Evidence
Research and evidence behind Banana Flip
Banana Flip is built on established reading-science foundations: explicit instruction in phonemic awareness, phonics, and fluency; assessment-informed placement; and data-based adaptation when students need more intensity.
Key takeaway: We target foundational skills with short, structured practice and transparent progress — not gamified guessing or opaque “AI tutoring.”
Reading science foundations
The National Reading Panel synthesized evidence for phonemic awareness, phonics, fluency, vocabulary, and comprehension instruction. Early intervention for struggling readers emphasizes explicit, systematic work in phonemic awareness and phonics, with fluency building as decoding becomes automatic.
Programs like UFLI Foundations illustrate systematic foundational-skills scope and sequence; DIBELS 8 provides a widely used framework for assessing literacy skill acquisition. Banana Flip's instructional design aligns with these traditions without claiming to replicate any single published curriculum.
Assessment and progress logic
A multi-dimensional K–2 checkup samples letter sounds, decoding, phonemic awareness, and related skills. Placement combines screener results with parent observations. Weekly probes track trajectory; adaptation responds to accuracy, latency, and error patterns — not streaks or points.
What Banana Flip measures
- Accuracy and response patterns on targeted activities.
- Oral reading samples during practice (with parent-visible retention policies).
- Weekly probe performance for trend analysis.
What we do not claim
- Clinical or dyslexia diagnosis.
- Guaranteed grade-level outcomes in a fixed number of weeks.
- Replacement for qualified professional evaluation or school special-education processes.
- ESSA tier ratings we have not earned — we describe our logic transparently during the pilot.
How adaptation works
Data-Based Individualization (NCII) intensifies validated interventions through assessment data, progress monitoring, and adaptation. Banana Flip applies this logic in software: adjusting activity selection, item counts, repetition, and scaffold level — then explaining meaningful changes to parents in plain language.
