While Jake’s busy learning Mandarin in preparation for his trip to China, he’s getting very familiar with things like flash cards, workbooks and all the trappings of a foreign language class. One of the biggest disadvantages of flash cards is their bulk. The more you need to learn, the more cards you need in order to review. Drop a stack of cards and you might spend the next hour trying to reorganize your study aids. Seattle company Positive Motion is trying to change all that. Instead of lugging around a stack of paper cards, you can download cards to your phone using their Mobile Prep cell phone flash cards. Here Chris talks with James Wen, President and CEO of Positive Motion, about using cell phones as learning aides and the future of cell phone based education.
