 The world is changing. Today, it's not enough for kids to know, they need to know what to do. I'm a scientist who spent the last 10 years figuring out how technology can help with this in science education. Instead of memorizing facts and figures, imagine a world where we fire students' curiosity through amazing virtual journeys, challenge them through simulations, and help them with AI tutoring. I've discovered that all that's possible now with the right digital tools delivered through inexpensive smartphones and web browsers. Not just for some kids, for all kids. But these experiences aren't in many classrooms yet. Why not? It's because we build them one size fits all. They aren't tailored to meet the particular needs of particular students in particular classrooms, so teachers don't use them like they could. My audacious project expands a tested concept, the digital teaching network. It's a platform that empowers any teacher to create, customize, and share the amazing digital experiences that they need. The open source movement empowered programmers desktop publishing empowered writers, digital photography empowered filmmakers. It's time for technology to empower teachers.
