The Science of Reading: What Every Teacher Needs to Know

What Is the Science of Reading?

The science of reading is not a curriculum or a program. It is a body of research spanning decades and multiple disciplines (cognitive science, neuroscience, linguistics, education) about how people learn to read. This research has clear implications for instruction.

The Simple View of Reading

Reading comprehension = Decoding x Language Comprehension. Both are necessary. A student who can decode but does not understand language cannot comprehend. A student who understands language but cannot decode cannot read independently.

What the Research Says About Decoding

Systematic Phonics Works -- The evidence is overwhelming that explicit, systematic phonics instruction produces better reading outcomes than approaches that do not teach phonics systematically.

Phonemic Awareness Is Foundational -- The ability to hear and manipulate individual sounds in words is the strongest predictor of reading success. It must be taught explicitly, especially for students who do not develop it naturally.

Decodable Text Matters Early On -- Beginning readers benefit from texts that align with the phonics patterns they have been taught. This allows them to practice applying their decoding skills.

What the Research Says About Language Comprehension

Background Knowledge Is Critical -- Students who know more about a topic comprehend better when reading about it. Building knowledge across subjects directly improves reading comprehension.

Vocabulary Knowledge Predicts Comprehension -- Students need both breadth (knowing many words) and depth (knowing words well) of vocabulary to comprehend complex texts.

Read-Alouds Build Language -- Reading aloud to students exposes them to complex language structures, vocabulary, and ideas beyond what they can read independently.

Implications for Instruction

Teach Phonics Systematically in K-2 (and beyond for struggling readers).

Build Background Knowledge through content-rich instruction in science, social studies, and the arts.

Teach Vocabulary Explicitly using multiple exposures and meaningful contexts.

Read Aloud Daily at every grade level, choosing texts that stretch language and thinking.

Assess and Intervene Early when students are not making expected progress in decoding or comprehension.
