How we teach reading

Phonics is the foundation, not an optional layer

Children learn to read by mapping speech sounds (phonemes) to letter patterns (graphemes), not by memorizing words or guessing from pictures. EDU introduces letters by their sound first, teaches letter names only after sound mastery, and never encourages guessing.

Mastery before progression, not exposure before progression

A child does not advance to the next phoneme until they demonstrate mastery of the current one — both in recognition (hearing) and production (saying). Skills are spiraled back on a 1-3-7-14-30-60 day schedule.

Purpose-built assessment, not a chatbot

Our audio pipeline combines an automatic speech recognizer optimized for child speech with a CTC-based goodness-of-pronunciation scorer. The AI's job is to assess, adapt, and encourage — never to entertain or to read for the child when the child should be decoding.

Screen time is a cost, not a neutral resource

Default sessions are 15–20 minutes. We actively encourage offline practice with printable decodable readers and caregiver activities. We do not optimize for time-on-app.

Stage progression

1. Stage 0 — Phonological awareness. Audio-only activities: rhyme, syllable clapping, phoneme isolation and blending.
2. Stage 1 — Alphabetic principle. All 26 letter-sounds, introduced in a frequency- and distinguishability-weighted order.
3. Stage 2 — CVC decoding. Short-vowel consonant-vowel-consonant words and the first decodable sentences.
4. Stage 3 — Expanded phonics. Digraphs, blends, silent-e, vowel teams, r-controlled vowels, soft c/g, diphthongs.
5. Stage 4 — Fluency. Repeated reading, choral reading, prosody; end-of-Grade-1 target is 60 WCPM with 95%+ accuracy.
6. Stage 5 — Comprehension. Predicting, questioning, visualizing, summarizing, inferring.
7. Stage 6 — Independent reading. Chapter books, reading volume tracking, dialogic prompts for parents.
