How the Brain Learns to Read
There are three regions of the brain associated with reading: phonological processor, orthographic processor, and phonological assembly.
Both phonological processor and orthographic processor are already at place in birth. The phonological assembly, which connects speech sounds with visual images (such as letters) has to be built through successful instructional experiences.
- Phonological Processor (Inferior Frontal Gyrus) - processes sounds
- Orthographic Processor (Occipito-Temporal Region) - processes letters and stores information for automatic word recognition
- Phonological Assembly (Parieto-Temporal Region) - connects letters to sounds

Here's a general overview of how the brain learns to read:
Decades of research have shown that reading doesn't come naturally. The human brain is not "hard-wired" for reading. It needs explicit instruction that literally rewires it creating connections that otherwise may not exist.
- Visual Processing: Reading begins with the visual processing of written text. The brain's visual system, including the occipital lobes at the back of the brain, analyzes the shapes, patterns, and individual letters of the written words. This initial visual processing lays the foundation for further steps in reading.
- Phonological Processing: Phonological processing is the ability to recognize and manipulate the sounds of language. When learning to read, the brain starts associating the visual symbols (letters) with the corresponding sounds (phonemes). The left hemisphere of the brain, including the superior temporal gyrus and parts of the parietal lobe, is involved in phonological processing. These regions help in connecting the visual representations of letters with their corresponding sounds.
- Orthographic Processing: Orthographic processing involves recognizing and representing the written word forms as a whole. The brain's ventral occipitotemporal cortex, including the visual word form area (VWFA), plays a crucial role in quickly recognizing familiar words and integrating their visual representations with their meanings. This area becomes specialized over time for efficient word recognition.
- Semantic Processing: Semantic processing involves understanding the meaning of words and sentences. The brain's left hemisphere, including the temporal lobes and the angular gyrus, is involved in linking word meanings to the concepts they represent. These regions help in comprehending the overall meaning of the text and connecting it to the reader's existing knowledge.

Theoretical Frameworks for Reading Comprehension
Simple View of Reading
The Simple View of Reading is a theoretical framework that explains reading comprehension as the product of two essential components: word decoding and language comprehension. It suggests that proficient reading is achieved when an individual possesses both the ability to decode words accurately and the ability to understand the meaning of those words.
- Word Decoding: This component refers to the process of recognizing and pronouncing words. It involves the ability to apply phonics skills, knowledge of letter-sound relationships, and other decoding strategies to accurately read words. Proficient readers can quickly and automatically decode words, which allows them to focus on understanding the text's meaning.
- Language Comprehension: This component involves understanding the meaning of words, sentences, and larger units of text. It encompasses a range of skills, including vocabulary knowledge, syntactic awareness, background knowledge, and the ability to make inferences and draw conclusions. Language comprehension allows readers to derive meaning from the text and construct a mental representation of the information.
RC = Word Decoding x Language Comprehension
In this equation, both word decoding and language comprehension are seen as independent factors that contribute to reading comprehension. A weakness in either component can hinder overall reading comprehension skills. For example, a student with strong word decoding skills but weak language comprehension may be able to accurately read individual words but struggle to understand the meaning of the text. Similarly, a student with weak word decoding skills may have difficulty reading accurately, even if their language comprehension skills are strong.
The Simple View of Reading emphasizes the importance of developing both word decoding and language comprehension skills in order to become a proficient reader. Effective reading instruction should target both components to ensure that students develop the necessary skills for reading and understanding text.

