Lesson Planning for Students with Dyslexia

Dyslexia affects how students process written language — reading is slower, less fluent, and more effortful. But it doesn't affect intelligence, reasoning ability, or the capacity to engage with complex ideas. Lesson planning that conflates reading difficulty with intellectual limitation does profound harm to students with dyslexia.

Effective lesson planning for students with dyslexia removes the barrier of written text where possible, teaches reading as a skill explicitly where needed, and keeps intellectual demand high throughout.

Understand the Profile

Dyslexia is a spectrum, and every student with dyslexia has a different profile. Common features include:

• Slow, effortful decoding — reading accurately but at cost to fluency and comprehension
• Phonological processing difficulty — challenges mapping sounds to letters
• Working memory load from reading — so much cognitive effort goes to decoding that comprehension suffers
• Spelling difficulty that persists even when reading improves
• Strong oral language skills — listening comprehension often far exceeds reading comprehension

The practical implication is that a student with dyslexia who listens to a complex text may comprehend it well; the same student reading the text independently may appear to miss the content entirely. The difficulty is with the decoding process, not with thinking about what the text means.

Reduce the Decoding Load

The most important accommodation in lesson design for students with dyslexia is reducing unnecessary decoding burden. Not all reading serves the same purpose — some reading is about learning content, some reading is about developing reading skill. When content learning is the goal, use formats that don't require decoding:

• Text-to-speech: Most devices now have excellent text-to-speech capabilities. In lesson planning, build in explicit permission and time for students to use TTS when reading is for content comprehension.
• Audio recordings: Pre-record key readings or use existing audiobook versions. For primary sources or complex texts, a teacher-read version with emphasis and pausing is often better than TTS.
• Video and multimedia: For concepts that can be taught visually or through demonstration, video often removes the reading burden while maintaining academic rigor.
• Partner reading: Strategic pairing allows students with dyslexia to access texts through a partner's fluent reading while still engaging with the content.

Separate Reading from Content Assessment

Students with dyslexia should be assessed on their understanding of content, not on their ability to decode text. This means:

• Oral responses as an alternative to written responses when comprehension is being assessed
• Verbal demonstrations of understanding (explaining, narrating, discussing) as valid evidence of learning
• Drawing, diagramming, or building as output modes when writing is a barrier
• Audio-recorded responses when the student can articulate understanding clearly but cannot produce it in writing at the same level

If the objective is "students will analyze the causes of World War I," a student who delivers a clear oral analysis has met the objective. The written paragraph is one way to demonstrate analysis — not the only way, and not always the most accurate measure.

Teach Phonics and Decoding Explicitly — Even in Secondary

Dyslexia doesn't resolve on its own in middle and high school. Students who haven't received structured literacy instruction in elementary school often arrive in secondary with significant gaps that haven't been addressed.

Secondary teachers aren't expected to be reading specialists, but they can:

• Create space for explicit vocabulary and word-level instruction in their content area
• Use morphology instruction (roots, prefixes, suffixes) to build decoding skills for content-specific vocabulary
• Refer students with significant gaps to reading specialists or intervention programs

In lesson planning, morphology instruction can be integrated into vocabulary work — teaching the Latin root "struct" (build) when teaching construct, structure, infrastructure, and deconstruction — in ways that improve both vocabulary and decoding.

Font, Format, and Visual Design

For students with dyslexia who do read print materials, font and formatting choices matter:

• Sans-serif fonts (Arial, Calibri) are generally more readable than serif fonts
• Larger font size (12-14pt minimum for most readers)
• Wider line spacing (1.5 or double-spaced)
• Left-justified text only — full justification creates uneven spacing that increases the cognitive load of tracking lines
• White space between sections
• Dark text on cream or lightly tinted paper (high contrast without the glare of white)

These adaptations benefit students with dyslexia without disadvantaging anyone else — they're good design for all readers.

Spelling and Written Output

Students with dyslexia typically have persistent spelling difficulty even when reading improves. Lesson plans that penalize spelling errors in content-area work (science lab reports, history essays, math explanations) are assessing spelling when they intend to assess content knowledge.

Separate spelling assessment from content assessment in written products. Allow spell-checkers and word prediction software as standard tools. Grade content, reasoning, and argument — not mechanical accuracy, unless mechanical accuracy is the learning objective.

Next Step

Take your next assigned reading and ask: is the goal for students to practice decoding, or to engage with the content? If it's content, build in an audio option. One accommodation, applied consistently, changes a student's relationship to your class.
