Predictive Vocabulary Support for Stronger Reading Comprehension
Wordflow helps schools address the reading and vocabulary decline by preparing students with the words they’ll need before they read, so comprehension improves without adding work for teachers.
WordFlow uses predictive technology to identify and pre-teach the words students don’t yet know in their upcoming books, delivering them to 99%+ vocabulary coverage before they ever start reading.
Research shows readers need 98-99% word knowledge for adequate comprehension The Language GymLextutor (Hu & Nation, 2000 The Language GymLextutor; Schmitt et al., 2011 ResearchGateWiley Online Library).
By teaching unknown vocabulary ahead of time through gamified daily lessons, students encounter their books with near-complete mastery. Reading becomes contextual reinforcement rather than struggle.
At this level of coverage, learners enter a “virtuous circle” where reading becomes increasingly efficient and enjoyable Wikipedia (Coady & Nation, 1998 UltimatereadingsystemWikipedia).
Instead of hitting unknown words every few sentences, students experience the fluent, immersive reading that builds lifelong readers.
The Problem Schools Are Facing
Across grade levels, teachers see the same pattern:
A. Students can read aloud but can’t explain meaning

B. Complex texts cause disengagement or avoidance

C. Vocabulary gaps limit comprehension across subjects

D. Teachers spend valuable class time rescuing students mid-text
Reading difficulty today is less about decoding and more about language density. When too many words are unfamiliar, comprehension collapses.
Why Vocabulary Is the Missing Link
Research shows students need to understand 98-99% of the words in a text to comprehend it independently. Below that threshold, reading becomes guesswork (Hu & Nation, 2000; Schmitt, Jiang, & Grabe, 2011).
Traditional vocabulary instruction is often:
Reactive (after students struggle)

Generic (not text-specific)

Time-intensive (for teachers)
The result: lowered text complexity, stalled vocabulary growth, and widening comprehension gaps.
The Wordflow Solution
Predictive, not reactive
Students meet key vocabulary before reading, not during or after confusion sets in.
Context-based learning
Words are learned in the context of real texts, not isolated lists.
No extra teacher workload
No new grading, dashboards, or lesson redesigns.
Curriculum-aligned
Supports the texts teachers already assign.
AI That Respects Teachers
Wordflow doesn’t replace instruction or dictate pedagogy. It quietly handles the invisible prep work: text analysis, word selection, and personalization, so teachers can focus on teaching.
AI works best when it stays in the background.