Scarborough Reading Rope
The Scarborough Reading Rope is a visual representation of the complex nature of reading, created by Dr. Hollis Scarborough, an American educational researcher and expert in reading development. The rope metaphor helps to illustrate the multiple strands or components of reading that interact and intertwine to form proficient reading skills.
The Scarborough Reading Rope consists of two major strands: the "word recognition" strand and the "language comprehension" strand. Each of these strands further comprises several subcomponents that contribute to reading ability:
Word Recognition Strand:
The rope metaphor signifies the interconnectedness and interdependence of these components. Reading is seen as a dynamic process that involves simultaneously using word recognition skills (such as decoding and sight recognition) and language comprehension skills (such as vocabulary knowledge and reasoning) to understand and derive meaning from text.
The Scarborough Reading Rope highlights the importance of addressing both word recognition and language comprehension skills in effective reading instruction. It emphasizes that proficient reading requires the integration of various components and the development of strong connections between them. By considering the different strands and subcomponents, educators can identify specific areas of strength or weakness in a student's reading skills and provide targeted support and instruction to foster well-rounded reading proficiency.

The Five Key Components of Reading Instruction
Phonemic Awareness
Phonemic awareness is the ability to identify and manipulate individual sounds (phonemes) in spoken words. It serves as a foundational skill for reading and is strongly linked to future reading success. Activities such as rhyming games and sound blending exercises help develop phonemic awareness in students.
Phonics
Phonics involves teaching the relationship between letters (graphemes) and sounds (phonemes). By understanding letter-sound correspondence, students can decode words and build their reading skills. Systematic and explicit phonics instruction is crucial for developing proficient readers.
Vocabulary Development
Building a robust vocabulary is essential for reading comprehension. Students with a strong vocabulary can understand and express ideas more effectively. Explicit instruction, engaging word games, and exposure to rich and varied texts contribute to vocabulary growth.
Fluency
Fluency refers to the ability to read with accuracy, speed, and expression. Fluent readers effortlessly navigate through text, allowing them to focus on comprehension. Repeated reading, guided oral reading, and modeling fluent reading contribute to the development of reading fluency.
Comprehension
Reading comprehension is the ultimate goal of literacy instruction. It involves understanding and making meaning from text. Effective comprehension strategies, such as activating prior knowledge, making connections, and asking questions, enable students to become active and engaged readers.

Stages of Reading Development
Reading development can be divided into three stages:
- Letters and sounds: Letter-sound knowledge is essential for both phonic decoding and sight-word learning. Phonics and phonemic manipulation must be proficient to allow for students to build a sight word bank or orthographic lexicon. To support this, students need sufficient practice and review in decoding and encoding, knowledge and application of concept skills, and exposure to decodable text.
- Phonic decoding: Early phonological awareness skills enable the development of letter-sound knowledge and should be targeted for direct instruction through first grade. Advanced phonological awareness skills should continue to be assessed and practiced through third grade to ensure that a solid orthographic lexicon is established.
- Orthographic mapping: Understanding orthographic mapping allows for teachers to support students who struggle to read. Orthographic mapping is the process that occurs when unfamiliar words become automatic sight words. The research on orthographic mapping explains how students develop this vast sight word bank for accurate and automatic word retrieval and also why students with reading problems struggle to develop this skill.
Research and Evidence-Based Practices
In recent years, research in the science of reading has shed light on effective instructional practices. It emphasizes the importance of explicit and systematic instruction in phonemic awareness and phonics, providing students with a strong foundation in decoding and word recognition skills.
What is explicit, systematic phonics?
Additionally, the research highlights the significance of vocabulary development, promoting wide reading experiences, and explicitly teaching comprehension strategies to support students' overall reading comprehension. Evidence-based practices advocate for the integration of all five components of reading instruction into a cohesive and balanced approach.
By addressing each component, we can nurture well-rounded readers who possess the necessary skills to unlock the meaning of text and become lifelong learners.
What is explicit, systematic phonics?
- Explicit means the learners are taught in a direct, structured way. When teachers use explicit instruction, they make lessons crystal clear. They show kids how to start and succeed on a task. They also give kids plenty of feedback and chances to practice.
- Systematic means the teacher guides the learners through each phonetic and decoding skill using a step-by-step, logical sequence. The scope and sequence grows in complexity and includes cumulative review.
