Special Education Students Soar with Mathematics Navigator
The Challenge
Using a highly predictive school diagnostic that forecasts failing scores on Florida’s Comprehensive Assessment Test, Chet’s Creek Elementary School recognized that some students were unlikely to pass the mathematics test.
The Solution
The school used Mathematics Navigator to shore up students’ conceptual understanding, skills, and problem solving in specific mathematics topics, including students from the general and special education populations.
The Results
Even though the diagnostic test predicted that they would fail, a third of the special education students passed the state test—and 75 percent exceeded expectations by making a year’s worth of progress on a developmental scale. These special education students face exceptional challenges, yet Mathematics Navigator positioned them to be within reach of the regular curriculum.
100 percent of the students in the general population who received Mathematics Navigator passed the state test.
