The science of reading is a body of research that examines how children learn to read and how to teach them effectively. It is based on research from a variety of fields, including cognitive psychology, linguistics, and neuroscience.
The science of reading identifies five essential components of reading:
- Phonemic awareness: The ability to hear and manipulate the individual sounds (phonemes) in words.
- Phonics: The ability to use the relationship between letters and sounds to decode words.
- Fluency: The ability to read words accurately and quickly.
- Vocabulary: The ability to understand and use the words in a text.
- Comprehension: The ability to understand the meaning of a text.
The science of reading also identifies a number of evidence-based instructional practices that can help children learn to read effectively. These practices include:
- Explicit and systematic phonics instruction: Phonics instruction should be explicit and systematic, meaning that teachers should explicitly teach students the relationship between letters and sounds and provide them with opportunities to practice decoding words.
- Comprehensive vocabulary instruction: Vocabulary instruction should be comprehensive, meaning that teachers should teach students a variety of words, including high-frequency words, academic words, and domain-specific words.
- Text-based instruction: Instruction should be text-based, meaning that teachers should use real books and other texts to teach students the skills and strategies they need to read and comprehend.
The science of reading is a rapidly developing field, and new research is constantly being conducted. However, the research that is currently available provides a strong foundation for teaching children to read effectively.
