Writing & Reading: Why One Without the Other Holds Students Back
When we talk about reading intervention, most attention goes to decoding: phonics, phonological awareness, fluency.
These are essential. But there’s growing evidence—neuroscience, cognitive psychology, and leading practitioners—that
writing (encoding) is equally vitalFor many students, especially those with dyslexia, neglecting writing limits growth, comprehension, and long-term literacy.
What Reading vs. Writing Mean in the Brain
Reading ≈ Decoding + Comprehension: Recognizing letter‐sound correspondences, retrieving word forms from memory, making meaning of text.
Writing ≈ Encoding: The reverse process: translating sounds and language into letters, spelling, word form, sentence construction. It engages motor processes as well as orthographic and morphological skills.
Neuroscience confirms that reading and writing share overlap (orthographic knowledge, phonology) but also activate distinct brain regions. For instance, in dyslexia, the left temporo-parietal cortex (important for phonological decoding) shows under-activation, and writing tasks can help engage those networks more directly.

What Experts Are Saying
The Science of Reading frameworks emphasize not only phonemic awareness and decoding but also phoneme-to‐grapheme mapping, spelling, morphology-based instruction, and explicit writing practice. These are essential to build the “reverse” pathway in literacy. Lexia+2Haskins Laboratories+2
Recent meta-analyses of morphological interventions (working with meaningful word parts rather than just memorizing whole words) show improvements in reading, spelling, and writing outcomes. Teaching morphology aids both decoding and encoding. ILA Online Library
For students with dyslexia, encoding is often more effortful: spelling is inconsistent, handwriting can tax working memory, and organizing thoughts in writing may lag. When writing is scaffolded and explicitly taught, significant gains are possible. ceedar.education.ufl.edu+1
Why Writing is Often Overlooked — But Shouldn’t Be
Schools may prioritize reading fluency and comprehension because of assessment pressures. Writing is harder to measure, slower to develop, and often seen as a “bonus.”
Teachers may feel less confident in teaching writing structure, morphology, spelling instruction, or assistive tech.
For dyslexic learners, writing deficits may be hidden behind reading issues; spelling and written expression are less visible but equally detrimental for full literacy.
How Writing Helps Reading, Especially for Dyslexic Students
Writing reinforces:
Orthographic mapping: When students write, they more deeply encode letter-sound correspondences, word patterns, and morphological structure.
Phonological awareness and phoneme-grapheme correspondence: Spelling helps solidify these skills in ways that reading alone doesn’t always produce.
Cognitive load reduction: Using scaffolds (graphic organizers, sentence frames), alternative expression, and assistive technology lets students focus on composing meaning rather than getting bogged down in transcription.
Neuroscientific studies show that when reading interventions include encoding (writing, spelling) components, brain activation in dyslexic students shifts toward more typical patterns in both decoding and word recognition regions. PubMed Central+1
Practical Implications
Include explicit writing instruction in reading programs: daily spelling, morphology, handwriting/keyboarding tasks.
Scaffold writing: sentence frames, graphic organizers, modeling, gradual release.
Use assistive tech when needed so that transcription (handwriting or typing) doesn’t block expression.
Monitor writing growth (writing fluency, spelling accuracy, coherence) alongside reading measures, not just reading comprehension or decoding.
Conclusion
If reading is decoding and making meaning, writing is the mirror path: encoding thoughts into print. For students with dyslexia (or other reading difficulties), robust literacy requires both. When writing is overlooked, reading gains are limited. Including writing in interventions doesn’t just help students read better — it helps them think better, read more fluently, and express themselves more confidently.
