Miami-Dade County Public Schools in Florida is the fourth largest school district in the United States with over 390 schools and 345,000 students. ExploreLearning has worked with the district for over a decade — first with Gizmos, math and science online simulations, and then with Reflex, an adaptive game-based math fact fluency system.
The National Assessment of Educational Progress (NAEP) is the largest nationally representative and continuing assessment. Between 2009 and 2013, Miami-Dade’s NAEP grade 4 math scores remained relatively unchanged. In 2013, they purchased Reflex for all their elementary schools and provided economically disadvantaged focus schools with laptops and Wi-Fi so students could work on Reflex outside of school.
Miami-Dade enjoys success with Reflex
In 2015, Miami-Dade’s grade 4 math NAEP scores increased by 5 points – opening an 8-point gap over their peer large city districts and surpassing the national average for the first time (chart 1). Economically disadvantaged students grew even more, scoring 11 points above the large city district average and 9 points higher than economically disadvantaged students nationally.
“Reflex has helped Miami-Dade County Public School students in grades 2-8 gain basic math fact fluency, a fundamental skill which opens the door to higher mathematics. We have also noticed that the past three years of usage coincide with the increase in our fourth-grade NAEP mathematics scores.”

Math fact fluency predicts student success
Research shows that math fact fluency predicts student success across many types of mathematical tasks because it makes learning new mathematical concepts and skills easier by reducing the burden on working memory associated with doing basic computations. After using Reflex, Miami-Dade student scores went up across all areas with scores in the computationally intensive properties and operations strand showing the most improvement with a 7-point gain (chart 2).
Reflex helps all students succeed
Extensive research has demonstrated the critical role of fact fluency in elementary school-level mathematics and beyond and is underscored by studies that show it is a significant predictor of performance on standardized tests. Fluency also predicts performance on math concept problems, word problems, data interpretation problems, and mathematical reasoning items as well.
Across multiple grade levels and assessments, students who use Reflex are scoring higher and growing faster than their peers.
