I would argue that there’s another, more immediate educational use for wearables, one that students can benefit from even without laying their hands on the hardware: dreaming up software for the devices. In this month’s story on using Google Glass in the classroom, we found three early-adopter institutions encouraging students to design apps for the head-mounted technology. A course at Northeastern University, for instance, challenges students to create Glass apps that will help people make behavioral changes to improve their health. It’s an ingenious way to engage students and hit all the right education buzzwords — project-based learning, digital literacy and futurist technology rolled into one. Even better, the focus on software means students don’t have to fork out $1,500 for their own Glass headset (not exactly affordable in a world of skyrocketing tuition and textbook costs).
