Smart phones are being used to help math students

At six high schools in North Carolina, students are participating in a corporate-sponsored experiment using school-issued smart phones to help them learn math. Figuring out how to use the phones effectively in the classroom is a "learning process," says one educator, but teachers and students say math concepts are being better understood, and students are even using the phones at home to record how they solved math problems and sharing the solutions with their classmates.
