Texas Instruments touted the use of its TI-Navigator graphing calculator solution, calling it an effective tool for getting students to learn–and talk about–mathematics. The company provided evidence of Navigator’s success by way of an expanding pilot project in the 34,000-student Richardson Independent School District (RISD) in Texas. Administrators say at-risk middle school students participating in the intervention demonstrated a 33-percent increase in statewide standardized test scores in mathematics compared with the previous year. Use of the Navigator system, which enables teachers to deliver targeted, on-the-spot assessments and drill-and-practice exercises, was critical in boosting scores and raising the interest level of this previously low-performing subset of students, administrators say. RISD officials reportedly are looking at ways to expand the program, now in a limited number of schools, across the entire district. http://education.ti.com
