Using the DS as an educational tool is nothing new in Japan. It's been a tour guide, an English teacher and even a boozing instructor. Lately the focus has been on DS Classroom, a program from Nintendo and Sharp System Products announced back in June that aims to let Japanese teachers dish out lessons and the like to students' DSes. Initially, it was planned to work with the original DS, the Lite and DSi, but, according to Andriasang, that's no longer the case.
The new educational aid will only work with the DSi now, as Nintendo has announced it's doing away with support for the older Nintendo handhelds. We would be worried for the students over there that don't have a DSi, but, then again, we're pretty sure those kids are few and far between.
