Nintendo reveals specialized DS software for classrooms
The system can be used for problem sets, with the answers checked automatically and sent to the teacher's PC, surveys, tests, and other multiple-choice activities. In addition, non-multiple-choice questions can be answered by writing or drawing on the DS's touch screen, with screen images sent to the teacher.
The program can be used with any DS, so presumably it's up to schools whether or not they need to provide hardware. We're pretty sure Japanese school kids have easy access to DS systems already.
