The Gear Up III Creating a Vision project is a mathematics education intervention program implemented in 7 small school districts in the rural area surrounding the Laredo, Texas area with primarily Hispanic students. The 2008-2009 academic
year was the first year of implementation using the TI-Navigator system with TI-84 graphing calculators. High performing students increased their TAKS scores significantly, while the program had no effect on low performing students.
Caution should be used when generalizing these results due to a number of complicating factors including severe student data attrition and a lack of control groups
