Ehri's Phases of Word Reading Development

FoRT framework (Objectives 0002 & 0009): Apply knowledge of Linnea Ehri's developmental phases of word reading to analyze student reading and spelling miscues, determine instructional entry points, and design targeted phonics interventions.

The Architecture of Word Reading Development

Dr. Linnea Ehri's Phases of Word Reading Development describe the qualitative cognitive shifts children undergo as they learn to read printed words. Unlike older stage theories that viewed reading as a progression of generic visual milestones, Ehri's model explains how the alphabetic principle and orthographic mapping transform the brain's reading circuitry from visual cueing to automatic, chunked word recognition.

Phase 1: The Pre-Alphabetic Phase

Cognitive Characteristics & Reading Behaviors

• Non-Phonetic Visual Cueing: The child does not understand that letters represent speech sounds. Words are identified solely by incidental visual cues, physical shapes, colors, or surrounding environmental logos.
• Examples:
  • "Reading" the word STOP on a red octagonal sign, but failing to recognize the word stop printed in lowercase black font on a white card.
  • Remembering the word look because the double oo looks like "two eyes looking at you."
  • Remembering the word yellow because it has two tall sticks (ll) in the middle.

Spelling & Writing Characteristics

• Scribbles and Unrelated Letter Strings: Writing consists of mock letters, random strings of known letters, or drawings that bear no phonological relationship to spoken sounds (e.g., writing "KTRX" for the word cat).

Diagnostic Miscues on the FoRT

• When shown the word dog, the student might say "puppy" because the picture shows a dog.
• If a visual cue is altered (e.g., changing the word PEPSI to XEPSI on a familiar soda can), the pre-alphabetic child will still read it as "Pepsi" because they are reading the visual logo, not the letters.

Instructional Road to the Next Phase

• Phonological awareness (syllable clapping, initial sound isolation: /s/ in sun).
• Letter names and letter formation (rapid uppercase and lowercase identification).
• Basic letter-sound correspondence for high-utility consonants (m, s, t, p) and short vowels (a, i).

Phase 2: The Partial-Alphabetic Phase

Cognitive Characteristics & Reading Behaviors

• Emerging Alphabetic Insight: The child understands the alphabetic principle but possesses incomplete letter-sound knowledge and weak phonemic segmentation.
• Salient Letter Cueing: The child relies on the most acoustically prominent letters in the word—almost always the initial consonant, and occasionally the final consonant—to guess the word. The child routinely ignores medial vowels.

Spelling & Writing Characteristics (Semi-Phonetic / Invented Spelling)

• Children write the initial and final consonant sounds while omitting medial vowels entirely:
  • boat $\rightarrow$ spelled BT
  • duck $\rightarrow$ spelled DK
  • fish $\rightarrow$ spelled FS or FH
  • lamp $\rightarrow$ spelled LP

Diagnostic Miscues on the FoRT

• Encountering the printed word spoon and reading "sun" or "spin" (sees s and guesses based on initial sound).
• Encountering ball and reading "bell" or "bull" (cannot differentiate medial vowel sounds).
• Over-relying on picture cues whenever the first letter matches multiple possibilities.

Instructional Road to the Next Phase

• Medial Short Vowel Discrimination: Isolating and segmenting vowels in CVC words using mirrors, physical mouth movement analysis, and Elkonin sound boxes.
• Full Phonemic Segmentation: Segmenting all 3 sounds in spoken CVC words (/h/ /æ/ /t/).
• Continuous Blending Instruction: Teaching students to blend all sounds without pausing between consonants and vowels.

Phase 3: The Full-Alphabetic Phase

Cognitive Characteristics & Reading Behaviors

• Complete Phoneme-Grapheme Mapping: The reader possesses extensive knowledge of the alphabetic code and can segment spoken words into all constituent phonemes.
• Sequential Decoding: The student reads unfamiliar words by sequentially decoding every grapheme from left to right, including initial consonants, medial vowels, and final consonants/blends (/s/ /t/ /ɒ/ /p/ $\rightarrow$ stop).
• Ignition of Orthographic Mapping: Because the student can match every spoken sound to every printed letter, newly encountered words are rapidly mapped into permanent sight memory in just 1 to 4 exposures.

Spelling & Writing Characteristics (Full Phonetic Spelling)

• The child represents every single sound in their spelling, even if the orthographic choice is conventional or unconventional:
  • plane $\rightarrow$ spelled PLAN or PLNE
  • feet $\rightarrow$ spelled FET or FETE
  • high $\rightarrow$ spelled HI or HY
  • boat $\rightarrow$ spelled BOTE or BOT

Diagnostic Miscues on the FoRT

• Reading is accurate but may be slow and laborious as the student sequentially decodes sound by sound.
• Misapplying a known rule to irregular words (e.g., reading said as /seɪd/ using silent 'e' or vowel team logic).

Instructional Road to the Next Phase

• Introducing complex vowel teams (ai/ay, ee/ea, oa/oe), diphthongs (oi/oy, ou/ow), and r-controlled vowels (ar, er, ir, or, ur).
• Teaching common inflections (-ed, -ing, -s, -es) and basic syllable division rules.
• Fluency-building routines with decodable and transitional texts to build automaticity.

Phase 4: The Consolidated-Alphabetic Phase

Cognitive Characteristics & Reading Behaviors

• Orthographic Chunking: Rather than processing individual graphemes one by one, the reader's brain recognizes recurring multi-letter chunks, morphemes, syllables, and word families as unified cognitive units.
• Key Consolidated Units:
  • Common Affixes: un-, re-, dis-, pre-, -tion, -ment, -able, -ful
  • Syllable Patterns: Closed, Open, VCe, Vowel Team, R-Controlled, Consonant-le
  • Phonograms / Rimes: -ight, -ound, -eam, -atch, -ought
• Fluency & Multisyllabic Mastery: The reader effortlessly decodes long, multisyllabic words by dividing them into recognizable morphemes and syllables (un-com-fort-able).

Spelling & Writing Characteristics (Conventional / Morphological Spelling)

• Spelling reflects mature morphological and orthographic knowledge:
  • Correctly applying doubling rules (hop $\rightarrow$ hopped vs. hope $\rightarrow$ hoped).
  • Accurately spelling Greek and Latin roots and derivational affixes (construction, photography, impossible).

Diagnostic Miscues on the FoRT

• Miscues occur primarily on rare, low-frequency Tier 3 vocabulary or unfamiliar multisyllabic loanwords.

Instructional Road to Advanced Literacy

• Advanced morphological analysis (Greek and Latin roots and combining forms).
• Disciplinary vocabulary acquisition and reading comprehension strategies in complex informational and literary texts.
