Frax is an adaptive, game-based program by ExploreLearning that helps K3–5 students build mastery of fractions through personalized learning. As Data Scientist, I implemented the adaptive logic supporting individualized student pathways. A third-party study meeting ESSA Tier 2 (Moderate) evidence standards found that elementary students using Frax made significantly larger academic growth in math compared to matched non-users.

Key Findings

1. GROWTH BENCHMARKS — 3rd graders using Frax were 1.4x more likely to meet growth projections (equivalent to 5 weeks of additional instructional time); 4th graders were 1.6x more likely (equivalent to 8 weeks).
2. PERCENTAGE OF EXPECTED GROWTH — 3rd graders averaged nearly 16 percentage points more expected growth than non-users; 4th graders averaged almost 28 percentage points higher.
3. GRADE-LEVEL PROFICIENCY — Frax users were significantly more likely to reach or exceed grade-level proficiency in spring regardless of fall achievement level. Students two or more grade levels below were 2x as likely to reach proficiency.
4. EFFECT SIZE — Compared to other educational interventions, Frax was 3x more effective than the average intervention for 3rd graders and 5x more effective for 4th graders.
