practices. By including explicit instruction in reading skills from phonemic awareness to vocabulary and semantics, teachers can make sure all students have the opportunity to achieve reading success.
